This is a spur gear used for driving semiconductor manufacturing equipment. Due to the need for corrosion and rust prevention, electroless nickel plating was required, which necessitated strict dimensional control, including the shape of the chamfer and the shape of the tooth root. Through quality control systems during the processes and final inspections, along with our long track record in manufacturing pump gears, we have been able to ensure stable precision. In particular, since a high degree of variation in quality can impair the functionality of the gears as pumps, a balance of precision, quality, and price is essential, and we have received comprehensive satisfaction from our customers. By entrusting us with this project, we have been recognized for improving product stability, resolving assembly yield issues, and significantly enhancing work efficiency.

• gear

This is a bevel gear used in turret systems for machine tools. As machine tools are advancing towards higher rotational speeds, there is a demand for products that can operate stably under high-speed conditions for bevel gears. The challenge was to maintain quality while ensuring cost performance. When it comes to the condition of a bevel gear, both the gear and the pinion require higher precision. By ensuring balance and the precision of each product, we focused on enhancing the overall precision of the set. Although the product configuration has strict conditions for vibration and noise at high speeds, we were able to solve these challenges through years of accumulated know-how, leading to the launch of the new product. During the development phase, comparative prototypes were also made using gears from other companies in addition to our own. Among these, our products were highly evaluated for their noise levels and ease of assembly compared to those from other manufacturers, leading to their adoption.

• gear

This is a spur gear for manufacturing equipment for vehicle batteries. We received feedback that its thin-walled design makes it difficult to achieve precision, resulting in unstable quality. The deformation during heat treatment is significant, making it challenging to maintain the product's shape, and further special surface treatments are required. Due to the importance of managing the film thickness, it was a product with difficult dimensional management. Many of our partner companies are manufacturers capable of handling special processing. By not only focusing on standard gear processing but also establishing a system to accommodate special processing, we have enhanced the product's completeness. For production, we implemented process design considering distortion, created fixtures that are resistant to distortion, and performed dimensional management taking surface treatment into account, which allowed us to stabilize product quality. With the stabilization of quality, adjustments during assembly became possible, resolving issues related to precision defects such as initial vibrations.

• gear

This is a sensor ring gear used for position detection of the rotating shaft in machine tools. The indexing accuracy is of utmost importance for the gear that detects the indexing position of the spindle. If the indexing accuracy is poor, it will affect the machine's precision during indexing and consequently impact the accuracy of the processed workpiece. To improve accuracy, our company has applied the high-precision gear processing technology cultivated through worm machining, enabling us to achieve precision that cannot be addressed by conventional gear cutting processes. Based on our long-standing expertise in sensor processing, we are able to propose material changes and enhance the precision of blanks, thereby stabilizing the processing. Additionally, by improving the precision of the tools, we optimize the processing accuracy of the gears and achieve high precision. The impact of our high-precision hob machines is significant, allowing us to perform high-precision finishing processes that are difficult for other companies to replicate. Although the gears are challenging due to the need to ensure precision in cutting and finishing processes, we have significantly improved the accuracy as a sensor, enabling us to meet our customers' development needs.

• gear

This is a bevel gear for angle heads used in machining equipment. Due to grease lubrication, we received inquiries about persistent abnormal wear. Our investigation revealed that the cause of the abnormal wear was the lack of an appropriate gap (backlash). To resolve this, we conducted a specification analysis for the customer and proposed changes. Using the analysis software KIMOS, we simulated to create gears that matched the customer's operating conditions, and we revised the specifications to ensure appropriate tooth contact and backlash. By providing optimal specification proposals based on years of experience in specification analysis, the abnormal noise and wear that had occurred were eliminated. Furthermore, we were able to meet the demands for higher rotational speeds, ensuring more stable operation.

• gear

This is a high ratio hypoid gear for a dividing device. It can be manufactured with carburized material and ground tooth finishing, achieving both high strength and high precision. To realize a large reduction ratio of 1:30 within a limited product size, it was difficult to design the tooth surface with a pinion having only 2 teeth, which is not typical for hypoid gears. Additionally, due to the high sliding speed of the tooth surfaces, significant heat generation occurs, leading to changes in gear clearance and worsening operating conditions. To reduce heat generation, we determined that the following key items were necessary: 1. Improvement of surface roughness (selection of grinding wheels and optimization of processing conditions during manufacturing) 2. Optimization of tooth shape (increasing transmission error during design). With our long-standing expertise, we implemented surface roughness improvement techniques and tooth surface design, allowing for adjustments in sliding speed through tooth shape correction. As a result, we were able to achieve a very high transmission error, contributing to the production of a very compact gearbox. We successfully provided products that maintain accuracy equivalent to that of worms without any burning of the tooth surfaces.

• gear

Spiral bevel gears place less burden on the teeth and are expected to perform well in applications where strong machinery and other performance factors are prioritized. Hypoid gears have axes that are misaligned (not parallel and do not intersect) and feature spiral-shaped teeth. Their high engagement rate and good power transmission efficiency are notable advantages. Ozig has a factory specializing in bevel gears and has numerous processing achievements, primarily serving machine tool manufacturers and automotive manufacturers. We have compiled a list of various questions we have received so far, so please take a moment to read through it. 【Sample Questions】 ■ Can you process high-ratio hypoid gears for robots? ■ How does the cost of bevel gear lapping compare to gear grinding? ■ Is it possible to measure the engagement of hypoid gears? 　　　　　and more There are very few manufacturers capable of processing bevel gears, and even fewer that specialize in them, so please trust Ozig, which has strengths in bevel gears. *For more details, please refer to the PDF document or feel free to contact us.

The strength design of gears, like the design of general machinery, is carried out with the aim of preventing damage, and among various designs, strength design occupies a particularly important position. The strength design for gears is mainly conducted regarding: - Bending strength of the teeth - Surface pressure strength of the teeth - Scoring strength of the tooth surface against seizure. There are many types of gear damage, but they can be broadly classified into two categories: tooth breakage and surface damage. Common examples of tooth breakage include fatigue breakage and overload breakage. Fatigue breakage occurs when a load is repeatedly applied that generates bending stress exceeding the material's fatigue limit at the root of the tooth, leading to cracks that initiate from the root fillet and propagate, causing tooth breakage. Overload breakage occurs when an extremely large overload acts on the tooth, resulting in breakage due to one or a few repetitions of slight loads. As for surface damage...

Many people may be troubled by the noise of gears (gears). The noise from gears is caused by various factors. Depending on the cause, it may be easily resolved, or it may be difficult to identify the cause. When you notice noise from gears, it is important to check all parts that could be considered as potential causes. Typical causes of gear noise include: - Dents and scratches - Surface roughness of the teeth - Backlash - Engagement ratio, etc. If the cause of the gear noise is unknown, we recommend checking the gears following the steps below: 1. Visually inspect the relevant gear parts (check for scratches, dents, etc.) 2. Confirm the installation condition (check if they are aligned properly, etc.) 3. Check from the gearbox. If you still cannot identify the cause of the noise after checking, please feel free to consult us. Our company specializes in producing gears with high quietness, so we can significantly reduce noise. ↓↓ For more details, click here ↓↓

Backlash refers to the intentional gap created between gears. If there is no gap between the gears, the transmission of rotational motion becomes poor, and further wear between the gears can lead to their deterioration. In other words, the presence of this backlash allows the gears to perform rotational motion smoothly. However, it is not enough for this backlash to simply exist; it is important that it is of an appropriate size. - In the case of spur gears and helical gears: For spur gears and helical gears, backlash refers to the gap or play on the pitch circle of a pair of meshing gears. The size of this backlash can be determined according to the JIS accuracy grade. The sum of the minimum values calculated from the face module (size of the gear) and the pitch circle diameter of a pair of gears is defined as the minimum backlash, while the sum of the maximum values is defined as the maximum backlash. Depending on the intended use of the gears, values for backlash can be adopted that differ from the accuracy grades. ↓↓ Click here for the measurement method of bevel gears ↓↓

Year by year, there have been demands for quality improvement from end users. In mechanisms using straight bevel gears, there were significant noise and vibration issues that adversely affected the processed products. Due to the characteristics of the processing machine, straight bevel gears can only undergo finishing processes before heat treatment, which led to variations in quality due to heat treatment distortion, making quality improvement difficult. In response, our company proposed zero bevel gears that can undergo finishing grinding after heat treatment, implementing quality improvements through gear grinding specifications. Noise and vibration were significantly improved as well. Additionally, unlike spiral bevel gears, the twist angle is 0 degrees, so there was no need to change surrounding designs such as bearings. This resulted in reduced assembly work and improved end-user satisfaction, which was greatly appreciated.

The projection welding using jigs offers high precision and stability in the joining position and posture. Direct joining through melting between the base pipes achieves high welding strength, and since there are no protrusions from the branch pipe (thin pipe) into the inner diameter of the main pipe (thick pipe), the flow within the main pipe becomes smooth. The inflow holes can be processed after welding, allowing for free selection of hole diameters below the inner diameter of the branch pipe. Therefore, it is also possible to restrict flow with small holes, enabling processing tailored to customer needs. Seien Co., Ltd. is part of the Oujic Group, just like Oujic Co., Ltd.
