[Proposal Example] Straight bevel gear to zero bevel gear
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.
Leave it to Oujik, which has a specialized factory for bevel gears!
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.
Simulation using the analysis software KIMOS.
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.
Improving noise and the convenience of assembly.
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.
Supports strict dimensional control of chamfer shapes, tooth base shapes, and more.
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.
Improvement of noise issues through optimization of the tool for treatment.
This is a gear for table rotation of a scientific analysis device. Due to the thin-walled and easily distorted shape of the product, the difficulty of production was high, and there were no manufacturers capable of producing it, leading to an inquiry to our company. By utilizing the know-how we have accumulated in the manufacturing of small-shaped gears, we implemented changes to lightweight jigs, managed tightening torque, and optimized hob coating, achieving stable processing including the spline section. Under the condition of finishing with gear cutting, we were able to significantly improve to JIS Class 1 standards in terms of noise and vibration. The noise issue often arises from shape changes due to distortion, but by producing stable products, we were able to meet the specified noise levels.
Achieving stability and high quality with state-of-the-art processing and inspection equipment.
We received an inquiry from our customer regarding the stable quality of gears for railway vehicles and cost reduction in procurement. Our company has achieved low prices by handling all processing in-house, except for the heat treatment process. Additionally, we have established a high-level quality management system, a temperature and humidity-controlled factory managed 24/7, and state-of-the-art processing and inspection equipment to ensure stability and high quality.
Not only the reduction of noise/vibration but also the stability at high rotation speeds has increased.
We received an inquiry from a customer regarding gears used in the main spindle of machine tools, expressing a desire to reduce noise. To address this, our company calculated the optimal meshing ratio for noise reduction and proposed gears with less noise and vibration. The customer adopted our proposal, and upon actual operation, we were able to reduce noise and vibration compared to before. In addition to reducing noise and vibration, we also achieved improved stability during high-speed rotation.
Improvement of tooth surface damage with the proposal of zero-roll bevel gears.
Due to deformation of the gear case during operation, stable meshing could not be ensured, resulting in tooth surface damage. It was determined that the cause of the gear case deformation was the thrust force generated by the spiral bevel gears. Therefore, we proposed to the customer to switch from spiral bevel gears to zerol bevel gears. As a result, the reduction in thrust force helped suppress the deformation of the gear case, allowing us to maintain the correct assembly distance. Consequently, the meshing became stable, and the damage was improved.
Proposal for a manufacturing process that enables a monocoque structure to eliminate vibration and noise issues!
We improved the bevel gear used in the turret of a machine tool lathe. The challenge was to eliminate the vibration and noise issues of the bevel when operating at high speeds. We confirmed that the vibration was caused by backlash at the joint due to the spline and bevel being manufactured separately. We proposed a manufacturing process that could create a unified structure for our customers. By integrating the shaft and bevel, we reduced vibration, which also contributed to noise reduction in the bevel teeth. Assembly was simplified, leading to a reduction in labor costs as well.
Tooth contact design software TCA, reproducing the tooth contact of design defects with the know-how of OJIC.
This is a worm gear used in the tables of machine tools. We received an inquiry from a customer regarding a competitor's worm gear they were using, which had poor tooth contact and needed improvement. By using our tooth contact design software TCA (Tooth Contact Analysis), along with the latest machining equipment and engagement inspections, we can reproduce the intended tooth contact as designed. By adopting our worm gear, the tooth contact has improved, leading to a reduction in assembly man-hours and an increase in durability.
Identify the optimal processing conditions suitable for gear specifications and improve the issue of gear burning.
This is a helical gear used in the new transmission unit of a tractor. The material is SCM, and it has undergone carburizing and quenching as heat treatment. In processing this helical gear, the burning of the tooth surface was one of the challenges. By repeatedly conducting prototype machining at our company, we identified the optimal processing conditions suitable for the gear specifications. As a result, we were able to eliminate the burning of the tooth surface and achieve the production of products as per our customer's requirements. Our company is capable of manufacturing gears that meet the specific requests from our customers, as demonstrated in this case. We engage in technical consultations to jointly pursue the most suitable gears for our customers. For any inquiries related to gears, please feel free to consult with OJIC.
By using analysis software, we can examine the specifications and propose appropriate ones!
This is a bevel gear used for power transmission in electric bicycles. Initially, we received a request to create a prototype, with mass production also in consideration. Since it was a component for a bicycle, it needed to be lightweight, and there were size limitations for the gear box as well. Additionally, because it involved a hybrid drive between the motor and pedaling power, selecting the specifications was a very challenging case. The size was a gear with a diameter of Φ50 to 200 and a module of 2.5. At our company, we first used analysis software to consider the specifications. We then proposed specifications that would fit within the size constraints of the gear box. As a result, we are currently engaged in activities toward actual prototype development based on the specifications proposed by OJIC.
