Proposal 1 for Straight Bevel Gear to Zerol Bevel Gear

Proposal 1 for Straight Bevel Gear to Zerol Bevel Gear

[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.

Custom Gear Production Example [Bevel Gear for Machine Tools - Angle Head Side]

Custom Gear Production Example [Bevel Gear for Machine Tools - Angle Head Side]

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.

Custom Gear Manufacturing Case Study [Spiral Bevel Gear ⇒ Zerol Bevel Gear Proposal]

Custom Gear Manufacturing Case Study [Spiral Bevel Gear ⇒ Zerol Bevel Gear Proposal]

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.

Custom Gear Manufacturing Case Study: Integration Improvement of Bevel Gears for Machine Tools

Custom Gear Manufacturing Case Study: Integration Improvement of Bevel Gears for Machine Tools

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.

Custom Gear Production Case Study [Gearbox for Electric Bicycles]

Custom Gear Production Case Study [Gearbox for Electric Bicycles]

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.

Custom Gear Manufacturing Case Study: High-Speed Helical Gear for Turbo Refrigeration Unit

Custom Gear Manufacturing Case Study: High-Speed Helical Gear for Turbo Refrigeration Unit

By considering distortion in the process design, it is possible to manufacture gears with low vibration and noise even at high speeds!

This is a helical gear used in turbo refrigerators. The material is SCM, the shaft length is 1000mm, and it has undergone carburizing and quenching as heat treatment. Since it is a gear used in high-speed rotating parts, it is necessary to minimize the deflection of the long pinion shaft. Additionally, the balance of the gear is also a very important point, requiring high-precision geometric tolerances such as roundness and perpendicularity. We have designed the process considering distortion, and through our latest equipment and processing technology, we have achieved high-precision tooth profile correction and surface characteristics. Furthermore, we have also realized cost reduction by using different materials for the shaft and gear, as well as high precision through shrink fitting. As a result, even with high-speed rotation, it has become possible to manufacture gears with low vibration and noise. Our company specializes in the production of highly quiet gears like the one in this case. Please feel free to consult us regarding any gear-related matters.
