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.

[Technical Column] What is a Hasp Gear (Helical Gear)?

[Technical Column] What is a Hasp Gear (Helical Gear)?

Explanation of features and uses! It has an appearance as if the teeth are cut at an angle.

A helical gear is called "hasuba" in Japanese. While a spur gear, which is commonly imagined as a gear, has straight teeth, a helical gear has spiral-shaped teeth, giving it an appearance of being cut at an angle. For this reason, it is referred to as a helical (hasuba) gear. *You can view the detailed content of the column through the related links. For more information, please feel free to contact us.*

Custom Gear Manufacturing Case Study: Quality Improvement Case 2 with Helical Gears

Custom Gear Manufacturing Case Study: Quality Improvement Case 2 with Helical Gears

Proposing helical gears with increased tooth surface strength.

The spur gears used in industrial machinery were not compatible with the customer's usage conditions and the strength of the product, resulting in severe damage to the spur gears being used. The customer requested the production of similar gears for replacement, but we proposed a design change to a helical gear specification with increased tooth surface strength compared to the current situation. The customer adopted the change to the helical gear specification that could withstand the operating conditions. As a result of the specification change, the instances of damage were significantly improved.

Helical gears for transmissions for electric vehicles e-axle

Helical gears for transmissions for electric vehicles e-axle

Evaluation of tooth surface characteristics is possible with GDA software! It focuses on evaluating tooth surface properties that could not be assessed with conventional gear measuring machines.

This is a product example of gears used as a reduction gear for electric vehicles' e-axles. Specifically, these are helical gears used in transmissions. The gears rotate at high speeds, such as 15,000 rpm, requiring high quality. Due to the need for precise evaluation of the tooth surface shape, we conducted an assessment of the tooth surface flatness using the GDA software we possess. We feel that this evaluation could only be performed by our company, which specializes in gear manufacturing, and it was a measurement that would be difficult for other companies to achieve. As a result of the measurements taken with the GDA, it was found that changing the processing conditions could yield higher manufacturing precision. Additionally, we have measuring equipment capable of maintaining and managing tooth profile corrections within a few micrometers, allowing us to manufacture while appropriately maintaining and managing the process. Furthermore, we proposed that by polishing the tooth surface to a mirror finish, we could reduce tooth surface damage, vibration, and noise. In fact, by focusing the evaluation on tooth surface characteristics that could not be assessed with previous gear measuring machines, we have been able to evaluate the effectiveness of polishing grinding and low-noise shifts.

Custom Gear Manufacturing Case Study: Helical Gear for AGV Drive Mechanism

Even with difficult shapes, it maintains the correct tooth profile shape and pitch accuracy!

This is a case of helical gears for drive wheels in an automatic transport device. The gears themselves are lightweight, yet they are components required to move heavy objects. In such cases, quiet operation is essential, but the thin-walled blank shape is prone to distortion, making process design and distortion management to maintain machining accuracy very challenging. At OJIC, we are equipped with advanced process design and distortion control based on our extensive experience and achievements, as well as state-of-the-art machining and inspection equipment. Additionally, for thin-walled products, the method of securing the product during each manufacturing process is crucial, so we provide support starting from the design of fixtures that ensure stable positioning during machining. As a result, despite the thin-walled and distortion-prone shape, we were able to maintain the correct tooth profile and pitch accuracy, receiving positive feedback from our customers.
