[Production Example] Prototype Hypoid Gears with Short Lead Time and Low Cost

A must-see for the automotive industry! We are applying a data link system to the final gear grinding process.

Our company manufactures "prototype hypoid gears" with short lead times and low costs. For the production of small quantities of bevel gears, grinding can be performed from solid materials without cutting processes. This method allows for economical and quick processing for prototypes or small production runs without the need for expensive cutting tools that require long lead times. By applying a data link system in the final grinding process, it is possible to produce gears according to the design specifications. Performance that withstands noise and load can be directly fed back to the designers. 【Production Examples】 ■ Grinding can be performed from solid materials without cutting processes ■ Economical and quick processing can be done without preparing cutting tools ■ A data link system is applied in the final grinding process ■ It is possible to produce gears according to the design specifications ■ Performance that withstands noise and load can be directly fed back to the designers *For more details, please refer to the PDF document or feel free to contact us.

Why does gear noise occur?

Introducing the typical causes and countermeasures for gear noise!

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 ↓↓

Custom Gear Production Case Study [Zero Roll Gear Prototype]

We propose a design that improves tooth surface accuracy and enhances surface pressure strength, along with zero-roll bevel gear grinding processing!

When we received a manufacturing consultation from the customer, the issue at hand was that while we were currently addressing it with straight bevel gears, there was a lack of tooth surface strength in the product. To solve this problem, our company proposed improving gear precision and increasing the design flexibility of the tooth surfaces through gear grinding. We implemented a design that could enhance tooth surface precision and improve surface pressure strength using analysis software, and we proposed a zero-roll bevel gear grinding solution. As a result, we were able to increase strength compared to conventional products, confirming that it could withstand greater transmission power and larger loads while maintaining the same size, allowing us to proceed to practical application.

An internal gear is a gear with teeth formed on the inside of a cylinder or cone.

An internal gear is a gear with teeth formed on the inside of a cylinder or cone. It is commonly used in planetary gear mechanisms. A regular gear is an external gear. The counterpart that meshes with an internal gear is always an external gear. Internal gears do not mesh with each other. Furthermore, the internal gear is always the larger gear, while the meshing external gear is always the smaller gear. The smaller gear is referred to as a pinion.

Hiroshima Seiki Co., Ltd. Product Introduction "Gears"

Exploring the unknown technologies of Hiroshima Seiki Co., Ltd., a group of professionals in manufacturing.

Hiroshima Seiki Co., Ltd. is a specialized manufacturer of gears based in Hatsukaichi City, Hiroshima Prefecture. Gears are essential for all types of machinery, but their manufacturing requires precision machining technology at the micron level. As a result, even major manufacturers representing Japan, such as those in machinery, electronics, automotive, and steel industries, often have no choice but to rely on the technical expertise of specialized manufacturers for gear production. Leveraging such unique technology, Hiroshima Seiki engages in transactions with a wide range of manufacturers and provides gears. 【Types of Gears (Examples)】 ○ Spur Gear → A gear with teeth that are parallel to the axis of rotation → The most common type of gear ○ Helical Gear → A gear with teeth that are angled relative to the axis ○ Bevel Gear → A shape resembling two helical gears combined ○ Worm Gear → A conical gear that transmits power between axes that intersect vertically or horizontally ○ Rack → A flat plate or rod with teeth cut into one side For more details, please contact us or download the catalog.
