Transmission Ring Gear

Our transmission ring gear is designed for transmission systems and related mechanical power transmission applications. Each product can be manufactured according to customer technical drawings, existing prototypes, and specific project requirements. This makes it suitable for customized equipment projects, replacement component sourcing, and repeat production orders.

A wide range of steel materials can be processed, including 20CrMnti, 42CrMo, 40Cr, #45 Steel, 20CrNiMo, 18CrNIMo7-6, and 17CrNiMo6. Other steel grades that can be normally sourced in China may also be considered according to the actual project. Aluminum and copper components are currently not supported.

The standard machining diameter ranges from 50 mm to 1000 mm, while the maximum diameter is limited to 2000 mm. The final appearance depends on the processing stage. After shot blasting, the surface is normally black-gray. After grinding, the surface becomes bright white.

Hangzhou Kaishen Machinery Co., Ltd. was established in 2015 and focuses on high-precision gears, clutch assemblies, and transmission components. The company has established complete gear machining and heat treatment production lines. Its team covers engineering, production management, and quality inspection, with practical experience in gear machining, heat treatment processes, and equipment adjustment.

For a custom transmission ring gear project, material confirmation, process planning, production tracking, and quality inspection can be coordinated within the same manufacturing workflow. Customers can provide technical drawings or prototypes for evaluation and production. OEM and ODM services are also supported.

For new projects, sample development can be arranged before volume production. The normal development time for customized samples is approximately 45–90 days. The minimum order quantity is 2,000 pieces for the same specification.

For mature products, a normal batch production cycle is approximately 30 days. Customized projects generally require 45–90 days, depending on the product and manufacturing requirements.

Repeat orders for the same product can reduce the preparation time associated with producing molds and customized tooling again. This can help purchasing teams coordinate replenishment, inventory planning, and future production schedules more efficiently.

During production, photos or videos can be provided upon request. Hangzhou Kaishen Machinery Co., Ltd. also assigns personnel to record and track delivery progress, giving buyers clearer visibility into the status of their orders.

Quality control for each transmission ring gear includes production-stage sampling inspection and finished-product sampling inspection. Before packaging, the appearance of each product is checked individually. The factory is equipped with professional inspection equipment and can also cooperate with third-party inspection when required. Additional inspection requirements can be discussed during order confirmation.

Finished products can be packed in wooden cases or on pallets. Export orders use wooden case packaging to support handling and transportation. A one-month warranty is provided.

From drawing review and material confirmation to machining, inspection, packaging, and delivery tracking, the manufacturing process is organized to support both initial customized projects and long-term repeat purchasing.
