Customized main transmission forged steel large diameter spur gear

1. Overview

We can produce large forged, cast and welded gears according to customer drawings. According to working conditions and customer requirements, we can also perform gear grinding, surface hardening, cementation quenching, nitriding quenching, etc.

2. Production process

-Forging

-Heat treatment

Customized large diameter spur gear-quenching and tempering If the gear module is large (above M25), the first hobbing is performed before heat treatment. According to this way, the hardness depth of the gear teeth will be deeper after QT, which can improve the mechanical properties of the gear teeth and can extend the service life of the gear.

-Gear processing

2-3 times of precision hobbing to ensure its gear accuracy and surface roughness. Only in this way can the spur gear work well with large gear rings or gear shafts.

Complete hobbing of large diameter ring belt gears

The maximum accuracy level is 8 and the grinding accuracy level is 6.

-Inspection

After the gear is completed, we will provide you with a report on raw materials, hardness, and size information.

-Packaging

The choice of our packaging method is based on the characteristics of the product and the requirements of the customer.
