In a geared transmission, the driving gear must engage with its mating gear according to a defined tooth geometry and mounting position. Our Drive Gear Shaft is designed for auxiliary transmission applications where the shaft and gear features need to match the gearbox arrangement.

This design uses 20CrMnTi steel with carburizing and quenching. The specified surface hardness is HRC58–62, and the gear accuracy requirement is DIN Grade 7. These criteria give equipment manufacturers and replacement-part buyers a reference for confirming gear engagement and shaft mounting dimensions.

Agricultural machinery gearboxes
Replacement driving gear components

OEM/ODM Customization

We manufacture according to technical drawings or physical samples. Custom details may include shaft dimensions, gear geometry, mounting features, material, heat treatment, and gear accuracy. The mating gear and gearbox layout should be confirmed before production.

Quality Control

Sampled components receive dimensional inspections during production. Full inspection can be arranged for selected parts, and third-party inspection is accepted. Critical gear and mounting dimensions should be specified in the approved drawing.
