Gear Shafts

Founded in 1988, Jinjiang Feida Machinery Co., Ltd. Covers an area of 45, 000 square meters and has over 30 years of expertise in the R&D and manufacturing of gear shafts, which feature compact structure,high transmission reliability,high rigidity, and high manufacturing requirements. The primary function of the product is to transmit power and mechanical motion.

Main Structure

Gear Section:The core part of a gear shaft;meshes with other gears to transmit power and motion.
Journal:The section of the shaft that usually fits with a bearing and supports the rotation of the gear shaft;typically have relatively high requirements for dimensional accuracy, roundness, surface roughness, and wear resistance.
Shaft Shoulder:Used to provide axial positioning for bearings, gears, and other components. It can also help transmit certain axial loads.
Shaft Body:The main section connecting the gear section, journals, and other structural features.Its primary functions are to transmit torque and withstand bending loads generated during operation.
Shaft End:Used to connect the gear shaft to couplings, other gears, sprockets, or other transmission components.Depending on the application, the shaft end may be designed as a cylindrical, tapered, threaded, or splined shaft end.

Key Parameters

A gear shaft generally refers to a shaft with gear teeth machined directly onto the shaft body.Its key parameters include:

● Module (m) : Determines the size of the gear teeth.
● Number of Teeth (z) : Determines the gear ratio and basic gear dimensions.
● Pitch Diameter (d) : An important reference dimension for gear design.
● Face Width (b) : Affects the load-carrying capacity of the gear.
● Shaft Diameter (dₛ) : Determines the strength and load-bearing capacity of the shaft.
● Rotational Speed (n) : Affects transmission performance and dynamic loads.
● Transmitted Power (P) and Torque (T) : Key load parameters used to determine the strength and dimensions of the gear shaft.
● Material and Heat Treatment : Affect the strength, wear resistance, fatigue resistance, and service life of the gear shaft.

Manufacturing Process & Quality Control

Our typical production process can be summarized as follows:
Blank preparation → Forging → Turning → Gear hobbing → Heat treatment → Gear grinding → Grinding → Inspection → Packaging

Feida conducts production activities in compliance with ISO 9001:2015. Quality control is implemented throughout the entire production process, covering IQC, IPQC, FQC and OQC, to ensure product quality.Test include dimensions, hardness, tooth profile, tooth alignment, and surface quality.
