Product Description

 

1. Product Overview

A spline shaft is a mechanical transmission component that uses longitudinal keyways on the shaft surface to engage with matching hub keyways, enabling torque transmission and synchronous rotation. Some types also support axial sliding (e.g., gearbox gears), featuring high load capacity, good centering, and guidance.

2. Core Parameters & Classification

1. Main Types & Features

Type	Tooth Shape	Features	Application Scenarios
Straight Spline Shaft	Rectangular teeth	Multi-tooth load-bearing, low stress concentration, easy to machine, high precision	Automotive, machine tools, agricultural machinery
Involute Spline Shaft	Involute teeth	Automatic centering, uniform tooth stress, high strength, long service life	Heavy-duty equipment, aerospace, large machinery

2. Basic Parameters

Item	Parameter Range	Note
Material	40Cr, stainless steel, aluminum alloy, titanium alloy, etc.	Commonly used: 40Cr (quenched to HRC 45-50)
Number of Teeth	6-40 teeth (common: 6, 12, 16, 25 teeth)	Light/medium series standards
Centering Method	OD centering, ID centering, tooth side centering	Straight splines often use OD centering
Module	1-10 mm	Common for involute splines

3. Processing Technology Comparison

Process	Equipment	Precision	Efficiency	Application Scenarios
Hobbing	Spline hob + milling/gear hobbing machine	High	High	Mass production (internal/external splines)
Milling	Universal milling machine + forming cutter	Medium-low	Low	Prototypes/small batches (rough machining)
Grinding	Spline grinding machine + forming wheel	Highest	Medium	Hardened splines/high-precision ID centering
Cold Forming	Special cold heading machine	Medium-high	High	High material utilization (plastic deformation)

4. Typical Product Specifications
