Product Description
1. Product Overview
A spline shaft is a vital mechanical transmission component featuring longitudinal keyways on its surface, designed to perfectly engage with matching hub keyways, enabling flawless torque transmission and precise synchronous rotation. Certain versions also facilitate smooth axial sliding (such as those in gearbox gears), boasting exceptional high load capacity, excellent centering precision, and remarkable guidance capabilities.
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
1. Straight Spline Shaft (Examples)
| Model | OD (mm) | ID (mm) | Teeth | Length (mm) | Application |
|---|---|---|---|---|---|
| 6-25-100 | 25 | 20 | 6 | 100 | Automotive drive shaft |
| 12-35-200 | 35 | 30 | 12 | 200 | Machine tool gearbox |
2. Involute Spline Shaft (Examples)
| Module | Pressure Angle | Teeth | Precision Grade | Application Scenarios |
|---|---|---|---|---|
| 2 | 30° | 24 | IT6-IT7 | Aircraft engine transmission |
5. Application Fields
- Automotive: Perfect for gearbox shafts, steering systems, and half-shafts
- Machine Tools: Ideal for lead screws and dividing head shafts
- Aerospace: Engine drive shafts and landing gear components
- Industrial Equipment: Suitable for reducers, conveyors, and hydraulic systems
- Special Scenarios: Telescopic spline shafts, such as those in off-road vehicle drive systems
6. Quality & Testing
- Heat Treatment: Quenching and tempering techniques achieve surface hardness of HRC 45-50, while maintaining core toughness
- Testing Items: Comprehensive checks for tooth profile accuracy, concentricity, surface roughness, and torque capacity
- Standards: Fully compliant with GB/T 1144 for straight splines and GB/T 3478 for involute splines
7. Customization Services
Fully support non-standard customization in:
- Materials: Including stainless steel, aluminum alloy, among others
- Dimensions: Options for extra-long shafts (up to 1800 mm), and micro shafts (down to 10 mm)
- Surface Treatment: Featuring chrome plating, zinc plating, and black oxide options
Note: The specified parameters serve as general guidelines. Tailored specifications are available to meet specific equipment requirements.
