Q: What are the main types of spline shaft profiles available?
A: There are three primary spline shaft profiles: involute (most common for high torque applications), straight-sided (simpler to manufacture), and serrated (used when axial movement is required). Involute splines provide the best load distribution and are self-centering, making them ideal for precision applications. The choice depends on your specific torque requirements, manufacturing capabilities, and operational conditions.
Our spline shafts undergo a rigorous manufacturing process to ensure dimensional accuracy and mechanical properties:
Q: How do I determine the correct spline shaft size for my application?
A: Determining spline shaft size involves calculating torque requirements, considering space constraints, and evaluating service conditions. Key factors include: torque capacity (based on material and heat treatment), number of teeth (affects load distribution), pressure angle (typically 30° or 37.5°), and fit class (determines clearance between mating parts). Our engineering team can assist with proper spline selection based on your specific application parameters.
All our spline shafts undergo comprehensive testing to ensure they meet international standards:
We offer complete customization for spline shafts to meet your exact requirements:
Q: What maintenance is required for spline shafts?
A: Spline shafts generally require minimal maintenance, but proper care extends service life. Regular lubrication with appropriate grease prevents wear and corrosion in sliding applications. Inspect periodically for: tooth wear patterns (indicating misalignment), surface pitting (inadequate lubrication), and corrosion (especially in harsh environments). For fixed connections, check torque values of retaining fasteners during scheduled maintenance. Always use proper handling procedures to avoid damaging the spline teeth during installation or removal.
