What is the spline sleeve?
Spline sleeve is a mechanical transmission part with an internal spline structure. It is usually cylindrical. Its inner wall is processed with multiple key teeth and keyways evenly distributed along the circumferential direction. It can be matched with the external spline of the spline shaft. It is mainly used to transmit torque and motion in mechanical devices. It can achieve high-precision centering and relative motion. It has the characteristics of strong load-bearing capacity and good guidance. It is widely used in various mechanical transmission systems.
Common materials
It belongs to medium carbon steel, has certain strength, hardness and toughness, and has good comprehensive mechanical properties. After appropriate heat treatment and surface treatment, it can meet the use requirements of spline sleeves under general working conditions. The cost is relatively low and it is widely used.
It is an alloy structural steel with higher strength, hardness and wear resistance than 45 steel, and has good hardenability. After heat treatment such as quenching and tempering and surface quenching, it can be used for spline sleeves with large loads and high speeds.
It is a carburizing steel with good carburizing performance and core strength. After carburizing and quenching, the surface layer with high hardness and high wear resistance can be obtained, while the core maintains good toughness. It is suitable for spline sleeves with high speed, heavy load and large impact load.
Processing technology
Cutting: According to the size and material requirements of the spline sleeve, select the appropriate raw materials, and use sawing machines, cutting machines and other equipment to cut the raw materials into the required billet size.
Forging: Forging the billet, by applying pressure to make it plastically deformed, improve the internal structure of the metal, improve the strength and toughness of the material, and initially form the shape of the spline sleeve.
Rough machining: including turning the outer circle, inner hole, end face, etc., leaving a certain machining allowance for subsequent finishing, and the tooth profile of the spline can also be machined by milling or slotting.
Finishing: The outer circle, inner hole and spline tooth profile of the sleeve are precisely machined by grinding and other methods to achieve higher dimensional accuracy, shape accuracy and surface roughness requirements.
Inspection: Use measuring tools such as calipers, micrometers, three-coordinate measuring instruments, etc. to measure the dimensional accuracy of the spline sleeve, use hardness testers to test the hardness of the materials, and use flaw detection equipment to inspect the sleeve to ensure that the product quality meets the design requirements.
Heat treatment & Surface treatment
Heat treatment
Quenching: Heat the spline sleeve to above the critical temperature, keep it warm for a certain period of time, and then cool it rapidly to obtain martensitic structure and improve the hardness and strength of the sleeve. For 45 steel and 40Cr steel, oil quenching or water quenching is often used; for 20CrMnTi steel, carburizing quenching is generally used.
Tempering: Tempering is an important process to eliminate quenching stress, stabilize the structure and improve toughness. According to different use requirements, low temperature tempering, medium temperature tempering or high temperature tempering can be used.
Surface treatment
Nitriding treatment: Nitrogen atoms are infiltrated into the surface of the spline sleeve to form a nitrided layer with high hardness, good wear resistance and strong corrosion resistance, which can significantly improve the surface hardness, wear resistance, bite resistance and corrosion resistance of the sleeve, and can withstand higher loads and harsher working environments.
Hard chrome plating: A layer of hard chrome is plated on the surface of the spline sleeve to improve the surface hardness, wear resistance and finish of the sleeve, reduce the friction coefficient, and have good corrosion resistance, which can effectively improve the service life and working performance of the sleeve.
Phosphating treatment: A layer of phosphate conversion film is formed on the surface of the sleeve, which has good lubricity and corrosion resistance, can reduce friction and wear, improve the assembly performance and rust resistance of the spline sleeve, and is often used as the bottom layer for subsequent treatments such as painting and oil immersion to further improve the surface protection effect.
