Planetary gearbox - quenching process treatment of marine gearbox
Marine reducers are generally arranged after rough production, before cutting, or after rough machining and before semi precision machining.
The purpose of quenching planetary reducers is to refine grain size, improve microstructure, and enhance cutting performance. Therefore, the following editor will introduce in detail the quenching process of marine reducers.
Planetary reducer - the method of quenching and high-temperature tempering is quenching and tempering. Quenching and tempering can greatly adjust the performance and material of steel, and its strength, plasticity, and toughness are all good. Planetary reducer - has good comprehensive mechanical properties.
Right angle reducer - tempered martensite is obtained after quenching and tempering treatment. Cr can increase the hardenability of steel, improve its strength and tempering stability.
Right angle reducer - for quenched and tempered workpieces with excellent mechanical properties and large or important cross-sectional dimensions, 42CrMo steel should be used for quenching and oil cooling. 42CrMo steel has good hardenability and can be hardened by cooling in oil, and the deformation and cracking tendency of the workpiece is small.
Mixer reducer - After quenching and tempering, the parts have good comprehensive mechanical properties, but do not meet the process requirements. Therefore, the mixer reducer needs to undergo induction surface quenching to achieve the required mechanical properties. After induction heating quenching, the hardness is relatively high, and it is not suitable for other cutting processes except grinding.
Right angle planetary integrated machine - Therefore, the process position is generally arranged after semi precision machining, before grinding, and after quenching, the surface obtains high hardness and high wear resistance.
Right angle planetary integrated machine - while the core still maintains good comprehensive mechanical properties, in order to reduce the quenching stress of surface quenching, maintain high hardness and wear resistance, it should be quenched at low temperature after quenching.
