Heat treatment and function of coupling

　　The heat treatment of the coupling is an operation process that puts the metal or alloy in the solid range, through the organic cooperation of family, heat preservation, and cooling, so that the metal or alloy changes the internal structure to obtain the required performance. The heat treatment of the coupling is a modern machine. It is an indispensable part in industry and metallurgical industry to improve product quality and extend the service life of machine parts.

　　The heat treatment of the coupling is divided into preliminary heat treatment (or pre-heat treatment) and final heat treatment (or post heat treatment). In modern industrial production, the heat treatment of the coupling has become an important process specification.This is because of the excellent mechanical properties of steel and certain alloys—high hardness, strength, elasticity, and wear resistance. In addition to obtaining the required chemical composition during smelting, it must be obtained through heat treatment afterwards. Therefore, in order to achieve technical The above requirement is that we need to heat-treat the coupling in the process of producing the coupling.

　　The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.Generally, power machines are mostly connected with working machines by means of couplings, which are commonly used coupling parts for shaft transmission of mechanical products.Couplings belong to the category of general mechanical parts and are used to connect two shafts (active shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque.In high-speed and heavy-load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.

　　In the late 20th century, coupling products at home and abroad have developed rapidly. In product design, how to choose a coupling that can meet the requirements of the machine from a variety of couplings with different performances? For most designers, It is always a troublesome problem.Commonly used couplings include diaphragm couplings, drum gear couplings, universal couplings, couplings, elastic couplings and serpentine spring couplings. The coupling acts to connect two shafts to make two shafts. Rotate together to transmit motion and torque, which can realize the coupling and separation between the shaft and the shaft, so as to realize the transmission and interruption of power.

　　Similarities: connecting two shafts, transmitting motion and torque

　　Differences: The two shafts connected by the coupling can only be separated after being disassembled after parking. The two shafts connected by the clutch can be easily separated and joined during machine operation.

　　Due to manufacturing and installation errors, elastic deformation and temperature difference deformation of parts under load, the two axes connected by the coupling will inevitably have a relative offset.
