Factors needed for purchasing plum blossom coupling
Date：2021-03-03 Click： 772
1. Purchasing experience of quincunx coupling: mainly for the basin friends who enter the industry, the data and dimensions that need to be provided to the manufacturer for purchasing coupling are as follows
①Shaft hole diameter, shaft hole length or shaft hole diameter, total length of coupling
②Coupling speed torque requirements, shaft hole diameter, shaft hole length.
③ It can be processed according to the drawing.
2、 There are two types of quincunx elastic couplings as follows
Ml ordinary quincunx elastic coupling.
MlZ single flange quincunx elastic coupling.
MLS double flange quincunx elastic coupling.
MLL type quincunx elastic coupling with brake wheel.
The above are the main commonly used types of quincunx elastic coupling.
3、 There are two kinds of common plum coupling
One is clamping fixed quincunx coupling, which is made of aluminum alloy
One is the key type plum blossom coupling, which is mostly made of 45 steel. According to the style of elastomer, it can be divided into star elastic coupling and plum elastic coupling.
4、 Plum blossom coupling is one of the elastic couplings, which has the function of elastic buffer. This paper introduces the function and effect of plum blossom elastic coupling. Plum blossom coupling is a common coupling, also known as elastic nail coupling, which is composed of two metal nail plates and an elastic body. The two metal claw discs are generally 45 steel, but aluminum alloy is also used when load sensitivity is required. The elastomer is made of high elastic polyurethane material, which has the function of high temperature resistance and shock absorption. The service life of coupling is elastic life. Elasticity is compression, obviously tension. The service life of general elastomer is 10 years. Elasticity has the function of buffering and damping, and is mostly used for strong vibration. The performance limit temperature of elastomer determines the service temperature of coupling, generally from - 35 ℃ to + 80 ℃.
