Lubricating oil film has great influence on the performance and service life of plum type elastic coupling. Without sufficient oil lubrication and viscosity, oil film can not be formed, which will lead to direct contact between metal components, which will damage the wear and abrasion of the coupling transmission parts, so that the shaft and bearing accessories load increase, which is harmful to the coupling. Therefore, the use of lubricating oil coupling should be regularly checked, timely replacement of damaged seals and aging lubricating oil.

Plum type elastic coupling in the process of use need to observe the principle:

First, in general, when the sensor is installed, the coupling selected is rigid connection, large vibration, small concentricity and 0.2mm large 0.05mm, it is recommended to use elastic connection. Rigid connections outside this range can be selected.

Two, torque sensor in use, it should be installed between the power source and load of the two groups of coupling, power load and load equipment fixed reliable avoid vibration, otherwise it will lead to the instrument can not work normally.

3. When standard torque instrument is used, no matter how it is installed, the axial force and bending moment to be borne by the coupling should be avoided as far as possible, which will directly lead to the damage of the instrument and make it impossible to use.

Plum type elastic coupling is suitable for connecting two coaxial lines of a transmission shafting, and in the process of work has the compensation of two axes relative offset, cushioning, shock absorption, wear resistance, suitable for common occasions. The plum type elastic coupling consists of two halves connected with the drive shaft and the driven shaft respectively. The general engine is connected with the working machine mostly by means of coupling, which is a common connection part of the mechanical product shafting transmission.
