Performance of Contact Surface of Grid Coupling
2023-08-24 15:00Install and calibrate the grid coupling to control reasonable deviation. The grid coupling allows for significant installation deviation, but during the installation process, the gap and angular deviation between the two hubs should also be corrected within the specified values. During the installation process, measure the gap between two hubs every 90 °, and the difference in size values should not exceed 0.38mm. and the temperature of the lubricating grease injection point should be ≥ 150 ℃. Lithium based lubricating grease can resist centrifugal force.
The grid coupling has separation stability, no impurities, and does not corrode carbon steel and nitrile rubber; Filling in sufficient lubricating grease is crucial for the coupling. Use a dry oil gun to inject lubricating grease until an excess of grease overflows from the hole. Suggest checking every three months. The grid coupling is a kind of metal elastic coupling that embeds the grid axially into the teeth of two hubs, achieving the connection between the motor and the working machine. The grid coupling has a simple structure, convenient installation and disassembly, and a large installation deviation.
Due to the special performance of grids, resonance between the motor and the working machine is largely avoided, and their service life is much longer than that of non-metallic elastic component couplings. The teeth surface is curved, and the size of the contact surface varies with the magnitude of the transmitted torque, ensuring safe and reliable operation. The grid coupling is mainly used for crushing machines, reciprocating motion of cranks, reducers, metallurgy, mining, lifting machinery, etc.
The grid as an elastic component, has strong elasticity and greatly improves the transmission torque of the grid coupling. It is widely used in heavy machinery and general machinery, with a long service life. The two hubs of the grid coupling allow relative radial displacement of 0.5-3mm, axial displacement of 4-20mm, and angular displacement of 1 ° 15 '. The grid coupling has high transmission efficiency, safe starting, and a transmission efficiency of up to 99.47%. Its short-term overload capacity is twice the rated torque; The grid coupling has good vibration reduction effect and avoids resonance when used.
