The characteristics of the star-shaped plum elastic coupling

The different hardness and temperature endurance of the quincunx spacer of elastic material in the quincunx elastic coupling allow customers to choose the right material to meet the performance standards of the actual application.The zero-clearance claw coupling is composed of two metal sleeves (usually made of aluminum alloy, stainless steel can also be provided) and a plum blossom elastic spacer.The plum blossom elastic spacer has multiple leaf branches. Like a slider coupling, it also squeezes the plum blossom elastic spacer and the sleeves on both sides to match it, thereby achieving its zero clearance performance.

Vibration analysis is one of the techniques for predicting coupling misalignment. It can judge the gradual change trend of the equipment state, but when judging whether a device is in a misalignment state, it needs to have a lot of past data and examples for reference, and there are differences. The problem is the bearing, lubricating oil, coupling, or the fixed connection, so there are some limitations.Infrared photography technology can distinguish overheated parts such as bearings, motor housings, couplings, etc. when the equipment is in poor condition, and determine the alignment error of the coupling, combined with other prediction technologies such as vibration analysis , The effect will be good.

The traditional straight-jaw plum blossom coupling is not suitable for use in high-precision servo transmission applications.The zero-backlash claw type plum blossom coupling is evolved on the basis of the straight claw type, but the difference is that its design can be suitable for the application of the servo system, and is often used to connect servo motors, stepping motors and ball screws.The curved surface is to reduce the deformation of the elastic plum spacer and limit the influence of centripetal force on it during high-speed operation.The zero-clearance claw coupling is composed of two metal sleeves (usually made of aluminum alloy, stainless steel can also be provided) and a plum blossom elastic spacer.The plum blossom elastic spacer has multiple leaf branches. Like a slider coupling, it also squeezes the plum blossom elastic spacer and the sleeves on both sides to match it, thereby achieving its zero clearance performance.
