   Plum ElasticityCouplingThe different hardness and temperature endurance of the plum spacers of elastic materials in China allow customers to choose suitable materials to meet the performance standards of actual applications.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 ensure 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 piece of equipment 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 certain 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, and combine it with other prediction technologies such as vibration analysis. , Its effect will be better.
  Traditional straight claw typePlum couplingIt is not suitable for use in high-degree servo drive 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 ensure its zero clearance performance.
