1.  Introduction  

1. The coupling of transmission motor for construction hoist are designed specifically for precision applications, such as encoders and tachometers that use delicate components. The small bearings on these components make low radial forces essential to longevity and continued high performance.

2. These flexible couplings feature larger body size and stronger beams to provide high torque capacity and very low windup, while not sacrificing misalignment capabilities. The demanding nature of reversing servo applications make the performance benefits delivered by the  couplings vital to maintaining the accuracy, repeatability and reliability of the system.

3. The couplings each have two sets of spiral slots, a feature that provides superior parallel misalignment capabilities compared to the single beam coupling. Angular misalignment, axial motion and any combination of all three types of misalignment are also easily accommodated by this flexible coupling. Beam couplings have the additional benefit of a balanced design for reduced vibration and higher RPM capabilities.

4. The helical couplings should be used in applications in which misalignment exists between the two shafts being coupled. The helical couplings are ideal for light duty power transmission applications such as coupling a servo motor to a lead screw in a motion control system.

 

2. Features 

1. Die forging work blank, no sand holes
2. Dynamic balance accuracy is within 2g
3. The inner-hole process has a high precision, the selection of coupling should cooperate with reducer.
