      Small specification universal coupling

      TIME:2017-08-21    AUTHOR:admin

      Name: small specification universal coupling
      Description: a small specification universal coupling advantage of the characteristics of its organization, make the two axis is not in the same axis, the presence of axis Angle can be achieved by coupling of two continuous rotary shaft, and transmission torque and reliably.
      Label: SWP F type (large expansion single) universal coupler SWP E type (with telescopic flanged flanged long) cross shaft universal couplings SWC WH type (no telescopic weld-type) universal couplings
      Product details:
      Small specification universal coupling advantage of the characteristics of its organization, make the two axis is not in the same axis, the presence of axis Angle can realize the connection of two continuous rotary shaft, and transmission torque and reliably.
      The maximum characteristic of universal coupling is that its structure has a large Angle compensation ability, compact structure and high transmission efficiency. Different structural type universal coupling two axis Angle different, generally between 5 ° to 45 °.
      Small specification universal coupling has a variety of structural type, such as: the cross shaft, ball cage, ball fork, lug type, ball pin type, knuckle ball, the ball hinge plunger type, three pin type, fork rod type, three ball pin type, hinge rod type, etc.; The most commonly used cross - axis type is the ball cage type. In practical application, according to the transmission torque size, it is divided into heavy, medium, light and small.
      Small specification universal coupling purpose
      To connect two shafts in different agencies (active and driven shafts) to rotate the mechanical parts to deliver torque. In the power transmission of high speed overload, some couplings have the function of buffering, damping and improving the dynamic performance of shafting. The coupling consists of two parts, which are connected with the driving shaft and the driven shaft. Generally, the power machine is connected to the working machine by means of the coupling.
      Small specification universal couplings are used for large universal couplings, and bearings are the vulnerable parts of the cross-shaft universal coupling. The main difference of several large cross-axial universal couplings is the change of the bearing and the cross head, which forms different structures. To ensure the synchronization of principal and driven shaft, adopt dual form, in the actual application of the double connection way is welded or bolted flange plate connector, the length in the middle of the changes can take many forms.
