SWP D type (no telescopic short type) cross shaft universalCouplingThe selection mainly considers the speed of the required transmission shaft, the size of the load, the installation accuracy of the two connected components, the stability of rotation, the grid, etc., refer to the characteristics of various couplings, and choose a suitable coupling器型。 Type.
SWP D type (non-retractable short type) cross-shaft universal coupling can consider the following points when selecting:
1. Due to reasons such as manufacturing, installation, load deformation and temperature change, it is difficult to maintain strict alignment of the two shafts after installation and adjustment.There is a certain degree of displacement in the x and Y directions and the deflection angle CI.When the radial displacement is large, you can choose a slider coupling, and when the angular displacement is large or the connection of two intersecting shafts, you can choose a universal coupling.When the two shafts produce a large additional relative displacement during the working process, a flexible coupling should be used.
2. The working speed of SWP D type (non-retractable short type) cross-shaft universal coupling and the amount of centrifugal force caused.For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be used instead of eccentric slider couplings.
3. The size and nature of the torque to be transmitted and the requirements for the function of damping vibration.For example, for high-power heavy-duty transmission, you can chooseGear coupling.For severe impact loads or transmissions that require the elimination of shaft torsional vibration, tire couplings can be used.
