How to choose the coupling on the reducer?

The normal operation of the reducer is inseparableCouplingRole, so everyone knows how to choose a reducerCouplingWhat factors should we consider? Then follow the editor to understand it:

  1. According to the size of the transferred load, the speed of the shaft, due to manufacturing, installation, load deformation and temperature changes, it is difficult to maintain strict alignment of the two shafts after installation and adjustment, and there is a certain degree of displacement in the x and Y directions. And the deflection angle.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. Choose the coupling type according to the working speed of the coupling and the amount of centrifugal force caused. For high-speed drive shafts, a coupling with high balance precision should be selected, such asDiaphragm couplingEtc., it is not appropriate to use eccentric slider couplings.

  3. When selecting couplings for severe impact loads or transmission systems that require the elimination of shaft torsional vibrations, high elasticity and good shock absorption and excellent inter-axis offset compensation performance can be selected, suitable for impact occasions Tyre couplings, etc.

  4. The appropriate coupling can be selected according to the manufacture, installation, maintenance and cost of the coupling.Under the premise of satisfying the performance, couplings with convenient assembly and disassembly, simple maintenance and low cost should be selected.For example, the rigid coupling is not only simple in structure, but also easy to assemble and disassemble, and can be used for low-speed, rigid drive shafts.General non-metal elastic element couplings, such as elastic sleeve pin couplings, elastic pin couplings, plum-shaped elastic couplings, etc., because of their good comprehensive capabilities, they are widely used in general medium and small Power transmission system.
