The reducer has a wide range of applications, which is inseparable from its excellent performance. We know that usually in order for the equipment to function better, the matching equipment is usually selected, and the coupling is often used with this equipment There are many types of couplings, how should we choose? Let's take a look at its selection method together.
1. According to the load transmitted by the reducer, 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 x, Y Directional displacement and skew 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, couplings with high balance accuracy, such as diaphragm couplings, should be used instead of eccentricity. The slider coupling.
Thirdly, when selecting couplings for severe impact loads or transmission systems that require the elimination of shaft torsional vibrations, high elasticity, good shock absorption and excellent inter-axis offset compensation performance can be selected, which is suitable for impact occasions. Tyre couplings, etc.
3. The appropriate coupling can be selected according to the manufacture, installation, maintenance and cost of the coupling. Under the premise of satisfying the performance of the reducer, a coupling that is easy to assemble and disassemble, simple to maintain, and low in 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, high-rigidity drive shafts. General non-metallic 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 small and medium-sized Power transmission system.
