Couplings (GR) Manufacturing Process:Die Casting

Product structure: It is composed of two claw gears of shaft sleeves and a plum-shaped natural polyurethane elastomer. Shaft kit material: 45 Elastomer material: 98 ShA red The structure is small in size, light in weight, and high in transmission torque, which effectively improves the running quality and stability of the machine. Effectively reduce the vibration and impact generated during the operation. When the shaft is installed, the drum-shaped tooth of the elastic body can effectively correct the axial,radial, and angular installation deviations to avoid the concentrated force. Star lock type coupling Forged from 45 gauge steel 20 years of professional manufacturing of couplings, one-to-one service by engineers.

GR star-shaped elastic coupling The polyurethane elastomer is limited by the convex claw block. This coupling uses engineering plastics as the elastic element. It is suitable for connecting two coaxial transmission shafts. It can compensate for the relative offset of the two shafts. , Cushioning, shock absorption, wear resistance, suitable for common occasions. Transmission torque 20-35000.N.M. Working temperature -35℃~+80℃, and interchangeable with German ROTEX coupling. The elastic element in the star-shaped elastic coupling is engineering plastic. Because the engineering plastic has good elasticity, cushioning, shock absorption and wear resistance, it can well compensate for various displacements between the two transmission shafts. Backlash-free connections under prestress for spindle drives, lift platforms and machine tools, etc. Star couplings are sometimes mistaken for plum couplings. Their appearance after installation is almost similar, but under the same model, the star coupling bears more torque. Compared with the plum coupling, its inner hole and The shape can be made smaller. In addition to dust and oil storage, insufficient thinning may cause interference, and excessive thinning will weaken the strength of the teeth and cause large backlash. The contact conditions of the external teeth are improved, which avoids the disadvantages of the edge extrusion and stress concentration of the straight teeth under the condition of angular displacement. At the same time, the friction and wear conditions of the tooth surface are improved, the noise is reduced, and the maintenance period is long. When designing the overall structure of the star-shaped elastic coupling, full attention should be paid to the lubrication and dust prevention between the tooth surface and the roller, as well as safety protection. If the chain is broken, it may cause personal accident. The radius of curvature of the bulge curve is proportional to the unilateral thinning of the inner teeth, that is, it is related to the meshing clearance of the teeth, which makes the assembly and disassembly of the inner and outer teeth very convenient. The large concave surface of the claws makes the surface pressure on the involute teeth very small, and even if the teeth are overloaded, the teeth will not be worn or deformed. Axial plug-in assembly for easy blind assembly and time saving; Small size, small moment of inertia, maintenance-free; Easy visual inspection.
