The three-jaw coupling for pumps uses several pins made of non-metallic materials, which are placed in the mating holes between the two halves of the coupling and the inner surface of the outer ring, and the two halves of the coupling are transmitted through the pins. The coupling has the following characteristics: (1) The transmission torque is large, the rotating diameter is mostly smaller than the gear coupling at the same torque, the volume is small, and the weight is light. It can partially replace the gear coupling . (2) Compared with gear couplings, it has simple structure, fewer components, and is more convenient to manufacture. It does not require gear processing machine tools.
①The middle sliding block of the claw coupling is made of cloth bakelite or nylon;
②Small size, light weight, simple structure, convenient installation, low price, often used in small power occasions;
③Small inertia force, suitable for two-axis connection with low torque, high speed and no sharp impact
Pick up.Nylon sliders transmit less torque, but are more suitable for high-speed operation and do not need lubrication;
⑤The standard code of the water pump industry is Bl104, the maximum allowable torque is 850N·m, and the maximum shaft diameter is 50mm
