The three-jaw type coupling for pump is a kind of water pump coupling. The middle slider is made of cloth bakelite or polyurethane. It is light in weight, simple in structure, convenient to install and low in price. It is often used in low power applications. The two-axis connection is not large in torque, high in speed, and has no sharp impact. The nylon slider transmits less torque, but it is more suitable for high speed operation and does not require lubrication. The standard code of the pump industry is Bl104.
The pump three-jaw coupling is a pin made of several non-metallic materials, placed in the matching hole between the two coupling halves and the inner surface of the outer ring, and the torque is transmitted through the pin to realize the two halves. Coupling, the coupling has the following characteristics: three-prong coupling for pump
(1) The transmission torque is large. When the same torque is used, the diameter of the rotation is mostly smaller than that of the toothed coupling, and the volume is small and the quality is light, which can partially replace the gear coupling.
(2) Compared with the toothed coupling, the structure is simple, the components are few, and the manufacturing is convenient, and the gear processing machine is not needed.
The middle slider of the 1 claw type coupling is made of cloth bakelite or nylon;
2 small volume, light weight, simple structure, convenient installation, low price, often used in low power applications;
3Inertial force is small, suitable for two-axis connection with low torque, high speed and no sharp impact. The nylon slider transmits less torque, but is more suitable for high speed operation without lubrication.
4 allow relative radial displacement (0.01d + 0.25) mm, d is the shaft diameter (mm); allowable relative angular displacement 0 degrees 40 minutes; the additional radial force of the coupling is (0.1 ~ 0.3) P;
5 The standard code of the pump industry is Bl104, the maximum allowable torque is 850N·m, and the maximum shaft diameter is 50mm.
