The small resistance torque of the coupling affects its operation

When a car is turning at medium speed, the differential speed of the left and right wheels is not large, and the resistance torque generated by the viscous coupling is small, which has little impact on the handling of the car. The differential ability of the differential is also very small, so the parallel connection of the two does not affect the normal operation of the differential, and the coupling does not affect the function of the differential to prevent power circulation. Excessive differential of the gearbox will affect the steering flexibility of the car.

If the bolt cannot be removed yet, heating method can be used, and the heating temperature is generally controlled below 200 degrees Celsius. By heating, the distance between the nut and the bolt increases, and rust is also easy to fall off, making bolt disassembly easier. Replace the bolts with new ones during assembly, which have the same specifications as the original ones. Use the new bolts for high-speed equipment couplings to ensure that the weight of the new bolts is the same as that of the connecting bolts on the same set of flanges.

The workpiece is cylindrical bulging to meet the requirements of interference fit assembly. The current heater is controlled by a microcomputer, and the heating temperature and time of the bearing can be set and displayed. The coupling heater is mainly used to heat various types of metal parts such as bearings, gears, coupling joints, railway locomotive wheel centers, and wheel rims; The coupling device has a high requirement for the two axes to be neutral. When there is relative displacement between the two axes, it will cause additional loads inside the machine, which will worsen the working condition.

The transmitted large torque should be less than the allowable torque value, and the determination of large torque should consider the acceleration and deceleration torque and overload torque required for machine braking. Under the same conditions, try to choose couplings with simple maintenance; When working at high temperatures, couplings with non-metallic components are not optional.
