A Torque Coupling with Soft Start Function

Abstract

The patent of the present invention discloses a torque limiting coupling with soft start function, which includes a rotor, the inner rotor is sleeved on the driving end, and the outer ring is connected to the load end; the inner rotor is provided with several first transmission devices and several A second transmission device; the first transmission device is evenly distributed along the outer circumference of the inner rotor, and a first thrust rod is arranged on the inner side of the outer ring opposite to the first transmission device; the second transmission device includes a thrust end and a counterweight end, and the thrust end is located inside at the outer circumference of the rotor, and several thrust ends are evenly distributed along the outer circumference of the inner rotor, and arranged crosswise with the first transmission device, and second thrust rods are provided at the end of the inner side of the outer ring opposite to the second transmission device; the present invention adopts The transmission device set on the inner rotor transmits the driving end torque to the load end. When the motor shaft rotates, the torque at the load end can be increased smoothly without rigid impact; after the load end enters normal operation, it can transmit a large enough torque to realize the protection of the equipment and mechanism of the transmission chain.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, and relates to a moment-limiting shaft coupling with a soft start function. Background technique [0002] Coupling is a transmission rotating part that connects two shafts or flanges and shafts or flanges and flanges. It is a device that rotates together without disengagement during the process of transmitting motion and power (torque), and does not change during the transmission process. The direction of rotation and the magnitude of the torque. [0003] In the mechanical transmission system, due to the large starting current of the motor during the start-up phase, the duration of the entire start-up process should not be too long, otherwise the motor will heat up and burn out. Therefore, the motor is required to increase from zero speed to rated speed (for example: 1500RPM) in a short time (for example: 10-25 seconds), and at the same time drive the load end to increase from zero speed...

AI Technical Summary

Problems solved by technology

If the coupling is rigidly connected when starting, it will have a large impact on the load end, which will cause too much impact during start-up and damage the related equipment on the transmission chain; or it will not be able to drive the load end to start smoothly, especially when the load Start with a load on the end; or the start-up time is too long so that the motor heats up and burns out for a long time

[0004] After the load end enters normal operation, if the load end is overloaded, blocked, external impact, etc., the load on the load end will rise sharply, which will cause damage to the equipment and mechanisms in the transmission chain.
