SU100693A1 - Torque limit clutch - Google Patents

Description

The subject of the invention is a torque limiting clutch for connecting coaxial shafts, consisting of a leading coupling half and a spring-loaded driven coupling half aligned to it, kinematically interconnected by an intermediate yoke carrying carrier elements.

A distinctive feature of the design of the described coupling is that the weft holder is provided with radials located by the drive rollers and is spring-loaded towards the leading zero coupling, on the end surface of which, besides the hollows, there are deep grooves designed to fully immerse the rollers when the yoke turns overload clutch.

For the subsequent engagement of the coupling, a pivoting spring-loaded servo clamp is mounted on the coupling half and rotated relative to the coupling half by means of a brake belt and acting on axial followers squeezing the drive rollers out of the slots of the coupling half coupling.

Such a clutch device makes it possible to completely disconnect the drive shaft from the slave when the torque limit is exceeded and to eliminate overheating and wear of the clutch elements.

FIG. 1 shows a side view of the coupling; in fig. 2 is a section through AOB in FIG. one; in fig. 3 is a view along arrow B in FIG. 2; in fig. 4 is a view along arrow G in FIG. 2; in fig. 5 shows a section along the line B in FIG. four.

The coupling consists of a half-coupling fixed on the drive shaft and coupling half coaxially located on the driven shaft, axially movable and spring-loaded spring 3. The torque is transmitted through the driven radial rollers 4 mounted on the pins (intermediate, freely fitted on the drive shaft, rings (separator) 5, located in conjunction with the coupling half. The rollers of the intermediate ring with the clutch on are located in the hollow of the torn surface of the coupling halves.

On the circumferential surface of the no; n-clutches 7, in addition to the wedges 1, of their depressions, there are grooves whose depth exceeds the diameter of the driven rollers. When the torque limit is exceeded, under the influence of the torque, the leading coupling half is pressed and, being rolled into the deep grooves of the leading coupling half, they are completely immersed in them. In this position of the drive rollers, the half coupling coupling is automatically disconnected from the coupling half and the coupling between the shafts is stopped. To eliminate the contact of the rollers with the driven coupling half, the ring is spring-loaded with a spring 6.

For reverse engagement of the coupling, carried out manually by the control handle, serves a servo mask 7, located coaxially with the leading palumoufta and rotated with a brake tape 8. When tightening the braking tape, the servo shaft rotates relative to the specified coupling half and acts on axial pushers 9 that squeeze the half coupling. from grooves rollers intermediate kelpa. After the brake has been released, the servoshkine is returned to its original position by the action of the spring 10.
