A small normally open high-speed clutch

Abstract

The invention discloses a small normally open high-speed clutch, which comprises a power input shaft, the power input shaft is connected with the center hole of the turntable through a key, the outer surface of the turntable is provided with a cylindrical pin hole, and the cylindrical pin hole is provided with a cylindrical pin, and the cylindrical pin It is connected with the bottom of the cylindrical pin hole through a tension spring; the connecting sleeve is set on the turntable, the inner side of the connecting sleeve is provided with a groove matching the cylindrical pin, the outer side of the connecting sleeve is provided with a keyway, and the left end cover is fixed on one end of the connecting sleeve by a hexagon socket head screw , the right end cover is fixed on the other end of the connecting sleeve through a hexagon socket head cap screw, and tapered roller bearings are arranged between the left end cover and the power input shaft and between the right end cover and the power input shaft. The small normally open high-speed clutch can realize the clutch clutch only by the rotation of the power input shaft itself without external force.

Description

Technical field [0001] The invention relates to a clutch, especially a small normally open high-speed clutch. Background technique [0002] A clutch is similar to a switch, and its main function is to engage or disconnect power transmission. The driving part and the driven part of the clutch mechanism can be temporarily separated, and can be gradually engaged. The driving part and the driven part of the clutch rely on the friction between the contact surfaces, or use liquid as the transmission medium (fluid coupling), or A magnetic drive (electromagnetic clutch) is used to transmit the torque, so that the two can be temporarily separated and gradually engaged. However, the above-mentioned clutches all require external force, such as manpower (pedal), electromagnetic force, etc., to make the clutch actuate. [0003] For some machinery used in special occasions, conventional clutches cannot meet application requirements. For example, for rescue robots or unmanned mobile equipment ...

Problems solved by technology

[0003] For some machinery used in special occasions, conventional clutches cannot meet the application requirements

For example, for rescue robots or unmanned mobile equipment with explosive gas environments in coal mines, chemical plants, etc., conventional clutches have three disadvantages: First, such equipment is small in size, while conventional clutches Compared with this type of equipment, it is relatively large (such as a hydraulic coupling), and it is not suitable to be installed on this type of equipment

Second, such equipment is usually operated by remote control, which cannot be realized for clutches that require manual clutching (such as friction clutches)

Third, if a separate actuator is added for the clutch action of the clutch, or an electromagnetic clutch is directly used, for equipment used in explosive gas environments, an additional explosion-proof structure is required, which will greatly increase the design cost. Complexity
