Small sliding block type low-speed clutch

Abstract

The invention discloses a small sliding block type low-speed clutch which comprises a sliding block. A through hole is formed in the middle of the sliding block. The central axis of the through hole deviates from the geometric center of the sliding block. A power input shaft is in threaded connection with the through hole. A boss is arranged on the outer edge of the sliding block. The power input shaft is sleeved with a connecting sleeve. A left end cover is fixed to one end of the connecting sleeve and connected with the power input shaft through a left conical roller bearing. A right end cover is fixed to the other end of the connecting sleeve and connected with the power input shaft through a right conical roller bearing. The sides, close to the sliding block, of the left end cover and the right end cover are provided with grooves capable of being meshed with the boss. The end faces of the left end cover and the right end cover are each provided with installation holes and threaded holes. According to the small sliding block type low-speed clutch, clutching of the clutch can be achieved only through self-rotation of the power input shaft with no need of external force, the principle and the structure are simple, and the problem of power connection and disconnection of small mobile equipment under the special environment is solved.

Description

technical field [0001] The invention relates to a clutch, in particular to a small slider type low-speed clutch. Background technique [0002] A clutch is like a switch, its main function is to engage or disengage power transmission. The active part and the driven part of the clutch mechanism can be temporarily separated and gradually engaged. The active part and the driven part of the clutch rely on the friction between the contact surfaces, or use liquid as the transmission medium (hydraulic coupling), or Use magnetic transmission (electromagnetic clutch) to transmit torque, so that the two can be temporarily separated and gradually engaged. But above-mentioned clutch all needs to make clutch action by external force, as manpower (pedal), electromagnetic force etc. [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 environmen...

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
