Automatic clutch device with free stroke and rotating door mechanism

Abstract

The invention provides an automatic clutch device with the free stroke. The automatic clutch device comprises a first drive shaft, a clutch drive part and a second drive shaft; the first drive shaft is in drive connection with the second drive shaft through a clutch drive component, the first drive shaft is a ladder shaft, threads are arranged on the surface of a small end shaft of the first drive shaft, and the clutch drive component is rotatably arranged on the threads; a baffle used for blocking the clutch drive component is arranged on the end face of the small end of the first drive shaft, a counter bore is formed in the end face of one end of the second drive shaft, and the small end of the first drive shaft, the clutch drive component and the baffle are all embedded in the counter bore; the clutch drive component and the second drive shaft are connected in a torque transmission manner and can slide axially relative to the inner wall of the counter bore; and compared with the prior art, the automatic clutch device is simple in structure, reasonable in design, convenient to manufacture, reliable in torque transmission, wide in application range and high in practicability, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of clutch transmission equipment, in particular to an automatic clutch device with free travel and a revolving door mechanism using the clutch device. Background technique [0002] In the field of mechanical applications, for some shaft mechanisms that require free travel, at present, electromagnetic clutches are combined with controllers to control the torque transmission between shafts and shafts. The structure of electromagnetic clutches is relatively complicated, and the production cost is relatively high. At the same time, the control system is added, the whole system is more complicated and the cost is high, and if a simple missing block structure is used for torque transmission, due to the large driving force when the shaft is rotating, the missing blocks on the two shafts will be in contact. At the moment, there will be a lot of noise and vibration at the same time, which will affect the quality of u...
