Description
Technical Field
The invention relates to the field of mechanical engineering, in particular to a reversible clutch.
Background
The spring reset actuating mechanism is an electric actuating mechanism capable of resetting rapidly when power is lost, and in order to realize the function of power-loss reset, the transmission mechanism and the gear motor are required to be separated when power is lost. In the actual use process, a reversible clutch which can realize synchronous rotation of the driven shaft when the driving shaft rotates in the forward direction and can not rotate when the driven shaft rotates in the reverse direction is needed.
Disclosure of Invention
The invention aims to solve the technical problems that: the invention provides a reversible clutch to solve the problems when a driving shaft rotates in the forward direction and a driven shaft rotates in the reverse direction.
The technical scheme adopted for solving the technical problems is as follows: the reversible clutch comprises a bidirectional clutch and a unidirectional gear, wherein the bidirectional clutch comprises an inner ring and an outer ring, a retainer is arranged below the outer ring, the lower end face of the retainer is connected with the upper end face of the inner ring, a ball bearing and a ball are arranged between the inner ring and the outer ring, and the ball bearing is positioned above the ball bearing; the one-way gear comprises a gear shaft and a bearing seat, the bearing seat is positioned above the gear shaft, a bearing and a one-way bearing are arranged on the inner side of the bearing seat, the one-way bearing is positioned above the bearing, and the gear shaft is meshed with a retainer of the two-way clutch.
Specifically, the bidirectional clutch is a bidirectional overrunning clutch.
The invention has the advantages that when the spring reset actuating mechanism works normally, the driving shaft of the transmission mechanism rotates forward, the driven shaft rotates synchronously, when the spring reset actuating mechanism loses power, the transmission mechanism resets rapidly, and as the transmission mechanism can realize the reverse rotation of the driven shaft and the driving shaft does not rotate, the transmission mechanism and the gear motor are separated rapidly, the operation of the equipment is safer, and the energy consumption is reduced greatly.
Drawings
The invention will be further described with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the present invention.
Wherein: 1. a bi-directional overrunning clutch; 2. a one-way gear; 3. an inner ring; 4. a retainer; 5. an outer ring; 6. a roller; 7. a ball bearing; 8. a tooth shaft; 9. a bearing seat; 10. a bearing; 11. a one-way bearing.
Detailed Description
The present invention will be described in further detail below with reference to the drawings and examples for the purpose of enhancing the understanding of the present invention.
Referring to fig. 1, the invention provides a reversible clutch, which comprises a bidirectional overrunning clutch 1 and a unidirectional gear 2, wherein the bidirectional overrunning clutch 1 comprises an inner ring 3 and an outer ring 5, a retainer 4 is arranged below the outer ring 5, the lower end surface of the retainer 4 is connected with the upper end surface of the inner ring 3, a ball bearing 7 and a ball 6 are arranged between the inner ring 3 and the outer ring 5, and the ball bearing 7 is positioned above the ball 6.
The unidirectional gear 2 comprises a gear shaft 8 and a bearing seat 9, the bearing seat 9 is positioned above the gear shaft 8, a bearing 10 and a unidirectional bearing 11 are arranged on the inner side of the bearing seat, the unidirectional bearing 11 is positioned above the bearing 10, and the gear shaft 8 is meshed with the retainer 4 of the bidirectional overrunning clutch 1.
When the inner ring 3 is a driving shaft, the retainer 4 and the outer ring 5 are driven to synchronously rotate through the rollers 6, the outer ring 5 is a driven shaft, and the unidirectional gear 2 synchronously rotates due to the fact that the retainer 4 is meshed with the gear shaft 8 and the unidirectional gear 2 can only rotate in one direction by utilizing the characteristic that the unidirectional bearing 11.
When the outer ring 5 is a driving shaft, the retainer 4 and the inner ring 3 are driven to synchronously rotate through the roller 6, and the inner ring 3 is a driven shaft.
The outer ring 5 is the driving shaft, and at the same time, when the retainer 4 is fixed, the inner ring 3 and the outer ring 5 are separated, and the unidirectional gear 2 does not rotate.
When the inner ring 3 is a driving shaft, the unidirectional gear 1 synchronously rotates, and the outer ring 5 (driven shaft) synchronously rotates; when the outer ring 5 is a driving shaft, the unidirectional gear 1 does not rotate, the inner ring 3 does not move, and the inner ring 3 and the outer ring 5 are separated.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the present invention and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present invention.
