The clutch and brake between the coaxial inner shaft and the coaxial outer shaft are realized in the following mode.
The supporting base 6 is fixed with the outer fixing plate 3, and power is transmitted from the first side direction of the transmission shaft 2, so that the transmission shaft 2 rotates to drive the rotating body 16 to synchronously move. When the friction plate is not active, the drive shaft 16 is separated from the outer sleeve 1. The way in which the outer sleeve 1 moves is now uncertain. The voice coil motor 5 is started to move towards the first side of the transmission shaft 2, and then the moving component (the movable baffle 10, the thrust ball bearing 11 and the bearing support frame 12) is driven to move rightwards through the baffle ring 4. At this time, the third friction plate 13 moves rightward, and friction or engagement with the fourth friction plate 14 occurs (the different friction plates function differently). The friction generated therebetween causes the moving member to move in synchronization with the rotating body 16. Since the outer sleeve 1 is connected to the movable barrier 10 (part of the moving member) by the outer connecting key groove 7, the outer sleeve 1 moves in synchronization with the drive shaft 2 at this time. The voice coil motor 5 is moved leftwards by changing the movement direction of the voice coil motor 5, the voice coil motor 5 drives the moving member to move leftwards through the baffle ring 4, and the third friction plate 13 is separated from the fourth friction plate 14. At this time, the first friction plate 8 and the second friction plate 9 are rubbed or engaged. Since the outer fixing plate 3 connected to the first friction plate 8 is fixed, the movable barrier 10 is fixed, so that the outer sleeve 1 is also fixed and the transmission shaft 2 is rotated.
According to the utility model, the voice coil motor 5 moves left and right to drive the moving member to move left and right, so that the first friction plate 8 is separated from or meshed with the second friction plate 9, the third friction plate 13 is meshed with the fourth friction plate 14, and the transmission shaft 2 continues to rotate when the outer sleeve 1 is fixed, and the outer sleeve 1 and the transmission shaft 2 synchronously rotate. Because the left and right movement stroke of the moving component is small, the clutch-brake process time is short and the efficiency is high.
The clutch and brake device for the coaxial shaft designed by the utility model has the advantages of small volume, simple mechanism, high reliability, large friction force, realization of dual functions of clutch and brake, short clutch-brake process time and high efficiency.
The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
