Description

This invention relates to mechanical engineering and, in particular, to devices for transmitting rotation.

Known clutch, containing two cam 5 coupling halves, interacting when switched through cylindrical speed synchronizers. The disadvantage of the clutch is low reliability, since the switching on the coupling halves does not depend on the speed of their rotation and the teeth can collide.

Closest to the present invention is a clutch containing a driven half coupling with end teeth, hinged inertial masses connected to it, mounted with the possibility of moving in the radial direction, leading to the half coupling with front teeth and mounted on it with the possibility of axial movement of the glass, spring-loaded to inertial masses 2.

The disadvantage of this coupling is low durability due to the narrow range of the non-impact engagement of the coupling halves.

The purpose of the invention is to increase the durability by expanding the range of the non-impact switching of the coupling halves.

The goal is achieved by the fact that a clutch containing a driven half coupling with face teeth, articulated inertial masses connected to it, mounted with the possibility of radial movement, driving coupling half with coupling teeth and mounted on it with the possibility of axial movement of the cup, is spring-loaded. to inertial masses, provided with diametrically located and spring-loaded one to another additional inertial masses mounted on the drive half coupling with

15 . the possibility of radial movement, and the pressure ring installed on the leading coupling half with the ability to interact with the glass and with additional inertial mass gels,

20, while facing one another the surface |: of the pressure ring and additional inertial masses are made scated.

FIG. 1 shows the proposed 25 mA coupling at the time of inclusion; in fig. 2 - the same after switching on.

The clutch consists of a fixed leading coupling half 1 with end teeth, rigidly connected to the shaft 2,

Claims (1)

30 driven half coupling 3 with end teeth positioned with the possibility of axial movement in the axial direction of the rod 4, and the rod 4 is spaced with the possibility of axial movement in the axial hole of the shaft 5. The rod 4 has two fixed positions corresponding to the on state of the coupling (rightmost position) and the state of time and after the clutch is turned on (leftmost position). The driven half coupling 3 is spring-loaded axially away from the leading coupling half 1 of the spring 6. The half coupling 3 is located in the hole 7 of the rod 4, and on the rod 4 there is a bracket 8 rigidly connected with it with radial grooves 9, In grooves 9 with the possibility of radial movement The inertial masses are arranged in the form of sliders 10. The slide blocks 10 are made with clipped bevels 11 and bases 12 parallel to the axis of the coupling. The rod 4 is also equipped with levers 13, fixed to the supports 14. At the ends of the levers 13 are made longitudinal 1, e grooves 15 and 16 in which the supports 17 and 18 are placed, connecting the sliders 10 and the floor 3, respectively. On the outer surface of the half-coupling 1, with the possibility of axial movement, there is a conical shaped cup 19 and a burTNA 20 is provided, the Glass 19 is spring-loaded toward the shoulder 20 by a spring 21. The half-coupling 1 also provides for diametrical grooves 22, in which additional inertial masses 23 are placed, spring-loaded opposite to each other. , with wedge bevels 24, Between the wedge bevels 24 and the end of the spring 21, a pressure ring 25 is installed. The device operates: as follows. In the off state, the rod 4 is in the rightmost position (not shown). In this case, the conical stack 19 abuts flange 20 of the half coupling 1 end of the half coupling 3 - in the end hole 7, and between the bevels 11 sliders 10 and the end of the glass 19 there is a guaranteed gap,. When the clutch is turned on, the rod 4 is moved to the leftmost position. At the same time, the end of the cup 19. lies in the bevels 11 of the sliders 10. At the same time, the spring 21 deforms, Due to the frictional forces entering the place of contact of the bowl 19 and the sliders 10, the half-coupling 3 unwinds. The centrifugal forces of the inertial masses of the sliders 10 will move as far as possible from the center of rotation. When the driven half coupling half reaches the rotational speed of the leading half coupling (relative speeds are equal to zero), the inertial masses of the sliders 10 go beyond the limits of the cup 19. At the same time, using the levers 13, the coupling half 3 moves. given in the direction of the coupling half 1 and the coupling of the end teeth occurs. Stated, as 19, abutted against the base 12 of the sliders 10, reliably fix the coupling in the switched position. The amount of protrusion of the sliders 10 beyond the end of the bracket 8 is chosen such that after coupling between the cup 19 and the end of the bracket 8 there is a gap (to exclude axial loads on the shaft bearings). The coupling is turned off by moving the rod 4 to the extreme right. At different speeds of rotation of the leading half coupling 1. under the action of centrifugal forces, the additional inertial masses 23 will move in radial directions by different values, thereby changing the deformation, spring 21 by axial movement of the pressure ring 25. mass 23 is moved in the radial direction by a large amount, while the pressure ring 25 deforms the source more 21, t, e. to engage the clutch, the driven half coupling must acquire a greater angular velocity, and vice versa. The proposed clutch, by automatically changing the spring stiffness acting on the movable cup, when the angular speed of the leading coupling half changes, allows the range of clutch operating speeds to be expanded, which enhances its operational capabilities. Claims for coupling, containing a driven half coupling with end teeth, hinged inertial masses connected to it, mounted with the possibility of moving in the radial direction, leading to the coupling half with face teeth and mounted on it with the possibility of axial movement of the cup, spring-loaded to the inertial masses, In order to increase durability by providing a shock-free inclusion, it is equipped with diametrically located and spring-loaded one to another additional inertial masses mounted on the leading half coupling with the possibility of radial movement, and a pressure ring mounted on the leading half coupling with the possibility of interacting with the glass and with additional inertial masses, while facing the other of the pressure ring and additional inertial masses are made.
