Description

I

The invention relates to mechanical engineering and can be used in devices and devices with a step motion of the driven link.

The purpose of the invention is to increase reliability.

Figure 1 shows a diagram of the mechanism in figure 2 - section aa in figure 1, in fig.Z - section bb in figure 1, figure 4 - section-bb In figure 1. .

A mechanism for converting continuous rotary motion into rotary with stops includes a housing 1, a driven shaft 2 mounted on it with a stop 3 fixedly mounted on it and a half-toothed gear wheel 4, interacting with gear 5 fixedly mounted on the drive shaft 6. A stop 3 and the half-toothed gear the wheel 4 is held in a certain position by the device 7 dp controlled by a stopper made in the form of a pneumatic cylinder 8 with a rod. In this position against the gear 5 there is a part of the half-eared wheel 4, devoid of teeth. On the driven shaft 2, a gear wheel 9 is mounted on bearings (not shown), equipped with a splined shaft-bushing 10 with a movable cam coupling 11 mounted on it, interacting through the control device of the stopper 7 with the cam coupling half 12 rigidly coupled to the half-edent gear 4.

The gear wheel 9 is in constant engagement with the gear 13, Fixed on the drive shaft 6. The gear 14 is rigidly mounted 5 on the driven shaft 2 and interacts with the gear wheel 15 of the driven link 16.

The mechanism for converting a continuous rotational movement into a rotational one, with stops, operates as follows.

From the drive shaft 6, through gear 13, the rotation is transmitted to the gear wheel 9. The gear wheel 9 with the cam half coupling 11 rotates freely on the shaft 2. When the control device of the stopper 7 is activated, the stopper 3 is released, and the cam half coupling 11 engages with the coupling half 12 of the partial gear 14 and turns the driven shaft 2. The rotation through the gears 13 and 14 is transmitted to the driven link 16.

The half-toothed wheel 4 smoothly engages with the gear 5 and rotates one turn until the teeth come out of the engagement, occupying the initial position. If the control device is stopped by the stopper 7, the half-coupling 11 is disengaged and the stopper 3 is locked by the stem of the control device 7. With the control device permanently engaged, the half-coupling 11 does not come out of the engagement and the shaft 2 gets a continuous rotation.
