SU1523795A1 - Device for converting reciprocation to interruptive rotation - Google Patents

Abstract

The invention relates to mechanical engineering and can be used in various mechanisms with intermittent rotation of the driven member. The purpose of the invention is to simplify the design of the device. A reciprocating movement is mounted on cylinder 5 perpendicular to its axis with the possibility of moving a slider 7 on which two gear racks 8 and 9 are fixed. A roller is mounted on the slider, which in the extreme positions of cylinder 5 interacts with 10 stops mounted on the base and 12, allowing the slider 7 to move alternately to engage the rails 8 and 9 with the gear 1. 5 sludge.

The invention relates to mechanical engineering, in particular to motion transducers, and can be used in various mechanisms with intermittent rotation of the driven link.

The purpose of the invention is to simplify the design due to another implementation of the mechanism for controlling the alternating engagement of the rails.

A device for converting reciprocating motion into. intermittent rotary contains a gear wheel 1, a power pneumatic cylinder 2, which pordpen 3 with a two to 25 external rod 4 is filled with a stationary one, and the cylinder 5 with a possibility of reciprocating movement with control from the distributor 6. On the cylinder 5 it is perpendicular to its axis. slider 7 is mounted for movement, toothed rails 8 and 9 are fixed on the slider, and on the base 10 there are left and right stops 11 and 12, which provide alternate engagement of the rails with the gear wheel at the end of the cylinder stroke by means of a roller 13, which interacts with the inclined surfaces of the stops 11 and 12. Two hemispherical slots 14 are made to fix the slider 7 in the extreme positions, and a spring-loaded ball lock 15 is fitted in the cylinder, which falls into one of the slots 14. The direction of movement of the cylinder 5 is provided by the guide 16 .

The device works as follows.

 Cylinder 5 is, for example, in the extreme right position, with

When the compressed air feeds into the right cavity of the cylinder 5, it moves to the right and the wheel 1 rotates counterclockwise, interacting with the rail 8. The cylinder moves to the extreme right position and the cycle repeats .

In order to obtain a unidirectional rotation of the wheel 1 clockwise, the stops 11 and 12 must be swapped.
