Abstract

The invention relates to mechanical engineering and is intended to transmit intermittent rotational movement from one shaft to another. The aim of the invention is to increase reliability. When sector 1 is rotated, a certain angle of the wheel 9 rotates. When the last tooth of sector 2 is in engagement with the wheel 9, it is retracted from the wheel 9 before the loads on the tooth become maximum due to the specific performance of the cam profile 7. 4 Il SL CO 4; 4 of FIG. g

Description

The invention relates to mechanical engineering and can be used to transmit intermittent rotational movement from one shaft to another.

The purpose of the invention is to increase reliability by reducing the loads on the teeth and simplifying the adjustment of the values of the nodes of rotation.

FIG. 1 shows a gear mechanism of intermittent motion, a general view; on

A uniform rotation of sector 1 drives the wheel 9 to rotate. All the teeth of sectors 1 and 2 during the operating cycle transmit the rotational moment g to the wheel 9. The tooth of the rotary sector 2 is stationary relative to the axis 4, as its roller 6 rolls over the working section 10 a fixed cam 7. As soon as the last tooth of sector 1 is disengaged by the teeth of the wheel 9,

The gear mechanism of perverse movement contains a leading half-teeth gear, made in the form of two sectors 1 and 2. The sector is rigidly connected to the shaft 3. Sector 2 is pivotally connected to sector 1, with the hinge axis 4 being offset radially relative to the axis of the shaft 3 of sector 1, and on sector 2 itself, an emphasis 5 is made with a roller 6 interacting with a fixed cam 7, coaxial sectors 1 and 2 and mounted on the axis of the shaft 3 by means of a bearing unit 8. Sectors 1 and 2 interact with

when roller 6 moves around sector 2 relative to axis 4, the teeth of sector 2 and the driven wheel 9 are disengaged, and the moment of uncoupling can be selected before the maximum load of the last tooth of sector 2. 6 to section 12 of the cam 7. The mechanism returns to its original position and the cycle repeats.

Invention Formula The intermittent gearing mechanism contains a leading half-toothed tooth with a worn wheel 9. Cam 7 has three rails made in two sectors, the barrel section: section 10, made with a radius for rolling the roller 6 to form sectors 1 and 2 of one whole wheel (sectors); a section 11 for instantly withdrawing a sector 2 from engaging its tooth with the teeth of a wheel 9; and a portion 12 serving to rotate sector 2 to its original position. The gear mechanism of intermittent motion works as follows. thirty the first of which is rigidly connected to the shaft, and the second is hinged to the first, and a slave wheel interacting with sectors, characterized in that, in order to increase reliability, the mechanism is equipped with a fixed cam, coaxial sectors, the axle of the coupling sector is offset from the axis of the shaft, and in the second sector there is an emphasis with a roller interacting with a fixed cam. A uniform rotation of sector 1 drives the wheel 9 to rotate. All the teeth of sectors 1 and 2 during the work cycle transmit the rotational moment to the wheel 9. The tooth of the rotary sector 2 is stationary relative to axis 4, as its roller 6 rolls over the working section 10 of stationary cam 7. As soon as the last tooth of sector 1 is disengaged by the teeth of wheel 9, until the roller 6 moves to the section 11 of the cam 7. When the sector 2 rotates about the axis 4, the teeth of the sector 2 and the driven wheel 9 are disengaged, and the moment of uncoupling can be selected before the maximum load on the last tooth of the sector 2. When roller 6 moves to cam section 12, the mechanism returns to its original position and the cycle repeats.
