SU397697A1 - COUPLING CLUTCH FOR COMMUNICATION OF THE SLAVE INTERMEDIATE MOTION - Google Patents

Description

one

The invention relates to mechanical engineering and can be applied in devices where periodic operation of individual components and mechanisms with a certain degree of continuous operation of other mechanisms is necessary in the case of their drive from a single engine.

A known clutch for intermittent motion to the driven shaft, comprising a leading coupling half and periodically connected with the control mechanism of the driven coupling half. The control mechanism is made in the form of a lever connected to the electromagnet and moving the axially movable coupling half, which is axially movable and equipped with grooves, into which the pin-lock enters when it stops.

The purpose of the invention is the innovation of reliability and accuracy of the clutch.

It is achieved by the fact that in the proposed clutch the control mechanism is made in the form of two copiers, one of which is connected to the driven coupling half by means of brake pads installed concentric to it, and the other by means of a spring-loaded tongue fixed on the driving coupling half and interlocked with the ratchet wheel mounted in the coupling half coupling.

A-A in FIG. one; in fig. 3 shows a section according to FIG. one.

The drive shaft 3 has a drive shaft 3 in the sleeves 2 in the sleeves 2 and a driven shaft 5 in the sleeves 4. The drive coupling is fixed to the drive shaft 6, in the slot 7 of which the tongue 8 is moved, held by two bars 9. The key is fixed to the pin 10, which is the axis rotation of the roller 11, which during operation rolls over the copier 12 mounted on the Cornus. The grooves 13, through which the copier is attached to the body, can change the footprint of the copier until the moment it is turned off. Spring 14 all the time presses pshonka to the inner surface 15 of the driven half-coupling 16, having 1, ratchet cutting it.

Driving coupling coupled on the driven shaft. The pads 17 and 18 with the lining 19 of fricciopoopic material are installed in the housing on the finger 20. The ends of the pads 21 are formed with a spring 22. Between the pads, a cam 24 with a lever 25 is mounted on the pox 23. The roller 27 is mounted on the end 26 of the lever 25, all the time pressed against the side surface 28 of the copier 29, located on the hub 30, mounted on the drive shaft.

When the drive shaft 3 rotates with the leading half coupling 6 of the pin 8, the spring 14 is pressed against the inner surface of the driven luminft 16. At the same time, the key 8 with its

whose face 31 rests on radial steep 32 of tooth 33 and carries away the driven half coupling. The roller 27 of the lever 25 at this time rolls over the side surface 28 of the copier 29, the cam 24 at the same time unclenches the brake pads 17 and 18, and a gap is formed between them and the outer wall 34 of the driven half-coupling 16, which is driven by the half-coupling. The clutch rotates as one piece.

Upon further rotation of the coupling, the roller 11 begins to roll along the lead-in part 35 of the copier 12, and the key 8 begins to move radially to the axis of the drive shaft 3, slipping its working face 31 along the radial wall 32 of the tooth 33 of the ratchet wheel of the driven half-coupling 16. When the roller rolls to the top 36 the copier 12, the key exits from the engagement with the tooth 33, and the driven coupling half stops. Its exact stopping with the elimination of inertial forces is provided by the brake pads 17 and 18, since at the time the key 8 comes out of engagement with the tooth 33, the roller 27 enters the recess 37 of the side surface 28 of the copier 29, the lever 25 with the cam 24 rotates under the action of the spring 22 and the pads are compressed around the driven coupling half 16.

Upon further rotation of the leading half coupling 6, the key 8 converges on the copier 12 and engages with the next ratchet tooth, while the roller 27 begins to roll along the side surface 28 of the copier 29, and the pads are moved apart. In this way, the slave coupling half 16 is carried out while the driving coupling half is stationary

Coupling clutch for intermittent motion to the driven shaft, containing the drive unit and intermittently connected to it via a control mechanism

Driven coupling half, characterized in that, in order to increase reliability and accuracy of operation, the control mechanism is made in the form of two copiers, one of which is connected to the driven coupling half by means of stacked concentric brake shoes, and the other mounted on the leading coupling half and coupled to the ratchet wheel mounted in the driven coupling half.
