Description

(54) COUPLING

The invention can be used .40 in mechanical engineering in low-speed drives, for example, for opening valves or flaps.

Known clutch on the main bus sv. No. 463819, containing the outer half coupling with stops on the inner surface and interacting with the drive rollers mounted on the levers mounted on the inner coupling half, and the control device in the form of a spring-loaded sleeve mounted on the shaft of the inner coupling half with the possibility of axial alternation by means of a plug mounted on it and an interacting outer surface with locking rollers fixed on the levers flj. .

To quickly disengage the clutch under unfavorable operating conditions, for example, after a prolonged stay of the clutch in a stationary state (drying of the lubricant) or at low. temperature pax (lubricant freezing) requires an increase in the component force from the working load (i.e. a decrease in the angle of inclination of the stops of the outer coupling half) or an increase in the force of the additional spring

These measures lead to an increase in the pressure of the locking rollers on the control sleeve and consequently to an increase in the force required to control the clutch release.

The aim of the invention is to increase the speed of the coupling.

The objective is achieved thanks to the fact that the coupling arms according to the invention are made with two shoulders with control rollers mounted on them, and the sleeve has additional conical projections interacting with the control rollers.

FIG. 1 shows the proposed coupling, a longitudinal section; in fig. 2 is given a section along A-A in FIG. one.

The clutch contains the outer coupling half 1 with the leading inclined stops and the inner coupling half 2, rigidly connected to the bucket shaft 3.

On axle x 4 (fig. 2), fixed in half coupling 2, two shoulders levers 5 are installed with leading 6, locking 7 and controlling 8 rollers.

The control sleeve 9 fits freely on the driven shaft 3 and is spring-loaded through the pin 10 and the cup 11 by the spring 12 The locking rollers 7 interact with the cylindrical projections 13, and the control rollers 8 with the conical projections 14 of the bush 9. The control fork 15 is set axis 16 and interacts with the sleeve 9. With the rotation of the coupling half 1 in the direction indicated by the arrow in FIG. 2, its angles through the rollers 6 and the levers 5 drive the coupling half 2 and the driven shaft 3 associated with it, while the control sleeve 9 through the fixing rollers 7 keeps the levers 5 in the engaged state. When a force P is applied to the control fork 15, the sleeve 9 moves, compressing the spring 12, and first releases it, gives the fixing rollers 7, after which the drive rollers roll out from the slots of the coupling half 1 and disengage the coupling half. If, after releasing the fixing rollers 7, the leading rollers 6 due to the increased friction hang on the inclined stops of the half-coupling 1, the freely lower sleeve 9 at the end of the stroke hits

Claims (1)

FIG. 1 with its conical protrusions 14 along the control rollers 8 and forcibly disengaging the rollers 6 with inclined stops of the half coupling 1. When the force P is removed from the fork 15, the sleeve 9 returns to its original position. At the same time, the control rollers first roll off the inclined projections 14. 8, after which the levers 5 are released and can be diluted to their original position by the protrusions 13 of the sleeve 9. Formula of the Invention Coupling according to ed. St. 463819, characterized in that, in order to increase its speed, the levers1 are made by two shoulders with control rollers mounted on them, and the sleeve has additional conical projections interacting with the control rollers.
