Description

(54) ОДНООБОРОТНАЯ ЮФТА(54) UNIFORM YFT

Изобретение относитс к машиностроению , в частности к устройствам дл передачи вращени .The invention relates to mechanical engineering, in particular to devices for transmitting rotation.

Известна однооборотна муфта, содержаща две сооснорасположенные полумуфты и фиксатор углового положени ведомой полумуфты 1.A one-turn coupling is known, comprising two coaxially located coupling halves and a latch angular position of the driven coupling half 1.

Недостатком ее вл етс большой, осевой габарит из-за соосного расположени полумуфт.Its disadvantage is a large axial dimension due to the coaxial arrangement of the coupling halves.

Наиболее близкой к изобретению по технической сущности и достигаемому результату вл етс однооборотна муфта, содержаща неподвижную обойму с упором, расположенную в ней ведущую полумуфту, выполненную в виде храпового колеса, охватывающую его ведомую полумуфту и шарнирно закрепленную на ней собачку, подпружиненную к храповому колесу и контактирующую с упором обоймы при отключении полумуфты 2J.Closest to the invention to the technical essence and the achieved result is a one-turn clutch containing a stationary holder with a stop, located in it a coupling half, made in the form of a ratchet wheel, covering its driven coupling half and hinged to it a doggie, spring-loaded to the ratchet wheel and contacting with stop clip when disconnecting coupling half 2J.

Данна муфта характеризуетс низкой надежностью работы из-за отсутстви -фиксации положени собачки при включении и ведомой полумуфты при отключении.This coupling is characterized by low reliability of operation due to the lack of fixation of the position of the pawl when turning on and the driven coupling half when disconnected.

Целью изобретени вл етс повышение надежности работы путем фиксации положени собачки при включеНИИ и ведомой полумуфты при отключении ..The aim of the invention is to increase the reliability of operation by fixing the position of the pawl when it is turned on and the driven half-coupling at shutdown.

Поставленна цель достигаетс тем, что однооборотна муфта, содержаща неподвижную обойму с упором, расположенную в ней ведущую полумуфту , выполненную в виде храпового колеса , охватывающую его ведомую полумуфту и шарнирно закрепленную на The goal is achieved by the fact that a single-turn clutch, containing a stationary holder with an emphasis, is located in it a leading coupling half, made in the form of a ratchet wheel, covering its driven coupling half and hinged on

10 ней собачку, подпружиненную к храповому колесу и контактирующую с упором обоймы при отключении полумуфты , снабжена копиром, закрепленным на обойме, контактирующим с ним 10 her dog, spring loaded to the ratchet wheel and in contact with the stop clip when disconnecting the coupling half, equipped with a cam mounted on the holder in contact with him

15 при включении роликом, смонтированным на собачке, и фиксатором углового положени ведомой полумуфты, смонтированным на обойме и подпружиненным в радиальном направлении к ведомой 15 when turned on by a roller mounted on the pawl and a lock of the angular position of the driven half coupling, mounted on the holder and spring-loaded in the radial direction to the driven

20 полумуфте, при этом ведома полумуфта с пазом под фиксатор, а упор обоймы установлен с возможностью осевого перемещени .20 coupling half, with the knowledge of the coupling half with a groove under the latch, and the stop cage is installed with the possibility of axial movement.

Claims

The tooth of the ratchet wheel is made obliquely at half their height, their side surfaces are located 6 planes passing through the axis of rotation, and the toe of the doggie is made 30 in the shape of the slots of the ratchet wheel. Pa fng. 1 shows the proposed coupling, cross section; in FIG. 2, the R-LL in FIG. one; in fig. 3 crown of the ratchet and the sock of the dog at the moment of engagement of the clutch. The clutch contains a leading coupling half 1, made in the form of a ratchet wheel together with the gear, and freely mounted on the shaft 2. The coupling half 1 interacts with the gear wheel 3. Fa shaft 2 is fixed by means of a key 4 to the coupling half 5. covering ratchet crown of the coupling half 1. On the coupling half 5, a doggie 7 is freely mounted on the axis b, spring-loaded 8 fixed on the coupling half 5. In the nose part of the doggie 7, rollers 10 are mounted on the axis 9 of the doggate. is made with a groove above the shank of the pawl 7 and the cam 13. On the cage 12 there is a lock 14, spring-loaded spring 15. and a bracket 16, in which a controlled stop 17 is located. The ratchet tooth 18 of the half-coupling 1 is made with a bevel on the back side half of its height, and the side surfaces 19 of the grooves are radial. The working surface 20 of the nose part of the dog 7, interacting with the groove of the ratchet crown of the coupling half 1 is made in the shape of the grooves of the ratchet wheel. The clutch works as follows: By a signal from the control unit (without showing the controlled stop 17 and the latch 14 is retracted to the left. The dog 7, under the action of the spring 8, turns on the axis b and the axial nose approaches the ratchet wheel of the half coupling 1. The half coupling 1 rotates constantly from drive (not shown by gears and gears 3. The nose of the pawl 7, get on the tooth of the ratchet wheel of the coupling half 1, slides over its cut off part and engages with the ratchet. The coupling half 5 starts to rotate. After turning the coupling half 5 at some angle rollers 10, interacting with the cam 13 of the sleeve 12, press the pawl 7 into the slot of the ratchet wheel of the half coupling 1, blocking it from spontaneous disengagement under the action of external forces, such as inertia forces or alternating loads. t out of contact with the cam 13 of the yoke 12. The dog 7 interacts with the tail section with the steerable abutment 17, which has returned to its original position simultaneously with the latch 14 according to the command device signal, and is disengaged from the ratchet wheel of the coupling halves 1. Spring-loaded latch 14 into the socket zapadet coupling half 5 and the latter is fixed. Then the cycle repeats. The use of the proposed device eliminates the possibility of proscal. driven coupling half relative to the leading with alternating loads, increasing the reliability of the coupling. Claim 1.
