(54) МУФТА СВОБОДНОГО ХОДА(54) CLUTCH COUPLING

II

Изобретение относитс к машиностроению .The invention relates to mechanical engineering.

Известна муфта свободного хода, содержаща колесо с зубь ми и обойму, между которыми расположены сцепные эле1 | енты; взаимодействующие с зубь ми колеса и установленные шарнирно на обойме 1.A freewheel is known, containing a wheel with teeth and a yoke between which coupling elements are located | awards; wheels interacting with the teeth and hinged on the holder 1.

Изготовление и установка сцепных элементов в такой муфте усложн ют ее конструкцию .The manufacture and installation of coupling elements in such a clutch complicates its design.

Известна муфта свободного хода, содержаща колесо с зубь ми, обойму с пазами и расположенные между ними подпружиненные сцепные элементы 2.A one-way clutch is known, comprising a wheel with teeth, a clip with grooves and spring-loaded coupling elements 2 located between them.

Однако така муфта имеет сложную конструкцию .However, this coupling has a complex structure.

Цель изобретени - упрощение конструкции муфты.The purpose of the invention is to simplify the design of the coupling.

Поставленна цель достигаетс тем, что пазы обоймы выполнены радиальными, а сцепные элементы установлены в них с возможностью радиального перемещени и имеют выступающие концы на торцах муфты, при этом пружины, охватывающие сцепные элементы, расположены на выступающихThe goal is achieved by the fact that the grooves of the cage are made radial, and the coupling elements are installed in them with the possibility of radial movement and have protruding ends at the ends of the coupling, while the springs covering the coupling elements are located on the protruding

концах, а зубь звездочки выполнены храповыми .ends, and the sprocket teeth are made ratchet.

На фиг. 1 показана муфта, осевой разрез; на фиг. 2 - вид сбоку с частичным вырывом; на фиг. 3 - первый вариант зубьев колеса; на фиг. 4 - второй вариант зубьев колеса.FIG. 1 shows the coupling, axial section; in fig. 2 - side view with partial tearing; in fig. 3 - the first version of the teeth of the wheel; in fig. 4 - the second version of the teeth of the wheel.

Муфта свободного хода содержит колесо 1 и обойму 2, между которыми расположены сцепные элементы 3, выполненные в виде расположенных параллельно оси муфты цилиндрических стержней. Обойма 2 охватывает с зазором колесо 1 и состоит из соединенных между собой болтами 4 кольца 5 с торцовыми фланцами 6 и 7,The freewheel includes a wheel 1 and a yoke 2, between which are coupling elements 3, made in the form of cylindrical rods arranged parallel to the axis of the coupling. The yoke 2 covers with a gap the wheel 1 and consists of interconnected bolts 4 rings 5 with end flanges 6 and 7,

которые установлены на подщипниках 8 и 9 ведущего вала. Кольцо 5 центрируетс по диаметру фланцев 6 и 7 и может быть выполнено в виде зубчатого колес или шкива ременной передачи.which are mounted on sub-bearings 8 and 9 of the drive shaft. The ring 5 is centered on the diameter of the flanges 6 and 7 and can be made in the form of gears or a belt drive pulley.

Claims

The radial clearance between the teeth 10 of the wheel 1 and the ring b slightly exceeds the diameter of the coupling elements 3. The flanges 6 and 7 have evenly spaced radial grooves 11 and 12, in which the coupling elements 3 are freely arranged, the ends of which protrude at both ends of the coupling and are mounted on them rollers 13. The rollers 13 are enclosed by an annular elastic element 14, for example a tension spring, which presses the coupling elements 3 against the teeth of the 10 wheels 1 with a slight force. From axial displacement, the coupling parts are held by covers 15. The tooth 10 of the wheel 1 has the shape of ratchet teeth and can be made in two versions. In the first embodiment, the GO tooth side 16 has a concave surface, and in the second variant, the operative side of the tooth 17 is inclined to the radius passing through the centers of the wheel 1 and coupling elements 3 at an angle smaller than the friction angle. The tooth profile, made according to the second variant, allows to increase the uniform distribution of the load between the teeth, automatically compensating for errors in the manufacture of teeth, coupling elements and grooves in the flanges. The internal cavity of the coupling can be filled with grease. The clutch works as follows. When the drive shaft and the wheel 1 rotates counterclockwise, the working side of the teeth 10 is pressed against the coupling elements 3, which carry the holder 2. When the wheel 1 rotates clockwise relative to the holder 2, its ratchet teeth, in contact with the coupling elements 3, move them to the slots of the flanges 6 and 7 in the radial direction and freely slip under them. Claims The overrunning clutch comprising a wheel with teeth, a clip with grooves and spring-loaded coupling elements located between them, characterized in that, in order to simplify the design, the grooves of the clip are made radial, and the coupling elements are installed in them with the possibility of radial movement and have protruding ends at the ends of the coupling, while the springs covering the coupling elements are located at the protruding ends, and the sprocket tooth is made ratchet.
