(5) ПРУЖИННАЯ МУФТА(5) SPRING COUPLING

II

Изобретение относитс к машино .строению и предназначено дл сцеплени и расцеплени валов.The invention relates to a machine and is intended for coupling and disengaging shafts.

Известны сцепные конусные муфты, содержащие две полумуфты с взаимодействующими друг с другом фрик14ионными конусными поверхност ми 1 .; Наиболее близкой к предлагаемой вл етс пружинна муфта,содержаща управл ющую обойму, расположенные соосно ведущую и ведомую пoлyмyфtы, охватываемые пружиной, соединенной ,с ведущей полумуфтой и управл ющей обоймой. 12.Coupling cone couplings are known, which contain two coupling halves with frictional conical surfaces interacting with each other 1.; Closest to the present invention, there is a spring clutch comprising a control holder, arranged coaxially with the driving and driven members of the coupling, covered by a spring, connected with the driving coupling half and the driving support. 12.

Недостатком известной муфть вл етс то, что она не может передавать реверсивный вращающий момент.A disadvantage of the known sleeve is that it cannot transfer reverse torque.

Цель изобретени - расширение функциональных возможностей муфты .путем обеспечени ее реверсировани .The purpose of the invention is to enhance the functionality of the coupling. By ensuring its reversal.

Поставленна цель достигаетс тем, что муфта, содержаща управл ющую обойму, ведущую и ведомую полу муфты, охватываемые пружиной, соединенной с ведущей полумуфтой.и управл ющей обоймой,, снабжена корпусом и подпружиненным относительно него в осевом направлении, кольцом . с внутренней конусной поверхностью, ведома полумуфта выполнена в виде двух барабанов, жестко соединенных . с корпусом и установленных по обе стороны от ведущей полумуфты, при этом управл юща обойма выполнена The goal is achieved by the fact that the clutch containing the control clip, the drive and the driven half of the coupling, covered by a spring connected to the drive half coupling and the control clip, is provided with a housing and is spring-loaded relative to it in the axial direction, a ring. with the inner conical surface, the half coupling coupling is made in the form of two drums rigidly connected. with housing and installed on both sides of the leading coupling half, while the control holder is made

20 on both sides of the coupling half 3- The coupling half is covered by a spring L, connected by a middle part. A with coupling half 3 and ends B with a control collar 5 installed with bearings 6 in case 2. In case 2, the ring 7c is mounted for movement in the axial direction, the inner conical surface is spring-loaded relative to the housing 2 by a spring 8. The guides 9 fix the ring 7 relative to the body. 2 in the circumferential direction. The control collar 5 is made with a conical surface interacting with the conical surface of the ring 7. The coupling works as follows. In the absence of the control force, the spring 8 pushes the ring 7 to the extreme upper position through the guides 9, while the spring k is in a free state, the coupling halves 1 and 3 are not interconnected and the torque is not transmitted. When a control force is applied to the guides 9, the spring 8 is compressed and the conical friction surfaces of the ring 7 and the sleeve 5 are connected. As a result The casing 5 is fixed relative to the housing 2 and when the half coupling 3 rotates the spring coiled onto the coupling half 1. Due to the friction of the spring C with the coupling half 1, the torque from the coupling half 3 to the coupling half 1 is transmitted. Depending on the direction of rotation of the coupling half 3, the moment is transmitted or the upper or the lower part of the spring. When the control force is removed from the guides 9, the spring 8 opens the ring 7 and the holder 5 and under the action of the elastic forces of the spring k the holder 5 rotates relative to the housing 2, and the spring C releases the coupling half 1 and the kinematic coupling between the coupling half 1 and 3 is broken. In this way, the clutch transmits a reversal torque, in addition, the clutch ensures smooth switching due to the elasticity of the spring. This extends the functionality of the proposed coupling. Claims of the invention A spring-loaded clutch comprising a control clip, coaxially driving and driven half couplings, covered by a spring connected to the coupling half and a control sleeve, characterized in that, in order to extend the functionality by reversing it, it is provided with a covering sleeve and an axially spring-loaded ring with an inner conical surface, driven by the coupling half, is made in the form of two drums rigidly connected to the body and set claimed on both sides of a leading half of the coupling, wherein the control cage is formed with a conical surface on the end facing the tapered surface of the ring and mounted in the housing with the possibility of rotation Strongly.
