Abstract

The utility model relates to an electricity loss brake of electromagnetism, which is mainly characterized in that firstly, after the internal part of a splined hole of a rotor is provided with a spring sheet through screws, the internal part of the splined hole of a rotor is provided with a splined sleeve; secondly, one side surface of through holes on both end surfaces of handles is provided with a self-locking device. Accordingly, the utility model has artful design. When power-down conditions are generated and manual release is required, the handles can conduct the self-lock, and the purpose that the handles are very conveniently released can be obtained. In addition, the utility model also has the characteristics of steady and reliable braking and reduced noise.

Description

The electromagnetism power-off brake

The utility model belongs to F16D class technology, particularly relates to a kind of electromagnetism power-off brake that is used for machine driven system.

In the at present known electromagnetism power-off brake that is used for machine driven system, though have the manual release function, when in case powering-off state occur, when needing manual release, handle can not self-locking, so the manual release operation is very inconvenient.In addition, be to be connected by tooth to form because the structure of spline housing is installed in the rotor in the break, therefore there is backlash, and is easy to generate noise.

The purpose of this utility model is to overcome the deficiency in the known technology and a kind of electromagnetism power-off brake that increases auto-lock function and significantly reduce noise is provided.

The purpose of this utility model is achieved in that

The utility model is by being shaped on two groups of through holes and one group of blind hole on the yoke body in hole being threaded, install screw by one group of through hole on the yoke body, screw passes behind the yoke body suit adjustment cover on screw, put in adjustment armature is housed, screw is installed jointing plate after passing again and adjusting cover on screw, the rotor that has splined hole is installed between armature and jointing plate, by epitrochanterian splined hole spline housing is installed, mounting spring and pin in another group through hole on the yoke body, the adjustment mother who has the flanged lip that pin is pushed down is installed by the tapped hole on the yoke body, the spring that its other end is mounted on armature is installed in the blind hole on the yoke body, by armature also symmetrical bolt that has spring that installs in the yoke body, bolt all passes the handle shaft that has been threaded behind the yoke body on the termination of bolt, on two exterior edge faces of yoke body, connect and adorn a handle, install by through hole on the both ends of the surface of handle on the basis of handle shaft composition, be to realize the purpose of this utility model like this, spline housing be installed after by screw spring sheet being installed in the splined hole of the rotor in 1. above-mentioned again; 2. on a side of through hole on the both ends of the surface of handle, be shaped on self-locking device.

The concrete linkage structure that is shaped on self-locking device on the both ends of the surface of above-mentioned handle on the side of through hole is, respectively be shaped on the side of through hole on the handle both ends of the surface with handle on the restraining groove that connects of through hole, back one section face of this side is made the arc surface concentric with the handle shaft center of circle.

The spring sheet that is equipped with in the splined hole with the rotor in above-mentioned can be made as circular shape, also can be made as the L type.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cut-away view of Fig. 1;

Fig. 3 is the right diagrammatic sketch of Fig. 1;

Fig. 4 is the left view of handle 6 among Fig. 1;

Fig. 5 is the user mode figure of handle 6 among Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

With reference to Fig. 1, Fig. 2 and Fig. 3, be shaped on two groups of through holes 19 on the yoke body 7 in hole 23 respectively being threaded, 20 and one groups of blind holes 22, install screw 3 in the through hole 19 on the yoke body, after this screw passes the other end of yoke body, suit adjustment cover 4 on screw, by adjusting cover armature 5 is installed, after screw 3 passes again and adjusts cover, on screw, be set with joining plate 2 again, the rotor 1 that has splined hole 24 is installed between above-mentioned armature and the joining plate, for preventing backlash and producing noise, therefore the spring sheet 16 of L type is installed by screw 17 in the splined hole of rotor, spline housing 15 is installed in the splined hole of rotor then, like this backlash between spline housing and rotor is extruded into a side, thereby reduce the purpose of noise when reaching spindle operation.Connect mounting spring 14 and pin 13 in the above-mentioned through hole 20 on the yoke body, by the tapped hole on the yoke body 23 the adjustment mother 8 who has flanged lip 25 is installed, the flanged lip of adjusting on the mother is pushed down pin 13.In the blind hole 22 on the yoke body spring 21 is loaded in it the other end of spring and armature top dress.State again by armature also symmetrical bolt 11 that has spring 12 that installs in the yoke body, two bolts 11 also pass the yoke body, on the bolt end that passes the yoke body all by the handle shaft 10 that has been threaded, by two exterior edge faces on the yoke body handle 6 is housed even, with reference to Fig. 4 and Fig. 5, on the handle both ends of the surface, be shaped on through hole 9, handle shaft is threaded onto in the through hole 9 on the handle, respectively be shaped on the restraining groove 18 that connects with the handle through hole on the handle on the side of both ends of the surface through hole, arc surface is made at back one section face 26 place that again this side contacted with the yoke contact level, and the center of circle of its arc surface is concentric with the center of circle of handle shaft.After above structure can make handle move several angle to, promptly toggle it in the restraining groove 18 on the handle, handle unclamps can self-locking, this be because when the surface of contact that contacts with handle with the yoke body be that basal plane is when beginning to move handle, the handle plane contacts with the yoke body, and point of contact is by yoke body center line, so realized auto-lock function.

Advantage and the good effect that the utlity model has are:

Owing in the splined hole of rotor, add spring leaf and be shaped with self-locking device at handle, therefore In a single day make the utlity model has to be skillfully constructed, and ought powering-off state occur, when needing manual release, Handle can self-locking, reaches very easily purpose of handle release. The utility model also has braking in addition Steady reliable characteristics with reducing noise.
