Description
Technical field
The utility model relates to a kind of stopper mechanism, is specifically related to a kind of break brake-loosing mechanism.
Background technique
In the design of the manual brake-loosing mechanism of break, usually adopt multiple assembly, or the position of double nut lock nut, not easily, constructional appearance is poor in assembly processing.Due to without thrust bearing, when manually declutching, produce friction between double nut and Runner assembly, declutch difficulty, and need to be equipped with the extra spanner that declutches, and cost is large, and the flexibility of mechanism is not high yet.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of break brake-loosing mechanism, adopts standard piece, and structure is simple, adopts thrust ball bearing, and reduce the friction between component, practicability is high.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of break brake-loosing mechanism, comprises the bar that declutches, the extrusion barrel of being fixed by elastic cylindrical pin and the described bar that declutches, bolt, steel ball, and break moves plate, the quiet plate of break; Described break moves plate, the quiet plate of described break and described extrusion barrel successively through described bolt, described steel ball is arranged between the quiet plate of described break and described extrusion barrel, also comprise thrust ball bearing, shaft end ring and set screw, it is inner that described thrust ball bearing is arranged on described extrusion barrel, described bolt is through described thrust ball bearing, there is tapped hole at the center, end of described bolt, described set screw passes described shaft end ring and pierces in described tapped hole, and described shaft end ring and described extrusion barrel form enclosed space.
Further, described thrust ball bearing fixes its axial position on described bolt by locking nut.
The beneficial effects of the utility model are:
The utility model many employings standard piece, structure is simple, adopts thrust ball bearing, decrease the friction between component, mechanism action is flexible, and can be used for variously needs the break of hand release and clutch and with all kinds of fixtures of break same principle, practicability is high.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram at A place in Fig. 1.
Number in the figure illustrates:
1, declutch bar, and 2, elastic cylindrical pin, 3, extrusion barrel, 4, shaft end ring, 5, set screw, 6, locking nut, 7, thrust ball bearing, 8, steel ball, 9, bolt, 10, break moves plate, 11, the quiet plate of break.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1, Fig. 2, a kind of break brake-loosing mechanism, comprises the bar 1 that declutches, by the extrusion barrel 3 that elastic cylindrical pin 2 is fixing with the described bar 1 that declutches, bolt 9, and steel ball 8, break moves plate 10, the quiet plate 11 of break; Described break moves plate 10, the quiet plate of described break 11 and described extrusion barrel 3 successively through described bolt 9, described steel ball 8 is arranged between the quiet plate of described break 11 and described extrusion barrel 3, also comprise thrust ball bearing 7, shaft end ring 4 and set screw 5, it is inner that described thrust ball bearing 7 is arranged on described extrusion barrel 3, described bolt 9 is through described thrust ball bearing 7, there is tapped hole at the center, end of described bolt 9, described set screw 5 passes described shaft end ring 4 and pierces in described tapped hole, and described shaft end ring 4 forms enclosed space with described extrusion barrel 3.
Further, described thrust ball bearing 7 fixes its axial position on described bolt 9 by locking nut 6.
Operating principle of the present utility model: declutch described in along the circumferential direction pulling bar 1, the described bar 1 that declutches drives described extrusion barrel 3 along the circumferential direction to rotate, the end of described extrusion barrel 3 has inclined-plane to be close to described steel ball 8, time described extrusion barrel 3 is rotated, inclined-plane extrudes described steel ball 8, the pulling force produced, described break is pulled to move plate 10, close to described break quiet plate 11, in described extrusion barrel 3 rotation process, the seat ring on the left of described thrust ball bearing 7 and bearing ball is driven to rotate, and blowout patche keeps static on the right side of described thrust ball bearing 7, described locking nut 6 and described bolt 9 is made to keep original position, the transfer phenomenon that rubs can not be there is.
The foregoing is only the preferred embodiment of model utility, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
