Abstract
A kind of clutch gear protection device, solves the problem of broken teeth in clutch rotation process, connects stage clip, output gear, gear shaft including input gear, gear；Input gear and output gear connect stage clip by gear and connect, and input gear, output gear, gear connect stage clip three's concentric locking collar and be contained on gear shaft；Distance between described input gear and output gear is connected the length under stage clip naturalness less than described gear, thus it is that its two ends produce frictional force with input gear and output gear respectively under oppression state that gear connects stage clip, under normal condition when input gear rotates, described gear connects the frictional force at stage clip two ends and drives described output gear to rotate together, under abnormal condition i.e. in the case of output gear is stuck due to a variety of causes, the frictional force that gear connects stage clip is not enough so that output gear rotates, input gear dallies, thus protect electric machine assembly, the simple production of this apparatus structure is convenient.
Description
Technical field
This utility model relates to electronic lock field, particularly to a kind of clutch gear protection device.
Background technology
At present, all kinds of door lock electronic lock diverse in function on market, electronic lock body needs electronic section to control mechanical movement, mechanical part realizes locking a door action, and during this, electric motor clutch parts are the vitals of electronics and mechanical bond, it mainly includes motor, gear, need when motor runs well to be exported by the power of motor by pinion rotation, but turn motionless when gear meets obstructions during engagement output, the phenomenon of broken teeth will occur.
Utility model content
The purpose of this utility model solves the problem of broken teeth in the clutch rotation process mentioned in background technology, i.e. a kind of clutch gear protection device.
For achieving the above object, this utility model have employed following technical scheme:
A kind of clutch gear protection device, connects stage clip, output gear, gear shaft including input gear, gear；Input gear and output gear connect stage clip by gear and connect, and input gear, output gear, gear connect stage clip three's concentric locking collar and be contained on gear shaft；Restricted input gear and the structure of the axial displacement of output gear on described gear shaft；Distance between described input gear and output gear is connected the length under stage clip naturalness less than described gear; thus it is that its two ends produce frictional force with input gear and output gear respectively under oppression state that gear connects stage clip; under normal condition when input gear rotates; described gear connects the frictional force at stage clip two ends and drives described output gear to rotate together; under abnormal condition i.e. in the case of output gear is stuck due to a variety of causes; the frictional force that gear connects stage clip is not enough so that output gear rotates; input gear dallies, thus protects electric machine assembly.
Preferably, described gear shaft includes that interior axle and outer shaft, described interior axle are pin gear axle, and the two ends of described outer shaft connect input gear, output gear respectively and limit the axial displacement of input gear, output gear.
Preferably, on described outer shaft, there is block one end, and described input gear has the rib offseted with block, and described block limits rib and moves up；
Preferably, in order to easy to assembly, described outer shaft has cannelure, can be with mounting clip pieces in described cannelure, described fastener is spacing to output gear, limits output gear and moves down.
Owing to have employed said structure, during electric machine rotation, if the power that clutch runs into outer powershift gear passes when do not go out, input gear dallies, thus protects clutch component.
Accompanying drawing explanation
Fig. 1 is that this utility model assembles schematic diagram；
Reference is as follows: input gear 1, gear connect stage clip 2, output gear 3, gear shaft 4, interior axle 41, outer shaft 42, block 421, rib 11, draw-in groove 422.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
A kind of clutch gear protection device, connects stage clip 2, output gear 3, gear shaft 4 including input gear 1, gear；Input gear 1 and output gear 3 connect stage clip 2 by gear and connect, and input gear 1, output gear 3, gear connect stage clip 2 three's concentric locking collar and be contained on gear shaft 4；Gear shaft 4 includes interior axle 41 and outer shaft 42, and described interior axle 41 is pin gear axle, and the two ends of described outer shaft 42 connect input gear 1, output gear 3 respectively and limit the axial displacement of input gear 1, output gear 3；On outer shaft 42, there is block 421 one end, described input gear 1 has the rib 11 offseted with block 421, described block 421 limit rib 11 and move up；In order to easy to assembly, draw-in groove 422 is had on described outer shaft 42, can be with mounting clip pieces in draw-in groove 422, described fastener is spacing to output gear 3, the distance that restriction output gear 3 moves down between input gear 1 with output gear 3 is connected the length under stage clip 2 naturalness less than described gear, thus it is that its two ends produce frictional force with input gear 1 and output gear 3 respectively under oppression state that gear connects stage clip 2, under normal condition when input gear 1 rotates, described gear connects the frictional force at stage clip 2 two ends and drives described output gear 3 to rotate together, under abnormal condition i.e. in the case of output gear 3 is stuck due to a variety of causes, the frictional force that gear connects stage clip 2 is not enough so that output gear 3 rotates, input gear 1 dallies, thus protect electric machine assembly.
Claims (4)
1.A kind of clutch gear protection device, is characterised by including that input gear, gear connect stage clip, output gear, gear shaft；Input gear and output gear connect stage clip by gear and connect, and input gear, output gear, gear connect stage clip three's concentric locking collar and be contained on gear shaft；Distance between described input gear and output gear is connected the length under stage clip naturalness less than described gear; thus it is that its two ends produce frictional force with input gear and output gear respectively under oppression state that gear connects stage clip; under normal condition when input gear rotates; described gear connects the frictional force at stage clip two ends and drives described output gear to rotate together; under abnormal condition i.e. in the case of output gear is stuck due to a variety of causes; the frictional force that gear connects stage clip is not enough so that output gear rotates; input gear dallies, thus protects electric machine assembly.
