Abstract
The utility model discloses a kind of locking output mechanism, comprise output shaft 1, collar 2, locking nut 3, earrings assembly 4, output shaft 1 adopts with earrings assembly 4 and is threaded.A kind of locking output mechanism delicate structure of the present utility model, to be coordinated with locking nut 3 by the boss structure on collar 2 and realizes locking function, can ensure that earrings connects and not loosen, have structure simple, be easy to the feature of processing.
Description
Technical field
The utility model relates to a kind of mechanical output mechanism, is specifically related to the locking output mechanism of a kind of delicate structure, reliable lock.
Background technique
In tradition output mechanism, earrings assembly locking mode is nut check, this locking mode has its shortcoming as follows: be subject to foeign element as under vibration, impact, variable load and thermal stress effect, loosening easily appears in the connection of nut and mating parts, earrings can be caused to connect loosening, fastening strength reduction, even cause damage.
Model utility content
The purpose of this utility model is: in order to overcome the deficiency of existing output mechanism locking mode, the utility model adopts the locking output mechanism of a kind of delicate structure, reliable lock.
The technical solution of the utility model is: a kind of locking output mechanism, comprise output shaft 1, collar 2, locking nut 3, earrings assembly 4, output shaft 1 adopts with earrings assembly 4 and is threaded, collar 2 and locking nut 3 are enclosed within earrings assembly axle, earrings assembly 4 axle is provided with the rectangle groove identical with reach, output shaft 1 end face boss is provided with two keyways of 180 degree of symmetries, collar 2 end face is provided with two boss of 180 degree of symmetries, coordinate with two keyways of output shaft, collar 2 inner ring is provided with a boss, coordinate with the rectangle groove on earrings assembly 4 axle, collar 2 inner ring is unthreaded hole, outer ring is provided with insurance hole, locking nut 3 is provided with insurance hole.
Preferably, the outer ring of collar 2 is provided with insurance hole.Locking nut 3 is provided with insurance hole.
Advantage of the present utility model is: a kind of locking output mechanism of the present utility model, collar is added between locking nut and output shaft, coordinate spacing by the boss of collar end face and inner ring with output shaft, earrings assembly, effectively prevent locking nut loosening and losing efficacy under extraneous complicated environmental condition, thus avoid loosening and rotating of earrings assembly, ensure that join strength and the reliability of output mechanism, simultaneously, mechanism structure is simple, be easy to manufacturing, be conducive to batch production and promote the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of locking output mechanism of the utility model.
Fig. 2 is the Spring Clip schematic diagram in the utility model.
Embodiment
Below the utility model is described in further details.See Fig. 1 and Fig. 2, a kind of output mechanism with shrinking device, comprise output shaft 1, collar 2, tightening nut 3, earrings assembly 4, output shaft 1 adopts with earrings assembly 4 and is threaded, first collar 2 and locking nut 3 are enclosed within earrings assembly axle during assembling, square key slot fit on the boss of collar 2 inner ring and earrings assembly 4 axle, can ensure that earrings assembly 4, with output shaft 1, relative rotation does not occur when collar is locked, earrings assembly 4 is connected with output shaft 1 by neutral length as required, after determining meta, two symmetrical boss of collar 2 end face are coordinated with the corresponding rectangle groove of output shaft 1 end face, screw locking nut 3, collar 2 outer ring and locking nut 3 are equipped with insurance hole, insurance is played fixing between collar 2 and locking nut 3, can ensure to lock rear collar 2 and nut 3 realization interlocking, thus ensure that the reliability that whole mechanism connects.
