Description
[technical field]
The utility model relates to mechanical transmission fields, specifically, relates to a kind of torque limiter between driving and transmission device output shaft and working machine or the actuator's reach that is used to connect.
[background technique]
Generally, being connected between transmission output shaft and the external load all is that unprotect connects, and when external load is caused under the situation of abnormal operation or counter-rotating by artificial or other active force, produces excessive torque, damages driving mechanism and drive unit easily.
For example, a kind of automatic cover-turning formula toilet is arranged at present, the automatic cover-turning of this toilet is that the output shaft through a motor is connected with a bearing of toilet lid and carries out; Carry out when an opportunity arises people, the output shaft of motor rotates the bearing rotation that drives toilet lid makes toilet lid dig, still; In some cases, the people for when renovating, because accidentalia such as user's misoperation; For example; Moment digs toilet lid, depress etc., and this moment, the bearing of toilet lid and the bearing of motor still are in coupled condition; Because the people is when turning over pressure, the moment of torsion between the bearing of toilet lid and the output shaft of motor is excessive to cause transmission system (like gear etc.) and drive system (like motor) to be damaged; The above-mentioned mistake by this, in application in the majority such as daily life and commercial production, need a kind of connection protective gear to be positioned between drive system, transmission system and the external load, even can guarantee also under the torque condition that driving and transmission system are not destroyed.
[model utility content]
The purpose of the utility model is to overcome in the existing technology and drives and transmission device output shaft and external load did not have torque protection and cause damaging driving and transmission system easily and fail a kind of torque limiter that deficiency provides when being connected.
The utility model is realized through following technological scheme: a kind of torque limiter, and it comprises first transmission body, second transmission body, bolt, spring, clamping pad and nut; Said first transmission body is provided with a gear card A, and said gear card A is provided with gear disk A, and the home position place of said gear disk A is provided with a through hole A; Said second transmission body is provided with a gear card B, and said gear card B is provided with and is suitable for and said gear disk A meshed gears dish B, and the home position place of said gear disk B is provided with a through hole B; Said clamping pad be provided with a through hole C; The gear disk A of said first transmission body and the gear disk B of said second transmission body are meshing with each other, and the through hole C of the through hole A of said screw bolt passes first transmission body, through hole B, spring and the clamping pad of second transmission body is pressed on spring between second transmission body and the clamping pad through cooperating with said nut.
Do further to set forth in the face of above technological scheme down:
Further; Said second transmission body also is provided with the driving protection shell of a tubular; The lower end surface of said driving protection shell is arranged at the reverse side of gear card B, and an end, spring, clamping pad and the nut of said bolt thread end is wrapped in the said driving protection shell.
Further, the head of said bolt is provided with a draw-in groove.
Further, the upper-end surface of said driving protection shell is provided with a plurality of grooves.
The beneficial effect of the utility model is: the torque limiter of this structure is arranged between the reach of output shaft and external load of transmission device as a kind of connector element; Specifically; The output shaft of transmission device is connected with first transmission body of this structure; The reach of external load is connected with second transmission body of this structure,, drives the reach rotation of external load again through this torque limiter through this torque limiter of output shaft drive of transmission device; If external load takes place unusual, when surpassing rated torque, the gear disk A of first transmission body and the gear disk B of second transmission body will slide, and cut off the reverse transmission of excessive load moment of torsion to the transmission device output shaft; By this, transmission and drive unit can be damaged because of crossing moment of torsion, play a protective role.

[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described:
With reference to Fig. 1 and shown in Figure 2, a kind of torque limiter that this model utility discloses, it comprises first transmission body 1, second transmission body 2, bolt 3, spring 4, clamping pad 5 and nut 6; Said first transmission body 1 is provided with a gear card A, and said gear card A is provided with gear disk A11, and the home position place of said gear disk A11 is provided with a through hole A; With reference to shown in Figure 3; Said second transmission body 2 is provided with a gear card B; Said gear card B is provided with and is suitable for and said gear disk A11 meshed gears dish B21; The home position place of said gear disk B21 is provided with a through hole B, and said second transmission body 2 also is provided with the driving protection shell 22 of a tubular, and the lower end surface of said driving protection shell 22 is arranged at the reverse side of gear card B; Said clamping pad 5 be provided with a through hole C; The gear disk B21 of the gear disk A11 of said first transmission body 1 and said second transmission body 2 is meshing with each other, and the through hole C of through hole B, spring 4 and clamping pad 5 that said bolt 3 passes through hole A, second transmission body 2 of first transmission body 1 successively is pressed on spring 4 between second transmission body 2 and the clamping pad 5 through cooperating with said nut 6; One end of said bolt 3 threaded end, spring 4, clamping pad 5 and nut 6 are wrapped in the said driving protection shell 22.In addition, the head of said bolt 3 is provided with a draw-in groove.The upper-end surface of said driving protection shell 22 evenly is provided with four grooves.
