Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail:
Embodiment
As shown in Figure 1 and Figure 2, the brake apparatus of a kind of power transmission shaft gear transmission mechanism, including axle sleeve is the 2nd,
Power transmission shaft the 6th, axle sleeve telescopic stand 1 and gear 5, axle sleeve 2 has power transmission shaft installing hole 21, the end of power transmission shaft 6
Portion is rotatably assorted in the power transmission shaft installing hole 21 being installed on axle sleeve 2.The biography of the preferred axle sleeve of the utility model 2
Being provided with bearing in moving axis installing hole 21, the end of power transmission shaft 6 is rotatably assorted in the bearing being installed on axle sleeve 2.
As it is shown in figure 1, axle sleeve telescopic stand 1 has the telescopic cavity accommodating axle sleeve 2, axle sleeve 2 telescopic movable is pacified
Being loaded in the telescopic cavity of axle sleeve telescopic stand 1, gear 5 is fixedly installed in the power transmission shaft 6 near axle sleeve 2 side
On.The end face near gear 5 side for the axle sleeve 2 is braking installed surface, and axle sleeve 2 concaves from braking installed surface
Falling into and being provided with several electromagnet 3, electromagnet 3 is connected with the power supply outside axle sleeve 2 by drawing wire 31,
Being installed with several friction plates 4 on the braking installed surface of axle sleeve 2, gear 5 is near axle sleeve 2 side
The armature 51 of electromagnetism adhesive corresponding with electromagnet 3 is installed on end face.
As it is shown in figure 1, be provided with several between bottom the telescopic cavity of axle sleeve telescopic stand 1 and bottom axle sleeve 2
Back-moving spring 11, one end of back-moving spring 11 is connected bottom the telescopic cavity of axle sleeve telescopic stand 1, back-moving spring
The other end of 11 is connected bottom axle sleeve 2；When the electromagnet 3 in axle sleeve 2 is not with armature 51 electromagnetism adhesive,
When all back-moving springs 11 are in nature.
As in figure 2 it is shown, axle sleeve 2 is overall in positive hexagon, the telescopic cavity of axle sleeve telescopic stand 1 also mates and is
Positive hexagon.
Operation principle of the present utility model is as follows:
During normal condition, gear 5 drives other power-equipments operating being connected with gear, and power transmission shaft 6 rotates
Coordinating in the bearing being installed on axle sleeve 2, power transmission shaft 6 is rotated by motor, thus driven gear 5 is same
Step rotates, and now all back-moving springs 11 in the telescopic cavity of axle sleeve telescopic stand 1 are in nature (i.e.
Non-stretched or uncompressed), electromagnet 3 is not powered by external power source by drawing wire 31, and electromagnet 3 is not
Produce electromagnetic force, axle sleeve 2 is completely accommodated in the telescopic cavity of axle sleeve telescopic stand, friction plate 4 also not with gear 5
Armature 51 contact (i.e. the armature 51 of friction plate 4 and gear 5 is in a distance).When needs are tight
When suddenly braking other power-equipments being connected with gear, i.e. brake hard gear 5 rotates, then external power source
Being powered electromagnet 3 by drawing wire 31, electromagnet 3 produces the powerful electromagnetism attracted with armature 51
Power, under electromagnetic force, propeller shaft sleeve 2 stretches out the motion of axle sleeve telescopic stand 1 direction, then friction plate 4 with
Armature 51 is in close contact, and now all back-moving springs 11 are in drawing work state under electromagnetic force；
Due to electromagnet 3 electromagnetic attracting force armature 51 so that friction plate 4 is given and armature 51 frictional resistance effect, reaches
Purpose to rapid braking.After braking finishes, after power-equipment is immediately static, closes external power source and stop
Power for electromagnet 3, electromagnet 3 no longer electromagnetism adhesive armature 51, the elastic recovery of all back-moving springs 11
Power propeller shaft sleeve 2 is retracted in axle sleeve telescopic stand 1, such friction plate 4 just armature 51 no longer with gear 5
Contact (i.e. the armature 51 of friction plate 4 and gear 5 is in a distance), i.e. friction plate 4 no longer give with
Armature 51 frictional resistance effect, in order to restart the power-equipment being connected with gear.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,
All any modification, equivalent and improvement etc. made within spirit of the present utility model and principle, all should
It is included within protection domain of the present utility model.
