Background technique
In electrical power distribution apparatus killer switch, it often may require that and use a kind of motor-operating mechanism with bidirectional clutch, Such operating mechanism purposes is that motor is generally used to drive deceleration mechanism output torque or power, control when control circuit does not power off Breaker on/off switch operation processed.But for a kind of special motor-operating mechanism, it not only needs two-way clutch, but also needs in electricity Machine carries out clutch when working at any time, currently, existing bidirectional clutch is unable to satisfy its requirement.
Utility model content
It is existing to solve the purpose of this utility model is to provide a kind of bidirectional clutch device for motor-operating mechanism For the above problem existing for the bidirectional clutch of motor-operating mechanism in technology.
For this purpose, the utility model uses following technical scheme:
A kind of bidirectional clutch device for motor-operating mechanism comprising output shaft, clutch shaft, several needle rollers and from Gear is closed, the clutch gear is meshed with the speed reduction gear box of motor-operating mechanism, and the output shaft is using open at one end Hollow shaft, the clutch shaft are installed in the output shaft, and offer several on the side wall of the same circumference of the output shaft Needle roller pilot hole, the needle roller can be movably installed in needle roller pilot hole outward, and the clutch gear is set to described defeated Shaft is outer and its inner hole in be provided with groove for blocking needle roller, the clutch shaft is connected with clutch driving unit, when transmission, The clutch driving unit driving clutch shaft pushes needle roller, and movement is stuck in groove outward, and clutch gear is driven defeated by needle roller Shaft rotation, when separation, the clutch driving unit drives clutch shaft return, and needle roller and groove are detached from, and output shaft stops operating.
Particularly, the clutch driving unit uses electromagnet, and the mandril of the electromagnet is connected with the clutch shaft.
Particularly, the clutch driving unit uses electromagnet, one end of the mandril of the electromagnet and the clutch shaft It is correspondingly arranged, the reset spring resetted for clutch shaft is installed in the output shaft of the clutch shaft other end.
Particularly, the clutch shaft includes the first cylindrical section and the second cylindrical section, and the radius of first cylindrical section is less than The radius of second cylindrical section, when transmission, the position that second cylindrical section is in corresponding needle roller simultaneously pushes needle roller to move outward It is stuck in groove, when separation, the position that first cylindrical section is in corresponding needle roller limits needle roller in inside.
Particularly, the clutch shaft further includes the third cylindrical section to connect with the second cylindrical section, the third cylindrical section Radius be greater than the second cylindrical section radius, and the third cylindrical section radius cooperation output shaft internal bore radius setting, when from It play the guiding role when sympodium moves in output shaft.
The beneficial effects of the utility model are that the two-way clutch for motor-operating mechanism fills compared with prior art Set the two-way clutch that can not only realize motor-operating mechanism;And can the clutch at any time in the motor course of work, design is skilful Wonderful, stable and reliable operation is highly-safe.

Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 to Fig. 6, in the present embodiment, a kind of bidirectional clutch device for motor-operating mechanism includes Output shaft 1,2, two needle rollers 3 of clutch shaft, clutch gear 4 and reset spring 5, the deceleration of clutch gear 4 and motor-operating mechanism Case gear 6 is meshed, and speed reduction gear box 6 is driven by motor 7, and output shaft 1 uses hollow shaft open at one end, and clutch shaft 2 is pacified At the top of 1 inner hole of output shaft, one end of output shaft 1 is equipped with electromagnet 8, the mandril 9 of electromagnet 8 and one end of clutch shaft 2 It is correspondingly arranged, electromagnet 8 pushes clutch shaft 2 to move in output shaft 1 by mandril 8, and complex spring 5 is set in output shaft 1 Hole bottom is used for the reset of clutch shaft 2.
Needle roller pilot hole 10 there are two symmetrically opening up on the side wall of the same circumference of output shaft 1, needle roller 3 can outward movably It is installed in needle roller pilot hole 10, clutch gear 4 is set to output shaft 1 outside and uniformly there are four for blocking needle roller in its inner hole 3 groove 11, clutch shaft 2 include the first cylindrical section 20, the second cylindrical section 21 and third cylindrical section 22, and the half of the first cylindrical section 20 Diameter less than the second cylindrical section 21 radius, when transmission, the second cylindrical section 21 be in the position of corresponding needle roller 3 and push needle roller 3 to Outside movement is stuck in groove 11, and when separation, the position that the first cylindrical section 20 is in corresponding needle roller 3 cannot because its radius is smaller It pushes needle roller 3 to move outward, but needle roller 3 can be limited in inside, prevent needle roller 3 from taking off out of needle roller pilot hole 10 It falls.The radius of third cylindrical section 22 is greater than the radius of the second cylindrical section 21, and the radius of third cylindrical section 22 cooperates output shaft 1 Internal bore radius setting, play the guiding role when clutch shaft 2 moves in 1 inner hole of output shaft.
When transmission, 7 normal power-up of motor, motor 7 drives speed reduction gear box 6 to rotate, and speed reduction gear box 6 drives clutch Gear 4 rotates, and electromagnet 8 is powered at this time, and the ejection of mandril 9 of electromagnet 8 drives clutch shaft 2 to move down, and the second of clutch shaft 2 Cylindrical section 21 will push needle roller 3 and move and be stuck in groove 11 outward, and clutch gear 4 drives 1 turn of output shaft by needle roller 3 Dynamic, when separation, electromagnet 8 is powered off, and the mandril 9 of electromagnet 8 retracts, and reset spring 5 gets on the rebound of clutch shaft 2, is made first round Shell of column 20 is in the position of corresponding needle roller 3, at this time needle roller 3 just with the disengaging of groove 11, clutch gear 4 can not by needle roller 3 with Output shaft 1 rotates.
The above-mentioned bidirectional clutch device for motor-operating mechanism is controlled by electromagnet 8, no matter motor 7 whether work Make, it is only necessary to which logical close for controlling electromagnet 8 can control clutch at any time, can not only make electricity behaviour's two-way clutch, but also can be in motor work Clutch can be switched in making at any time.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned example Limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these changes Change and change is fallen within the scope of the claimed invention.The utility model requires protection scope is wanted by appended right Ask book and its equivalent thereof.
