Go out shaft end, gear wheel is packed on axle, big pinion gear engagement, traction motor driving wheel revolution, and is produced on wheel week
Raw tractive force.The driving device of integral traction motor is complex (referring to traction motor suspension), and driving device is usual
For primary gear speed reducing device, double reduction can also be used when necessary.
In existing driving device, driving pin and end cover tight fit be easy to cause the damage of sealed bottom, usually
Anti- rotary driving device in driving pin and end cover tight fit, mechanical seal drives pin to have phase with sealing ring at work
To movement, the damage of mechanical seal ring can be caused, influences whether the service life of mechanical seal.
Utility model content
The purpose of this utility model is to provide a kind of anti-rotary driving device of more stable sealing, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical solution：A kind of more stable sealing anti-rotation driving dress
It puts, it is described including axis, the first connector, fastening plates, the second connector, anti-rotation pin, end cover, throw-out collar and sealing ring
The side of axis is fixedly installed the first connector, and the outside both ends of first connector are connected with fastening plates respectively, described
It is connected with the second connector between fastening plates, the position of the inside of second connector on the inside of the first connector offers
End cover, the anti-rotation pin are slidably connected at the inside of end cover, the anti-rotation pin on the outside of end cover one
End is socketed with throw-out collar by the position of close end, and the inside of second connector is connected with sealing in the end position of anti-rotation pin
Ring.
Preferably, it is fitted close and uses between the anti-rotation pin and throw-out collar.
Preferably, it is connected with seal washer between the sealing ring and the second connector inner end.
Preferably, it is provided with hollow gap between the sealing ring and the first connector outboard end.
Preferably, it is matched between the end cover and anti-rotation pin.
Compared with prior art, the beneficial effects of the utility model are：
1st, it being used cooperatively between each other by sealing ring and throw-out collar and anti-rotation pin so that driving is firm, and operation is more stable,
Service life is long；
2nd, entire driving mechanism assembling is simple, is easily installed use；
3rd, sealing ring is more robust, increases the service life of entire driving device, economical and practical.
Description of the drawings
Fig. 1 is the utility model overall structure diagram.
In figure：1- axis；The first connectors of 2-；3- fastening plates；The second connectors of 4-；5- anti-rotation pins；6- end covers；
7- throw-out collars；8- sealing rings.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
