Abstract
The utility model discloses an electric traction driving device. The electric traction driving device comprises a driving motor, wherein the driving motor is connected with a worm; one side of the motor is provided with a chassis; the worm extends into the chassis; the chassis is internally provided with a plurality of worm wheels; wheel faces of the worm wheels are uniformly adhered to the worm; a rotating shaft for synchronous rotation is arranged in the middle of each worm wheel; and one end of the worm is provided with a hand joint. The electric traction driving device avoids the driving disadvantages of an existing motor, and is designed to be a motor driving device which circles around building stairs and circularly drives in an up-and-down running manner. According to the device, the plurality of worm wheels are synchronously driven and rotated by the same worm, thus ensuring synchronous concordance among the plurality of worm wheels; and moreover, the starting is stable, the running is stable when objects and people are carried, and the safety reliability is extremely high.
Description
Technical field
The utility model relates to a kind of Power Drive Unit, particularly a kind of electric traction driving device.
Background technique
More common motor cycle drive unit in the market, one motorcycle endless chain drive unit, on structural design, chain is driven by sprocket wheel and rotates, and sprocket wheel is by the engine shaft driven rotary, the 2nd, and bicycle chain drives assembling structure, and the common ground of the two all is that circulation drives, the place of its deficiency is to realize that the multistage fantasy that spirals drives, and can't realize that particularly building moves up and down along the loading of spiraling of stair case, manned circulation.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of electric traction driving device that drives for loading, manned circulation.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of electric traction driving device, comprise drive motor, be connected with a worm screw on the described drive motor, one side of described motor is provided with cabinet, worm screw stretches in the cabinet, is provided with a plurality of worm gears in the described cabinet, and the wheel face of described turbine all is bonded on the worm screw, the centre of described each worm gear is provided with a transmission shaft that rotates synchronously, and the end of described worm screw is provided with hand joint.
As further improvement of the utility model, be provided with 3 worm gears in the described cabinet, described 3 worm gears are the setting of " product " font, and wherein the top of worm screw is provided with a worm gear, and the below of worm screw is provided with two worm gears.
As further improvement of the utility model, described drive motor is reducing motor.
The beneficial effects of the utility model are: the utility model is avoided existing motor-driven deficiency, be intended to design around the building spiral stair motor drive unit that upper and lower operation drives that circulates, this device rotates by same a plurality of worm gears with the worm screw synchronous drive, guaranteed the synchronous conformity between a plurality of worm gears, and start steadily, loading is manned operates steadily, safety reliability is high, guaranteed that the transmission shaft traction power passes to extraneous mechanism perfectly safely, fundamentally stopped the phenomenon that the integral device driving wheel skids.
