The utility model adopts the technical proposal that: the utility model provides a be used for driving speed reducer that drives a vehicle which characterized in that: the bevel gear mechanism comprises a box body, a blind cover plate, a motor bracket, a bearing seat, a bevel gear shaft, a bevel gear, a middle first shaft, a gear set, a middle second shaft, a middle third shaft and a hollow output shaft, wherein the middle first shaft, the middle second shaft and the middle third shaft are connected in parallel in a penetrating way up and down in the box body and are packaged by a left blind cover plate and a right blind cover plate; the box body is a hollow box body filled with water, the bottom of the hollow box body is connected with a water drain plug screw connected with the hollow box body and an oil drain plug screw connected with the inner cavity of the box body, and the side edge of the upper part of the box body is provided with a water inlet plug screw connected with the hollow box body.
An oil seal is arranged between the transparent cover and the hollow shaft.
The bearing seat is internally provided with a double-row tapered roller bearing, the lower end of the double-row tapered roller bearing is supported on an inner step of the bearing seat, the upper end of the double-row tapered roller bearing is screwed on a cone gear shaft through a round nut and is pressed through a stop washer, and the bearing seat is packaged through a transparent cover penetrating through the cone gear shaft.
An oil seal is arranged between the transparent cover and the bevel gear shaft.
The two sides of the upper part of the box body are connected with the extending lifting lugs.
The bevel gear shaft is connected with power through a coupler arranged in the motor support.
The utility model adopts the bearing seat to support the bearing and tightly press the bearing through the round nut, thereby realizing firm positioning of the bevel gear shaft with power input and stable power input; and to the hollow structure of box through the screw plug that intakes water cooling speed reducer that intakes, the screw plug that drains in the bottom discharges, satisfies the speed reducer cooling requirement of driving drive for a long time, has that the cooling is effectual, increase of service life's advantage.
