Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, 2, and 3, the upper box body structure of the reduction gearbox in the embodiment includes a box cover top plate of an inverted U-shaped structure, and a longitudinal section of the box cover top plate is a trapezoidal structural member with a narrow top and a wide bottom. And both sides of the top plate of the box cover are provided with a side plate of the input end of the box cover and a side plate of the output end of the box cover. Set up three input shaft hole on the case lid input curb plate: the input shaft hole of high-speed input, intermediate speed input shaft hole and low-speed input shaft hole, intermediate speed input shaft hole locate between high-speed input shaft hole and the low-speed input shaft hole, and the axis of three is located on same horizontal plane and is parallel to each other. The high-speed input end bearing gland is arranged on the high-speed input end shaft hole, the medium-speed input end bearing gland is arranged on the medium-speed input end shaft hole, and the low-speed input end bearing gland is arranged on the low-speed input end shaft hole. Two output end shaft holes are formed in the side plate of the output end of the box cover, and the axes of the two output end shaft holes are arranged on the same horizontal plane and are parallel to each other. The output end shaft holes are respectively covered with an output end bearing gland. The top of the top plate of the box cover is provided with a motor frame, and the motor frame is provided with a motor. The top plate of the box cover is provided with an air outlet hole which is connected with an air outlet pipe.
