Technical Field
[0001] The utility model relates to the field of reduction motor devices, in particular to a fastened connection type reduction motor. Background Art
[0002] The reduction motor box converts the speed and torque of the motor output in real time into corresponding proportions, connects the motor device at the input end of the reduction motor box, and connects the linkage device at the output end of the reduction motor box. When the reduction motor box is connected to the linkage device, the torque output by the reduction motor may be too large, and the connection strength with the linkage device may be insufficient. Directly increasing the connection strength between the reduction motor and the linkage device (for example, using high-strength fixing bolts and nuts) may destroy the original connection (hole) position structure between the reduction motor and the linkage device. Therefore, how to enhance the connection strength between the reduction motor and the linkage device to avoid increasing the overload burden at the connection position has become a problem that needs to be solved.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0019] Embodiment 1: The present invention relates to a fastened connection type reduction motor, the main structure of which is as follows:
[0020] See also Figure 1The reduction motor includes: a motor ring shell 1, an end panel 2, a front end face 201 located on the front side of the end panel 2, and an inwardly concave structure 202 is provided on the front end face 201. The concave structure 202 has various structures such as a circular groove and a square groove, and can be customized according to the shape structure of the contact end face of the linkage device to improve the matching accuracy with the linkage device. The output bearing ring 3 of the reduction motor is located at the position of the concave structure 202, and the axis of the output bearing ring 3 is located directly above the center point of the concave structure 202. In fact, the output bearing ring is located in the upper area of the concave structure.
[0021] Assuming that the area of the front end surface 201 is Sa, the area of the concave structure 202 is Sc, and the area of the concave structure 202 includes the area occupied by the side end of the output bearing ring 3, then Sc:Sa≥60%.
[0022] See also Figure 2 , Figure 4 The rear side surface of the end panel 2 and the motor ring shell 1 are integrally connected, and a thickened corner plate 203 is arranged at the corner position of the rear side surface of the end panel 2. The thickened corner plate 203 protrudes from the rear side surface of the end panel 2. A horizontal through hole 204 is opened at the position of the thickened corner plate 203. A connecting fillet 205 is arranged at the connection position between the thickened corner plate 203 and the rear side surface of the end panel 2 and the motor ring shell 1.
[0023] See also Figure 1 , Figure 3 , a base plate 4 is fixedly provided on the bottom side of the motor ring shell 1, and the base plate 4 is integrally formed with the motor ring shell 1, and a vertical fixing screw hole 401 is provided on the bottom side of the base plate 4. Each straight through hole 204 is aligned with each other, that is, the horizontal straight through holes 204 are aligned, and the vertical straight through holes 204 are also aligned. In addition, the straight through holes 204 are vertically distributed in the longitudinal direction, and can be matched with the fixing screw holes 401 of the base plate 4 in the longitudinal position. After the fixing screw holes of the base plate 4 are bolted, the longitudinal height of the entire reduction motor may change to a certain extent. Therefore, the straight through holes 204 are vertically distributed so as to be matched with the fixed installation position of the base plate 4, so as to facilitate the installation of bolts and nuts at the positions of the straight through holes 204.
