Description

Technical Field

[0001] The utility model belongs to the technical field of motor regulation, and relates to a motor base and a speed reduction motor thereof. Background Technique

[0002] The motor base is generally installed at the bottom of the motor, playing a role in supporting and fixing the motor. The motor base can effectively support the stator core and coil, thereby ensuring the stable operation of the motor.

[0003] Chinese Patent No. CN205544704U discloses a general-purpose motor mounting base, including a bottom plate and two strip-shaped support plates arranged in parallel on the bottom plate. The tops of the two strip-shaped support plates are provided with two strip-shaped grooves opposite to and adapted to the bottom buckle of the motor. Four strip-shaped mounting holes are provided on the bottom plate along the length direction, and these strip-shaped mounting holes are opposite to each other in pairs.

[0004] It can be seen from the specification drawings and the specification provided by this patent that a general-purpose motor mounting base provided by this patent is connected to the bottom of the motor through the groove and supported by the strip-shaped support plates. However, the structure of the strip-shaped support plates is a 90° right-angle structure, and the damping effect is not good during use. Moreover, due to the groove connection structure, there is a problem of easy loosening when subjected to vibration. Content of the Utility Model

[0006] The purpose of the utility model can be achieved by the following technical solutions: A motor base and a speed reduction motor thereof, including a motor base, a driving motor, and a speed reducer. The motor base is fixedly installed at the bottom of the driving motor. The motor base includes a first-layer bottom plate and a second-layer support plate. The first-layer bottom plate is provided with a first weight-reducing hole and a second weight-reducing hole. An arc-shaped support rod is formed around the first weight-reducing hole, and the arc-shaped support rod is fixedly connected to the bottom of the second-layer support plate. A third weight-reducing hole is provided at the center of the second-layer support plate. Connecting plates extend from both sides of the second-layer support plate. Connecting holes are provided on the connecting plates. A motor connecting foot is fixed at the bottom of the driving motor. The motor connecting foot is fitted and installed with the connecting plate. A fastening bolt is fixedly connected between the motor connecting foot and the connecting plate. The speed reducer is fixedly installed on one side of the first-layer bottom plate. A motor shaft extends from the driving motor. A coupling is fixedly connected to one side of the speed reducer, and the coupling is connected to the motor shaft.

[0007] In the above-mentioned motor base and speed reduction motor, the number of the arc-shaped support rods is four, and the arc directions of the arc-shaped support rods all face the center of the first weight-reducing hole.

[0008] In the above-mentioned motor base and its reduction motor, a number of limiting grooves are provided on both sides of the first layer of bottom plate.

[0009] In the above-mentioned motor base and its reduction motor, the height of the connecting plate is higher than that of the second layer of support plate.

[0010] In the above-mentioned motor base and its reduction motor, the front side of the first layer of bottom plate is an inclined block, and the reducer is fixedly installed on the inclined block.

[0011] Compared with the prior art, the motor base and its reduction motor provided by the present utility model have the following beneficial effects: 1. Through the structural setting of the arc-shaped support rod, the arc-shaped structure is beneficial to reducing impact and dynamic deformation, and improving the stability of the motor base; 2. By setting the first weight-reducing hole and the second weight-reducing hole on the first layer of bottom plate, and setting the third weight-reducing hole on the second layer of support plate, the weight of the motor base is effectively reduced, and the production cost is reduced.

[0015] The following are specific embodiments of the present utility model and in combination with the drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0016] Such as Figures 1 to 2As shown in the figure, this embodiment includes a motor base 1, a driving motor 2, and a reducer 3. The motor base 1 includes a first-layer bottom plate 11 and a second-layer support plate 12. The second-layer support plate 12 is located above the first-layer bottom plate 11. The number of arc-shaped support rods 13 is four, and the arc-shaped support rods 13 are welded and fixed between the first-layer bottom plate 11 and the second-layer support plate 12. A through first weight-reducing hole 111 and a second weight-reducing hole 112 are provided on the first-layer bottom plate 11. A through third weight-reducing hole 121 is provided at the center of the second-layer support plate 12. Two symmetrically arranged connecting plates 14 extend from both sides of the second-layer support plate 12. Connecting holes 141 are provided on the connecting plates 14. The bottom of the driving motor 2 is provided with motor connecting feet 21 that expand outward on both sides. The height of the connecting plates 14 is higher than that of the second-layer support plate 12. This structure leaves a gap between the second-layer support plate 12 and the bottom of the driving motor 2. The two motor connecting feet 21 are fitted and installed with the two connecting plates 14. A fastening bolt 4 passes through the motor connecting feet 21 and the connecting plates 14 and fixes the motor connecting feet 21 and the connecting plates 14. The driving motor 2 extends out a motor shaft 22. One side of the reducer 3 is fixedly connected with a coupling 5, and the coupling 5 is connected with the motor shaft 22.

[0017] Specifically, as Figures 1 to 2 shown, the area of the first weight-reducing hole 111 is larger than that of the second weight-reducing hole 112. The second weight-reducing hole 112 is located on the first-layer bottom plate 11 between the driving motor 2 and the reducer 3.

[0018] Further elaborating, as Figures 1 to 2 shown, the arc-shaped support rods 13 are located around the first weight-reducing hole. The arcs of the arc-shaped support rods 13 all face the center of the first weight-reducing hole 111. A fan-shaped hole is formed between every two arc-shaped support rods 13 and the first-layer bottom plate 11 and the second-layer support plate 12.

[0019] Further elaborating, as Figures 1 to 2 shown, a number of limiting grooves 113 are provided on both sides of the first-layer bottom plate 11. The limiting grooves 113 enable the motor base 1 to be fixedly installed with other instruments. The front side of the first-layer bottom plate 11 is an inclined block 114. The inclined block 114 protrudes from the first-layer bottom plate 11. The reducer 3 is fixedly installed on the inclined block 114. This structure enables the reducer 3 and the motor shaft 22 of the driving motor 2 to be on the same horizontal axis. The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
