Abstract
Description
Technical Field
[0001] This utility model belongs to the field of geared motor technology, and specifically relates to a geared motor that is stable in connection and easy to disassemble and assemble. Background Technology
[0002] Gear motors are widely used in industry. Their structure mainly consists of two parts: a motor and a reducer. The motor generates a rotating magnetic field around the coil by passing current, which interacts with the magnetic field of the stationary part, causing the rotor to start rotating. The reducer reduces the output speed of the motor to the required level through gears or transmission devices, while increasing the output torque. The connection structure between the motor and the reducer is crucial and directly affects the operating efficiency and stability of the system.
[0003] In existing technologies, the motor and reducer of a geared motor are typically connected by a direct connection or a flange connection. After prolonged use, wear easily occurs at the connection point, leading to reduced connection strength, decreased stability, and the generation of vibration and noise. According to patent application number CN202222406906.6, a novel geared motor designed for easy disassembly and separation includes a fixed mounting base. A connecting seat is fixedly mounted on one end of the fixed mounting base, and the motor is fixedly mounted in a mounting hole at one end of the connecting seat. The fixed mounting base is used to improve the working stability of the geared motor. However, this patented fixed mounting base merely further strengthens the flange connection, and its effect on maintaining the stable operation of the geared motor is relatively limited. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a geared motor that offers stable connection and is easy to assemble and disassemble.
[0005] The purpose of this utility model can be achieved through the following technical solution: a geared motor that is stable in connection and easy to disassemble and assemble, comprising, in sequence, a gear reducer, a connecting end cover, a motor mounting base and a motor body;
[0006] The motor mounting base mainly includes a mounting base, which is a semi-open cylindrical structure with its opening facing the connecting end cover. The internal center of the cylindrical structure is coaxial with the mounting base to form a mounting base bushing. A square mounting base flange extends from the outer edge of the opening side of the mounting base. The mounting base flange has through mounting base screw holes at all four corners. The motor body is mounted and connected to the mounting base on the other side by motor fixing screws, and a mounting base for placing the motor body is integrally formed at the bottom.
[0007] The connecting end cover consists of an integrally formed square end cover flange and a cross flange. The connecting end cover has an eccentric bushing hole at an off-center position. Each of the four corners of the end cover flange has a first screw hole pointing from the connecting end cover to the motor mounting base. A mounting base fixing screw is installed in the first screw hole to fix the connecting end cover to the motor mounting base. Each of the cross flanges has a second screw hole at the end of the cross pointing from the connecting end cover to the gear reducer. A reducer fixing screw is installed in the second screw hole to fix the connecting end cover to the gear reducer.
[0008] In the aforementioned geared motor that is stable in connection and easy to disassemble, a number of heat dissipation holes are provided on the cylindrical outer wall of the mounting base.
[0009] In the aforementioned geared motor with stable connection and easy disassembly, the top of the base has strip-shaped motor positioning plates on both sides to accommodate the installation of the motor body. Semi-open quick-connect holes for the feet are opened on both sides of the two motor positioning plates on the base. Several sheet-shaped base support frames are evenly formed at the bottom of the base.
[0010] In the aforementioned geared motor with stable connection and easy disassembly, a shock-absorbing foot is snapped into the quick-connect hole of the foot. The shock-absorbing foot is made of a shock-absorbing material with good elasticity and energy absorption properties, preferably a rubber material.
[0011] In the aforementioned geared motor with stable connection and easy disassembly, the eccentric bushing hole has a plum blossom-shaped opening at one end facing the motor mounting base, and a bushing baffle is formed on the inner sidewall of the eccentric bushing hole.
[0012] In the aforementioned geared motor with stable connection and easy disassembly and assembly, the working shaft of the motor body is connected to the gear shaft of the gear reducer by a coupling. During installation, the coupling is located in the bushing space formed by the base bushing and the eccentric bushing hole.
[0013] Compared with the prior art, the geared motor provided by this utility model, which has stable connection and is easy to disassemble and assemble, has the following advantages:
[0014] 1. By setting a motor mounting base and connecting end cover that cooperate with each other between the motor body and the gear reducer, the end face wear caused by direct connection between the two is avoided, the service life of the geared motor is extended, and different specifications of motor body and gear reducer can be selected for mutual connection according to the actual needs of the geared motor, making it more practical.
[0015] Second, by setting a base and quick-connect shock-absorbing feet on the motor mounting bracket, the support stability and shock absorption effect of the geared motor during operation can be improved, thereby reducing the vibration and noise generated during operation.

Detailed Implementation
[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] like Figures 1 to 3 As shown, this geared motor, which has a stable connection and is easy to disassemble and assemble, is sequentially connected to a gear reducer 320, a connecting end cover 200, a motor mounting base 100, and a motor body 310. The working shaft of the motor body 310 is connected to the driven shaft of the gear reducer 320 via a coupling 330.
[0022] like Figures 2 to 3 As shown, the motor mounting base 100 mainly includes a mounting base 110. The mounting base 110 is a semi-open cylindrical structure with its opening facing the connecting end cover 200. The inner center of the cylindrical structure is coaxial with it to form a mounting base sleeve 111. The center of the mounting base sleeve 111 is through which a coupling 330 is installed to provide dust protection during operation. Several mounting base heat dissipation holes 112 are opened on the outer cylindrical wall of the mounting base 110 for heat dissipation during the operation of the geared motor.
[0023] The mounting base 110 extends from the outer edge of the opening side to form a square mounting flange 120, and the mounting flange 120 has through mounting screw holes 121 at each of the four corners. The mounting base 110 has screw holes on the hollow sealing plate on the other side, and the motor mounting base 100 and the motor body 310 are fixedly connected by motor fixing screws 113 passing through the mounting base 110 to the working end face of the motor body 310.
[0024] The mounting base 110 has an integrally formed base 130 at the bottom of the perforated sealing plate, which holds the motor body 310. To accommodate the installation of the motor body 310, the top of the base 130 has strip-shaped motor positioning plates 131 on both sides. Semi-open quick-connect holes 132 are provided on both sides of the base 130 for mounting the motor body 310. Shock-absorbing feet 340 are snapped into the quick-connect holes 132. The shock-absorbing feet 340 are made of a shock-absorbing material with good elasticity and energy absorption properties, preferably rubber, to reduce vibration transmission during motor operation, thereby enhancing stability and reducing noise. Several sheet-like base support frames 133 are evenly formed at the bottom of the base 130 to improve the overall support stability of the geared motor.
[0025] The connecting end cover 200 consists of a square end cover flange 210 and a cross flange 220. The connecting end cover 200 has an eccentric bushing hole 230 at an off-center location. During installation, the coupling 330 is located within the bushing space formed by the base bushing 111 and the eccentric bushing hole 230. The eccentric bushing hole 230 has a plum blossom-shaped opening 231 at one end facing the motor mounting base 100. A bushing baffle 232 is formed on the inner side wall of the eccentric bushing hole 230. The plum blossom-shaped arc edge fits against one side of the reducer bushing of the gear reducer 320, and the bushing baffle 232 limits and fixes the other side of the reducer bushing, enabling the gear reducer 320 to achieve eccentric reduction operation.
[0026] The end cover flange 210 has first screw holes 211 at each of its four corners, pointing from the connecting end cover 200 to the motor mounting base 100. Mounting screws 212 are installed in the first screw holes 211 to secure the connecting end cover 200 to the motor mounting base 100. The cross flange 220 has second screw holes 221 at each end of its cross face, pointing from the connecting end cover 200 to the gear reducer 320. Reducer mounting screws 222 are installed in the second screw holes 221 to secure the connecting end cover 200 to the gear reducer 320. The connecting end cover 200, through the integrated end cover flange 210 and cross flange 220, connects the gear reducer 320 and the motor mounting base 100. This avoids end face wear caused by direct connection between the motor body 310 and the gear reducer 320, extending the service life of the geared motor. Furthermore, different specifications of motor bodies 310 and gear reducers 320 can be selected for connection and matching according to the actual needs of the geared motor, making the geared motor more practical.
