[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Please refer to Figures 1 to 4 The utility model provides a gear reduction motor, including a motor 1 and a reduction box 2, wherein the right end of the reduction box 2 is provided with an input shaft 21, and the outer periphery of the input shaft 21 is provided with a connecting platform 22; the connecting platform 22 is fixedly arranged at the right end of the reduction box 2, and the connecting platform 22 is flush with the right end surface of the reduction box 2; the left end of the motor 1 is provided with an output shaft, and the outer periphery of the output shaft is provided with a connecting plate 12, and the connecting plate 12 is fixedly arranged on the motor 1; the input shaft 21 is drivingly connected to the output shaft, and the connecting platform 22 is detachably connected to the connecting plate 12.

[0027] The gear reduction motor adopts a connection method of connecting platform 22 and connecting platform 22. The connecting platform 22 is flush with the right end face of the reduction box 2, saving the length of a flange. While ensuring the stable connection between the motor 1 and the reduction box 2, the overall length of the gear reduction motor is reduced, which is beneficial to reducing the overall space occupied by the gear reduction motor, so that the gear reduction motor can be adapted to more equipment with smaller space.

[0028] Specifically, the connecting plate 12 is provided with a connecting bolt 121 and a connecting through hole, and the connecting platform 22 is provided with a connecting screw hole 221 adapted to the position of the connecting through hole. The connecting bolt 121 passes through the connecting through hole and is threadedly connected to the connecting screw hole 221, so that the connecting plate 12 is tightly against the connecting platform 22.

[0029] With the above structure, the connecting plate 12 is pressed against the connecting platform 22 by the connection bolts 121, the connection through holes and the connection screw holes 221, so that the connecting platform 22 and the connecting plate 12 are detachably connected. The above structure is simple and easy to install and disassemble.

[0030] Specifically, the output shaft includes a transmission shaft 111 and a connecting sleeve 112; one end of the transmission shaft 111 is connected to the rotating assembly of the motor 1, and one end of the connecting sleeve 112 is sleeved on the other end of the transmission shaft 111; the other end of the connecting sleeve 112 is provided with a slot 1121, and the side wall of the slot 1121 is provided with a limiting groove 1122;

[0031] The side wall of the input shaft 21 is provided with a fixing protrusion 211 which is adapted to the position and shape of the limiting groove 1122 , the other end of the connecting sleeve 112 extends out from the motor 1 , the input shaft 21 is inserted into the slot 1121 , and the fixing protrusion 211 is inserted into the limiting groove 1122 .

[0032] The fixed protrusion 211 is stuck in the limiting groove 1122. When the output shaft rotates, the fixed protrusion 211 cooperates with the limiting groove 1122 to drive the input shaft 21 to rotate. The above structure can prevent the output shaft and the input shaft 21 from deflecting and loosening during long-term use, and avoid the output shaft and the input shaft 21 from working unstably.

[0033] Specifically, the reduction box 2 is a two-stage reduction box. In a specific embodiment of the present utility model, the reduction box 2 is a two-stage reduction box, which is used to reduce the rotation speed of the input shaft 21 and increase the torque of the output shaft to provide a larger output torque.

[0034] Specifically, a control box 13 is provided on the top of the motor 1. An electronic centrifugal switch is installed in the control box 13. The control box 13 is electrically connected to an external power supply through a line.

[0035] The control box 13 is installed on the top of the motor 1, which makes reasonable use of space, is easy to install, and is convenient for line layout. In addition, the electronic centrifugal switch can be started and stopped frequently, has strong anti-vibration and anti-interference properties, and has a long service life.

[0036] Optionally, a heat dissipation chamber 14 is provided at the right end of the motor 1 , and a plurality of heat dissipation holes 141 are provided at the right end of the heat dissipation chamber 14 , and the heat dissipation holes 141 are distributed circumferentially with the axis of the motor 1 as the central axis.

[0037] The heat dissipation chamber 14 serves to dissipate heat. The heat generated during the operation of the motor 1 is discharged from the heat dissipation chamber 14 through the heat dissipation holes 141, which can maintain the normal operating temperature of the motor 1, help prevent the motor 1 from overheating and being damaged, extend the service life of the motor 1, and ensure the stability and reliability of the motor 1.

[0038] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way.
