[0003] Patent publication number CN109274209B relates to the field of motor technology. This patent provides a motor with a self-regulating speed function. A synchronous shaft extends axially outward from the end of the motor's output shaft. A first synchronous gear is disposed on the outer periphery of the synchronous shaft. A second synchronous gear is concentrically disposed on the axially outer end of the synchronous shaft. An interlocking disc is concentrically disposed on the axially outer end of the second synchronous gear. The interlocking disc has a plurality of first protrusions protruding from its outer periphery. The diameters of the interlocking disc, the second synchronous gear, and the first synchronous gear decrease in sequence. A coupling connects the load input shaft to the output shaft. A telescopic mechanism is disposed between the load input shaft and the output shaft to drive the coupling's axial movement. The coupling rotates synchronously with the load input shaft and is in shifted linkage with the interlocking disc, the second synchronous gear, and the first synchronous gear. This patent improves the motor structure and addresses the technical issue of a single motor control method.

[0004] In the above patent, the load input shaft and the output shaft are connected by a coupling, and a telescopic mechanism is set between the load input shaft and the output shaft to drive the coupling to move axially. The coupling rotates synchronously with the load input shaft, and the coupling is switched with the linkage disk, the second synchronous wheel and the first synchronous wheel. However, it is difficult to fix the gear transmission box after it is installed, which may easily cause the gear transmission box to be disconnected and fall due to vibration or other reasons when the motor is running, causing damage to the gear transmission box.

[0018] (3) This invention, after the oil outlet is opened, the lubricating oil flows into the gear box through the oil outlet and contacts the gear shaft 1 and the gear shaft 2, thereby reducing the friction of the metal surfaces in direct contact, reducing wear, and extending the service life of the gears.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-9One embodiment of the present invention is a motor with a self-regulating speed function, comprising a base 1, a motor body 2 fixedly mounted on the top of the base 1, a rotating shaft 3 fixedly mounted on the output end of the motor body 2, a gear box 4 fixedly mounted on the left side of the motor body 2, a gear shaft 1 5 rotatably mounted inside the gear box 4, a gear shaft 2 6 rotatably mounted inside the gear box 4, and a fixing device provided inside the gear box 4;

[0031] Among them, the fixing device includes a push rod 7, an elastic telescopic rod 8, an inclined block 9, a rubber ring 10, a fixed block 11, two inclined rods 12, a slider 13 and a push block 14. The push rod 7 is fixedly installed on the left side of the motor body 2, the elastic telescopic rod 8 is fixedly installed on the inner wall of the gear box 4, the inclined block 9 is fixedly installed on the bottom of the movable end of the elastic telescopic rod 8, the rubber ring 10 is fixedly installed on the movable end of the elastic telescopic rod 8, the fixed block 11 is fixedly installed on the left side of the motor body 2, the inclined rod 12 is slidably installed inside the gear box 4, the slider 13 is slidably installed inside the gear box 4, and the push block 14 is fixedly installed at the bottom of the slider 13. It moves through the rubber ring 10 to contact and fix the gear shaft 5, ensuring that the docking position between the gear shaft 5 and the rotating shaft 3 remains consistent, avoiding inaccurate docking during the next installation due to misalignment or loosening, reducing the time for adjustment and re-docking during the next docking, and improving work efficiency.

[0032] The sides of the push rod 7 and the inclined plane block 9 that are close to each other are set as inclined planes, the sides of the inclined plane rod 12 and the fixed block 11 that are close to each other are set as inclined planes, and the sides of the inclined plane rod 12 and the push block 14 that are close to each other are set as inclined planes. A card slot is provided inside the fixed block 11, and a spring 1 is provided between the two inclined plane rods 12. By setting the inclined plane, it is ensured that the inclined plane block 9 can be pushed smoothly by the push rod 7, and by setting the inclined plane, it is ensured that the inclined plane rod 12 can be pushed smoothly. By setting the inclined plane, it is ensured that the push block 14 can push the inclined plane rod 12 smoothly when moving, and by providing the card slot, it is ensured that the inclined plane rod 12 can be stuck into the fixed block 11.

[0033] When this embodiment is working: the staff moves the gear box 4, and faces the installation side of the gear box 4 to the output end of the motor body 2, and then aligns the rotating shaft 3 to install the gear box 4 at the output end of the motor body 2.

On the contrary, when the gear box 4 is removed from the motor body 2 after the work is completed, the push rod 7 no longer pushes the inclined plane block 9. Then the movable end of the elastic telescopic rod 8 drives the rubber ring 10 to start moving and resetting. The rubber ring 10 moves to contact with the gear shaft 5 and fix the gear shaft 5, ensuring that the docking position between the gear shaft 5 and the rotating shaft 3 remains consistent, avoiding inaccurate docking during the next installation due to misalignment or loosening, reducing the time for adjustment and re-docking during the next docking, and improving work efficiency.

When the fixed rod 155 moves, the slide plate 159 is pushed to start moving, and the slide plate 159 moves to open the collection tank at the bottom of the gear box 4. After the collection tank is opened, impurities fall into the collection box 158, which can effectively prevent impurities from entering the key components of the equipment, avoid equipment wear, blockage or failure due to the presence of impurities, and thus extend the service life of the equipment.

[0041] As the movable end of the elastic telescopic rod 3 154 moves and contracts, it drives the long rod 166 to start moving, and the movement of the long rod 166 drives the movable door 165 to start moving.

The pump 162 is turned on, and the oil suction pump 162 is started to suck the lubricating oil filtered by the filter plate 1510 from the bottom of the gear box 4 back into the oil tank 161 through the oil suction pipe 163, thereby reducing the waste of lubricating oil and extending the service life of the oil product, and reducing the frequency of changing the lubricating oil, thereby reducing the cost of oil purchase and replacement. When the lubricating oil in the oil tank 161 is insufficient and the gear box 4 is no longer working, the staff manually pulls the movable door 2 168 to open the refueling port. After the refueling port is opened, the lubricating oil is added to the inside of the oil tank 161. After the adding is completed, the movable door 2 168 is released, and then the movable door 2 168 begins to reset under the action of the movable end of the elastic telescopic rod 4 169.
