Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to a motor which is convenient for applying lubricating oil based on the motor shaft. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy using the principle of electromagnetic induction. Its working principle is to use the interaction between the magnetic field and the current to generate torque, thereby driving the shaft to rotate. Motors are widely used in various fields, such as household appliances, industrial equipment, and transportation. Common types of motors include DC motors, AC motors, stepper motors, servo motors, etc. In order to reduce the wear of the motor output shaft, the motor output shaft usually needs to be lubricated. Manual application of lubricating oil may cause uneven application, and the operator needs to wear gloves to apply it, which increases the cumbersome process of application. For this reason, we propose a motor based on the motor shaft that is easy to apply lubricating oil. Utility Model Content

[0026] A lubricating oil application assembly, which is mounted on the protective sleeve 5 and is used to lubricate the outer wall of the motor output shaft 4;

[0027] The lubricating oil applying assembly includes a lubricating oil box 6, an oil inlet pipe 7, a limit strip 13 and an oil inlet hole 14. The outer wall of the motor output shaft 4 corresponds to the protective sleeve 5 and is slidably sleeved with the lubricating oil box 6. A vertical oil inlet pipe 7 is fixedly arranged on the top of the lubricating oil box 6. The inner wall of the lubricating oil box 6 is provided with an oil inlet hole 14 that penetrates into the lubricating oil box 6. The oil inlet pipe 7 is slidably clamped in the slide groove. Two sets of limit strips 13 are fixedly arranged on the inner wall of the lubricating oil box 6. The tooth groove 11 is meshed with the rack 12 and drives the ring sleeve 8 to rotate in the lubricating oil box 6 during the sliding process of the rack 12.

[0028] A plugging assembly, which is sleeved on the outer wall of the motor output shaft 4, is used to prevent the lubricating oil in the lubricating oil box 6 from being wasted;

[0029] The sealing component includes a ring sleeve 8, a limit ring 9, an oil inlet hole 10 and a tooth groove 11. The outer wall of the motor output shaft 4 is sleeved with a ring sleeve 8 corresponding to the inner wall of the lubricating oil box 6. One end of the ring sleeve 8 is provided with a plurality of groups of tooth grooves 11 arranged in a circular shape and at equal distances. The limit ring 9 is sleeved on the ring sleeve 8. The end of the ring sleeve 8 away from the tooth groove 11 is provided with four groups of oil inlet holes 10 arranged in a circular shape and at equal distances. The oil inlet pipe 7 is pushed toward one side of the motor 1, so that the oil inlet pipe 7 drives the lubricating oil box 6 to slide on the outer wall of the motor output shaft 4 and apply lubricating oil. The lubricating oil box 6 separates from the ring sleeve 8 during the sliding process. When the motor output shaft 4 needs to be lubricated, the lubricating oil is first injected into the oil inlet pipe 7, and the lubricating oil flows into the lubricating oil box 6 through the oil inlet pipe 7.

[0030] A rack 12 is slidably connected to the protective cover 5 near the top, and both ends of the rack 12 extend out of both sides of the protective cover 5. When the lubricating oil box 6 is filled with lubricating oil, the rack 12 is pulled to slide on the protective cover 5.

[0031] The end of the motor output shaft 4 extends out of the protective cover 5. A sliding groove is provided on the top of the protective cover 5. The oil inlet pipe 7 drives the lubricating oil box 6 to slide in the protective cover 5 to prevent the lubricating oil box 6 from rotating during the sliding process.

[0032] The oil inlet holes 14 are provided with four groups arranged equidistantly in a ring shape. When the four groups of oil inlet holes 10 on the ring sleeve 8 rotate and align one by one with the oil inlet holes 14 on the lubricating oil box 6, the lubricating oil in the lubricating oil box 6 flows into the outer wall of the motor output shaft 4 through the four groups of oil inlet holes 14 and the four groups of oil inlet holes 10.

[0033] The rack 12 is meshed with a plurality of groups of tooth grooves 11 , and the rack 12 drives the ring sleeve 8 to rotate on the outer wall of the motor output shaft 4 through the tooth grooves 11 .

[0034] Working principle: when the motor output shaft 4 needs to be lubricated, first inject lubricating oil into the oil inlet pipe 7, and the lubricating oil flows into the lubricating oil box 6 through the oil inlet pipe 7. When the lubricating oil in the lubricating oil box 6 is full, pull the rack 12 to make the rack 12 slide on the protective sleeve 5, and the tooth groove 11 drives the ring sleeve 8 to rotate in the lubricating oil box 6 during the sliding process of the rack 12 by meshing with the rack 12. When the four groups of oil inlet holes 10 on the ring sleeve 8 rotate and align with the oil inlet holes 14 on the lubricating oil box 6 one by one, the lubricating oil in the lubricating oil box 6 flows into the outer wall of the motor output shaft 4 through the four groups of oil inlet holes 14 and the four groups of oil inlet holes 10, and then push the oil inlet pipe 7 to one side of the motor 1, so that the oil inlet pipe 7 drives the lubricating oil box 6 to slide on the outer wall of the motor output shaft 4 and apply lubricating oil, and the lubricating oil box 6 separates from the ring sleeve 8 during the sliding process.
