Description

Technical Field

[0001] The invention relates to the technical field of electric motors, in particular to an electric motor with a self-lubricating structure. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrodynamic rotating torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The electric motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the motor is the effect of the magnetic field on the force on the current, causing the motor to rotate.

[0003] For example, an electric motor with a self-lubricating structure with announcement number CN216599225U includes a motor body, a bearing sleeve fixedly installed on the left side of the motor body, a connecting bearing fixedly installed on the inner wall of the bearing sleeve, a rotating shaft is provided inside the motor body, the left end of the rotating shaft passes through the connecting bearing and extends to the outside of the bearing sleeve, a sealing cylinder is fixedly connected to the outer surface of the motor body, and a piston on the inner wall of the sealing cylinder is connected to a piston plate. A return spring is provided, and the rebound force provided by the return spring is utilized to push the movable plate to slide inside the sealing cylinder, and at the same time, pressure is applied to the lubricating oil, so that the lubricating oil enters the bearing sleeve through the oil pipeline, and the heat generated by the movement of the connecting bearing and the rotating shaft causes the lubricating oil to melt and lubricate the connecting bearing and the rotating shaft, thereby facilitating the addition of lubricating oil and reducing the wear of the connecting bearing and the rotating shaft.

[0004] During the use of traditional electric motors, not only the bearings need lubrication, but also the armature bearings, the connecting pins of the brake system, the shafts, the brake screws, the hinges of the sand removal device, the bearing box slides, the balance beams, the gear spring sheets and the hinges of the balance beam, as well as the various rotating bearings and cams of the controller. The traditional lubrication structure only performs point oiling on the bearings, and other areas are easily overlooked.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4-Figure 9 A motor with a self-lubricating structure includes a motor body 1. A rotating shaft 2 is arranged in the middle of the motor body 1. After the motor body 1 is started, the rotating shaft 2 can rotate. A storage mechanism 3 is arranged inside the motor body 1. The storage mechanism 3 includes an annular cylinder 31 arranged inside the motor body 1. The annular cylinder 31 is arranged as an annular hollow structure, and its interior is used to store lubricating oil for lubricating the motor body 1. An annular groove 35 is opened on the inner wall of the annular cylinder 31.

[0025] A flow guide mechanism 4 is provided on one side of the storage mechanism 3. The flow guide mechanism 4 includes a limit ring 41 slidably mounted inside the annular cylinder 31. The width of the limit ring 41 is greater than the width of the annular groove 35. The limit ring 41 rotates in the annular cylinder 31 to cover the annular groove 35. Therefore, the interior of the annular cylinder 31 is a closed chamber, and the lubricating oil inside the annular cylinder 31 will not be lost. One end of the limit ring 41 is connected to a guide cylinder 42, and one end of the guide cylinder 42 is connected to an extrusion cylinder 44. The guide cylinder 42 is a cylindrical structure with openings at both ends. Its upper end is connected with the inner cavity of the annular cylinder 31, and its lower end is connected with the extrusion cylinder 44. A rubber ball 45 is installed on one side of the extrusion cylinder 44. The rubber ball 45 is a spherical structure made of rubber material and can be reset after any deformation. A first oil outlet hole 47 is opened on the rubber ball 45. The lubricating oil inside the annular cylinder 31 can flow along the guide cylinder 42, the extrusion cylinder 44, and the rubber ball 45, and finally flow out from the first oil outlet hole 47. The rubber ball 45 is arranged on the outer periphery of the rotating shaft 2 to lubricate the outer periphery of the rotating shaft 2.

[0026] A connecting mechanism 5 is also provided on one side of the storage mechanism 3 . The connecting mechanism 5 includes a connecting rod 51 arranged inside the extrusion cylinder 44 . A connecting cylinder 55 is fixedly installed at the lower end of the connecting rod 51 . The lower end of the connecting cylinder 55 is fixedly installed at the upper end of the extrusion cylinder 44 .

[0027] Before starting the motor body 1, the user first injects lubricating oil into the annular cylinder 31. The space inside the annular cylinder 31 is relatively large and is used to store lubricating oil. When the rotating shaft 2 needs to be lubricated, the lubricating oil flows out from the guide cylinder 42, the connecting cylinder 55, the extrusion cylinder 44, the rubber ball 45, and the first oil outlet 47 in sequence, thereby flowing to the outer periphery of the rotating shaft 2 to lubricate the rotating shaft 2.

[0028] A wavy slide rail 36 is provided on the inner wall of the annular cylinder 31. Two wavy slide rails 36 are provided. The two wavy slide rails 36 are respectively installed on the two inner walls of the annular cylinder 31. The wavy slide rail 36 is an annular wavy structure connected end to end. Sliding rods 52 are fixedly installed on both sides of the connecting rod 51. A sliding ball 53 is fixedly installed on one end of the sliding rod 52. The sliding ball 53 is slidably installed in the wavy slide rail 36.

[0029] The guide mechanism 4 and the connecting mechanism 5 are driven to rotate, and the sliding ball 53 is slidably installed in the wavy slide rail 36, that is, the connecting rod 51 and the connecting cylinder 55 move up and down in the guide cylinder 42, and also drive the extrusion cylinder 44 and the rubber ball 45 at the lower end of the connecting cylinder 55 to move up and down. When the sliding ball 53 slides to the lowermost end of the wavy slide rail 36, the rubber ball 45 presses the rotating shaft 2 downward, the rubber ball 45 is deformed, and the speed and range of oil discharge from the first oil outlet 47 are increased.

[0030] When the sliding ball 53 slides to the uppermost end of the wavy slide rail 36, the rubber ball 45 resets upward, and the lubricating oil fills the connecting cylinder 55, the extrusion cylinder 44 and the rubber ball 45 again. The rubber ball 45 is squeezed repeatedly, so as to automatically drive the lubricating oil to a farther place. Not only the bearings need lubrication, but also the armature bearings, the connecting pins, shafts, brake screws of the braking system, the hinges of the sand removal device, the bearing box slide, the balance beam, the gear spring sheet and the hinges of the balance beam, as well as the rotating bearings and cams of the controller can be lubricated by the splashed lubricating oil, which reduces the lubrication and plays a role of non-contact lubrication, and greatly increases the lubrication efficiency.

[0031] Example 2: Please refer to Figure 1-Figure 9 The motor body 1 includes an outer shell 11 and a mounting shell 12 arranged at the front and rear sides of the outer shell 11 , and a driving member 13 is arranged inside the outer shell 11 .

[0032] The rotating shaft 2 includes a rotating shaft body 21 arranged in the middle of the driving member 13. A bearing 22 is commonly arranged between the rotating shaft body 21 and the mounting shell 12. The bearing 22 serves as one of the lubrication points of the motor body 1. The device is installed on one side of the bearing 22 so that the bearing 22 does not contact other structures. After repeated squeezing of the rubber ball 45, the lubricating oil can still be sprayed onto the bearing 22, further reducing the friction of the bearing 22. A slide groove 23 is provided on the outer periphery of the rotating shaft body 21. When the rubber ball 45 rotates into the slide groove 23, the lubricating oil can be stored in the slide groove 23. As the lubricating oil flows, the motor body 1 is lubricated again.

[0033] The storage mechanism 3 also includes a feed barrel 32 connected and installed on one side of the annular barrel 31. The feed barrel 32 is connected to the mounting shell 12. A limit block 33 is fixedly installed on the outer periphery of the feed barrel 32. A first elastic member 34 is commonly installed between the mounting shell 12 and the annular barrel 31. The first elastic member 34 is arranged on the outer periphery of the feed barrel 32. The first elastic member 34 is a component made of any elastic structure such as a spring or a bellows. The annular barrel 31 is clamped in the outer shell 11 through the feed barrel 32. The first elastic member 34 is in a compressed state, and its reaction force is against the annular barrel 31, which is convenient for buffering the annular barrel 31, reducing the damage of the annular barrel 31 or the leakage of lubricating oil due to the vibration of the motor body 1, and has a certain degree of protection.

[0034] An annular adsorbent 37 is fixedly installed inside the annular cylinder 31. The annular adsorbent 37 can be made of sponge. The lubricating oil is injected into the annular cylinder 31 through the feeding cylinder 32 and is adsorbed by the annular adsorbent 37 for long-term storage of the lubricating oil. A collecting cylinder 38 is fixedly installed on the inner wall of the annular cylinder 31. The two sides of the collecting cylinder 38 are respectively connected to the mounting shell 12 and the driving member 13. As the rotating shaft body 21 rotates, the lubricating oil in the slide groove 23 drips downwards one after another, and the collecting cylinder 38 at the lower end can collect the lubricating oil again, thereby reducing the waste of the lubricating oil.

[0035] Telescopic rods 43 are provided on both sides of the guide cylinder 42, and a recovery hole 46 is also provided on one side of the guide cylinder 42 close to the limit ring 41. The recovery hole 46 is arranged at the collecting cylinder 38. The lubricating oil collected in the collecting cylinder 38 can flow back to the annular cylinder 31 through the recovery hole 46, so as to facilitate the recycling of the lubricating oil.

[0036] Example 3: Please refer to Figure 2-Figure 9 A squeezing block 54 is fixedly installed on the upper end of the connecting rod 51, and the squeezing block 54 is connected to the annular adsorption member 37. The lubricating oil inside the annular cylinder 31 is absorbed by the annular adsorption member 37. During the up and down movement of the connecting rod 51, the squeezing block 54 exerts pressure on the annular adsorption member 37, so that the lubricating oil in the annular adsorption member 37 is squeezed out and flows downward through the guide cylinder 42. When the connecting rod 51 no longer moves up and down, the lubricating oil can be re-absorbed by the annular adsorption member 37, and the lubricating oil cannot flow out, which is convenient for long-term storage.

[0037] A first connecting block 56 is fixedly installed on both sides of the lower end of the connecting tube 55, and the first connecting block 56 is slidably installed in the telescopic rod 43. A pull rod 58 is fixedly installed on the lower end of the sliding rod 52, and a blocking block 59 is fixedly installed on the lower end of the pull rod 58. The lower end of the blocking block 59 is also fixedly connected to the second elastic member 48.

[0038] In the initial state, the sliding ball 53 is located at the lower end of the wavy slide rail 36, and the block 59 is blocked at the upper end of the guide cylinder 42. Therefore, the lubricating oil is doubly locked in the annular cylinder 31. When the sliding ball 53 slides upward, the connecting rod 51, the sliding rod 52, and the connecting cylinder 55 move upward in the guide cylinder 42, and the extrusion block 54 applies pressure on the annular adsorption member 37, thereby driving the block 59 at the lower end of the sliding rod 52 away from the guide cylinder 42, and the lubricating oil can fill the guide cylinder 42, the connecting cylinder 55, the extrusion cylinder 44 and the rubber ball 45. When the sliding ball 53 moves downward, the block 59 blocks the guide cylinder 42 again and moves to the lower end of the recovery hole 46. There is only one channel, the first oil outlet 47, inside the guide cylinder 42, the connecting cylinder 55, the extrusion cylinder 44 and the rubber ball 45. With the extrusion of the rubber ball 45, the lubricating oil injection range is further increased. The device can lubricate multiple lubrication points at one time, greatly improve the working efficiency, and have a good use effect.

[0039] Example 4: Please refer to Figure 2-Figure 10 A support rod 57 is rotatably mounted on one end of the first connecting block 56, and an extrusion mechanism 6 is arranged inside the motor body 1. The extrusion mechanism 6 includes two U-shaped ring bodies 61, and a second connecting block 62 is fixedly mounted on the upper end of one of the U-shaped ring bodies 61 and is rotatably connected to the support rod 57, and a protective cover 63 is installed between the two adjacent U-shaped ring bodies 61.

[0040] A material leveling mechanism 7 is arranged inside the extrusion mechanism 6, and the material leveling mechanism 7 includes a sliding frame 71 arranged inside the U-shaped ring body 61, and a fixed frame 72 is fixedly installed between adjacent sliding frames 71. An adsorption cover 73 is arranged inside the U-shaped ring body 61, and limit rods 76 are fixedly installed at both ends of the adsorption cover 73.

[0041] The adsorption cover 73 is a cylindrical structure. A plurality of adsorption covers 73 are connected together through a sliding frame 71 and a fixed frame 72 . The adsorption covers 73 are rotatably installed in the sliding frame 71 and the fixed frame 72 , and rotate in the U-shaped ring body 61 .

[0042] The adsorption cover 73 is also slidably installed in the sliding frame 71 through a limiting rod 76. The limiting rod 76 and the inner wall of the sliding frame 71 are connected by a third elastic member 77. The adsorption cover 73 located at the sliding groove 23 is embedded in the sliding groove 23 under the action of the third elastic member 77.

[0043] Through the cooperation among the U-shaped ring body 61, the second connecting block 62, the first connecting block 56 and the support rod 57, the U-shaped ring body 61 is connected with the connecting tube 55. During the rotation of the shaft body 21, the adsorption cover 73 is clamped in the slide groove 23, and the connecting tube 55 and the connecting rod 51 are linked to the rotation of the guide tube 42 and the limit ring 41, so that the connecting rod 51, the sliding rod 52 and the connecting tube 55 can move upward in the guide tube 42, and the two adsorption covers 73 can also slide left and right in the slide groove 23. After the device is started, the automatic injection of lubricating oil can be realized through the self-rotation of the shaft body 21, without the need for additional driving force, which is convenient for promotion and use.

[0044] An oil inlet hole 74 is formed on the outer periphery of the adsorption cover 73 , and a second oil outlet hole 75 is formed on a side of the adsorption cover 73 away from the rubber ball 45 .

[0045] The adsorption cover 73 can also rotate in the slide groove 23, and when it contacts the side wall of the slide groove 23, it can push the lubricating oil to both sides of the slide groove 23, so as to facilitate the guidance of the lubricating oil.
