Description

Technical Field

[0001] The invention relates to the technical field of motors, in particular to an energy-saving three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor is a kind of induction motor. Its main function is to generate driving torque. As the power source of electrical appliances or machinery, it is a type of motor that is powered by 380V three-phase AC current. Because the rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. Compared with the single-phase asynchronous motor, the three-phase asynchronous motor has good operating performance and can save various materials, so the three-phase asynchronous motor is widely used in the market.

[0003] Due to its wide range of applications, and it is mostly used in scenarios such as reducers, the structure of the small gear driving the large gear through the rotation of the motor output shaft changes its torque to achieve the effect of deceleration and labor saving. Among them, the planetary gear structure is more commonly used, but due to the complexity of the planetary gear structure, its vibration and noise problems are also more prominent, and gear tooth fatigue pitting is very likely to occur. In addition, during the operation of the gear, a large amount of metal debris will be generated on the tooth surface. These debris accumulate in the tooth surface gap, which will cause local wear to increase. Due to the meshing relationship between the teeth, the debris is often squeezed and fitted to the tooth root, and needs to be disassembled and cleaned regularly, affecting work efficiency. In addition, as the gear wear increases, the meshing between the gears will not be loose enough, resulting in axial vibration. As the looseness increases, the vibration amplitude will also increase, thereby causing noise pollution. Summary of the invention

The three planetary shafts 84 are rotatably arranged between two tripods 17. The three planetary gears 82 are respectively fixedly arranged on the three planetary shafts 84. The sun gear 81 is fixedly arranged on the connecting shaft 18. The gear ring 83 is sleeved on the three planetary gears 82, and the gears are rotatably connected with the protective shell 10. The sun gear 81 is driven to rotate by the rotation of the connecting shaft 18, the sun gear 81 is driven to rotate by the rotation of the planetary gears 82, and the planetary gears 82 are driven to rotate by the gear ring 83; the pinion drives the large gear, and the lever principle is used to increase the torque, so that the output shaft of the motor body 1 can be rotated more labor-saving.

In addition, due to the increase in oil outlet pressure, the resistance to axial movement can also be increased, thereby achieving the effect of assisting in reducing axial stability, and flushing the stubborn debris at the root of the tooth, with a good cleaning effect, without the need for manual disassembly and cleaning, which greatly improves work efficiency and reduces the labor intensity of the staff.

When the shaft sleeve 3 moves and drives the mounting plate 48 to move toward the gear ring 83, the movement of the mounting plate 48 drives the first rotating shaft 43 and the first rotating plate 45 to move synchronously. At this time, the second rotating plate 47 abuts against the obstruction plate 410, and the second rotating plate 47 is limited by the limit block 46, so that the second rotating plate 47 cannot rotate, so that the first rotating plate 45 rotates around the first rotating shaft 43, and resets after the first rotating plate 45 passes over the obstruction plate 410.

The first ball head 65 and the second ball head 610 slide in the first thread groove 68 and the second thread groove 612, thereby synchronously driving the first U-shaped slide bar 64 and the second U-shaped slide bar 67 to move upward and downward respectively, so that the distance between the two increases, until the first ball head 65 and the second ball head 610 move to the inside of the first horizontal annular groove 62 and the second horizontal annular groove 611 to perform horizontal annular motion, the rotation of the hollow shaft drives the transmission shaft 11 to rotate, and the rotation of the transmission shaft 11 drives the transmission member 12 to rotate, and with the increase of the use time, the wear between the synchronized gears increases, thereby reducing the meshing tightness between the planetary gear assembly 8, and the meshing tightness The degree of reduction increases the axial vibration amplitude during transmission, and the movement of the shaft sleeve 3 drives the connecting shaft 18 to move synchronously, and the movement of the connecting shaft 18 drives the U-shaped connecting rod 54 and the L-shaped rod 53 to move synchronously, and the movement of the U-shaped connecting rod 54 drives the extrusion plate 55 to move, and the lubricating oil inside the oil storage box 56 is squeezed out and flows into the inside of the oil injection box 51 through the oil outlet pipe 57. At the same time, the L-shaped rod 53 moves to resist the two wedge blocks 58 to move toward both sides, and the movement of the wedge block 58 drives the baffle plate 59 to move synchronously, and the baffle plate 59 moves toward both sides, so that the oil outlet of the oil injection box 51 becomes narrower. Due to the narrowing of the oil outlet of the oil injection box 51, the internal oil pressure increases, and the oil in the oil storage box 56 is synchronously moved. When the shaft sleeve 3 moves and drives the mounting plate 48 to move toward the gear ring 83, the mounting plate 48 moves and drives the first rotating shaft 43 and the first rotating plate 45 to move synchronously. At this time, the second rotating plate 47 abuts against the obstruction plate 410, and the second rotating plate 47 is limited by the limit block 46, so that the second rotating plate 47 cannot rotate, so that the first rotating plate 45 rotates around the first rotating shaft 43, and resets after the first rotating plate 45 passes over the obstruction plate 410. When the shaft sleeve 3 moves toward the motor body 1, the second rotating plate 47 is rotated by the obstruction plate 410, and the first rotating plate 45 remains in a vertical state to collect the lubricating oil containing debris.
