Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet speed regulators, and particularly to a horizontal water-cooled double-cylinder permanent magnet speed regulator. Background Art

[0002] For high-power drive load-bearing mechanisms, which connect the drive device and the load device through mechanical devices and use traditional mechanical cooperation for transmission, some non-eliminable problems will occur, such as mechanical fatigue, frictional loss, vibration noise, etc. Precise installation accuracy must be ensured to guarantee the stability of mechanical movement. However, after long-term use, equipment damage may be caused due to mechanical vibration or wear. The speed-changing device of the drive load-bearing mechanism is a device that changes the transmission ratio or speed of the output shaft and the input shaft. Using traditional speed regulation methods, the maintenance is cumbersome and the cost is high, which affects the use and sustainability of the equipment. High-power drive load-bearing mechanisms transmit large torques and have high requirements for transmission devices. Traditional air-cooled permanent magnet speed regulators dissipate heat through air for equipment operation. The heat dissipation efficiency is relatively low, and too high temperature will cause equipment damage, unable to meet the requirements of high-power drive load-bearing mechanisms. Summary of the Invention

[0003] The purpose of the present invention is to provide a horizontal water-cooled double-cylinder permanent magnet speed regulator in which the permanent magnet rotor assembly and the conductor rotor assembly are cooled by cooling water, with good heat dissipation effect and suitable for large-power equipment.

[0004] The present invention is achieved by the following measures: A horizontal water-cooled double-cylinder permanent magnet speed regulator, characterized in that it includes a permanent magnet rotor assembly arranged on the load shaft, a conductor rotor assembly arranged on the motor input shaft, and a housing arranged outside the permanent magnet rotor assembly and the conductor rotor assembly. The load shaft is rotationally connected to one end of the housing, the motor input shaft is rotationally connected to the other end of the housing, a water inlet is arranged on any end face of the housing, and a water outlet is arranged at the lower part of the side of the housing. The housing is a hollow sealed body, which can be integrally provided or assembled through detachable connectors, generally a hollow cylinder, which is convenient for installation. In addition, an observation port and a support seat for easy fixation are also arranged on the housing.

[0005] The permanent magnet rotor assembly includes a permanent magnet disk, and a permanent magnet ring is arranged on any side of the permanent magnet disk. The permanent magnet disk is arranged on the load shaft;

[0006] The conductor rotor assembly includes a conductor disk, and an outer conductor ring and an inner conductor ring are concentrically arranged on any side of the conductor disk. The conductor disk is arranged on the motor input shaft;

[0007] The permanent magnet ring is arranged between the outer conductor ring and the inner conductor ring with intervals therebetween. A plurality of water passing holes are provided on the conductor disk. An annular water blocking plate is provided on the inner side of the inner conductor ring. The annular water blocking plate is arranged on the conductor disk and outside the water passing holes. A plurality of through holes are provided on the annular water blocking plate.

[0008] An annular water tank is provided on one side of the conductor disk close to the water inlet. A water injection pipe is provided on the water inlet. One end of the water injection pipe is connected to a water source, and the other end is arranged in the annular water tank. This can facilitate the injection and retention of water.

[0009] The motor input shaft is arranged at one end of the housing through a bearing I. The load shaft is arranged at the other end of the housing through a bearing II. A water receiving tank is provided on the housing and below the water outlet. A drain port is provided on the water receiving tank.

[0010] A flange is provided at one end of the motor input shaft. The conductor disk is arranged on the flange. An annular waterproof plate I is provided between the bearing I and the flange. The annular waterproof plate I is arranged on the end cover of the bearing I;

[0011] The permanent magnet disk is arranged on the load shaft through a key connection. An annular waterproof plate II is provided between the permanent magnet disk and the conductor disk. The annular waterproof plate II is arranged on the permanent magnet disk.

[0012] An annular waterproof plate III is provided above the annular waterproof plate I. The annular waterproof plate III is arranged on the flange. The annular waterproof plate I and the annular waterproof plate III partially overlap;

[0013] An annular waterproof plate IV is provided above the annular waterproof plate II. The annular waterproof plate IV is arranged on the flange. The annular waterproof plate II and the annular waterproof plate IV partially overlap. Since the permanent magnet speed regulator has an adjusting mechanism and the permanent magnet disk needs to move axially, the waterproof plate cannot be in contact with the components on both sides. However, if it is not in contact, it will affect the waterproof effect. Therefore, two water blocking plates with overlapping parts are provided, so that the waterproof purpose can still be achieved even in the adjusted state.

[0014] The annular waterproof plate I, the annular waterproof plate II, the annular waterproof plate III, and the annular waterproof plate IV are all frustum-shaped and the non-connected ends are the large ends, and the large ends incline outwards, so that the waterproof effect is better.

The two rocker arms are located on both sides of the load shaft, and a power mechanism is provided at any one end of the rotating shaft. The power mechanism can be a manually operated rotating wheel or a motor with a speed reducer. When the rotating shaft rotates, the rocker arms and the connecting rod drive the permanent magnetic disk to move linearly along the axis. The permanent magnetic disk moves axially, changing the coupling area between the permanent magnetic ring and the outer conductor ring and the inner conductor ring, thereby changing the torque transmitted between the conductor rotor assembly and the permanent magnetic rotor assembly, achieving the speed regulation effect.

[0017] The third bearing and the sliding sleeve are arranged in the housing. A water baffle is sleeved on the sliding sleeve between the third bearing and the permanent magnetic disk, and the water baffle is fixedly arranged on the inner wall of the housing. This can waterproof the speed regulation mechanism.

A fourth bearing is arranged in the blind hole, and the fourth bearing is fixed on the motor input shaft through an outer end cover. The load shaft passes through the fourth bearing and is arranged in the blind hole. In this way, when adjusting, a part of the load shaft can extend into the blind hole, reducing the volume of the device as a whole.

[0019] A limiting top plate is arranged in the blind hole to limit the adjustment range of the load shaft.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The permanent magnetic rotor assembly and the conductor rotor assembly are cooled by cooling water, with good heat dissipation effect, suitable for high-power equipment; a waterproof structure is provided at the corresponding bearing connection, and a plurality of water passing holes are arranged on the conductor disk to increase the cooling effect; in addition, there is also an adjustment mechanism composed of the rocker arm and the connection.

The load shaft 3 is rotationally connected and arranged at one end of the housing 1, the motor input shaft 2 is rotationally connected and arranged at the other end of the housing 1. A water inlet is arranged on any end face of the housing 1, and a water outlet 601 is arranged at the lower part of the side face of the housing 1. The housing 1 is a hollow sealed body, which can be integrally arranged or assembled through detachable connecting pieces, generally a hollow cylinder, which is convenient for installation.

A plurality of through holes are arranged on the annular water isolation plate 206.

[0033] On one side of the conductor disk 203 close to the water inlet, an annular water groove 209 is provided. A water injection pipe 4 is provided on the water inlet. One end of the water injection pipe 4 is connected to a water source, and the other end is arranged in the annular water groove 209. This can facilitate the injection and retention of water.

The power mechanism can be a manually operated rotating wheel or an electric motor with a speed reducer. When the rotating shaft 501 rotates, the rocker arms 503 and the connecting rod 504 drive the permanent magnetic disk 302 to move linearly along the axis. The permanent magnetic disk 302 moves axially to change the coupling area between the permanent magnetic ring 303 and the outer conductor ring 204 and the inner conductor ring 205, thereby changing the torque transmitted between the conductor rotor assembly and the permanent magnetic rotor assembly and achieving the speed regulation function.

[0042] The third bearing 506 and the sliding sleeve 505 are arranged in the housing 1.
