Description

Technical Field

[0001] This utility model relates to a bearing replacement device. Background Technology

[0002] A pitch motor is a device used to adjust the angle of wind turbine blades. By changing the angle of the blades, it controls the speed and output power of the wind turbine, thereby achieving efficient and stable operation of wind power generation.

[0003] The pitch motor receives signals from the control system and drives the blades to rotate around its axis, thereby changing the angle between the blades and the wind direction. When the wind speed is low, the pitch motor adjusts the blade angle to be larger, allowing the blades to capture more wind energy and increasing the rotor speed and output power. When the wind speed is high, the pitch motor adjusts the blade angle to be smaller, reducing the absorption of wind energy by the blades, limiting the rotor speed and output power, and preventing the wind turbine from being damaged due to overload.

[0004] The bearings installed at the output end of existing motors have deformed inner rings due to long-term use, making them difficult to remove when replacing the bearings. Existing methods such as hammering and striking are used to remove the bearings, which can easily damage internal components of the motor. Therefore, a bearing replacement device is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A bearing replacement device includes a base 1, a placement groove 2 is formed on the upper end face of the base 1, a motor fixing assembly is provided on the upper end face of the base 1, a bearing picking assembly is provided on the base 1, and an adjustment assembly is provided at the bottom of the placement groove 2.

[0024] Specifically, the motor fixing assembly includes two fixing plates 3 located at the opening of the placement slot 2; each fixing plate 3 has a slider 4 connected to both ends; the upper surface of the base 1 has multiple sliding grooves 5, and the sliders 4 are slidably connected in the corresponding sliding grooves 5; the fixing plates 3 are connected to a sliding drive assembly. The sliding drive assembly includes a double-ended threaded screw 6, and each slider 4 at the same end of the two fixing plates 3 is connected to a screw nut 7, which are respectively connected to both ends of the double-ended threaded screw 6; a through-shaft motor 8 is connected to the middle of the double-ended threaded screw 6. Each end of the double-ended threaded screw 6 is rotatably connected to a rotating seat 9. The threads at both ends of the double-ended threaded screw 6 are arranged in opposite directions; clockwise rotation will cause the fixing plates 3 connected at both ends to separate, and counterclockwise rotation will cause the two fixing plates to move closer together.

[0025] Specifically, the through-shaft motor 8 rotates to drive the connecting screw nut 7 to move closer. The two screw nuts 7 move closer to drive the connecting fixing plate 3 to move closer. The motor whose bearing needs to be replaced is placed in the placement slot 2. The output shaft of the motor and the connected bearing are located above the fixing plate 3. The two fixing plates 3 press the end face of the motor against the lower end face of the fixing plate 3, which can prevent the motor body from shaking when removing the bearing.

[0026] Specifically, the bearing assembly includes a picking cylinder 10, the output end of which is connected to a horizontal plate 11. Each end of the horizontal plate 11 is rotatably connected to a picking rod 12, and the lower end of each picking rod 12 is connected to a picking clamping plate 13. A stop block 20 is connected to the upper end of each picking rod 12. A support column 14 is connected to the upper surface of the base 1, and a top plate 15 is connected to the upper end of the support column 14. Both the horizontal plate 11 and the top plate 15 have oblong grooves 16 for sliding the picking rods 12. The oblong grooves 16 allow the picking rods 12 to move, and the distance between the two picking rods 12 can be adjusted to accommodate different bearings.

[0027] Specifically, after the motor is fixed in the placement slot 2, the material picking rod 12 is rotated so that the material picking plate 13 is located at the lower end face of the bearing. The material picking cylinder 10 is started. The material picking cylinder 10 drives the material picking rod 12 to rise through the horizontal plate 11. The rise of the material picking rod 12 drives the material picking plate 13 to move upward, and removes the bearing on the motor output shaft.

[0028] Specifically, the adjustment assembly includes an adjustment plate 17, which is slidably connected within the placement groove 2. A second nut 18 is embedded in the bottom of the placement groove 2, and an adjustment screw 19 is connected within the second nut 18. The upper end of the adjustment screw 19 is rotatably connected to the lower end face of the adjustment plate 17. For motors of different sizes, the adjustment screw 19 can be rotated to raise or lower the adjustment plate 17, allowing the motor to be completely placed within the placement groove 2.

[0029] Specifically, in use, the through-shaft motor 8 is started. The through-shaft motor 8 rotates in reverse, driving the double-ended threaded screw 6 to rotate in reverse, causing the two fixing plates 3 to separate and slide to both sides of the upper port of the placement slot 2. The motor body whose bearing needs to be replaced is placed in the placement slot 2, so that the motor output shaft and the connected bearing to be removed are located on the upper end face of the base 1. The through-shaft motor 8 is started, and the through-shaft motor 8 rotates in the forward direction, driving the double-ended threaded screw 6 to rotate in the forward direction, causing the two fixing plates 3 to come closer. The opposing surfaces of the two fixing plates 3 are both semi-circular, so that when the two fixing plates 3 are closed, they can avoid the output shaft of the motor. When the two fixing plates 3 are closed, they press down on the motor. The motor body will not move when the motor output shaft bearing is pulled out. Then, rotate the picking rod 12 to rotate the picking plate 13 to the bottom of the bearing to be picked. Start the picking cylinder 10. The picking cylinder 10 extends and drives the picking rod 12 to rise. The rising of the picking rod 12 causes the picking plate 13 to rise and drive the bearing to be picked to move upward from the motor output shaft, so that the bearing to be picked is removed from the motor output shaft. Then, the through-shaft motor 8 reverses and drives the double-headed threaded screw 6 to reverse, so that the two fixing plates 3 separate and the motor is removed from the placement slot 2. A new bearing is installed on the motor output shaft to complete the bearing replacement.

[0030] This bearing replacement device, by setting up a motor fixing assembly and a bearing removal assembly, smoothly removes the used bearings by machine, avoiding damage to the internal components of the motor. Moreover, the device is easy to operate when removing bearings, improving efficiency.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
