Description

Technical Field

[0001] The invention relates to the technical field of wind power equipment, and in particular to a planetary gear regulating device for a box in wind power. Background Art

[0002] In wind power gearbox, the planetary gear adjusting device is used to adjust the position of the planetary gears to ensure the correct meshing between the gears. With the use of the gears, the gear surface may wear. The adjusting device can be used to fine-tune the position of the gears to compensate for this wear and maintain the best meshing state. During maintenance and overhaul, the adjusting device can be used to adjust the position of the gears to facilitate cleaning, lubrication or replacement of gears.

By rotating the screw rod with the handle, the limiting head moves. The component to be installed is placed between the two limiting heads. By moving the two limiting heads closer to each other, the component to be installed is limited. Through the cooperation of the screw rod and the limiting head, the component to be installed can be accurately positioned at the predetermined position, ensuring the accurate installation of the component. The existence of the adjustment mechanism allows the position of the second mounting plate to be adjusted through the gear and the rotating ring, which provides convenience for the installation and adjustment of the component to be installed.

[0020] 2. In the present invention, the second mounting plate and the rotating ring are connected through a plurality of locking mechanisms. The locking mechanism between the second mounting plate and the rotating ring can quickly release the fixation when needed. By inserting the insertion ring into the insertion ring, it is used to ensure the fixation of the second mounting plate. By sliding the insertion rod out of the insertion ring, the second mounting plate is released from fixation, and the rotating ring can be driven through the gear and the teeth. Due to the design of the locking mechanism, the second mounting plate can be quickly disassembled from the rotating ring, which is convenient for maintenance and replacement. The quick fixation and release of the second mounting plate enable the device to adapt to different working conditions or different component installation requirements.

[0021] 3. In the present invention, the second mounting plate and the planet carrier are connected through a support mechanism. By extending and retracting the electric telescopic rod, the height of the limiting block is adjusted. After the height is adjusted to the appropriate position, the insertion bolt is inserted into the planet carrier for supporting and positioning the planet carrier. The combined use of the electric telescopic rod and the limiting block can further adjust and fix the position of the planet carrier, ensuring the stable operation of the entire mechanism. The quick and accurate adjustment ability can reduce the downtime of the equipment and improve production efficiency. When the planet carrier needs to be replaced or repaired, it can be done more easily and can be quickly adjusted through the electric telescopic rod and the limiting block.
