Description

Technical Field

[0001] The utility model relates to the technical field of a balance beam gear box, in particular to an anti-wear mechanism for a guide sleeve of a balance beam. Background Art

[0002] Gearboxes are widely used, for example, in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transfer the power generated by the wind rotor to the generator and make it reach the corresponding speed. Usually, the speed of the wind rotor is very low, far from the speed required by the generator. It must be achieved through the speed increase of the gear pair of the gearbox, so the gearbox is also called a speed increaser.

[0003] At present, the unit production has single-branch and multi-branch production due to different specifications. When producing a single branch, the steel pipe is not in the center position, which causes eccentric wear on the balance beam gear box sleeve. Therefore, there are the following disadvantages: long-term wear can easily cause the steel pipe to slide due to shaking, causing scratches on the surface zinc layer. Eccentric wear will also accelerate the wear of the guide sleeve and cause tooth disengagement failure. Utility Model Content

Bolts are respectively threadedly connected inside the two second threaded holes, and the threaded ends of the two bolts are respectively threadedly connected to the inside of the two threaded grooves.

Through the sliding groove and the sliding block, it is beneficial to limit the mounting ring and prevent the mounting ring from shifting, improving the stability of the mounting ring during movement.

[0014] Third, during use, the bearing is beneficial to support the rotating shaft, making the rotation of the rotating shaft and the auxiliary wheel more smooth and efficient.

[0027] In use, the sliding grooves 12 and the sliding blocks 13 are beneficial for limiting the mounting ring 5, preventing the mounting ring 5 from shifting, and improving the stability of the mounting ring 5 during movement. The bearings 14 are beneficial for supporting the rotating shafts 7, making the rotation of the rotating shafts 7 and the auxiliary wheels 6 smoother and more efficient.
