Problems solved by technology

[0002] The main shaft bearing of wind turbines with a power of 600KW or more weighs more than 200Kg. Generally, it is hoisted by a crane and installed on a vertically placed main shaft. If the bearing level is not adjusted well, the heated bearing will often be adjusted for too long and the bearing temperature will drop. , causing the installation to fail

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0013] As shown in Figures 1 and 2, the present embodiment includes a suspension ring 1, a disk 2, a suspension rod 3, a tension hook 4, and a bearing clamping ring 5, and the bearing clamping ring is divided into two semicircular rings ( image 3 ). The bearing clamping ring 5 is an annulus formed by connecting two half annuli with a bolt. Four lifting lugs are evenly distributed on the circumference of the bearing clamping ring. The bore diameter of the bearing clamping ring is slightly smaller than the bearing diameter. Four tensioning hooks 4 pass through the four lifting lugs evenly distributed on the circumference of the bearing clamping ring 5, the upper ends of the four tensioning hooks 4 are connected to the lower ends of the four suspension rods 3, and the upper ends of the four suspension rods 3 are connected to the disc 2 Connection, the suspension ring ...

Abstract

The invention relates to a device for mounting a wind-driven generator main shaft bearing, which comprises a hoisting ring, a circular disk, hoisting rods, a tension hanging hook and a bearing clamp ring. The device is characterized in that the hoisting ring is arranged in the center of the circular disk; the hoisting rods are all arranged on the periphery of the circular disk; the lower ends of hoisting rods are connected with the tension hanging hook; and the bearing clamp ring is hung on the tension hanging hook. By adopting the structure, the bearing clamp ring is connected with a clamping bearing by bolts through two half circular rings, the hoisting ring can hoist a bearing after being hung on a crane, a leveling rod is placed on the hoisted bearing surface, and the tension hanging hook makes left and right tooth screw hole tighten or loosen the hoisting rods by rotating, so as to conveniently solve the problem of adjusting the levelness of the bearing surface, and ensure that the structure is more reasonable.

Description

technical field [0001] The invention relates to the technical field of wind power generator production, in particular to a device for installing a wind power generator main shaft bearing. Background technique [0002] The main shaft bearing of wind turbines with a power of 600KW or more weighs more than 200Kg. Generally, it is hoisted by a crane and installed on a vertically placed main shaft. If the bearing level is not adjusted well, the heated bearing will often be adjusted for too long and the bearing temperature will drop. , causing the installation to fail. The object of the present invention is to provide a device, especially for improving the efficiency and quality of installing the main shaft bearing of the wind power generator. Contents of the invention [0003] The purpose of the present invention is to provide a wind power generator main shaft bearing installation device with reasonable structure and easy adjustment of the levelness of the bearing surface. ...
