Description
Technical Field
The utility model belongs to the technical field of wind generating set part technique and specifically relates to a wind power generation driftage spacer seamless ring spare.
Background
In the operation process of the wind generating set, in order to improve the generating capacity of the generating set to the maximum extent, the wind machine cabin needs to continuously yaw to realize wind alignment. In order to ensure that the wind generating set stably yaws, the wind generating set generally has certain damping during yaw, and the damping is provided by mutual friction of a yaw brake disc and a friction plate of a brake. The existing spacer bush mounting positions are as follows: the spacer bush is fixedly arranged on the upper end face of the flange, and the outer wall of the spacer bush is fixedly arranged with the yawing brake disc. However, the existing spacer bush is not provided with a positioning device, and the spacer bush and the flange are very large, so that the spacer bush mounting hole is very difficult to align with the flange mounting hole, and the mounting efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides a wind power generation yawing spacer seamless ring piece.
The utility model provides a technical scheme that its technical problem adopted is: a wind power generation yaw spacer seamless ring piece is provided with an annular spacer body, wherein a convex ring is arranged at the inner ring of the spacer body, a plurality of mounting holes and positioning holes are uniformly formed in the spacer body, and 5-7 mounting holes are formed between the two positioning holes at intervals; and a positioning pin is arranged in the positioning hole in a threaded manner and extends out of the lower end face of the spacer sleeve body. When the spacer bush is installed, the positioning pin is inserted into the positioning hole corresponding to the flange, so that the spacer bush mounting hole is aligned with the flange mounting hole conveniently.
Furthermore, the spacer body outer wall is composed of a first straight line part, a transition inclined line part and a second straight line part which are connected in sequence, the outer diameter of the first straight line part is larger than that of the second straight line part, and the second straight line part is located above the first straight line part. The spacer body outer wall sets up like this, can increase the area of contact of driftage brake disc, further improves the firm performance of installation with the driftage brake disc.
Furthermore, an annular oil groove is formed in the spacer sleeve body and is close to the convex ring. The oil groove is filled with lubricating oil, and the lubricating effect of the spacer sleeve is improved.
Furthermore, the upper end face of the positioning hole is provided with a sinking platform for accommodating the positioning pin nut.
The utility model has the advantages that: the utility model has simple structure, reasonable design and simple operation, and the positioning pin is inserted into the positioning hole corresponding to the flange, thus the spacer bush mounting hole is aligned with the flange mounting hole conveniently; the first straight line part, the transition diagonal line part and the second straight line part are arranged, so that the contact area of the yaw brake disc can be increased, and the installation firmness with the yaw brake disc is further improved; the oil groove is filled with lubricating oil, and the lubricating effect of the spacer sleeve is improved.
