Description

Technical Field

[0001] The utility model relates to the technical field of bearing manufacturing and assembly, in particular to a flat pad for a retainer of an extra-large wind power single-row cylindrical roller bearing. Background Art

[0002] There is no corresponding special tooling at the user's installation, disassembly and maintenance site. When the super-large wind power single-row cylindrical roller bearing is placed horizontally, the roller installed in the cage may be squeezed and worn with the outer ring of the bearing, resulting in deformation and jamming. Since the cage is relatively thin and the roller is installed in the cage, it is easy to cause the cage to deform and jam. Moreover, placing it directly on the ground will cause the outer sleeve and the inner ring groove to jam each other. Therefore, a special tooling is needed to protect the cage at the user's installation, disassembly and maintenance site. Utility Model Content

DETAILED DESCRIPTION

[0014] In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] See attached Figure 1-3The wind power single-row cylindrical roller bearing retainer has a flat pad, including a first connecting rod 1 and a second connecting rod 2, the first connecting rod 1 and the second connecting rod 2 have the same width and length; the first connecting rod 1 and the second connecting rod 2 are cross-connected; two outer platforms and two inner platforms are arranged on the front of the first connecting rod 1, and two outer platforms and two inner platforms are arranged on the front of the second connecting rod 2; the two outer platforms 2-1 on the first connecting rod and the two outer platforms 2-2 on the second connecting rod are in contact with the end face of the outer ring of the bearing, and the two inner platforms 3-1 on the first connecting rod and the two inner platforms 3-2 on the second connecting rod are in contact with the end face of the bearing retainer.

[0016] Furthermore, the center distance between the two outer platforms 2-1 on the first connecting rod and the first connecting rod 1 is L1, and the center distance between the two inner platforms 3-1 on the first connecting rod and the first connecting rod 1 is L2; ​​the center distance between the two outer platforms 2-2 on the second connecting rod and the first connecting rod 2 is L1, and the center distance between the two inner platforms 3-2 on the second connecting rod and the first connecting rod 2 is L2; ​​L1 is greater than L2.

[0017] Furthermore, the two outer stages 2-1 on the first connecting rod and the two outer stages 2-2 on the second connecting rod are raised truncated cones with the same height and diameter, and match the outer ring of the bearing; the two inner stages 3-1 on the first connecting rod and the two inner stages 3-2 on the second connecting rod are raised truncated cones with the same height and diameter, and match the bearing retainer.

[0018] Furthermore, two radial rectangular sliding long holes near the two ends are respectively provided on the first connecting rod 1 and the second connecting rod 2. The two outer platforms 2-1 on the first connecting rod and the two inner platforms 3-1 on the first connecting rod move in the sliding long hole of the first connecting rod 1, and the two outer platforms 2-2 on the second connecting rod and the two inner platforms 3-2 on the second connecting rod move in the sliding long hole of the second connecting rod 2.

[0019] Furthermore, the first connecting rod 1 or the second connecting rod 2 is a thin steel sheet with elasticity, a screw is arranged at the center of the front side of the first connecting rod 1, and a bolt is arranged at the center of the back side of the second connecting rod 2, and the screw matches the bolt.

[0020] Beneficial effects: The utility model is applied to the installation, disassembly and maintenance of super-large wind power single-row cylindrical roller bearings. The super-large wind power single-row cylindrical roller bearing is placed horizontally on the utility model. When the outer ring of the bearing contacts the outer platform, the bearing retainer also contacts the inner platform. The roller installed in the retainer will not be squeezed and worn by the outer ring of the bearing to cause deformation and jamming; the inner ring of the bearing is composed of an inner ring upper part and an inner ring lower part. When disassembly is required, the connecting parts of the inner ring upper part and the inner ring lower part of the horizontal bearing are removed, the inner ring lower part is removed, and then the inner ring upper part is removed. During the disassembly process, since the roller and the retainer are placed on the inner platform, the position change of the inner ring will not affect the position of the roller and the retainer. After disassembly, the roller and the retainer are still placed on the inner platform, and the outer ring is still placed on the outer platform. Similarly, when installation and maintenance are required, the super-large wind power single-row cylindrical roller bearing is placed horizontally on the utility model, which can avoid the problem of deformation and jamming of the retainer due to the relatively thin retainer and the roller installed in the retainer.

[0021] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
