Description

Technical Field

[0001] This utility model relates to the field of bearing support technology, specifically a high wear-resistant bearing support structure. Background Technology

[0002] Bearing supports generally operate at room temperature and are non-moving parts, primarily bearing vibration loads and compressive stress. From a performance perspective, to minimize these effects, gray cast iron blanks should be used. The graphite structure buffers mechanical vibrations, preventing the propagation of vibration energy and eliminating the vibration source within the flake graphite. Gray cast iron also has strong compressive strength. In terms of casting performance, gray cast iron has the best fluidity and the lowest shrinkage rate. Considering all factors, HT150 gray cast iron is the most suitable and is generally used to cast supports, bases, gearboxes, worktables, etc.

[0003] However, existing high wear-resistant bearing support structures have the following problems during use: traditional bearing supports require bolt fixing during installation, resulting in long installation time and low installation efficiency. In addition, bearing supports are easily worn parts, which leads to a short service life. Utility Model Content

[0004] The purpose of this invention is to provide a highly wear-resistant bearing support structure to solve the related problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly wear-resistant bearing support structure, comprising a base plate, legs, and an arc-shaped fixing frame. The top of the base plate is fitted with a leg, and the top of the leg is fitted with a fixed base. Positioning screws are installed on both sides of the top of the fixed base, and the outer wall of the positioning screw is fitted with the arc-shaped fixing frame. A rigid spring is fitted on the outer wall of the positioning screw, and the top of the rigid spring contacts the bottom of the arc-shaped fixing frame. A nut positioning block is provided on the outer wall of the positioning screw. A limiting mechanism for fixing the position of the nut positioning block is provided inside the positioning screw. An upper fixing block is provided on the inner wall of the arc-shaped fixing frame, and a positioning groove is formed on the outer wall of the upper fixing block. A lower fixing block is provided at the top of the fixed base, and a positioning post penetrating the positioning groove is installed at the top of the lower fixing block. Reinforcing wear-resistant mechanisms are provided on the inner walls of the arc-shaped fixing frame and the fixed base, respectively contacting the lower fixing block and the upper fixing block.

[0006] This technical solution provides a high wear-resistant bearing support structure, wherein a connecting groove is provided at the bottom end of the base plate.

[0007] This technical solution provides a high wear-resistant bearing support structure. The limiting mechanism includes a movable groove and a sliding groove. The movable groove is provided inside the positioning screw, and the sliding groove is installed on the inner wall of the movable groove.

[0008] This technical solution provides a high wear-resistant bearing support structure, wherein the movable groove is provided with a positioning protrusion that penetrates the positioning screw and extends to the bottom of the nut positioning block, and a return spring is provided between the inner walls of the positioning protrusion.
