Vibration reduction spherical crown lining plate with lubricating grease supplementing function

Abstract

A vibration reduction spherical crown lining plate with a lubricating grease supplementing function comprises a top plate, a spherical panel, a vibration reduction body and a grease supplementing body, a mounting groove used for mounting the top plate is formed in the upper surface of the spherical panel, and a plurality of vibration reduction upper grooves and grease supplementing upper grooves used for mounting the vibration reduction body and the upper end of the grease supplementing body are formed in the lower surface of the top plate; a plurality of vibration reduction lower grooves and grease supplementing lower grooves used for installing the vibration reduction body and the lower end of the grease supplementing body are formed in the groove bottom of the installation groove, the vibration reduction body is composed of a vibration reduction guide column on the upper portion and an elastic element on the lower portion, and the grease supplementing body is composed of a grease supplementing guide column on the upper portion and a grease storage deformation element stored with lubricating grease on the lower portion. A plane friction pair grease guiding channel enabling the top face of the top plate to be communicated with the bottom face of the grease supplementing guide column is formed in the grease supplementing guide column and the top plate, and a spherical friction pair grease guiding channel enabling the lower grease supplementing groove to be communicated with the bottom face of the spherical face plate is formed in the bottom of the spherical face plate. The vibration reduction spherical crown lining plate has the damping effect and has the function of supplementing lubricating grease in the using process.

Description

technical field [0001] The invention relates to the technical field of bridge bearings, in particular to a shock-absorbing spherical crown liner with the function of replenishing lubricating grease. Background technique [0002] The spherical crown liner, also known as the middle seat plate, is a key component to realize the rotation and plane movement of the spherical bearing. The spherical part of the spherical crown liner is used as a hard grinding surface and is directly exposed to the working environment. It must have good wear resistance and good corrosion resistance to meet the design requirements for long-term and stable service. [0003] At present, the main body of the spherical crown liner is mostly made of low alloy steel, aluminum alloy and other materials. In order to ensure the corrosion resistance and wear resistance of the hard grinding surface, the spherical surface of the low-alloy steel spherical crown liner needs to be coated with stainless steel plate ...

AI Technical Summary

Problems solved by technology

The low-alloy steel spherical crown liner clad stainless steel plate molding process is extremely difficult to implement, and there are often problems such as the joint between the stainless steel plate and the spherical crown liner is not tight, and the weld seam at the joint is corroded; and the surface of the spherical crown liner is seriously chrome-plated. The pollution problem does not meet the current low-carbon environmental protection requirements

The use of aluminum alloys is costly and complicated

[0004] The spherical crown liner is usually made of a solid structure and a single material. Its structure is simple, its weight is heavy, and its actual use stress is relatively low, so it cannot give full play to the mechanical properties of the material.

[0005] In addition, the structure of the traditional spherical crown liner is too simple, the function is simple, and the structural position advantage of this part in the support cannot be fully utilized.

At present, most of the grease in the spherical bearing is stored in the grease storage pit of the skateboard. When all the grease in the disposal pit is lost, the skateboard will enter a dry friction state, which will seriously affect the service life of the skateboard. The friction pair of the bearing provides grease replenishment

In addition, the vibration damping and isolation function of bridges has become a necessary option for municipal and intercity projects. At present, vibration damping supports usually require an additional layer of vibration damping material or structure outside the support structure, which increases the height of the support and is complicated.
