Problems solved by technology

The forming process of stainless steel skateboard includes blanking, forming, welding and even grinding. Different molds need to be manufactured according to different forming sizes. When forming large-sized stainless steel, special large-scale forming equipment is required. The forming process is complex, difficult and low in forming efficiency.
When the sliding or rotating surface of the support is chrome-plated, the electrolyte used in the chrome-plating process is composed of highly toxic chromic anhydride. During the chrome-plating process, 2 / 3 of the chromic anhydride is consumed in waste water or waste gas. A large amount of waste water and waste gas are harmful to the environment. caused serious pollution

Abstract

The invention provides a bridge support with a novel friction pair. A friction-reducing, wear-resisting and corrosion-resisting ceramic material is molded on rotary and sliding surfaces of the bridge support; and the material and a non-metal sliding plate form the novel friction pair of the bridge support.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, and relates to a bridge bearing with a novel friction pair. Background technique [0002] Bridge bearings as "bridge joints" have been used on a large scale in bridge projects such as highways and railways. As the core component of the bearing, the friction pair can realize the sliding and rotating functions of the bearing. Therefore, it is required that the friction pair must have low friction coefficient, high wear resistance and excellent corrosion resistance. [0003] At present, the friction pairs used in bridge bearings are composed of stainless steel plates or hard chrome plated and polytetrafluoroethylene or ultra-high molecular weight polyethylene slide plates. The forming process of stainless steel skateboard includes blanking, forming, welding and even grinding. Different molds need to be manufactured according to different forming sizes. When forming large-sized stainless...
