Self-lubricating friction-reducing sliding bed plate

Abstract

The invention provides a self-lubricating friction-reducing sliding bed plate, being characterized in that a square groove (2) is arranged on the upper end face of a sliding bed table (1); a wear-resisting self-lubricating plate (4) is embedded into the square groove (2); front, rear, left, right and lower directions of the wear-resisting self-lubricating plate (4) are positioned by the square groove (2), and the upper surface of the wear-resisting self-lubricating plate (4) is protruded from the upper end face of the sliding bed table (1); the square groove (2) is a rectangular groove, and one side of the rectangular groove is provided with a notch (3); the wear-resistant self-lubricating plate (4) is a rectangular structure formed in one step; and the wear-resistant self-lubricating plate (4) and the square groove (2) are bonded together by an adhesive, so that the wear-resisting self-lubricating plate (4) and the sliding bed table become an integral whole. The invention simplifies the structure of the sliding bed table, has lower manufacturing cost and high production efficiency; the wear-resistant self-lubricating plate is made of modified polytetrafluoroethylene, which can effectively reduce the surface friction coefficient of sliding table, and its wear resistance and plastic creep resistance can meet the requirements of the tip rail.

Description

technical field [0001] The invention belongs to the technical field of railway turnouts, and in particular relates to a self-lubricating anti-friction sliding bed plate. Background technique [0002] The sliding bed plate is a backing plate that supports the basic rail and slides the switch rail, and is an indispensable part in the turnout. During the switching process of switch rails, friction between the bottom of the switch rail and the sliding bed will inevitably occur, resulting in resistance. How to reduce friction and easily realize switching of switch rails is one of the mid-term and long-term research topics in the research and development of turnout products. At present, the methods adopted include technologies such as oiling, anti-friction coating on the sliding bed, and roller sliding bed. [0003] In order to reduce the pulling resistance of the turnout point rail and environmental pollution, reduce costs, etc., the applicant applied for a self-lubricating slid...

AI Technical Summary

Problems solved by technology

The polytetrafluoroethylene anti-friction plate is easy to stick to the knife during processing, and the processing is difficult. The matching slide table is designed with a dovetail groove for installing the anti-friction plate, and two M6 threaded holes are designed at the rear end of the platen for fixing The anti-friction plate makes the structure of the sliding bed complex, and the processing workload and manufacturing cost increase

When in use, it is necessary to regularly check the state of the screws, which increases the labor load of the daily maintenance of the workers.
