Abstract

The invention provides a wear-resistant pad of a carriage connecting device. The wear-resistant pad with high compression resistance and high wear resistance is additionally arranged on a worn surface of the carriage connecting device. Compared with the prior art, the wear-resistant pad can protect a car coupler knuckle and a ball bearing bush body from wear and ensure that the tensile strength of the coupler knuckle and the ball bearing bush is constant throughout, and further has the advantages of rapid and convenient maintenance and replacement, low cost, safe running, and the like.

Description

A kind of wear-resistant pad of carriage connecting device

The present invention relates to a kind of wear-resistant pad of carriage connecting device.At present the connecting device between the railcar has two kinds of versions, and a kind of is to rely on the two hook tongues that are contained in the two compartment tail frames positive and negative interlocking and connecting mutually.Another kind is the ball bearing shell in relying on the ball axle be contained in the compartment tail frame and being contained in another tail frame and being connected.Because of carrying pulling force and the impact more than 400 tons between hook tongue and hook tongue and ball axle and the ball bearing shell, and rub up and down mutual friction mutually with ball axle and ball bearing shell of two hook tongues under fully loaded transportation condition, cause severe wear between two hook tongue S faces and ball axle and the ball bearing shell, its tensile strength reduces greatly, nearly 2,000,000 hook tongues of full railway line and ball bearing shell are cracked more than 8～10% even ruptures.Bring very big harm to traffic safety.

The way that solves at present hook fissuring of tongue and fracture is at the frayed S face of hook tongue, and electricity consumption slag muck postwelding increases its thickness and regularly replaces the ball bearing shell with the way of copy milling again guarantees traffic safety.The hook tongue is repaired with electroslag surfacing, and the repairing difficulty is big, and efficient is low.Electric welding also can cause harmful effect to the performance of hook tongue material.Ball bearing shell periodic replacement waste is very big, the cost height.Number of patent application is the difficult problem that 200620149984 hitch also fails to solve the hitch severe wear.

Purpose of the present invention is will provide thoroughly to solve the wear-resistant pad that hook tongue severe wear and ball bearing shell need not regularly replace in the carriage connecting device.

For reaching this purpose, the present invention sets up the wear-resistant pad of a floor height resistance to compression, high abrasion at the flour milling that is subjected to of carriage connecting device.Compare with prior art, a car coupler knuckle and ball watt axle body is not is not worn and torn, and can guarantee that hook tongue and ball bearing shell tensile strength are constant all the time, and safeguard and change efficient and conveniently that cost is low, advantages such as traffic safety.

Be described further below in conjunction with exemplary embodiments and accompanying drawing:

Fig. 1 is for setting up the principle assumption diagram of wear-resistant pad at the frayed place of hook tongue S face;

Number in the figure and title are as follows:

1-hook tongue 2-wear-resistant pad 3-ball bearing shell 4-clench nail

The right binding 7-of 5-left side binding 6-cydariform ball 8-ball journal

In Fig. 1 and Fig. 2, hook tongue (1) is loaded in the compartment tail frame with axle by its circular hole, is subjected to the mill place at the S face of hook tongue (1), the wear-resistant pad of manufacturing with nonmetallic composite (2) of glued one deck suitable thickness and shape.With this hook tongue (1) mutually the S face of another hook tongue of hook do not set up the wear-resistant pad of manufacturing with non-metallic material (2); Also can be subjected to mill place heat spraying method at the S face of hook tongue (1), the wear-resistant pad (2) with wear resistant alloy material of spraying one deck suitable thickness and shape is so that constitute a pair of wear-resisting pair.

In Fig. 3 and Fig. 4, ball face in two semicircular ring ball bearing shells (3), set up the global shape wear-resistant pad (2) that one deck is manufactured with non-metallic material, the left and right end face of two spherical ball bearing shells of semicircular ring (3), with annular arrangement left side binding (5) and right binding (6), being fixed on outside face by clench nail (4) does not have on the outer circle of drum type ball (7) of wear-resistant pad (2), so that non-metal and metal constitute a pair of fastness; Also can set up the global shape wear-resistant pad (2) that one deck is manufactured with non-ferrous metal material at the interior ball face of two semicircular ring ball bearing shells (3); Or with adding the annular wear-resistant pad (2) that materials such as graphite, molybdenum disulphide are manufactured in the non-metals.

The circular shaft that ball bearing shell (3) after the assembling constitutes by its periphery; Being loaded on the compartment connects with in the annular arrangement circular hole in the tail frame.Cydariform ball (7) is fixed in two semicircular ring ball bearing shells (3), and is fixed in the U-shaped frame of connection with the tail framework in another compartment by the ball journal (8) on its both sides.

In Fig. 6 and Fig. 5, structural principle is with Fig. 3 and Fig. 4, and difference is: the interior ball face at two semi-ring ball bearing shells (3) is a metallic material.And, set up the wear-resistant pad (2) that one deck is manufactured with non-metallic material, so that metallic material and non-metallic material constitute a pair of fastness at the periphery of cydariform ball (7); Also can set up the wear-resistant pad (2) that one deck is manufactured with non-ferrous metal material at the cylindrical anchor ring of cydariform ball (7); Or be used in and add the wear-resistant pad (2) that materials such as graphite, molybdenum disulphide are manufactured in the non-metals.
