Abstract

The invention discloses a tool for a carburization process of a railway bearing, which is capable of ensuring the carburization quality and achieving carburization of a bearing set. The tool comprises a base gasket, a middle partition gasket and a middle gasket, wherein the base gasket comprises a bottom baffle ring, a plurality of bottom outer baffle columns, a plurality of bottom cushion blocks, and bottom inner baffle columns; a plurality of rectangular flanges are evenly distributed on the upper end surface of the bottom baffle ring; the bottom outer baffle columns are evenly distributed on and connected with the outer periphery of the bottom baffle ring; the plurality of bottom cushion blocks are evenly distributed on and connected on the bottom baffle ring; each bottom inner baffle column is arranged on the inner end of each bottom cushion block; the middle partition gasket comprises a middle partition baffle ring, a plurality of middle partition outer baffle columns, a plurality of middle partition cushion blocks, and middle partition inner baffle columns; a plurality of rectangular flanges are evenly distributed on the upper end surface and the lower end surface of the middle partition baffle ring respectively; the middle partition outer baffle columns are evenly distributed on and connected with the outer periphery of the middle partition baffle ring; the middle partition cushion blocks are evenly distributed on and connected with the inner periphery of the middle partition baffle ring; each middle partition inner baffle column is arranged on the inner end of each middle partition cushion block; the middle gasket comprises a middle baffle ring, a plurality of middle cushion blocks and middle inner baffle columns; the middle cushion blocks are evenly distributed and connected on the outer periphery of the middle baffle ring; and each middle inner baffle column is arranged on the inner end of each middle cushion block.

Description

technical field [0001] The invention relates to a tool for the carburizing process of railway bearings. Background technique [0002] Most railway bearings are double-row tapered roller bearings, which consist of an integral outer ring and two inner rings. The small end faces of the two inner rings are similar, and there is a spacer ring in the middle. At present, the carburizing method of railway bearings is mainly gas carburizing. There is no specific tooling for the workpiece during carburizing. Most of the workpieces are carburized separately in a single piece. effective contact. Since the workpiece is carburized separately in a single piece, the capacity of carburizing is small, and the utilization rate of carburizing equipment is low. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a tool for the carburizing process of railway bearings, which can not only ensure the carburizing quality...
