Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] see Figure 1 to Figure 4b , the carburizing tray of the bearing ring of the present invention comprises a bottom tray 1, a middle tray 2 and an upper tray 3 connected by four positioning columns 4 and four load-bearing columns 5; the bottom tray 1, the middle tray The shape and size of the disc 2 and the upper tray 3 are the same and each is loaded with four bearing rings 6 evenly distributed. The thickness of the middle layer material tray 2 and the upper layer material tray 3 is the same and less than the thickness of the bottom layer material tray 1 .

[0030] The bottom material tray 1 is composed of several horizontal connecting plates and several longitudinal connecting plates to form a mesh plate with a square mesh. The intersection of the horizontal connecting plates 11 and the longitudinal connecting plates 12 is also provided with a hole seat 10; Each co...

Abstract

The invention discloses a carburizing charging tray for bearing rings. The carburizing charging tray comprises a bottom layer charging tray, a middle layer charging tray and an upper layer charging tray, wherein the bottom layer charging tray, the middle layer charging tray and the upper layer charging tray are respectively and uniformly loaded with the four bearing rings; four lower bearing column bases are arranged on the bottom layer charging tray, each lower bearing column base is provided with a reinforcing structure, and the reinforcing structure comprises two inner rib plates, a lower bearing rod and two lower reinforcing rib plates; the inner side surface of a transverse connecting plate and the inner side surface of a longitudinal connecting plate located on the peripheral edge ofthe bottom layer charging tray are provided with horizontal edge rib plates at half height; four upper bearing column bases are uniformly distributed on the middle layer charging tray and the upper layer charging tray, each upper bearing column base is provided with an upper reinforcing structure, and the upper reinforcing structure comprises three pairs of upper reinforcing rib plates; and partitions, in contact with the four bearing rings, of the middle layer charging tray and the upper layer charging tray are locally widened to 2.5-4.5 times the width of the bottom wall thickness of the bearing rings. According to the carburizing charging tray for the bearing rings, the deformation of the bearing rings can be reduced, and the deformation and cracking of the bearing column bases are reduced.

Description

technical field [0001] The invention relates to a carburizing tray of a bearing ring. Background technique [0002] The carburizing heat treatment process belongs to a kind of surface treatment of parts. Its mechanism of action is to crack propane / acetone and other enriched gases containing large amounts of carbon atoms at high temperature to generate active carbon atoms. Through the diffusion of carbon atoms on the surface of parts, The purpose of carburizing the surface of parts. The carburizing treatment of bearing rings generally adopts heat treatment equipment such as multi-purpose furnace, pit furnace or continuous furnace. During its operation, the bearing rings need to be placed on a special carburizing tray. Prevent the bearing rings from falling and touching each other, which will affect the quality of carburizing and the normal operation of the equipment. Since the carburizing tray is made of high-temperature-resistant and carburizing-resistant alloy steel and ...
