Phosphorization prevention device for outer ring raceway of conical bearing

Abstract

The invention discloses a phosphorization prevention device for an outer ring raceway of a conical bearing. The phosphorization prevention device for the outer ring raceway of the conical bearing comprises bearing outer rings, one ends of the two bearing outer rings are attached, the other ends of the bearing outer rings are attached to baffles, a fixing cylinder is installed on the inner wall of one baffle, a connecting bolt is connected to the other baffle in a clamped mode, the connecting bolt is connected with the fixing cylinder, driving rods are clamped to the middles of the baffles, connecting blocks are mounted at one ends of the driving rods and connected with a mounting frame, centering mechanisms are mounted at the other ends of the driving rods, a locking mechanisms are mounted between the outer walls of the driving rods and the baffles, and the baffles are attached to the other ends of the bearing outer rings. Preliminary pre-tightening is carried out through the connecting bolt and the fixing cylinder, the locking mechanisms are opened, the driving rods are rotated, the centering mechanisms carries out self-centering positioning on the bearing outer rings, the two bearing outer rings are completely aligned and limited, then the connecting bolt is completely tightened, and the baffles completely clamps the bearing outer rings, so that the effect that inner cavities of the bearing outer rings are completely sealed is achieved; and the driving rods and the baffles are fixed through the locking mechanisms, and the connecting blocks are connected with the mounting frame, so that the bearing outer rings are overturned and phosphatized conveniently.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to an anti-phosphating device for the outer ring raceway of a tapered bearing. Background technique [0002] The phosphating process is a process of chemical and electrochemical reaction to form a phosphate chemical conversion film, and the formed phosphate conversion film is called a phosphating film. The main purposes of phosphating are: to provide protection for the base metal and to prevent the metal from being corroded to a certain extent; to be used as a primer before painting to improve the adhesion and anti-corrosion ability of the paint film; to reduce friction in the metal cold working process For lubricating use, in the existing bearing processing technology, the outer surface of the outer ring of the bearing is phosphated, and a layer of phosphate film is formed on the surface, which protects the bearing base and prevents corrosion. For tapered bearings, the ...

AI Technical Summary

Problems solved by technology

The purpose of phosphating is mainly to provide protection for the base metal and prevent the metal from being corroded to a certain extent; it is used as a primer before painting to improve the adhesion and anti-corrosion ability of the paint film layer; it can reduce friction in the metal cold processing process For lubricating use, in the existing bearing processing technology, the outer surface of the bearing outer ring is phosphating, forming a layer of phosphating film on the surface, which can provide protection for the bearing matrix and prevent corrosion. For tapered bearings, the raceway of the inner diameter of the outer ring of the bearing cannot be phosphating. The traditional method is to grind the raceway after phosphating and super-finish. The process is complicated, the processing cost is high, and it is difficult to destroy the phosphating film on the outer diameter. To meet the precision requirements of the product, we propose an anti-phosphating device for the outer ring raceway of the tapered bearing to solve the above problems
