Abstract
A high temperature resistance bearing includes an internal ring, a steel ball, an internal ring and half cages. The internal ring is sleeved with the internal ring; a ring of troughs are separately arranged along the middle part of the internal round wall surface of the external ring and the external round wall surface of the internal ring; a ring of steel balls are filled between two grooves; the two half cages are riveted by the rivets; the steel balls are positioned in the holes of the two half cages; the utility model also includes a dustproof cover and a sealing ring made of a fluororubber; a ring of troughs are separately arranged along the two sides of the internal round wall surface of the external ring and the external round wall surface of the internal ring; the dustproof cover and the sealing ring are jointed to the grooves; high temperature resistance grease is filled in an empty chamber between the dustproof cover and the steel ball. The external ring, the steel ball, and the internal ring, of the utility model, are the bearing steel and are made by the processing of high temperature tempering and stabilization. The utility model has the advantages of long service life, high temperature resistance, and is able to continuously run for long time under the condition of high temperature of 250 DEG C and to run in short time under the condition of high temperature of 280 DEG C. The utility model is mainly applied to bidirectionally extend the chain bearing.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of high temperature resistant bearing.
Background technique
Deep groove ball bearing is simple in structure, and working service is convenient.Be mainly used to bear radial load, also can bear certain axial load, when the radial internal clearance of bearing strengthens, have the performance of angular contact ball bearing, can bear bigger axial load.This class bearing frictional resistance is little, and the limit speed height is adapted to run up.
But, the adaptation running temperature-30 of present deep groove ball bearing ℃ between+120 ℃, non-refractory.At high temperature, the ball of present deep groove ball bearing often under the heat expansion effect, can be stuck in Internal and external cycle and can not use or the life-span extremely short, this has obviously hindered the more extensive utilization of deep groove ball bearing.
For this reason, notification number is that the Chinese patent of CN2392027 discloses a kind of High-temperature Deep-furrow Ball Bearing, comprise outer ring, steel ball, inner ring and Steel Cable Baffle Ring, suit inner ring in the outer ring, inner round wall face along the outer ring respectively has a circle corresponding rolling arc groove mutually with the intermediate portion of the cylindrical wall of inner ring, loading a circle steel ball between two grooves, and on Internal and external cycle one side wall surface, have a ball-loading hole, the round wall of the inner ring of that side of ball-loading hole or outer ring has draw-in groove, and inlay card has Steel Cable Baffle Ring in the draw-in groove.But this still can not satisfactorily resolve the problem of deep groove ball bearing continuous operation at high temperature.
The model utility content
The purpose of this utility model is to provide a kind of high temperature resistant bearing, to solve the problems referred to above that present bearing exists.
The utility model solves the problems referred to above by the following technical programs, reaches the purpose of this utility model.
A kind of high temperature resistant bearing comprises outer ring, steel ball, inner ring, half retainer; Suit inner ring in the outer ring; Intermediate portion along the cylindrical wall of the inner round wall face of outer ring, inner ring respectively has a circle groove, is loading a circle steel ball between two grooves; Described two and half retainers by closing-up together, steel ball is in two and half retainer pocket holes; It is characterized in that: also comprise dust cover and the seal ring of making by fluorine rubber, and respectively have a circle groove, described dust cover and seal ring and the applying of described groove along the both sides of the cylindrical wall of the inner round wall face of outer ring, inner ring; Be filled with high temperature-resistant grease in the cavity between described dust cover and steel ball.
Outer ring of the present utility model, steel ball, inner ring are for handling outer ring, steel ball, the inner ring of making by Bearing Steel and through high-temperature tempering and stabilization.
Owing to adopted design proposal as above, the utlity model has following advantage: long-life high-temperature resistant, can under 250 ℃ of conditions of high temperature, long-time continuous turn round, can short-time running under 280 ℃ of conditions.The utility model is mainly as biaxial tension chain bearing.
