Abstract
A high-temperature resistant bearing comprises an outer ring, steel balls, an inner ring, and semi-holding racks. The inner ring is sleeved in the outer ring; circles of grooves are formed at the middle parts along the inner circle wall of the outer ring and the excircle wall of the inner ring, and a circle of steel balls are filled in the space between the two grooves; the two semi-holding racksare riveted together through rivets; and the steel balls are in the bag hole of the semi-holding racks. The bearing further comprises a dust cap and a seal ring made of fluoro-rubber; a circle of outer groove is formed along the inner circle wall of the outer ring and a circle of inner groove is formed along the excircle wall of the inner ring; both the dust cap and the seal ring are jointed withthe inner groove and are in clearance fit with the outer groove; and high-temperature resistant grease is filled in the cavity between the dust cap and the steel balls. The outer ring, the steel balls, and the inner ring of the high-temperature resistant bearing are all made of bearing steel through high-temperature tempering and stabilizing treatment, so that the bearing has the advantages of long service life and high-temperature resistance, can continuously run under the temperature of 250 DEG C in a long term, and can run under the temperature of 280 DEG C in a short term.
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 have a circle outer channel along the inner round wall face of outer ring, the cylindrical wall of inner ring has a circle internal channel, and described dust cover and seal ring and described internal channel are fitted and the outer channel Spielpassung; 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 and handle through manganese phosphate outer ring, steel ball, the inner ring of making by Bearing Steel and through high-temperature tempering, stabilization.Have corrosion protection, antirust effect.
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.Bearing described in the utility model is mainly used in biaxial tension chain folder bearing.
