Abstract
The utility model relates to a high temperature zanjon ball bearing comprising of steel ball(2), outer ring(1) and inner ring(3).A groove shaped as circular arc positions on the middle of the width of inner surface of the outer ring(1) and outside surface of the inner ring(3) respectively.A crack is spreaded on the outer ring(1) used as thin-wall bearing, and the inner ring(3) used as non-thin-wall bearing is split structure..The utility model drops the traditional ball bearing retainer, and adopts wider end-play.Therefore, the ball bearing can keep good running under the invasion og higher temperature, thicker dust or dirty gas and sewage, and the service life is prolonged greatly.
Description
Technical field:
The utility model relates to technical field of bearings, is a kind of High-temperature Deep-furrow Ball Bearing specifically.
Background technique:
At widely used High-temperature Deep-furrow Ball Bearings in field such as pottery, machine brick, glass, chemical industry, metallurgy, main accessory as equipment, in the prior art, this bearing generally is that its component all adopt resistant to elevated temperatures special material, as M50, Cr4Mo4V, materials such as W18Cr4VA or heat-resistance stainless steel, the cost costliness, manufacture difficulty is bigger.
Another kind is that CN99252851.8 discloses a kind of High-temperature Deep-furrow Ball Bearing, this bearing is the full dress ball bearing that has filling slot, and use a Steel Cable Baffle Ring, the restriction steel ball breaks away from bearing channel from indentation, there, because of this bearing is big radial internal clearance design, when when the breach direction applies axial force, rough running will appear in bearing, cause the bearing early damage.
The model utility content:
The purpose of this utility model provides a kind of stability of rotation, and can carry the High-temperature Deep-furrow Ball Bearing of certain thrust load.
For achieving the above object, the technical solution adopted in the utility model is as follows: described High-temperature Deep-furrow Ball Bearing, be made up of steel ball, outer ring and inner ring, all have the circular arc raceway groove on inner surface and the inner ring outer surface, its raceway groove position lays respectively at 1/2 place of outer ring and inner race width; The outer ring rise that is used for thin-wall bearing has crackle one; The inner ring that is used for non-thin-wall bearing is a split type structure.Described steel ball (2) diameter D

Specific embodiments:
Diameter dimension series according to bearing can be implemented two kinds of different technological schemes respectively:
Embodiment one: as shown in Figure 1, the utility model comprises outer ring 1, steel ball 2, inner ring 3, the shape and structure of outer ring 1 and inner ring 3 is respectively shown in Fig. 2,3,1/2 place of the width direction of outer ring 1 internal surface, inner ring 3 outer surfaces has a corresponding mutually circular arc raceway groove, and one group of steel ball 2 is contained between the raceway groove of outer ring 1 and inner ring 3.Steel ball size D
wBe 25%～32% of the difference of outer ring outer diameter D minus inner ring inner diameter d, outer ring raceway section radius R
eWith bear inner ring grooved railway section radius R
iBe steel ball size D
w0.51～0.55 times, and outer ring raceway section radius R
eGreater than bear inner ring grooved railway section radius R
i, guaranteed shaft strength after, Internal and external cycle has equal contact strength, prolongs the working life of bearing.Go up and have crackle one in outer ring (1), in order to load steel ball 2, total backlash is steel ball size D between steel ball
w0.2～0.4 times.Embodiment one is applicable to the thin-wall bearing outer ring.
Embodiment two: roughly the same with embodiment one structure as Fig. 4, Fig. 5, shown in Figure 6, just inner ring 3 is a split type structure, is not subjected to the influence of bearing diameter dimension series size; Outer ring 1 raceway groove section radius R
eWith inner ring 3 raceway groove section radius R
I1With R
I2Be combined as steel ball size D
w0.51～0.55 times.Embodiment two is applicable to non-thin-wall bearing.
Claims (2)
1, a kind of High-temperature Deep-furrow Ball Bearing, be made up of steel ball (2), outer ring (1) and inner ring (3), all have the circular arc raceway groove on outer ring (1) internal surface and inner ring (3) outer surface, it is characterized in that: described raceway groove position lays respectively at 1/2 place of outer ring (1) and inner ring (3) width; Outer ring (1) rise that is used for thin-wall bearing has crackle one; The inner ring (3) that is used for non-thin-wall bearing is a split type structure.
2, High-temperature Deep-furrow Ball Bearing according to claim 1 is characterized in that: described steel ball (2) diameter D
