Abstract
The utility model discloses a four-row cylindrical roller bearing based on an assembly chamfering angle at an outer ring. The four-row cylindrical roller bearing comprises an outer ring 1, an inner ring 2, rollers 3 and holders 4. The four-row cylindrical roller bearing is characterized in a circular-arc transitional chamfering angle is formed at the outer end side of the outer ring 1; and the chamfering angle extends towards the two sides to form 10-degree slopes respectively. The four-row cylindrical roller bearing based on the assembly chamfering angle at the outer ring disclosed by the utility model has the beneficial effects as follows: firstly, the slopes are used for guiding during the assembling process, so that the installation is convenient, and the inner and outer rings of the bearing, a shaft and a shaft housing are prevented from being damaged; and secondly, the assembling difficulty is lowered due to the change of the bearing chamfering angle.
Description
Technical field
The present invention relates to technical field of bearings.
Background technique
As shown in Figure 1, four-line column roller bearing comprises outer ring 1, inner ring 2, roller 3, retainer 4.Problem is, the installation precision of large-scale four-line column roller bearing has directly determined the kinematic accuracy of rotatingshaft, and therefore how improving installation precision is one of problem that will solve.
Summary of the invention
The convenient bearing of installing of the present invention.
In order to achieve the above object, the invention provides a kind of four-line column roller bearing that assembly chamfer is set based on the outer ring, comprise outer ring 1, inner ring 2, roller 3, retainer 4, described outer ring 1 outer distolateral be the chamfering of arc transition, and described chamfering extends to both sides, forms respectively the slope of 10 degree.
Bearing assemble chamfering of the present invention 10 degree slopes in addition on normal chamfering basis, beneficial effect is:
1, in assembly process, guiding function is played on the slope, and convenient the installation avoided injury to the inside and outside circle of bearing, axle, axle housing.
2, due to the change of bearing chamfer, the characteristics such as assembling difficulty reduction.
Description of drawings
Fig. 1 is the structural representation of four-line column roller bearing of the present invention.
Fig. 2 is A place structure for amplifying schematic diagram in Fig. 1.
Embodiment
Four-line column roller bearing of the present invention, comprise outer ring 1, inner ring 2, roller 3, retainer 4 as illustrated in fig. 1 and 2.Shown in Figure 2, outer ring 1 outer distolateral be the chamfering of arc transition, and described chamfering extends to both sides, forms respectively the slopes of 10 degree.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
