Description

Double-force bearing

Technical Field

The utility model belongs to the technical field of the bearing, concretely relates to double-force bearing.

Background

According to the property structure formed by mechanical equipment, the stress of the middle shaft of the mechanical equipment is divided into three working states of axial stress, radial stress and axial and radial simultaneous stress, and meanwhile, according to the difference of the bearing force and the rotating speed, the conventional bearing can be roughly divided into the following 6 series products:

class 1: the bearing is suitable for a thrust ball bearing with low strength and high-speed running and axial stress;

class 2: the thrust cone bearing is suitable for high-strength low-speed running axial stress;

class 3: the bearing is suitable for a deep groove ball bearing with low strength and high speed running and radial stress;

class 4: the bearing is suitable for a cylindrical roller bearing with high strength and low speed running and radial stress;

class 5: the bearing is suitable for a tapered roller bearing which runs at high strength and low speed and is stressed in the radial direction and the axial direction simultaneously;

class 6: the bearing is suitable for angular contact bearings and four-point contact ball bearings which are in low-strength and high-speed operation and are stressed in radial and axial directions simultaneously; in some special application fields which bear larger axial load and larger radial load, the bearing depth is required

The above 6 types of bearings can basically meet most of the application fields of mechanical equipment, but the two types of bearings, namely the groove ball type bearing and the thrust ball type bearing, are jointly stacked together and used as one bearing, so that the use problem is solved, but the congenital design defects of large size, heavy weight, heavy equipment and the like exist.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a double force bearing.

The utility model adopts the following technical scheme for accomplishing the above purpose:

a double-force bearing comprises a race, wherein an annular raceway for limiting an axial rolling body is arranged on the upper end face of the race, an axial retainer is placed on the race, a plurality of through holes for placing the axial rolling body are formed in the axial retainer, the lower portion of the axial rolling body placed on the axial retainer is positioned in the annular raceway of an inner ring, the inner ring is placed on the retainer, an annular boss protruding inwards is arranged on the lower portion of the inner wall face of the inner ring, the section shape of the inner ring with the annular boss is L, the annular raceway matched with the axial rolling body is arranged on the lower end face of the inner ring, and a radial rolling body is arranged between the inner ring and the outer ring.

And annular roller paths matched with the radial rolling bodies are arranged on the outer wall surface of the inner ring and the inner wall surface of the outer ring.

And a radial retainer is also arranged between the inner ring and the outer ring.

The utility model provides a pair of double force bearing adopts the inner circle that cross sectional shape is L shape, sets up the axial rolling element between inner circle and seat circle, sets up radial rolling element between inner circle and outer lane, has solved current two sets of bearing stack and has used the problem that the weight is huge, the weight is heavy that brings as one set together.
