Abstract
The utility model relates to a needle bearing. The needle bearing is a combined bearing and comprises a ferrule, a needle roller, a first retainer, a second retainer, a steel ball, a gasket and an outer housing, wherein the needle roller is mounted on the first retainer and further mounted in the internal diameter of the ferrule together with the first retainer; the steel ball is mounted on the second retainer and is further mounted between the end surface of the ferrule and the gasket together with the second retainer; and the outer housing is used for connecting the ferrule and the gasket. Compared with the prior art, the needle bearing has the advantages of less noise, long service life, compact structure, high reliability, wide application range and adaptability, easiness in mounting and the like.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of needle bearing.
Background technique
Requirement can be born the more and more of joint load bearing in actual use, but simultaneously to the space of bearing intensity, installation, simple, noise requirement, life requirements, carrying etc. are installed corresponding requirement are also arranged.And existing bearing can only singlely be installed, alignment error, installing space are also large, and combination property is not strong.
The model utility content
The purpose of this utility model be exactly provide in order to overcome the defect that above-mentioned prior art exists that a kind of noise reduction is little, long service life, compact structure, reliability are high, applied range, wide adaptability, easy-to-install needle bearing.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of needle bearing, this bearing is combined bearing, it is characterized in that, described needle bearing comprises lasso, needle roller, the first retainer, the second retainer, steel ball, packing ring and outer cover, after described needle roller is arranged on the first retainer, together with the first retainer, be arranged in the internal diameter of lasso, after described steel ball is arranged on the second retainer, together with the second retainer, be arranged between ring face and packing ring, described outer cover connects lasso and packing ring.
Described needle roller, lasso internal diameter and the first retainer form not the needle bearing with inner ring.
Described ring face, the second retainer, steel ball and packing ring form thrust ball bearing.
Described lasso adopts the thick-walled structure design.
The Dimension Measurement tolerance of described bearing adopts highi degree of accuracy.
The working surface roughness of described bearing adopts the highi degree of accuracy grade.
Described steel ball adopts the highi degree of accuracy grade, to reduce the bearing noise
This composite structure bearing can bear radially, axially or radially with axial joint load.
Compared with prior art, the utlity model has following advantage:
1, this composite structure bearing can bear radially, axially or radially with axial joint load.
2, have that noise reduction is little, long service life, compact structure, reliability are high, applied range, wide adaptability, be easy to install, for metallurgical equipment, also can be used for the industries such as screw rod freezer, airfloat equipment, counterflow cooling tower, aerator, former water-treating equipment, reach domestic and international advanced level.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
