Abstract
The invention relates to a rolling needle bearing. The rolling needle bearing is a combined bearing and comprises a ferrule, a rolling needle, a first holding frame, a second holding frame, steel balls, a gasket and an outer cover, wherein after the rolling needle is mounted on the first holding frame, the rolling needle and the first holding frame are mounted along the inner diameter in the ferrule, after the steel balls are mounted on the second holding frame, the steel balls and the second holding frame are mounted between the end face of the ferrule and the gasket, and the outer cover is connected with the ferrule and the gasket. Compared with the prior art, the rolling needle bearing has the advantages of low noise, long service life, compact structure, high reliability, wide application rang and adaptability, easiness in mounting and the like.
Description
Technical field
The present invention relates to a kind of bearing, especially relate 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 the space to bearing intensity, installation, simple, noise requirement, life requirements, carrying etc. be installed also have corresponding requirement.And existing bearing can only singlely be installed, alignment error, installing space are also large, and combination property is not strong.
Summary of the invention
Object of the present invention 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.
Object of the present invention 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, be arranged on together with the first retainer in the internal diameter of lasso, after described steel ball is arranged on the second retainer, be arranged between ring face and packing ring together with the second retainer, described outer cover connects lasso and packing ring.
Described needle roller, lasso internal diameter and the not needle bearing with inner ring of the first retainer composition.
Described ring face, the second retainer, steel ball and packing ring composition thrust ball bearing.
Described lasso adopts thick-walled structure design.
The Dimension Measurement tolerance of described bearing adopts highi degree of accuracy.
The working surface roughness of described bearing adopts highi degree of accuracy grade.
Described steel ball adopts highi degree of accuracy grade, to reduce bearing noise
This composite structure bearing can bear radially, axially or radially with axial joint load.
Compared with prior art, the present invention has the following advantages:
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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of needle bearing, this bearing is combined bearing, described needle bearing comprises lasso 1, needle roller 2, the first retainer 3, the second retainer 6, steel ball 4, packing ring 5 and outer cover 7, after described needle roller 2 is arranged on the first retainer 3, be arranged in the internal diameter of lasso 1 together with the first retainer 3, after described steel ball 4 is arranged on the second retainer 6, be arranged between lasso 1 end face and packing ring 5 together with the second retainer 6, described outer cover 7 connects lasso 1 and packing ring 5.
Described needle roller 2, lasso internal diameter and the first retainer 3 form the needle bearing of not being with inner ring.Described ring face, the second retainer 6, steel ball 4 and packing ring 5 form thrust ball bearing.
The Dimension Measurement tolerance of bearing adopts highi degree of accuracy grade; Lasso is provided with thick-walled structure design, and adopts hard Vehicle Processing technique; Bearing working surface roughness adopts highi degree of accuracy grade; Steel ball adopts highi degree of accuracy grade, to reduce bearing noise; This composite structure bearing can bear radially, axially or radially with axial joint load.The present invention has 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 top standard.
