Abstract
The utility model relates to the field of bearings, in particular to a self-lubricating bearing, which comprises an inner ring, an outer ring, a retainer, balls, a steel ring and nuts. The balls are arranged between the inner ring and the outer ring and positioned inside holes of the retainer. The outer ring formed by two semi-circles, two ends of each semi-circle are provided with zigzag mating surface grooves which are connected together, and the nuts are connected with the outer ring through the steel ring positioned in a groove which is arranged on the outer ring. The self-lubricating bearing is convenient to install.
Description
Technical field
The utility model relates to field of bearings, concretely, relates to a kind of self oiling bearing.
Background technique
Existing bearing adopts metallic material to make mostly, and bearing is generally by inner ring, the outer ring, and retainer, rolling element constitutes; But bearing will rely on oiling agent to keep the lubricated of rolling element and inner ring and outer ring in use, otherwise will damage bearing; Bearing is according to complex process; Bearing maintenance overhaul difficulty.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of self oiling bearing, and its inner ring, outer ring and retainer all are to meet material by carbon fiber to make, and rolling element is made by stupalith.
The utility model is made of inner ring, outer ring, retainer, ball, steel ring, nut; Be ball between inner ring and the outer ring, ball is in the pocket hole of retainer.The outer ring is that two semicircle circles constitute, and each semicircle circle two has zigzag emboss pit, and the zigzag fashion emboss pit of two semicircle circles connects, and is fluted on the outer ring, and steel ring is arranged in the groove, and nut passed through steel ring and connects the outer ring.
Advantage of the present utility model: easy for installation, the outer ring is to adopt the split-type structural design, and is easy to installation and maintenance.Inner ring, outer ring and retainer all are to be made by carbon fiber composite, the carbon fiber composite main component is a carbon, rolling element and inner ring, outer ring and retainer friction are to have self-lubricating effect, the stupalith rolling element has the following advantages: (1) is not because pottery almost is afraid of corrosion, so ceramic rolling bearing is suitable for being covered with operation under the mal-condition of Korrosionsmedium.(2) because the density of ceramic rolling bead is lower than steel, and weight is more light, the centrifugal action to the outer ring when therefore rotating can reduce by 40%, and then prolong working life greatly.(3) the pottery influence of being expanded with heat and contract with cold is littler than steel, thereby in the gap one of bearing regularly, can allow bearing to work in the comparatively violent environment of difference variation.(4) because the modular ratio steel height of pottery is not yielding when stressed, therefore helps improving operating rate, and reach higher precision.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Embodiment
Reference character shown in Figure 2 is as follows: outer ring 1, steel ring 2, nut 3, retainer 4, ball 5, inner ring 6.
Be ball 5 between inner ring 6 and the outer ring 1, ball 5 is in the pocket hole of retainer 4.Outer ring 1 is that two semicircle circles constitute, and each semicircle circle two has zigzag emboss pit, and the zigzag fashion emboss pit of two semicircle circles connects, and is fluted on the outer ring 1, and steel ring 2 is arranged in the groove, and nut 3 connects outer ring 1 through steel ring 2.
