Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of shield bearing.
Background technique
Bearing rises fixing in mechanical transmission course and reduces the parts of load friction factor, alternatively, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.Existing bearing mainly comprises: bearing outer ring, bearing inner race, retainer and rolling element, described rolling element is arranged between bearing outer ring and bearing inner race by retainer, described bearing outer ring and bearing inner race are respectively equipped with first raceway and the second raceway that can roll for rolling element, in use, owing to there is comparatively wide arc gap between bearing outer ring and bearing inner race both sides, some mechanical dust are easy to enter, aggravation rolling element and the wearing and tearing between bearing outer ring and bearing inner race, cause bearing short for working life, wear rate is high, replacing number of times is frequent, existing bearing lacks lubrication and cooling structure simultaneously, be unfavorable for the high load running of bearing.
Model utility content
Technical problem to be solved in the utility model is: the shield bearing providing a kind of long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: shield bearing, comprise: bearing outer ring, bearing inner race and the bearing hole be arranged in bearing inner race, the inner side of described bearing outer ring is provided with outer raceway, interior raceway is had in the arranged outside of described bearing inner race, roll between described outer raceway and interior raceway and be provided with some rolling elements, be connected by retainer between described rolling element, annular dust cover is respectively arranged with in the both sides of described bearing outer ring and bearing inner race, the upper end of described annular dust cover is fixedly connected with bearing outer ring, annular groove is respectively arranged with in the both sides of described bearing inner race, the lower end of described annular dust cover is slidably arranged in annular groove by ring slider, the lubricating oil inlet be interconnected with outer raceway is provided with in the upper end of described bearing outer ring, annular cooling channel is respectively arranged with in the bearing outer ring of described lubricating oil inlet both sides, the bearing outer ring of described two annular cooling channel upper ends is respectively arranged with the water intake be interconnected with two annular cooling channels, the bearing outer ring of described two annular cooling channel lower ends is respectively arranged with the water outlet be interconnected with two annular cooling channels.
The utility model has the advantages that: above-mentioned shield bearing, by the both sides at bearing outer ring and bearing inner race, the gap that annular dust cover comes between block axis bearing outer-ring and bearing inner race both sides is set respectively, can effectively prevent mechanical dust from entering, reduce rolling element and the wearing and tearing between bearing outer ring and bearing inner race, bearing long service life, wear rate is low, arranging lubricating oil inlet in bearing outer ring inside can add lubricant oil in raceway simultaneously, ensure that rolling element can roll glibly in raceway, arrange annular cooling channel in bearing outer ring inside to lower the temperature to bearing, be conducive to the high load running of bearing.
