Abstract
The invention relates to a new sealed double-row cylindrical roller bearing, which is applied to a railway locomotive axle box and belongs to the field of metallurgy. The bearing with the primary structure for the high-power railway locomotive axle box has low bearing capacity, fussy installation and use and short service life, and does not meet the requirement of a working environment. The sealed double-row cylindrical roller bearing comprises an outer ring, a seal cover, a retainer, a cylindrical roller and an inner ring; and meanwhile, the bearing adopts an ECP structural design which is favorable for improving the bearing capacity of the bearing, improving the reliability and prolonging service life of the bearing.
Description
Technical field
The invention belongs to technical field of bearings, particularly a kind of Biserial cylindrical roller bearing that is applied to railway locomotive axle box.
Background technique
The high-power railway locomotive axle box that the railway motion speed is 120 kilometers/hour with the original structure of bearing is: two cover open type single row roller bearing pairings are used, and retainer is a copper cage.This airframe bearing bearing capacity is low, it is loaded down with trivial details to install and use, and occurs the phenomenon that retainer falls the copper end in use, causes the bearing temperature rise height, the early fatigue phenomenon occurs, do not meet the operating mode needs.
Summary of the invention
For overcoming the above problems, the objective of the invention is: a kind of sealed double-row cylindrical roller bearing of railway special use is provided, improves bearing capacity, prolong bearing working life.
Technological scheme of the present invention is: the sealed double-row cylindrical roller bearing of railway special use, comprise outer ring 1, seal closure 2, retainer 3, cylindrical roller 4 and inner ring 5, and cylindrical roller 4 adopts the logarithmic curve form, and inner retaining side adopts inclined flange; Bearing adopts the ECP structural design: roller adopts the logarithmic curve form, and inner retaining side adopts inclined flange, and retainer 3 adopts engineering plastics cage, has stopped copper cage copper foam dropping phenomenon, has reduced bearing temperature rise.
The invention has the beneficial effects as follows: this bearing both sides band noncontact seal cover, can effectively prevent dust enter and bearing gets rid of the fat phenomenon, more help forming circulating lubrication in that bearing is inner, keep the good lubrication oil film, help improving bearing capacity, improved the reliability and the life-span of bearing; Roller adopts the logarithmic curve form, improves radially bearing capacity of bearing; Inner retaining side adopts inclined flange, helps forming hydrodynamic lubrication, improves the bearing axial bearing capacity; Retainer adopts engineering plastics cage, has stopped copper cage copper foam dropping phenomenon, has reduced bearing temperature rise, and bearing life improves more than 50%.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is elaborated:
Fig. 1 is a structural representation of the present invention.
Among the figure, 1, the outer ring, 2, seal closure, 3, retainer, 4, cylindrical roller, 5, inner ring.
Embodiment
As shown in Figure 1, the present invention includes outer ring 1, seal closure 2, retainer 3, cylindrical roller 4 and inner ring 5.This bearing both sides band noncontact seal cover 2, can effectively prevent dust enter and bearing gets rid of the fat phenomenon, more help forming circulating lubrication in that bearing is inner, keep the good lubrication oil film, be beneficial to improve bearing capacity, improve bearing reliability and life-span.Bearing adopts the ECP structural design: cylindrical roller 4 adopts the logarithmic curve form, improves radially bearing capacity of bearing; Inner retaining side adopts inclined flange, helps forming hydrodynamic lubrication, improves the bearing axial bearing capacity; Retainer adopts engineering plastics cage, has stopped copper cage copper foam dropping phenomenon, has reduced bearing temperature rise, and bearing life improves more than 50%.
