Description
Technical field
The present invention relates to field of bearings, be specifically related to hard-cover rolling combination bearing.
Background technique
Rolling bearing is that the sliding friction between the axle of running and axle bed is become to rolling friction, thereby reduce the mechanical component of a kind of precision of frictional loss, be widely used in various machines, generally used aloned all of existing rolling bearing, and the load-carrying ability of single rolling bearing is limited, can not bear the thrust load of several aspects simultaneously, need to design a kind of combined rolling bearing and meet need of work, because the shortcoming of prior art, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, with it, be engaged in this industry working experience for many years, and then develop hard-cover rolling combination bearing, utilize simple design, can make the present invention reach easy to operate, good working effect, the effect that economic benefit is high.
Summary of the invention
Technical problem to be solved by this invention is to provide hard-cover rolling combination bearing, reasonable in design, simple in structure, easy processing, and easy to use, bearing capacity is strong, long service life, economic benefit is high.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: hard-cover rolling combination bearing, comprise that inner bearing combines row's group, outer bearing and combine row's group, for inner bearing is installed, combine the fixed cover that row's group and outer bearing are combined row's group, described inner bearing is combined row's group and is comprised two inner bearings that are set up in parallel, be arranged on the cone spacer between inner bearing, described outer bearing is combined row's group and is comprised two outer bearings that are set up in parallel, be arranged on the outer ring spacer between outer bearing, the large end of described fixed cover is provided with gear structure.
As preferably, the first oil spray hole that described inner bearing is consistent with being respectively equipped with central position on cone spacer and the second oil spray hole.By adopting this set, make lubricant oil can enter smoothly inner bearing and combine row and organize inside and reach lubrication.
As preferably, the 3rd oil spray hole that described outer bearing is consistent with being respectively equipped with central position on outer ring spacer and the 4th oil spray hole.By adopting this set, make lubricant oil can enter smoothly outer bearing and combine row and organize inside and reach lubrication.
As preferably, on described cone spacer and outer ring spacer, be respectively equipped with seal ring.By adopting this set, play good seal action, avoid leakage of oil.
Beneficial effect:
The present invention adopts technique scheme that hard-cover rolling combination bearing is provided, and has made up deficiency of the prior art, has improved economic benefit, reasonable in design, simple in structure, easy processing, and easy to use, bearing capacity is strong, long service life, economic benefit is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
