Abstract
The utility model provides a precisely arranged rolling combined bearing. The precisely arranged rolling combined bearing comprises an inner bearing combined row set, an outer bearing combined row set and a fixed sleeve for mounting the inner bearing combined row set and the outer bearing combined row set, wherein the inner bearing combined row set comprises two inner bearings which are arranged in parallel and an inner separation ring between the inner bearings; the outer bearing combined row set comprises two outer bearings which are arranged in parallel and an outer separation ring between the outer bearings; a gear structure is arranged at the large end of the fixed sleeve. The precisely arranged rolling combined bearing is reasonable in design, simple in structure, easy to machine, convenient to use, high in bearing capability, long in service life and high in economic benefits.
Description
Technical field
The utility model relates to field of bearings, is 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, be engaged in this industry working experience for many years with it, and then develop hard-cover rolling combination bearing, utilize simple design, can make the utility model reach easy to operate, good working effect, effect that economic benefit is high.
Summary of the invention
Technical problem to be solved in the utility model 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 utility model adopts following scheme: hard-cover rolling combination bearing, comprise that inner bearing combines row's group, outer bearing and combine row's group, combine for inner bearing is installed 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 utility model 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.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, hard-cover rolling combination bearing, comprise that inner bearing combines that row organizes 1, outer bearing combine row organize 2, for install inner bearing combine row organize 1 and outer bearing combine row and organize 2 fixed cover 3, described inner bearing is combined row and is organized 1 and comprise two inner bearings 11 that are set up in parallel, be arranged on the cone spacer 12 between inner bearing 11, described outer bearing is combined row and is organized 2 and comprise two outer bearings 21 that are set up in parallel, and is arranged on the outer ring spacer 22 between outer bearing 21, and the large end of described fixed cover 3 is provided with gear structure 4.The first oil spray hole 5 that described inner bearing 11 is consistent with being respectively equipped with central position on cone spacer 12 and the second oil spray hole 6.The 3rd oil spray hole 7 that described outer bearing 21 is consistent with being respectively equipped with central position on outer ring spacer 22 and the 4th oil spray hole 8.On described cone spacer 12 and outer ring spacer 22, be respectively equipped with seal ring 9.
When real work, fixed cover 3 makes inner bearing 11 and outer bearing 21 can carry rightabout active force, the gear mechanism 4 of the large end of fixed cover 3 be beneficial in inner bearing 11 and outer bearing 21 rotation processes because of inner bearing 11 and outer bearing 21 rotating speeds inadequate, utilizing blower fan to blow gear mechanism 4 rotates, to reach the rotating speed needing, the first oil spray hole 5 that inner bearing 11 is consistent with being respectively equipped with central position on cone spacer 12 and the second oil spray hole 6, the 3rd oil spray hole 7 that outer bearing 21 is consistent with being respectively equipped with central position on outer ring spacer 22 and the 4th oil spray hole 8, make lubricant oil can enter smoothly inner bearing 11 and outer bearing 21 inside, reach lubrication, make up deficiency of the prior art, improve economic benefit, reasonable in design, simple in structure, easy processing, easy to use, bearing capacity is strong, long service life, economic benefit is high.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
