Abstract
The invention discloses a high-bearing-capacity roller bearing. The roller bearing comprises an outer ring, an inner ring and a plurality of cylindrical rollers arranged between the outer ring and the inner ring by virtue of check rings, wherein an upper dustproof cover and a lower dustproof cover are respectively arranged at two ends of the inner side of the outer ring, and the check rings and the inner ring are arranged inside the outer ring by virtue of the upper dustproof cover and the lower dustproof cover.
Description
Technical field
The present invention relates to a kind of bearing, relate in particular to a kind of high-mechanic roller bearing.
Background technique
The bearing of production and application is all the deep groove ball bearing of dual face seals at present, owing to being a contact between rolling element and lasso, so carrying can be that power is little, often crushed, crowded bad, and use occasion does not allow to change midway.Therefore need to use the roller bearing that bearing capacity is large instead, because of the retainer structure of band, owing to managing the existence of frame, reduce on the one hand the quantity of roller, in needs high-bearing capacity, this bearing cannot meet produces the high requirement of bearing capacity.On the other hand, retainer exists cannot fill seal ring, and in dedicated process, refuel(l)ing is lubricated, also cannot nourish.
Summary of the invention
Technical problem to be solved by this invention is: the high-mechanic roller bearing that a kind of bearing capacity is high is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: high-mechanic roller bearing, comprise: outer ring, inner ring and be arranged on outer ring and inner ring between some cylindrical rollers, described some cylindrical rollers are arranged between outer ring and inner ring by back-up ring, on the two ends, inner side of described outer ring, be respectively arranged with dust cover and lower dust cover, described back-up ring and inner ring are arranged on inner side, outer ring by upper dust cover and lower dust cover.
In order to solve the problems of the technologies described above better, the further technological scheme that the present invention adopts is: be provided with oil hole at described inner ring middle part.
Advantage of the present invention is: above-mentioned high-mechanic roller bearing, overcome the low deficiency of existing bearing capacity, fill roller, cancel retainer, increase roller number, improve the bearing capacity of bearing, roller adopts the reinforced roller lengthening, increase the surface of contact in roller and inside and outside scroll road, thereby improve the bearing capacity of bearing, Internal and external cycle is separable, and can exchange, be convenient to installation and removal, roller and the friction of Internal and external cycle raceway are little, be applicable to running up, on inner ring, be with an oil hole, the oil hole matching with it on axle joins, at any time can oil injecting lubricating, thereby improve the working life of bearing.
Brief description of the drawings
Fig. 1 is the structural representation of high-mechanic roller bearing of the present invention.
In figure: 1, outer ring, 2, inner ring, 3, cylindrical roller, 4, back-up ring, 5, upper dust cover, 6, lower dust cover, 7, oil hole.
Embodiment
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, high-mechanic roller bearing, comprise: outer ring 1, inner ring 2 and be arranged on outer ring 1 and inner ring 2 between some cylindrical rollers 3, described some cylindrical rollers 3 are arranged between outer ring 1 and inner ring 2 by back-up ring 4, on the two ends, inner side of described outer ring 1, be respectively arranged with dust cover 5 and lower dust cover 6, described back-up ring 4 and inner ring 2 are arranged on 1 inner side, outer ring by upper dust cover 5 and lower dust cover 6.Be provided with oil hole 7 at described inner ring 2 middle parts.Use above-mentioned high-mechanic roller bearing to be contained on running shaft, on running shaft, be provided with one with oil hole 7 tank filler sleeve that cooperatively interacts, the tank filler sleeve of lubricant oil from running shaft enters the surface that then oil hole 7 enter the cylindrical roller 3 of rotation it is lubricated.
Above-mentioned high-mechanic roller bearing, overcome the low deficiency of existing bearing capacity, fill roller, cancel retainer, increase roller number, improve the bearing capacity of bearing, roller adopts the reinforced roller lengthening, increase the surface of contact in roller and inside and outside scroll road, thereby improve the bearing capacity of bearing, Internal and external cycle is separable, and can exchange, be convenient to installation and removal, roller and the friction of Internal and external cycle raceway are little, be applicable to running up, on inner ring, be with an oil hole, the oil hole matching with it on axle joins, at any time can oil injecting lubricating, thereby improve the working life of bearing.
Claims (2)
1. high-mechanic roller bearing, it is characterized in that: comprising: outer ring (1), inner ring (2) and be arranged on outer ring (1) and inner ring (2) between some cylindrical rollers (3), described some cylindrical rollers (3) are arranged between outer ring (1) and inner ring (2) by back-up ring (4), on the two ends, inner side of described outer ring (1), be respectively arranged with dust cover (5) and lower dust cover (6), described back-up ring (4) and inner ring (2) are arranged on inner side, outer ring (1) by upper dust cover (5) and lower dust cover (6).
