Description

High-performance roller bearing

Technical field

This utility model relates to roller bearing technical field, especially a kind of high-performance roller bearing.

Background technology

Along with the development of industry, roller bearing is widely used in various industry field.Roller bearing is applicable to Under the operating mode of heavy load and impact load, different design organizations is very big on bearing load carrying capacity impact, current bearing inner race And there is between outer ring gap, dust is easy to enter into inside from gap, adheres to, with on rolling element, produce the biggest making an uproar Sound, and affect the service life of bearing.

Utility model content

The technical problems to be solved in the utility model is: in order to solve have between prior art middle (center) bearing inner ring and outer ring Gap, dust is easy to enter into inside from gap, adheres to and on rolling element, the problem producing the biggest noise, existing offer A kind of high-performance roller bearing.

This utility model solves its technical problem and be the technical scheme is that a kind of high-performance roller bearing, including interior Circle and outer ring, be provided with rolling chamber between described inner ring and outer ring, described rolling intracavity is provided with rolling element, and described inner ring is with outer Being formed between circle and roll the gap that chamber connects, the both sides being positioned at described rolling element in described gap are respectively arranged with a circle Ring, the inner side of described annulus contacts with described inner ring, and the outside of described annulus contacts with described outer ring, and the both sides of described inner ring are equal Being provided with a fixed plate, it is spacing that described fixed plate is provided with first matched with described annulus near the side of described inner ring Plate, the both sides that the outer circumference surface of described inner ring is positioned at described rolling element are provided with second limiting plate, described rolling element The annulus of both sides is respectively positioned between the first limiting plate of its side, place and the second limiting plate, two described annulus, inner ring and outer ring Between formed shoe cream room.

Arranging two annulus in gap between outer ring and inner ring in this programme, the inner side of annulus contacts with inner ring, circle The outside of ring contacts with outer ring so that two annulus, form shoe cream room between inner ring and outer ring, adds lubrication in shoe cream room Oil so that rolling element and annulus are sufficiently lubricated, reduces friction, and on the one hand two annulus can enter oil storage with blocks dust Chamber, the lubricating oil interior to it pollutes, and on the other hand annulus can improve the bearing capacity of bearing, this outer stationary plates greatly Can stop a part of dust, wherein the first limiting plate and the second limiting plate are for axially positioning rolling element.

For the ease of oil addition in shoe cream room, further, the lateral surface of described outer ring is provided with oil filler point, Described oil filler point connects with described shoe cream room, and described oil filler point is provided with plug.

Preferably, it is connected by screw is fixing between described fixed plate with described inner ring.

The beneficial effects of the utility model are: high-performance roller bearing of the present utility model is by arranging circle in gap Ring so that two annulus, form shoe cream room between inner ring and outer ring, shoe cream room is used for storing lubricating oil so that rolling element and circle Ring is sufficiently lubricated, and reduces rolling element and the pivoting friction resistance of annulus, and two annulus the most effectively prevent dust to enter Entering shoe cream room, annulus greatly improves the bearing capacity of bearing simultaneously.

Detailed description of the invention

Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.

Embodiment 1

As illustrated in fig. 1 and 2, a kind of high-performance roller bearing, including inner ring 1 and outer ring 2, between described inner ring 1 and outer ring 2 Being provided with rolling chamber, described rolling intracavity is provided with rolling element 3, is formed and rolls chamber and connect between described inner ring 1 and outer ring 2 Gap 4, the both sides being positioned at described rolling element 3 in described gap 4 are respectively arranged with an annulus 5, and the cross section of annulus 5 is circle Shape, the inner side of described annulus 5 contacts with described inner ring 1, and the outside of described annulus 5 contacts with described outer ring 2, described inner ring 1 Both sides are provided with a fixed plate 6, and described fixed plate 6 is provided with near the side of described inner ring 1 and matches with described annulus 5 The first limiting plate 7, the outer circumference surface of described inner ring 1 is positioned at the both sides of described rolling element 3 be provided with one second spacing Plate 8, the annulus 5 of described rolling element 3 both sides is respectively positioned between the first limiting plate 7 and second limiting plate 8 of its side, place, two institutes State formation shoe cream room 9 between annulus 5, inner ring 1 and outer ring 2, the first limiting plate 7 and the second limiting plate 8 for by fixed for rolling element 3 Position, the first limiting plate 7 and the second limiting plate 8 are all in circular arc, and fixed plate 6 is ringwise.

Being provided with oil filler point 10 on the lateral surface of described outer ring 2, described oil filler point 10 connects with described shoe cream room 9, described Plug 11 is installed on oil filler point 10, plug 11 is taken away, lubricating oil can be injected in shoe cream room 9.

It is connected by screw 12 is fixing between described fixed plate 6 with described inner ring 1.

Above-mentioned high-performance roller bearing arranges two annulus 5 in the gap 4 between outer ring 2 and inner ring 1, annulus 5 Inner side contacts with inner ring 1, and the outside of annulus 5 contacts with outer ring 2 so that two annulus 5, formation oil storages between inner ring 1 and outer ring 2 Chamber 9, adds lubricating oil beforehand through oil filler point 10 so that rolling element 3 and annulus 5 are sufficiently lubricated, and subtract in shoe cream room 9 Few friction, two annulus 5 one aspects blocks dust can enter shoe cream room 9, and the lubricating oil interior to it pollutes, on the other hand Annulus 5 can improve the bearing capacity of bearing greatly, and this outer stationary plates 6 can stop a part of dust.

Above-mentioned is enlightenment according to desirable embodiment of the present utility model, by above-mentioned description, relevant staff Various change and amendment can be carried out completely in the range of without departing from this utility model technological thought.This practicality The content that novel technical scope is not limited in description, it is necessary to determine that it is technical according to right Scope.
