Abstract
The utility model discloses a rolling bearing with a split type outer ring, which has the advantage of high load bearing capacity. The rolling bearing comprises an inner ring and an outer ring, wherein a plurality of rolling posts are arranged between the inner ring and the outer ring. The circumferential direction of the outer side of the inner ring and the circumferential direction of the inner side of the outer ring are provided with grooves which are corresponding, and the axial lengths of the two grooves are equal. The length of each rolling post is in accordance with the axial length of each groove, and both radial sides of each rolling post are respectively arranged in the two grooves. The outer ring is in a split type, and the split type outer ring is composed of a main body of the outer ring and a sheet-shaped retainer ring, wherein one axial side of the main body of the outer ring is used for forming a radial inner bulge edge of the groove wall, and the sheet-shaped retainer ring is attached to the other axial side of the main body of the outer ring in the state of assembly. The diameter of an outer circle of the sheet-shaped retainer ring is equal to the diameter of the main body of the outer ring, and the diameter of an inner circle of the sheet-shaped retainer ring is equal to the diameter of an inner circle of the radial inner bulge edge at one axial side of the main body of the outer ring. Thereby, the inner edge of the sheet-shaped retainer ring is used as the other groove wall of the outer ring. The rolling bearing has the advantages of strong radial loading bearing capacity, strong axial loading bearing capacity and long service life.
Description
(1) technical field
The utility model relates to a kind of bearing.Specifically, be a kind of outer ring be split type, have a roller bearing than high bearing capacity.
(2) background technique
At present, used roller bearing on the various machinery, all by inner ring, outer ring and some roll to lean on form.Also be provided with annular retainer between inside and outside circle wherein, plurality of rollers is by means of this annular retainer and is set in qually spaced between the inside and outside circle.Owing to be provided with annular retainer between the inside and outside circle of this bearing, occupied between the Internal and external cycle than large space, the radial dimension of roller and axial dimension are all less under the fixed situation of bearing specification, make that the radially bearing capacity and the axial carrying capacity of bearing are relatively poor.Owing to being by annular retainer, plurality of rollers is set in qually spaced between the inside and outside circle again, make roller leave the gap each other, this gap has also occupied the certain space between the inside and outside circle, makes used roller negligible amounts, so also can have influence on the bearing capacity of bearing.Therefore, the working life of this bearing is not long.
(3) model utility content
The technical problems to be solved in the utility model provides a kind of roller bearing.The radially bearing capacity of this roller bearing and axial carrying capacity are strong, long service life.
For addressing the above problem, the utility model is taked following technical solution:
Roller bearing of the present utility model contains inner ring and outer ring, between inside and outside circle plurality of rollers is arranged.The external circumferential of inner ring and the inner circumferential of outer ring are fluted, and this two groove is corresponding and axial length equal.The axial length of the length of said roller and two grooves adapts, and it radially places respectively in two grooves both sides.Its structural feature is that said outer ring is split type, and this split type outer ring is made up of outer ring body and sheet back-up ring.Wherein, an axial side of outer ring body is useful on the radially inner raised edge that forms cell wall.Said sheet back-up ring leans against the axial opposite side of outer ring body under assembling condition, its outside diameter equates with the outer ring body, circular diameter equates with the interior circular diameter of outer ring body shaft to the radially inner raised edge of a side in it, thereby makes sheet back-up ring inside edge by another cell wall as the outer ring.
Plurality of rollers circumferentially is the arrangement of contact shape along the groove on the inside and outside circle and forms.
Adopt such scheme, have the following advantages:
Because roller bearing of the present utility model, its outer ring is split type, and this split type outer ring is made up of outer ring body and sheet back-up ring.An axial side of outer ring body is useful on the radially inner raised edge that forms cell wall, the sheet back-up ring leans against the axial opposite side of outer ring body under assembling condition, its outside diameter equates with the outer ring body, circular diameter equates with the interior circular diameter of outer ring body shaft to the radially inner raised edge of a side in it, thereby makes sheet back-up ring inside edge by another cell wall as the outer ring.Save the annular retainer between the inside and outside circle of traditional roller bearing, saved the space between inside and outside circle.Under the fixed situation of bearing specification, can increase the size of roller, improve the radially bearing capacity and the axial carrying capacity of bearing.Owing to saved annular retainer, plurality of rollers can be arranged along the contact shape that circumferentially is between the inside and outside circle again, and making does not have the gap between roller and the roller, has increased the quantity of roller, thereby has further improved the bearing capacity of bearing.Therefore, roller bearing of the present utility model is longer working life.
(4) description of drawings
Accompanying drawing is a roller bearing structure schematic representation of the present utility model.
(5) embodiment
As shown in drawings, roller bearing of the present utility model contains inner ring 1 and outer ring, and plurality of rollers 3 is arranged between inner ring 1 and the outer ring.Wherein, the excircle of inner ring 1 is to being processed with groove, and the radial section of this groove is a rectangle.Said outer ring is split type, and this split type outer ring is made up of outer ring body 2 and sheet back-up ring 4.Outer ring body 2 axial sides wherein are processed with the radially inner raised edge 5 that is used to form cell wall.Said sheet back-up ring 4 is free shape and leans against outer ring body 2 and do not have a radially side of inner raised edge under assembling condition, its outside diameter equates with the outside diameter of outer ring body 2, circular diameter equates with the interior circular diameter of the radially inner raised edge 5 of outer ring body 2 axial sides in it, its thickness equates with radially inner raised edge 5 thickness of outer ring body 2 axial sides, thereby makes the inside edge of sheet back-up ring 4 be used as another cell wall of outer ring body 2.Spacing between the groove bottom land inner side surface on the diameter of said roller 3 and inner ring 1 and the outer ring adapts, and the groove axial length on its length and inner ring 1 and the outer ring adapts.After making that plurality of rollers 3 is the contact shape and arranges along the circumferencial direction between the inside and outside circle, their radially both sides are stuck in respectively in the groove on inner ring 1 and the outer ring.
Claims (2)
1. roller bearing comprises inner ring (1) and outer ring, and plurality of rollers (3) is arranged between inner ring (1) and outer ring; The external circumferential of inner ring (1) and the inner circumferential of outer ring are fluted, and this two groove is corresponding and axial length equal; The length of said roller (3) and the axial length of two grooves adapt, and it radially places respectively in two grooves both sides; It is characterized in that said outer ring is split type, this split type outer ring is made up of outer ring body (2) and sheet back-up ring (4); Wherein, an axial side of outer ring body (2) is useful on the radially inner raised edge (5) that forms cell wall; Said sheet back-up ring (4) leans against the axial opposite side of outer ring body (2) under assembling condition, its outside diameter equates with outer ring body (2), circular diameter equates with the interior circular diameter of the radially inner raised edge (5) of the axial side of outer ring body (2) in it, thereby makes sheet back-up ring (4) inside edge by another cell wall as the outer ring.
