Abstract
The utility model discloses a kind of joint shaft bearing of flanged outer ring, comprise an inner ring and a flange outer ring, flange outer ring comprises outer ring and is positioned at the flange plate of periphery, described outer ring, flange plate and outer ring one-body molded; The curved structure of inwall of flange outer ring, inner ring is placed in flange outer ring, and the inwall of the outer wall of inner ring and flange outer ring closely cooperates, and the internal diameter of inner ring is 4-40mm, and the external diameter of outer ring is 12-62mm, and the radius of curvature of interior ring outer wall is 8-53mm.Compared with prior art, joint shaft bearing of the present utility model not only can realize axially locating, but also can realize circumference location; Meanwhile, this joint shaft bearing easy accessibility and can reduce assembling magnitude of interference on the impact of bearing flexibility.
Description
Technical field
The utility model relates to a kind of joint shaft bearing, the joint shaft bearing of a kind of flanged outer ring of special design.
Background technique
Joint shaft bearing is assembled by inside and outside circle.When bearing uses, bearing requires axially locating and circumference location after loading housing bore.There is the method for many location in existing techniques in realizing, as elastic conjunction, band locking groove outer ring, band stop flange outer ring, or increase other accessory such as end cap, ring washer.But there is shortcomings and deficiency in localization method of the prior art.
First, these methods make bearing realize axially locating in housing bore, do not have reliable circumferential positioning action, although namely bearing is not easily deviate from housing bore, but still may occur the skidding of outer ring in housing bore.Especially to this class sliding bearing of joint shaft bearing, the friction torque of bearing is large compared with rolling bearing.Secondly, although elastic conjunction method is relatively simple, in addition to the above drawbacks, also add mating face requirement on machining accuracy and not easily exchange, magnitude of interference has the original play of bearing and flexibility can not accurate Calculation and unmanageable impact.Finally, other method complex structure, take up room.So, for not only meeting axially locating but also can meet that the joint bearing type of circumference location needs badly.
Summary of the invention
The purpose of this utility model, providing a kind of joint shaft bearing of flanged outer ring exactly, not only can meet the axially locating of bearing in order to solve the problem, but also can meet the circumference location of bearing.
The purpose of this utility model is achieved in that
A joint shaft bearing for flanged outer ring, comprises an inner ring and a flange outer ring, and described flange outer ring comprises outer ring and is positioned at the flange plate of periphery, described outer ring, described flange plate and outer ring one-body molded; The curved structure of inwall of described flange outer ring, described inner ring is placed in described flange outer ring, and the inwall of the outer wall of described inner ring and described flange outer ring closely cooperates, the internal diameter of described inner ring is 4-40mm, the external diameter of described outer ring is 12-62mm, and the radius of curvature of described interior ring outer wall is 8-53mm.
The joint shaft bearing of above-mentioned a kind of flanged outer ring, wherein, described inner ring and flange outer ring adopt stainless steel or high-carbon-chromium bearing steel to make, and the surface of contact of described inner ring and flanged outer ring are coated with hard chromium layers or phosphating coating.
The joint shaft bearing of above-mentioned a kind of flanged outer ring, wherein, described flange plate is provided with 8 circumferentially uniform counterbores.
Compared with prior art, the utility model is transformed on the basis of traditional joint shaft bearing, the outer ring of joint shaft bearing is transformed into the flanged (FLGD) outer ring of integral type.This transformation can realize axially locating and circumference location after joint shaft bearing loads housing bore, prevents outer ring from skidding in housing bore.And the easy accessibility of this bearing and can reduce assembling magnitude of interference on the impact of bearing flexibility.Meanwhile, the inner ring of bearing and the surface of contact of flanged outer ring are coated with hard chromium layers or phosphating coating, the life-span of bearing can be increased.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, there is shown a kind of joint shaft bearing of flanged outer ring, comprise inner ring 1 and a flange outer ring 2, inner ring 1 and flange outer ring 2 adopt stainless steel or high-carbon-chromium bearing steel to make, and the surface of contact of inner ring 1 and flanged outer ring 2 are coated with hard chromium layers or phosphating coating; Flange outer ring 2 comprises outer ring 21 and is positioned at the flange plate 22 of periphery, outer ring, flange plate 22 and outer ring 21 one-body molded, flange plate 22 is provided with 8 circumferentially uniform counterbores 3; The curved structure of inwall of flange outer ring 2, inner ring 1 is placed in flange outer ring 2, and the inwall of the outer wall of inner ring 1 and flange outer ring 2 closely cooperates, and the internal diameter of inner ring 1 is 4-40mm, and the external diameter of outer ring 21 is 12-62mm, and the radius of curvature of inner ring 1 outer wall is 8-53mm.
In the utility model, because joint shaft bearing has been designed to flange outer ring 2, flange plate 22 realizes axially locating after making flange outer ring 2 load housing bore, flange outer ring 2 and housing are fastenedly connected by the counterbore 3 on flange plate by screw, realize circumference location, thus prevent flange outer ring 2 from skidding in housing bore.Especially when inner ring 1 is fixed, during the lasso of flange outer ring 2 as bearing rotary or swing, this stationary positioned mode is more reliable.Above structure not only makes bearing dismantling convenient, but also can reduce assembling magnitude of interference to the impact of bearing flexibility.Meanwhile, the inner ring 1 of bearing and the surface of contact of flanged outer ring 2 are coated with hard chromium layers or phosphating coating, this makes the life-span of bearing increase.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technological schemes also should belong to category of the present utility model, should be limited by each claim.
