Description
Technical field
The present invention relates to a kind of shaft connecting bearings, particularly a kind of new construction shaft connecting bearing.
Background technology
At present, auto pump is because the bearing used in cost declining needs is mostly using shaft connecting bearing, this bearing arrangement
On be equivalent to and incorporate two monomer bearings, the structure for making bearing is more compact, and assembling is more convenient.But due to shaft connecting bearing mistake
In compact, inner space is too small so that the roller of shaft connecting bearing is to keep axial by bearing outer ring and dustband in the axial direction
Positioning, when bearing bears certain axial load, due to roller axial float can to dustband generate an axial direction
Pressure can deform dustband, and so as to cause the seal failure of dustband, impurity enters Bearing inner, and bearing is caused to use the longevity
Life is reduced.
The content of the invention
The technical problem to be solved by the present invention is to：A kind of new construction shaft connecting bearing on auto pump is provided, can be prevented
Only so that dustband deformation due to the axial float of roller.
Solving the technical solution of above-mentioned technical problem is：A kind of new construction shaft connecting bearing, including jackshaft, bearing outer ring,
Roller, roller rolling retainer and dustband, bearing outer ring are placed on jackshaft, roller by roller rolling retainer be arranged at jackshaft and
In space between bearing outer ring, roller is placed in roller rolling retainer, and dustband is arranged between jackshaft and bearing outer ring simultaneously
Play the role of sealing, it is characterised in that：Flange collar is equipped with close to the roller rolling retainer of dustband, is set on the bearing outer ring
Have with the corresponding groove of flange collar, when flange collar is located in groove, have larger stabilization between roller rolling retainer and dustband
Gap.
The present invention further technical solution be：Gap between the roller rolling retainer and dustband is located at more than flange collar
Existing gap between flange collar and groove when in groove.
Due to the adoption of the above technical scheme, a kind of new construction shaft connecting bearing of the present invention, has the advantages that：
In order to improve the service life of bearing, the present invention provides a kind of shaft connecting bearings of new structure, can prevent because of bearing
The deformation of dustband caused by the axial float of the bearing of roller.The present invention is raised plus one on roller rolling retainer
Circle, while set on bearing outer ring that there are one corresponding grooves.Roller, on request again will dress on roller rolling retainer during assembling
The roller rolling retainer of good roller gently riveting into the flange collar on roller rolling retainer between jackshaft and bearing outer ring, is made just to be stuck in bearing
In groove on outer ring, achieve the purpose that prevent retainer and roller axial float.When shaft connecting bearing in the present invention works, axis
Holding the power of the axial float suffered by roller can be such that power acts on the groove of bearing outer ring by roller rolling retainer, it is therefore prevented that right
Dustband applies axial pressure, ensure that dustband is not forced deformation, so as to improve the reliability of the sealing of dustband.
Improve the cleannes and service life of the inside of shaft connecting bearing.
In the following, with reference to Figure of description and specific embodiment to a kind of technical characteristic of new construction shaft connecting bearing of the present invention
It is further described.
Description of the drawings
Fig. 1：A kind of structure diagram of new construction shaft connecting bearing.
Fig. 2：Installation relation schematic diagram between roller, dustband and roller rolling retainer.
Fig. 2 is the enlarged diagram of A in Fig. 1.
In above-mentioned attached drawing, each label declaration is as follows：
1- jackshafts, 2- dustbands, 3- roller rolling retainers, the groove on 4- bearing outer rings, the flange collar on 5- roller rolling retainers, 6-
Bearing outer ring, 7- rollers, the roller rolling retainer supporting-point of 8- bearing outer rings.
Specific embodiment
A kind of new construction shaft connecting bearing, including jackshaft, bearing outer ring, roller, roller rolling retainer and dustband, outside bearing
In on jackshaft, roller is arranged at by roller rolling retainer in the space between jackshaft and bearing outer ring snare, and roller is set
In in roller rolling retainer.Dustband is arranged between jackshaft and bearing outer ring, dustband both ends respectively with jackshaft and bearing
Outer ring forms sealing structure, plays the role of sealing, to prevent foreign matter from entering the space between jackshaft and bearing outer ring.
Roller rolling retainer be equipped with flange collar, the bearing outer ring be equipped with the corresponding groove of flange collar, when flange collar is located in groove
When roller rolling retainer and dustband between have certain gap, be stuck in groove by flange collar so that roller rolling retainer can only
In a small range axial float, dustband will not be collided.When the gap between roller rolling retainer and dustband is more than flange collar position
The existing gap between flange collar and groove when in groove can prevent flange collar roller rolling retainer when groove carries out axial float from touching
Bump against dustband.
The operation principle of existing shaft connecting bearing：Usually, the erection sequence of shaft connecting bearing roller part is first to fill roller
It in roller rolling retainer, places into the space between bearing outer ring and jackshaft, utilizes the roller rolling retainer branch of bearing outer ring
Point location is held, is loaded on dustband.Therefore roller rolling retainer and roller can be between dustband and roller rolling retainer supporting-points
Carry out the movement of axial direction.During work, due between roller and jackshaft can there are a small gap (clearance), therefore work as
Jackshaft bear simultaneously axial direction power and rotation power when, jackshaft can be there are one small circumference up and down
It swings, roller and roller rolling retainer is made to generate displacement in the axial direction, when retainer encounters dustband, dustband can be produced
A raw pressure, deforms the rubber parts on dustband, and gap, and then seal failure occurs in the seal groove between jackshaft,
Foreign matter then enters inside shaft connecting bearing, causes internal lubrication oil failure, and bearing life shortens.
The present invention is improved on the basis of existing shaft connecting bearing, increases by one in roller rolling retainer (3) fixed setting
Flange collar (5), and set on bearing outer ring (6) one and flange collar (5) corresponding groove (4), flange collar during assembled shaft connecting shaft
(5) and groove (4) just can block roller rolling retainer (3) with merging, make roller rolling retainer (3) and roller (7) in axial fortune
It is dynamic to be limited in certain scope（It is limited in flange collar (5) and the interstice coverage of groove (4)）.Due to dustband (2)
Retain certain gap between roller rolling retainer (3), and the gap between roller rolling retainer (3) and dustband (2) is more than convex
Circle (5) be located at groove (4) it is interior when flange collar (5) and groove (4) between existing gap.Therefore when roller rolling retainer (3) and roller (7)
During generation axial displacement, it just can effectively prevent roller rolling retainer (4) and roller (8) encounter dustband (2), avoid dustband
(2) deformed due to axially loaded and cause seal failure.So as to maintain the cleannes inside shaft connecting bearing, shaft connecting bearing is improved
Service life.
