Abstract
The utility model belongs to the technical field of outer spherical bearing's technique and specifically relates to an outer spherical bearing of square hole area jackscrew, fit -up gap that has outer lane, inner circle and forms between the two, install a plurality of steel ball through the holder in the fit -up gap, still fill out in the fit -up gap and be equipped with two three lip seal circles that are located the steel ball left and right sides respectively, inner circle length and size is 1.4-1.8 times of outer lane length and size, the hole of inner circle is squarely, adds two locking jackscrews that are used for the tight rotation axis in top on the circumferencial direction of inner circle, and the contained angle that forms between two locking jackscrews is 90 degrees. This outer spherical bearing of square hole area jackscrew, the phenomenon that makes the rotation axis axial float and striking bearing can not appear is guaranteed the bearing and can be worked under normal condition.
Description
Technical field
The utility model relates to the technical field of bearing with spherical outside surface, especially a kind of square hole band jackscrew bearing with spherical outside surface.
Background technique
Bearing with spherical outside surface is mainly used on the jumbo such as farm machinery, mining machinery, Environmental Conditions is more severe, dust, sewage and some corrosive pollutants are once enter Bearing inner, bearing will damage very soon, therefore, these class bearing great majority use three layers of lip seal part, and this type of Sealing sealing effect is relatively good, but adopts the bearing starting torque of this sealing very large.
Usual employing circular hole bearing with spherical outside surface, jackscrew locking mode, in use, jackscrew will soon lose efficacy, and occurred that running shaft rotates in bearing inner race.If adopt square hole bearing with spherical outside surface, the phenomenon that running shaft can be avoided to rotate in brearing bore occurs, square hole due to bearing with spherical outside surface is stamping forming when lasso Vehicle Processing, tolerance of size is larger, often Spielpassung with running shaft, in use there will be running shaft axial float in bearing hole, also there will be the problem that running shaft and brearing bore occur to clash into.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, the utility model provides a kind of square hole band jackscrew bearing with spherical outside surface, both can solve the problem of running shaft axial float in bearing hole, the problem that running shaft and brearing bore occur to clash into can have been solved again.
The utility model solves the technological scheme that its technical problem adopts: a kind of square hole band jackscrew bearing with spherical outside surface, there is outer ring, inner ring and fit up gap formed between the two, by retainer, several steel balls are installed in described fit up gap, also fill out in fit up gap and be provided with three lip sealing rings that two lay respectively at the steel ball left and right sides, described inner ring length dimension is 1.4 ~ 1.8 times of outer ring length dimension; The endoporus of inner ring is square, inner ring circumferentially have additional the locking jackscrew that two are used for holding out against running shaft, between two locking jackscrews, the angle that formed is 90 degree.
For the ease of the rotating shaft of two locking jackscrew locking rotatings, therefore described in technique scheme, the medial axis of two locking jackscrews is perpendicular with the medial axis of endoporus respectively, and the intersection point of the medial axis of two locking jackscrews falls within the medial axis of endoporus.
The beneficial effects of the utility model are: the party's pore area jackscrew bearing with spherical outside surface, the endoporus of inner ring is square, by lengthening the length dimension of inner ring, and the locking jackscrew that two are in 90 degree of angles is circumferentially set at inner ring, two are utilized to lock the rotating shaft of jackscrew locking rotating, make running shaft there will not be axial float and clash into the phenomenon of bearing, ensureing that bearing can work in normal state.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Label in accompanying drawing is: 1, outer ring, 2, inner ring, 21, endoporus, 3, fit up gap, 4, retainer, 5, steel ball, and 6, three lip sealing rings, 7, locking jackscrew.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
See Fig. 1 and Fig. 2, square hole band jackscrew bearing with spherical outside surface of the present utility model, there is outer ring 1, inner ring 2 and fit up gap 3 formed between the two, by retainer 4, several steel balls 5 are installed in fit up gap 3, also fill out in fit up gap 3 and be provided with three lip sealing rings 6 that two lay respectively at steel ball 5 left and right sides, inner ring 2 length dimension is 1.4 ~ 1.8 times of outer ring 1 length dimension, and inner ring 2 length dimension has done and added long process; The endoporus 21 of inner ring 2 is square, and the cross section being assemblied in the running shaft in endoporus 21 is also square.
Inner ring 2 circumferentially to have additional the angle formed between two locking jackscrew 7, two locking jackscrews 7 being used for holding out against running shaft be 90 degree.The medial axis of two locking jackscrews 7 is perpendicular with the medial axis of endoporus 21 respectively, and the intersection point of the medial axis of two locking jackscrews 7 falls within the medial axis of endoporus 21.The party's pore area jackscrew bearing with spherical outside surface utilizes two to lock the rotating shaft of jackscrew 7 locking rotating, makes running shaft there will not be axial float and clashes into the phenomenon of bearing, ensureing that bearing can work in normal state.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
