Abstract
The utility model discloses a bearing, which consists of an outer ring (1), a middle ring (2), an inner ring (3), an outer rolling body (5) and an inner rolling body (4). The middle ring (2) is an eccentric sleeve. The eccentric distance between an axial lead of the inner ring (3) and an axial lead of the outer ring (1) can be adjusted by rotating the middle ring (2) so as to realize adjustment of the distance between shafts. A rolling bearing is respectively arranged on the outer side and the inner side of the middle ring (2),so that adjustment is very convenient, and torsion of adjustment is very little. A roller can be fixed reliably through locking of the middle ring after adjustment.
Description
Technical field
The utility model relates to a kind of bearing that is installed on the roll kind equipment, particularly a kind of bearing that can be installed in roll kind equipment adjusted distance between shafts.
Background technique
Have many machineries to have in actual life and be similar to this form: two parallel rolls, the gap that requires roll shop building are to determine reliably, and can regulate, and object can can't pass this gap by thick attenuation or blocked up object by this gap.In this this gap of class machinery adjusted is very important.
General method is at eccentric bushing of bearings mounted support hole, the two ends of roll mandrel neck bush, regulate gap between the roll by the angle of swing of regulating eccentric bushing, but this mode is because eccentric bushing and support hole are friction tight, regulate relatively difficulty, need to keep the long constantly debugging of parallel needs of roller just can finish.
The model utility content
Technical problem to be solved in the utility model provides a kind of off-centre of adjusting axle very easily to reach the bearing of realizing gap between roll mandrel.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of bearing of can regulate distance between shafts, comprise outer ring, centre circle and inner ring, be respectively arranged with outer rolling body, interior rolling element between centre circle and outer ring, the inner ring, outer rolling body, interior rolling element are fixed by outer retainer, interior retainer respectively.
Described centre circle is the eccentric bushing parts, and the outer surface of centre circle, internal surface are respectively arranged with two raceways, supplies outer rolling body, interior rolling element work respectively;
Described outer ring is two, and it is external to be separately positioned on outer rolling, and outer ring outer surface and support hole cooperate installs, and its internal surface is provided with raceway for outer rolling body running, the raceway cooperating on the raceway of inner surface and the centre circle outer surface;
Described inner ring is two, and outside the rolling element, the inner ring internal surface is installed on the roll mandrel by cooperation in being separately positioned on, and its outer surface is provided with raceway for interior rolling element work, the raceway cooperating on the raceway of inner ring outer surface and the centre circle internal surface;
Be respectively arranged with outer ring spacer, cone spacer between described outer ring and outer ring, inner ring and the inner ring.
In order to guarantee the bearing capacity of bearing, satisfy the usage requirement of machinery, described outer rolling body and interior rolling element are roller.
Because centre circle is an eccentric bushing, the rotation centre circle just can be regulated the eccentric distance of inner ring axis and outer ring axis, realizes the adjusting of distance between shafts, because the outside and the inboard of centre circle all are rolling bearings, so regulate very conveniently, the torsion of adjusting is very little.After finishing, adjusting only needs just stationary roll reliably of locking centre circle.
The beneficial effects of the utility model are: the rolling that inside and outside double roller is formed, make that the bearing capacity of bearing is very powerful, and satisfy the requirement of machinery heavy duty.Centre circle is in the middle of inside and outside rolling element, and coincide relative with rolling element rolled during adjusting, and rotational resistance is little, and is easy to adjust.The offset that centre circle is suitable can realize that twice offset adjusting car is by spacing.
Description of drawings
Accompanying drawing is a schematic representation of the present utility model.
Embodiment
As shown in drawings, a kind of bearing of can regulate distance between shafts, comprise outer ring 1, centre circle 2 and inner ring 3, be respectively arranged with outer rolling body 5, interior rolling element 4 between centre circle 2 and outer ring 1, the inner ring 3, outer rolling body 5, interior rolling element 4 are fixed by outer retainer 7, interior retainer 8 respectively.In order to guarantee the bearing capacity of bearing, satisfy the usage requirement of machinery, described outer rolling body 5 and interior rolling element 4 are roller.
Described centre circle 2 is the eccentric bushing parts, and the outer surface of centre circle 2, internal surface are respectively arranged with two raceways, respectively for outer rolling body 5,4 work of interior rolling element.
Described outer ring 1 is two, is separately positioned on outside the outer rolling body 5, and outer ring 1 outer surface and support hole cooperate installs, and its internal surface is provided with raceway for 5 work of outer rolling body, the raceway cooperating on the raceway of outer ring 1 internal surface and centre circle 2 outer surfaces.
Described inner ring 3 is two, and outside the rolling element 4, inner ring 3 internal surfaces are installed on the roll mandrel by cooperation in being separately positioned on, and its outer surface is provided with raceway for interior rolling element 4 work, the raceway cooperating on the raceway of inner ring 3 outer surfaces and centre circle 2 internal surfaces.
Be respectively arranged with outer ring spacer 6, cone spacer 9 between described outer ring 1 and outer ring 1, inner ring 3 and the inner ring 3.
Because centre circle 2 is eccentric bushings, the shaft axis of outer surface and internal surface has a definite throw of eccentric.Rotation centre circle 2 just can be regulated the eccentric distance of inner ring 3 shaft axiss and outer ring 1 shaft axis, the adjusting of realization distance between shafts, and owing to the outside and the inboard of centre circle 2 all is rolling bearings, so regulate very conveniently, the torsion of adjusting is very little.After finishing, adjusting only needs just stationary roll reliably of locking centre circle 2.
The rolling that inside and outside double roller is formed makes that the bearing capacity of bearing is very powerful, satisfies the requirement of machinery heavy duty.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
