Abstract
The utility model relates to an adjustable composite bearing, which comprises an inner ring, an outer ring, a roll column and a shaft head. The roll column is arranged between the inner ring and the outer ring, the shaft head is bolted in the inner ring, the end face of the shaft head is provided with a cavity, the two sides of the cavity is provided with a clamping slot, and a side roller is arranged in the cavity and is formed by arranging a roller needle between a side outer roller ring and a side eccentric roller shaft; and the end part of the side eccentric roller shaft adopts a regular hexagonal structure, and two parallel edges at the end of the side eccentric roller shaft can be just embedded in the clamping slots arranged on the two sides of the cavity of the shaft head. The utility model has the advantages that: when the extension length of the side outer roller ring is to be adjusted, the side eccentric roller shaft is removed, rotated for a certain angle and then embedded again into the clamping slots, and the length of the part of the side outer roller ring extending out of the end face of the shaft head can be changed under action of the side eccentric roller shaft. No reprocessing or remanufacture is needed, thus the adjustment is convenient and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of can regulate composite bearing.
Background technique
Common composite bearing is that main roller adds unadjustable side wheel bearing, promptly establish side wheel at the spindle nose end face of main bearing, the distance that this kind fork truck bearing can't be regulated side wheel projecting shaft end surface, if the back side wheel is installed can't be close to door frame, then need installation is reorientated, adjusted to this bearing, adjust trouble, efficient is low, the fabricating cost height.
The model utility content
The technical problems to be solved in the utility model provides the adjustable composite bearing of a kind of side wheel extrusion.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of can regulate composite bearing, comprise inner ring, outer ring, roller and spindle nose, be provided with roller between inner ring and the outer ring, bolt has spindle nose in the inner ring, and its innovative point is: described spindle nose end face has cavity, and the cavity both sides are provided with draw-in groove, be provided with side wheel in the described cavity, this side wheel constitutes by establishing needle roller between side wheel outer ring and the side wheel eccentric shaft; Described side wheel eccentric shaft end is the regular hexagon structure, and two limits of its end parts parallel just can embed in the draw-in groove of spindle nose cavity both sides setting.
Advantage of the present utility model is: when needing to regulate side wheel outer ring extrusion, take out the side wheel eccentric shaft, embed in the draw-in groove after it is rotated to an angle again, change the distance of side wheel outer ring projecting shaft end surface by the effect of side wheel eccentric shaft.Need not to carry out processing and fabricating again, easy to adjust, reduce production costs.
Description of drawings
Accompanying drawing is the utility model can regulate composite bearing structure schematic representation.
Embodiment
As shown in drawings, comprise inner ring 1, outer ring 2, roller 3, spindle nose 4, draw-in groove 5, side wheel outer ring 6, side wheel eccentric shaft 7, needle roller 8.
Be provided with roller 3 between above-mentioned inner ring 1 and the outer ring 2, be provided with in inner ring 1 and the fixing spindle nose 4 of its bolt, the end face of this spindle nose 4 has cavity, and the cavity both sides are provided with draw-in groove 5.
Side wheel is installed in the cavity, and it constitutes by establishing needle roller 8 between side wheel outer ring 6 and the side wheel eccentric shaft 7, the two-end part regular hexagon structure of side wheel eccentric shaft 7, and two parallel in its end hexagonal structure limits just can embed in the draw-in groove 5.
When needing to regulate side wheel outer ring 6 extrusions, take out side wheel eccentric shaft 7, after it is rotated to an angle, make two outer two parallel limits embed in the draw-in groove 5, under the effect of side wheel eccentric shaft 7, change the distance that spindle nose 4 end faces are stretched out in side wheel outer ring 6.
Claims (1)
1. can regulate composite bearing, comprise inner ring, outer ring, roller and spindle nose, be provided with roller between inner ring and the outer ring, bolt has spindle nose in the inner ring, it is characterized in that: described spindle nose end face has cavity, the cavity both sides are provided with draw-in groove, are provided with side wheel in the described cavity, and this side wheel constitutes by establishing needle roller between side wheel outer ring and the side wheel eccentric shaft; Described side wheel eccentric shaft end is the regular hexagon structure, and two limits of its end parts parallel just can embed in the draw-in groove of spindle nose cavity both sides setting.
