Abstract
The utility model relates to a gap-adjustable eccentric side roller bearing which is characterized by comprising a main roller component, a shaft head, a side roller component and a side roller shaft, the main roller component is mounted outside shaft head, the side roller shaft whose axis is perpendicular to the axis of the shaft head is mounted on the shaft head, the side roller component is mounted on the side roller shaft, and the side roller shaft is an eccentric shaft. The gap-adjustable eccentric side roller bearing has the advantages that when a gap between the side roller and portal channel steel occurs during mounting or after long-term use, the eccentric shaft can be rotated at certain angle relative to the shaft head to change the distance of the outer surface, extending out of the shaft head, of the roller on the upper side of the eccentric shaft so as to adjust the gap between the side roller and portal channel steel to be reasonable, replacing or remachining of the side roller is unnecessary, mounting and maintenance are more convenient, and application cost is lowered.
Description
Technical field
The utility model relates to a kind of side wheel, particularly a kind of clearance adjustable type eccentric side roller bearing.
Background technology
Fork truck uses on forklift door frame, goods shelf with side wheel, it need to rotatablely move on both direction, due to the locus restriction, the general composite rolling wheel structure that rotatablely moves with both direction right-angled crossing direction that adopts, it mainly comprises main roller assembly, spindle nose, side wheel, sidewinders wheel shaft, the main roller assembly is arranged on spindle nose, and built-in vertical with the spindle nose axis wheel shaft that sidewinders of spindle nose sidewinders installation side roller on wheel shaft.The shortcoming of at present traditional side wheel is: when mounted, or after using wearing and tearing for a long time, have the gap between side wheel and gantry channel-steel, processing or replacing side wheel, install, safeguard inconvenience again, increases cost.
Some clearance adjustable type side wheels have appearred at present on the market, for example CN201012895 discloses a kind of adjustable main side roller unit, its structure comprises the main roller assembly side wheel outer with being enclosed within bearing pin that is enclosed within outside spindle nose, be provided with axle bed between side wheel and spindle nose, a side at axle bed is provided with governing screw, and governing screw and spindle nose are threaded connection.Its side wheel and channel-section steel gap can be adjusted; But still there is certain defective: when propping up axle bed, governing screw easily causes the damage of axle bed, and complex structure, need to use axle bed, increased cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide the low clearance adjustable type eccentric side roller bearing of a kind of capable of regulating side wheel and forklift door frame channel-section steel gap and cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of clearance adjustable type eccentric side roller bearing, its innovative point is: comprise main roller assembly, spindle nose, side wheel assembly, sidewinder wheel shaft, the main roller assembly is arranged on outside spindle nose, install on spindle nose axis vertical with the spindle nose axis sidewinder wheel shaft, sidewinder installation side roll wheel assembly on wheel shaft; The described wheel shaft that sidewinders is eccentric shaft.
Further, described eccentric shaft and spindle head connecting structure are: the shaft shoulder cross-sectional plane at eccentric shaft two ends is equilateral polygon, and the eccentric shaft mounting groove of spindle nose is processed into the equilateral polygon groove structure that matches with the eccentric shaft shaft shoulder.
Further, described eccentric shaft and spindle head connecting structure are: the shaft shoulder cross-sectional plane at eccentric shaft two ends is profile of tooth, and the eccentric shaft mounting groove of spindle nose is processed into the serrate slot structure that matches with the eccentric shaft shaft shoulder.
The utility model has the advantage of: when mounted or long-term use cause side wheel and gantry channel-steel generation gap after, eccentric shaft is rotated certain angle relative to spindle nose, change the distance that on eccentric shaft, the side wheel outside face stretches out spindle nose, and then adjust side wheel with gantry channel-steel to rational gap, need not to change or process side roller again, install, safeguard convenient, and reduce use cost.
Description of drawings
Fig. 1 is the utility model clearance adjustable type eccentric side roller bearing structural representation.
Fig. 2 is the clearance adjustable type eccentric side roller bearing structural representation of the another kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the main roller assembly comprises main roller outer ring 1, main roller inner ring 2, rolling body 3, rib 4, rolling body 3 is installed in the raceway that forms between main roller inner ring 2 and main roller outer ring 1 in the outer suit main roller of main roller inner ring 2 outer ring 1, and rolling body 3 is spacing by rib 4.It will be understood by those skilled in the art that it is only exemplary here, is not restricted.
The main roller assembly is arranged on outside spindle nose 5, install on spindle nose 5 axis vertical with spindle nose 5 axis sidewinder wheel shaft 6, this sidewinders wheel shaft 6 and is arranged in the axle mounting groove of spindle nose 5, and is fixed by rib 4, sidewinder installation side roll wheel assembly 7 on wheel shaft 6, side wheel 6 is eccentric shaft.
Claims (3)
