Abstract
The utility model relates to an end positioning structure for an internal lateral roller. The end positioning structure comprises a main roller, a shaft head, a lateral roller and a lateral roller support. The main roller is sleeved on the shaft head, the top end of the shaft head is provided with a cylindrical inner cavity, the lateral roller support is disposed in the inner cavity, the lateral roller is disposed on the lateral roller support through a lateral roller shaft, and the lateral roller is higher than the top end of the shaft head; and a central threaded hole at the bottom end of the shaft head is connected with an adjusting screw, and the top end of the adjusting screw is abutted to the bottom of the lateral roller support. The end positioning structure for the internal lateral roller is characterized in that the bottom of the lateral roller support is provided with a positioning hole, through holes penetrate through the bottom of the cylindrical inner cavity and the bottom of the shaft head are drilled on the shaft head, and the top end of a positioning pin penetrates through the through holes to be in interference fit with the positioning hole. The lateral roller support is limited by the positioning pin embedded in the positioning hole in the shaft head, and accordingly end positioning is achieved, the lateral roller support is guaranteed to be free of deviation due to vibration of a forklift doorframe when a composite bearing is in use, the lateral roller can roll along a rail of the doorframe normally and speed of wear is reduced.
Description
Technical field
The utility model relates to a kind of built-in side wheel, particularly a kind of built-in side wheel end face location structure.
Background technology
Forklift door frame need to be realized rotatablely moving at both direction with bearing, because locus restriction, normal operation has the composite rolling wheel structure that rotatablely moves of both direction right-angled crossing direction, and it is built-in side roller brackets in the bearing of routine, installation side roller on side roller brackets.The built-in side wheel of a kind of fork truck is disclosed such as license notification number CN 201250086Y, it is by spindle nose, side roller brackets, side wheel, little axle, spindle nose is installed plain bearing outward as main roller, the built-in side roller brackets of spindle nose, and side roller brackets is by little axle installation side roller.This kind structure has compact conformation, and the advantage that volume is little extensively adopts on the forklift door frame bearing.But still have certain disadvantages: because the side roller brackets profile is cylindrical structural, during use, side wheel props up forklift door frame, and there is certain vibration in forklift door frame in motion process, so that certain deflection easily occurs in side roller brackets in spindle nose, so that side wheel can't work, accelerated wear test, service life is lower.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of built-in side wheel side location structure in service life that prolongs.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of built-in side wheel end face location structure, comprise main roller, spindle nose, side wheel and side roller brackets, described main roller is sleeved on the spindle nose, open cylindrical cavity on the spindle nose top end face, be built-in with side roller brackets in the inner chamber, side roller brackets is by sidewindering wheel shaft installation side roller, and side wheel exceeds the spindle nose top end face; The bottom face screwed hole of centre of described spindle nose is connected with governing screw, the top of governing screw props up the bottom surface of side roller brackets, its innovative point is: the bottom surface of described side roller brackets is provided with knock hole, be drilled with the through hole that connects cylindrical cavity bottom surface and spindle nose bottom face on the described spindle nose, the top of locating dowel pin is passed behind the through hole and the knock hole interference fit.
Further, described through hole is a pair of, and the line of described two through hole passes the bottom center of spindle nose.
The utility model has the advantage of: after the side wheel wearing and tearing, can promote side roller brackets by the locking governing screw and move axially along spindle nose, in order to keep side wheel and door frame to fit, avoid loosening.Utilize the locating dowel pin that embeds knock hole in the spindle nose spacing to side roller brackets, realization end face location, guarantee that this combination bearing in use can not cause owing to the vibration of forklift door frame the deflection of side roller brackets, so that side wheel can roll along the door frame track normally, reduce the rate of wear.
Description of drawings
Fig. 1 is built-in side wheel end face location structure scheme drawing in the utility model.
Fig. 2 is spindle nose cutaway view in the utility model.
The specific embodiment
As shown in Figure 1, 2, comprise main roller 1, spindle nose 2, side roller brackets 3, sidewinder wheel shaft 4, side wheel 5, governing screw 6, positioning groove, hole 8, locating dowel pin 9.
Above-mentioned main roller 1 is sleeved on the spindle nose 2, and inner ring one side of main roller 1 is spacing by the step of spindle nose 2, and opposite side is spacing by the shaft block ring that embeds spindle nose 2.
The top end face of spindle nose 2 has columniform inner chamber, and built-in side roller brackets 3 in the inner chamber is equipped with side wheel 5 by sidewindering wheel shaft 4 on the side roller brackets 3, and the part outside face of side wheel 5 stretches out the top end face of spindle nose 2.The bottom face center of spindle nose 2 is provided with the tapped bore that is communicated with cylindrical cavity, and the tapped bore negative thread is connected with governing screw 6, and the top of governing screw 6 props up the bottom surface of side roller brackets 3.
Be provided with a knock hole 10 in the bottom surface of side roller brackets 3, be drilled with hole 8 on the spindle nose 2, this hole 8 is for connecting the through hole of cylindrical cavity bottom surface and spindle nose 2 bottom faces, the diameter of locating dowel pin 9 is slightly less than the internal diameter of through hole, the slightly larger in diameter of locating dowel pin 9 is in the internal diameter of knock hole 10, and the top of locating dowel pin 9 is passed behind the through hole and knock hole 10 interference fit.
In the present embodiment, as shown in Figure 2, hole 8 is a pair of through hole, and the line of two through hole passes the bottom center of spindle nose 2.Its advantage is: when the installation of carrying out side roller brackets 3 and spindle nose 2, first locating dowel pin 9 is hammered in the knock hole 10, the line of the axis that sidewinders wheel shaft 4 and two through hole is corresponding after, can guarantee in the arbitrary through hole of embedding of locating dowel pin 9 the raising installation effectiveness.
Claims (2)
1. built-in side wheel end face location structure, comprise main roller, spindle nose, side wheel and side roller brackets, described main roller is sleeved on the spindle nose, open cylindrical cavity on the spindle nose top end face, be built-in with side roller brackets in the inner chamber, side roller brackets is by sidewindering wheel shaft installation side roller, and side wheel exceeds the spindle nose top end face; The bottom face screwed hole of centre of described spindle nose is connected with governing screw, the top of governing screw props up the bottom surface of side roller brackets, it is characterized in that: the bottom surface of described side roller brackets is provided with knock hole, be drilled with the through hole that connects cylindrical cavity bottom surface and spindle nose bottom face on the described spindle nose, the top of locating dowel pin is passed behind the through hole and the knock hole interference fit.
