Abstract
The utility model relates to a built-in side idler wheel side positioning structure which comprises a main idler wheel, a shaft head, a side idler wheel and a side idler wheel support, wherein the main idler wheel is mounted on the shaft head in a sleeved mode, the top end face of the shaft head is provided with a cylindrical inner cavity, and the side idler wheel support is arranged in the inner cavity. The side idler wheel is mounted on the side idler wheel support through a side idler wheel shaft, the side idler wheel is higher than the top end face of the shaft head, a threaded hole arranged at the center of the bottom end face of the shaft head is connected with an adjusting screw, the top end of the adjusting screw abuts against the bottom surface of the side idler wheel support, a side face of the side idler wheel support is provided with a positioning groove which extends along the axial direction of the shaft head, the shaft head is provided with a through hole which runs through a side of the cylindrical inner cavity of the shaft head and an outer wall of the shaft head, a positioning pin is mounted in the through hole, and the end portion of the positioning pin is embedded into the positioning groove. The positioning pin embedded in the positioning groove is used for limiting the side idler wheel support so as to ensure that eccentric rotation of the side idler wheel support caused by shaking of a forklift gantry does not occur, so that the side idler wheel can normally roll along a gantry track, and rate of wear is reduced.
Description
Technical field
The utility model relates to a kind of built-in side wheel side location structure, particularly a kind of built-in side wheel side location structure of long service life.
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 of long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of built-in side wheel side 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: described side roller brackets side is provided with along the axially extended positioning groove of spindle nose, is drilled with the through hole that connects spindle nose cylindrical cavity sidewall and spindle nose outer wall on the spindle nose; The locating dowel pin that the end embeds positioning groove is installed in the described through hole.
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 positioning groove in the spindle nose spacing to side roller brackets, 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 side location structure structural representation 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 7, 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 along the axially extended positioning groove 7 of spindle nose in side roller brackets 3 sides, the cylindrical cavity sidewall of spindle nose 2 is drilled with circle or the square opening 8 corresponding with positioning groove 7, and this hole 8 is for connecting the through-hole structure of spindle nose cylindrical cavity sidewall and spindle nose outer wall; The locating dowel pin 9 that the end embeds positioning groove 7 is installed, hole 8 and locating dowel pin 9 interference fit in this hole 8.
Claims (1)
1. built-in side wheel side 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: described side roller brackets side is provided with along the axially extended positioning groove of spindle nose, is drilled with the through hole that connects spindle nose cylindrical cavity sidewall and spindle nose outer wall on the spindle nose; The locating dowel pin that the end embeds positioning groove is installed in the described through hole.
