Description
Technical field
The utility model relates to a kind of guide wheel assembly.
Background technique
Existing guide wheel assembly, include positioning shaft, bearing, guide wheel body, described positioning shaft is provided with axle bearing mount portion, described bearing housing is located on axle bearing mount portion, described guide wheel body is set in outside bearing, described positioning shaft is positioned at axle bearing mount portion both sides and is provided with draw-in groove, be provided with jump ring in described draw-in groove, in order to support material well, guide wheel body is that cast iron is made.But the guide wheel assembly of this structure, because guide wheel body is that cast iron is made, make the quality of guide wheel body large like this, long-time use can make positioning shaft produce distortion.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of guide wheel assembly, and it greatly reduces the quality of guide wheel body, thus can prevent positioning shaft from producing distortion, and, the conveying to material can not be affected.
The technical solution of the utility model: a kind of guide wheel assembly, include positioning shaft, bearing, guide wheel body, described positioning shaft is provided with axle bearing mount portion, described bearing housing is located on axle bearing mount portion, described guide wheel body is set in outside bearing, described positioning shaft is positioned at axle bearing mount portion both sides and is provided with draw-in groove, jump ring is provided with in described draw-in groove, it is characterized in that: described guide wheel body includes the castiron outer ring that split is arranged, be arranged on the inner ring that the aluminum alloy in outer ring is made, described inner ring is set in outside bearing, described outer ring is fixedly connected with through locating stud with inner ring.
Adopt technique scheme, the split of guide wheel body arranged, inner ring is that aluminum alloy is made, and greatly reduces the quality of guide wheel body like this, thus can prevent positioning shaft from producing distortion; Outer ring is that cast iron is made, and can not affect the conveying to material like this.
Further setting of the present utility model: the end face of at least side of described outer ring has extended internally location piece, on described inner ring, corresponding location piece position is provided with locating slot, described location piece is plugged in locating slot, and described locating stud is plugged in locating slot through location piece.
Adopt above-mentioned further setting, the outer ring of this structure, inner ring Placement, structure is simple, and intensity is high, is not easy to produce distortion.
Of the present utility modelly to arrange further again: the end face of described both sides, outer ring has all extended internally location piece, and the end face alignment of described outer ring, inner ring both sides is arranged.
Adopt and above-mentionedly to arrange further again, guide wheel body can being made so more steady when rotating, can not inclination be produced.
Further setting more of the present utility model: the location piece on side end face, outer ring one is provided with at least four, and the central shaft of described location piece around outer ring is uniformly distributed.
Adopting and above-mentionedly further to arrange again, this location piece set-up mode, guide wheel body can being made more steady when rotating, stressed more even, be not easy to produce distortion.
Further setting more of the present utility model: the described diameter being positioned at the positioning shaft of axle bearing mount portion is greater than the diameter of the positioning shaft being positioned at axle bearing mount portion both sides.
Adopt and above-mentionedly further to arrange again, can make when being enclosed within axle bearing mount portion from any side of positioning shaft by bearing, bearing can not contact with the positioning shaft being positioned at axle bearing mount portion both sides, thus reduces wear, and guide wheel body is rotated more steady.

Embodiment
As Figure 1-4, a kind of guide wheel assembly, include positioning shaft 1, bearing 2, guide wheel body 3, described positioning shaft 1 is provided with axle bearing mount portion 11, described bearing 2 is set on axle bearing mount portion 11, described guide wheel body 3 is set in outside bearing 2, described positioning shaft 1 is positioned at axle bearing mount portion 11 both sides and is provided with draw-in groove 12, jump ring 4 is provided with in described draw-in groove 12, described guide wheel body 3 includes the castiron outer ring 31 that split is arranged, be arranged on the inner ring 32 that the aluminum alloy in outer ring 31 is made, described inner ring 32 is set in outside bearing 2, described outer ring 31 is fixedly connected with through locating stud 5 with inner ring 32.Guide wheel body 3 split arranged, inner ring 32 is made for aluminum alloy, greatly reduces the quality of guide wheel body 3 like this, thus can prevent from positioning shaft 1 from producing being out of shape; Outer ring 31 is made for cast iron, can not affect the conveying to material like this.
In the utility model specific embodiment, the end face of described both sides, outer ring 31 is inwardly all extended with location piece 311, on described inner ring 32, corresponding location piece 311 position is provided with locating slot 321, described location piece 311 is plugged in locating slot 321, described locating stud 5 is plugged in locating slot 321 through location piece 311, and the end face alignment of described outer ring 31, inner ring 32 both sides is arranged.The outer ring 31 of this structure, inner ring 32 Placement, structure is simple, and intensity is high, is not easy to produce distortion, and, guide wheel body 3 can being made more steady when rotating, can not inclination be produced.In the utility model specific embodiment, location piece 311 on side end face, outer ring 31 1 is provided with four, the described central shaft of location piece 311 around outer ring 31 is uniformly distributed, this location piece set-up mode, guide wheel body 3 can be made more steady when rotating, stressed more even, be not easy to produce distortion.
In the utility model specific embodiment, the diameter of the described positioning shaft 1 being positioned at axle bearing mount portion 11 is greater than the diameter of the positioning shaft 1 being positioned at axle bearing mount portion 11 both sides, can make when by bearing 2, from positioning shaft 1, side is enclosed within axle bearing mount portion 11 arbitrarily like this, bearing 2 can not contact with the positioning shaft 1 being positioned at axle bearing mount portion 11 both sides, thus reduce wear, guide wheel body 3 is rotated more steady.
