Abstract
The utility model discloses a sliding bearing for a drive axle. The sliding bearing for the drive axle is light in weight, convenient to manufacture, simple in structure, high in lubricating performance and long in service life. The sliding bearing for the drive axle is structured in the manner that a circular shaft sleeve is arranged and is formed by circumferentially alternatively distributing, laminating and pressing modified phenolic resin layers and cotton fiber fabrics; circumferential oil guide grooves and axial oil guide grooves are manufactured on the internal wall of the shaft sleeve; and oil pouring holes communicated with the external surface of the shaft sleeve are formed in the oil guide grooves. The sliding bearing for the drive axle, disclosed by the utility model, is structured by alternatively pressing the modified phenolic resin and the cotton fiber fabrics; the modified phenolic resin is that the graphite can be added to the phenolic resin, which has the abrasion resistance higher than that of common phenolic resin; the cotton fiber fabrics served as interlayer are just like adding reinforcing steel bars in concrete, so that the shaft sleeve has the flexibility and bending resistance higher than those of conventional single shaft sleeve made from phenolic material, and the service life and strength are greatly prolonged and improved respectively; the structure of the sliding bearing for the drive axle can be more compact; and the siding bearing is applicable to the drive axle of heavy engineering machinery or the drive axle of a large vehicle.
Description
Technical field
The utility model relates to sliding bearing, more specifically to ransaxle sliding bearing in vehicle or the engineering machinery.
Background technique
The engineering machinery of various vehicles, large-scale heavy duty, such as loader, excavator, bulldozer etc., ransaxle is positioned at the end of Power Train, although rotating speed is not high, the moment of torsion that transmits is large, especially on semiaxis.Therefore, the bearing on ransaxle is owing to low-speed heave-load, and in use they are not only bearing very high load and lateral force, also mix simultaneously along with strong impact endurance test shock, and its operating mode is extremely abominable.Usually these positions are the rolling bearings with large specification, but lose efficacy early, and the rolling bearing size is restricted in structural design greatly.
The model utility content
The purpose of this utility model be to provide a kind of lightweight, easily manufactured, simple in structure, greasy property is good, the ransaxle sliding bearing of long service life.
In order to reach above-mentioned requirements, the technological scheme of this model utility: it is characterized in that it circumferentially is alternately distributed the round sleeve that stacked pressing forms by phenol-formaldehyde resin modified layer and cotton fiber cloth, be shaped with the oil guide slot of circumferential and axial at the inwall of axle sleeve, in oil guide slot, be shaped with the oil hole that communicates with the axle sleeve appearance.
Ransaxle sliding bearing according to the such scheme manufacturing, because its structure adopts phenol-formaldehyde resin modified and cotton fiber cloth to join and forms, phenol-formaldehyde resin modified is to add graphite in phenolic resin, it has better Wear vesistance than common phenolic resin, and make interlayer as having added reinforcing bar in the concrete with cotton fiber cloth, it more has pliability and anti-bending strength than existing independent phenolic materials axle sleeve, and working life and intensity improve greatly.And the wall ratio rolling bearing of sliding bearing is much smaller, can be with structural design compacter, be fit to be used as the sliding bearing of the ransaxles such as heavy engineering machinery, large vehicle.
Description of drawings
Fig. 1 is the plan view that ransaxle is used sliding bearing.
Wherein: 1, phenol-formaldehyde resin modified layer; 2, cotton fiber cloth; 3, oil guide slot; 4, oil hole.
Embodiment
Below in conjunction with accompanying drawing the utility model content is further described.
Fig. 1 ransaxle structural representation of sliding bearing.It circumferentially is alternately distributed the round sleeve that stacked pressing forms with the phenol-formaldehyde resin modified layer 1 that adds graphite in the phenolic resin with cotton fiber cloth 2 as seen from the figure, be shaped with the oil guide slot 3 of circumferential and axial at the inwall of axle sleeve, in oil guide slot 3, be shaped with the oil hole 4 that communicates with the axle sleeve appearance.
