Abstract
The utility model relates to a forklift combined side idler wheel which mainly comprises an outer ring, a shaft and a rolling assembly. The rolling assembly comprises a roller pin assembly and a steel ball assembly. The roller pin assembly and the steel ball assembly are arranged between the outer ring and the shaft at the same time. The forklift combined side idler wheel has the advantages that when a roller pin bearing bears axial loads, axial force is borne through the steel ball assembly, the roller pin assembly does not need to bear the axial force, the situation that when the whole bearing rotates, the roller pin bearing cannot rotate due to the fact that friction force between the roller pin assembly and the outer ring is overlarge can be avoided, abrasion on the roller pin assembly is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to the compound side wheel of a kind of fork truck, specifically a kind of bearing that can improve the suffered axial load of needle bearing.
Background technology
Fork truck refer to the member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short range transportation, weight transport operation.The fork truck side wheel that uses in existing market has two kinds, and a kind of is steel-ball type, and a kind of is needle-type.Traditional needle-type fork truck side wheel comprises anchor plate, side wheel and axle, side wheel is installed on the anchor plate by axle, its shortcoming is: the side wheel of fork truck in use, owing to be subjected to axial force, form cliding friction between side wheel end face and the anchor plate, easily cause stuck phenomenon after the anchor plate wearing and tearing, service life is short; And the steel-ball type side wheel comprises steel ball, back-up block and axle, and steel ball is installed on the anchor plate by axle, and its shortcoming is: the external diameter of side wheel is big, and the diametral load that can bear is little.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of bearing that can improve the suffered axial load of needle bearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the compound side wheel of a kind of fork truck, its innovative point is: mainly comprise outer ring, axle and rolling assembly, described rolling assembly comprises needle roller components and steel ball component, is provided with needle roller components and steel ball component simultaneously between described outer ring and the axle.
Further, described needle bearing is double row bearing, is respectively arranged with needle roller components and steel ball component in two raceways.
Further, described needle bearing is three race bearings, wherein is provided with needle roller components in Zhong Jian the raceway, is provided with steel ball component in the raceway on both sides.
Further, be provided with seal ring between described outer ring and the axle, described seal ring is positioned at the outside of rolling assembly.
Further, described steel ball is inserted in the needle bearing by filling out the segment mouth, the described segment mouth of filling out is made up of two parts, ecto-entad has been opened a U-shaped breach respectively on outer ring and axle, the U-shaped breach of the U-shaped breach of described outer ring and axle has constituted one jointly and has filled out the segment mouth, and bore reduces gradually from outside to inside, and it is littler than the bore of steel ball to fill out the inner most bore of segment mouth, and outermost bore is bigger than the bore of steel ball.
Advantage of the present utility model is: the needle bearing in the utility model, when bearing axial load, because the gap between steel ball component and outer ring and the axle is littler than needle roller components and the gap between them, therefore steel ball component can be born axial load fully, and needle roller components is because also leave the gap, so just need not to bear axial force, avoided whole bearing to cause situation about can't rotate when rotated owing to friction force between needle roller components and the outer ring is excessive, reduce the wearing and tearing to needle roller components, increased its service life.
