Abstract
The invention relates to a composite side rolling wheel of a forklift. The composite side rolling wheel mainly comprises an outer ring, a shaft and a rolling assembly, wherein the rolling assembly comprises a rolling pin assembly and a steel ball assembly, and the rolling pin assembly and the steel ball assembly are simultaneously arranged between the outer ring and the shaft. The composite side rolling wheel has the advantages that a rolling pin bearing bears the axial force by using the steel ball assembly while bearing an axial load, and the rolling pin assembly does not need to bear the axial force, so that the condition that the whole bearing is unable to rotate caused by overlarge frictional force between the rolling pin assembly and the outer ring in the rotating process is avoided, the abrasion to the rolling pin assembly is reduced and the service life of the rolling pin assembly is prolonged.
Description
Technical field
The present invention relates to the compound side wheel of a kind of fork truck, a kind of specifically bearing that can improve the suffered axial load of needle bearing.
Background technology
Fork truck be meant to the member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short-distance 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 by axle mounting on anchor plate, 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 on anchor plate, its shortcoming is steel ball by axle mounting: the external diameter of side wheel is big, and the diametral load that can bear is little.
Summary of the invention
The technical problem to be solved in the present invention 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 used in the present invention 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 a 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 type breach respectively on outer ring and axle, the U type breach of the U type 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.
The invention has the advantages that: the needle bearing among the present invention, 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, reduced wearing and tearing, increased its service life needle roller components.
