Abstract
The invention relates to a sidewise roller bearing used for a support. The sidewise roller bearing comprises a side roller support, a side roller and a shaft. The side roller is sleeved on the shaft through an inner hole and the two ends of the shaft are fixed on the side roller support. The sidewise roller bearing is innovated in that a mounting hole with the diameter bigger than the diameter of the inner hole is coaxially arranged at the end part of the inner hole of the side roller, and a step face between the mounting hole and the inner hole forms a flange; a shaft washer which is sleeved on the shaft and is in interference fit with the shaft is arranged in the mounting hole; and a retainer rolling element assembly is arranged between the shaft wafer and the flange. According to the invention, the shaft wafer and the retainer rolling element assembly are arranged in the mounting hole at the end face of the side roller, the shaft wafer, the retainer rolling element assembly and the flange of the side roller form a thrust bearing, which enables the sidewise roller bearing to have the ability of bearing axial loads. Meanwhile, compared with the manner of directly embedding a thrust bearing, the sidewise roller bearing has the advantages that a housing wafer is saved, the axial size of the bearing is reduced, the contact length between the side roller and the shaft is prolonged while the overall size of the bearing remains unchanged, and the radial bearing capacity of the bearing is improved.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of support is used side direction roller bearing.
Background technique
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; Being widely used in national economy all departments such as station, harbour, airport, factory, warehouse, is the high-efficiency appliance of mechanized handling, stacking and short distance transportation.The vehicle frame sidesway of fork truck need use side direction roller bearing, requires to bear simultaneously bigger radial load and certain thrust load.
Number of patent application 200920314140.0 discloses a kind of side wheel bearing, and it comprises mandrel, suit outer ring on mandrel; Establish needle roller between mandrel and the outer ring; Establish the thrust circle at the needle roller two ends, the thrust circle is through the snap ring axial restraint, and the seal ring that is socketed on the mandrel is established in the end of outer ring.This structure utilizes thrust circle and snap ring to the outer ring axial limiting, improves the axial bearing capacity of bearing, but serious wear between the rib of thrust circle and outer ring is used still to receive certain limitation.
In addition, also have split bearing manufacturing enterprise to adopt built-in thrust bearing, its structure comprises side wheel support, side wheel and axle, and side wheel is contained on the axle through inner hole sleeve, and the two ends of axle are fixed on the side wheel support, at the side wheel two ends thrust-bearing are set.Though this kind structure can be avoided wearing and tearing faster because boundary dimension restriction, thrust-bearing is set after, side wheel diminishes with the contact length of axle, has influenced the ability of carrying radial load.
Summary of the invention
The technical problem that the present invention will solve provides a kind of support that can on the basis that does not change boundary dimension, improve radial load and uses side direction roller bearing.
For solving the problems of the technologies described above; Technological scheme of the present invention is: a kind of support is used side direction roller bearing; Comprise side wheel support, side wheel and axle, side wheel is contained on the axle through inner hole sleeve, and the two ends of axle are fixed on the side wheel support; Its innovative point is: the end of said side wheel is provided with mounting hole, forms step surface or rib between mounting hole and the endoporus; Be provided with in the mounting hole and be sleeved on the blowout patche on the axle, blowout patche and axle interference fit are provided with retainer rolling element assembly between blowout patche and the rib.
Further, be provided with self oiling bearing between the endoporus of said side wheel and the axle.
Further, between the endoporus of said side wheel and the axle needle roller is set.
Further, said retainer rolling element assembly is the needle roller components of band retainer.
Further, the said blowout patche end face exterior edge face of stretching out side wheel.
The invention has the advantages that: blowout patche and retainer rolling element assembly are set in the end face mounting hole of side wheel, and blowout patche, retainer rolling element assembly and side wheel constitute a thrust-bearing, make side direction roller bearing have the ability of carrying thrust load.Simultaneously, compare the thrust-bearing of directly inlaying common complete structure and saved seat ring, reduce axial dimension, make prolong under the constant situation of overall dimensions self oiling bearing in the side wheel, needle roller with spool contact length, area, improve radially bearing capacity.
