MEJORAS EN RODAJA DE RUEDAS DOBLES Y EJE INCLINADO CON UN RETEN Y UN COJINETE INTEGRALES

摘要

A dual wheel caster (10) comprises a body (12) upon which a pair of wheels (40) are rotatably mounted by means of a bearing assembly (58). The rollers of the bearing assembly run on an inner race defined by a cylindrical sleeve (22) integral with the body and an outer race defined by an interior surface of the wheel (40). A ball bearing (82) runs on a flange (54) of the wheel (44) and on a cover (72) which is secured to the body in order to transmit outward thrust loading from the wheel to the body. The bearings (58,82) are formed initially as respective integral mouldings from which the rollers/balls are broken free during assembly and first use of the caster.
