The invention discloses a wheel convenient to replace and provided with self-lubricating rims, and relates to hoisting machinery. Due to factors such as wheel deflection, a crane gnaws a rail to operate, especially when an operating mechanism is high in working level, the service life of a rim is far shorter than that of a wheel tread, and therefore a wheel is scrapped too early due to rim abrasion. A structural form that the rims are replaceable is adopted, no matter a single-rim wheel or a double-rim wheel, the rim on each side is divided into a plurality of sections of arcs, the rims are fixed on a wheel body by bolts, and a certain proportion of solid lubricant is embedded in the rim friction surfaces, so that the lubricating condition of a friction pair formed by the rims and the sidesurface of a steel rail is improved. The service life of the rims and the steel rail is prolonged, the friction resistance of crane operation is reduced, when the rim abrasion reaches the scrap degree, the rims can be replaced under the condition that a wheel set is not disassembled, the rims are made of high-strength wear-resisting plates, a heat treatment manufacturing procedure is omitted, therims and the wheel body are manufactured separately, and die forging of the wheel body becomes possible.

    本发明公开了一种便于更换且具有自润滑轮缘的车轮,涉及起重机械,因车轮偏斜等因素,造成起重机啃轨运行,尤其是运行机构工作级别较高时,轮缘寿命远低于车轮踏面寿命,使得车轮因轮缘磨损而过早报废,本发明采用轮缘可更换的结构形式,无论是单轮缘车轮还是双轮缘车轮,每侧轮缘分成几段圆弧,用螺栓将轮缘固定在车轮本体上,在轮缘摩擦面镶嵌一定比例固体润滑剂,以此改善轮缘与钢轨侧面所构成的摩擦副的润滑条件,延长轮缘与钢轨的使用寿命,减小起重机运行的摩擦阻力,当轮缘磨损达到报废程度时,可在不拆卸车轮组的情况下,更换轮缘,轮缘材料采用高强度耐磨板,省去热处理制造工序,轮缘与车轮本体分开制造,使得车轮本体采用膜锻成为可能。
