本文介绍一种新型结构的行走轮(作者发明证书929532),即桥式吊、龙门吊和塔吊运行机构的行走轮,采用此种结构,可大大地提高其使用寿命。如图所示。图中1、2、3分别表示行走轮的轮毂、轮盘、轮缘。用螺栓把可换弹性轮缘4和非弹性轮缘5紧固在行走轮的环槽内。在非弹性轮缘的槽内装有橡胶圈,以使两个轮缘(4、5)相隔离。为了便于装配,将轮缘和橡胶圈先分装在一起。为增强柔韧性在弹性轮缘内做出一些径向槽,在吊车承载运动时,钢轨和行走轮之间可能会产生弯曲变形.此时钢轨侧面紧压弹性轮缘,使其弯曲变形,同时压紧橡胶圈。卸载后弯曲变形消失,弹性轮缘和橡胶圈恢复了原有的形状,这种结构的行走轮可提高使用周期,因为轮缘有较高的变形能力,所以可减小行走轮与钢轨之间的摩擦力。此外,
This article describes a new type of walking wheel (author’s invention certificate 929532), that is, bridge crane, gantry crane and tower crane running wheels, using this structure, can greatly improve its service life. as the picture shows. Figure 1, 2, 3, respectively, said the wheels wheel, wheel, rim. Bolt the interchangeable elastic rim 4 and the non-elastic rim 5 in the groove of the running wheel. A rubber ring is fitted in the groove of the inelastic rim to isolate the two rims (4, 5). In order to facilitate the assembly, the rim and the rubber ring first sub-packed together. In order to increase the flexibility, some radial grooves are made in the elastic rim, and bending deformation may occur between the rail and the traveling wheel when the crane is carrying the load. At this time, the rail side is pressed against the elastic rim to make it bend and deform, meanwhile Compression rubber ring. Unloading bending deformation disappears, the elastic rim and the rubber ring restored to its original shape, this structure of the running wheel can improve the life cycle, because the rim has a higher deformation capacity, it can reduce the distance between the running wheel and the rail Friction. In addition,
