I.巧取变速器第二轴上的小伞齿轮固定螺母 洛阳建筑机械厂原生产的3Y8/10、3Y18/21T型静压三轮压路机,其变速器第二轴上的小伞齿轮是采用六角螺母来固定的,并用自制的止动垫防松。机器在使用过程中,由于第二轴作双向转动,且双向旋转的力矩较大,故易造成螺母松动,时间一长,止动垫的包角就失去了对螺母的止退作用。最终造成螺母因松脱而掉入变速器内。若未能及时取出,将造成以下后果;差速器的轮齿被挤坏或卡住;第二 I. Clever take the small shaft gear on the second shaft fixed nut Luoyang Construction Machinery Factory, the original production of 3Y8 / 10,3Y18 / 21T-type hydrostatic three-wheeled roller, the transmission of the small bevel gear on the second axis is the use of hex nuts To be fixed, and use the self-made stopper to prevent loose. During the process of using the machine, the second shaft rotates bidirectionally and the torsional torque in two-way rotation is relatively large, so the nut can be easily loosened. Over time, the corner of the stop pad loses its function of stopping the nut. Eventually causing the nut to fall into the transmission due to loosening. If not promptly removed, will result in the following consequences; differential gear teeth crowded or stuck; second
