Sliding spline pair anti-disengaging structure

The invention relates to a sliding spline pair anti-disengaging structure. The structure is composed of a spline pair body. The spline pair body is formed through sequential cup joint of a spline shaft fork, a sealing casing pipe, a framework oil seal and a spline sleeve, and an anti-disengaging component is arranged on the spline pair body. The sliding spline pair anti-disengaging structure has the beneficial effects that compared with the prior art, according to the innovation points of the sliding spline pair anti-disengaging structure, firstly, manufacturing of a ribbon base and a ribbon for fixing a spline pair is simple, and cost is low; and secondly, spline pair bundling is easy, dismounting is easy, repeated bundling and dismounting can be conducted, and the appearance of paint ofa transmission shaft is not influenced. The ribbon base used for fixing the spline pair can be directly arranged on the transmission shaft in a projection welding manner through an existing dynamic balance machine, additional
