Description

Differential bearing locking spiral ring handling tool

Technical Field

The utility model belongs to the technical field of mechanical maintenance tools, and particularly relates to a differential bearing locking spiral ring assembling and disassembling tool.

Background

In a construction vehicle, in which a differential is used to realize turning of the vehicle, left and right wheels or front and rear wheels are moved at different rotational speeds so as to keep the vehicle running smoothly, the differential structure is mainly composed of a planetary gear, a side gear, a planetary gear shaft, a differential case, rolling bearings and various auxiliary structural members, and in which the rolling bearings are used to support the rotation of the planetary gear, the side gear, the planetary gear shaft or the differential case, the assembly positions of the rolling bearings are very precise, in the prior art, when the rolling bearings are turned into the differential, in order to make the rolling bearings tightly assembled, it is often necessary to provide corresponding locking mechanisms for locking or locking the rolling bearings, for example, the publication No.: patent literature of CN208546503U discloses a differential bearing locking mechanism, which is composed of an adjusting ring, a locking plate and a combination bolt; the two tapered roller bearings of the differential mechanism are arranged in two semicircular holes of the speed reducer shell, and the semicircular holes of the two differential mechanism bearing covers are matched with the two tapered roller bearings; the adjusting ring is fixed with a threaded hole formed by the speed reducer shell and the differential bearing cover, and the speed reducer gear achieves the standard gear side clearance; one end of the locking plate with a round hole is arranged in a groove of the differential bearing cover, and the other end of the locking plate is arranged in a distribution groove of the adjusting ring; the combined bolt passes through the round holes of the differential bearing cover and the locking plate and is in threaded connection with the threaded hole of the differential bearing cover. By adopting the technical scheme of the patent document, the locking plate and the differential bearing cover are connected by using one combined bolt, the number of bolts is reduced, the material cost of the locking plate is reduced, the weight of the locking plate is reduced, and the assembly efficiency of the locking plate is improved, however, because the rolling bearing is used for supporting the planetary gear, the side gear and the planetary gear shaft or the differential case to rotate, the rolling bearing always needs to bear more motion load, therefore, the rolling bearing belongs to a vulnerable part, when the rolling bearing is damaged, the corresponding locking ring is firstly disassembled when the rolling bearing is replaced, as shown in fig. 1 and 2, the locking spiral ring in a certain type of differential mechanism comprises a spiral ring body (5), external threads are arranged on the peripheral surface of the spiral ring body (5), a plurality of bosses (6) are further arranged on the surface of the spiral ring body (5), after the locking spiral ring is assembled into the differential mechanism, the lower end face of the spiral ring body (5) seals and compresses the rolling bearing, and a user can apply an action moment to the surface bosses (6) of the rolling bearing, so that the locking spiral ring is screwed or loosened, however, because the locking shape is smaller, the corresponding bosses (6) have a small gap, and the loading and unloading effects on the spiral ring (6) are not convenient when a maintenance person loads the spiral ring, and unloads the spiral ring (6) conveniently when loading and unloads.

Disclosure of Invention

In order to solve the technical problems, the utility model provides a differential bearing locking spiral ring assembling and disassembling tool.

The utility model is realized by the following technical scheme.

The utility model provides a differential bearing locking spiral ring loading and unloading tool which comprises a tray and a plurality of force guide tables, wherein a regular polygon containing hole is formed in the centroid of the tray, one end of each force guide table is fixedly connected with the tray, the other end of each force guide table extends out of the side face of the tray, and the force guide tables are distributed around the centroid of the tray according to a circumferential array.
