Description

Bearing seal cover hydraulic detachment unloads the goods from the airplane

The utility model relates to the bearing removal machine, and particularly bearing seal cover hydraulic detachment unloads the goods from the airplane.

There is seal closure 45 at bearing 3 two ends of adorning on the lorry axle, seal closure is a thin-walled stamping parts, its relies on projection garden ring 48 on stub end outer wall to be pressed into the groove of outer race 44 inner faces and strong bonded, and need be taken seal closure and outer race apart when bearing overhaul.Existing method for dismounting has two kinds, and the one, stretch in the seal closure under the seal closure sled with crowbar; Other pulls out son with three-jaw to stretch in the seal closure, and seal closure is extracted.Though first method is simple, but very easily damage the rubber seal and the thin-walled seal closure of seal closure, cause seal closure to scrap, seal closure also takes place in the operating process of being everlasting second method damages, because the bearing arrangement size is limit, makes three-jaw be compelled to do very for a short time and overhang bigger simultaneously, so poor reliability, fault is many, and these two kinds of methods all can not make seal closure reuse, and make the cost height that repairs.

The purpose of this utility model is to overcome the prior art weak point and designs a kind of labor strength that alleviates, and the thin-walled seal closure is not damaged in unloading process, and is indeformable, improve repeat usage, and the bearing seal cover hydraulic detachment of easy operating unloads the goods from the airplane.
