Description
Technical Field
The utility model belongs to the technical field of car research and development, maintenance, it is specifically a back wheel hub bearing assembly and disassembly tools.
Background
In the running process of an automobile, a rear hub bearing bears axial load and radial load, and the rear hub bearing is a quick-wear part and a safety part in automobile parts. At present, a sledge hammer, a crowbar and the like are mostly used for mounting and dismounting a rear hub bearing. Therefore, the labor intensity of assembling and disassembling the hub bearing is high, and the hub bearing is easy to damage and the operators are injured. The press machine can be used for press mounting of the hub bearing, but some repair shops with small scale do not have press machine equipment, and when the hub shaft bench test is carried out, the press mounting of the rear hub bearing is inconvenient due to the influence of the test fixture. The pulling claw of the existing shaft pulling device can not contact the inner ring of the hub bearing, and the inner ring is still left on the hub shaft after being pulled out, and a flat shovel is needed to knock down the inner ring.
Disclosure of Invention
An object of the utility model is to provide a rear wheel hub bearing assembly and disassembly tools. The problem of above-mentioned rear wheel hub bearing exist at the dismouting in-process is solved.
The technical scheme of the utility model as follows:
a rear hub bearing dismounting tool is characterized by comprising a connecting rod, a pressing pull sleeve, a supporting plate and a pull claw, wherein the lower end of the connecting rod is matched and installed with a hub shaft of a rear hub bearing, an external thread rod is arranged at the upper end of the connecting rod, the lower end of the pressing pull sleeve is matched and installed with the upper end of the connecting rod, the supporting plate is sleeved at the upper end of the pressing pull sleeve, one end of the pull claw is provided with a hole matched with the supporting plate, the other end of the pull claw is an arc-shaped circular truncated cone, and the pull claw is sleeved at the left end and the right end of the supporting plate.
Furthermore, the lower end of the connecting rod is provided with an internal thread hole which can be matched with the external thread of the hub shaft of the rear hub bearing.
Furthermore, the lower end of the pressing and pulling sleeve is a cylinder, the cylinder is provided with internal threads, the upper end of the pressing and pulling sleeve is a cylinder and a nut matched with the cylinder, the supporting plate is sleeved on the cylinder at the upper end of the pressing and pulling sleeve, and the cylinder and the nut are installed together in a threaded fit mode.
