Abstract

An assembling device is a device for assembling a boot and a sealing ring to an inner race of a constant velocity joint in which a fixing part of the boot is fastened to the inner race by the sealing ring and includes: a guider provided with a guide surface on an outer surface to guide the boot and the sealing ring along a longitudinal direction of the inner race; and a pusher that provides a force to move the boot and the sealing ring along the guide surface to reach a support surface of the inner race.

Claims (13)

1 . An assembling device for assembling a boot and a sealing ring to an inner race of a constant velocity joint in which a fixing part of the boot is fastened to the inner race by the sealing ring, the fixing part having a ring shape, comprising:

a guider provided with a guide surface on an outer surface to guide the boot and the sealing ring along a longitudinal direction of the inner race;

a pusher that provides a force to move the boot and the sealing ring along the guide surface to reach a support surface of the inner race; and

a supporter interposed between the boot and the sealing ring assembled to each other and configured to move along a circumference of the guide in a movement direction of the boot and the sealing ring as the pusher moves, allowing the boot and the sealing ring to be pushed,

wherein the supporter has a protrusion that is inserted between an inner surface of the fixing part and the guide surface.

2 . The assembling device of claim 1 , wherein the guide surface is an inclined guide surface formed to be inclined with respect to a movement direction of the boot and the sealing ring.

3 . The assembling device of claim 2 , wherein the inclined guide surface is formed to be inclined at an angle of 1° to 5°.

4 . The assembling device of claim 1 , wherein the protrusion has a wedge shape that becomes sharper towards a leading edge.

5 . The assembling device of claim 1 , wherein the pusher is configured to move under a load of 300 to 1500 N while pushing the boot and the sealing ring.

6 . An assembling device for assembling a boot and a sealing ring to an inner race of a constant velocity joint in which a fixing part of the boot is fastened to the inner race by the sealing ring, the assembling device comprising:

a guider provided with a guide surface on an outer surface to guide the boot and the sealing ring along a longitudinal direction of the inner race; and

a pusher that provides a force to move the boot and the sealing ring along the guide surface to reach a support surface of the inner race; and

wherein the guider comprises a first insertion space for receiving at least a portion of the inner race, and the pusher comprises a second insertion space into which at least a portion of the guider is inserted, such that the pusher is configured to move relative to the guider to push the boot and the sealing ring while the guider is fitted into the pusher.
