Patent ID: 8651465

Claim:
A method of manufacturing a bushing assembly that includes a vibration damping rubber bushing having a round cylindrical resin outer cylinder, a rigid inner cylinder, and a rubber elastic body integrally vulcanization bonded to the outer cylinder and the inner cylinder, and providing elastic linkage thereof, the bushing assembly being assembled by press fitting an outside peripheral face of the outer cylinder in an axial direction into a cylindrical metal mated component having a circular inside peripheral face, the method comprising the steps of: press fitting the vibration damping rubber bushing into the mated component with the outside peripheral face of the outer cylinder: wherein the outside peripheral face of the outer cylinder is subjected to blasting treatment with a rigid powder, which is employed as projectile material and is composed of material harder than the outer cylinder, the rigid powder being deposited in an embedded condition and retained in a section of the resin outer cylinder that is situated on the outside peripheral face and that mates with the inside peripheral face of the mated component; and assembling the outer cylinder and the mated component in a mated condition such that the rigid powder intervenes between the outside peripheral face of the outer cylinder and the inside peripheral face of the mated component, wherein a resin coating of epoxy resin is formed on the inside peripheral face of the mated component by cationic electrodeposition coating, coating, wherein the resin coating of epoxy resin is a film having a thickness of between about 10-30 μm; and the rigid powder deposited in the embedded condition and retained in the section of the resin outer cylinder is embedded into the resin coating of epoxy resin formed on the inside peripheral face of the mated component in order to increase a dislodgement force of the vibration damping rubber bushing.
