Claims
- 1. A process for electrodepositing a metallic layer on half sliding bearings in an electroplating tank comprising,
- introducing the half sliding bearings into the electroplating tank separately from a position above the electroplating tank,
- passing the half sliding bearings through the electroplating tank wherein the half sliding bearings are moved step-wise downwards by means of a first vertical conveyor, passed on from the first vertical conveyor to a horizontal conveyor which passes the half sliding bearings to a second vertical conveyor, and conveying the half sliding bearings upwards by means of the second vertical conveyor, and
- removing the half sliding bearings from the electroplating tank,
- wherein the electrodeposition of the metallic layer is carried out while the half sliding bearings are moved vertically in at least one of the two vertical conveyors on a sliding plate on which the half sliding bearings are arranged in mutual contact with one another and connected to a cathode.
- 2. The process according to claim 1 further comprising magnetically holding said half sliding bearings on the sliding plate of said at least one vertical conveyor.
- 3. The process according to claim 1 further comprising moving said half sliding bearings horizontally on a sliding plate in said horizontal conveyor.
- 4. The process according to claim 3 wherein said half sliding bearings are held magnetically on the sliding plate of the horizontal conveyor.
- 5. The process according to claim 1 further comprising,
- immersing the half sliding bearings successively in a recovery tank after removal from the electroplating tank for recovering the electroplating solution carried off by the half sliding bearings from the electroplating tank, and
- rinsing the half sliding bearings taken out of the recovery tank successively in a water rinsing tank.
- 6. The process according to claim 1 further comprising,
- moving the electroplating solution adjacent to the surfaces of half sliding bearings onto which the metallic layer is being electrodeposited.
- 7. The process according to claim 6, wherein the electroplating solution is moved by jetting it from an opening of a tube placed opposite to the half sliding bearings.
- 8. The process according to claim 7, wherein the electroplating solution is jetted at a pressure of about 0.2 kgf/cm.sup.2 from the opening of the tube.
- 9. The process according to claim 1 wherein said half sliding bearings are initially coated with a nickel layer in said electroplating tank followed by a lead alloy layer in a second electroplating tank.
- 10. The process according to claim 1 wherein the half sliding bearings are passed through the electroplating tank at a speed of 0.2 m/min. to 1 m/min.
- 11. A process for electrodepositing a metallic layer on a series of sliding bearings, in an electroplating tank, comprising
- providing an electroplating tank containing a first vertical conveyor for conveying a series of sliding bearings in a step-wise downward direction, a horizontal conveyor for receiving said series of sliding bearings from said first vertical conveyor and for passing said sliding bearings in a horizontal direction, and a second vertical conveyor for receiving said series of sliding bearings from said horizontal conveyor and conveying said series of sliding bearings in an upward direction;
- introducing said series of sliding bearings into said electroplating tank separately from a position above the electroplating tank;
- passing each of the sliding bearings in said series through said electroplating tank first step-wise downwardly by means of said first vertical conveyor, then horizontally by means of said horizontal conveyor, and then upwardly by means of said second vertical conveyor; and wherein the sliding bearings are placed against a sliding plate and in mutual contact with one another and are connected to a cathode while carrying said bearings in vertical movement on at least one of said two vertical conveyors;
- electrodepositing a metallic layer on said sliding bearings during said vertical movement; and
- removing said sliding bearings from said electroplating tank.
