Abstract
A wobble plate in a wobble plate compressor has a bevel gear positioned at a central portion thereof. The bevel gear is provided with a centered ball seat. A second bevel gear is supported on the cylinder block and also has a centered ball seat. A bearing ball is seated in both of the ball seats so that the wobble plate nutates about the ball. At least one of the bevel gears is coated with electroless composite plating layer having a self-lubricative material, such as polytetrafluoroethylene (PTFE), dispersed therein. Consequently, the bevel gears have low frictional resistance, high hardness and improved anti-seizure characteristics.
Claims8
A method of forming a composite layer on a bevel gear rotation prevention mechanism used in a wobble plate type compressor, said met hod comprising the steps of:
- forming an inner layer on the rotation prevention mechanism by electrodeposition;
- and
- forming an outer layer on the inner layer, wherein the step of forming the outer layer comprises the steps of:
- immersing the rotation prevention mechanism having the inner layer in a solvent bath comprising nickel, phosphorous and polytetrafluoroethylene;
- rinsing the rotation prevention mechanism with an aqueous solution;
- and
- drying the rotation prevention mechanism.
A method of forming composite layer on a bevel gear rotation prevention mechanism used in a wobble plate type compressor, said method comprising the steps of:
- forming a first layer on the rotation prevention mechanism by coating the rotation prevention mechanism with a first layer of nickel by electrodeposition;
- forming a second layer on the first layer by coating the rotation prevention mechanism with a second layer of nickel by electroless application;
- and
- forming a third layer on the second layer, the step of forming the third layer comprising:
- immersing the rotation prevention mechanism having the first and second nickel layers in a solvent bath comprising nickel, phosphorous and polytetrafluoroethylene;
- rinsing the rotation prevention mechanism with an aqueous solution;
- and
- drying the rotation prevention mechanism.
