  • Supporting mechanism for a wobble plate and method of making same
    Patent number: 5789038
    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.

  • Wobble plate type refrigerant compressor having a ball-and-socket joint lubricating mechanism
    Patent number: 5131319
    Abstract: A wobble plate type refrigerant compressor having a lubricating mechanism provided at a ball-and-socket joint between a wobble plate and a piston rod is disclosed. A wobble plate type refrigerant compressor includes a compressor housing having a cylinder block. A plurality of cylinders are formed around the periphery of the cylinder block and a piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism. A crankcase is formed between the cylinder block and a front end plate of the compressor housing. The drive mechanism includes a drive shaft, a rotor fixed to the drive shaft and a wobble plate disposed on an inclined surface of the rotor. The piston rod connects the wobble plate to the piston. A ball at one end of the rod is received in a socket formed at the wobble plate to form a ball-and-socket joint. A hole is formed at the wobble plate to link one end surface of the wobble plate to the friction surface of the ball-and-socket joint.
