Patent number: 8057196Abstract: A compressor assembly includes a compressor coupled to a motor via a belt drive. The belt drive provides a speed reduction between the motor and compressor and causes the compressor shaft to rotate in the direction opposite that of the motor shaft. The relative values of the mass moments of inertia about the axes of rotation of the rotating motor and compressor shafts are engineered to be inversely proportional to the relative shaft speeds, allowing the mass moments of inertia to be balanced to at least substantially eliminate torsional vibration.Type: GrantFiled: May 21, 2003Date of Patent: November 15, 2011Assignee: Black & Decker Inc.Inventor: Mark W. Wood

Patent number: 8011899Abstract: A compact water pump assembly has a shaft extending from a first end to a second end. An annular groove is located on the shaft. A housing member is located about the shaft and intermediate the first and second ends. An impeller is coupled to the second end of the shaft. A plurality of bearing members are arranged in a single-row within the groove. The bearing members rotatably support the shaft in the housing. In addition, each bearing member includes a radial centerline. A pulley is coupled to the first end of the shaft. The pulley is capable of engaging a drive belt such that the centerline of the belt driving surface is in substantial alignment with the bearing centerlines.Type: GrantFiled: May 31, 2007Date of Patent: September 6, 2011Assignee: Metaldyne, LLCInventor: James A.

Patent number: 7927081Abstract: A pump station comprising includes a motor and pump arrangement, a tank for holding a liquid; and a frame for supporting the tank generally above the motor and pump arrangement. The motor and pump arrangement includes a motor having a drive shaft rotatable about a first longitudinal axis and a pump having a drive shaft rotatable about a second longitudinal axis oriented parallel to the first longitudinal axis. A drive mechanism interconnects the drive shaft of the motor and the drive shaft of the pump. A mounting assembly is provided and includes a lower portion mounted to a portion of one of the motor and the pump; and an upper portion to which the other of the motor and the pump is mounted. The lower portion and the upper portion are configured and selectively movable in such a manner that the drive shaft of the motor and the drive shaft of the pump, during translation movement relative to each other, are constrained from rotational movement relative to each other.Type: GrantFiled: March 10, 2006Date of Patent: April 19, 2011Assignee: MacNeil Wash Systems LimitedInventor: Daniel J.
