  • Publication number: 20190136912
    Abstract: A method of setting the clearance of a tapered roller bearing assembly of the type having a housing with an access opening, and in which housing is positioned an input shaft engaging a worm or gears for driving an output gear engaging an output shaft mounted on a bearing assembly for transmitting power. The method includes the steps of first tightening a removable cover in the housing to a point in contact with the bearing assembly and having a predetermined torque value, and thereafter backing the cover away from the bearing assembly by a distance calculated by the following formula: End play setting angle in degrees=(360 degrees)×(Clearance constant)×(Desired bearing clearance in inches)/(Thread pitch in inches). This method achieves a correct clearance setting defined by the end play setting angle in degrees where the cover is rotated by the number of degrees in the end play setting angle to reduce the predetermined torque value.

  • Patent number: 6633097
    Abstract: A stator frame for an electric motor including a substantially cylindrical shaped body section having opposed ends, a cooling passageway extending through at least a portion of the body section, and at least one spacer bar. The cooling passageway includes a cooling conduit having an inlet port and an outlet port in flow communication with the cooling passageway. The spacer bar has a notched side and at least one finger extending therefrom such that the finger mechanically couples the spacer bar to the cooling conduit.

  • Patent number: 5777730
    Abstract: Methods and apparatus for automated inspection of stator cores are described. In one embodiment, a coherent light transmitter and a light detector are optically aligned so that the detector is in the path of an optical signal emitted from the light transmitter when such signal propagates substantially uninterrupted. The light transmitter and detector are also spaced from each other at a distance sufficient to allow a stator core to be moved, e.g., translated or rotated, therebetween. Output signals from the detector are processed to determine whether the core is acceptable.

  • Patent number: 5722154
    Abstract: A skew angle setting tool and method for assisting in orienting the skew pin of an apparatus having a mandrel for stacking rotor laminations for dynamoelectric machines is described. The skew pin is movable to have at least one predetermined angular orientation with respect to the axis of the mandrel. The tool includes a first member configured to be positioned in a generally coextensive relation with the mandrel and has at least one location thereon corresponding to a preselected rotor lamination stack height, and a second member disposed in predetermined relation to the location on the first member corresponding to the preselected rotor lamination stack height. The skew pin is positionable in registration with one or more locations on the second member to orient the skew pin in corresponding angular orientations with respect to the mandrel axis.
