Patent number: 8058868Abstract: A system for determining an absolute position of a motor. The system includes first and second multi-polar magnetic rings, first and second processing units, and at least one external sensor. The first multi-polar magnetic ring is concentrically positioned around the motor, and has a plurality of pole pairs. The second multi-polar magnetic ring is concentrically positioned around the first multi-polar magnetic ring, and has at least one pole pair. The first processing unit is positioned near the first multi-polar magnetic ring to determine an angular position over one of the pole pairs of the first multi-polar magnetic ring. The sensor is positioned external to the processing unit and over the second multi-polar magnetic ring to indicate a state of the pole pair of the second multi-polar magnetic ring. The second processing unit generates an absolute position of the motor based on the angular position and the state.Type: GrantFiled: April 10, 2007Date of Patent: November 15, 2011Assignee: Timken US CorporationInventors: Alfred John Santos, Mark E. LaCroix, Wayne V. Denny

Patent number: 7579827Abstract: A device for sensing the input shaft speed of an automotive automatic transmission that is driven by the engine through the fluid coupling of a torque converter. The speed sensor device includes circumferentially spaced markings about the transmission input shaft and a speed sensor that is placed at close proximity to the circumferentially spaced markings through a hole in the torque converter stator shaft. An electronic control unit (ECU) analyzes the sensor output signal and in the case of an active speed sensor it also functions as its power source. During vehicle operation, the transmission input shaft rotates the target wheel in front of the speed sensor causing modulation of its output signal. The electronic control unit analyzes the signal modulation and calculates the input shaft rotational speed. A variety of sensor/target-wheel options and sensor mounting techniques could be used depending on the application constraints.Type: GrantFiled: September 21, 2007Date of Patent: August 25, 2009Assignee: Timken US CorporationInventors: James J. Burns, Wayne V. Denny, Mark A. Joki, Mark E. LaCroix, Brian Thomas Odegard, Alfred John Santos, Orestes J. Varonis

Patent number: 7093505Abstract: A speed sensor (B, C) produces a signal that reflects the angular velocity of a shaft (4) which rotates in a case (2) having a mounting surface (10), beyond which the shaft projects to provide a target (6), and threaded holes (12) which open out of the mounting surface. The speed sensor includes a housing (20) and a sensing element (22) which is embedded in the housing. The housing, which is formed from a deformable material, has slots (44, 60) which align with the threaded holes in the case, and receive screws (24, 66) which thread into the holes to secure the speed sensor to the case. The speed sensor is positioned such that the proper air gap exists between its sensing element and the target. The screws, which extend through the slots, produce indentations (56, 74) in the deformable material of the housing, and these indentations receive the screws, so that the position of the sensor is fixed. Thus, the sensor, if removed, may be reinstalled in the same location.Type: GrantFiled: July 16, 2003Date of Patent: August 22, 2006Assignee: The Timken CompanyInventors: Wayne V. Denny, Richard Smith, Kevin Rehfus

Publication number: 20040017190Abstract: An apparatus and process for determining the absolute angular position of a rotating component. One or more linear position sensors, such as, for example, a Hall-Effect sensor, are placed near a degrading surface of a shaft or other rotating component. The rotation of the shaft varies the air gap between the sensor and the degrading surface thereby generating signals than can be processed to determine various operating parameters of the rotating shaft or component such as the absolute angular position of the rotating shaft, the rotation speed of the shaft, and the acceleration of the rotating shaft.Type: ApplicationFiled: July 17, 2003Publication date: January 29, 2004Inventors: Graham F.

Patent number: 6532666Abstract: A hub assembly includes a hub having a flange and a spindle projected from the flange, a housing located around the hub spindle, and an antifriction bearing between the housing and the spindle. The bearing includes an inner race which the spindle initially accommodates in that the spindle has a deformable end over which the inner race is passed. Thereafter, the deformable end is upset into a formed end in a rotary forming procedure that involves forcing the deformable end and a forming tool together while the spindle and tool rotate. The formed end should bear snugly against a back face on the inner race and capture the inner race on the spindle. In the forming procedure the spindle and forming tool are forced together initially in a coarse feed which provides the formed end that bears against the back face of the inner race, then at a fine feed, and finally at a dwell.Type: GrantFiled: November 29, 2001Date of Patent: March 18, 2003Assignee: The Timken CompanyInventors: Wayne V.
