Patent number: 6071206Abstract: A two speed pulley assembly comprised of a sheave, a brake member, an output member, and a brake. The sheave receives a rotational input and also includes a series of carrier arms which cooperate to define a circle which is coaxially with the sheave. Rollers are rotatably supported on said carrier arms. A braking member is rotatably supported relative to said sheave and includes portions defining a first raceway in contact with the rollers. An output sleeve is also rotationally supported relative to the sheave. The output sleeve includes portions defining a second raceway in contact with the rollers. The brake inhibits rotation of the braking member when engaged while permitting rotation thereof when disengaged. Mounted between the sheave and the output sleeve is a one-way clutch bearing. The clutch bearing engages when rotation of the sheave attempts to or begins to overrun rotation of the sleeve.Type: GrantFiled: May 14, 1998Date of Patent: June 6, 2000Assignee: NTN CorporationInventors: Russell E.

Patent number: 5927456Abstract: A clutch assembly having driving and driven members with concentric cylindrical surfaces and which are independently rotatable about a common axis. A plurality of recesses are formed in the cylindrical surface of the driving member. The recesses include ramp surfaces which extend to the cylindrical surface. Roller elements are positioned in each of the recesses and a retainer, which is also independently rotatable about the axis, circumferentially interconnects the roller elements together. The retainer causes the rollers to move substantially in unison with one another and a biasing member individually biases each roller element into its respective recesses. During relative acceleration of the driving member relative to the driven member, the roller elements move along and up the ramp surfaces to a position where they become wedged between the driving and driven members. When wedged, torque can be transferred through the clutch assembly.Type: GrantFiled: November 1, 1996Date of Patent: July 27, 1999Assignee: NTN CorporationInventors: Russell E. Monahan, Jonathan M.

Patent number: 5850141Abstract: An annular wheel speed sensor having an efficient magnetic configuration to provide a high level of electrical output even at relatively low wheel speeds. The sensor comprises a magnetic tone ring having both axial and radial magnetic fields and a stator configured to read both the axial and radial magnetic fields as the tone ring rotates. The sensor is configured to minimize the effects of variation in the axial air gap between the tone ring and stator to provide an accurate and reliable wheel speed signal. The wheel speed sensor incorporates many of the bearing components to provide a compact and efficient hub and bearing assembly. Moreover, the construction of the hub and bearing of the invention provides a sealed environment for the speed sensor, isolating it from environmental factors.Type: GrantFiled: June 13, 1997Date of Patent: December 15, 1998Assignee: NTN CorporationInventor: Jonathan M.

Patent number: 5827143Abstract: A variable speed drive device for mounting to a rotatable shaft and being driven by first and second belts. The device includes a first pulley of a first diameter and a second pulley of a second diameter, each engaging one of the belts. The first pulley mounts directly to the shaft via a mounting hub extending laterally therefrom. The second pulley is positioned radially outward of the hub and a bearing is located between the two. Also located between the two is a clutch mechanism that engages when the second pulley tries to rotates faster than the first pulley. In this manner, the first pulley drives the shaft at a first speed when the first pulley is rotating faster than the second pulley and the second pulley drives the shaft at a second speed when the second pulley is trying to rotate faster than the first pulley.Type: GrantFiled: June 4, 1997Date of Patent: October 27, 1998Assignee: NTN CorporationInventors: Russell E.

Patent number: 5602946Abstract: An improved fiber optic sensor system and integrated sensor bearing assembly for detecting movement or position of a rotating wheel bearing having a multi-pole tone ring which produces an alternating magnetic field indicative of movement and position of the rotating member. A magneto-optical material, such as a bismuth garnet iron (B.I.G.) crystal, having discrete magnetic domains is positioned in the vicinity of the tone ring so that the domains align themselves to the magnetic field generated by the tone ring. A single fiber optic cable, preferably single mode fiber, carries light generated by a source of light to the B.I.G. crystal. The light passes through the B.I.G. crystal and is refracted at domain boundaries in the crystal. The intensity of the refracted light is indicative of the amount of alignment of the domains and therefore the strength of the magnetic field.Type: GrantFiled: December 22, 1995Date of Patent: February 11, 1997Assignee: NTN Technical Center (USA)Inventors: Lynn R. Veeser, Patrick J. Rodriguez, Peter R. Forman, Russell E. Monahan, Jonathan M. Adler

Patent number: 5381090Abstract: A bearing assembly incorporating a speed and/or temperature sensor particularly adapted for motor vehicle wheel applications. The sensor incorporates a magnetized tone ring defining a radial or cylindrical face which interacts with an annular transducer. The transducer has a plurality of teeth facing the magnetized tone ring with separate first and second rows of teeth extending from the transducer frame. The first set of teeth engage one area of the tone ring defining one magnetic pole whereas the second series of teeth interact with regions of the tone ring defining the opposite magnetic pole. Relative rotation between the transducer and tone ring induces an alternating magnetic field through the transducer case which induces an alternating voltage in the winding coil. The transducer is efficiently packaged within the enclosed cavity of a bearing assembly. This invention further contemplates a means to allow transducer temperature to be evaluated by monitoring the DC resistance of the transducer winding.Type: GrantFiled: January 31, 1994Date of Patent: January 10, 1995Assignee: NTN Technical CenterInventors: Jonathan M.
