  • Patent number: 6116393
    Abstract: In an annular space between a pulley and a shaft body disposed coaxially with each other, a one-way clutch is interposed in an intermediate range in an axial direction and rolling bearings are disposed on both sides in the axial direction of the one-way clutch. A tightening distance for fitting between the one-way clutch and pulley is set to be smaller than that between the rolling bearing and pulley. Due to this structure, in a condition in which an excessive radial load acts upon the pulley, that radial load acts on not the one-way clutch but the rolling bearings on both sides thereof, so that a clutch operation of the one-way clutch can be carried out stably.

  • Patent number: 5779020
    Abstract: An assembly for rotatably mounting a shaft to a member includes a passage formed in the member within which the shaft is received, and a series of grooves formed in an internal wall which defines the passage. The grooves extend parallel to the axis of the passage and the shaft, and a pin member is received within each groove. Each pin member has a diameter greater than the depth of the groove, so that a portion of the pin member extends beyond the internal wall. The shaft is engaged by the pin members, which function to maintain the shaft out of engagement with the internal wall. The groove and pin member construction provides a bearing between the shaft and the member, without the need and space requirements of a cage typically associated with a conventional preassembled needle bearing package. The invention can be used in any application in which a shaft is to be rotatably mounted to a member, and illustratively may be used in a centrifugal clutch assembly.

  • Patent number: 5509517
    Abstract: The flying wedge clutch assembly is a speed actuated coupling device that provides low speed axial load and torque transmission and disengages for increased shaft motion at higher speeds. The flying wedge clutch assembly is a compact and lightweight design, roughly equivalent to a conventional ball bearing assembly in a typical turbopump application. Advantageously, the flying wedge clutch assembly can be used in high speed rotating machines with radial hydrostatic bearings eliminating the speed and life limitations normally attributed to rolling element bearings.

  • Patent number: 5474165
    Abstract: A declutching device, especially for a motor vehicle clutch of the pull-off type, comprises an hydraulic actuator. The latter comprises a fixed member and a movable member in piston and cylinder relationship, defining a control chamber between them, together with preloading force for biassing the movable member of the hydraulic actuator permanently towards one of its end positions with respect to the fixed member of the actuator. The supply of hydraulic fluid to the control chamber is under the control of a valve, which is for example incorporated in a boss which is part of the fixed member of the hydraulic actuator. The valve has a movable valve member which is in communication with the control chamber on one side, and which is biassed by a spring on the opposite side of the valve member.

  • Patent number: 5433305
    Abstract: An assembly includes an overrunning clutch, a rolling bearing and a casing supporting them. An overrunning clutch-supporting portion of the casing has inwardly protruding portions that inter-engage with raised portions on an outer ring of the overrunning clutch in the direction of rotation of the outer ring. As a result, a clearance is defined between the inwardly protruding portions of the overrunning clutch-supporting portion and the raised portions of the outer ring. The overrunning clutch is automatically centered to a rotation shaft when used. An elastic ring is interposed in a predetermined compressed state between the outer ring and the overrunning clutch-supporting portion. Frictional resistance is produced between the outer ring and the overrunning clutch-supporting portion preventing the overrunning clutch from becoming shaky in the casing. The overrunning clutch is pressed against the casing by a spacer to produce the same frictional resistance between the overrunning clutch and the casing.

  • Patent number: 5318162
    Abstract: A release apparatus for a pull-type friction clutch wherein the coupling between the parts on the engine and the parts on the power train of a motor vehicle is automatically deactivated in response to separation of the engine from the power train, and is automatically reestablished during reassembly of the engine with the power train. The coupling employs a detent in the form of a resilient split wire ring which is carried by the parts on the engine or by the parts on the power train, and a complementary undercut member which is carried by the parts on the power train or by the parts on the engine and form-lockingly engages the detent when the two sets of parts assume predetermined axial positions relative to each other. A releasing device is provided on one set of parts to depress the detent into a socket in response to movement of the engine and the power train away from each other to thus deactivate the coupling.
