  • Patent number: 8303423
    Abstract: A power transmission interconnects a drive body and a driven body by a coupling member, transmits torque of the drive body to the driven body, and interrupts the torque when a drive load of the driven body exceeds a predetermined value. The coupling member has, as separate sections in the coupling member, both of a positive torque transmission section and a negative torque transmission section. The positive torque transmission section holds torque in the forward rotational direction and, when a drive load of the driven body exceeds the predetermined value, interrupts transmission of torque from the drive body by its own fracture. The negative torque transmission section holds torque in the reverse rotational direction. Even if there is a torque fluctuation on the drive body, its influence can be suppressed as little as possible, and interruption of torque can be performed properly at a target interruption torque value.

  • Patent number: 5728019
    Abstract: A drive system, especially a belt drive for a multi-axial vehicle running gear, has a drive drum about which the belt is looped and provided with a ring with entrainers which engage teeth on the belt when there is slip between the belt and the drum. Limited rotation of the ring relative to the drum may be effected by elliptical spring elements coupling the ring and the drum or by clutches on the drum which frequently lock the ring to the drum so as to effect control engagement of the entrainers with the belt teeth and positive drive of the belt by the drum.

  • Patent number: 5591093
    Abstract: A lightweight damper pulley is provided which can be produced in a simple manner. The damper pulley includes a central portion, including a cylindrical boss portion to be fixed onto a rotary shaft, a main portion extending radially outwardly from the larger diameter part of the cylindrical boss portion and a central flange bent to extend horizontally from an outer periphery of the main portion. This forms a substantially U-shaped cross-sectional profile. The pulley also includes a belt retaining portion made of metal plate that also has a substantially U-shaped cross section profile. This space is determined between an outer belt supporting wall, an inner belt portion flange and a radially extending connecting wall. The pulley is constructed by reversing the two U-shaped profiles or dissecting the belt retaining flange to the interior of the central flange, with an elastic, damping ring forcefit therebetween. The belt retaining flange can also be moved radially outwardly to compress the elastic.

  • Patent number: 5575728
    Abstract: A drive assembly for rotating a shaft of a pulley driven device. The drive assembly includes a hub in the form of an annular body of ferrous metal having a groove in an external periphery thereof. A belt driven pulley is provided in the form of ferrous sheet metal and has a web portion. A structural connection is defined between the hub and the pulley web portion such that the hub is in fixed, abutted relation with the pulley web portion. The hub and the pulley web portion have a bore therethrough defining a single, machined annular surface. The annular surface is constructed and arranged to engage a periphery of the shaft in an interference-fitted manner so as to maintain torque transfer to the shaft in the event of failure of the structural connection. The groove is constructed and arranged to be operatively engaged by a pulling tool for removing the annular surface from engagement with the shaft.

  • Patent number: 5421788
    Abstract: An idler pulley and bearing assembly for handling the drive belt of a front end accessory drive system of an internal combustion engine includes a bearing having an outer race and an inner race with an aperture for extending therethrough, and a mounting structure for securing the outer race of the bearing such that the outer race will not rotate. A pulley mounted upon a shaft extending through the aperture in the inner bearing is attached to the inner race such that the shaft pulley and inner race rotate at the same speed. This construction greatly reduces the rotational speed of the anti-friction elements within the bearing and preserves the bearing's lubrication, so as to prolong the life of the bearing, while reducing noise generated by the bearing.

  • Patent number: 5413535
    Abstract: Vibrations of the camshaft or crankshaft of a combustion engine are damped between a composite pulley which receives torque from the engine and one or more sheaves which are driven by an endless flexible member and serve to transmit torque to a pump, a blower, a compressor, a steering wheel mechanism and/or an alternator. The endless flexible member exhibits a certain amount of elasticity and the composite pulley comprises a rotary input device which is driven by the engine and a hollow rotary wheel which has a circular radially inner portion in rolling contact with the periphery of the input device. The outer diameter of the input device is smaller than the inner diameter of the wheel. The latter performs pendulum movements in response to changes in the length of the elastic flexible member.
