  • Patent number: 8512185
    Abstract: A switchable drive pulley system that allows driving engagement or disengagement of a pulley from the shaft of an accessory drive. The pulley is mounted to the shaft by a bearing having an inner ring that rotates with the shaft and an outer ring that rotates with the pulley. A friction disk is arranged adjacent to the bearing inner and outer ring. When axial pressure is applied to the friction disk, relative motion between the inner and outer bearing rings is stopped, allowing transfer of torque from the pulley to the shaft to drive the accessory drive, with the pulley and shaft rotating at the same speed. When pressure is removed from the friction disk, the pulley and the outer bearing ring can spin independently of the inner ring and shaft. The shaft can therefore remain stationary while the pulley continues to turn driven by the accessory belt drive.

  • Patent number: 7563187
    Abstract: In a drive belt system, an idler pulley 6 is formed by an auto belt alignment pulley. For example, a pulley body 60 is rotatably carried on a hollow cylindrical shaft member 62, a support rod 63 is inserted in the shaft member 62, and the pulley body 60 and the shaft member 62 are connected to each other via a pin 64 (pivot axis C2) for angular movement about the pin 64. The pin 64 is inclined orthogonally to the shaft member 62 and forward in the direction of rotation of the pulley body 60 with respect to the direction of a radial shaft load L. With this configuration, when a flat belt 8 deviates to one side, the pulley body 60 inclines to create a level difference in the direction of the radial shaft load L and angularly moves orthogonally to the flat belt 8, thereby correcting the deviation of the flat belt 8. To fulfill the auto belt alignment function, belt span lengths Si and So between the idler pulley 6 and both the adjacent pulleys 3 and 4 are each set larger than the width of the flat belt 8.

  • Patent number: 7419448
    Abstract: A hollow cylindrical pulley body 5 is carried rotatably by a hollow cylindrical shaft member 11. A support rod 8 is inserted in the shaft member 11 to support the shaft member 11 for rocking motion about a pivot axis C2 orthogonal to the shaft member 11. The pivot axis C2 is inclined backward in the direction of belt travel with respect to the direction of load on the shaft member 11. With this configuration, when the drive belt 3 deviates to one side, the pulley body 5 is immediately angularly moved so that it is inclined with a level difference with respect to the direction of load on the shaft member 11 and is positioned obliquely relative to the drive belt 3, thereby producing a force of returning the drive belt 3 to its normal position.

    Abstract: A centrifugal blower is provided which incorporates a self-contained air cooling system. The blower includes a drive assembly connected to a drive motor and disposed within a housing having inlet and outlet apertures. A centrifugal compressor is connected to the drive assembly and disposed exteriorly to the housing adjacent to the outlet apertures. Rotation of a drive pulley, including a fan, by the drive motor causes air to enter the housing through the inlet apertures, flow over components of the drive assembly, and exit through the outlet apertures. A spindle assembly having a rigid bearing arrangement is also provided. One or more bearing elements are disposed at opposite ends of a spacer and between a shaft and housing of the spindle assembly. Such rigid pre-loaded bearing arrangement eliminates “unloading” concerns, and allows load sharing between bearing elements.

  • Patent number: 7311625
    Abstract: A screw engagement portion between a pulley and a shaft is provided with a thread in a direction to increase the tightening torque when the pulley is driven. A breakable part broken by the axial tension produced when the tightening torque acting on the screw engagement portion is above a predetermined value, is also provided. The stress to break the breakable part is mainly a tensile stress. The tensile stress is substantially uniformly distributed in a cross section and, hence, the stress distribution of the breakable part can be relatively precisely predicted and analyzed. Consequently, the necessity of determining aspects of the breakable part, such as dimension, material, and the like, by trial and error is reduced. The breakable part can be broken without being subject to fatigue fracture.
