Rotatable On Same Axis As Shiftable Guide Roll Or Pulley Patents (Class 474/107)
  • Patent number: 10509343
    Abstract: A belt driving device includes a plurality of rollers, an endless belt, a contact surface, and a non-contact surface. The rollers include a driving roller that is rotationally driven. The endless belt is stretched between the rollers such that a predetermined tension is applied to the endless belt, and the endless belt protrudes from opposite end portions of the rollers in an axis direction of each of the rollers. The contact surface is formed at a first end portion of at least one of the rollers and comes in contact with the endless belt. The first end portion is located on a meandering direction side of the endless belt. The non-contact surface is formed at each of second end portions of the rollers and doesn't come in contact with the endless belt. The second end portions are located on a side opposite to the meandering direction of the endless belt.

  • Patent number: 7806253
    Abstract: An apparatus for steering a belt includes a steering roller supporting the belt, a rotatable element and a transmission. The steering roller is rotatable about a first axis and pivotable about a second axis, the second axis being substantial perpendicular to the first axis. The rotatable element is rotatable about a third axis, the third axis being parallel to the first axis. The transmission is arranged for converting a rotational motion of the rotatable element about the third axis into a pivoting motion of the steering roller about the second axis. The rotatable element is rotatable by a frictional force between a side portion of the belt and the rotatable element. A method for steering a belt in a steering mechanism includes such an apparatus.

  • Publication number: 20080058139
    Abstract: An automated adjustment system is provided for positioning a speed reduction belt assembly to receive an elongated wood article exiting a processing machine. The speed reduction belt assembly has opposite first and second ends. The automated adjustment system includes a horizontal adjustment mechanism operable to adjust an angle of the speed reduction belt assembly in a horizontal plane. The automated adjustment system also includes a vertical adjustment mechanism operable to adjust the height of one of the first and second ends of the belt assembly relative to the other of the first and second ends of the belt assembly, thereby adjusting an inclination of the belt assembly. The automated adjustment system further includes a control unit in communication with the horizontal and vertical adjustment mechanisms for sending control signals thereto. The control signals determine the angle and inclination of the belt assembly.

  • Publication number: 20030109343
    Abstract: A drive belt stabilizer system for reducing non-longitudinal movement of a drive belt during operation. The drive belt stabilizer system includes a base, a lower member attached to the base, an upper member slidably positioned about the lower member in a vertical manner, a support stand attached to the upper member, a roller rotatably positioned within the support stand, a compression spring positioned within the lower member and the upper member for applying an expanding force relative thereto, and a securing shaft extending though the base and secured to the support stand for limiting the upward movement of the upper member. The roller is positioned beneath the return portion of a drive belt to be supported. A threaded nut is adjusted upon the securing shaft for adjusting the maximum height of the roller with respect to the drive belt.

  • Patent number: 6409619
    Abstract: An arrangement in connection with a belt drive device having two counter-rotating continuous belts operated by drive rollers traveling around stretching rollers, whereby the belts are urged towards one another by press rolls to draw a cable between the belts. Adjustment of the stretching rollers is provided by an adjustment mechanism that effects the axle with which the stretching rollers are associated.

  • Patent number: 5583766
    Abstract: A control system is provided for a vehicle regulating engine speed during shifts so as to reduce driveline torque and shift shock. The control system includes separate microprocessor based engine and transmission controllers which communicate via a data link. When a shift is initiated, the transmission controller delays a first period of time CTSDELAY sufficient for the transmission to disengage the old gear ratio and then produces a CTSSPEED signal. The transmission controller continues to produce the CTSSPEED signal for a second period of time CTSDUR which corresponds to the time required for the transmission to engage the new gear ratio. The engine controller receives the desired engine speed signal and regulates engine speed into correspondence with the desired speed. During upshifts, the CTSSPEED signal is set to a speed which is a predetermined amount above the synchronization speed of the new gear for an upshift.

  • Patent number: 5316524
    Abstract: An apparatus for controlling the lateral alignment of a belt arranged to move in a predetermined path includes a first roll arranged to support a portion of the belt passing thereover. The first roll has first and second ends. A first centering assembly for the belt is located adjacent the first roll. The first centering assembly includes a first rotating member located adjacent a first end of the first roll and a second rotating member located adjacent a second end of the first roll. The first and second rotating members urge the belt to an equilibrium position on the first roll. In one embodiment, the first and second rotating members are rollers which may either be tapered or crowned. In a second embodiment, the rotating members are driven rollers which rotate towards each other. In a third embodiment, the two rotating members are endless tracking belts which rotate towards each other.

  • Patent number: 5181888
    Abstract: A belt driving system having at least one roller for adjusting creep within a plurality of rollers. Creep detecting means provided at one end of the creep adjusting roller is rotated by torque of a flat belt in contact with the creep detecting means. Biasing means for biasing the flat belt toward the creep detecting means and roller-end displacing means for converting the torque of the creep detecting means to displacement of the end of the creep adjusting roller toward a predetermined direction so that the flat belt is moved to the direction contrary to the creep caused by the biasing means are provided. When the flat belt creeps, the creep contrary to the original creep is caused by the roller-end displacing means, and thus the original creep is compensated. Consequently, stable running of the flat belt is obtained and clear pictures of the electrophotographic machine can be also obtained.

  • Patent number: 5078655
    Abstract: A method for adjusting the tension of a drive belt wherein a tensioning device is pretensioned, e.g., after manufacturing at the plant, with a force corresponding to the force desired for subsequent operation. At this position, calibration markings are formed which can be checked during subsequent adjustments. After being mounted, the drive belt is tensioned until the markings line up.

  • Patent number: 4929219
    Abstract: A belt driven system (1) employs a dynamoelectric machine (11) to rotate a pulley (7) on which is positioned a drive belt (13). An improvement is a belt locator (19) for locating the belt on the pulley. The locator is effective to properly locate the belt on the pulley if it is initially mis-installed with respect to the pulley, and maintains the belt position if the belt begins to slip off the pulley during operation of the system.
