  • Patent number: 11261942
    Abstract: A speed reducer capable of reliably reducing and changing speed while suppressing heat generation and abrasion includes: a plurality of gears rotatably supported on an output shaft; a shifter engageable with an engagement gear selected from the plurality of gears to couple the engagement gear to the output shaft; and a plurality of bushes disposed in an annular groove formed in the shifter to move the shifter to the engagement gear and thereby engage the shifter with the engagement gear; and a bush support supporting the plurality of bushes so as to allow them to swing individually.
    Type: Grant

  • Patent number: 10871219
    Abstract: Provided is a speed-switchable reduction gear including: an input shaft; an output shaft; a plurality of output-side geared-wheels mounted on the output shaft; a shifter for selecting the output-side geared-wheel to be used; a shifter-side first bearing and a non-shifter-side second bearing provided to each the output-side geared-wheel; and a plurality of dividing walls each provided in each cell between the first and second bearings. The output shaft has an axial lubricating-oil flow path and a plurality of supply flow paths. Each dividing wall divides each cell into a first cell adjacent to the first bearing and a second cell adjacent to the second bearing and allows lubricating oil to be supplied from the supply flow paths into the first and second cells so as to make pressure of lubricating oil in the first cell higher than that in the second cell.

  • Publication number: 20070192015
    Abstract: A torque estimation error, which is an error between an estimated value and an actual value of the engine torque, is detected at first. Then, an error of a characteristic for engine frictional loss is learned based on the torque estimation error which is detected when ignition timing is around a most appropriate timing. An error of a characteristic for an ignition timing efficiency, which represents a relation between the ignition timing and an engine torque change, is further detected, based on the torque estimation error which is detected when ignition timing is delayed from the most appropriate timing. And the estimated value of the engine torque is corrected based on learning values for the errors of the engine frictional loss and the ignition timing efficiency.

  • Patent number: 4988049
    Abstract: An air capacity controlling method for a centralized blower system wherein a common suction air duct is connected to a plurality of winders such that suction air for operation may act upon the winders through the duct, and a preset number of suction blowers having a total air capacity corresponding to a total air quantity necessitated by the winders are connected in a parallel relationship, is constituted such that it is detected from a pressure of air within the duct that the total air quantity necessitated by the winders has varied, and the air capacity of the suction blowers is adjusted in accordance with such a detection value.

  • Patent number: 4660369
    Abstract: A bobbin transporting system in which a winder area and a spinning frame area having a plurality of spinning frames are connected to each other by means of a spinning bobbin transporting line and an empty bobbin transporting line. Transport bands for spinning bobbins are located along opposite sides of the spinning frame and are circulated in integral relationship so that spinning bobbins are delivered at the same time from the transport bands to the spinning bobbin transporting line and supplied to the winder.
