    摘要： Provided is a reduction gear comprising a bearing state detection device capable of detecting the state of a rolling bearing that rotates integrally with an output shaft and an output gear during power transmission. The bearing state detection device comprises: a plurality of displacement sensors (1, 2, 11, 12), which are disposed in mutually differing positions at the sides of output gears (26, 27) having helical threads (35a, 37a) formed in the outer peripheral surfaces, and which detect the amount of axial displacement of the side surfaces of the output gears; and a processing unit (5), which determines the amount of tilt of the gears (26, 27) on the basis of the amount of displacement detected by the plurality of displacement sensors (1, 2, 11, 12) during rotation of the output gears (26, 27) when the output gears are linked to an output shaft (25) by a linking mechanism (32).

    摘要： A continuous kneading device (1) includes a pair of kneading rotors (3), being capable of increasing mesh between the kneading rotors (3) while suppressing a kneading load applied to the kneading rotors (3). The continuous kneading device (1) includes a barrel (2) and a pair of kneading rotors (3) housed in the barrel (2) and rotating in mesh in directions different from each other. Each kneading rotor (3) includes a plurality of kneading flights (11, 15) for kneading a material supplied into the barrel (2). The kneading flights (11, 15) and respective portions of the barrel (2) housing the kneading flights (11, 15) respectively configure a plurality of kneading sections aligned axially of the kneading rotors (3). The material is fed axially from the upstream kneading section to the downstream kneading section to be sequentially kneaded. The kneading flight (15) constituting the downstream kneading section has a rotational outer diameter (D2) larger than a rotational outer diameter (D1) of the kneading flight (11) constituting the upstream kneading section.

    摘要： 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.
