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.

Speed reducer capable of changing speed

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.

Speed-switchable reduction gear

In a resin granulating apparatus of the present invention, a bracket extending in the outward radial direction over an outer peripheral surface of a sleeve is provided for the sleeve for rotatably supporting a cutter shaft of a cutter for shearing a material extruded from a die. Stopper means cooperating with the bracket to regulate movement of the sleeve toward the die and moving a regulation position in the axial direction is provided on the radially outer side over an outer diameter of the sleeve. With such a configuration, installation space is compactified so as to additionally provide the stopper means in the existing facilities, and a position of the cutter relative to a die surface is precisely adjusted so as to stably produce a pellet of a best shape.

Resin granulating apparatus

A cutter machine has a knife holdermounted onto a cutter shaftat the center portion, wherein a material to be cut is cut with knivesmounted onto the outer circumference of the knife holderby rotating the knife holderaround the cutter shaft. The knife holderis separated into a fixing membermounted onto the cutter shaftand a mounting memberonto which the knivesare mounted. The mounting memberis pivotally supported around two axes with respect to the fixing member. In the cutter machine, the knives and a die plate come into contact with each other by a small press force of the knives, thereby enabling a satisfactory cutting to be obtained.

Cutter machine

A die for manufacturing resin pellets capable of processing a die plate easily, and achieving simplification of a construction of heat channels and enhancement of heating efficiency. A die for manufacturing resin pellets provided with a number of nozzle orifices in the outer surface of the die, there are provided a plurality of rows of heat channels which extend in a direction crossing the resin channels in the vicinity of the outer surface of the die and are arranged along the resin channels . At least one of an introducing course and a discharging course for a heat medium in the plurality of heat channels
