Abstract: A speed reduction mechanism with radial output is disclosed. The roller reduction mechanism includes a speed reducer and an output shaft structure. The speed reducer has an input side and an output side. The output shaft structure is fastened at the output side of the speed reducer and is driven by the speed reducer to rotate. The output shaft structure is combined with the speed reducer and a first bearing and a second bearing with tapered shapes respectively is sleeved at a pivot shaft of the output shaft structure, so that the speed reducer may bear a larger axial force and the first and second bearings with tapered shapes respectively may increase a lateral force of the output shaft structure.

Abstract: “An actuating device comprises a speed reducer, a fixing member, and a driven member. The speed reducer has an input side, a rotation portion, and an output side. The input side and the output side are respectively arranged at two sides of the rotation portion in an axial direction thereof. The input side or the output side of the speed reducer is fixed at the fixing member. The driven member may be a tire and covered an outer peripheral of the rotation portion. The width of the actuating device becomes thinner and the volume of the actuating device becomes small to make it install to a targeting object (automatic guided vehicle) much easier.

Abstract: A speed reducer comprises a sleeve-shaped rotation member, a rear carrier, a front carrier, three driving assemblies, a third bearing set, a fourth bearing set, and three wheels. When a shaft of a motor inserts into the front central through hole, each axial hole of each wheel, and the rear central through hole and then drives each driving assembly to rotate, the first bearing set and the second bearing set both operate to an inner peripheral of each corresponding through hole of each wheel and the outer rollers of each wheel drive the inner rollers of the sleeve-shaped rotation member due to the eccentric arrangement of the first rod section and the second rod section of the eccentric rod so as to drive the sleeve-shaped rotation member to rotate and then achieve the effect of reducing speed.

Abstract: A speed reducer includes a rotation member including internal main rollers; a rear carrier including a central through hole and eccentric stepped-diameter holes; a front carrier including a central through hole and recesses; a front wheel including a first through hole, second through holes, and front rollers on an edge to be in contact with the main rollers; a rear wheel including a third through hole, fourth through holes, and rear rollers on an edge to be in contact with the main rollers; coupling members for holding the front carrier, the front wheel, the rear wheel, and the rear carrier together; outer gear assemblies each rotatably disposed in the eccentric stepped-diameter hole, the fourth through hole, the second through hole, and the recess; and a central gear unit being in gear mesh with the outer gear assemblies.

Abstract: A full-roller transmission structure comprises a housing, a first disk, a second disk, a rear disk, a front disk, and an input shaft. The housing includes a rear cover, an annular shell, and a front ring, which are detachably coupled together. Multiple inner rollers are disposed on an inner surface of the annular shell. The first and second disks are mounted in the annular shell and respectively provided with a plurality of first and second outer rollers capable of acting on the inner rollers. The rear disk is mounted between the first disk and the rear cover. Joining bolts and joining pins are employed to join the above disks. The input shaft includes a first eccentric journal for the first disk and a second eccentric journal for the second disk, the first eccentric journal being offset from the second eccentric journal at an angle of about 180 degrees.
