摘要： A reduction gear device utilized in a joint portion of an industrial robot, durability of the reduction gear device being increased in the case where torque applied to the reduction gear device is high and the reduction gear device is utilized at a high operation rate.In a reduction gear device is provided with a first reduction mechanism and a second reduction mechanism, and the second reduction mechanism includes an external gear that revolves eccentrically, an internal gear that causes orbital revolution of the eccentric movement of the external gear, and an output shaft on either the external gear or the internal gear. In this reduction gear device, in the case where the relationship between an inner diameter D of the internal gear and torque T created by the output shaft fulfills a specific condition, when the reduction gear is operated, makes the density of iron powder adulterated within lubrication sealed within the reduction gear device to be equal to or less than 600 ppm after the pace of increase in density had stabilized. Further, in the case where the relationship between the inner diameter D of the internal gear and the torque T created by the output shaft fulfills the specific condition, the number of teeth of the internal gears is less than a predetermined number of times the difference in the number of teeth between the internal gear and the external gear.

摘要： A brake actuator for an electrical parking brake comprises an electric motor and a planetary gear set. The axes on which the planet wheels are carried on the planet carrier are joined substance-to-substance to the planet carrier, i.e. formed in one piece with it or for instance mounted on its surface by means of atomic or molecular forces. Recesses on the axes can receive a lubricant. Spacers between the planet carrier and planet wheels can reduce the contact surface in the axial direction.

摘要： An electric power steering apparatus is provided with a worm which is a driving gear interlocked with an electric motor for assisting steering, and a worm wheel which is a driven gear having an annular teeth body made of synthetic resin meshing with the worm and a metallic core body coupling the annular teeth body and is attached to the steering shaft. Protrusions are provided on a side surface of the annular teeth body in a face width direction at a plurality of circumferential positions from which a distance to a center of rotation is different from each other, and stirred lubricating fats and oils applied around the worm wheel. As a result, the lubricating fats and oils can be moved to between tooth surfaces of a meshing portion between the worm and worm wheel.

摘要： Disclosed herein is a new improved large planetary gear system used on the input stage of wind turbine power generators. This improved planetary gear system reduces or eliminates lubricant debris traditionally generated from the gear teeth, thereby eliminating an initiating source for bearing failure. To achieve these results, some and preferably all of the gear teeth within the planetary gear system are superfinished using chemically accelerated vibratory finishing to a surface roughness of approximately 0.25 micron or less. Several objects and advantages of the invention are to provide a gearbox with reduced metal debris, improved bearing life, reduced wear, reduced vibro-frictional noise, improved contact fatigue, improved fretting resistance, improved lubrication, to simplify the run-in process, and to enhance the durability and efficiency of the gearbox.
