A rotary moto actuator with a base, a table, a statorand a rotorof a rotary motorand a first memberand a second memberof a guide mechanismthat have a plurality of base segments, a plurality of table segments, a plurality of stator segments, a plurality of rotor segments, a plurality of first member segmentsand a plurality of second member segments, respectively, which all arranged circumferentially around a center line C. The stator segmentsare connected to the base segments, to which the first member segmentsare connected. The rotor segmentsare connected to the table segments, to which the second member segmentsare connected.

Rotary motor actuator and horizontal axis wind turbine

A rolling-element screw device includes: a large number of rolling elements; a screw shaft having an outer periphery on which a rolling groove for the large number of rolling elements is helically formed; a nut member which has a through-hole through which the screw shaft is passed and which is threadedly engaged with the screw shaft through intermediation of the large number of rolling elements; a lubricant supply hole formed through the nut member from an outer peripheral surface of the nut member to an inner peripheral surface of the nut member; a lubricant tank mounted to the outer peripheral surface of the nut member and comprising an accommodating chamber for lubricant; and a lubricant applying body standing from the lubricant tank, and inserted into the lubricant supply hole along with amounting operation of the lubricant tank with respect to the nut member.

Rolling element screw device

There is provided a new rolling body screw device manufactured with cheap cost without degrading quality in comparison with a conventional device even for a device having any large dimension in an end-cap type rolling body screw device. The rolling body screw device includes the direction changing passageseach including: a scoop-up portionscooping a ball rolling in a loaded rolling body passage as a loaded area of the endless track so as to hand over the balls to the direction changing passageas a non-loaded area of the endless track; and a route pathforming a circulation path of the ball scooped by the scoop-up portion. Each of the return pieces is composed, in combination, of a metal partformed of a metal material including the scoop-up portion, and non-metal partsformed of a non-metal material including the route path
