摘要： A balanced speed reducer of a dual-sun gear variable-line-speed planetary row includes a dual-sun gear variable-line-speed planetary row, an input end, an output end, a locking end, and auxiliary devices such as bearings. The dual-sun gear planetary row includes a left sun gear, a right sun gear, and a planet carrier. A left planetary gear and a right planetary gear that are connected on each planetary gear shaft have the same rotation speed. The left planetary gear meshes with the left sun gear, and the right planetary gear meshes with the right sun gear. The number of gear sets is not less than two. A teeth number combination and a number of gear sets are set according to a range specifying parameter and following a principle of matching the teeth number combination with the number of gear sets.

摘要： A linear actuator is disclosed having a housing and a plurality of components arranged in the housing. The actuator may include at least one conducting component, a group of mechanical, non-conducting components including components of a spindle mechanism, and at least one bearing arrangement designed to support components of the spindle mechanism in the housing. The at least one conducting component may be separated from the group of mechanical, non-conducting components by at least one seal in such a way that two mutually separate spaces sealed off from one another are formed within the housing.

摘要： A gear transmission mechanism includes a second gear, a first gear forming tooth portions at an outer circumference of a sector-like gear body for meshing with the second gear, and a rotation restricting mechanism for setting a rotation limit of the first gear. The rotation restricting mechanism includes an abutment portion provided in the first gear and a stopper provided in the housing. At least one of an abutment face in which the abutment portion comes into abutment against the stopper and a stopper face in which the stopper comes into abutment against the abutment face includes an inclination portion for creating a component force from rotational force of the sector gear at the time of mutual abutment.

摘要： A ball screw device is provided, including a retainer that can properly retain balls. The difference between a diameter being the pitch circle diameter of the ball screw device and the outside diameter of the rack shaft is set to be equal to or larger than the difference between the bore diameter of a ball screw nut and the diameter. The thickness center diameter of the retainer is set to be smaller than the diameter. Even when the inclination angle is reduced, the clearance between the inclined surfaces of each retainer groove on the radial inside can be easily set to be smaller than the diameter of the balls because the bore diameter of the retainer is set to be smaller. Thus, even when the inclination angle of the inclined surfaces is set to be smaller, the balls can be properly retained.

摘要： To improve workability and sealing performance of a coolant when a plurality of nuts in a ball screw are brought into contact with one another, the plurality of nuts being coupled to one another, assembled to one threaded shaft and cooled by flowing the coolant through through-holes formed in the plurality of nuts in axial directions of the plurality of nuts. The ball screw includes counterbores of the through-holes formed on opposing end faces of both of adjoining nuts, and a ring-shaped sealing member inserted thereto. The counterbores are formed such that a depth of one counterbore is larger than a length of the sealing member, and the a depth of the other counterbore is smaller than the length of the sealing member, and such that circumferential positions of the counterbores of the adjoining nuts face each other when a desired preload is exerted.
