摘要： A transmission mechanism includes a housing, a first rotating member accommodated in the housing and rotatable about a first rotating member axis, and a lubricating member accommodated in the housing and containing a lubricant. While the first rotating member rotates about the lubricating member, the lubricating member applies a preload to and comes into contact with a part of the first rotating member on the basis of an elastic force, so that the part of the first rotating member is lubricated with the lubricant.

摘要： An actuator includes a motor including a first rotor rotatable in a circumferential direction, and a stator to drive the first rotor; a second rotor rotatable in the circumferential direction; and a speed reducer that reduces rotation of the first rotor and transmits a torque to the second rotor via a bearing. The first and second rotors include first and second tube portions extending in an axial direction, respectively. The second tube portion is radially outward of the first tube portion. A lubricant is filled in a filling space including at least a portion of a space between an outer surface of the first tube portion and an inner surface of the second tube portion. The actuator includes a width reducing portion that reduces a width of the filling space in a radial direction in at least a portion of the filling space in the axial direction.

摘要： A spur gear transmission has at least two toothed spur gears, the toothings of which are in meshing engagement with one another and which are each rotatable about an axis of rotation. An enveloping wall encloses the two spur gears in a circumferential direction and in the direction of the axes of rotation. The enveloping wall has an inner contour which is adapted to the outer diameters of the spur gears such that ring-shaped gaps that merge into one another are formed between the enveloping wall and the spur gears. Each ring-shaped gap is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a multi-part housing which is closed along a parting joint. The parting joint extends partially or entirely substantially within a plane in which one of the two axes of rotation or both axes of rotation run.
