    摘要: A variable displacement hydraulic motor having a swash plate angle adjusting structure. This hydraulic motor has a main case, a rotary shaft rotatably supported in the main case, a plurality of cylinder blocks rotatable with the rotary shaft and including axial plungers, a swash plate member for contacting distal ends of the plungers, pivot shafts for pivotally connecting the swash plate member to the main case such that the swash plate member has a pivoting angle adjustable relative to the main case, and a first and a second hydraulic cylinders arranged at opposite sides of the pivot shafts as seen in a direction parallel to the rotary shaft. The first and second hydraulic cylinders are secured in a region of the main case opposed to the cylinder blocks across the swash plate member. The hydraulic cylinders are operable to contact the swash plate member to adjust the pivoting angle thereof.

    摘要: An apparatus for winding a web material such as paper or plastic film about a hollow core. The core is disposed between a pair of shafts spaced from and axially opposed and aligned with each other. The core is fixed at opposite ends to the shafts respectively. At least one of the shafts is connected to and rotated by a motor. Each of the shafts is comprised of an annular slide disposed around and coaxially to the shaft for axial movement relative to the shaft, and tapered surfaces formed on the circumferential outer surface of the slide. A plurality of tins are angularly spaced from each other along the circumference of the slide and engaged with the tapered surfaces. The tips are radially movable relative to the shaft. Each of the shafts includes a piston inserted into a bore in a cylinder, the piston being opposed to and engaged with the slide axially of the shaft, whereby the tips can be pressed against the inner surface of the core by the fluid pressure in the cylinder and under the effect of the tapered surfaces, to thereby fix the core to the shaft. Furthermore, at least one of the shafts is restrained from movement relative to the shaft in the rotational direction of the shaft to transmit a torque to the slide from the shaft, the tips on that slide also being restrained from movement relative to the slide in the rotational direction of the shaft to transmit torque to the tips from the slide.
