Abstract

PURPOSE:To reduce bending moment acting on a guide piston and improve the durability of the swash plate mechanism by arranging the center of a floating plate eccentrically with respect to the rotating center of the swash plate. CONSTITUTION:A sliding contact groove 10 on the upper surface of the swash plate 3 is arranged eccentrically by the amount of (a) with respect to the axial center X of a rotary shaft 7 or the rotating center of the swash plate 3 while the annular floating plate 4 is arranged in the eccentric sliding contact groove 10. The sliding contact groove 11 of the lower surface of the swash plate 3 is arranged eccentrically into the opposite direction of the same groove 10 on the upper surface of the swash plate 3 by the amount of (a'). A contacting surface between a shoe 6 and the floating plate 4 is secured sufficiently at a part whereat a force acts on the shoe 6. According to this method, the thickness of a part of the swash plate 3 in the direction of the main shaft is made thick by an amount corresponding to the eccentricity between the sliding contact grooves 10, 11 of the upper and lower surfaces of the swash plate, therefore, the bending moment, acting on the guide piston, may be reduced.

It has a shoe 6 interposed between the piston 5 and the floating plate 4. The rotation of the swash plate 3 by the rotating shaft 7 causes the actuating piston 2 to reciprocate via the guide piston 5. Conversely, the reciprocating movement of the actuating piston 2 rotates the swash plate 3 and the rotating shaft 7 via the guide piston 5.

肉部分が破損することになる。The floating plate 4 has a ring shape and is placed in annular sliding grooves on the upper and lower outer peripheries of the swash plate 3. As shown in FIG. Since the outer peripheral edge of the floating plate 4 and the outer peripheral surface of the swash plate 3 are aligned with each other in the direction shown in FIG. 1, the cross section perpendicular to that shown in FIG. ), the outer peripheral edge of the floating plate 4 extends outward from the outer peripheral surface of the swash plate 3. For this purpose, the receiving groove 8 of the swash plate 3 of the guide piston 5 is cut deeply to prevent the outer peripheral edge of the floating plate 4 from coming into contact with the groove wall surface 9. However, such machining of the receiving groove 8 does not reduce the wall thickness of the groove wall surface 9, and may cause distortion between the actuating piston 2 and the guide piston 5. The bending moment acting on the groove wall surface 9 causes damage to the thin wall portion.

厚にさせることができる。As is known, the shoe portion of the swash plate moves in a sine curve, with its top receiving a force from above and its bottom receiving a force from below. Since the floating plate is eccentric to the swash plate in the direction of the part that receives this force,
A sufficient contact surface between the floating plate and the shoe is always ensured. Furthermore, since such eccentricity eliminates the extension of the outer peripheral edge of the floating plate from the outer peripheral surface of the swash plate as shown in FIG. Parts can be made thicker.

本発明では、斜板に対し浮動板を偏心させて配するのみ
であるから、その加工、組付けはきわめて容易である。In the present invention, since the floating plate is simply arranged eccentrically with respect to the swash plate, its processing and assembly are extremely easy.

A ring-shaped floating plate 4 is arranged. Further, the sliding groove 11 on the lower surface of the swash plate 3 is eccentrically moved to the left by an amount a' as viewed in FIG. 3, and the ring-shaped floating plate 4 is disposed in the eccentric sliding groove 11.

確保される。The sliding grooves 10 and 11 are installed so that the outer peripheral edge of the floating plate 4 and the outer peripheral surface of the swash plate 3 are aligned at the portions 12 and 13, as shown in FIGS. 3 and 4. Furthermore, the outer circumferential edge of the floating plate 4 is located inward from the outer circumferential surface of the swash plate 3 at the 140 portion. However, since the direction of the force acting on the shoe 6 is the direction of the arrow in FIG. 3, a sufficient contact surface between the shoe 6 and the floating plate 4 is ensured at the portion where the force acts on the shoe 6.
