There is one in which the swash plate is supported movably in the circumferential direction of a semi-cylindrical shape by interposing a roller bearing. In this case, it is necessary to properly hold the roller bearing between the swash plate and the support member so that it does not shift or fall off due to vibration or impact. A holding rod 15 and a supporting frame 6 are used (Japanese Patent Publication No. 45313/1986).

保持する。 When the swash plate 1 is rotated via the lever 9, the swash plate 1
is displaced while rolling the roller bearing 3 along the concave surface portion 2A of the support member 2. Further, the holding rod 15 rotates around the node 19 with the support member 2, and slides inside the pins 17 and 18 in the axial direction, rotationally displacing the pins 17 and 18, and relatively displacing the support frame 6. It is held at an intermediate position between the support member 2 and the swash plate 1.

The cylinder 20 is formed in a cylinder block 23 parallel to a rotating shaft 24, and the rotating shaft 24 is connected to the swash plate 1.
It penetrates the roller bearing 3 and freely rotates and protrudes to the opposite side via the bearing 25 provided on the support member 2.

These parts are preassembled on the outside and fixed inside the casing. However, since the assembly order is limited in this way, there is a problem in that it becomes difficult to assemble other members.

了する。(Function) Since the support frame of the roller bearing, the support member and the holding rod are connected without using a connecting member,
The number of required parts is small, and the device can be assembled by engaging the middle part of the holding rod pin-coupled to the swash plate with the notch in the support frame, and inserting the end of the holding rod into the guide hole of the support member in the direction of the rotation axis. Just insert it from there.

する支持枠６の内側に回転自由に支持される。 Reference numeral 1 denotes a swash plate having a semi-cylindrical back surface 1A, which is supported via a plurality of roller bearings 3 by a support member 2 which has a concave surface 2A of the same shape opposite to the back surface 1A, and is used to drive a lever 9. It rotates in the vertical direction in the figure. The roller bearing 3 is rotatably supported inside a support frame 6 curved in an arc shape.

欠７の内側に緩く係合する。 To hold the support frame 6 in the proper position between the swash plate 1 and the support member 2, retaining rods 5 are provided on the sides of the swash plate 1.
The proximal end of is rotatably attached via pin 4. Further, a notch 7 that opens laterally is formed in the support frame 6, and the intermediate portion of the holding rod 5 is loosely engaged inside this notch 7.

例と同様である。 The tip 5A of the holding rod 5 is formed into a spherical shape or a horizontal cylindrical shape perpendicular to the axis of the holding rod 5, and this tip 5A fits into a guide hole 8 formed in the support member 2. This guide hole 8 is formed substantially parallel to the rotation axis of a piston (not shown) that passes through the swash plate 1 . Further, the opening portion of the guide hole 8 is formed wide in the direction of displacement of the swash plate 1 so as not to hinder the rotation of the rod 5. Note that the other configurations are the same as those of the conventional example.
次に作用を説明する。 Next, the effect will be explained.

れらの間から脱落したすることはない。 At the position shown by the solid line in FIG. 1, the swash plate 1 is substantially perpendicular to the rotating shaft (not shown), and the tip 5A of the rod 5 has entered the guide hole 8 most deeply. When the swash plate 1 is rotated from this position in the direction shown by the chain line in the figure by driving the lever 9, the holding rod 5 is moved toward the lower left in the figure, and the holding rod 5 has a spherical or cylindrical tip. At the same time, the distal end portion 5A is displaced toward the opening of the guide hole 8 while being rotated downward about the fulcrum 5A. Further, the intermediate portion of the holding rod 5 is slightly displaced in the axial direction with respect to the notch 7, and the swash plate 1
This guides the displacement of the support frame 6 which is displaced in the same direction.
In this way, the support frame 6 is held at an intermediate position between the swash plate 1 and the support member 2, which are relatively displaced. Therefore, the support frame 6 supporting the roller bearing 3 will not change its position relative to the swash plate 1 or the support member 2 due to vibration or the like, nor will it fall out from between them.

きる。 In addition, to assemble the bearing regulating device including the support frame 6 and the support member 2, the intermediate part of the holding rod 5 whose base end is connected to the swash plate 1 is engaged with the notch 7 from the side of the support frame 6. It is sufficient to simply insert the cylindrical tip portion 5A into the guide hole 8 of the support member 2, and there is no need to use a connecting part. For this reason, it is not necessarily necessary to fix it to the casing in the assembled state.
For example, it is also possible to assemble the support member 2 by first fixing it to the casing, and then inserting the support frame 6 and the swash plate 1 together with the holding rods 5 into the inside of the casing.

Since the holding rod is loosely engaged with the notch and the spherical or cylindrical tip of the holding rod is inserted into a guide hole formed in the support member approximately parallel to the piston rotation axis, the holding rod has fewer components. The assembly of the bearing restraint device including the retaining rod is extremely simple. This also facilitates the assembly of rotary piston pumps and motors using this type of device.
