A conventional movable blade water turbine runner is shown in Fig. 1. That is, a reciprocating hydraulic servo motor cylinder 6 is installed in the runner boss 2 and serves as a driving source for operating the runner vane, and together with a fixed piston 7 and the like constitutes a hydraulic servo motor.

部の詳細を第２図に示す。 This lubricating oil 28 is installed above the generator through the inner hole of the oil communication pipe 11, and an overflow pipe is provided so as to maintain a constant oil level at all times.
Its upper part opens into an oil tank chamber (not shown) designed to maintain atmospheric pressure. Therefore, even if servo motor pressure oil leaks from the part shown in FIG. The oil is stored in a leakage storage tank (none of which is shown) through an oil tank chamber overflow pipe installed above the generator, and is arranged so that it is returned to the servo motor pressure oil system. The details of the portion shown in FIG. 1 are shown in FIG. 2.

6. When using oil-free bearings for the runner vane inner bearing 17, link pin bearing 15, servo motor lower guide bearing 32, etc., fill the runner boss 2 with air (without using lubricating fluid) or fresh water. It is better to take advantage of the low friction lubrication effect. This filled water does not damage the lubricating film of the oil-free bearing as described below, has a good heat dissipation effect, and can form a water film on the sliding surface, which has the advantage of making the bearing low in friction.

ている。 On the other hand, if oil leaks from the sliding part oil sealing packing 29 of the hydraulic servo motor cylinder 6 built into the runner boss 2, it will enter the inner surface of these oil-free bearings and form firmly on the sliding surface. In order to cause damage to the stable solid lubricant film that has been applied to the This can lead to major damage such as jamming, overheating, seizure, and abnormal wear. Figure 6 shows a typical example of this. When lubricating oil is mixed in, the amount of bearing wear is greater than that under water lubrication, and furthermore, as the surface pressure increases, the amount of wear increases abnormally, a so-called boundary. This indicates that it is easy to fall into a lubrication state.
