摘要： PROBLEM TO BE SOLVED: To provide a novel blend round in which a cost and performance can be compatible with each other by setting specific dimensionless values R/O of a curvature radius R of the blend round with respect to a blade throat width O in sections between a rear edge of a blade and a throat, the throat and a branch point, and the branch point and a front edge of the blade. SOLUTION: A first section A from a rear edge 1a of a blade profile to a throat 4 is formed such that a dimensionless value R/O of a curvature radius R of a blend round with respect to a throat width O is maintained at about 0.4. A second section B from the throat 4 upstream to a branch point 7 at a distance substantially equal to a throat length is formed such that the value R/O is consecutively and linearly varied from about 0.4 to about 0.7. In a third section C from the branch point 7 to a front edge 3a of the blade profile, the entire blend round is formed such that the value R/O is maintained at about 0.7. Consequently, it is possible to enhance performance and enlarge the blend round so as to reduce a machining cost.

摘要： PROBLEM TO BE SOLVED: To reduce loss that turbine exhaust is produced and improve the performance of an exhaust chamber in an annular exhaust chamber arranged in an axial flow turbine outlet, by forming a fin extended from the peripheral side of an exhaust chamber inlet to the approximately center part of the exhaust chamber and a channel smoothly curved between the fin and an exhaust chamber inner wall. SOLUTION: In this exhaust chamber arranged in the outlet part of an axial flow turbine, a fin 4a extended from the peripheral side of an exhaust chamber inlet 1 is formed into a shape which is smoothly curved having an interval approximately in parallel with an exhaust chamber inner wall 3, and also an exhaust channel 7 formed by the fin 4a and the exhaust chamber inner wall 3 is formed as a smooth enlarged passage. This fin 4a is folded back according as it is directed to a downstream side and has a part in parallel with a turbine rotary shaft 5, and the end of the fin 4a is positioned in the approximately center of the inner cross section of the meridian plane of the exhaust chamber. Hereby, loss in an exhaust chamber inflow part can be suppressed to the minimum extent, and the end part of the fin 4a is positioned in the approximately center of the cross section of the meridian plane of the exhaust chamber, therefore a large scale slewing flow can be suppressed and the loss can be reduced.

摘要： PROBLEM TO BE SOLVED: To sufficiently lubricate the whole surface of a tooth meshing part. SOLUTION: An oil supply passage 13 is formed on an external gear 4, which is opened to a tooth bottom 14 meshed with an internal gear 2 and extended on a longitudinal direction of the tooth for supplying oil by centrifugal force due to rotation. Oil is directly injected to the meshing parts between the internal gear 2 and the external gear 4. It is thus possible to directly supply cold oil to maximum temperature parts whose surfaces are easily damaged, sufficiently lubricate surfaces of teeth of the meshing parts, and effectively prevent occurrence of damage of the tooth surfaces with a small amount of oil.

摘要： PROBLEM TO BE SOLVED: To properly cope with center deviation of an angle of a rotary shaft, that is, vertical dislocation of an axis from a horizontal surface with a facilitated and simplified structure. SOLUTION: Journal bearing shells 2 each having a spherically projected outer peripheral surface are supported by bearing housings 3a, 3b having spherically recessed surfaces in sliding contact therewith. Thrust bearings 4 are combined with the side surfaces of the journal bearing shells 2. In such a sliding bearing, the bearing housings 3a, 3b are connected with journal bearing shells 2 by means of a pair of bilaterally aligning pins arranged on a plane including a center point of the spherically projected surfaces on the outer peripheries of the journal bearing shells 2. With such a setup, it is thus possible to allow an axis of a rotary shaft to be dislocated vertically from a horizontal surface and inclined.
