摘要:
Respective outer peripheral surfaces (33, 35) of opening-side end portions (30, 31) of a front cover (12) and a pump shell (7), which have been shaped by pressing, are formed by slimming such that the outside diameters of the slimmed outer peripheral surfaces are equal to each other. With the opening-side end portions abutting against each other, a high-energy beam such as a laser beam (R) is radiated toward the abutment surfaces (30, 31) from the radially outer side to weld the abutment surfaces to each other. Consequently, it is possible to perform welding accurately through easy processing in order to easily manufacture a fluid coupling with high precision that facilitates post-processing.

A blade structure of a torque converter, having a plurality of blades, is produced according to processes. The processes has (a) stamping a plane plate into a first shape, the first shape has (i) the plurality of circumferentially arranged blades, (ii) ring-shaped first connecting portions, each of which integrally couples the adjacent blades together at an outer circumference side of the blade structure, and (iii) ring-shaped second connecting portions, each of which integrally couples the adjacent blades together at an inner circumference side of the blade structure, (b) curving a surface of the stamped blade, (c) inclining the blade at a predetermined angle with respect to the first and second connecting portions while inclining the first and second connecting portions, and (d) adjusting a distance between the adjacent blades and shrinking the first shape in a radial direction by the inclination of the first and second connecting portions.

An outboard engine system includes a casing (1) and an engine (E) mounted in an upper part of the casing. The casing also contains a torque converter (T), and vertically arranged output shaft (20) connected to a crankshaft (17) through the torque converter. In the torque converter, a turbine runner (26) is arranged above a pump impeller (25) and connected to the output shaft, and a transmission cover (29) is connected to an outer periphery of the pump impeller so as to cover an upper surface of the turbine runner. A drive plate (31) is secured an its central portion to a lower end of the crankshaft by a first bolt (32 1 ), and an outer peripheral portion of the drive plate is secured to the transmission cover by a second bolt (32 2 ). The torque converter is suspended from the crankshaft via the drive plate. Thus, it is possible to provide an outboard engine system which enables support of a torque converter without using any bearing exclusively for supporting the overall weight of the torque converter, thereby reducing the cost.
摘要:
Among first and second stators (40, 41) of a torque converter supported on a fixed part by a one-way clutch corresponding to the stators, the number of second stator blades (46) of the second stator (41) on the downstream side in the direction of flow of oil is larger than the number of first blades (42) of the first stator (40) on the upstream side, and the maximum value t2 for blade thickness of the second stator blade (46) is smaller than the minimum value t1 for blade thickness of the first stator blade (42). Therefore, it is possible to ensure that there is a sufficient gap (²) between a trailing edge (42b) of the first stator blade (42) and a leading edge (46a) of the second stator blade (46), thus preventing the flow of oil from being stopped by the gap (²), and it is possible to align effectively the flow of oil by means of the second stator blades (46), which are larger in number, thereby achieving a balance between improvement of the torque ratio and improvement of the capacity coefficient of the torque converter.
