Title:
METHOD FOR MANUFACTURING FLUID POWER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2013/172158
Kind Code:
A1
Abstract:
The method for manufacturing fluid power transmissions sequentially performs: a first process of assembling a provisional blade-core assembly (38) obtained from connecting multiple blades (2b) to a core (2c) so as to move freely by lining up the multiple blades (2b) on a blade alignment jig (J1) and superposing the core (2c) above the group of blades (2b) while loosely inserting protruding pieces (30) provided on each blade (2b) in engaging holes (31) provided on the core (2c) and then bending the tips of the protruding pieces (30) so as to keep the protruding pieces (30) from slipping out of the engaging holes (31); a second process of setting the provisional blade-core assembly (38) at a prescribed position on the inner surface of a shell (2s); and a third process of soldering the protruding pieces (30) to the engaging holes (31) and the blades (2b) to the shell (2S), respectively. As a result, ease of assembly is favorable and it is possible to bond the three parts, the shell, the blades and the core, without strain and obtain a high quality impeller for a fluid power transmission.
