Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To reduce a manufacturing cost and a maintenance cost by providing a winding transission train having a winding intermediary node for transmitting rotation of a driving rotary body to a driven rotary body by being wound round the driving rotary body and the driven rotary body. SOLUTION: In a multistage pump device, a plastic-driving wheel 21, a driven wheel 22 and a rubber timing belt 24 are adopted to transmit rotation of the driving wheel 21 to the driven wheel 22 by the timing belt 24 to thus transmit rotation of a driving shaft of a motor M to first/second shafts 7, 8 of a multistage Roots pump P to thereby obviate maintenance such as addition and the replacement of lubricating oil. Since the rotation is transmitted via the timing belt 24, a relatively thin object can be adopted as the driving wheel 21 and the driven wheel 22. Thus, this multistage pump device can reduce a manufacturing cost and a maintenance cost.

Title: Integral shrouded blade
Inventor: OKADA YUKIMASA
IPC: F01D5/22
Filed: 1993-12-09
Abstract: PURPOSE:To improve the centrifugal strength of an integral shrouded blade by a large margin and improve aerodynamic performance by forming a shroud, formed at the tip of the blade, into such cross-sectional shape that lift acts downward. CONSTITUTION:An integral shrouded blade 1 is formed of a profile part 2, a blade root part 3 and a shroud 4 integrally formed at the tip of the profile part 2. The shroud 4 is formed into the inverted cross-sectional shape of the blade profile. Downward force thereby works on the shroud 4 by the vertical relative flow during the rotation of the integral shrouded blade 1. This force is proportional to the length of the shroud 4 and also to the square of the relative inflow speed so as to become larger as the blade is longer and the rotating speed is higher. This force can cancel the centrifugal force of the shroud 4 satisfactorily. The centrifugal strength of the integral shrouded blade can be thus improved by a large margin, and aerodynamic performance can be also improved.
