This paper describes the experimental study of the shaft oil feed mechanism of a rotary compressor. The oil contained in the shaft in which an oil pump is inserted is fed to the respective sliding surfaces of the subbearing section, eccentric section and main bearing section of the shaft by centrifugal force of shaft rotation. The oil feed pressure of shaft rotation is approximately 0.1 kg/cm2 ...

Due to their high strength and favourable mechanical behaviour, metals are used in a variety of applications within the automotive industry, including drive shafts. However, use metallic shafts sector presents some disadvantages such as inertial masses. This work investigates benefits using Carbon Fibre Reinforced Polymers (CFRP) for manufacturing A Formula Student car was model present design ...

PURPOSE To evaluate clinical and radiographic outcomes in patients treated with limited-open retrograde intramedullary headless compression screw (IMHS) fixation for metacarpal neck and shaft fractures. METHODS Retrospective review of prospectively collected data on a consecutive series of 39 patients (34 men; 5 women), mean age 28 years (range, 16-66 y) treated with IMHS fixation for acute d...

This paper set out to establish the dynamics model of shaft torsional vibration for direct-drive wind turbine with phenomenon unstable system vibration. The stability equilibrium point dynamical is investigated, and Routh–Hurwitz criterion used obtain a range values bifurcation control parameters. For stable point, domain calculated by constructing Lyapunov function. sensitivity analysis parame...
