Effect of the Application of Carbon Tetrachloride Lubricant to a Cutting Operation by Abass Ali saleh

“… In this research CCl4 as a lubricant is used for machining copper specimens. It was noticed that CCl4 has many effective effects at low machining speed, as well the effect at highspeed cutting vanished which is coincided with the results obtained by the researchers workedin this field and giving the cause of their results either for lubricant penetration loss at theinterface between the chip 0.005 m/sec, the cutting ratio (r) increases by more than 23% anddecreases to 7% at a cutting speed of 0.08 m/sec, on other hand the friction angle decreasesfrom about 37% to 11% as the cutting speed increases from 0.005 m/sec to 0.08 m/sec. …”

حساب الضّياعــات الميكانيكيّــة في آلية نقل الحركة لعنفة ريحية وتأثيرها على المردود by انديرا سليمان

“…Our research includes the transmission mechanism of the wind turbine and the calculation of losses, such as loss of mechanical ventilation and friction loss and the loss of lubrication between the gear teeth design.  Aims and access to high reliability work and thus obtain high efficiency and taking advantage of electronic programs, We observed that each type of previous losses have an impact on the overall loss of Gearbox, Depending on the working conditions, For example, at low speeds, loss of friction between the teeth is a great percentage of the total loss, And thus controls the overall efficiency of the transport system, while at high speeds noticed this low percentage of loss, while the loss of lubrication and ventilation rate rose. …”
