Multiple V-Belt Drives are used for transmitting from fractional to 6000 horsepower constant speed, and to 300 horsepower adjustable speed. The V-belt design utilizes angled sides to transmit power through a V-grooved pulley by wedge contact between the angled sides of the belt and the angled sides of the groove. The multiple V-belt drive has supplanted the flat belt drive … Read more
Rotary Blower for pressure and vacuum service is universally used with gas or oil burners, furnaces forges, ovens, etc. Two inter-engaging impellers, rotating in opposite directions draw air into the pockets between the impellers and the case, and force this air into the discharge pipe. The amount of air displaced by these impellers at each revolution … Read more
BEARINGS, Ball and Roller Chief advantage of the ball bearing is its low coefficient of friction which does not increase at the instant of starting in motion. Other advantages are: economy of space; simplicity of lubrication; practical elimination of wear due to the rolling point contact and the extreme hardness of contact surfaces obviating the … Read more
