The Dana/Spicer Model 44 is an automotive axle manufactured by Dana ... Gear ratios range from 2.72:1 to 5.89:1 ... On some differentials only the high speed 2.72–3 ...
The tip-speed ratio, λ, or TSR for wind turbines is the ratio between the tangential speed of the tip of a blade and the actual speed of the wind, v. The tip-speed ratio is related to efficiency, with the optimum varying with blade design. [1] Higher tip speeds result in higher noise levels and require stronger blades due to larger centrifugal ...
The Dana/Spicer Model 80 is an automotive axle manufactured by Dana Holding Corporation and has ... Ring gear measures 11.25 inches (286 mm). ... Gear ratios: 3.23, 3 ...
A variation of the Dana 60 known as a Dana 61 was made to accommodate gear ratios that allowed for better fuel mileage. This was done as a direct result of the 1973 oil crisis. A 3.07:1 gear ratio was common for these axles and unachievable in a regular Dana 60. To allow for the different gearing, the Dana 61 had a greater pinion offset.
Crawl ratio is a term used in the automotive world to describe the highest gear ratio that a vehicle is capable of. Note that gear ratio, also known as speed ratio, of a gear train is defined as the ratio of the angular velocity of the input gear to the angular velocity of the output gear, and thus a higher gear ratio implies a larger speed reduction, i.e. the input speed is reduced more at ...
The "Spicer Electrified eS9000r e-Axle" is a hybrid, electrified version of the Dana 110/Dana 111/Dana 135 axles. It will not see action in trucks, making this a hybrid axle for medium-duty trucks only. Since the hybrid axle is based on axles that have been used in many trucks, for many years, it is also referred to as a drop-in axle.
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
The Dana/Spicer model 53 is an automotive rear axle produced by Dana-Spicer used in medium to heavy duty truck applications. The Dana/Spicer model 53 (Dana 53) is a semi-float axle that was produced from 1947–1965, [1] both with a 53 differential and wheel ends, and with a Dana 44 differential and Dana 53 wheel ends.
