Worm Gears Explained - Machinery Lubrication
The first one is the high reduction ratio. A worm gear can have a massive reduction ratio with little effort - all one must do is add circumference to the wheel. Thus you can use it to either greatly increase torque or greatly reduce speed. It will typically take multiple reductions of a conventional gearset to achieve the same reduction level,Dissimilatory nitrate reduction to ammonium - Wikipedia,High electron donor (organic carbon) to acceptor (nitrate) ratio; High summer temperatures and low NO 3 − concentrations; High sulfide concentration can inhibit the processes of nitrification and denitrification. Meanwhile, it can also enhance dissimilatory nitrate reduction to ammonium since high sulfide concentration provides more electron,Gear train - Wikipedia,The ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set.

It is possible to design gear teeth for gears thatBUN creatinine ratio normal range | High, Low BUN,,Apr 24, 2018· BUN Creatinine Ratio Low Levels. A low BUN to creation level is below 10:1.The ratio may decrease as a result of decreased urea formation and malnutrition. Renal damage also causes a reduction in reabsorption of BUN thereby reducing the ratio of BUN: Cr.Effect of roll speed ratio on the texture and,,A very coarse-grained (335 μm) Fe 41 Mn 25 Ni 24 Co 8 Cr 2 high-entropy alloy with a single FCC phase was cold rolling to a 80% reduction in thickness using the differential speed rolling technique with various speed ratios (SRs) ranging between 1 and 4. As the SR was increased, the volume fraction of the region of high-density micro-shear bands increased to accommodateGear Reduction in Electric Motors | Groschopp Blog,Jun 01, 2015· The “reduction” or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / 13 = 5).
Hazard Ratio - an overview | ScienceDirect Topics
The numerical value can be a fraction of 1.0 or it can be greater than 1.0. For example, a hazard ratio of 0.70 means that the study drug provides 30% risk reduction compared to the control treatment (25).
