Hymark/Kentucky Gauge
Single stage ratios up to 30:1 Until now, spur gears or a multistage bevel gear was required to achieve high transmission ratios, which resulted in heavier weight and larger space requirements. Graessner's high ratio hypoid gears, on the other hand, achieves high ratios in a single stage, has a lower mass and can be used in small spaces. 90% higher efficiency than a worm gear. Ratios up to 30:1. Longer life. Smoother tooth contact and engagement. More efficiency and less weight. Lower mass moment of inertia. Hymark is your...

Formulas for RF Related Conversions dBmW = dB uV  107. The constant inthe above equation is derived as follows. Power is related to voltage according to Ohm's law. The Log10 function is used for relative (dB) scales, so applying the logarithmic function to Ohm's law, simplifying, and aling by ten (for significant figures) yelds: P = V2/ R.
