A gear-reduction ratio is calculated directly from the number of teeth on each gear. The number of teeth is a simple value to obtain and that is all you need to complete this computation. After you calculate this ratio, you can use it for any other computation you -- need such as speed or torque.

A CT in which more than one ratio is obtainable by reconnection or tapings in primary or secondary windings is known as a multi-ratio instrument transformer (e.g. a CT having a ratio of 800-400-200/1 A). In such transformers, tapings in primary windings must be avoided as far as permitted by the design.

Dec 17, 2016· In primary metering, the metering is installed on the high voltage lines. Many times when referring to primary metering we are talking about distribution lines. Some common voltages for distribution lines are 12,470v and 24 kv. Since primary metering installs its equipment on the primary, the metering equipment is rated for this higher voltage.

Jan 04, 2014· The only gear that will work is one made specifically for that position in that transmission. If you are actually setting out to "measure" that gear (with a view towards making a mate from scratch), you have a very long haul in learning and doing ahead of you. Easy to measure a spur gear. Lots more complicated to measure a helical gear.

primary source of income redistribution, remains inadequate. It is widely recognised that the present growth trajectory of about 3 percent per annum: • fails to reverse the unemployment crisis in the labour market; • provides inadequate resources for the necessary expansion in social service delivery; and

A helical gear such as shown in Figure 4.7 is a cylindrical gear in which the teeth flank are helicoid. The helix anglein reference cylinder is β, and the displacement of one rotation is the lead, pz. The tooth profile of a helical gear is an involute curve from an axial view, or in the plane perpendicular to the axis. The helical gear has two ...

The gear to be inspected is mounted on one shaft while an accurate and qualified master gear is mounted on the other shaft. The pair is positioned to contact by spring loading or a similar mechanism. As the gears are rotated, tooth-to-tooth errors and runout is measured between the inspection gear and master, then these measurements are ...

Say you have an input gear with 10 teeth and an output gear with 20 teeth. You find the speed ratio by working out 20 ÷ 10 = 2. This pair of gears has a speed ration of 2, or 2/1. In other words, the input gear revolves twice to make the output gear revolve once.
