"Transmission element factor", also called fz, is a constant that is used to describe the friction between two elements. ie. chain and sprocket, v-belt and pulley etc.
If you have a motor that develops 100 in-lbs of torque @1750rpm coupled to a speed reducer with a ratio of 100:1 you will have...
Hmmm usually it's the other way around. The worm has the angle and the wheel teeth are at 90 degrees. It's this relationship that causes the sliding motion when the rotating worm pushes the wheel. Think of a jar lid. As for only one tooth in contact with the worm, well that's a first for me, the...
What you see as a bronze coating is actually a bronze wheel. The reason bronze is used is to reduce friction between the worm and the wheel. Unlike helical bevel gear sets which operate with a rolling action, worm gear sets operate with a sliding action that causes friction. Efficiency ranges...
Metman I think that you are forgetting the reason a worm unit uses a brass alloy worm to begin with. The ineficientcies of this type of reducer require that one gear in the set must be softer than the other. Eg. a 20:1 ratio with an 1150rpm input speed has an efficiency of 80%. Where do you...
This may be a stupid answer, but has the oil grade and oil level been checked? Usually a 460 grade of oil is used in a worm unit. Oil level is also important, too much is not better than the right amount. What is the mounting position of the unit? This will have to be taken into consideration...
Also the main concern as a greenhouse gas contributor is the agriculture industry, the reason being that they use N based fertilizers and that the Nitrogen reacts with the bacteria in the soil to produce N2O. I have come across some reports that Nitric Acid plants also cause N2O to be released...
Here is BC Hydro's explanaition and Power Factor surcharges. This is probably as clear an explanation as you will find.
There are also some very interesting Technical Guides with tips on reducing your plants power consuption.

My understanding of "Stacks" have been that they are used to raise the exhaust gases to a higher altitude, thereby allowing these gases to dissipitate easier into the atmosphere. This was an old trick used by industries to dissipitae SO2 into the atmosphere rather than in the local...
In my case I am neither an Engineer nor a Technician but both of these groups come to me continuously for advice. What I do is sell process instrumentation, my purpose in the scheme of things is to effectively provide the best solution possible for their applications. What is most important for...
Another reason would be if you had a mix of transmitters with full wave and half wave rectified power supplies on the same AC line. You would want to isolate the full wave from the half wave units. This doesn't really apply to your application but thought I would mention it from a past...
