1.Every so often I find that I need to make up "yet another" HF helical whip antennafor mobile or portable operation There aren't too many online calculators that will allow you to readily design your own whip to your parameters : frequency, length and effective diameter of the former

2.This section introduces the dimension calculations for spur gears, helical gears, gear rack, bevel gears, screw gears, and worm gear pairs Calculations of external dimensions eg Tip diameter are necessary for processing the gear blanks Tooth dimensionssuch as root diameter or tooth depth are considered when gear cutting

3.Can someone help me understand if it is possible to use a screw conveyor instead of a slurry pump to discharge material to a distance of 20m Our company has a screw conveyor of 15m long of size 12" and material is caustic sludge

4.The introduction starts with basic features and components of helical piles The reason for all the different terms, such as "helical pier," "helix pier," "screw pile," "torque anchor," and others, is explained through a discussion of terminology

5.The curved arc length of a helical item, used for a number of applications such as handrails, stair stringers, and helical strakes can be quickly calculated using some simple formulas We need to know the circumference equation and the Pythagorean Theorem for calculating the hypotenuse of a triangle:

6.This is the quantity of helical entries along the length of the screws Most screws have only 1 but a thread with multiple starts advance a greater distance for each turn Most screws have only 1 but a thread with multiple starts advance a greater distance for each turn

7.A helix h i l k s , plural helixes or helices h l s i z , is a type of smooth space curve, ie a curve in threedimensional space It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis

8.ball acme lead screw technical information This section will introduce most of the more common types of drive mechanisms found in linear motion machinery Ideally, a drive system should not support any loads, with all the loads being handled by a bearing system
