What is a crown and pinion?
a crown and pinion is a st of gears that mesh at an angle.
Why are helical gears more favourable than spur gears?
bevel gears are used for power transmitting between the shafts which intersect at some angel ( usually right angel) , but the spur gear is used for shafts which are parallel and coplanar.
What are helicle gears?
helical gears offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix. The angled teeth engage more gradually than do spur gear teeth. This causes helical gears to run more smoothly and quietly than spur gears. Helical gears can be meshed in a parallel or crossed orientation. The former refers to when the shafts are parallel to each other; this is the most common orientation. In the latter, the shafts are non-parallel. For a crossed configuration the gears must have the same pressure angle and normal pitch, however the helix angle and handedness can be different. The relationship between the two shafts is actually defined by the helix angle(s) of the two shafts and the handedness, as defined: : : Where β is the helix angle for the gear. The crossed configuration is less mechanically sound because there is only a point contact between the gears, whereas in the parallel configuration there is a line contact. Quite commonly helical gears are used with the helix angle of one having the negative of the helix angle of the other; such a pair might also be referred to as having a right-handed helix and a left-handed helix of equal angles. The two equal but opposite angles add to zero: the angle between shafts is zero -- that is, the shafts are parallel. Where the sum or the difference (as described in the equations above) is not zero the shafts are crossed. For shafts crossed at right angles the helix angles are of the same hand because they must add to 90 degrees.
What is the significance of blood pressure ratios?
80/120mm of Hg is the normal pressure
How do you change the camera angle on gears of war 2 Xbox360?
i think there is no posibility to change it.
How do cranks work?
if you put downward pressure on the handle it causes gears to move
What is the difference between spur gears and other gears?
Spur gears are cut with straight teeth. They can only transmit rotation between parallel shafts, and are relatively economical. Bevel gears have teeth cut on an angle. They transmit rotation between non-parallel shafts. Helical gears have curved teeth. They are generally quieter than spur gears, but are generally more difficult to make and more expensive.
What are the significance of acceptance angle in fiber?
as we know that we apply light ray as source instead of electricity in case of OFC (optical fiber cable) communication but not all ray will propagate so that only those rays that have an angle greater than the critical angle can be transmitted and that reference angle is called ACCEPTANCE ANGLE.
What is significance of the study of peer pressure?
There is great significance in the study of peer pressure. This study examines the change in thought among individuals being pressured that would not normally occur.
Where are bevel gears used?
They are used when the angle of rotation needs to be changed. The rotation of a vertical rod can be changed to rotation of a horizontal rod by the use of beveled gears. <><><><><> bevel gears ARE two the wheels together or just two two wheels so pretty much you can find bevel gears in objects like .... can opener cars in a hand drill.. and many more
What is significance of solid angle?
The solid angles help us have a view of an object in three dimensions.
Can an angle stop control water flow pressure?
An angle stop is not intended to control water pressure for most applications. That being said, however, you can control the pressure with an angle stop valve (Aka angle pattern globe valve) while there is flow. As soon as the flow stops, then the pressure will equalise throughout the system. I would suggest using a PRV or pressure reducing valve. This will control water pressure under most all conditions.
