ALL ABOUT GEARS
Gears are Power transmission elements. It is the Gears
that decides the torque, speed and direction of rotation of all the
driven machine elements. Broadly speaking, Gear types may be
grouped into five major categories. They are Spur, Helical, Bevel,
Hypoid, and Worm. A lot of intricacies are there in the different
types of gears. Actually The choice of gear type is not a very easy
process. It is dependent on a number of considerations. Factors
that go into it are physical space and shaft arrangement, gear
ratio, load, accuracy and quality level.
Types of Gears
A number of gears are
manufactured using different materials and with different performance
specifications depending on the industrial application. These
gears are available in a range of capacities, sizes and speed
ratios, but the main function is to convert the input of a
prime mover into an output with high torque and low RPM. These
range of gears find use in almost every industry right from
agriculture to aerospace, from mining to paper and pulp
industry. Some of the popular types of gears in use are :Spur Gears
Spur gears are by far the most common type of gear and with the exceptions of the "cog" the type of gear that has been around the longest. Spur gears have teeth that run perpendicular to the face of the gear.
Helical Gears
Helical gears are very similar to spur gears except the teeth are not perpendicular to the face. The teeth are at an angle to the face giving helical gears more tooth contact in the same area.
Helical gears can also be used on non-parallel shafts to transmit motion. Helical gears tend to run quieter and smoother than spur gears due to the increased number of teeth in constant contact at any one period of time.
Herringbone
Gears
Herringbone
gears resemble two helical gears that have been placed
side by side. They are often referred to as "double
helicals".
One benefit of herringbone gears is that it
helps to avoid issues related to side thrust created
with the use of helical gears.
Bevel / Miter Gears
Bevel gears are used mostly in situations that require power to be transmitted at right angles (or applications that are not parallel). Bevel gears can have different angles of application but tend to be 90°.
Worm Gears
Worm gears are used to transmit power at 90° and where high reductions are required. The worm resembles a thread that rides in concaved or helical teeth.
Internal Gears
Internal gears typically resemble inverted spur gears but are occasionally cut as helical gears.
Racks
A rack is basically a straight gear used to transmit power and motion in a linear movement.
Face Gears
Face gears transmit power at (usually) right angles in a circular motion. Face gears are not very common in industrial application.
Involute Splines
Splined shafts and hubs are usually used as connectors in many different types of applications. One of the most common applications is to connect motors to gear reducers. They may also be used in transmissions.Involute splines resemble spur gears, but tend to have different pressure angles
Straight Sided
Splines
Straight sided
splines often serve the same function as involute
splines but have "straight sided" teeth instead of
involute teeth.
Sprockets
Sprockets are
used to run chains or belts. They are typically used in
conveyor systems.

working with a Vernier Caliper
Vernier calipers are a tool from the caliper family allowing users to
measure the inner or outer dimensions of items, and step or hole depths.
Created by Pierre Vernier, a French mathematician, properly-calibrated
vernier calipers hold a high degree of precision, able to measure
tolerances in 0.05mm or 0.002 inches of accuracy. Vernier calipers have
four distinct ways to measure distances.
Next, look at the marks, which are in either millimeters or fractions of an inch, along the length of the vernier scale. By eye, identify the mark on the vernier scale that lines up most accurately with the opposite mark on the main scale. This number is the rest of your measurement.
For example, if the vernier scale's zero lines up with 5.6cm on the main scale, and the 2.4-mm increment aligns most accurately with its opposite main scale mark, the final measurement will be 5.624cm.
Outer Caliper Jaws
The large outer caliper jaws at the bottom of the tool have flat faces that touch each other when the vernier caliper is in the closed position. The outer caliper jaws wrap around objects and are used to measure outside distances, such as an egg or the length of a square.Inner Caliper Jaws
The inside caliper jaws, on the top of the tool, appear as a smaller version of the outer caliper jaws. The inner caliper jaws' flat edges face away from each other when the vernier caliper is opened and are used to measure inner distances, such as the inside of a tube.Depth Probe
The depth probe is a long, flat, thin piece of metal that runs through the center of the caliper and moves out from the body of the vernier calipers when the jaws are opened. The depth probe is used to measure step or hole distances. By placing the flat end of the caliper flush against the upper face of the object being measured, then moving the caliper jaws to lower the depth probe into the object's hole, you can use the scale to read the depth of the step or hole.Main Scales
Vernier calipers have main scales running along the length of the tool. The scale along one edge of the tool is in inches, while the other side has increments in centimeters. The main scales can be used as a simple ruler.Reading a Vernier Caliper
Reading a vernier caliper is a multistep process. First, lightly place the jaws or depth probe against the object being measured. As the jaws move along the length of the caliper, a smaller scale called a vernier travels with them. The number on the main scale opposite the zero on the vernier scale is the first part of the measurement.Next, look at the marks, which are in either millimeters or fractions of an inch, along the length of the vernier scale. By eye, identify the mark on the vernier scale that lines up most accurately with the opposite mark on the main scale. This number is the rest of your measurement.
For example, if the vernier scale's zero lines up with 5.6cm on the main scale, and the 2.4-mm increment aligns most accurately with its opposite main scale mark, the final measurement will be 5.624cm.
