About Industrial Gears
Industrial gears are devices, used in conjunction with
other gears and parts, that engage motion and/or transfer power and motion
through a product or series of parts. Industrial gears consist of an
object, usually cylindrical, with a toothed perimeter. This turns in
concurrence with a matching toothed part. The intersecting points of
these teeth transfer the motion/power from one to the other. Industrial
gears are involved in the mechanics and workings of anything that has
an engine or motor producing rotational motion. The top four sectors
of clients for industrial gear manufacturers are industrial, marine,
aerospace and automotive, which is the largest.
Industrial gear manufacturers specifically design their products to withstand
harsh and repetitive use. Important components with industrial gears
are the teeth and the ratio. These two factors determine the function,
speed and control offered with the pairing of industrial gear pieces.
The key to selecting the appropriate industrial gears for any purpose
revolves around the size, material make-up and ratio of the gear. These
factors will determine gear’s durability and strength, and also
the speed it will be able to engage.
When searching for industrial gears, the size specifications that should
be consider are number of teeth, pitch diameter, face width and length.
The pitch of the industrial gears is determined by the number of teeth
and the preferred pitch diameter. Another important factor is materials
of construction, with there being a variety to consider and all with
different properties. Contributing to optimal performance of industrial
gears materials are design life, power transmission requirements, noise,
heat generation and presence of corrosive elements. The wide assortment
of industrial gears include aluminum gears, brass gears, bronze gears,
cast iron gears, steel gears, hardened steel gears and stainless steel
gears, plastic gears, acetal gears, Delrin® gears, nylon gears and
polycarbonate gears. Industrial gears may also be made with a combination
of metal and plastic with the teeth being plastic and the inserts being
metal. Consulting with industrial gear manufacturers for a specific application
is best for deciding on construction material.
Production of industrial gears may be segmented into several dimensions,
but the most common are open industrial gears or loose industrial gears
and enclosed drive industrial gears manufacturers. Open industrial gears
or loose industrial gears are usually produced in pairs consisting of
the industrial gear and pinion. Industrial gears are produced by contract
machine shops to certain specifications and standards that are set by
the customers. Most of these manufacturers do not produce for their own
industrial gears. Enclosed drive manufacturers supply complete assemblies,
which an OEM (original equipment manufacturer) installs into the final
industrial gear product.

Types of Industrial Gears
- are intended to operate on axes that
intersect, usually at a 90 degree angle, to work around corners.
- link two shafts through a covering, forcing the
total of the rotational angles of the shafts to be the same as the
rotational angle of the covering.
- have angled teeth to create a thrust load on the gears
when they mesh. Car transmissions often have these types of gears.
-
conduct power and motion between non-intersecting, parallel axes that
may or may not have a center groove, with each tooth making two opposite
helices.
-
are similar to bevel gears but differ in the design to operate on non-intersecting
axes.
- are defined by the length in millimeters of the pitch
circle diameter per tooth.
- are
bevel gears put together with equal numbers of teeth and axes that are
usually at right angles.
- are a set of gears usually
two or more on or inside a larger gear. They make drastic gear
ratios possible.
-
are gears made primarily of plastic, sometimes with both metal and plastic
components. These gears are generally cost effective and light; some
are
Injection Molded plastic gears.
-
are similar to helical gears and have a higher potential load transmission
compared to straight bevel gears, which is achieved by cutting the teeth
in a curved shape.
- contain a series of ridges on a driveshaft that even out rotation speed of the companion piece.
- are gears with metal teeth that enmesh with chains.
- are cylinder shaped gears that have both straight and
parallel teeth and work on parallel axes.
-
have straight teeth that radiate from the center point of the gear.
- have a curved and
recessed throat that gives the worm access to the gear teeth. Usually
they are made of bronze,
iron or steel.
