Design Units
|
|
|
| |
Your choices are...
|
|
|
| |
English
|
|
English gears use design units such as inches and fractions of inches; they also employ diametral pitch (DP) or circular pitch (CP) as tooth pitch designations.
|
| |
Metric
|
|
Metric gears are made with design units of millimeters (mm), and the pitch is designated as a module, or metric distance between teeth.

Pressure Angle:
|
|
Pressure angle is the angle between the line of force or action and the tangent to the pitch circle at the point of mesh. The most common pressure angles for gears are 14.5° and 20°, while some worms and worm gears utilize a 25° pressure angle. Gears must have the same pressure angle to mesh.

| |
Anti-backlash
|
|
Anti-backlash gears have a mechanical assist such as a spring to take up any play between meshing gear teeth, thus avoiding backlash when gear direction changes.
|
| |
Ground Teeth
|
|
Ground teeth provide smoother, higher-precision tooth form.
|
| |
Integral Rack and Rail
|
|

Metal:
|
|
|
| |
Your choices are...
|
|
|
| |
Aluminum
|
|
A bluish silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. Lighter and less strong than steel.
|
| |
Brass
|
|
Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.
|
| |
Bronze
|
|
Bronze is a copper base alloy metal composed of copper as the main alloying metal and one or more other metals, such as tin, zinc, or phosphorus. Silicon bronze is one typical bronze alloy.
|
| |
Cast Iron
|
|
Cast iron is a very durable iron alloy with high amounts of carbon. This category includes ductile iron, gray iron and white cast iron grades. Differences in grades are due to variations in composition and processing.
|
| |
Carbon / Alloy Steel
|
|
A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. Many grades of carbon and alloy steel are used as fastener materials; may require coating to protect against corrosion.
|
| |
Hardened Steel
|
|
Steel may be hardened in a number of ways, including a variety of quenching techniques in oil and water, being passed through induction chambers, etc. Quickly cooling steel during processing freezes, traps and packs the carbon atoms inside the shrunken iron crystals, thereby producing a very hard and brittle metal. Although very hard, it cannot absorb much shock or impact without breaking.
|
| |
Stainless Steel
|
|
Stainless steel is chemical and corrosion resistant and can have relatively high stress ratings. Many grades used in fasteners; often does not require anti-corrosion coating, but most stainless steels cannot be hardened to the same degree as carbon steels.
|
| |
Other Metal
|
|
Unlisted, specialized, or proprietary metal or alloy.

|
| |
Nylon
|
|
Nylon, comprising several grades of polyamides, is a general-purpose material in wide use; it is tough and resistant and has good pressure ratings.
|
| |
Polycarbonate
|
|
Polycarbonate is an extremely tough polymer that can be machined to close tolerances. Lubrication is sometimes needed, as the wear properties of polycarbonate are not as good as some other polymers.
|
| |
Other Plastic
|
|
Unlisted or specialized polymer or plastic material.

|
|
|
| |
Hubless
|
|
No mounting hub.
|
| |
Hub
|
|
Hub is an extension of the gear body which allows shaft mounting options.
|
| |
Keyway
|
|
One or more square-edged cutouts designed to mate with a shaft key.
|
| |
Set Screw(s)
|
|
Screws tighten directly onto shaft for gear attachment.
|
| |
Hub Clamping Screw
|
|
Gear is attached via a screw that squeezes the inner diameter of the hub to a tight fit around the shaft.
|
| |
Split (Requires Clamp)
|
|
Hub is split into several pieces, which are tightened down by a separate clamp to grip shaft.
|
| |
Simple Bore
|
|
Typically for press-fit or adhesive attachment.
|
| |
Other
|
|
These may include specific proprietary or special shaft attachment mechanisms.
