Gears are a distinct category of mechanical components in the form of toothed wheels. They are the primary elements of gear transmissions. The teeth on the surface of a gear mesh with the teeth of other gears to ensure efficient transmission of rotational motion and torque between different shafts. Gears are widely used in machinery and industrial equipment to change speed, torque, or the direction of motion in various mechanisms.
The manufacturing company New Standard specializes in custom gear manufacturing based on the customer’s individual drawings, sketches, and samples.
Gear Classification
- By the relative arrangement of shaft axes — gears with parallel axes (cylindrical gears and internal gears), intersecting axes (bevel gears), and crossed axes (worm and screw gears);
- By tooth profile shape — involute, circular, cycloidal, and eccentric-cycloidal gear models;
- By tooth arrangement — in spur gears, the teeth are parallel to the shaft axis; in helical gears, the teeth are inclined relative to the shaft axis; in herringbone gears, the teeth have a V-shaped form; in circular-tooth gears, the tooth line forms a circle;
- By the shape of the axoid surfaces — gears may be cylindrical, conical, or hyperboloidal;
- By functional purpose — sector gears and gear racks;
- By level of protection — open and enclosed gears.
Materials for Manufacturing Metal Gears
- Carbon and alloy steels with chromium, nickel, and vanadium additives to provide increased mechanical strength and wear resistance;
- Cast iron — characterized by good strength and relatively low cost, but with lower wear resistance compared to steel;
- Bronze — offers high wear resistance and excellent corrosion resistance; commonly used in river and marine transport, as well as for gears operating under high-temperature conditions;
- Brass — an inexpensive copper–zinc alloy that is easy to machine and is most often used for gears operating under low loads;
- Aluminum alloys — used for manufacturing lightweight gears.
As for non-metallic materials, polyamide (nylon) or caprolon, textolite, PTFE (polytetrafluoroethylene), and polyacetal are most commonly used in gear manufacturing. The choice of material should be based on the load level and the required noise level during operation. For gears operating under high loads, steel alloys with additional heat treatment are used; for low-load applications, aluminum alloys, bronze, cast iron, and polymer materials are applied; and for operating conditions requiring low noise levels, plastic materials are most often used.
Custom Gear Manufacturing
New Standard manufactures parts and metal products based on individual projects and the customer’s engineering documentation. Production is carried out using CNC equipment with the involvement of qualified technical specialists and design engineers.
The cost of custom gear manufacturing is determined based on the design and technological complexity of the product, the material used, the quantity of units, and the agreed production lead time. To prepare an accurate quotation, the customer needs to contact the company by phone or email and provide the initial technical data.
