Trogetec, Inc. (Trochoidal Gear Technologies), of Riverton, Wyoming, offers epitrochoidal stock spur gears in miniature to large sizes. Innovative and cost-effective, two-tooth spur gears operate in an internal gearmesh engagement with two to three cylindrical teeth of four-roller (four-pin) followers of 2:1 ratio gear reducers of either the planocentric cyclo or the parallel shaft design types. Single-station cardioid indexers for excellent full-turn output motion are ideal for applications in packaging, automation, and other uses requiring compactness, smooth and quiet operation, high-load and high operating-speed capabilities, and long, maintenance-free service life. The gears are available in various metals and engineering thermoplastics. Fabrication to tooling tolerances of +/-0.0003" (0.0127 mm) or less is optional for the gears and followers.

Trogetec also handles eccentric shaft design and manufacturing. Eccentric and crank shafts are important components in cycloidal gear drives and indexers, planetary and cyclo-type speed reducers, and many other mechanisms. The technical staff of Trogetec has earned top awards and recognition for its practical design and fabrication of eccentric and crank shafts of miniature to large sizes, in prototype to production quantities, for everyday and unusual engineering requirements.

Trogetec also offers one-tooth gears for speed reducers, gear indexers, and other applications. One-lobe prolate epitrochoidal gears are in constant full-conjugacy (full-mesh) internal gearmesh engagement with two corresponding cylindrical rollers or pins of respective follower wheels. The main advantages of the new gear design include: smooth and quiet operation, because the rollers never lose driving contact with the gear; large-size rollers and lo be for strength in high-load carrying capability can be realized in miniature to large size applications, which include 2:1 ratio speed reducers and one-station cardioid drive indexing of highly favorable motion characteristics, and; the two-lobe and other epitrochoidal gear design schemes represent a logical extension of the one-lobe gear design focused on above. Fabrication to tooling tolerances of +/-0.0003" (0.0127 mm) or less is optional for the gears and followers.
