standard spur gear sizes

Metric Spur Gear Rack. Metric gear rack is classified into nine different size modules (1 - 8) and are constructed of C1045 steel that meets UNI-EN10083-1 specifications. Our metric spur gear racks are suitable for continuous mounting and have a high precision tolerance of 0/-20μm on a single pitch and 0/- 30μmm on 500mm length sum of pitches.

Transmitting power between parallel axes, the teeth project radially on the disc. The sole variance in their identity remains the rack, which is covered more in-depth in Engineering360's Rack and Pinion Specification Guide. Spur gears are regularly used for speed reduction or increase, torque multiplication, resolution and accuracy enhancement

2.5 Pitch And Module Essential to prescri gear geometry is the size, or spacing of the teeth along the pitch circle. This is termed pitch, and there are two basic forms. Circular pitch — A naturally conceived linear measure along the pitch circle of the tooth spacing.

Standard Gears – 16 to 96 Pitch “Pitch diameter” is the theoretical diameter at which the gears contact each other to transmit motion.

Spur gear can be classified into two pressure angles, 20° being the current industry standard and 14½° being the former (often found in older equipment).

This Standard sets forth methods to be followed for specifying drawing data for gears operating on axes which are parallel. It is the purpose of this Standard to provide formats, nomenclature, and definitions for the following types of gears: Spur, Helical, Double-Helical, and Spur and Helical Racks. The minimum data for the various gear types

Standard metric spur gears are 14.5° or 20° pressure angled. Root Diameter: The distance from the bottom of one tooth to the bottom of a tooth opposite measured through the axis of the gear.
