Martin Sprocket & Gear

QD (quick detachable)is a sprocket where a tapered bushing is bolted into the taper bore that is machined in the sprocket. When installed this bushing is compressed onto the shaft providing a tight grip.

A plates are flat sprockets with no hub extension on either side. They can be altered for your application with bolt holes, custom bores, hardened teeth or special hubs welded to them.

Hi-Cap® sheaves (narrow V-belts) are manufactured from class 30 gray iron (30,000 tensile strength) and can have a maximum speed of 6500 fpm. All Martin sheaves are statically balanced. Dynamic balancing should be considered for any sheaves exceeding 5000 fpm, or if they will be used on equipment where vibration is a problem. Martin has extensive inventories of both QD and TB style V-belt sheaves to run with 3V, 5V, and 8V belts.

Martin Quadra-Flex® is a proven design which offers long life, torsional flexibility, ease of installation and withstands misalignment, shock and vibration. TPR, EPDM, Neoprene and Hytrel® sleeves are available in solid, split and semi-split construction.

QD (quick detachable) bushings are designed for conventional mounting or reverse mounting. These bushings have a flange.

Shear pin sprockets provide simple, dependable protection against expensive machinery damage caused by overloads or jamming. Torque is transmitted by a single pin, necked to shear when the safe load is exceeded. When an overload occurs the pin shears, disconnecting the drive immediately. Shear pins can be necked to customer specific torque ratings.

Worms and worm gears are used to power right angle, non-intersecting shafts. In normal applications the worm gear is driven by the worm. The most popular use of worms and worm gears is in applications where high ratio speed reduction is desired in a relatively limited space. They are also used in applications where high resistance to the worm gear shaft reversing and driving back through the worm is desired.
