Overview
Boston Gear change gears are used primarily on machine tools to provide different cutting speeds while using a constant speed input. All Boston Gear change gears are manufactured with a double key to accept the compound steel bushings that connect two gears together, allowing them to spin on an intermediate shaft. The change gears we stock range from 20-tooth through 128-tooth gears, in one tooth increments, depending upon the diametral pitch, for a nearly infinite number of ratio possibilities. Be sure to ask for the Boston Gear compound steel bushings designed specifically for use with these gears.
Features and Benefits
With 20 to 128 teeth, our change gears offer an almost infinite number of ratio possibilities.
A PA of 14 1/2° ensures smooth, quiet operation.
These change gears are available in both steel and cast iron to suit a variety of application requirements.
Compound steel bushings specifically designed for these change gears are available to maximize performance.
Boston Gear's change gears are available via our Guaranteed Same Day Shipment Program to ensure timely delivery.
Sample Applications
