A equipment is a rotating machine part that utilizes cut tooth, or cogs, to mesh with another toothed precision worm gear part-usually another gear or a linear toothed part (called a gear rack)-to transmit rotational motion and torque. By utilizing a combination of precision gears with the correct ratio, the velocity, torque, and even direction of a power supply can be changed. Several gears working collectively, called a gear train or a transmission, will almost always 
create a modification in torque. If one equipment is larger than the other, a mechanical benefit is created; the rotational quickness and torque of the respective gears differs compared to their diameters.
HZPT is a respected manufacturer of precision gears for all applications. We provide precision gears in regular and custom made inch-measure sizes and a variety of configurations, including spur gears, anti-backlash gears, worm gears, helical gears, bevel gears, miter gears, pinion gears, and more.
We also provide a full line of precision gears in metric sizes.
