A gear is a rotating machine part that precision worm gear utilizes cut tooth, or cogs, to mesh with another toothed part-usually another gear or a linear toothed component (called a equipment rack)-to transmit rotational motion and torque. By using a mixture of precision gears with the correct ratio, the rate, torque, and even path of 
a power supply can be changed. Two or more gears working collectively, called a gear train or a transmitting, will more often than not create a transformation in torque. If one equipment is larger than the other, a mechanical advantage is produced; the rotational velocity and torque of the particular gears differs in proportion to their diameters.
HZPT is a leading manufacturer of precision gears for all applications. We offer precision gears in regular and custom inch-measure sizes and a number 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 type of precision gears in metric sizes.
