A gear is a rotating machine part that 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 movement and torque. By 
utilizing a precision worm gear mixture of precision gears with the right ratio, the quickness, torque, and even path of a power supply can be changed. Two or more gears working collectively, called a gear teach or a transmitting, will more often than not create a change in torque. If one equipment is larger than the other, a mechanical advantage is created; the rotational swiftness and torque of the respective gears differs in proportion to their diameters.
HZPT is a leading producer of precision gears for all applications. We offer precision gears in regular and custom made 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 offer a full type of precision gears in metric sizes.
