A gear is a rotating machine component that utilizes cut tooth, or cogs, to mesh with another toothed part-usually another gear or a linear toothed component (called a gear rack)-to transmit rotational movement and torque. By utilizing a mixture of precision gears with the right ratio, the speed, torque, and even path of a power source can be changed. Several gears working together, called a gear teach or a transmitting, will almost always create a switch in torque. If one gear is bigger than the various other, a mechanical benefit is created; the rotational swiftness and precision worm gear torque of the respective 
gears differs in proportion to their diameters.
HZPT is a leading manufacturer of precision gears for all applications. We offer precision gears in standard 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 provide a full type of precision gears in metric sizes.
