Gears & Gear Manufacturers
Gears are mechanical devices that transfer torque and motion or set mechanical motion in action through the engagement of other gears, a shaft or a series of parts. Gears interlock with one another and turn together with the help of evenly cut teeth. Teeth allow different sized and shaped gears to interlock with one another. Gear applications are quite diverse and highly customizable; they appear anywhere that an application requires speed reduction, speed increase, power transmission, motion transmission or force reduction. The relationship between gear size and speed is called “speed ratio,” or alternatively, “gear ratio.” Gear ratio can be calculated using a gear’s number of teeth. For example, two interlocking gears that have 60 teeth and 30 teeth, respectively, have a gear ratio of 2:1.
The world of industrial gears is quite varied. Some common ones include: spur gears, sprockets, planetary gears, bevel gears, spline gears, helical gears, rack and pinion spur gears, rear end gears, worm gears and differential gears. The spur gear, also called a straight-cut gear, is the simplest type of gear available. Straight-sided along the gear wheel’s axis, with straight teeth in line with the axis, spur gears are frequently used as sprockets. Sprockets are thin gears with easy-locking teeth that lock into roller chains, like bike gears. They’re used for non-slip pulley power transmission. Other types of spur gears transmit motion and torque laterally through compatibility with other parallel aligned gears. Such gears are main components in planetary gears. Planetary gears, also called epicyclic gear trains, are used in complex applications that require smooth torque transmission, such as drivetrains and automotive transmissions.
