what is gear racks

Gears and gear racks use rotation to transmit torque, alter speeds, and modify directions. Gears come in many different forms. Spur gears are simple, straight-toothed gears that run parallel to the axis of rotation. Helical gears have got angled teeth that steadily engage matching tooth for smooth, quiet operation. Bevel and miter gears are conical gears that operate at the right angle and transfer motion between perpendicular shafts. Modify gears maintain a particular input speed and enable different output speeds. Gears are often paired with equipment racks, which are linear, toothed bars used in rack and pinion systems. The apparatus rotates to drive the rack’s linear motion. Gear racks provide more feedback than additional steering mechanisms.
