Speed Reducer, also known as gear heads or gearboxes, contain a set of gears, and input and output shafts. Speed Reducers are called a gear head when it is mounted directly onto a motor, not just a shaft. During equipment operation, the motor transmits power to the input shaft of the reducer. The speed reducer then converts this power into lower output speed, which the reducer transmits to the connected load through the output shaft.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"left\"\u003e\u003cspan\u003eSpeed Reducers are utilized by a wide variety of industries. Common industries in which reducers are found include the materials handling; automotive; aerospace; recreational; construction; food and beverage processing; oil and gas; and textile industries. Reducers are used in a variety of applications, including automation equipment; conveyors; compressors; printing presses; pumps; compressors; generators; and robotics applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"left\"\u003e\u003cspan\u003eThe formation of the gears in Speed Reducers are available in many manifestations. Each one is designed for specific load and torque capacities. An example is a cycloidal reducer, which is capable of providing high reduction ratios with high accuracy, with the use of rolling elements. Another formation is that of the planetary reducer, which handles large shock loads well. The name stems from a likeness to a solar system in which \"planet\" gears revolve around a \"sun\" gear.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"left\"\u003e\u003cspan\u003eSpeed reducers are advantageous in many pieces of equipment.
