ESSENTIAL KNOWLEDGE FOR PRODUCT DESIGN: FROM MECHANISMS TO TYPES AND SELECTION METHODS\" width=\"540\" height=\"304\" \/><\/p>\n<p>A gear reducer is a device that uses mechanisms such as gears to reduce the rotational speed of a motor and increase torque (rotational force). Since rotational speed and torque are inversely proportional, reducing the speed allows for the generation of greater force.<\/p>\n<p><strong>Contents of this section<\/strong><\/p>\n<ul>\n<li>Basic Structure and Operating Principles of Reducers<\/li>\n<li>The Relationship Between Reduction Ratio and Torque<\/li>\n<li>Limitations of a Motor Alone and the Need for a Gear Reducer<\/li>\n<\/ul>\n<p>This principle is the same as that of a bicycle\u2019s gear system: a heavy gear allows for faster riding but makes it difficult to climb hills, while a light gear reduces speed but enables climbing hills with greater force. Attempting to achieve high torque with a motor alone requires a larger unit, but by combining it with a reduction gear, even a small motor can provide the necessary torque, enabling smaller equipment, lower power consumption, and precise positioning control.<\/p>\n<p>&nbsp;<\/p>\n<h3 style=\"color: #fff; background: #c3effa; line-height: 20px; font-size: 23px; margin: 10; padding-left: 1em; padding: 1em;\"><span style=\"color: #000000; font-size: 18pt;\">Basic Structure and Operating Principle of Gearboxes<\/span><\/h3>\n<p>The most basic structure of a reduction gear consists of two gears with different numbers of teeth. When power is transmitted from the smaller gear (input side) to the larger gear (output side), the rotational speed is reduced in proportion to the ratio of the number of teeth.<\/p>\n<p>For example, if the input gear has 10 teeth and the output gear has 50 teeth, the reduction ratio is 5:1. While the rotational speed is reduced to 1\/5, the torque increases approximately fivefold. This mechanical principle of gearing makes it possible to obtain a large output from a small input. By combining multiple stages of gears, even higher reduction ratios can be achieved, allowing for the design of an optimal balance between torque and rotational speed tailored to the specific application.<\/p>\n<div>\n<div>\n<p>&nbsp;<\/p>\n<\/div>\n<div>\n<h3 style=\"color: #fff; background: #c3effa; line-height: 20px; font-size: 23px; margin: 10; padding-left: 1em; padding: 1em;\"><span style=\"color: #000000; font-size: 18pt;\">The Relationship Between Reduction Ratio and Torque<\/span><\/h3>\n<\/div>\n<div>\n<p>\u00a0The<a href=\"https:\/\/cik-ele.com\/en\/column\/motor-output\/\"> reduction ratio<\/a> is a numerical value representing the ratio of the output shaft\u2019s rotational speed to that of the input shaft. The higher the reduction ratio, the slower the rotational speed and the greater the torque. However, the actual output torque obtained is the product of the reduction ratio and the transmission efficiency.<\/p>\n<p>The transmission efficiency of gear reducers varies by manufacturer and specifications, but is typically around 95\u201398% for spur gears and 96\u201398% for planetary gears.Efficiency decreases as the number of reduction stages increases. For example, in a reducer with a reduction ratio of 10:1 and a transmission efficiency of 95%, if the motor torque is 0.1 Nm, the output torque is approximately 0.95 Nm (0.1 \u00d7 10 \u00d7 0.95). Selecting the appropriate reduction ratio for the application is key to maximizing the performance of the equipment.<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<div>\n<h3 style=\"color: #fff; background: #c3effa; line-height: 20px; font-size: 23px; margin: 10; padding-left: 1em; padding: 1em;\"><span style=\"color: #000000; font-size: 18pt;\">Limitations of the Motor Alone and the Need for a Gearbox<\/span><\/h3>\n<\/div>\n<div>\n<p>\u00a0Attempting to achieve high torque with a motor alone requires making the motor itself larger, which leads to problems such as increased weight, higher power consumption, and rising costs.
