Advantages and disadvantages of common mechanical transmission devices As a national high-tech enterprise engaged in testing equipment such as packaging industry, home furnishing industry, material mechanics, optical measurement, environmental reliability testing, etc., the precise data of the instrument cannot be separated from the precise transmission method. The common mechanical transmission of Haida testing instruments are mainly divided into three categories: belt drive/chain drive/gear drive. The following is a brief description of its advantages and disadvantages based on my several years of assembly and design experience. 1. Belt drive (synchronous wheel + synchronous belt) Advantages: ① The synchronous belt itself is elastic, shock absorption, stable transmission, and low noise; ②The principle is simple, easy to install and easy to maintain. Disadvantages: ①The timing belt is easy to wear; ②It is not suitable for high temperature and flam

environment. 2. Chain drive (sprocket + chain) Advantages: 1 The tension force can be adjusted to be small, so the pressing force is small, and the shaft deformation is small; 2 The mechanism is stable and durable, and can work in high temperature, dusty and corrosive environments. Disadvantages: ①The instantaneous transmission ratio is not constant; ②It is not suitable for rapid reversal mechanism. 3. Gear transmission (gear + gear) Advantages: ①High transmission ratio efficiency; ②Compact and reliable structure. Disadvantages: 1 high manufacturing cost; 2 not suitable for long-distance sh
