With the wide application of planetary gear reducers in industry, many people cannot distinguish them from gear reducers. Next, the editor will introduce the differences between the two speed reducers.
1. Gear reducer
The gear reducer is an external meshing involute spiral cylindrical gear reducer produced according to ZBJ19004. Its main structure consists of a transmission shaft, a spur gear, and a motor. The internal structure is mainly composed of multi-level gears, which is simpler than a planetary reducer. The working principle of a gear reducer is that the motor provides rotational speed, and the transmission shaft connects the motor and the gear reducer. The internal structure of a gear reducer consists of multi-level gears, each stage of which is meshed and driven by multiple gears of different sizes, forming a reduction ratio and transmission ratio. At the same time, the output speed also reduces and improves the torque, achieving the desired transmission effect; The more gears in the gearbox, the slower the rotational speed, the greater the torque, and the stronger the load carrying capacity. The disadvantage is that the greater the noise; When designing a gear reducer, the power demand mode is basically customized, which means that the speed, torque, and other parameters of the gear reducer are customized according to needs.
2. Planetary reducer
The planetary gear reducer is expanded and optimized on the planetary gear reducer, also known as the planetary gear reducer, which also has a gearbox structure inside; The main transmission structure of the reducer consists of sun gear, planetary gear, outer gear ring, planetary carrier, sealing ring, and transmission bearing. Compared with gear reducers, its manufacturing process is more complex, performance is better, and transmission is more reliable. The working principle is similar, but there are two properties that gear reducers cannot achieve, such as "power splitting" and "multi tooth meshing.". These two characteristics are commonly used for transmission gearboxes and clutches. In addition, planetary gear reducers are military grade reducers, but the price is industrial and widely used in industrial equipment manufacturing.
