The shaft mounted gear reducer is a transmission device that integrates the reduction gearbox with the input shaft and output shaft. With its compact structure and direct installation characteristics, it occupies an important position in the industrial transmission system. Its design concept focuses on simplifying the installation process and improving space utilization.
From a structural point of view, it eliminates the independent machine base of the traditional reducer. The output shaft is directly connected to the input shaft of the working machine and fixed by a clamping sleeve or a flange. The overall volume is more than 30% smaller than the horizontal reducer of the same power. The internal transmission adopts helical gears or hardened gears, with a transmission efficiency of 94%-97%, and a speed ratio range of 5:1 to 100:1, which can be adapted to different speed requirements.
Easy installation is its core advantage. There is no need to adjust the coaxiality of the input shaft and the output shaft. Fixing can be completed through key connection or expansion sleeve. The installation time is only 1/3 of that of traditional reducers. It is especially suitable for working conditions with narrow space, such as conveyors, mixing equipment, etc. At the same time, the built-in backstop can prevent the load inertia from reversing and improve operational safety.
It has a wide range of applications and is frequently used in industries such as mining, building materials, and grain processing. When driving a belt conveyor, it can withstand large radial loads; when used with a stirring blade, the hardened tooth surface design can cope with material impact. Its sealing structure adopts double-lip oil seal with protection grade up to IP54, which can adapt to harsh environments such as dust and moisture.
When selecting a model, you need to pay attention to the rated power (0.75kW-160kW), output torque and installation method, and match the model based on the load characteristics. The shaft mounted gear reducer is an ideal choice for simplifying system design and reducing operation and maintenance costs in industrial transmission due to its high efficiency, compactness and easy installation.
