What - No Gearbox?

摘要

Until fairly recently there have been two main methods of obtaining high torque on low speed drive applications. The first and most generally-accepted solution is the traditional electro-mechanical drive using an electric motor, fluid coupling and a reduction gearbox. The second method is to use a hydraulic motor that comes in either a medium or a low speed version. However, to achieve a specific low speed reduction with either of these options still requires a reduction gearbox which often counteracts the advantages that hydraulic drives present in terms of compactness, especially on applications such as conveyor belts where the optimum high torque is required at very low speeds.
