higher ratios for dynamic oil gearbox

dynamic oil gearbox ,the maximum torque, speeds, and radial loads published cannot be used simultaneously. Proper service factors must be applied to accommodate a wide range of dynamic applications. And, once the appropriate speed reducer is selected, proper installation and maintenance are the keys to maximizing life.

Paper mill gearbox offer compact designs in higher ratios, while helical and spur reducers are generally the most economical. All are fairly efficient.

Working principle

The paper mill gearbox mainly consists of gear and shaft, which can produce variable speed torque through different gear combination. The automatic gearbox AT is composed of hydraulic torsion device, planetary gear and hydraulic control system, and the speed change torque is achieved through hydraulic transmission and gear combination.
The hydraulic torque converter is the most characteristic of the unit, which consists of the pump wheel, turbine and guide wheel, and directly input the engine power transmission torque and clutch. Pump wheel and turbine is a pair of work, as if they are relatively placed two fan, a fan blowing out of the wind will drive the other passive fan blade rotation, the flow of air, wind power into kinetic energy transfer medium.

B Helical Bevel Gearbox

B helical bevel Gear Units is a brand-new model of rigid tooth flank gear reducers with wide application areas,which has the feature of large torque range, a design of unit structure modulization capable of horizontal mountingand vertical mounting, three kinds of output shafts --- solid shaft, hollow shaft and hollow shaft with shrink disk. 

With carbureted high-strength good-quality alloy, the series has the feature of high-efficiency and long life-span, high permissible axial and radial loads, low noise, high reliability and compact structure and so on.
