High-torque single-screw gearboxes are often used and are important mechanical components whose primary function is to transfer the generated power to the motor and get the corresponding speed. In the use of high-torque single-screw gearboxes, it is necessary to match the appropriate lubricants in order to achieve better efficiency and improve the operating life.
Generally, gears of high-torque single-screw gearboxes can be lubricated with thin oil, dry oil, and solids, but they are used when the line speed of the gears is not too high; the lubrication of the bearings is usually dry oil lubrication. Most high-torque single-screw gearboxes are closed-type drives and gears and bearings are typically lubricated with thin oil.
When the linear speed of the high-torque single-screw gearbox gear is greater than 12-14 meters per second, an external circulation is required at this time. The external circulation is to pump oil to the gears and bearings by the oil pump, so that not only the lubrication function but also the cooling The role plays an important role in improving the reliability of the high-torque single-screw gearbox.
