Influence of the Lubricant Temperature of Splashed Lubricated Worm Gearbox on Churning Power Losses

Abstract

The primary goal of lubricating a worm gearbox is to encourage sliding between teeth, which lowers the coefficient of friction and regulates the temperature rise brought on by rolling and sliding friction. Due to both non-load-dependent and load-dependent power losses, the worm gearbox has a relatively poor efficiency. Nonetheless, to meet the needs, there is now a greater need for more efficient worm gearboxes. Lowering churning power losses, can be accomplished. Bearing friction losses and gear friction losses make up the load-dependent losses. The non-load dependent losses are the bearing churning losses, gear windage losses, gear churning losses and oil seal losses. Numerous factors, including speed, direction of rotation, oil amount, and immersion depth, affect the non-load dependent losses.Only the impact of lubricant temperature and its relationship to non-load-dependent losses will be the focus of this study. A thorough experimental investigation was conducted utilizing the direct torque measuring method. A brand-new test rig was created, assembled, and placed into service to gauge input torque in the absence of load. We kept an eye on the fluctuating impacts of lubricant temperature on churning power loss.
