The Self-Compensation Approach for Backlash on Gear Train

Abstract

Even if rotates unidirectional or bidirectional, a certain amount of space (free angular movement usually called “backlash”) between meshing teeth flanks are allowed for functional reasons. The actual value and effects of the mechanical clearance that is critical in the mesh condition of gears have been a subject to be investigated by gear engineers. The actual backlash stems from time-varying backlash and constant backlash. User friendly software has been developed in MATLAB, to guide assembly personnel/staff to create a combination of different gearbox components from the measurement data bank to obtain a specified backlash range for three gear train. Provided that, different gearboxes with different backlash values/ranges will be assembled by using manufactured and measured components. Unless out of design limits, almost no component will be wasted. This condition will also avoid any slowing of manufacturing and helping to increase production capacity. In the present paper, operating behaviour of system is evaluated in terms of backlash also the automatically self-compensation of sources of backlash methodology is applied to three gear train for backlash parameter.
