Considering the microstructure of tooth surface and the dynamic characteristics of the vibration responses, a compound dynamic backlash model is employed for the gear transmission system. Based on the fractal theory and dynamic center distance, respectively, the dynamic backlash is presented, and the potential energy method is applied to compute the timevarying meshing stiffness, including ...

The mounting distance in gears for intersectedaxes gear pairs, as well as for crossedaxes gear pairs, is a design parameter that cannot be inspected directly, as the base cone apex of the gear does not exist physically. This is the root cause for the significant inconveniences when inspecting the accuracy of the mounting distance.

The term "backlash" can also be used to refer to the size of the gap, not just the phenomenon it causes; thus, one could speak of a pair of gears as having, for example, " mm of backlash." A pair of gears could be designed to have zero backlash, but this would presuppose perfection in manufacturing, uniform thermal expansion characteristics ...

If the teeth are not machined by tooth cutters, and the teeth profiles are still kept intact, then the 2 gears will get jammed in formula for calculating the minimum teeth number without undercutting is:z min =2ha*/sin 2 αWhen ha*=1, and α=20°,we will have the z min =2*1/(sin20°） 2 ==17（always round down）. So, the minimum teeth number for standard gears is 17.

βy = tan − 1(dytanβ d) For the geometry of a helical gear, the helix angle varies as a function of radius. This is observed in a helical gear tooth since the involute profile spans over a range of diameters. This results in the helix angle at the base diameter being less than at the tip diameter.
