gear motorGear motors are at the heart of every mechanical system that has a life of its own. The variety and design complexity that such mechanical bodies can take in kinematics are endless: a sequence of straight cut gears, a mechanical wheel, bevel gears, helical gears, mechanical variators/ worm gears, cycloidals.

Often, in order to reach compromises in terms of efficiency, noise level and values of output torque within spaces well defined by the blueprint, the above-mentioned construction designs are combined with each other. 



The gear motor with complex tribological system 

A gear motor, being heterogeneous, represents a complex tribological system: the pressure and velocity conditions along the kinematic chain vary seamlessly, while the friction depending on the ideal form of contact between the surfaces in motion can take on a prevalent state of sliding friction or of rolling, or a state of hydrodynamic lubrication rather than mixed lubrication (Stribeck curve).

For this reason, once again, choosing the most appropriate lubricant solution becomes crucial in terms of achieving the target hours of operation predicted by the design and, especially, by the application contexts.
