Increasing spur gear durability: two-material spur gear
International Journal of Computer Applications in Technology, 2005A new design method to improve durability of spur gears made of low tensile strength material is utilised. In this method, the gear is made of two materials, where most of the gear body is made of low tensile strength material (like gray cast iron or aluminium), and only teeth fillets are made of high tensile strength material (like steel).

FZG gear testing is widely used to evaluate the performance of lubricants, gear materials, and gear-tooth geometries under different loads. During these tests, gear tooth wear results in the loss of gear profile in the form of micro-pitting, pitting and ...

A novel thermal network model for predicting the contact temperature of spur gears
, 2020This paper proposes a thermal network model to predict the contact temperature of spur gears. A crucial parameter in gear scuffing evaluation is the contact temperature, which comprises the bulk and flash temperatures.

Dynamic optimization of spur gears
Mechanism and Machine Theory, 2007This paper presents a global optimization method able to find gear profile modifications that minimize vibrations. A non linear dynamic model is used to study the vibrational behavior; the dynamic model is validated using data available in literature. The optimization method takes into account the influence of torque levels both on the static and the ...

Dynamic Behaviour of Spur Gears
Proceedings of the Institution of Mechanical Engineers, 1963In an earlier paper by one of the authors (9) a theoretical analysis suggested that, at certain speeds, large vibrations can occur in a pair of spur gears, without any manufacturing errors and without any external excitation, provided the damping is less than about 0·07 of critical.
