“…Here, the novelty of the research lies in numerically predicted values of the J-integral taken as a measure of the crack driving force for steels 1.7147 and 1.4762 which are, according to the authors' knowledge, unavailable to construction designers in the presented form. Both materials offer improved corrosion resistance and can be considered for engineering applications intended to be used in corrosive environment and susceptible to crack growth and fracture like spiral bevel gears in truck differential systems prone to failure (Sekercioglu and Kovan, 2007) or stainless steel tubes found in recuperators and exposed to elevated temperatures that cause failures (Bhattacharyya et al, 2008). The results of the investigation presented in this paper can be used to avoid such failure scenarios.…”

Fracture behavior of two types of steel (1.4762 and 1.7147) is compared based on their numerically obtained J-integral values. The J-integral are chosen to quantify the crack driving force using the finite element (FE) stress analysis applied to single-edge notched bend (SENB) and compact tensile (CT) type fracture specimens. The resulting J-values are plotted for growing crack length (∆a -crack length extension) at different a/W ratios (a/W -relative crack length; 0.25, 0.5, 0.75). Slightly higher resulting values of the J-integral for 1.4762 than 1.7147 can be noticed. Also, higher a/W ratios correspond to lower J-integral values of the materials and vice versa. J-integral values obtained by using the FE model of the CT specimen give somewhat conservative results when compared with those obtained by the FE model of the SENB specimen.

“…• Optimisation of the geometry of bevel gears, optimisation of the conditions of meshing teeth of bevel gears, as well as improvement of the production technology-by using the tools of mathematical modelling [35][36][37][38] • Case studies, focusing on the explanation of operational causes of bevel gear scuffing, surface fatigue wear (pitting), and teeth breakage in various vehicles, machines, and devices, i.e. lorry transmission, turbojet gearboxes, or in the transmissions of industrial conveyors [39][40][41] In spite of the test rig, for the investigation of bevel gears, a necessary factor is the usage of proper test methods. Unfortunately, a review of the most common standards indicates that there is a complete lack of any standardised methods for testing scuffing of bevel gears.…”

In spite of long-term development of the technology of bevel gear production, the automotive industry reports various operational demands such as the need of the size and mass reduction of gears without lowering their durability and reduction of friction leading to a decrease in the energy losses and a decrease of the tendency to scuffing. What is more expected, EU regulations may impose the use of new generation gear oils (ecological-friendly) providing the proper operational properties of the transmission. In view of these demands, a new, bevel gear test rig and scuffing test method have been developed at ITeE-PIB. The idea resulted from a necessity to improve reliability of tests-popular gear tests are run mostly on spur gears having the tooth geometry significantly different than bevel gears. The test rig, test method, and results of verification testing are presented. The effect of various gear oils and the deposition of a low-friction coating on the resistance to scuffing were investigated. It is shown that the new test rig fulfils the research requirements and that the new test method has a good resolution.

gears are machine elements which used to transmit motion and power by the successful engagement of teeth. Two gears engaged with each other, the "gear" is having the larger number of teeth and the "pinion" is having the smaller number of teeth. It is said to be failed when any component is unable to perform one or more of its functions well before its expected service life. Bevel gears are widely used to transmit motion and power at shaft angle of 90° or else and it is widely used in gearbox. If it fails it is a major problem considering criticalness as it will fail to transmit motion and power and the whole assembly will fail to work.
