Profile grinding is the hard-finishing process of choice for large gears with demanding requirements regarding load transmission, running smoothness, and complex tooth modifications. No other hard-finishing process offers a comparable level of flexibility across such a wide range of applications. Profile grinding can be applied to very small as well as very large gears, to external and internal gearing, to involute and non-involute tooth forms, to components with and without interfering contours, and to both simple and highly complex tooth modifications. Furthermore, profile grinding allows the achievement of excellent quality levels that cannot be attained by any other hard-finishing process over this broad application range.
2023 is shaping up to be our planet’s hottest year on record, and the wind energy industry is feeling the heat. The GWEC (Global Wind Energy Council) says that the rate of wind turbine installations will need to quadruple globally by the end of the decade if we’re to achieve the IRENA’s (International Renewable Energy Agency) goal of net zero carbon emissions by 2050—and keep the average annual temperature worldwide from increasing more than the predicted 1.5° C. Fortunately, “net zero” commitments are gathering global momentum. Before year’s end, total global windpower is expected to reach a historic milestone of 1 TW of installed capacity, eliminating 1.2 billion tons of CO2 annually, roughly the equivalent of all the carbon emissions of South America.
In conventional gear manufacturing, quality control is carried out for a number of pieces per batch. Most parts enter final gearbox assembly without any inspection. Among other things, this approach is based on two facts: measuring time is significantly longer than the machining time, and the limited measuring capacity available.
