Today, gearboxes are inevitable in numerous applications requiring high power density including wind turbines, electric vehicles, cranes, robotics, etc. A combination of high-ratio gearboxes with high-speed, low-torque motors is often used to achieve high power density. Planetary gear trains (PGTs) help achieve a high gear ratio in a compact arrangement. Several configurations of planetary gears are widely studied in this article where the gear profiles used in these studies are primarily involute.
PT products such as gears, motors, pumps, fans and bearings will—without a doubt—continue to run through rigorous and harsh environments for the foreseeable future, but software and hardware improvements aim to disrupt unplanned downtime and machine maintenance through a series of new condition monitoring assets.
The Science Based Targets initiative (SBTi) has validated the Schaeffler Group’s targets for reducing greenhouse gas emissions as being in conformity with SBTi criteria and recommendations and hence in line with what the latest climate science considers necessary in order to meet the goals of the Paris Agreement. The global automotive and industrial supplier is committed to cutting its absolute Scope 1 and Scope 2 greenhouse gas emissions by 90 percent by 2030, with 2019 as its base year. The company has also set itself the target of reducing its absolute Scope 3 greenhouse gas emissions from purchased goods and services, fuel- and energy-related activities, and upstream transportation and distribution by 25 percent over the same period.
As of January 2023, Arkos Field Services, acquired by Burckhardt Compression in 2019, is integrated with Burckhardt Compression (US) Inc. Customers benefit from combined knowledge, expertise and unrivalled solutions for reciprocating compressors and other equipment from one provider. The integration of the two brands streamlines business processes to provide easy access and a solutions-driven customer experience.
The H2Eco Award is presented to national and international companies that contribute an outstanding commitment to a green hydrogen economy by technical innovation, economics and entrepreneurship according to the principles of economic efficiency, sustainability and security of supply. The contribution to protecting the climate stands in the foreground. The principle of H2Eco is an ecological and sustainable hydrogen future.
Clark Seals, a sealing technology company, recently announced that Jeff Thompson has joined the company as territory sales manager. In his new position, Thompson will manage sales operations in Texas, Oklahoma, Arkansas, Louisiana, Mississippi and Alabama.
On Wednesday, November 16 and Thursday, November 17, the Reggio Emilia’s plant of Kohler Engines sponsored and hosted the event "Alternative Fuels. A sustainable path to engines decarbonization", a workshop organized by SAE-NA, STEMS-CNR and Kohler.
Wind-turbine drivetrains undergo severe transient loading during start-ups, shut-downs, emergency stops, and during grid connections. Load cases that result in torque reversals may be particularly damaging to bearings, as rollers may be skidding during the sudden relocation of the loaded zone. Seals and lubrication systems must work reliably over a wide temperature variation to prevent the ingress of dirt and moisture and perform effectively at all rotational speeds in the gearbox. Many wind-turbine gearboxes have also suffered from fundamental design issues such as ineffective interference fits that result in unintended motion and wear, ineffectiveness of internal lubrication paths and problems with sealing. Improving the resistance of future gearbox designs to all these issues is a key to the future cost of energy generated by wind turbines.
Danfoss Power Solutions has appointed Ines E. Sira as the new president of its Fluid Conveyance division, effective immediately. Based at the company’s campus in Eden Prairie, Minnesota, Sira will be a key member of the Power Solutions leadership team and will report directly to Eric Alström, president of Danfoss Power Solutions.
