China is leading the world in the construction of solar, wind and thermal power plants to support its increasing demand for electrical energy. For those that use steam turbines, boiler feed pumps (BFPs) are a crucial asset and selecting the best design to suit the needs of an individual station can have many benefits. When a recent project needed some of the largest start-up BFPs available, Sulzer was selected as the preferred supplier.
A calculation platform suitable for all areas of gearbox development
December 1, 2023
Developing a new gearbox series is costly and time-consuming. This is especially true in marine propulsion, as classification society certifications must be achieved in addition to the required verifications. For this reason, Reintjes offers the same drives for various types of ships. In gearbox development, this means that each application requires different loads and usage profiles, with different service lives and maintenance intervals. Thus, each drive must be designed and calculated with advance consideration of every possible profile.
The 2023 SPS trade fair in Nuremberg represented an important opportunity for Bonfiglioli to showcase its experience and expertise for industrial automation. This included mechatronic solutions specifically designed for packaging, intralogistics, robotics and IoT applications.
From 2022 to 2023, the global geared motors and industrial gears market is expected to experience a significant slowdown in growth. Interact Analysis' preliminary research shows that global sales of geared motors and industrial gears in 2023 are expected to be around $12.7 billion, a slight decrease compared with 2022.
Sumitomo Drive Technologies is expanding its range of precision gear products and upgrading its ECY series with higher torque and a plug & play drive for motor connection. The ECY series comprises high-precision shaft gears, used for example for surface machining in dental technology or in collaborative robots (cobots). Thanks to their internal cylindrical roller bearings, the gear units provide both high rigidity and higher performance in a smaller design envelope.
This report derives the equation for relative elastohydrodynamic lubrication (EHL) film thickness. Mineral (MIN), polyalphaolefin (PAO), and polyalkylene glycol (PAG) lubricants with viscosity grades of ISO 320, 150, and 32 are analyzed.
More energy efficiency, higher performance and better controllability are the main reasons why more electric drive systems are being operated with frequency converters. However, these devices can cause high-frequency, asymmetrical interference currents, which, as a current passage through the output and fan-side bearings, can cause damage and premature failure.
Current-compensated CoolBlue toroidal cores made of Magnetec’s nanocrystalline material Nanoperm have proven to be effective protection against such conducted interference and its consequences. In addition, the Nanoperm Line Absorbers NaLA can also be used to significantly suppress symmetrical interference currents.
From manufacturing to maritime, the quest for sustainable solutions has given rise to the development of environmentally friendly lubricants. Among these, Environmentally Considerate Lubricants (ECL) and Environmentally Acceptable Lubricants (EALs) have gained prominence for their positive impact on both equipment performance and the planet. Let’s delve into the differences and advantages of these lubricant classifications.
Portescap introduces the new R22T gearhead, the latest addition to its existing 22 mm gearbox portfolio. As a mid-torque gearhead, the R22T fills the gap between our light-torque R22 and high-torque R22HT gearheads. It is also fully compatible with Portescap’s brush DC and brushless DC slotless motors.
Rolling bearing calculations are usually based on the assumption of ideal nominal geometries. However, actual components and assemblies are always subject to statically distributed geometric deviations resulting from the manufacturing and assembly processes. This leads to changes in the internal geometric conditions which have an effect on bearing characteristics such as the service life. The FVA-Workbench makes it possible for users to consider these geometric deviations in bearing calculations for more reliable results.
