I would like to briefly discuss some thoughts on ball bearing efficiency specifically in terms of applied load and resulting stress. I don’t want to trivialize this subject; there are textbooks written on the subjects of electrohydrodynamic lubrication (EHL), octahedral subsurface shear stress and friction losses due to elastic hysteresis. This is a just a high-level discussion on the importance of individual bearing stress on efficiency.
Verification of a drive system should include all main elements of the system, which are gears, bearings, shafts, and depending on the application other parts such as screws, couplings, and connections. Gears are clearly the most complicated parts for verification, but in many cases, a gearbox failure has its origin in a shaft or bearing failure. The subject of this paper is to explain how verification of a drive system based on measured or simulated torque-speed-time data can be handled.
Siemens Digital Industries Software has announced the latest updates to its NX software from the Siemens Xcelerator portfolio bringing new and enhanced capabilities to Siemens’ flagship product engineering software that aim to help designers and manufacturers across all industries deliver better, optimized products to market faster.
It's no secret that cycloidal gearboxes are important in mechanical engineering, especially when it comes to precision motion control and efficient power transmission. The gear systems differ from harmonic wave/strain wave gearboxes by using a cycloidal disk and needle bearings to transmit torque with minimum backlash, achieve high reduction ratios, and support substantial loads. This Sumitomo Drive Technologies blog will talk about single-stage and multi-stage cycloidal gearboxes.
The new KISSsoft release 2024 is coming soon! This April will bring you the new system module KISSdesign, accelerating the calculation of complex drive trains and replacing the previous KISSsys software.
IIjin Electric's collaboration with Siemens began with the company's efforts to effectively integrate electrical design with mechanical design. “This collaboration went beyond simply changing tools. It represented a major advancement in the company's design approach and methodology.
With the release of version 9, the FVA-Workbench once again sets new standards in gearbox design, enabling the seamless integration of the latest research results into industrial practice. As a groundbreaking interface between collective research and application, the FVA-Workbench accelerates development and innovation in drive technology. This new release is more powerful than ever, with innovative features for flexible load spectra and improvements in FEM components and shaft-hub connections.
Portescap introduces the 08ECP20 brushless DC slotless motor, a mini actuation solution ideal for engineers looking to downsize devices and applications without compromising on performance or reliability. The 08ECP20 is the smallest frame size to join Portescap’s Ultra EC portfolio.
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.
