BALL AND BEARING NOMENCLATURE

High cutting speeds and feeds are essential requirements of a machine tool structure to accomplish its basic function which is to produce a work piece of the required geometric form with an acceptable surface finish at as high a rate of production as is economically possible. Since bearings in high speed spindle units are the main source of heat generation. Friction in bearings causes an increase of the temperature inside the bearing. If the heat produced cannot be adequately removed from the bearing, the temperature might exceed a certain limit, and as a result the bearing would fail. To analyse the heat flow in a bearing system, a typical ball bearing and its environment has been modelled and analysed using the finite element method. The maximum temperature in the bearing has been calculated as a function of heat generation with the rotational speed as a parameter. The goal of this analysis is to see how fast the temperature changes in the bearing system with respect to rotational speeds. In this thesis, at high speed range, a steady state thermal-stress simulation is performed by using FEA method to investigate temperature distribution of the bearing and the result shows that the temperature increases gradually with increase in rotational speed and it is validated by analytical formulation done. Further the increase of rotation speed the inner ring centrifugal displacement increases which causes larger contact deformation and stress. The dynamic stiffness of the variable preload bearing is analysed analytically and it is found that the radial stiffness decreases with increase in rotational speeds.

Improving Bearing Life and Performance with Computational Testing

Sentient Science

Bearing manufacturers and their customers are seeking solutions to speed time-to-market of new products, increase customer confidence during sales cycles, and generate new revenue streams. Physical testing capabilities and industry standards are important for the product design and validation process. However, some of the bottlenecks such as the cost and time can increase the risk of developing innovations, increase the time-to-market of new products, and cause customer to have low confidence of product performance at new product launch.

Removing metal fatigue for wind turnbine operators

Dermott Reilly

Rewitec is a nano coating that enables metal friction, wear and tear to be removed! This has remarkable positive values for anyone working with gears, engines, pistons or bearings as it enables metal stresses and wear to be better managed or removed altogether. Hence, engines, turbines have more power, with reduced fuel and oil consumption; worn out metal surfaces are repared; protection against new wear inbuilt; reduction of engine noise and diesel soot, all with lower omissions for your company and the environment. This is all good news.

A Strategic Approach: GenAI in Education

Peter Windle

Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction. This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation Blue Star - Saka Neela Tara

Balvir Singh

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup. The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Synthetic Fiber Construction in lab .pptx

Pavel ( NSTU)

Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
