Internal leakage occurs in a lot of hydraulic components; pumps, hydromotors, spool sliding valves. Inside of them a gap exists between the two elements with relative velocities.

Characterization of the surface topography of materials is important in applications involving friction, lubrication, and wear. The essential feature is the hardness of materials.

The viscosity of a hydraulic fluid is one of its most important material properties. The choice of the appropriate viscosity of the fluid for a particular application is one of the most important tasks of a hydraulic engineer.

Simulations of human emotions under real conditions are very popular nowadays. A simulation of six degrees of freedom was made possible by the development of the Gough-Stewart platform in 1947. The electrically driven miniature Stewart platform…

Gears featuring the curved path of contact were implemented in heavy industry where it was proven that such gears can successfully replace involute gears. Purely graphical method of design was later replaced by an analytical definition…

The article presents the implementation of a control unit device for testing central drives for electric bicycles. The device is used for performing life time tests in development and early production stages. The core of the control system is the application developed in LabVIEW environment running…

Collaborative robots or cobots are becoming a common sight in industrial production. Even though some development still needs to be done they already efficiently support assembly process optimisation. To ease their inclusion in production, it makes sense to clarify their features and where their use is appropriate. Collaborative robots…

When welding stainless steel pipes, it is crucial to assure adequate welding conditions inside the pipe where the root is formed. The weld root characteristics need to be mechanically as well as physiochemically acceptable.

A design and development of a planocentric gearbox to be used in robot arm joints, namely for a collaborative robot, is presented in the papers. Besides strict limitations regarding the near zero backlash, the output position and torque should be available as well. So, a spatial-awareness encoder and a torque sensor are incorporated in a gearbox…
