Then the nanoscale friction can be expected to be reduced if the same system as the above is constructed at nanoscale. This is the initial concept of the present work of superlubricity. Here the combination of the graphene (nanosheet) and the fullerene C_(60) (nanoball) is adopted [Fig. ...
Dear all, I want to design a mechanism with two rotational part. The first one is rotating with constant speed. The second one is a disc with 8 bearings that each one goes through a groove inside the first part. What is the best and most accurate way to model the shape of groove so...

(M D Ellul); durability (A Stevenson and R Campion); design of components, including shear and compression bearings, and vibration and noise control (P M Sheridan, F O James and T S Miller); finite element analysis (R H Finney); and tests and specifications (J G Sommer and Oon Hock ...
Bearings operate through a combination of design features that enable them to reduce friction and facilitate smooth rotational movement. The inner and outer rings of a bearing are precision-engineered to provide a stable and accurate alignment. These rings are typically made of hardened steel or othe...
bearings. During the test, a pin that parallels the size of the intended shaft is inserted through the top of the press fit bearing. If it falls through the bearing by virtue of its own weight, it’s a “go”. If the pin sticks or fails to fall through the bearing, it’s a “...
Usually, wheel bearings are designed to last as long as the vehicle and don't require scheduled replacements or lubrication. They, however, wear out over time and will have to be replaced. This article points out the tell-tale signs of worn-out wheel bea
Wheel bearings are an essential component in the functioning of any vehicle. They bear the weight of the vehicle and facilitate smooth rotation of the wheels. However, choosing the right wheel bearings can be a daunting task for many vehicle owners out t
It is always a good idea to spread these bearings as far apart as your design will allow. Example: When designing a four-bearing, two-rail system, and the two bearings on the fixed rail are 10-inches apart, then both the drive force and applied mass-force need to be within 20-inches...
Devices that use helical gears have bearings that can support this thrust load. The bent teeth of helical gears means they have to be staggered, with the teeth of the next gear going in the opposite direction so the teeth can mesh. Each gear is called "right-handed" or "left-handed" ...
