A combination of two angular type ball bearings provided in a face-to-face arrangement to form a ball bearing unit in which the diameter of the balls of the second ball bearing is less than the diameter of the balls of the first ball bearing. This ball bearing unit is used at high spee...
(c) Shows the model of the full testing assembly for more precise calculations of uneven surfaces. Additionally, the influence of uneven surfaces of the loading ring and thus uneven load application was examined using FEA. For this investigation, a simplified 3D-model had to be used (no ...
Applying theoretical modeling (quantum calculations) the β-CD/CA interaction was confirmed and the binding sides were determined. During ball milling at room temperature citric acid was found to be located inside the β-CD cavity, accompanied by partial cyclodextrin dehydration. The results obtained ...
E design bearings accommodate very high speeds and relatively high loads. 719 E (VEB) 719 B (HB) A a° r1, r3 b° r2, r4 Optimized design of the bearing ring chamfers facilitates mounting. 70 E (VEX) 70 B (HX) High-speed E design bearings can accommodate higher speeds...
An anomaly detection model was developed for the purpose of analyzing the operational behavior of the two bearing units. A stacked sparse Long Short-Term Memory Autoencoder was successfully trained on the data obtained from the left unit under normal operating conditions, learning the underlying ...
A square base for the frame is chosen as this the most convenient. For the calculations we considered that 2 rows of balls are stored on top of each other which determines the height of the basket, namely 8 cm, and based on this the dimensions of the width and length are 26cm and 13...
Moreover, while compression itself has little bearing on the distance performance of a ball, compression can affect the playability of the ball on striking. The degree of compression of a ball against the club face and the softness of the cover strongly influences the resultant spin rate. Typic...
The sodium loss in the formation of the SEI is similar to what is observed in the case of Li-ion batteries (LIBs), which has been widely studied. Because the only source of Li in the Li-ion cell is the Li-bearing electrode, compensating for lithium loss in the formation of the SEI ...

Both calculations are based on the combination of Hertz contact theory and deformation compatibility the- ory. The only difference is that the direction of the inertial force acting on nuts A and B is switched. In this case, the equivalent axial stiffnesses of nuts A and B are calculated as...
