A device for the compensation of bearing forces for machines with a shaft that is acted upon by an axially working force, is described. At one shaft end is provided a counter-pressure bearing for the subjugation of the shaft to an axially working counter-force whose size corresponds preferably...

Therefore, the main bearings in the model are represented by the resultant of the above forces (for the front and rear main bearings) and shown in Fig. 31.2. When the combustion force is at its maximum the bearing reaction forces also reach their maximum values. Sign in to download full-...
Bearings are the most frequently used machine element in power transmission. A poorly designed rolling bearing can quickly lead to damage of the bearing itself and the drive train. In the worst case, a chain reaction induces the total loss of your complete system. Detailed basic research works ...
A specially designed and constructed test setup is used in this work to conduct running tests on rolling bearings lubricated with the novel grease, as shown in Fig. 1. The test rig consists of an induction motor, a flexible coupling, a base, a rotating shaft, two supporting bearings, and ...
The bearing reaction moment on the shaft is very sensitive to misalignment in the bearing. Plots of the bearing moment for aligned and misaligned bearings are shown below. Moment on the shaft for an aligned (left) and misaligned (right) bearing. ...
the unit shaft resistance in the same soil increases. It is because rock has a larger standard value of unit skin resistance compared with soil, and the interaction between the pile and the rock requires greater forces to produce the same displacement compared to the interaction between piles and...
make an important contribution to this. Rolling bearings in gearboxes support the shaft and facilitate the transmission of forces. This means that they must with-stand extreme loads in complex environmental conditions. The most frequently used bearing types are tapered roller bearings, four-point cont...
In the absence of high shaft inclination the magnitude of the bearing forces depend on the characteristics of the wake field, the geometric form of the propeller (in particular the skew and blade number), the ship speed, rate of ship turning and the rotational speed of the propeller. Indeed...
