Eccentric Turning Operation on Lathe Machine
Eccentric shaft and eccentric sleeve are generally processed on lathe machines. The machining principles of the two parts are basically the same, mainly differs in clamping methods. When machining eccentric parts on the lathe, the center of the eccentric part to be machined must be corrected to coincide with the center of the lathe spindle.

Centering eccentric shaft
Turn the 2" section then change to the eccentric holes and turn the shaft. Depending on the shock load you might get away with a 1 1/4 shaft with chunk of 2" set eccentrically in the middle. You could Locktite it for the initial hold then cross drill and taper pin or plug weld the cross pins.

Eccentric Bearings
Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants. Bearings with an eccentric-lock shaft mount are better than bearings with a set-screw shaft mount for high-speed applications, but only rotate in a single direction. For technical drawings and 3-D models, click on a part number.

What is an eccentric press used for?
How does an eccentric press work? Eccentric presses work when a flywheel is driven by an electric motor through a belt drive. At this moment, the movement is transmitted through a small and a large gear wheel, which will be mounted on the eccentric shaft. In short, these presses use a connecting rod that is implemented by means of a crankshaft.

Failure analysis of eccentric bushings in large gyratory crusher
The part where this failure occurred is the eccentric bushing. As the mantle shaft comes into direct contact with the eccentric bushing, a large ring of deposited layer can be observed in the middle-upper part of the lower shaft, as shown in Fig. 2 (a). This phenomenon indicates that strong oxidation has occurred at that location.

Eccentric shaft
The eccentric shaft is an essential part of the fully variable valve lift control. The valve lift changes continuously from maximum to almost zero by rotating / pivoting the eccentric (shaft) by means of an electric motor. This is a SELZER product, as a one-piece forged blank was replaced by individual parts (shaft, eccentric, control-sleeve gear).

E86 (N52K) Eccentric Shaft Sensor
Finally got round to replacing the eccentric shaft sensor on my E86. For some background, the N52 uses variable valve lift and timing to negate the need for a throttle body. It is fairly common for these sensors to go eventually, but curiously when they do they don't throw a CEL. Symptoms for me were: 1. Poor fuel economy (down about 15-20%) 2.

Eccentric Shaft
The oscillating member is supported on an eccentric shaft that rotates at half of the crankshaft speed in the same direction and is driven by the crankshaft. The oscillating member, eccentric shaft and crankshaft jointly impact the piston movement and give rise to a shorter intake and compression stroke than a long expansion and exhaust stroke.

In this paper a variant of eccentric drives will be described, which uses rolling elements instead of an eccentric gear. These rolling elements are constrained by a concentric carrier allowing for radial movement and are moved by an eccentric crank. They mesh with a gear geometry that translates their radial movement into tangential movement and constrains …

What Are The Uses Of Eccentric Bearings?
3. Realize the tilt of the rotation axis: By setting the eccentricity of different eccentric bearings differently, the tilt of the rotation axis relative to the main axis can be achieved. This is used when a certain inclination angle between the rotating shaft and the main shaft needs to be achieved in some special equipment such as centrifuges. 4.
