Eccentric shaft structure and its working principle, how to process eccentric shaft

Hello, I have seen your question and am sorting out the answer, please wait a while

Structure: The eccentric workpiece is the workpiece in which the outer circle and the outer circle of the part or the outer circle and the axis of the inner hole are parallel and do not coincide, and deviate by one distance. The distance between these two parallel axes is called eccentricity.

The part of the outer circle and the outer circle eccentricity is called an eccentric shaft or eccentric disk; The part where the outer circle and the inner hole are eccentric is called an eccentric sleeve.

Principle: Eccentric axisWhen a circle does not rotate around its center, it becomes an eccentric wheel. Eccentric shaft is also a kind of cam, generally speaking, the main purpose of eccentric wheel is to produce vibration, like electric sieve, the vibrator in the mobile phone is used eccentric wheel, most of the eccentric wheel is a round wheel, because the circular wheel is easy to manufacture and the process is simple.

English eccentric shaft and its name is the same, its center is not in the center of the axis, the general axis, can only drive the workpiece to rotate, but the eccentric shaft, not only can transmit the rotation, but also can transmit the role of the axis eccentric shaft: in order to facilitate the adjustment of the center distance between the shaft and the shaft, the eccentric shaft is usually used in the plane connecting rod mechanism V-belt transmission! Structural characteristics of eccentric shafts:

Two axes are parallel but do not coincide Definition: A workpiece whose outer circle is parallel to the axis of the outer circle but does not coincide is called an eccentric axis.

The three-jaw chuck can pad the pad block and give you a formula x= x pad thickness e eccentricity distance k correction value.

In fact, it is enough to make an eccentric wheel sleeve and lock it on the outside of the workpiece, and the eccentric wheel can be cut by wire.

To make an eccentric tooling, the workpiece is stuck on the tooling, and the tooling is then clamped on the chuck.

In order to facilitate the adjustment of the center distance between the shafts, the eccentric shaft is usually used in the V-belt drive of the plane linkage mechanism!

The structural characteristics of the eccentric axis: the two axes are parallel and do not coincide.

Definition: A workpiece whose outer circle is parallel to the axis of the outer circle but does not coincide is called an eccentric axis.

Applications of eccentric bearings: reducers, petrochemicals. Textile, metallurgy, mining. steel mills, etc. Light and heavy machinery, etc.

Eccentric bearings mainly include outer rings, inner rings, rolling element flower baskets, and rolling elements. The eccentric bearing structure is simple, easy to use, makes the eccentric mechanism greatly simplified, and makes the machining of the eccentric mechanism labor-saving, time-saving, and easy to assemble at the same time.

The eccentric bearing is a very important bearing in the cycloidal reducer. The original eccentric bearing consisted of three parts: an eccentric sleeve and two 502 series cylindrical roller sets. The eccentric sleeve and the inner ring of the bearing are integrated into one to form an eccentric bearing.
