Straight-line oscillation machine
Technical field
The present invention relates to a kind of vibrative machine, especially a kind of machine that produces straight-line oscillation.
Background technology
Straight-line oscillation machine is the plant equipment that produces straight-line oscillation, and its application is very extensive, as: can be applied in vibratory sieve the coarse and fine separation for product; Also can be for powder jolt ramming in mould, form product, in addition also can also be for detection of the deburring of product vibration-resistant property and metal and the nonmetal various parts of making, derust, rounding and brilliant polish operation.
In prior art, bobbing machine mainly contains two kinds:
Be a curve bobbing machine, it drives a pair of eccentric wheel to rotate by motor, produces centrifugal force, forming curves vibration.The shortcoming that this traditional curve bobbing machine exists is: the direction of (1) its vibration cannot keep rectilinear direction accurately, and the direction of the centrifugal force that produces of eccentric wheel is not positioned at same rectilinear direction completely according to the principle of Mechanics Vector stack, cause unnecessary energy dissipation; (2) vibration force depends critically upon eccentric size, for some, need the equipment of larger vibration power, need to be by eccentric size design very large, not only cause equipment volume huge, but also make the driving force of motor require high, improved the cost of equipment.
