Abstract
This is a kind of deviating heart piece largely use on the vibrating machine while moving. The deviating heart piece is circle, inside there is some cavity, or filled with the things of different weight with the piece. While working, the deviating heart piece turns to move around the center of the circle.
Description
Affiliated technical field
Invention relates to a kind of eccentric block that generally adopts on vibrating machine, especially be installed in the vibrating bin, produces the eccentric block of exciting force during revolution.
Background technology
At present, it is semicircle or fan-shaped mostly known eccentric block is, also has gyroaxis to depart from the circular eccentric block in the center of circle.The gyroaxis of eccentric block departs from the center of gravity of eccentric block, has eccentric moment, just produces circular centrifugal power during revolution, i.e. exciting force makes vibrating machine work.The deficiency of existing eccentric block is, bounce during the eccentric block revolution with the agitated vibrations case in lubricating oil, cause steering resistance big, problems such as lubricating oil heating, especially at vibration at high speed mechanically, problem is particularly outstanding.
Summary of the invention
For overcoming the deficiency of existing eccentric block, the invention provides a kind of eccentric block, this eccentric block can not bounce with the agitated vibrations case in lubricating oil.
The technical scheme that the present invention deals with problems is: eccentric block is for circular, and gyroaxis is coaxial with the center of circle.Resistance when this makes the eccentric block revolution is quite little.Meanwhile, part, the inside of eccentric block is a cavity, perhaps fills the object different with eccentric block proportion in the cavity, and this makes the center of gravity and the center of circle disalignment of eccentric block, and eccentric block has eccentric moment with respect to the center of circle.So, when eccentric block when the center of circle is turned round, produce exciting force too.
The invention has the beneficial effects as follows: circular eccentric block when the center of circle is turned round, can not bounce with the agitated vibrations case in lubricating oil, simultaneously, produce exciting force too.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of first embodiment of the invention.
Fig. 2 is the structural representation of second embodiment of the invention.
Fig. 3 is the structural representation of third embodiment of the invention.
Fig. 4 is the structural representation of four embodiment of the invention.
Fig. 5 is the structural representation of fifth embodiment of the invention.
Among the figure, 1. eccentric block, 2. little than eccentric block proportion light object is 3. than the heavy weight body of eccentric block.
The specific embodiment:
In first embodiment shown in Figure 1, an internal cavities is arranged at eccentric block (1) bottom, makes the center of gravity and the center of circle disalignment of eccentric block, and eccentric block has eccentric moment with respect to the center of circle.
In second embodiment shown in Figure 2, the little light object (2) of packing ratio eccentric block proportion in the internal cavities of eccentric block (1) bottom is as foamed plastics.Effect is with first embodiment.
In the 3rd embodiment shown in Figure 3, to have filled than the heavy weight body of eccentric block (3) in the internal cavities of eccentric block (1) bottom, this also makes the total centre of gravity and the center of circle disalignment of eccentric block, eccentric block has eccentric moment with respect to the center of circle.
In the 4th embodiment shown in Figure 4, eccentric block (1) has two internal cavities, filled in one of them cavity than the heavy weight body of eccentric block (3), another cavity is not filled object, this also makes the total centre of gravity and the center of circle disalignment of eccentric block, and eccentric block has eccentric moment with respect to the center of circle.
In the 5th embodiment shown in Figure 5, eccentric block (1) has two internal cavities, has filled in one of them cavity than the heavy weight body of eccentric block (3), and the light object (2) that another cavity packing ratio eccentric block proportion is little is as foamed plastics.Effect is with the 4th embodiment.
Claims (4)
1, a kind of eccentric block, its gyroaxis and center of gravity disalignment is characterized in that: the inside of eccentric block is local to be cavity, and profile is circular, and its gyroaxis is coaxial with the center of circle.
2, eccentric block according to claim 1 is characterized in that: filled the object different with eccentric block proportion in the cavity of the inside of eccentric block.
3, eccentric block according to claim 1 is characterized in that: there are a plurality of cavitys the inside of eccentric block, and the heavy object of packing ratio eccentric block in one of them or the several cavity is not filled object in all the other cavitys.
4, eccentric block according to claim 1 is characterized in that: there are a plurality of cavitys the inside of eccentric block, the little object of packing ratio eccentric block proportion in the heavy object of packing ratio eccentric block in one of them or the several cavity, all the other cavitys.
