Abstract

The adaptive eccentric moment regulating system may be used in vibrating machinery, especially vibrating machinery with adjustable eccentric moment. By means of outside regulation of matched driving force source, the shaft and the adjustable gear may be turned by certain angle to change the angle between two sets of eccentric blocks and regulate eccentric moment.

Description

Self adaptation is regulated the system of eccentric moment

Self adaptation is regulated the system of eccentric moment.Invention can be applicable to oscillating machinery, the especially oscillating machinery of adjustable eccentric moment (as the vibration pile pulling sinker).

Background technology:

At present, the oscillating machinery of known adjustable eccentric moment (as the vibration pile pulling sinker) is all regulated angle between the eccentric block by regulating angle station, reaches the purpose of regulating eccentric moment.The existing angle station of regulating adopts planetary gears or spiral free-sliding spline mechanism, and regulates corner and rely on the inside of device own to finish, and makes complex structure, processing difficulties.

For overcoming the deficiency of prior art constructions complexity and processing difficulties, the invention provides a kind of self adaptation and regulate the system of eccentricity, this system is by adjusting the coupling of power source from the outside, just can make that gear turns an angle with respect to axle, reach the purpose of regulating corner, and then, regulate the angle between the eccentric block, finish the work of regulating total eccentric moment.

Self adaptation is regulated the corner system and mainly is made up of the gear that can relatively rotate certain angle and axle and two external power supplys.Under the influence of two external power supplys coupling, gear and the axle gear that two (group) eccentric block connects firmly that links respectively relatively rotates angle, changes the angle between the eccentric block, reaches the purpose of adjusting eccentric moment.This is easy to implement the method, and each one is simple in structure.

Below in conjunction with accompanying drawing and implementing method invention is further specified.

Fig. 1 is that self adaptation is regulated the corner system construction drawing.

Fig. 2 is the A-A sectional drawing of Fig. 1.

Fig. 3 is that the C of Fig. 2 is to view.

Fig. 4 is the B-B sectional drawing of Fig. 1.

Among the figure, 1. gear A, 2. eccentric block, 3. gear B, 4. spacer pin, 5. fixed cover, 6. gear C is 7. gone up power source, 8. descends power source.

Annotate: go up power source (7), power source (8) can be motor or the driving members such as belt wheel that driven by motor down.

The specific embodiment:

Among Fig. 1, last power source (7), following power source (8), driven wheel A (1), and then drive is fixed on the eccentric block of arranging up and down on each (2).

Among Fig. 2, gear B (3) and gear C (6) engagement.Fixed cover (5) is fixed on the axle, and gear B (3) is but relative fixed cover (5) turns an angle (general 180 degree).Spacer pin (4) is fixed on the gear B (3), rotates in the scope that makes gear B (3) to allow at two protuberances of fixed cover (5).

Implement to regulate corner, only need to regulate the coupling that goes up between power source (7) and the following power source (8).If last power source (7) is regulated the back than power source (8) is powerful down, fixed cover (5) driven gear B (3) then, both relatively rotate to an extreme position, and spacer pin (4) contacts with a protuberance of fixed cover (5) at this moment; And if power source (8) is more powerful than last power source (7) after regulating down, then gear B (3) drives fixed cover (5), both oppositely relatively rotate to another extreme position (generally differing 180 degree), and spacer pin this moment (4) contacts with another protuberance of fixed cover (5).At gear B (3) and fixed cover (5) simultaneously in relative rotation, driven the eccentric block of last row on each with respect to the change of arranging the angle of the eccentric block on each down.That is: under the influence of two external power supply couplings, reached the purpose of regulating eccentric moment.
