Abstract
The invention discloses an elastic supporting device free of tangential damping. The elastic supporting device comprises a spring and a spring seat. The spring seat comprises a spring installation head and an installation head base, wherein the spring installation head is hinged to and connected with the installation head base. The spring is connected between the spring installation head and the installation head base. The two elastic supporting devices of the structure are perpendicularly arranged on an L-shaped upper connecting base and an L-shaped lower connecting base in the transverse direction and the vertical direction respectively, the transverse elastic supporting device of the structure is located in a vertical interval formed by the upper connecting base and the lower connecting base, and the vertical elastic supporting device of the structure is located in a transverse interval formed by the upper connecting base and the lower connecting base. The hinge structure type design of the spring base is applied, and the radial moving freedom degree of the spring is increased; meanwhile, the cross-shaped spring structure is designed, and therefore the elastic supporting device does uniform elastic movement at full round angles, and the full, all-directional and damping-free best vibration effect is achieved.
Description
Technical field
The present invention relates to vibrating machine technical field, more specifically say a kind of resilient supporting unit without tangential damping.
Background technology
The core technology of vibrating machine: be exactly to allow vibrating machine " vibration " work done effectively.
For example: vibratory sieve be capital equipment in crushing production line this, be typical vibrating mechanical equipment.It is eccentric shaft in the relevant another parts one of machinery of vibration, the 2nd, and spring.The vibrating effect of vibrating machine is also just directly relevant to eccentric shaft and spring.The quality of eccentric shaft and eccentricity determine exciting force, and the elastic characteristic of spring determines vibration characteristics.
Vibratory sieve is when crushing operation: 1, by eccentric shaft, produce " exciting " power; 2, by one group of spring assembly, supporting screening envelope, making to sieve envelope in suspended state, making to sieve envelope and circle (or straight line or elliptic motion), to complete screening operation.
The resilient supporting unit structure (as Fig. 1) of prior art, is that spring is directly connected between screening envelope and base, and such result is: 1,, in spring normal direction, have freedom of motion; 2, at spring in the radial direction, be (the radially free degree producing by spring is atomic little) that there is no freedom of motion.Only having motion in vertical direction is fully, and has in the horizontal direction damping and interrupted.This is very unfavorable to mechanical oscillation:
Theoretical and realization all proves have normal vibration to have again the screening effect of radial vibration, than only having normal vibration, does not have the screening of radial vibration superior, does not have the screening of radial vibration easily to make sieve screen apertures putty.
So the radially damping characteristic (radially without freedom of motion) of the spring assembly structure of prior art, is an effectively large obstacle of vibration of bundle book vibrating machine.
Summary of the invention
It is above not enough that the object of the invention is to overcome prior art, and a kind of simple in structure, dependable performance, economical and practical " without the resilient supporting unit of tangential damping " are provided.
In order to reach above object, the present invention is achieved by the following technical solutions: a kind of resilient supporting unit without tangential damping, comprise spring and spring base, it is characterized in that, described spring base comprises spring fitting head and mounting head pedestal, spring fitting head and mounting head pedestal are hinged and connected, and spring is connected between spring fitting head and mounting head pedestal.
As preferably, by the resilient supporting unit of two said structures one horizontal one perpendicular being arranged vertically between two L-shaped upper connecting bases and lower connecting base, the resilient supporting unit of the said structure of lateral arrangement is positioned at the vertical interval of upper connecting base and lower connecting base formation, and the resilient supporting unit of the vertical said structure of arranging is positioned between the transverse region of upper connecting base and lower connecting base formation.
The present invention has two large significantly architectural features: the one, and spring base head is hinge arrangement; The 2nd, spring composition " cross formula " constructional device of resilient supporting unit.
Of the present invention opening one's minds is: the hinge arrangement formula design of using spring base, the radial motion free degree of open spring, design " cross formula " spring structure simultaneously, make resilient supporting unit make the even elastic movement at all-round angle, realize sufficient, omnibearing, undamped optimal vibration effect.
Core technology of the present invention is: to spring base with " hinge arrangement contact " design replace prior art " direct contact type ", realize spring without radially damping vibration.
Remarkable result of the present invention is: eliminated the radially damping of prior art spring assembly, made vibration at normal and radially all abundant on both direction.
Except above significantly function, the present invention also has following beneficial effect:
1. save V-belt;
2. exploitation screening function;
3. anti-resonance vibration;
" without the resilient supporting unit of tangential damping " design, has eliminated vibrating machine " radially damping " in service drawback, has improved the work doing efficiency of vibrating machine, is the large technological progress of one in vibrating machine technical field.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Embodiment 1: as shown in Figure 1, without a resilient supporting unit for tangential damping, comprise spring 5 and spring base, spring base comprises spring fitting head 3 and mounting head pedestal 4, spring fitting head 3 and mounting head pedestal 4 are hinged and connected, and spring 5 is connected between spring fitting head 3 and mounting head pedestal 4.
Embodiment 2: as shown in Figure 2, by the resilient supporting unit of two said structures one horizontal one perpendicular being arranged vertically between two L-shaped upper connecting bases 1 and lower connecting base 2, the resilient supporting unit of the said structure of lateral arrangement is positioned at the vertical interval that upper connecting base 1 and lower connecting base 2 form, and the resilient supporting unit of the vertical said structure of arranging is positioned between the transverse region that upper connecting base 1 and lower connecting base 2 form.
Embodiment 3: in reality, as shown in Figure 4, pedestal 6 is placed on stand 7 by mechanism of the present invention, is provided with main frame mount pad 8 and motor mount 9 on pedestal 6 by the structure applications in embodiments of the invention 2.
