Abstract
The invention discloses a kind of elastic supporting device free of tangential damping, including spring and spring base, spring base includes that spring mounting head and mounting head pedestal, spring mounting head and mounting head pedestal are hinged and connected, and spring is connected between spring mounting head and mounting head pedestal.It is arranged vertically within perpendicular for the resilient supporting unit one of two said structures horizontal 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 said structure being vertically arranged is positioned at the horizontal interval of upper connecting base and lower connecting base formation.Use the hinge arrangement formula design of spring base, the radial motion degree of freedom of open spring, simultaneously design " cross formula " spring structure, make resilient supporting unit make the even resilient motion at all-round angle, it is achieved optimal vibration effect sufficient, omnibearing, undamped.
Description
Technical field
The present invention relates to vibrating machine technical field, more specifically a kind of elastic supporting device free of tangential damping.
Background technology
The core technology of vibrating machine: allow vibrating machine effectively " vibrate " work done exactly.
Such as: vibrosieve be the capital equipment in crushing production line this, be typical vibrating mechanical equipment.It is off axle in the another parts one of the machinery that vibration is relevant, and two is spring.The vibrating effect of vibrating machine is also the most 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.
Vibrosieve is when crushing operation: 1, produced " exciting " power by eccentric shaft；2, support screening envelope by one group of spring assembly, make screening envelope be in suspended state, make screening envelope circle (or straight line or elliptic motion), to complete screening operation.
The resilient supporting unit structure (such as Fig. 1) of prior art, is to be directly connected in by spring 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, it is there is no freedom of motion (the radial direction degree of freedom produced by spring is atomic little).It is sufficient for i.e. only having the motion in vertical direction, and has damping in the horizontal direction and interrupted.This is the most unfavorable to mechanical vibration:
Theory and realization are all it was demonstrated that there is method linearly coupled to have again the screening effect of radial vibration, and the screening not having radial vibration than only method linearly coupled is superior, does not has the screening of radial vibration easily to make sieve screen apertures putty.
So, the radial direction damping characteristic (i.e. radially without freedom of motion) of the spring assembly structure of prior art, is to restraint the big obstacle that book vibrating machine effectively vibrates.
Summary of the invention
Present invention aim to overcome that more than prior art is not enough, it is provided that a kind of simple in construction, dependable performance, economical and practical " elastic supporting device free of tangential damping ".
In order to reach object above, the present invention is achieved by the following technical solutions: a kind of elastic supporting device free of tangential damping, including spring and spring base, it is characterized in that, described spring base includes spring mounting head and mounting head pedestal, spring mounting head and mounting head pedestal are hinged and connected, and spring is connected between spring mounting head and mounting head pedestal.
As preferably, it is arranged vertically within perpendicular for the resilient supporting unit one of two said structures horizontal 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 said structure being vertically arranged is positioned at the horizontal interval of upper connecting base and lower connecting base formation.
The present invention has two big notable architectural features: one be spring base head be hinge arrangement；Two is spring composition " cross formula " constructional device of resilient supporting unit.
Opening one's minds of the present invention is: use the hinge arrangement formula design of spring base, the radial motion degree of freedom of open spring, design " cross formula " spring structure simultaneously, makes resilient supporting unit make the even resilient motion at all-round angle, it is achieved optimal vibration effect sufficient, omnibearing, undamped.
The core technology of the present invention is: spring base " hinge arrangement contact " design is replaced prior art " direct contact type ", it is achieved the nothing radially damping vibration of spring.
The remarkable result of the present invention is: eliminate the radial direction damping of prior art spring assembly, makes vibration the most abundant on normal and radial direction both direction.
In addition to above notable function, the present invention also has following beneficial effect:
1. save V-belt；
2. exploitation screening function；
3. anti-resonance vibration；
" elastic supporting device free of tangential damping " designs, and eliminates " radially damping " drawback during vibrating machine runs, improves the work doing efficiency of vibrating machine, is the big technological progress of in vibrating machine technical field.

Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
Embodiment 1: as shown in Figure 1, a kind of elastic supporting device free of tangential damping, including spring 5 and spring base, spring base includes spring mounting head 3 and mounting head pedestal 4, spring mounting head 3 and mounting head pedestal 4 are hinged and connected, and spring 5 is connected between spring mounting head 3 and mounting head pedestal 4.
Embodiment 2: as shown in Figure 2, it is arranged vertically within perpendicular for the resilient supporting unit one of two said structures horizontal 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 of upper connecting base 1 and lower connecting base 2 formation, and the resilient supporting unit of the said structure being vertically arranged is positioned at the horizontal interval of upper connecting base 1 and lower connecting base 2 formation.
Embodiment 3: the structure in embodiments of the invention 2 is applied in reality, as it is shown on figure 3, pedestal 6 by mechanism positions of the present invention on stand 7, pedestal 6 is provided with main frame mounting seat 8 and motor mount 9.
The embodiment of the above is only the preferred embodiments of the invention, not limits the practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are made, all should contain within the scope of the present invention.
