An antivibration mounting comprises a base plate 1, with a top hat central section, and a top plate 4 onto which equipment is to be mounted. An inflatable toroid 10 is positioned between the top plate and the base plate. <IMAGE>

Description

SPECIFICATION Inflatable anti vibration mounting This invention related to anti-vibration mountings, and particularly, but not exclusively to anti-vibration mountings for heavy machinery such as a diesel engine where vibration is excessively high and requires to be damped. It can be scaled up or down to allow its use on either small or large applications.
According to the invention there is provided an anti-vibration mounting comprising a housing having a horizontal base member with an upstanding vertical wall distanced from the perimeter of the horizontal base. The top of the upstand has a horizontal surface with a hole in its center. A planner member spaced from the base member and above it has a verticle downstand. Between the two members is positioned a trodial member, within the center of the lower member is position a compression spring connected to the upper member by a rod. The lower end passing through the centre of the spring. The upper end being threaded passing through a hole in the upper member topped by an spring adjusting nut the toroidal is filled with either a gas or a liquid, or a combination of the two, also a sponge like material can be used. Mountings can be used either singly or in combination.The compression spring could be replaced by another toroidal member or soft rubber solid member.
The invention will now be described with reference to drawing Figure 1 and Figure 2. The base member .1. is attached by bolts or welding to the 14 structure from which vibration is to be isolated.
Within its hollow central upstand is housed 2.

The rod then passes through the center of 3. guide mounted in the center of 4. top planar member being distanced from the lower member. The rod then passes through 5. attachment foot or bracket of vibration generating equipment mounted on the unit. Above a washer is positioned an .6. adjusting nut on the upper threaded end of the rod. 7. lock nut is positioned above this .8. slot in the rod enables .6. adjustment nut to be adjusted by keeping the rod stationary .9. a rubber member is attached to the underside of the .4. top member. 10 .

The top of the upstand having a central horizonal surface with a hole at its centre of greater diameter than the central rod which passes through it. This section being in the form of a hollowtop hat section. The base member being attached to items from which vibration is to be isolated.
Distanced from the base member is a top plate comprising a planner member with a vertical down stand at its outer perimeter and a central hole with a guide mounted to and below the top plate around this central hole. A rubber member is positioned between the undersurface of the top plate and the top of the base member. Between the base member and the top plate is positioned a toroidal member which can be filled with either a gas, liquid or combination of the two via a filling or inflation attachment reinforced areas ofthetoroid resists damage caused by ingress of damaging materials.
Within the hollow top-hat section of the base member is housed a compression spring, spaced between the undersurface of the top hat section and the top of a flange or washer attached to the central threaded rod, which passes through the centre of the compression spring, up through the hole in the top of the top hat section of the base member, through the central hole in the top plate through the attachmenu foot or fitting of the equipment to be mounted on the unit and finally through the adjusting and lock nuts, securing the mounted equipment to the anti vibration mounting.
2. An anti-vibration mounting as claimed in claim 1 having the compression spring replaced by an inflatabletoroid.
3. An anti vibration mounting as claimed in claim 1 having the compression spring replaced by a solid block of suitable material and shape.
4. An anti-vibration mounting as claimed in Claim 1 having the compression spring replaced by a sponge or pourous member.
5. An anti-vibration mounting as claimed in Claims 1,2,3 and 4 the main toroid being replaced by a sponge or pourous member.
6. An anti-vibration mounting as claimed in claim 1,2,3 and 4 the main toroid being replaced by a solid flexible material.
7. An anti-vibration mounting as claimed in claim 1,2,3 and 4 the main toroid being replaced by a combination of gas, liquid and solid material.
