New Range Of Reinforced Rubber Springs

An extensive range of reinforced rubber springs are now available from stock or on short lead time to suit a broad range of requirements

Primarily used in the mining/mineral processing sector as isolators for vibratory screens and similar equipment, their versatility and simplicity of installation makes them an alternative to some types of open spring mountings.

By virtue of the relatively high deflections achieved under loading, the natural frequency achieved by these mounts exceeds that achieved by solid rubber mounts. The low natural frequency provides high levels of vibration isolation in the typical frequency ranges in which these are used.

Vibratory screens, conveyors, sieves, concrete settling moulds.

For typical applications the rubber springs must be aligned vertically such that the principal loading is compressive. In all instances, the mounts must be supported on a flat surface and with a central locating element as illustrated below. If a larger flat surface is available then the locating element can be attached to this for simplicity of installation.

The materials used are high quality natural rubbers for the core material, a high strength bias cut tyre cord and an abrasion resistant rubber outer layer.

Minimum load for these products occurs requires a deformation of approximately 15% of the free height.

Maximum loading occurs at approximately 27.5% of the free height. Maximum stroke at maximum loading is approximately 10% of free height.

Bonding of rubber materials, particularly to metallic substrates is a primary skill within AVMR. The specialisation for providing isolation solutions utilising a wide range of materials and techniques remains a core strength of the business for its vibration and shock mitigation sector.
