Prerequisites
The assembly to be mounted is not rigidly bolted to the base but is positioned on mounts that form a cushioned base. The assembly must have sufficient flexural and torsional strength so as to be able to absorb the internal forces without deforming. Otherwise the assembly's internal stiffness must be attained by means of a rigid foundation to which it is permanently attached or by means of an appropriate frame.
The outward convexity of the SCHWINGMETALL mounts on the side may not be impaired by structural alterations or additions.
Attachment
SCHWINGMETALL mounts can be bolted to the floor or to the machine on which they are positioned. If the machine mass is sufficiently great and the excitation forces sufficiently low, it is sufficient to attach the SCHWINGMETALL mounts to the machine. Shim matting and Compression/Shear mounts are ideal for this purpose.
Shims can be used to compensate for floor irregularities. Attachment bolts may not be allowed to penetrate the rubber-metal mount under any circumstances as this would destroy the mount's isolating effect.
Connections and belt pull
Care is to be taken to prevent rigid metal connections from destroying the isolating effect of the spring elements. Piping, shaft connections and the like must be equipped with sufficiently ductile separators and transition pieces.
External forces not absorbed by mounts - e.g. belt pull - must be intercepted by additional stopper devices. All spring connections including belt pull and the stopping devices used as buffers have an influence on the tuning of the mounts and must be taken into account in the vibration calculations.
Buffers and railstrips exposed only to static shear force should also be loaded in the pressure direction to compensate for the tension components generated.
Storage and cleaning
DIN 7716 contains general rules for the storage, cleaning and servicing of rubber and plastic products.
If necessary SCHWINGMETALL mounts can be cleaned with a glycerin spirits mixture (1:10). Solvents like benzene or benzole must not be used. Sharp-edged tools are likewise unsuitable for cleaning the mounts.
