Abstract
Motor vibration isolating arrangements and systems using such arrangements are disclosed. In preferred arrangements, leaf spring mounting arms have low torsional spring constants and yet strength to withstand shipping and handling loads. The mounting member spring constants for axial, radial and tilting vibration modes are selected in specific forms so that the characteristic vibration transmissibility ratios for these modes are each close to unity, but so that torsional mode vibration transmissibility is substantially less than unity. In particularly preferred arrangements, sheet steel having a martensitic grain structure is utilized. In some forms, the motor shell constitutes one weldable member and a holding plate is weldable. The spring material is protected by heat sinking from being softening and weakened by conventional welding processes. The heat sinking members also contribute to a very strong fastening scheme.
