ABSTRACT:
Disclosed subject matter includes flexible motor mounting members particularly adapted for vibration induced flexing movement combined with oscillatory movement about a pivot axis at a point of attachment on a blower housing or other support. Short but strong mounting members are provided that have low torsional mode vibration transmissibilities. Leaf spring mounting arms have low torsional spring constants and yet have sufficient strength to withstand shipping and handling loads for motor blower assemblies and to permit all angle motor mounting. 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. However, the characteristic torsional mode vibration transmissibility is substantially less than unity. In particularly preferred embodiments of the invention, sheet steel having a martensitic grain structure is utilized to form the mounting members. Bends in this material have a radius of at least seven times the thickness of the material. One method includes forming lugs or mounting members from the selected material and then trapping one end of these members between oppositely facing surfaces of fastening members. In some forms, the motor shell constitutes one fastening member and a holding plate is another fastening member, and it is preferred to capture a motor pad portion of the lug against the motor shell and projection weld the projections from the plate to the motor shell. The free end of the lug is specifically configured to prevent deformation and tearing, and the lugs are extremely easy to mount to a blower housing imply by deflecting the mounting arms (when necessary) with finger pressure so as to align holes in the mounting arms with previously provided holes in the blower housing. In another form, the motor end of mounting lugs are trapped between two pieces of steel that are welded together to form a mounting block having a strap accommodating slot therein.
