Vertical balancing machine with cartridge assembly

A vertical balancing machine comprising;

• a base carrying a horizontal support plate having an aperture,
• a suspension cartridge secured to the support plate for assembly and removal as a unit and at least in part depending through the aperture,
• the suspension cartridge having a pair of vertically spaced, rigidly interconnected suspension elements, each suspension element having an associated transducer for sensing unbalance signals, and a vertical spindle journaled in the suspension elements, and
• motor means supported on the base in driving relation to the spindle,
• wherein the suspension elements have central apertures for receiving a spindle cartridge, and the spindle cartridge comprises a tubular housing which snugly fits within the central apertures, a spindle shaft, and a pair of spaced bearing means for mounting the spindle shaft within the housing.

A vertical balancing machine comprising:

• a base carrying a horizontal support plate having an aperture,
• a suspension cartridge secured to the support plate for assembly and removal as a unit and at least in part depending through the aperture,
• the suspension cartridge having a pair of vertically spaced, rigidly interconnected suspension elements, each suspension element having an associated transducer for sensing unbalance signals, and a vertical spindle cartridge secured in the suspension elements for assembly and removal as a unit, and
• motor means supported on the base in driving relation to the spindle cartridge, wherein the vertically spaced suspension elements define a pair of vertically spaced axially aligned apertures, and wherein the spindle cartridge comprises a rigid tube snugly mounted in the axially aligned apertures of the suspension elements, a spindle, a pair of vertically spaced bearings for rotatably supporting the spindle in the tube, and means for coupling the spindle to the motor means.

A vertical balancing machine comprising;

• a suspension cartridge secured to the support plate for assembly and removal as a unit and at least in part depending through the aperture,
• the suspension cartridge having a pair of vertically spaced, rigidly interconnected suspension elements, each suspension element having an associated transducer for sensing unbalance signals, and a vertical spindle cartridge slidably secured in the suspension elements for assembly and removal as a unit, and
• motor means supported on the base in driving relation to the spindle cartridge,
• wherein each suspension element includes a plate with a central bore for receiving the spindle cartridge, a pair of arcuate slots through the plate and concentric with the bore for defining inner and outer plate portions and webs between the ends of the slots serving as flexure means, the webs of both suspension elements residing in a common diametrical plane of the bores.
