A spindle mounting for a wheel balancing machine of the kind in which the spindle is arranged substantially horizontal and has a cantilevered end portion for receiving a wheel to be balanced. The mounting includes a housing for rotatably supporting the spindle, and flexible support means connecting that housing to a base which is securable to a frame of the balancing machine. The support means includes at least three elongate support members which extend transverse to the spindle axis and are arranged in spaced side by side relationship, and an elongate restraining member arranged substantially parallel to the spindle. The support members are connected between the housing and base to provide column supports for the housing, and the restraining member has its opposite end portions connected to the housing and base respectively to hold the housing against endwise movement relative to the base. Each support member and the restraining member has sufficiently low lateral stiffness to permit relatively free lateral movement of the housing relative to the base in a plane extending transverse to the support members. A pair of force transducers are secured to the base and are connected to the housing through elongate reactor members so as to respond to lateral movement of the housing by generating a signal characteristic of the force causing that movement, and each reactor member is elongate and has sufficiently low lateral stiffness to substantially limit the transducer response to those forces acting in the aforementioned plane laterally of the spindle.

A balancing machine spindle mounting including: a housing; a spindle rotatably mounted on said housing and having a cantilevered end portion projecting beyond said housing to receive a workpiece to be balanced; a support base; flexible support means connecting said housing and base and including, at least three elongate support members which extend transverse to the axis of said spindle and are arranged in spaced side by side relationship, said support members being connected between said housing and base to provide column supports for said housing, and each said support member has sufficient low lateral stiffness to permit relatively free movement of said housing relative to said base in all directions within a plane extending transverse to said support members; and an elongate restraining member arranged substantially parallel to said spindle and having opposite end portions connected to said housing and base respectively so as to restrain said housing against endwise movement relative to said base in the axial direction of the spindle, and said restraining member having sufficiently low lateral stiffness to permit relatively free movement of said housing relative to said base in all other said directions within said plane.
