Abstract
An electric motor drive for rotatably driving a spindle of a spinning machines has a resilient member positioned between an interconnecting member and a sleeve mounted to the spindle bank of the spinning machine. The resilient member is partially received in a recess in the interconnecting member, the sleeve or both to facilitate the distribution of forces exerted on the resilient member.
Claims5
In a textile machine of the type having a spindle bank, an apparatus for rotating a bobbin during the building of textile material thereon, comprising:
- a spindle having an axis for supporting a bobbin thereon during rotation of said spindle;
- a rotor fixedly mounted to said spindle;
- a stator for driving rotation of said rotor, said stator having a base;
- means, fixedly connected to said stator, for supporting said rotor at a predetermined axial spacing above said stator base, said rotor supporting means rotatably supporting said rotor during driving rotation of said rotor and said rotor supporting means being connected to said stator for transmission of vibratory forces associated with driving rotation of said rotor from said rotor to said stator;
- and
- means for damping the transmission of vibratory forces from said stator to the spindle bank, said damping means including a resilient member disposed between and in contact with said stator base and the spindle bank, whereby said stator and said resilient member act to stabilize said spindle during a yarn package building operation by damping the vibratory forces generated by the rotation of said rotor.
