Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
187 words
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.
Claim 2
Dependent Claim
187 words
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.
Claim 3
Dependent Claim
49 words
In a textile machine, an apparatus according to claim 1 and characterized further by a sleeve fixedly mounted to the spindle bank and characterized further in that said stator base includes a recess and said resilient member is snugly received within said recess and is mounted to said sleeve.
Claim 4
Dependent Claim
40 words
In a textile machine, an apparatus according to claim 2 and characterized further in that up to one-half of the extent of said resilient member, as measured with respect to the axis of said spindle, is received within said recess.
Claim 5
Dependent Claim
27 words
In a textile machine, an apparatus according to claim 2 and characterized further in that said resilient member is adhered to said sleeve and said stator base.
Claim 6
Dependent Claim
31 words
In a textile machine, an apparatus according to claim 2 and characterized further in that said stator base includes an interconnecting member for interconnecting said stator and said rotor supporting means.
