Abstract
The invention relates to a spinning or twisting machine with a plurality of upright textile spindles, wherein the spindle shaft of each textile spindle is coaxially firmly attached to the rotor shaft of an electromotor and wherein the housing of the electromotor includes upper and lower bearing brackets that are disposed on a spindle rail and for the purpose of simple and precise centering of the electromotor housing these bearing brackets are radially adjustable on the spindle rail independently of one another.
Claims7
A spinning or twisting machine comprising:
- a spindle rail having a linear axis, said spindle rail including an upper opening and a lower opening coaxial with the linear axis,
- a textile spindle disposed in an upright position on said spindle rail,
- a rotatable shaft cooperating with the textile spindle,
- an electromotor disposed within said spindle rail and having a rotor shaft driven by the electromotor, said rotor shaft being connected with said rotatable shaft to drive said textile spindle,
- an upper bearing bracket and a lower bearing bracket of the electromotor disposed on said spindle rail,
- said upper bracket being connected to said spindle rail by at least one elastic member,
- said lower bearing bracket including a dependent rigid tang,
- said rigid tang extending into a cup that protrudes through said lower opening in said spindle rail and is radially adjustable relative to said lower opening,
- an elastomeric holder ring interposed between said lower bearing bracket and said cup,
- a damping means including oil as a damping medium disposed in said cup for reducing oscillations of said electromotor and said spindle shaft,
- a ring disposed on a ring rail with the spindle passing coaxially through the ring,
- said upper and lower bearing brackets are disposed on the spindle rail and are adjustable in position radially on all sides independently of one another relative to said spindle rail.
A method for adjusting the textile spindles of a ring spinning or twisting machine comprising the steps of:
- (a) positioning a spindle rail adjacent to a textile machine, said spindle rail having upper and lower means defining openings therein,
- (b) assembling upper and lower bracket members on the opposite end walls of an electromotor supportive of a spindle shaft,
- (c) attaching an upper holder ring to said upper bracket member, said holder ring having an extent sufficient to cover the upper opening in said spindle rail,
- (d) inserting said electromotor and its attached brackets and holder ring into said upper opening in said spindle rail,
- (e) assembling lower holder rings carried by said electromotor to the lower opening in said spindle rail,
- (f) fastening in proper vertical orientation said spindle shaft by means of said upper holder ring to said spindle rail, and
- (g) adjusting the spindle shaft by securing the lower holder rings to said lower spindle rail.
