Abstract
A textile spindle for treating textile or the like, the spindle including a shaft driven by an individual motor. The rotor of the motor is on the shaft. A double row bearing includes an inner ring on the shaft. An outer ring of the bearing is supported in the spindle housing by two axially spaced apart rubber/metal elements. Two additional elastic damping elements attach the spindle housing to a spindle bearing plate. The motor stator is supported in a motor housing attached stationary with the spindle housing.
Claims9
A spindle for treatment of textile, or the like, and an individual motor for driving the spindle;
- the spindle comprising an elongate shaft including means thereon for acting on textile material;
- means for shaft for defining two axially spaced apart inner races of a double row bearing;
- an outer ring radially outside each inner race;
- bearing elements disposed between each inner race on the shaft and each outer ring of the double row bearing;
- a spindle housing disposed around the outer ring of the double row bearing;
- a respective pair of rubber/metal elements disposed at axially spaced apart locations and disposed radially between the outer ring and the spindle housing for supporting and damping vibration of the outer ring in the spindle housing;
- the motor including a rotor which is carried on the shaft and rotates together with the shaft;
- the motor further comprising a stator supported around the rotor;
- spindle bearing means comprising a spindle bearing plate;
- means on a housing of the motor for fastening the spindle to the spindle bearing plate vibrational damping elements between the spindle housing and the spindle bearing plate;
- and fastening means for fastening the spindle housing to the spindle bearing plate through the vibration damping elements.
