Abstract
In an open-end spinning device with a spinning rotor whose shaft bears axially upon the ball of a step bearing, said step bearing is designed for the attenuation of axial oscillations and shocks of the spinning rotor. The bearing includes an elongated housing provided with a ball supporting member and a resilient member.
Claims3
A step bearing for use in an open-end spinning device having a plurality of spinning stations,
- a spinning rotor having a shaft extending rearwardly therefrom comprising:
- a ball,
- ball support means mounted on said spinning machine for supporting said ball and receiving oscillations from said spinning machine which cause said ball to rotate in said support means,
- an end of said rotor shaft engaging one side of said ball,
- resilient means formed of an elastomeric material for engaging said ball support means on a side opposite said shaft for axially damping any axial oscillations imparted to said ball by said shaft,
- said ball support means including,
- an elongated housing carried on a side of said ball opposite said shaft of said rotor,
- a tubular cylindrical bore provided in said housing having an open-end, a side wall and a bottom surface,
- said resilient means having first and second ends carried in said bore with said first end abutting said bottom surface of said tubular bore,
- a ball receiver carried in said bore in abutting relation with said second end of said resilient means, and
- said resilient means having a diameter less than the diameter of said cylindrical bore so that said resilient means when radially expanded by axial force imparted by said shaft is in a non-damping capacity in the radial direction.
