Abstract
An air bearing for a spinning- or a twisting ring suitable for use in the textile industry has a stator which is mounted on a spring-loaded damping absorber system. The absorber has a linear spring-curve in response to small deflections which rises progressively as the stator is further deflected.
Claims6
An air bearing for a spinning or twisting ring, comprising a bearing stator mounted on a resilient dampening receiver system whereby radial deflections of said stator result in corresponding deflections in said receiver system, and stopping means for limiting the radial vibration amplitudes of said stator, said stopping means cooperating with said receiver system to allow said receiver system to be completely, freely deformable within a small range of deflections and for larger deflections attains progressive rigidity and becomes only conditionally, freely deformable.
In an aerodynamic bearing for air cushion supporting of a spinning or twisting ring, both axially and radially,
- the combination with a stator and a rotor supported by and rotatable relative to said stator,
- of mounting means for said stator comprising stopping means and a resilient dampening absorber system cooperating with said stopping means to provide a characteristic spring-curve which is linear over a range of small radial deflections and thence rises progressively for larger deflections.
In an aerodynamic bearing for air cushion supporting of a spinning or twisting ring, both axially and radially, comprising a stator, a rotor supported by and rotatable relative to said stator, the improvement comprising:
- said rotor having an annular shape and including upper and lower radially extending projections;
- said stator having an annular shape and being disposed concentric to said rotor and including upper and lower radially extending projections, whereby said stator substantially engages said rotor to define a small air gap therebetween for the air cushion;
- mounting means for said stator comprising a resilient dampening absorber system including two resiliently flexible ring segments each having inside and outside radial surfaces and being oppositely disposed and substantially concentric relative to said stator, and connecting means operable to connect said stator to said ring segments to be supported thereby;
- whereby deflections of said stator result in corresponding deflections in said ring segments;
- and
- stopping means disposed in close proximity to the outside radial surface of said ring segments when at rest,
- said absorber system having a characteristic spring-curve which is linear for radial deflections until there occurs abutment between a portion of the outside radial surface of at least one of said ring segments with said stopping means and thence rises progressively for larger deflections.
