Fig. 2 is the structural representation of another kind of mode of execution of the damping rotary shaft device of prior art;
Fig. 3 is the structural representation of a kind of mode of execution of minisize damping rotary shaft device of the present invention;
The structural representation of the another kind of mode of execution of Fig. 4 minisize damping rotary shaft device of the present invention.
Embodiment
Referring to Fig. 3, minisize damping rotary shaft device of the present invention comprises rotating shaft 1, and the axle journal of rotating shaft 1 is by forming with rotating shaft 1 semicolumn spindle nose 6 that is connected as a single entity and the elastic device of adorning thereon, and semicolumn spindle nose 6 and elastic device are inserted in the axle sleeve 2.
Elastic device is the spring sheet 3 of arch, the outer end of spring sheet 3 withstands on the madial wall of axle sleeve 2, the inner end of spring sheet 3 withstands on the semicolumn spindle nose 6 of rotating shaft 1, and the outer surface of spring sheet 3 is the concentric disc that matches with the madial wall of axle sleeve 2 with the semi-circle outer surface of the semicolumn spindle nose 6 of rotating shaft 1.
During installation, spring sheet 3 is placed on the semicolumn spindle nose 6 of rotating shaft 1, tightens up the external diameter of spring sheet 3 then, be inserted into together in the axle sleeve 2, rely on spring sheet during use and shrink the radial force that produces, the axle journal drive fit of axle sleeve 2 and rotating shaft 1, used a period of time after, though the axle journal of rotating shaft 1 and axle sleeve 2 inwalls also have wearing and tearing, but the elastic force of spring sheet 3 remains unchanged substantially, can continue to keep damping function, thereby has prolonged the working life of turning gear greatly, and it is simple in structure, easy to use.
Referring to Fig. 4, minisize damping rotary shaft device of the present invention comprises rotating shaft 1, and the axle journal of rotating shaft 1 is made up of the semi-cylindrical shaped spindle nose 7 and the bearing shell 4 that are connected as a single entity with rotating shaft 1, be provided with spring 5 between semi-cylindrical shaped spindle nose and the bearing shell 4, semi-cylindrical shaped spindle nose 7 and bearing shell 4 are inserted in the axle sleeve 2.
