Arcuation；
The barreled tooth flank outside circle of barreled tooth flank outer spherical pivoting support and the straight-tooth tooth root on interior spherical straight-tooth outer ring
Circle uses matched in clearance connection centering, has certain running clearance, Internal Spherical Surface and ectosphere between barreled tooth flank and straight-tooth
There is also gap between face, owing to barreled tooth flank is in straight-tooth, in the case of having running clearance, axis can
To swing, the size of its angle △ a swung, relevant with running clearance size, such barreled tooth flank outer spherical is returned
Turning supporting and just can produce axis angle displacement on interior spherical straight-tooth outer ring, backlash is the biggest, axis angle
Degree displacement is the biggest；
Described centering is exactly the barreled tooth flank outside circle of barreled tooth flank outer spherical pivoting support and interior spherical straight-tooth outer ring
On straight-tooth root circle use matched in clearance connection；
Described sideshake refers to the gap between barreled tooth flank and straight-tooth, and displacement angle is directly proportional to sideshake, sideshake
The biggest, axis angle displacement angle is the biggest；
Test draws, barreled tooth flank outer spherical pivoting support axis in the range of 360 ° in interior spherical straight-tooth outer ring
Can realize angular displacement to swing, between angle △ a size and barreled tooth flank and the straight-tooth of swing, the size of sideshake has
Closing, they direct proportionality, sideshake is typically conjugated by tooth and obtains；
Gap between spherical in barreled tooth flank outer spherical face and straight-tooth, draws gap one through test of many times
As in the range of 0.3mm～0.5mm, it be by inner sphere radius SR-spherical outside surface radius SR is outer and obtains；
And general pivoting support includes outer ring, rolling element, spacing block, band, inner ring, rotor
Being bound up on one by screw and pivoting support inner ring, pivoting support outer ring is arranged on fixed body by screw
On, this pivoting support structure, pivoting support and rotor can only realize rotate, carrying, its axis is not
Angular displacement can occur, it is impossible to meet large-scale engineering machinery under special operation condition movable to the axis of pivoting support
Requirement；
The beneficial effects of the utility model are in sum: simple in construction, easy to use, meet extraordinary work
Under condition, large-scale engineering machinery has the requirement of axis angle displacement to pivoting support, it is achieved be arranged on axis angle displacement
In the upper engineering machinery of Intelligent rotary supporting two union bodies can in the range of 360 ° axis angle wobble, protect
Hold pivoting support raceway to carry all the time uniformly, improve the fatigue life of raceway, make up engineering machinery work
Environment is not enough and affects the defect in pivoting support service life.
