Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that protection scope of the present invention is not by the restriction of detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or its conversion will be understood to comprise the element or ingredient stated at such as " comprising " or " including " etc., and does not get rid of other element or other ingredient.
As depicted in figs. 1 and 2, damped sleeve according to the specific embodiment of the invention is non-integral type two-stage sleeve, concrete structure includes: ut socket 1 and be embedded in the screw sleeve 2 in this ut socket by own tension, during use, ut socket 1 overlaps upper locking nut, and screw sleeve 2 puts screw rod, after putting simultaneously, nut-screw is screwed in screw simultaneously, when after locking nut with end surface of screw hole laminating, continue to tighten until screw-down torque. it is rotating Vortex continuing the starting stage locking nut tightened with screw rod, moment of friction constantly increases, when the moment of friction of locking nut is less than the moment of friction of screw rod, continue to twist ut socket 1, screw sleeve 2 and ut socket 1 is made to occur reverse slide to adapt to the requirement that screw rod is motionless, realize locking nut and be tightened to regulation moment, screw-down torque now is equal to regulation moment+damping torque, achieve and be tightened nut-screw position and keep and tighten and reach regulation moment, can eliminate tighten locking nut moment with reverse screw rod moment superpose generation fictitious force square.
Wherein, as it is shown on figure 3, ut socket 1 is cylindrically, its inner chamber includes from right to left respectively: inner peripheral surface 12 corner apertures 11, cylindrical hole 12 and square opening 13.Wherein, inner peripheral surface 12 corner apertures 11 is for being set with locking nut adaptation and then being tightened. Cylindrical hole 12 is for holding the screw sleeve 2 being embedded in this ut socket by own tension. Square opening 13, for being connected with tightening tool, drives whole damped sleeve to tighten locking nut and screw rod. The diameter of inner peripheral surface 12 corner apertures 11 is more than the diameter of cylindrical hole 12, it is simple to screw sleeve 2 is slided into the position of cylindrical hole 12 by one end of inner peripheral surface 12 corner apertures 11 of ut socket 1.
As shown in Figure 4, screw sleeve 2 is cylindric in thin walled aperture, and inner peripheral surface has 12 corner apertures 21, and outer peripheral face is and the face of cylinder 22 of cylindrical hole 12 adaptation. Screw sleeve 2 is installed in the cylindrical hole 12 of ut socket 1 by after its opening radial compression, forms coaxial two-stage sleeve. Wherein, screw sleeve 2 is by the two ends flange axial limiting of cylindrical hole 12; Screw sleeve 2 is made the circumferential frictional damping of its cylindrical hole 12 with ut socket 1 keep the initial phase relationship (can measure) of certain moment values by self radial tension. Ut socket 1 overlaps upper locking nut, and screw sleeve 2 puts screw rod, after putting, nut-screw is screwed in simultaneously screw simultaneously, when after locking nut with end surface of screw hole laminating, continues to tighten until screw-down torque. It is rotating Vortex continuing the starting stage locking nut tightened with screw rod, moment of friction constantly increases, when the moment of friction of locking nut is less than the moment of friction of screw rod, continue to twist ut socket 1, screw sleeve 2 and ut socket 1 is made to occur reverse slide to adapt to the requirement that screw rod is motionless, it is achieved locking nut is tightened to regulation moment.
Before using, first cylindrical hole 12 position sliding into ut socket 1 after screw sleeve 2 radial compression. Install, measure screw sleeve 2 and the damping torque value of reverse slide occurs in cylindrical hole 12. During use, inner peripheral surface 12 corner apertures 11 of ut socket 1 overlaps upper locking nut, 12 corner apertures 21 of screw sleeve 2 put screw rod (when nut hexagonal and screw rod hexagonal phase place not coupler sleeve fine-tuning nut screw rod phase place), after putting simultaneously, 13 nut-screws of the square opening of driven at low speed damped sleeve screw in screw simultaneously, when after locking nut with end surface of screw hole laminating, continue to tighten until screw-down torque. It is rotating Vortex continuing the starting stage locking nut tightened with screw rod, moment of friction constantly increases, when the moment of friction of locking nut is less than the moment of friction of screw rod, continue to twist ut socket 1, screw sleeve 2 occurs reverse slide to adapt to the requirement that screw rod is motionless in cylindrical hole 12, realize locking nut and be tightened to regulation moment (screw-down torque is equal to regulation moment+damping torque), eliminate fictitious force square.
To sum up, this damped sleeve is the non-integral type two-stage sleeve that screw sleeve is embedded in ut socket by own tension, by making two-stage sleeve produce relative rotation when needed, it is tightened nut-screw position with realization to keep and tighten reaching regulation moment, can eliminate tighten locking nut moment with reverse screw rod moment superpose generation fictitious force square, and easy to use, service precision is high.
The aforementioned description to the specific illustrative embodiment of the present invention illustrates that and the purpose of illustration. These describe and are not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned instruction, it is possible to carry out much changing and change.
