Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As depicted in figs. 1 and 2, be non-integral type two-stage sleeve according to the damped sleeve of the utility model detailed description of the invention, concrete structure comprises: ut socket 1 and the screw sleeve 2 be embedded in by own tension in this ut socket, 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, after locking nut and end surface of screw hole are fitted, continues to tighten until screw-down torque.Rotating Vortex at the starting stage locking nut continuing to tighten and 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, make screw sleeve 2 and ut socket 1 that reverse slide occur and adapt to the motionless requirement of screw rod, realize locking nut and be tightened to regulation moment, screw-down torque now equals regulation moment+damping torque, achieve to be tightened the maintenance of nut-screw position and to tighten and reach regulation moment, can eliminate and tighten locking nut moment and superpose with torsion screw rod moment and produce fictitious force square.
Wherein, as shown in Figure 3, cylindrically, its inner chamber comprises ut socket 1 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 be embedded in by own tension in this ut socket.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 greater than the diameter of cylindrical hole 12, is convenient to screw sleeve 2 is slided into cylindrical hole 12 position 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 the face of cylinder 22 with cylindrical hole 12 adaptation.Screw sleeve 2, by being installed in the cylindrical hole 12 of ut socket 1 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 the cylindrical hole 12 of itself and ut socket 1 keep the initial phase relationship of certain moment values (can measure) 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 screw simultaneously simultaneously, after locking nut and end surface of screw hole are fitted, continues to tighten until screw-down torque.Rotating Vortex at the starting stage locking nut continuing to tighten and 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, make screw sleeve 2 and ut socket 1 that reverse slide occur and adapt to the motionless requirement of screw rod, realize locking nut and be tightened to regulation moment.
Before using, first cylindrical hole 12 position sliding into ut socket 1 after screw sleeve 2 radial compression.Install, measure the damping torque value that reverse slide occurs screw sleeve 2 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 coupler sleeve (nut hexagonal and screw rod hexagonal phase place not fine-tuning nut screw rod phase place), after putting simultaneously, the square opening 13 of driven at low speed damped sleeve screws in screw nut-screw simultaneously, after locking nut and end surface of screw hole are fitted, continue to tighten until screw-down torque.Rotating Vortex at the starting stage locking nut continuing to tighten and 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, reverse slide is there is and adapts to the motionless requirement of screw rod in screw sleeve 2 in cylindrical hole 12, realize locking nut and be tightened to regulation moment (screw-down torque equals regulation moment+damping torque), eliminate fictitious force square.
To sum up, this damped sleeve is screw sleeve is embedded in ut socket non-integral type two-stage sleeve by own tension, produce relative rotation by making two-stage sleeve when needed, keep and tighten reaching regulation moment to realize being tightened nut-screw position, can eliminate and tighten locking nut moment and superpose with torsion screw rod moment and produce fictitious force square, and easy to use, service precision is high.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
