Description

A kind of torsional rigidity regulating device

Technical field

The present invention relates to mechanical transmission fields, particularly relate to machine driven system design and field tests.

Background technology

In modern designs and test, often run into the problem about system torque transmission and the adjusting of its torsional rigidity.In engineering, conventionally adopt torsion spring or torque tube, torsion spring is generally standard component, and volume and torsional rigidity can not change, can only be by changing torsion spring or organizing torsion spring more and connect to realize torsional rigidity adjusting, installing space anxiety, changes operation loaded down with trivial details; Torque tube is generally system parts, and the manpower and materials that its design, calibration and replacing need to expend are large, and the cycle is long, does not advocate this type of design in design.Especially in engineering design and experimental stage, conventionally need to drivetrain rigidity repeatedly be regulated and be tested, to obtain meeting the rigidity value of system requirements, obtain thus the torsional rigidity value scope of system parts, as the design considerations of system parts, therefore, need one to get final product transmitting torque, can easily realize again the device that torsional rigidity regulates, improve design efficiency, reduce design cost, shorten the design cycle.

In addition, a kind of variable-stiffness helix torsion spring is disclosed in the patent application document that is 200610147349 at application number, by at least two, wait stiffness helix torsion spring to form, any one waits the two ends of stiffness helix torsion spring to be all provided with diametrically separately connecting pin, any one waits the diameter of stiffness helix torsion spring to be all less than or to be greater than the stiffness helix torsion spring such as any one remaining, etc. the coaxial fit of rigidity torque spring, the connecting pin of any one stiffness helix torsion spring such as grade all becomes to be greater than the angle of 0 degree with the connecting pin of any one remaining stiffness helix torsion spring such as grade, during work, the helix torsion spring of the low rigidity of minor diameter first works, remaining helix torsion spring works by rigidity hierarchal order, can obtain the family curve that becomes rigidity.The torque spring that this class becomes rigidity can only occur just to make spring rate change after certain torsional deflection, can not carry out torsional rigidity adjusting according to actual requirement, and this class variable rate spring be by etc. rigidity torque spring fit form, realize stiffness variation in a big way, must there be multiple helix torsion spring fits, the variable rate spring volume of composition is large, can not in less space, use.

Summary of the invention

Object of the present invention: overcome in prior art without both can transmitting torque, can easily realize again the equipment that torsional rigidity regulates and cause design and test efficiency low, operation is loaded down with trivial details, and cost is high, the problem that the cycle is long

Technical scheme of the present invention: for achieving the above object, the present invention processes a sub-end plate 2, female end plate 1 and a flexibility bar 3, sub-end plate 2 is truncated cone-shaped, centre is processed with round boss 5, female end plate is truncated cone-shaped, and there is annular boss 7 centre, and there is circular groove 6 at annular boss 7 middle parts, boss 5 and groove 6 coaxial cooperation, flexibility bar 3 is fixed in the draw-in groove 4 that sub-end plate 2 is corresponding with female end plate 1.

Torsional rigidity regulating device can connect use between two in turn.

The good effect that the present invention produces: the present invention by adding the method for many groups flexibility bar that can be for convenience detach between two end plates, realize moment of torsion transmission and torsional rigidity simultaneously, simple and reliable, easy to process, use easy and simple to handle, function easily realizes, and volume is small and exquisite, under various environment, thereby improve design and test efficiency, the operation that simplifies the operation, reduces experimentation cost, shortens design and test period.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.

The present embodiment is a kind of torsional rigidity regulating device, process a sub-end plate 2, female end plate 1 and a flexibility bar 3, sub-end plate 2 is truncated cone-shaped, centre is processed with round boss 5, female end plate is truncated cone-shaped, and there is annular boss 7 centre, and there is circular groove 6 at annular boss 7 middle parts, boss 5 and groove 6 coaxial cooperation, flexibility bar 3 is fixed in the draw-in groove 4 that sub-end plate 2 is corresponding with female end plate 1.

Flexibility bar 3 quantity are identical with the draw-in groove 4 on son, female end plate with cross-sectional shape.

Sub-end plate 2 installation parallel with female end plate 1 during use, stretches into the boss of sub-end plate 25 parts in the groove 6 at female end plate annular boss 7 middle parts, boss 5 and the mutual coaxial cooperation of groove 6.Flexibility bar 3 is embedded in the draw-in groove 4 that son, female end plate are corresponding and is fixing, parallel installation between two.Female end plate 1 and sub-end plate 2 are fixed and are remained unchanged apart from the position of transmitting linear system due to moment of torsion, flexibility bar 3 is because the effect of moment of torsion occurs bending and deformation, because its two ends are fixed on female end plate 1 and sub-end plate 2, therefore it also can produce stretcher strain, reduce the bending deformation quantity of flexibility bar 3 under same torque, thereby can improve torsional rigidity of the present invention, be particularly useful for using under heavy condition.

This torsional rigidity regulating device series connection access moment of torsion is passed in linear system, by increasing or dismantling flexibility bar 3, changed the number of flexibility bar 3 or the flexibility bar 3 of replacing different cross section, just can reach the object of easy adjustment system torsional rigidity.

Can will organize more the series connection of torsional rigidity regulating device use, the mounting means of each rigidity adjuster is identical with embodiment mono-, connects in turn more, thereby can increase the range of adjustment of system stiffness by organizing torsional rigidity regulating device.
