Embodiment
In order to make the object of the invention, technological scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.As depicted in figs. 1 and 2; The rock-steady structure of a kind of rotatingshaft that the embodiment of the invention provides; Comprise and be arranged in a stationary housing 100 and extend the rotatingshaft 200 outside the said stationary housing 100; Said rock-steady structure also comprises and is sheathed on the said rotatingshaft 200 and elastic damping member 300 that the said rotatingshaft 200 of may command rocks and can said elastic damping member 300 be pressed in the pressed component 400 on the said stationary housing 100, is fixedly connected between said pressed component 400 and the said stationary housing 100.Through rotatingshaft 200 being arranged in the lower elastic damping member 300 of hardness; Can effectively prevent the vibration of rotatingshaft 200; Improved the stationarity that rotatingshaft 200 rotates; With compare through the method for on gear, adding the bigger damping oil of viscosity in the existing technology, the rock-steady structure of a kind of rotatingshaft that the embodiment of the invention provides, its vibration-isolating effect is good, low to the product seal request, product structure simple, assembling easily, cost of production is low; And the kinetic energy rejection of rotatingshaft 200 is little, need not use damping oil can guarantee rotatingshaft 200 smooth rotation, and maintenance and user cost are low.
Particularly; As shown in figures 1 and 3; The through hole that said elastic damping member 300 is sheathed on the said rotatingshaft 200 is the polygonal through hole 301 that is cut in said rotatingshaft 200 peripheries outward; For line contacts, reduced the effective area of contact of elastic damping member 300, thereby reduced the frictional force between elastic damping member 300 and the transmission shaft between the polygonal through hole 301 of the external diameter of rotatingshaft 200 and elastic damping member 300 with rotatingshaft 200.Simultaneously; Owing to have certain clearance between polygonal through hole 301 and the rotatingshaft 200; Just can form certain space that can tolerant elastic damping member 300 distortion, thereby can further absorb and the impact force of rotatingshaft 200 when cushioning transmission, make that the stationarity of running of rotatingshaft 200 is better.
As shown in Figure 2, polygonal through hole 301 according to the invention is regular hexagon or octagon preferably, so that rotatingshaft 200 is stressed even, improves the stability that rotatingshaft 200 rotates.More specifically, said pressed component 400 is fixed on the said stationary housing 100 through the locking element (not shown), and is easy for installation.
More specifically; As depicted in figs. 1 and 2, said pressed component 400 comprise can ccontaining said elastic damping member 300 holding cavity 302, with fixing elastic damping member 300 reliably; Prevent that elastic damping member 300 from coming off from pressed component 400; One end face of said holding cavity 302 offers the perforation 401 that can supply rotatingshaft 200 to wear, and the other end of said holding cavity 302 convexes with and is used for the flange that is connected with stationary housing 100, offers the attachment hole 402 that can supply locking element to wear on the flange.
Further, as depicted in figs. 1 and 2, the outside of said elastic damping member 300 is provided with tapering; The sidewall of said holding cavity 302 is provided with the tapering that the outside with said elastic damping member 300 is complementary; Like this, the compressing degree of 400 pairs of elastic damping members 300 of the tight member of scalable makes the 301 inboard radially drum type distortion that produce in various degree of polygonal through hole; Thereby the frictional force of 300 pairs of rotatingshafts 200 of can regulate elastic damping member; Guaranteeing that rotatingshaft 200 under not vibrative prerequisite, can be adjusted to minimum with the frictional force of 300 pairs of rotatingshafts 200 of elastic damping member, further to avoid the kinetic energy rejection of rotatingshaft 200.
Preferably, said pressed component 400 adopts the metallic material impact briquetting, to improve the structural strength of pressed component 400.Preferably, said elastic damping member 300 adopts the rubber material manufacturings, utilized that the rubber material material is softer and wear-resisting, the elastic deformability strong, and rotatingshaft 200 between the little characteristic of friction factor, improved reliability of structure.
Preferably, said locking element is a bolt, is convenient to the dismounting of pressed component 400 and is convenient to adjust the compressing degree of 400 pairs of elastic damping members 300 of pressed component.
Particularly; As shown in Figure 1; Said elastic damping member 300 is sheathed on the two ends of said rotatingshaft 200, and said elastic damping member 300 and pressed component 400 all are located at the outside of stationary housing 100, and pressed component 400 assembles simply, is easy to install with elastic damping member 300.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
