Description
Technical field
The present invention relates to a kind of measurement mechanism, especially a kind of radial graphite-seal ring elasticity measuring device.
Background technology
Radial graphite-seal ring is dynamic sealing assembly conventional in mechanical system, the sealing at the input that the speed that is applicable to is higher, output shaft position.Its principle of work is pressed against on input, the output shaft sealing diameter of axle by the graphite block of several arcs by circumferential spring, plays radial seal effect; By end face spring, each piece of graphite block is pressed against on seat end surface simultaneously, prevents the lubricating oil spilt along the space between each piece of graphite block from releasing.Like this, when axle and graphite-seal ring relatively rotate, play good motive seal effect.
The elastic force of the circumferential spring in graphite grazing ring assemblies is larger on sealing property impact.Traditional control method controls elastic force in spring part design, but due to existence processing between each spare part and assembling equal error, the elasticity difference of actual graphite annulus assembly is comparatively large, and cause sealing property in use very unstable, oil spill rate is higher.Therefore in the urgent need to a kind of device radial graphite-seal ring elasticity being carried out to quantize to check.
Summary of the invention
The object of the present invention is to provide the flexible device of the radial graphite-seal ring of a kind of Measurement accuracy, this device can realize carrying out measures of quantization to radial graphite-seal ring elasticity.
Concrete technical scheme of the present invention is: measurement mechanism comprises base, rotating shaft, roller, gear, index dial, pointer, retainer, described rotating shaft is arranged on base by bearing, be provided with in rotating shaft internal tooth and and gears meshing, retainer is connected on base, gear is arranged on retainer, the installation shaft of gear is fixed with pointer, retainer is fixed with the index dial corresponding with the position of pointer, rotating shaft is outside equipped with the uniform roller of being located by retainer, the outline of rotating shaft is provided with identical with roller quantity, the plane that uniform and parameter is consistent, described plane and the axis being parallel of rotating shaft, described roller all contacts with the outline of rotating shaft, and all rollers can coordinate and are arranged in graphite-seal ring, measurement mechanism is also provided with the Jia Niu mechanism that rotating shaft is rotated.The outline of described rotating shaft is regular polygon, and described Jia Niu mechanism comprises steel wire, pallet, pulley, and pulley is fixed on base, and steel wire one end is fixed on the non-axle center place of rotating shaft, and the other end is fixed with pallet by pulley.
Present invention uses countershaft and apply moment of torsion to overcome the method for seal elastic force, and utilize gear drive principle to be exaggerated the subtle change of shaft rotary corner, utilize plane when its certain point outer rotates simultaneously, the principle that in plane, difference is different from the distance of certain point, by being several facets equally distributed in the registration interface designs of rotating shaft and roller, the elastic force of radial graphite-seal ring is directly reflected by the rotation amount of rotating shaft, the elasticity number of radial graphite-seal ring can be drawn by the relation that arranges of parameter.
