Abstract
The invention relates to an elastic measuring device for a radial graphite sealing ring. The elastic measuring device comprises a base, a revolving shaft, rollers, a gear, a dial, a needle pointer and a cage, wherein the revolving shaft is arranged on the base through a bearing; the rollers which are distributed uniformly through the cage are arranged outside the revolving shaft; the outline of the revolving shaft is provided with planes which are of the same quantity as the rollers, are distributed uniformly, and have consistent parameters; all rollers can be arranged in the graphite sealing ring in a matching way; and the measuring device is further provided with a twisting mechanism for rotating the revolving shaft. A method for overcoming the elastic force of a sealing piece by applying a torque to the revolving shaft is used, and small change of the rotation angle of the revolving shaft is amplified by using a gear transmission principle, so that the elastic force of the graphite sealing ring is directly reflected through the rotation amount of the revolving shaft, and an elastic value can be calculated through the setting relation of parameters.
Description
Technical field
The present invention relates to a kind of measurement mechanism, especially a kind of radially graphite-seal ring elasticity measuring device.
Background technology
Radially graphite-seal ring is dynamic sealing assembly commonly used in the mechanical system, the sealing at the input that the speed that is applicable to is higher, output shaft position.Its principle of work is to be pressed against on input, the output shaft sealing diameter of axle by the graphite block of circumferential spring with several arcs, plays the radial seal effect; By the end face spring each piece graphite block is pressed against on the bearing end face simultaneously, prevents from releasing along the lubricating oil that the space between each piece graphite block spills.Like this, when axle and graphite-seal ring relatively rotate, play good motive seal effect.
The elastic force of the circumferential spring in the graphite grazing ring assemblies is larger on the sealing property impact.Traditional control method is to control elastic force in the spring part design, but owing to have processing and assembling equal error between each spare part, the elasticity of actual graphite annulus assembly differs larger, and sealing property is very unstable in causing using, and oil spill rate is higher.Therefore in the urgent need to a kind of device that graphite-seal ring elasticity is radially quantized to check.
Summary of the invention
The object of the present invention is to provide the radially flexible device of graphite-seal ring of a kind of Measurement accuracy, this device can be realized graphite-seal ring elasticity is radially carried out measures of quantization.
Concrete technical scheme of the present invention is: measurement mechanism comprises base, rotating shaft, roller, gear, index dial, pointer, retainer, described rotating shaft is installed on the base by bearing, be provided with internal tooth in the rotating shaft and mesh with gear, retainer is connected on the base, gear is installed on the retainer, be fixed with pointer on the installation shaft of gear, be fixed with the index dial corresponding with the position of pointer at retainer, rotating shaft is outside equipped with the uniform roller by the retainer location, it is identical with roller quantity that the outline of rotating shaft is provided with, the plane uniform and parameter is consistent, described plane is parallel with the axis of rotating shaft, described roller all contacts with the outline of rotating shaft, and all rollers can cooperate and are installed in the graphite-seal ring, also are provided with on the measurement mechanism to make adding of rotating shaft rotation turn round mechanism.The outline of described rotating shaft is regular polygon, and described adding turned round mechanism and comprise steel wire, pallet, pulley, and pulley is fixed on the base, and steel wire one end is fixed on the place, non-axle center of rotating shaft, and the other end is fixed with pallet by pulley.
The present invention has used countershaft to apply the method that moment of torsion overcomes seal elastic force, and utilize the gear drive principle to amplify the subtle change of shaft rotary corner, certain is put when rotating outside it to utilize simultaneously the plane, the difference principle different from the distance of certain point on the plane, be equally distributed several facets by the registration interface designs at rotating shaft and roller, make radially that the elastic force of graphite-seal ring directly reflects by the rotation amount of rotating shaft, the relation that arranges by parameter can draw the radially elasticity number of graphite-seal ring.
