Abstract
The utility model relates to a torsion-free mechanical sealing device comprising static rings, a dynamic ring corrugated pipe assembly, a spring seat and a rotating shaft, wherein two ends of the rotating shaft are respectively provided with the static rings, and the inner side of the spring seat installed on the rotating shaft is provided with the dynamic ring corrugated pipe assembly; and a bisection snap ring is arranged outside and connected with the dynamic ring corrugated pipe assembly through a screw nail, and a locating sleeve is clamped between the bisection snap ring and a spring shim. The torsion-free mechanical sealing device has the advantages of good heat dispersion, low wear rate, long service life and reliable transmission; the corrugated pipe and the rotating shaft are tightly clamped by the bisection snap ring by adopting the structure combining the static rings with the dynamic ring; and when the rotating shaft rotates, the bisection snap ring rotates and drives the spring seat through the screw nail so that the rotary spring seat can drive the dynamic ring to rotate through the interference fit between the dynamic ring assembly and the spring seat as well as a tally pin filled with polytetrafluoroethylene, and the transmission mode adopts rigid transfer and can well achieve the synchronous rotation of each component, thereby being capable of preventing torsion.
Description
Technical field
The utility model relates to a kind of mechanical shaft seal device, relates in particular to a kind of anti-mechanical seal device that twists off.
Background technique
Two kinds of mechanisms are generally adopted in the existing mechanical shaft sealing, the first adopts whole rotating ring bellows, the top is the filling carbon fiber teflon, the pure teflon of middle employing, afterbody is the filled glass fiber teflon, connect by interference fit between the carbon dimension teflon that fill at the top and the spring seat, quiet of rotating ring bellows and rotating shaft interference fit, with dividing half snap ring to clamp, like this when rotating shaft is rotated, mainly come transferring power to use rotating ring by bellows, spring seat, the rotation of spring rotary member, because the relative bellows of other revolving part all has certain hysteresis quality, will make the bellows phenomenon that twists like this, can make spring fall shape when serious, finally make seal failure; In addition, because the filling carbon fiber teflon, its heat conductivity is lower, and radiating effect is relatively poor, when temperature is higher temperature deformation bigger, along with the rising of temperature, the pressure medium that mechanical seal can seal reduces rapidly; It two is cold edges of filling carbon fiber teflon that moving ring assembly adopts silicon carbide and rotating ring bellows top, further clamps being aided with the clamping circle, is connected by interference between clamping circle and the spring seat.More than two kinds of common structure common drawback be to use the life-span short, radiating effect is relatively poor.
The model utility content
At above defective, the purpose of this utility model provides that a kind of heat dispersion is good, wear rate is low, the anti-mechanical seal device that twists off of long service life, reliable transmission, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of anti-mechanical seal device that twists off comprises stationary ring, rotating ring bellows component, spring seat, rotating shaft, and described rotating shaft two ends are respectively equipped with stationary ring, and the inboard that is installed on the spring seat in the rotating shaft is provided with the rotating ring bellows component; The described rotating ring bellows component outside is provided with branch half snap ring and connects by screw, accompanies setting sleeve between described branch half snap ring and the compression spring.
The beneficial effect of the anti-mechanical seal device that twists off described in the utility model is: have that heat dispersion is good, wear rate is low, an advantage of long service life, reliable transmission; The structure that adopts dynamic and static loops to close makes branch half snap ring that bellows and rotating shaft are clamped, when rotating shaft is rotated, divide the rotation of half snap ring and pass through the screw belt flexible spring seat, the spring seat running drives the rotating ring rotation by the junction of the edges of two sheets of paper pin of filled polytetrafluoroethylene and the interference fit joint of spring seat and moving ring assembly, this kind of drive is a rigid of transmission, can well reach the synchronism of each component rotation, can prevent to twist off.
