In prior art, mainly contain two kinds of forms about mechanical shaft seal, be using rotating ring bellows as a main power transmission member, the interference fit between carbon fiber teflon and the spring seat of filling by rotating ring bellows top is connected to transmit rotates.Such Placement makes other revolving parts have certain hysteresis quality with respect to bellows, and bellows easily twists and causes damage.Another kind is that silicon carbide moving ring assembly and the cold edge of carbon fiber teflon the mate-assist reinforcing device. that are filled in moving ring assembly top are further clamped.That above-mentioned which kind of structure all has weak heat-dissipating, the shortcoming that working life is short.
Model utility content
The purpose of this utility model be for the problems referred to above propose a kind ofly have that good heat dispersion, wear resistance are good, work long service life, the anti-good mechanical seal device of twisting off property.
For reaching this object, the utility model by the following technical solutions:
A kind of mechanical seal device, comprise rotating shaft, be arranged on stationary ring, moving ring assembly, rotating seat, spring seat in described rotating shaft, described stationary ring is arranged at the end of described rotating shaft, one side of described stationary ring is connected with described rotating seat, is provided with described moving ring assembly in described rotating seat; The arranged outside of described rotating seat has described spring seat, and the outside of described spring seat is fixedly connected with point half snap ring; Described spring seat is provided with hold-down ring away from one end of described stationary ring.
Preferably, between described spring seat and described rotating seat, be provided with and prevent the pin that rotates between described rotating seat and described spring seat.
Further, the inside of described spring seat is provided with spring, between described spring and described point of half snap ring, is disposed with spring washer and setting sleeve.
Preferably, described point of half snap ring is fixed on described spring seat by screw.
Preferably, described hold-down ring is fixed in described rotating shaft by fastening screw trip bolt.
Further, described moving ring assembly is bellows component, and the middle part of described moving ring assembly is polytetrafluoroethylbellows bellows.
Further, the two ends of described polytetrafluoroethylbellows bellows are all filled with respectively carbon fiber teflon and glass fibre.
The beneficial effects of the utility model are: the mechanical seal device in the utility model, and the outside of moving ring assembly does not arrange any parts, and thermal diffusivity is good, long service life; The structure that adopts moving ring assembly, stationary ring to be combined with, and be used in conjunction with point half snap ring and spring seat clamps moving ring assembly, in the time that rotating shaft is rotated, divide half snap ring to rotarily drive spring seat and further drive moving ring assembly rotation, rotation process transmission is more stable, be rigid of transmission owing to transmitting rotation process, the synchronism of therefore rotating between each component is good, effectively prevents that moving ring assembly twists off in rotation process.
