Abstract
The utility model provides a kind of double-end face sealing mechanism, comprising: fixed on the screw rod of equipment shell outer wall;First static ring is sleeved on rotating shaft and passes through screw rod, first static ring is locked by nut and is adhered to on equipment shell outer wall, and the sealing filler on first static ring is tightly contacted with the outer circular surface of rotating shaft and is sealed;Dynamic ring is tightly sleeved on rotating shaft and rotates with rotating shaft, and the end surface of dynamic ring close to equipment shell is tightly adhered with the end surface of sealing filler on first static ring;Second static ring is sleeved on rotating shaft and passes through screw rod, second static ring is locked by nut, so that the end surface of sealing filler on second static ring is tightly adhered with the end surface of dynamic ring away from equipment shell, and the sealing filler on second static ring is tightly contacted with the outer circular surface of rotating shaft and is sealed.Double-end face sealing is carried out to the gap between equipment shell and rotating shaft, and the sealing effect is good, and the anti-deflection effect is good, the service life is long, and the installation is convenient.
