Preferably, the cross section of quiet sealing washer is trapezoidal, two ring channels, two have been seted up to the circumference wall of quiet sealing washer the inside of ring channel is all fixed and is equipped with the assistance sealing washer, the lateral wall of first seal groove is seted up and is assisted sealing washer matched with second seal groove.
Preferably, the inner diameter of the static sealing ring is 44mm, and the outer diameter of the static sealing ring is 50 mm.
Preferably, the upper side and the lower side of the end cover are fixedly arranged at the right end of the hydraulic oil cylinder through fastening bolts.
Preferably, the cross section of the auxiliary sealing ring is circular.
Preferably, the static sealing ring and the auxiliary sealing ring are both made of natural rubber.
Compared with the prior art, the utility model provides a static sealing washer of heavy machinery hydraulic cylinder end cover possesses following beneficial effect:
1. the static sealing ring of the end cover of the hydraulic cylinder of the heavy machinery can ensure the sealing property between the end cover and the hydraulic cylinder through the static sealing ring arranged between the end cover and the hydraulic cylinder.
2. This heavy machinery hydraulic cylinder end cover static seal circle adopts trapezoidal shape and all is provided with the assistance sealing washer on the circumference wall through static seal circle, can increase the sealed effect between end cover and the hydraulic cylinder.
The part that does not relate to in the device all is the same with prior art or can adopt prior art to realize, the utility model discloses can guarantee the leakproofness between end cover and the hydraulic cylinder to avoid the phenomenon that liquid spills over.
