Abstract
The utility model relates to a sealing element for a gear pump or a motor. The sealing element is characterized in that a seal groove is disposed on the rear end face of a front cover and is internally provided with a seal spacer, the end of the seal spacer is tightly fit with the periphery of the seal groove, the cross section of any part at the end of the seal spacer is inverted L-shaped, the inner side of the seal spacer is provided with a seal check ring, and the surface of the inner side of the seal spacer is tightly fit with the surface of the outer side of the seal check ring. The sealing element adopts the working principle as follows: during assembling, the seal spacer and the seal check ring are disposed in the seal groove of the front cover, and the front cover is disposed on a pump body, so that the end of the seal spacer is tightly fit with the periphery of the seal groove, the seal spacer and the seal check ring can be still buckled at a buckling part of the seal groove even if the seal spacer on the front cover is downwards faced, and the seal spacer and the seal check ring are hard to separate from the seal groove. The sealing element is convenient to install, and the seal spacer and the seal check ring are hard to separate from the seal groove, so that the assembly work performance and the work efficiency of the gear pump or the motor can be effectively improved.
Description
Technical field
The utility model relates to construction machinery industry, the Sealing of a kind of specifically gear pump and motor, and being applied to building machinery, lathe, farm machinery etc. is main engineering machinery.
Background technique
Gear pump of the prior art or motor are when assembling, generally be upwards to be placed on bonnet on the horizontal plane, and load onto various major parts successively by its upper edge one definite sequence, when protecgulum is installed, generally be earlier gasket seal, Sealing shield ring to be packed in the seal groove of protecgulum, for this reason, in the installation of postorder, gasket seal and Sealing shield ring are easy to deviate from seal groove, be difficult to while using finger to stop it to deviate to carry out assembling work, in case gasket seal and Sealing shield ring are deviate from seal groove, then the efficiency of assembling of gear pump or motor greatly reduces.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, the Sealing of a kind of gear pump and motor is provided, the technological scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises protecgulum, gasket seal, Sealing shield ring, the ear end face that it is characterized in that protecgulum is provided with seal groove, be provided with gasket seal in the seal groove, fit tightly around the end of gasket seal and the seal groove, the random position section of gasket seal end is L shaped, the inboard of gasket seal is provided with Sealing shield ring, and the inner surface of gasket seal and the outer surface of Sealing shield ring fit tightly.
Working principle and operation instruction: the gasket seal of the protecgulum of packing in the utility model changes form in the past, is processed into the gasket seal that fastens with seal groove.The end of gasket seal is radial and extends to and the position protecgulum seal groove and that connect.On the other hand, the seal groove that is equipped with on the protecgulum of sealing pad then forms and the corresponding shape of the plane shape of gasket seal, and groove depth is roughly corresponding with the thickness of gasket seal.Adopt this structure, then in assembling, earlier gasket seal, Sealing shield ring are installed in the seal groove of protecgulum, again protecgulum is installed on the pump housing, like this, makes the end of gasket seal and seal groove fit tightly all around, thereby behind the Sealing shield ring of packing into, even with the gasket seal on the protecgulum down, gasket seal, Sealing shield ring are still remained on the buckling part of seal groove by fastening, are not easy to take place the phenomenon of gasket seal, Sealing shield ring disengaging seal groove.Like this, effectively raise the operation and the operating efficiency of gear pump assembling.
The beneficial effects of the utility model are, the utility model is convenient to be installed, and gasket seal and Sealing shield ring can not thrown off in seal groove easily, effectively raise operation and working efficiency that gear pump or motor assemble.
