Abstract
The invention discloses an engine water pump sealing gasket which comprises a gasket body. A hole is formed in the gasket body, a protruding pillar is arranged in the hole in a penetrating mode, the sealing gasket is arranged between a water pump shell and a shaft sleeve, bosses are arranged at the upper end and the lower end of the sealing gasket, the bosses are connected with grooves in a matched mode, and arc grooves are formed in left arms and right arms of the bosses. According to the engine water pump sealing gasket, the detachable sealing gasket is arranged between the water pump shell and the shaft sleeve, and therefore the sealing effect can be achieved, and detachment is convenient.
Description
Technical field
The present invention relates to engine component technical field, especially relate to a kind of engine water pump packing.
Background technique
Automobile engine water pump shell is be cast into shaped piece by the gap between airtight two rigid pipes of rubber seal when water pump complement is connected with cylinder body, ensures that cooling liquid does not leak outside.Under normal circumstances, coat a kind of adhesive in order to adhering and sealing circle at pump case seal groove place, make seal ring difficult drop-off in the inversion of water pump complement, transport, assembly process, ensure the integrity of assembly.There is a drawback in this Placement, when assembly reveal be confirmed to be seal groove or seal ring cause need to change time, because of seal groove, place scribbles sealer, destroys embryonal structure pattern and seal ring, cannot change, cause overall waste, if sealant-coating is uneven, seal ring compressive strain is inconsistent, there is provided the passage of leakage will to the liquid in chamber or air, cause assembly to reveal on the contrary, existing a kind of problem in order to improve seal ring dismounting and change, but sealing effect is appointed so not so good.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of sealing gasket of engine water pump, it has sealing effect and feature easy to loading and unloading.
To achieve these goals, the technical solution adopted in the present invention is: a kind of sealing gasket of engine water pump, water pump cover is in one end of transmission shaft, transmission shaft is provided with the axle sleeve between water pump cover and transmission shaft, the inwall of described water pump cover and the outer wall of axle sleeve all offer groove, groove left and right two-arm is equipped with arc convex tendon, sealing gasket is provided with between described water pump cover and axle sleeve, sealing gasket upper and lower end is equipped with the boss be connected with groove fit, and the left and right two-arm of boss is equipped with the arc groove be connected with arc convex tendon.
Wherein, described sealing gasket comprises pad, and pad is offered porose, is equipped with projection in hole, and the cross section of described projection is circular, square or semicircle.
After adopting said structure, the present invention is compared to the prior art advantageously: its water pump cover is in one end of transmission shaft, transmission shaft is provided with the axle sleeve between water pump cover and transmission shaft, the inwall of described water pump cover and the outer wall of axle sleeve all offer groove, groove left and right two-arm is equipped with arc convex tendon, sealing gasket is provided with between described water pump cover and axle sleeve, on sealing gasket, lower end is equipped with the boss be connected with groove fit, the left and right two-arm of boss is equipped with the arc groove be connected with arc convex tendon, the present invention by arranging dismountable sealing gasket between water pump cover and axle sleeve, sealing effect can be reached and easy to loading and unloading.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is another structural representation of the present invention.
Embodiment
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
As shown in Fig. 1 and Fig. 2: a kind of sealing gasket of engine water pump, water pump cover 1 is in one end of transmission shaft, transmission shaft is provided with the axle sleeve 2 between water pump cover 1 and transmission shaft, the inwall of described water pump cover 1 and the outer wall of axle sleeve 2 all offer groove 3, groove about 3 two-arm is equipped with arc convex tendon 4, sealing gasket 5 is provided with between described water pump cover 1 and axle sleeve 2, on sealing gasket 5, lower end is equipped with the boss 6 be connected with groove 3, the left and right two-arm of boss 6 is equipped with the arc groove 7 be connected with arc convex tendon 4, in addition, described sealing gasket also can be arranged to comprise pad by the present invention, pad is offered porose, projection is equipped with in hole, the cross section of described projection is circular, square or semicircle, the present invention by arranging dismountable sealing gasket 5 between water pump cover 1 and axle sleeve 2, sealing pad 5 upper, lower two ends are equipped with boss 6 and are connected with groove 3, in addition, the left and right two-arm of boss 6 is equipped with the arc groove 7 be connected with arc convex tendon 4, arc groove 7 is connected with the arc convex tendon 4 of groove about 3 two-arm, such connection closely can reach sealing effect and easy to loading and unloading.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
Claims (2)
