Abstract
The utility model discloses a crankcase cover of an internal combustion engine. The crankcase cover of the internal combustion engine comprises a body. The surface of the body is composed of two end faces and a side face connected with the two end faces, the body is provided with a stepped hole used for a power-output shaft of the internal combustion engine to penetrate, the stepped hole includes a bearing hole, an oil seal hole and a water seal hole coaxially connected in sequence, an air vent on the surface of a through body is arranged on a hole wall between the oil seal hole and the water seal hole. When the crankcase cover of the internal combustion engine is assembled, two end faces of the body are respectively fixedly connected with a box of a crankcase of the internal combustion engine and a casing of a centrifugal pump, the power-output shaft of the internal combustion engine penetrates through and then extends out of the bearing hole, the oil seal hole and the water seal hole, water flowing through the centrifugal pump can carry away heat of the crankcase cover of the internal combustion engine, and operation temperature of the internal combustion engine is lowered. The crankcase cover of the internal combustion engine and a pump cap of the centrifugal pump are combined together, assembling efficiency of the crankcase cover of the internal combustion engine and the centrifugal pump can be improved, the crankcase cover of the internal combustion engine is small in processing amount, low in cost, compact in structure and convenient to move.
Description
Technical field
The utility model relates to field of internal combustion engine, refers in particular to a kind of crankcase cover of internal combustion engine of internal-combustion engine direct connected centrifugal pump unit.
Background technique
The internal-combustion engine direct connected centrifugal pump unit of motor mainly comprises crank case of internal combustion engine, internal combustion engine moving power output shaft and centrifugal pump etc.; The impeller of centrifugal pump directly is installed on the internal combustion engine moving power output shaft; The pump cover of centrifugal pump is installed on the crankcase cover of internal combustion engine, and the pump case of centrifugal pump is installed on the pump cover of centrifugal pump again.
But existing crank case of internal combustion engine and centrifugal pump are two separate structures, need the pump cover of crankcase cover of internal combustion engine and centrifugal pump be bound up, and that is to say that need carry out secondary installing could be assembled together crank case of internal combustion engine and centrifugal pump.
The model utility content
In view of this, the purpose of the utility model is to provide a kind of efficiency of assembling that can improve again can cost-effective crankcase cover of internal combustion engine.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of crankcase cover of internal combustion engine; Comprise body; The surface of this body is made up of with the side that is connected both ends of the surface both ends of the surface; Said body is provided with the shoulder hole that is used to wear the internal combustion engine moving power output shaft, and this shoulder hole comprises the coaxial bearing hole, oil sealing hole and the water seal hole that are connected successively, and the hole wall between this oil sealing hole and this water seal hole is provided with the vent that connects body surface.
The aperture in said bearing hole, said oil sealing hole and said water seal hole is by large and small and variation greatly successively.
Said vent connects the said side of body.
In said bearing hole, said oil sealing hole and the said water seal hole respectively correspondence be provided with bearing, oil sealing and water seal.
After adopting said structure; The crankcase cover of internal combustion engine of the utility model has following beneficial effect: during assembling; One end face of body and the casing of crank case of internal combustion engine are affixed; The housing of the other end of body and the centrifugal pump of internal-combustion engine is affixed, and the internal combustion engine moving power output shaft stretches out after passing bearing hole, oil sealing hole and water seal hole successively; Water that from centrifugal pump, leaks and the machinery oil that from crank case of internal combustion engine, leaks discharge through vent, and the water that flows through centrifugal pump can be taken away the heat of crankcase cover of internal combustion engine, has reduced the operating temperature of internal-combustion engine; The utility model has reduced by a lid, and the pump cover that is about to crankcase cover of internal combustion engine and centrifugal pump unites two into one, and can improve the efficiency of assembling of crank case of internal combustion engine and centrifugal pump, and amount of finish is few, and cost is low, compact structure, conveniently moving.
Description of drawings
Fig. 1 is the assembling schematic representation of the crankcase cover of internal combustion engine of the utility model;
Fig. 2 is the structural representation of the crankcase cover of internal combustion engine of the utility model.
Among the figure:
Crank case of internal combustion engine 10a internal combustion engine moving power output shaft 20a
End face 101 sides 102
Vent 15 bearings 20
Oil sealing 30 water seals 40
Embodiment
In order further to explain the technological scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Shown in Fig. 1 to 2, the crankcase cover of internal combustion engine of the utility model comprises body 10, bearing 20, oil sealing 30 and water seal 40.
The surface of body 10 is made up of with the side that is connected both ends of the surface 101 102 both ends of the surface 101; Body 10 is provided with the shoulder hole 11 that is used to wear the internal combustion engine moving power output shaft; Shoulder hole 11 comprises the coaxial bearing hole 12, oil sealing hole 13 and the water seal hole 14 that are connected successively; The aperture in bearing hole 12, oil sealing hole 13 and water seal hole 14 that is to say that by large and small and variation greatly successively the aperture at the two end part of shoulder hole 11 is big; The aperture in stage casing is smaller, can play comparatively desirable water seal and oil sealing effect like this; In addition, the aperture in bearing hole 12 and water seal hole 14 can be identical, also can be different.In bearing hole 12, oil sealing hole 13 and the water seal hole 14 respectively correspondence bearing 20, oil sealing 30 and water seal 40 are set, and the hole wall between oil sealing hole 13 and the water seal hole 14 is provided with the vent 15 that connects body 10 surfaces.
As a preferred embodiment of the utility model, vent 15 connects the side 102 of body 10.
During assembling; One end face 101 of body 10 is affixed with the casing of crank case of internal combustion engine 10a; The other end 101 of body 10 is affixed with the housing of centrifugal pump 30a, and internal combustion engine moving power output shaft 20a passes bearing 20, oil sealing 30 and water seal 40 backs successively and from shoulder hole 11, stretches out.Water that from centrifugal pump 30a, leaks and the machinery oil that from crank case of internal combustion engine 10a, leaks discharge through vent 15, and the water that flows through centrifugal pump 30a can be taken away the heat of crankcase cover of internal combustion engine, has reduced the operating temperature of internal-combustion engine.
After adopting said structure, the utility model has reduced by a lid, and the pump cover that is about to crankcase cover of internal combustion engine and centrifugal pump unites two into one; Can improve the efficiency of assembling of crank case of internal combustion engine 10a and centrifugal pump 30a; And amount of finish is few, and cost is low, compact structure, conveniently moving.
The product form and the style of the foregoing description and accompanying drawing and non-limiting the utility model, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
