Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of water pump, and more particularly a kind of motor car engine is used cooling waterpump.
Background technique
Engine cooling water pump is a vitals in the engine-cooling system, and cooling waterpump pressurizes to cooling liquid, guarantees that cooling liquid circulates the heat that produces when taking away engine operation in cooling system, keep the motor normal working temperature.Existing engine cooling water pump directly is connected water pump through links such as bolts usually with engine cylinder; Pad is established sealing gasket between cooling waterpump and cylinder body; And position installation through bolt, and the positioning hole on the sealing gasket is often greater than the diameter of screw, the accurate location difficulty of sealing gasket; Cause the assembly crewman in assembling water pump difficulty on the one hand, sealing gasket is installed the insecure shortcoming of sealing that is prone to cause not in place on the other hand.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of assembling simple, assembling back reliable sealing engine for automobile cooling waterpump.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of motor car engine is used cooling waterpump; Include the water pump cover that is connected with the engine cylinder housing and be arranged in the shaft connecting bearing on the water pump cover; Be pressed into water seal between said shaft connecting bearing and the water pump cover, said shaft connecting bearing is provided with impeller near an end of water seal, and the other end is provided with belt pulley; It is characterized in that: the end face that described water pump cover and engine cylinder housing fit is provided with annular groove, in the said annular groove rubber seal is housed.
Through adopting technique scheme, the connection end face of water pump cover is provided with annular groove, is embedded with rubber seal in the groove; Rubber seal is through the annular groove location; Rubber seal is installed simple, and accurate positioning is reliable, and the water pump assembling is more simple; And rubber seal assembling back rubber seal is difficult for displacement, has better sealing; Through links such as bolts water pump cover is connected with engine cylinder body then, the water pump assembling is simple, and good seal performance; Avoid the sealing gasket assembling a series of problems that cause not in place simultaneously.
The utility model further is set to: described belt pulley includes the belt wheel body and the confession belt pulley that supply belt to connect and is installed in the assembly department on the shaft connecting bearing; Described belt wheel body is a tubular structure; Said belt wheel body shaft is to being outward extended with joint with respect to the other end towards impeller one end, and the end that joint extends is gathered and is connected with assembly department to axis.
Through adopting technique scheme, belt pulley covers shaft connecting bearing and water pump cover joint, makes water pump structure compact more on the one hand; Can prevent that on the other hand dust from falling into shaft connecting bearing and water pump cover joint.
The utility model further is set to: described water pump cover is provided with stiffening rib with respect to pasting two mutually with engine cylinder body, and said stiffening rib is a triangle.
Through adopting technique scheme, further increased the intensity of water pump cover.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the stereogram of the specific embodiment of the utility model;
Fig. 2 is the half sectional view of the specific embodiment of the utility model;
Fig. 3 is the belt sheave structure schematic representation of the utility model.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the disclosed a kind of motor car engine of the utility model is used cooling waterpump, includes water pump cover 1 and shaft connecting bearing 2, and shaft connecting bearing 2 passes water pump cover 1, has been pressed into water seal 4 between said shaft connecting bearing 2 and the water pump cover 1; Said shaft connecting bearing 2 is provided with impeller 5 near an end of water seal 4, and the other end is arranged with belt pulley 3; Described belt pulley 3 includes the belt wheel body 31 and the confession belt pulley 3 that supply belt to connect and is installed in the assembly department 32 on the shaft connecting bearing 2; Described belt wheel body 31 is a tubular structure; Described water pump cover 1 is provided with attachment hole 14; Described water pump cover 1 is provided with annular groove 13 with the end face that engine cylinder body fits, and is embedded with the rubber seal 130 that water pump cover 1 and engine cylinder housing is formed reliable sealing in the said annular groove 13; Insert in the attachment hole 14 through links such as bolts earlier, water pump cover 1 is fixedly connected with engine cylinder body, form the sealing of water pump cover 1 and engine cylinder body through rubber seal 130; Rubber seal 130 positions installation through annular groove 13, and rubber seal 130 is installed simple and reliable, can in the water pump assembly process, not be shifted simultaneously, and the water pump assembling is simple, better tightness between assembling back water pump and the engine cylinder housing.Certainly as the feasible technological scheme of the utility model, all right filling sealer in the annular groove on the described water pump cover 1, but sealer exists the hot after-tack of chance to seal insecure problem, so the utility model preferentially adopts the rubber seal setting.
For further making water pump cover 1 reliable installation, described water pump cover 1 is with respect to being provided with stiffening rib 11 with opposite side that engine cylinder body pastes a side mutually, and said water pump cover both sides are provided with stiffening rib 11, and said stiffening rib 11 is a triangle; The intensity rubber of having strengthened water pump cover 1 is set like this, makes water pump cover 1 reliable installation.
For effectively avoiding water seal 4 when damaging; Water is unlikely to flow to the damage that causes shaft connecting bearing 2 on the shaft connecting bearing 2; Described water pump cover 1 is provided with on the side of stiffening rib 11 and also is provided with spilled water hole 12, and described spilled water hole 12 is in communication with the outside water pump cover 1 inside.
The foregoing description only is used to explain the usefulness of the utility model; It is not restriction to the utility model; Those skilled in the art are under the connotation of the utility model instructs; Also corresponding distortion and modification can be made, shapes such as rectangle can be like the shape of stiffening rib, so all technological schemes that are equal to all fall into the protection category of the utility model.
