The existing vacuum pump is mainly driven by a motor as a power source, and the motor, a belt pulley transmission mode and the like are utilized to drive rotors in the pump body of the vacuum pump to rotate, two rotors are usually arranged in the pump body, one of the two rotors is driven by the motor and the belt transmission mechanism, the other one is driven by the driving rotor through a gear box as a driven rotor, and the rotation of the two rotors enables the space in the pump body to be alternately changed so as to send air from an air inlet to an air outlet of the pump body to be discharged, so that the air-extracted space connected with the air inlet reaches the required vacuum degree. Obviously, above-mentioned structural style and transmission mode, motor and pump body are split type, need very accurate counterpoint in the time of the equipment just can hold the concentricity of equipment, and the degree of difficulty is great, and product machining precision is not enough to lead to whole equipment life weak point easily.
The utility model comprises the following steps:
the utility model aims to overcome the defects in the prior art and provide a direct-connection transmission type vacuum pump with an integrated end cover.
The technical scheme adopted by the utility model is as follows: the utility model provides a direct-connection transmission type vacuum pump with integral type end cover, includes drive assembly and pump body subassembly, and drive assembly includes motor housing and electronic rotor, and pump body subassembly includes pump body housing and two pump rotors, and it still includes an integral type end cover shared by drive assembly and pump body subassembly, integral type end cover includes an end cover main part that takes the form of cuboid, and the one side of this end cover main part outwards extends and forms the first flange terminal surface with the motor housing butt joint of drive assembly, and the opposite side then outwards extends and forms the second flange terminal surface with the pump body housing butt joint of pump body subassembly; two driving shaft holes and driven shaft holes for installing the pump rotor shaft are formed in the end cover main body, bearing installation parts are respectively arranged on the end cover main body, corresponding bearings are arranged on the end cover main body, and concave surfaces for installing an oil seal cover and an oil seal ring are respectively formed on the outer sides of the two bearing installation parts of the end cover main body; the rotating shafts of the driving rotors in the two pump rotors penetrate through the driving shaft holes and are directly connected with the electronic rotor of the driving assembly.
And sealing ring grooves and sealing rings are respectively formed on the inner walls of the end cover main body, which lean against the end face side of the second flange, the driving shaft hole and the driven shaft hole.
And oil holes are formed in the end cover main body and the side wall of the bearing installation part, and an oil supply pipe is connected with the end cover main body.
The driving component and the pump body component of the direct-connection transmission type vacuum pump adopt the shared integrated end cover, so that the die cost and the complicated assembly step for respectively forming the end covers can be saved, the step of difficulty in concentricity is avoided, the assembly accuracy and the assembly efficiency are improved, and the service life of equipment is prolonged.
