Embodiment Construction

[0008] like figure 1 , 2 As shown, the cylindrical casing 20 of the lubricating pump is fixedly connected with the drive shaft 10, the inner side of the casing 20 is provided with an outer rotor 30 fixedly connected with it, and the inner side of the outer rotor 30 is provided with a cycloidal gear meshing with it. The inner rotor 40 of the inner and outer rotors 40, 30 is provided with a sealing cover plate 50 between the end faces of the inner and outer rotors 40, 30 away from the drive shaft 10 and the installation reference surface 80 of the lubricating pump. The plate 50 is provided with an eccentric hole and an inlet 51 and an outlet 52 for the circulation of lubricating oil. The rotating shaft 70 passes through the inner rotor 40 and the eccentric hole in turn and abuts against the installation reference surface 80. The drive shaft 10 drives When the housing 20 rotates, lubricating oil is sucked from the inlet 51 on the sealing cover 50 , and is discharged from the out...

Abstract

The invention belongs to lubrication technical field, concretely relates to a lubricating pump. The lubricating pump includes an internal rotor and an external rotor which are in cycloid type gear engage engagement with each other, gears of the internal rotor and the external rotor are engaged with each other for sucking and supplying oil. The lubricating pump of the present invention adopts a machine-pump integrated structure, has characteristics of built-in integration and without outer leakage, heat generated when the lubricating pump is working is brought by the lubricating fluid, so thatstable and safe operation of whole system is guaranteed, the present invention reduces middle transmission link, realizes synchronous operation of the lubricating pump and lubricated mechanism or device, not only increases working efficiency of the lubricating pump, but also increases work life of the lubricating pump.

Description

technical field [0001] The invention belongs to the technical field of power lubrication, and in particular relates to a lubrication pump. Background technique [0002] In order to ensure the continuous and stable operation of the mechanism in the mechanical system, it is necessary to fully and effectively lubricate the parts that cooperate with each other in the mechanism, so a lubrication oil supply device needs to be installed in the system. An oil pump for an internal combustion engine (GB2100354A) discloses that the outer casing of the oil pump is fixedly connected to the drive shaft, the inner side of the outer casing is provided with an outer rotor fixedly connected with it, and the inner side of the outer rotor is provided with a cycloidal gear meshing with it. The inner rotor of the inner and outer rotors is provided with a sealing cover plate on the end face far away from the drive shaft, and the sealing cover plate and the outer shell are set to rotate and coopera...
