Embodiment Construction

[0017] The specific embodiment of the present invention takes the triangular rotor pump as an example, as shown in the accompanying drawings: its structure is made up of pump body 8, suction and oil discharge device, inlet and outlet ports 26,27. There is an oil inlet 26 and an oil outlet 27 communicating with the body outside the body of the pump body 8; the suction and oil discharge device located in the pump body 8 is composed of a triangular rotor 25 and a planetary epicyclic gear train; the planetary epicyclic gear train is mounted on The body of the triangular rotor 25, and both ends of the rotor shaft 1 in the triangular rotor 25 are connected to the pump body 8 through sealing. The front end of the rotor shaft 1 is installed on the front cover 5 of the pump body 8 through the front bearing 3 , the bearing seal 2 and the front gland 4 fitted thereon. The rear end of the rotor shaft 1 is installed on the rear cover 10 of the pump body 8 through the rear bearing 13 and th...

Abstract

The invention relates to a planetary cyclic gear train polygonal rotor pump, which belongs to a novel hydraulic pump used for absorbing and draining oil in the industrial field, and has the structure that the pump consists of a pump body, an oil absorbing and draining device, an oil inlet and an oil outlet, wherein, the oil absorbing and draining device is positioned inside the pump body; the outside of the pump body is provided with the oil inlet and the oil outlet communicating with the inside of the pump body; the oil absorbing and draining device consists of a polygonal rotor and a planetary cyclic gear train; a primer motor drives a rotor shaft to rotate and the planetary cyclic gear train drives the polygonal rotor to rotate at a high speed for realizing oil absorption and drainage. The novel planetary cyclic gear train polygonal rotor pump has the advantages of small volume, high pressure, large diskharge capacity, low noise, high rotary speed, long service life, etc., which can be used as a special pump requiring high-speed rotation in industry.

Description

technical field [0001] The planetary epicyclic train type polygonal rotor pump of the present invention belongs to a new type of hydraulic pump used for oil suction and discharge in the industrial field. Background technique [0002] At present, gear pumps, vane pumps, plunger pumps, diaphragm pumps, etc. are commonly used in the industrial field. The various pumps mentioned above have different advantages and are used in different fields, but they all have a common feature, that is, they are large in size and small in displacement, and the axis or axis of the power mechanism that presses the liquid is mostly fixed. For example, the vane of the vane pump rotates around its axis; the plunger of the plunger pump moves up and down along its axis. But above-mentioned various pumps all can't meet the requirement of high-speed operation, especially the high-speed rotation driven by AC servo motor, frequency conversion motor etc. Therefore, it is necessary to develop a planetary ...
