Abstract
An eccentric wear prevention device for a planetary gear of a decelerator aims to overcome the deficiency of short service life of the decelerator caused by the fact that the eccentric wear prevention device of the prior decelerator of an electric submersible rotary screw pump fails to effectively prevent the eccentric wear phenomenon of the gear of the decelerator. The eccentric wear prevention device comprises a planet carrier (1), a planet gear (5), a planet wheel axle (6) and a sun gear (7), wherein a roller pin (3) is mounted between an inner hole of the planet gear (5) and the excircle radial direction of the planet wheel axle (6), and the axes of the roller pin (3) parallels to that of the planet wheel axle (6); and an axial thrust bearing (2) is axially mounted between the planet gear (5) and the planet carrier (1). The eccentric wear prevention device has the benefits of reasonable structure and smooth transmission, thereby avoiding eccentric wear between the planet gear of the decelerator and the shaft, and effectively prolonging the service life of the decelerator.
Description
Affiliated technical field
The utility model relates to a kind of electric oil submerged screw pump retarder of petroleum production, especially relates to the anti-eccentric wear device of a kind of retarder planetary pinion.
Background technique
Electric oil submerged screw pump is applied to field of petroleum exploitation, and retarder is the critical component of electric oil submerged screw pump.Because electric oil submerged screw pump is positioned at the down-hole, its design space is subjected to the borehole size restriction, under the condition that can not improve the reducer gear modulus and the number of teeth, in order to improve the strength of gear teeth, need improve gear tooth width as much as possible, the increase of the facewidth, make the Dynamic factor of gear be a greater impact, add the error of retarder processing and assembling, cause between gear driven load inhomogeneous, unstable, cause retarder to damage easily.In order to improve the working life of retarder, prior art is installed sliding bearing at planet wheel and axle, and sliding bearing can not effectively prevent the generation of reducer gear eccentric wear phenomenon in actual use, causes the working life of retarder low, has a strong impact on normally carrying out of recovering the oil and produce.
The model utility content
Can not effectively prevent the generation of reducer gear eccentric wear phenomenon for the anti-eccentric wear device that overcomes existing electric oil submerged screw pump retarder, cause the working life of retarder low, have a strong impact on the deficiency of normally carrying out of recovering the oil and producing, the utility model provides a kind of retarder planetary pinion to prevent the eccentric wear device.The anti-eccentric wear device of this retarder planetary pinion can effectively be eliminated the influence of reducer gear processing and the excessive planet wheel coaxality difference that causes of alignment error accumulative total, and it is even more, stable that gear load is distributed.
The technological scheme that its technical problem that solves the utility model adopts is: the anti-eccentric wear device of retarder planetary pinion comprises planet carrier, planet wheel, planet wheel shaft, sun gear, in the axial bore at planet carrier center sun gear is installed, sun gear is meshed with planet wheel, planet wheel shaft is installed on the planet carrier, the endoporus of planet wheel and planet wheel shaft outer circle diameter between needle roller is installed, the axis of needle roller and the parallel axes of planet wheel shaft; Be axially installed with axial thrust bearing between planet wheel two ends and the planet carrier.Needle roller is a biserial, is equipped with between the 2 row needle rollers to adjust cover.Axial thrust bearing is a needle bearing.Planet wheel shaft has axial oil-through hole and radial direction oil hole, and axially oil-through hole and radial direction oil hole communicate, and radial direction oil hole communicates with axial thrust bearing, adjustment cover respectively.
The beneficial effects of the utility model are that rational in infrastructure, stable drive prevents between retarder planet wheel and the axle eccentric wear to take place, and effectively prolongs the working life of retarder.
