Abstract
The invention relates to a speed reducer used for a submersible progressing cavity pump. According to the technical scheme, the speed reducer comprises two stages of planet gear speed reduction devices. A first-stage speed reduction sun gear, a first-stage speed reduction planet gear, a first-stage speed reduction fixed gear and a first-stage speed reduction planet gear support are connected to form the first-stage speed reduction device. A second-stage speed reduction sun gear, a second-stage speed reduction planet gear, a second-stage speed reduction fixed gear and an output shaft and planet gear support are connected to form the second-stage speed reduction device. The two stages of speed reduction devices are connected together through an intermediate connection body and a reducing spline sleeve and form the speed reducer, with the speed reduction ratio of 12.25, together with a base, a head part and an alignment bearing. The speed reducer has the beneficial effects that the compatibility with the submersible progressing cavity pump and other parts is high, and most accessories are universal; the structure is simple, and the speed reducer is easy to manufacture, install and maintain; and due to the new transmission ratio, the speed reducer can be used for more units.
