Oil Field Pump Unit Hybrid Gear Reducer |
| 摘要 |
An oilfield pumping unit two-stage transmission gear reducer includes a low speed stage having a low speed shaft configured to receive motion from an intermediate shaft. A first gear pair includes a low speed shaft double circular arc gear mounted on the low speed shaft and configured to be driven by an intermediate shaft double circular arc gear mounted on the intermediate shaft. A high speed stage includes a high speed shaft configured to receive motion from an intermediate shaft. A second gear pair has a high speed shaft involute gear mounted on the high-speed shaft and configured to be driving an intermediate shaft involute gear mounted on the intermediate shaft. |
