Detailed Description
The invention will be further described and illustrated with reference to the accompanying drawings.
Two oil blanket II 9 divide into the three-section with transaxle middle section inner chamber lubricating oil, and tip cavity I17 is full of oil, and the oil level line 16 in middle cavity 18 and the tip cavity II 19 is as shown in fig. 5, and when the leveler got into the operation on the slope by the horizontal operating mode, the lubricating oil in tip cavity I17 or the tip cavity II 19 that is in the high-order can partly flow into middle cavity 18, and final oil level still can satisfy bearing I7 lubrication.
The oil collecting groove 12 designed on the secondary speed reducing shell 1 collects splashed lubricating oil, and the collected lubricating oil can flow into the end cavity I17 or the end cavity II 19 of the high-level end through the oil passage part, so that the oil quantity of the end cavity I17 or the end cavity II 19 of the high-level end is ensured. When the grader returns to the horizontal working condition for operation, the end cavity I17 or the end cavity II 19 can gradually restore to the full oil state through oil collection.
When the land leveler works on a slope, the lubricating oil collected by the oil collecting tank 12 on the secondary speed reducing shell 1 flows onto the bearing II 10 of the intermediate cavity 18 through the oil duct to perform shower lubrication on the bearing II 10.
The Z-shaped oil duct 13 or the obliquely penetrating oil duct I14 or the obliquely penetrating oil duct II 15 is adopted by the oil ducts of the connecting holes of the end part cavity I17, the end part cavity II 19 and the middle cavity 18, so that oil splashed in the end part cavity I17 and the end part cavity II 19 is prevented from flowing into the middle cavity 18 through the oil ducts, the oil level of the end part cavity I17 and the oil level of the end part cavity II 19 are reduced, and the land leveler can work on a slope for a long time.
An oil level indicator 2 is installed on the secondary speed reduction shell 1, the oil level indicated by the oil level indicator 2 is the minimum oil level required by lubrication of the bearing I7, and when the land leveler works on a slope, lubricating oil is observed through the oil level indicator 2. The position of the structural design shows that the land leveler is in a full oil state when operating on a horizontal working condition or a slope.
