[0001] The utility model relates to the field of planetary speed reducers, in particular to a self-lubricating system for the input end of a planetary speed reducer of a biomass cutting and tearing integrated machine. Background Technique
[0002] The planetary speed reducer is a widely used industrial product that can reduce the speed of the motor while increasing the output torque. The planetary speed reducer can be used as a supporting component in industries such as lifting, excavation, transportation, and construction. The planetary reducer has the characteristics of small volume, light weight, high load-bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency, and safe performance. It is a new type of reducer with wide versatility. Most of the currently used planetary speed reducers need to provide additional power for the lubrication system to maintain the operation of the lubrication system, which increases the occupied space of the planetary speed reducer and also increases the production and operation costs. Content of the Utility Model
[0003] The purpose of the utility model is to provide a self-lubricating system for the input end of a planetary speed reducer of a biomass cutting and tearing integrated machine to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A self-lubricating system for the input end of a planetary speed reducer of a biomass cutting and tearing integrated machine, including a reducer input shaft. An input end gear is sleeved and fixed on the outer side of the reducer input shaft, and an intermediate idler gear meshing with it is arranged on one side of the input end gear. A connecting gear meshing with the intermediate idler gear is arranged on one side of the intermediate idler gear, and the connecting gear is sleeved and fixed on the outer side of a connecting shaft. The connecting shaft is rotatably connected to the machine body, and a cycloidal oil pump is fixedly installed at the other end of the connecting shaft.
[0005] Preferably: The intermediate idler gear is sleeved and fixed on the outer side of an idler gear loose bearing, and the inner ring of the idler gear loose bearing is sleeved and fixed on the outer side of the installation column of the machine body.
[0006] Preferably: An input end filter is arranged on one side of the cycloidal oil pump.
[0007] Preferably: One end of the input end filter is communicated with one end of the cycloidal oil pump through an input end oil pipe.
[0008] Preferably: The other end of the cycloidal oil pump is communicated with an output end oil pipe, and the other end of the output end oil pipe points to the input end bearing of the speed reducer.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] The utility model drives the input end gear to rotate through the input shaft of the speed reducer. Thus, under the transmission and deceleration of the intermediate idler gear and the connecting gear, the cycloidal oil pump is driven to rotate. The lubricating oil enters the cycloidal oil pump through the input end filter and the input end oil pipe. During the rotation process, the lubricating oil at the other end of the cycloidal oil pump lubricates the bearing at the input end of the speed reducer through the output end oil pipe. This can be achieved without additional power drive and the oil supply only occurs when the speed reducer is working, which is more energy-efficient. Brief Description of the Drawings

A fixed input end gear 2 is sleeved outside the input shaft 1 of the speed reducer. And an intermediate idler gear 4 meshing with it is arranged on one side of the input end gear 2. A connecting gear 5 meshing with the intermediate idler gear 4 is arranged on one side of the intermediate idler gear 4. And the connecting gear 5 is sleeved and fixed outside the connecting shaft 7. The connecting shaft 7 is rotatably connected to the machine body. And a cycloidal oil pump 6 is fixedly installed at the other end of the connecting shaft 7.
[0017] In this embodiment, the intermediate idler gear 4 is sleeved and fixed outside the idler gear hollow bearing 3. And the inner ring of the idler gear hollow bearing 3 is sleeved and fixed outside the mounting column of the machine body. An input end filter 8 is arranged on one side of the cycloidal oil pump 6. One end of the input end filter 8 is communicated with one end of the cycloidal oil pump 6 through the input end oil pipe 9. The other end of the cycloidal oil pump 6 is communicated with an output end oil pipe 10. And the other end of the output end oil pipe 10 points to the bearing at the input end of the speed reducer.
[0018] Further, the input shaft 1 of the speed reducer drives the input-end gear 2 to rotate. Thus, under the transmission and speed reduction of the intermediate idler gear 4 and the connecting gear 5, the cycloidal oil pump 6 is driven to rotate. The lubricating oil enters the cycloidal oil pump 6 through the input-end filter 8 and the input-end oil pipe 9. During the rotation process, the lubricating oil at the other end of the cycloidal oil pump 6 lubricates the bearings at the input end of the speed reducer through the output-end oil pipe 10. This can be achieved without additional power drive, and oil supply only occurs when the speed reducer is working, which is more energy-efficient.
[0019] The working principle of the present utility model: The input shaft 1 of the speed reducer drives the input-end gear 2 to rotate. Thus, under the transmission and speed reduction of the intermediate idler gear 4 and the connecting gear 5, the cycloidal oil pump 6 is driven to rotate. The lubricating oil enters the cycloidal oil pump 6 through the input-end filter 8 and the input-end oil pipe 9. During the rotation process, the lubricating oil at the other end of the cycloidal oil pump 6 lubricates the bearings at the input end of the speed reducer through the output-end oil pipe 10.
