[0002] In addition to the power output at the flywheel end, construction machinery diesel engines generally need to have other power outputs, such as the movement of the entire vehicle, the movement of the harvesting mechanism of the harvester, the mixing movement of the mixer truck, the digging work of the excavator, the lifting of the crane and mining vehicle, etc., which all require PTO to provide power. At present, the transmission mechanism of construction machinery is complex and diverse, and the operating environment and working conditions are also extremely harsh. The existing power transmission mechanism cannot serve the construction machinery market well.

[0003] At present, a Chinese patent with the existing patent publication number of "CN111042913A" discloses a power output device of an engineering machinery diesel engine and an assembly method thereof, which belongs to the technical field of engine power output devices, including a PTO chamber, a PTO cover, a PTO output shaft, an oil seal, an outer bushing, an inner bushing, a bearing one and a bearing two, the PTO chamber and the PTO cover are bolted and fastened, the inner wall of the PTO chamber is connected to the bearing one and the bearing two by interference fit, an inner bushing and an outer bushing are arranged between the bearing one and the bearing two, the outer wall of the outer bushing is fitted with the inner wall of the PTO chamber, the inner wall of the inner bushing is fitted with the outer wall of the PTO output shaft, the PTO chamber is rotatably connected with the bearing one and the bearing two and the PTO output shaft through the bearing one and the bearing two, and both sides of the inner bushing and the outer bushing are respectively in contact with the bearing one and the bearing two, the power output device of this design can be combined with a hydraulic pump for power output, solve the defect that the steering system is easily damaged, and has strong versatility.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] Unable to effectively lubricate high-speed rotating bearings: When the power output device rotates, the ball bearings inside the power output device will also rotate at high speed. Moreover, a large amount of heat energy will be generated along with the rotation of the ball bearings. If this heat energy cannot be taken away in time, it will cause deformation of the inner and outer rings of the bearings and the retaining frame. In mild cases, it will cause bearing noise problems. In severe cases, it will cause the bearing system to be scrapped due to ablation. For this reason, we propose a power output device with forced lubrication. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies in the prior art, the utility model provides a power output device with forced lubrication, which connects the power output device with an engine by adopting an oil pipe, and then transports the engine oil inside the engine to the power output device through the oil pipe, thereby forcibly lubricating the power output device, thereby solving the technical problem that the existing power output device cannot effectively lubricate the bearings in a high-speed rotating state when in use, thereby causing the power output device to be scrapped.

[0008] (II) Technical solution

[0028] The embodiment of the present application provides a power output device with forced lubrication, which effectively solves the technical problem that the existing power output device cannot effectively lubricate the bearings in a high-speed rotating state when in use, thereby causing the power output device to be scrapped. When the power output device is in use, an oil pipeline is used to connect the power output device to the engine, and the oil pipeline then transports the engine oil inside the engine to the power output device, thereby forcibly lubricating the power output device, thereby achieving forced lubrication of the power output device, thereby ensuring the stability of the bearings in long-term operation, and also playing a role in cleaning the bearings.

[0029] Example

[0030] The technical solution in the embodiment of the present application effectively solves the technical problem that the existing power output device cannot effectively lubricate the bearings in a high-speed rotating state when in use, which causes the power output device to be scrapped. The overall idea is as follows:

[0031] In view of the problems existing in the prior art, the utility model provides a power output device with forced lubrication, the power output device comprises a PTO assembly mounted on an engine, such as Figure 4 As shown, the PTO assembly consists of a PTO chamber 11, a PTO gear 12, a transmission sleeve 13, a roller bearing 14 and an oil delivery pipe 15, wherein the PTO chamber 11 is mounted on the engine, and a transmission sleeve 13 and a PTO gear 12 are installed inside the PTO chamber 11. In order for the transmission sleeve 13 to be linked with the flywheel 2 of the engine, the PTO gear 12 at the rear end of the transmission sleeve 13 is meshed with the flywheel 2 of the engine (the two are not directly meshed, such as Figure 6 As shown, the two are linked by meshing with the same gear).

[0032] The PTO gear 12 is connected to the PTO chamber 11 through the roller bearing 14, so that when the PTO gear 12 rotates, the PTO chamber 11 can rotate relative to the PTO gear 12, so that the two can rotate relative to each other.

[0033] In order to lubricate the rotating PTO component, an oil pipe 15 capable of conveying engine oil is connected to the outside of the PTO chamber 11 (the oil pipe 15 is connected to the engine casing), so that the engine oil extracted from the engine can be conveyed to the PTO chamber 11 to lubricate the roller bearing 14 located inside the PTO chamber 11, and at the same time, impurities in the roller bearing 14 during use can be taken away.

[0034] The PTO gear 12 is connected to the rear end of the transmission sleeve 13, such as Figure 3 As shown, the transmission sleeve 13 is linked to the flywheel 2 of the engine through the PTO gear 12, and the housing 3 is mounted on the engine and the PTO assembly to wrap the PTO assembly and the engine, so that the engine oil extracted from the engine can be transported to between the PTO chamber 11 and the housing 3, and the engine oil flows in the housing 3, and then is re-delivered to the engine through the pipeline connected to the outside of the housing 3, thereby forming a circulation, through the oil pump (any device that can transport oil can be used, not limited to the oil pump).

[0035] During the specific implementation process, the engine oil inside the engine is transported to the PTO chamber 11 through the oil pipe 15, so that the engine oil flows inside the PTO chamber 11 and contacts the roller bearing 14 inside the PTO chamber 11, thereby taking away the heat and impurities generated by the roller bearing 14, and avoiding damage to the roller bearing 14 due to high temperature when rotating at high speed.

[0036] Forced lubrication effectively solves the problem of bearing failure caused by high temperature and lack of oil during high-power output of PTO, greatly improving the reliability of PTO.

[0037] For some PTOs with high power output, forced lubrication is necessary to ensure long-term operation of the bearings. Forced lubrication also has the function of cleaning the bearings.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
