Technical Field
The utility model relates to the technical field of engine idle gears, in particular to a low-vibration forced lubrication idle gear assembly.
Background
The idle gear is a gear which plays a role of transmission between two transmission gears which are not in contact with each other, is meshed with a driven wheel in the previous stage of transmission and a driving wheel in the next stage of transmission simultaneously, and is used for changing the rotation direction of the driven wheel to be the same as that of the driving wheel. The idle gear is a wheel which does not do work, has a certain energy storage function, and can also maintain the stability of the system. Idler gears are very commonly used in machinery, which facilitates coupling to a remote shaft. In the engine, the currently used idle gear also needs to consider the vibration coefficient, namely stability and running resistance of the installed idle gear, so as to improve the stability and reliability of the whole gear train and directly influence the output efficiency and reliability of the engine. Aiming at the defects that the smoothness is insufficient mainly based on the lubricating effect of the currently used idle gear assembly, the traditional idle gear assembly can not meet the requirements of low vibration, high smoothness, low resistance, effective lubrication and the like more and more along with the increasing complexity and the increasing external output power of the gear train of the current engine.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problems, the utility model provides the low-vibration forced lubrication idler gear assembly which has the advantages of stable operation, good lubrication effect, low oil consumption and good reliability.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a low-vibration forced lubrication idler gear assembly comprises an idler gear, an idler gear shaft seat and a rolling bearing; the idle gear shaft seat is provided with a main lubricating oil duct from the rear end along the central axial direction, and the idle gear shaft seat is also provided with an oil outlet duct along the radial direction; the inner end of the oil outlet channel is communicated with the lubricating main oil channel; the idle gear shaft seat is also sleeved with a pressure oil concave ring, the inner side of the pressure oil concave ring is provided with a circle of oil storage concave cavity which is correspondingly sleeved at the oil outlet duct, and the port of the oil outlet duct is covered in the range of the oil storage concave cavity; the top of the pressure oil concave ring is also provided with an oil injection small hole; the front side and the rear side of the pressure oil concave ring are respectively distributed with one rolling bearing; the idler gear is tightly sleeved on the outer rings of the two rolling bearings.
Furthermore, two elastic clamping rings are correspondingly distributed outside the pressure oil concave ring.
Furthermore, a plurality of fixing holes are axially formed in the idle gear shaft seat and are tightened to the flywheel shell through fixing bolts.
Furthermore, the rear end of the lubricating main oil duct is provided with an oil duct connector for connecting a lubricating oil pipeline; the oil way connector is radially provided with an oil inlet which is communicated with the lubricating main oil duct.
Furthermore, the diameter of the small oil injection hole is 0.6-0.9 mm.
Further, the diameter of the oil injection small hole is 0.8 mm.
Compared with the prior art, the utility model has the beneficial effects that:
(1) by adopting the utility model, the lubricating main oil duct, the oil outlet duct and the oil pressing concave ring are arranged, so that the idler gear component is forcibly lubricated in a high-pressure lubricating mode; the pressure oil concave ring that is equipped with has at the use and accomodates, store lubricating oil, play adjustment buffer oil pressure, effect such as control lubricating oil supply, can both continuously maintain better lubricating property guaranteeing idle gear long-term rotation process, and simultaneously, the oil consumption has been saved to the maximize, effectively ensure the low resistance and the smoothness nature of operation, improve the transmission efficiency of engine gear train, still combine to be equipped with the double rolling bearing mode simultaneously, on promoting above-mentioned lubricating effect basis, can also show the stationarity that improves idle gear transmission operation, low vibration and reliability, compare general structure and can bear bigger transmission torque and keep stationarity and the reliability that should.
(2) Under the combination of the structure, the diameter of the oil injection hole of the oil pressing concave ring is preferably 0.8mm, so that the best lubrication effect can be realized, the diameter of the oil injection hole which is more than 1.5mm and is commonly used in the industry is directly adopted, after the oil injection hole is tested and operated for a period of time in different environments, the phenomenon that parts moving forward and backward randomly and respectively burn out occurs for many times, the result is the same through replacing parts with higher strength, and the fundamental reason is that although the oil quantity is large enough by adopting the conventional diameter of 1.5mm, the lubricating oil film cannot be effectively formed in the moving parts on the front side and the back side under the structure, and further the expected lubrication effect cannot be realized (possibly based on the influence of the structure such as the oil pressing concave ring, the elastic clamping ring and the like). And through reducing the nozzle opening diameter, impel the nozzle opening blowout lubricating oil then lubricating oil can effectively realize effective lubrication along the effective reposition of redundant personnel of both sides around, ensure the high-speed lasting operation of moving part.
