Abstract
The utility model discloses a main decelerator assembly used for the loading machine oscillating driving axle and pertains to the engineering machinery, wherein the main decelerator assembly has a casing of the main decelerator; the casing of the main decelerator is an integral structure; the casing of the main decelerator is connected with the main transmission gear pair, a cover unit and a bearing base; the main transmission gear pair of the main decelerator are the double-surface curve gear pair and the outside of the casing of the main decelerator is connected with a supporting sleeve. The decelerator has the advantages that the main transmission gear pair of the main the decelerator assembly adopts the powerful curve the gear pair, thereby improving the ability of the main decelerator to undertake the torque. Under the circumstance of the same axle load and the same general speed ratio, the device greatly improves reliability of the main decelerator. The loading capacity is strong, the structure is simple and reliable, the technology is high and the device is easy to dissemble or maintenance. The four oil tanks of the bearing enable the lubricant for the main decelerator that is contained in the internal axle cavity to effectively cycle for stabilizing the oil pressure, thereby making the transmission more stable and the sealing more reliable. The bearing has a good lubrication effect, thereby improving the service life of the main decelerator.
Description
Technical field
The utility model relates to a kind of main gearbox assembly of engineering machinery, particularly a kind of loader wobble drive bridge main gearbox assembly.
Background technique
At present, the main gearbox assembly that uses on the ransaxle of engineering machinery mainly comprises main subtract housing, main drive gear pair, bearing support, cap assemblies and adpting flange, the main drive gear of main drive gear pair is the active helical bevel gear, the employing supporting form that bridges, main subtracting is connected with main drive gear pair, bearing support, adpting flange etc. in the housing, it is split-type structural that the master subtracts housing, is formed by connecting by upper and lower casing, and main subtracting has the bridge of circle bag on the housing; This main gearbox assembly bearing capacity and transmission performance are poor, and the lubrication effect of bearing is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing capacity and transmission performance strong, the loader wobble drive bridge main gearbox assembly of the high lubricating effect of bearing.
The purpose of this utility model is achieved in that this main gearbox assembly has the main housing that subtracts, it is monolithic construction that the master subtracts housing, be connected with main drive gear pair, cap assemblies and bearing support in the housing main subtracting, the main drive gear pair of main reducing gear is the hyperboloid tooth wheel set, subtracts housing the master and is externally connected with supporting sleeve.
One oil duct that is communicated with is arranged on the described bearing support, also have 4 uniform oil grooves, the filler opening of bearing support oil duct communicates with leading the corresponding oil channel hole that subtracts on the housing, and with bridge bag intracavity inter-connection, the oil outlet of bearing support oil duct is communicated with bearing.
The axis of described main drive gear pair links to each other with preceding swing frame, and base ratio is 4.875.
Beneficial effect: owing to adopt such scheme, because the main drive gear pair of main gearbox assembly has adopted the hyperboloid tooth wheel set, the surface of contact of hyperboloid tooth wheel set is bigger, and the bearing torque ability is stronger, and transmission performance is better; The master subtracts housing and main reducing gear connects as one, and makes the master subtract axle housing and has enough rigidity and bearing capacity; 4 oil grooves of bearing support play trapped fuel and oil return effect, make the lubricant oil that bridge bag inner chamber contains main reducing gear can obtain circulation effectively, steadily oil pressure, make that finally transmission is more steady, seal more reliably, in the working life of having improved main reducing gear, reached the purpose of this utility model.Advantage is: the main drive gear pair of main gearbox assembly has adopted the more intense hyperboloid tooth wheel set of ability, improved the main ability of bearing moment of torsion that subtracts, under the situation of identical axle load and identical overall ratio, improved the reliability of main reducing gear greatly, bearing capacity is strong, simple and reliable, good manufacturability, be convenient to the dismounting maintenance, 4 oil grooves of bearing support make the lubricant oil that bridge bag inner chamber contains main reducing gear can obtain circulation effectively, steadily oil pressure, make that finally transmission is more steady, seal more reliable, the high lubricating effect of bearing, the working life of having improved main reducing gear.
