Description
Technical field
The utility model relates to the pressure lubrication oil circuit in a kind of pressure lubrication oil circuit, the especially epicyclic gearbox of gear-box.
Background technique
At present, mostly the lubricating system that contains planetary gear-box is with splash lubrication to be main, and this is because planet carrier all is a revolving part, can't take over the road as the parallel-axes gears case and carry out pressure lubrication.Though splash lubrication structure is simple; Pipeline connects convenient, but there are many shortcomings in this kind lubricating system, at first owing to have a large amount of lubricant oil in the splash lubrication requirement gear-box;, planet carrier will inevitably stir oil when rotating; Thereby produce a part of power loss, secondly splash lubrication can not make the inner heat of gear-box take away rapidly, and splash lubrication can not clean out the inner impurity of gear-box timely in addition.How to avoid these shortcomings of splash lubrication, and make epicyclic gearbox that good use efficient can be arranged, become the problem that people pay close attention to.
The model utility content
The purpose of the utility model is: existing contain exist on the planetary gear-box lubricating system gear-box in need deposit a large amount of lubricant oil; The in-fighting of work middle gear case is big; And internal heat can't be taken away rapidly; The inner impurity of gear-box is difficult to the practical problem of cleaning in time, and the pressure lubrication oil circuit in a kind of new epicyclic gearbox is provided.
The purpose of the utility model is achieved in that the pressure lubrication oil circuit in a kind of epicyclic gearbox; At least comprise one group of planetary gear train in the epicyclic gearbox, the inlet of pressure lubrication oil circuit is located on the casing, it is characterized in that: every group of planetary gear train is provided with independently pressure lubrication oil circuit; At each independently in the pressure lubrication oil circuit; Be equipped with interior lubricating oil path in planet carrier bearing support and the planet carrier, be provided with metal oil conduit between the lubricating oil path in the inlet of pressure lubrication oil circuit and the planet carrier bearing support, dock through the oil sealing piece between the interior lubricating oil path of planet carrier bearing support and the interior lubricating oil path of planet carrier; Interior lubricating oil path in the planet carrier sprays oil circuit by planet wheel bearing lubricating oil path and sun gear mesh tooth face and forms; Wherein, the terminal point of planet wheel bearing lubricating oil path is positioned at each planet wheel shaft, for planet wheel bearing provides lubricated; The sun gear mesh tooth face sprays terminal point each contiguous block between the disc of the front and back of planet carrier of oil circuit, and contiguous block is provided with the jet that points to the sun gear mesh tooth face.
In the utility model: independently in the pressure lubrication oil circuit, be provided with three jets that point to the sun gear mesh tooth faces between the front and back disc of said planet carrier on each contiguous block at least at each.
In the utility model: be provided with pipe joint on the inlet of the pressure lubrication oil circuit of casing.
The advantage of the utility model is: because oil leab is arranged on planet carrier inside; Lubricant oil can directly arrive at the bearing of planet wheel; Be ejected into the sun-planet wheel Surface of action through jet simultaneously; Bearing and the sun-planet wheel Surface of action to planet wheel adopt pressure lubrication simultaneously, guarantee lubricated more reliable; Because the lubricant oil of pressure lubrication system is to adopt the outer circulation mode to get into casing by the inlet of pressure lubrication oil circuit, as long as in the circulating oil path filter cleaner is set outside, the impurity in just can lubricant removal prolongs replacement cycle of lubricant oil, improves lubricating quality; After lubricant oil adopts outer circulation, significantly reduce the trapped fuel amount in the gear-box, reduced the power consumption in the planet carrier motion, improved the efficient of gear-box.
