The purpose of this utility model completes by following technical solution, the inside oil charging structure of described gear-box, it is mainly by oil-feed bearing support, oil-feed sliding bearing, rolling bearing, oil sealing, oil sealing base, oil-feed cover, interior endless tube, outer endless tube, fixedly oil-feed cover, input shaft, rotation planet carrier form; Described oil-feed sliding bearing, rolling bearing, oil sealing and oil sealing base are fixed on oil-feed bearing support, and form an oil-feed assembly, and this oil-feed assembly is fixed on rear cabinet; Described oil-feed cover, interior endless tube, outer endless tube and fixedly oil-feed cover form the logical oily assembly in an inside, and one end of the logical oily assembly in this inside is supported on the bearing of oil-feed assembly, and one end is fixed on the input shaft of rotation; Described fixedly oil-feed cover and rotation planet carrier are separately fixed on input shaft, they are radially having radially oil inlet hole respectively, and form the oily assembly of part in, and the oil content passing into is assigned to planet wheel, each lubricating point of planetary bearing, this interior part oil assembly is supported on front casing by bearing.
In described oil-feed bearing support periphery, have several for from outside through the oil inlet hole of this oil-feed; Oil-feed sliding bearing is fixed on the endoporus of oil-feed bearing support, uniform several oilholes that has on its circumference; Described oil-feed cover is placed in the endoporus of oil-feed bearing support by described sliding bearing and rolling bearing; Described oil sealing is assemblied in oil sealing base.
The utility model both provided a kind of layout that can reduce pipe joint, avoided oil seepage; Can subtract the centrifugal force of primary oil flow again, improve lubrication effect; And realize the each point sufficient lubrication on gear-box inner rotation planet carrier, be convenient to again processing and assembling; Save the object of later maintenance simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the inside oil charging structure of gear-box described in the utility model, it is mainly by oil-feed bearing support 14, oil-feed sliding bearing 11, rolling bearing 15, oil sealing 17, oil sealing base 16, oil-feed cover 10, interior endless tube 8, outer endless tube 7, fixedly oil-feed cover 5, input shaft 4, rotation planet carrier 3, bearing 2 and casing 1 form; Described oil-feed sliding bearing 11, rolling bearing 15, oil sealing 17 and oil sealing base 16 are fixed on oil-feed bearing support 14, and form an oil-feed assembly, and this oil-feed assembly is fixed on rear cabinet; Described oil-feed cover 10, interior endless tube 8, outer endless tube 7 and fixedly oil-feed cover 5 form the logical oily assemblies in inside, and one end of the logical oily assembly in this inside is supported on the bearing of oil-feed assembly, and one end is fixed on the input shaft 4 of rotation; Described fixedly oil-feed cover 5 and rotation planet carrier 3 are separately fixed on input shaft 4, they are radially having radially oil inlet hole 6 respectively, and form the oily assembly of part in, and the oil content passing into is assigned to planet wheel, each lubricating point of planetary bearing, this interior part oil assembly is supported on casing 1 by bearing 2.
In described oil-feed bearing support 14 peripheries, have several for from outside through the oil inlet hole 13 of this oil-feed; Oil-feed sliding bearing 11 is fixed on the endoporus of oil-feed bearing support 14, uniform several oilholes 12 that has on its circumference; Described oil-feed cover 10 is placed in the endoporus of oil-feed bearing support 14 by described sliding bearing 11 and rolling bearing 15; Described oil sealing 17 is assemblied in oil sealing base 16.
Embodiment: shown in Fig. 1, the utility model is mainly by oil-feed bearing support 14, oil-feed sliding bearing 11, rolling bearing 15, oil sealing base 16, oil sealing 17, oil-feed cover 10, interior endless tube 8, outer endless tube 7, fixedly oil-feed cover 5, input shaft 4, rotation planet carrier 3, bearing 2, casing 1 etc. form; First, oil-feed sliding bearing 11, rolling bearing 15, oil sealing 17 and oil sealing base 16 are assemblied on oil-feed bearing support 14, form an oil-feed assembly, and its assembly is fixed on rear cabinet; In oil-feed bearing support 14 peripheries, have several oil inlet holes 13, for from outside through this oil-feed; Oil-feed sliding bearing 11 is fixed on 14 endoporus, and on it, circumference uniform distribution has several oilholes 12, and its effect is to guarantee to have in relative rotation in situation with oil-feed cover 10, and oil is delivered in oil-feed cover 10 and logical oily assembly; Rolling bearing 15, for supporting the rotation of oil-feed cover 10 and logical oily assembly, guarantees the stable of rotation; Oil sealing 17 is assemblied in oil sealing base 16, for sealed rotational assembly, prevents leakage of oil.
Secondly, oil-feed cover 10, interior endless tube 8, outer endless tube 7 and fixedly oil-feed cover 5 form the logical oily assemblies in inside, and form a logical oil pocket 9, the oil entering from oil-feed assembly is sent to inner each lubricating point of gear-box through logical oil pocket 9, its assembly one end is supported on the bearing of oil-feed assembly, and one end is fixed on the input shaft of rotation; Because it is positioned on the rotation center line of gear-box, when in gear-box, each parts rotate, lubricating oil flow track disperses to the periphery away from center line everywhere near gear-box center line, centrifugal action when this kind of design both can reduce lubricating oil flow, can accelerate the flowing velocity of lubricant oil again, and then strengthen inner each point lubrication effect; The many places pipeline that has simultaneously reduced traditional type casing peripheral disposition, reaches and avoids risk of leakage, saves later maintenance time and cost.
Have again, fixedly oil-feed cover 5 is fixed on input shaft 4, rotating planet carrier 3 is also fixed on input shaft 4, like this, inner logical oily assembly can rotate with input shaft 4, three changes direction through this radially having radially oil inlet hole 6, lubricant oil, from axially changing into radially, so just realized the oil inside offering object of the planet carrier 3 to rotating, and the oil content passing into is assigned to the lubricating points such as planet wheel, planetary bearing, gear ring, sun gear, its form one in the oily assembly of part, by bearing 2, be supported on front casing 1, realize rotating effect.Finally, said modules has formed the inner oil charging structure of complete gear-box, realizes each lubricating point fuel feeding of the inside of gear-box.
