Abstract
The utility model discloses an improvement structure of automatically controlled gearbox idler shaft, include idler shaft, bearing, gear, a plurality of retaining ring, join in marriage food tray and rand, the gear cup joint on the idler shaft through the bearing, the both sides of bearing be equipped with respectively be used for the location the retaining ring. Join in marriage that the food tray is fixed to be cup jointed in the outer end of idler shaft and fixed through the rand, be equipped with lubricated oil duct in the idler shaft, join in marriage the food tray in the terminal surface offered a plurality of oil circuit recesses, the end that produces oil of this oil circuit recess links up with the bearing, the oil feed end of this oil circuit recess feeds through with the lubricated oil duct in the idler shaft. Because the utility model discloses a single bipyramid bearing supports, joins in marriage the food tray at axle head fixed, and lubricating oil spouts and lubricate to the bearing awl through joining in marriage the food tray oil duct from the right entry oil duct of idler shaft from the idler shaft left end, and the velocity of flow and the pressure of lubricating oil are controlled by the filling valve, avoid the velocity of flow lead to at the excessive speed lubricated not enough, cross slow and heat dissipation less than the defect, have compact structure, the effectual advantage of lubrication.
Description
Technical field
The utility model relates to engineering machinery field, particularly relates to a kind of modified node method of electrically controlled gearbox idler shaft.
Background technique
As shown in Figure 1, in traditional gearbox, idler shaft comprises idler shaft 1 ', two bearings 2 ', gear 3 ' and multiple back-up rings 4 '.Described gear 3 ' is socketed on idler shaft 1 ' by two bearings 2 ', is respectively equipped with the back-up ring 4 ' for locating in the both sides of bearing 2 '.In this conventional gearbox, the bearing lubrication mode of idler shaft 1 ' is generally by offering L shape oil duct 11 ' in idler shaft 1 ' inside, offer some oilholes in the radial direction of back-up ring 4 ' simultaneously, this L shape oil duct 11 ' and oilhole mutual conduction, lubricant oil lubricates bearing 2 ' through the L-type oil duct 11 ' of idler shaft 1 ' and the oilhole of back-up ring 4 ', adopt and lubricate in this way, lubricant oil often first covers the oilhole of back-up ring 4 ', flow into the cavity between back-up ring 4 ' and gear 3 ' and both sides bearing 2 ' simultaneously, cause the flow of lubrication flowing into both sides bearing 2 ' limited like this, cannot lubricate the bearing 2 ' of both sides fully, bearing 2 ' lubrication effect is poor.And idler shaft 1 ' adopts duplex bearing to support in this conventional gearbox, structure is comparatively complicated, and cost is higher.
Summary of the invention
The purpose of this utility model is the modified node method of the electrically controlled gearbox idler shaft providing a kind of compact structure, high lubricating effect.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of modified node method of electrically controlled gearbox idler shaft, comprises idler shaft, bearing, gear and multiple back-up ring; Described gear is connected on idler shaft by bearing housing, is respectively equipped with the back-up ring for locating in the both sides of bearing; Also comprise oil distribution casing and collar; The fixedly sleeved outer end at idler shaft of described oil distribution casing and being fixed by collar, oil leab is provided with in idler shaft, oil distribution casing interior edge face offers some oil circuit grooves, and the oil outlet end of this oil circuit groove is connected with bearing, and the oil inlet end of this oil circuit groove is communicated with the oil leab in idler shaft.
Oil circuit groove on described oil distribution casing is cross-type, to increase lubricating efficiency.
Oil leab in described idler shaft is made up of a vertical passage and two radial passages; The import of vertical passage is positioned at the inner of idler shaft, and the inlet communication of the outlet of vertical passage and two radial passages in criss-crossing, the outlet of radial passage is communicated with the oil inlet end of oil circuit groove.
After adopting such scheme, because the utility model adopts single bipyramid bearings, an oil distribution casing is fixed at axle head, lubricant oil enters oil duct from the right-hand member of idler shaft and sprays to bearing awl from idler shaft left end by oil distribution casing oil duct and lubricate, flow velocity and the pressure of lubricant oil are controlled by oiling valve, avoid flow velocity too fastly to cause lack of lubrication, cross slow and heat radiation is not enough defect, there is the advantage of compact structure, high lubricating effect.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation commonly using idler shaft in gearbox;
Fig. 2 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of modified node method of electrically controlled gearbox idler shaft, comprises idler shaft 1, bearing 2, gear 3, multiple back-up ring 4, oil distribution casing 5 and collar 6.
Described gear 3 is socketed on idler shaft 1 by bearing 2, is respectively equipped with the back-up ring 4 for locating in the both sides of bearing 2.
The fixedly sleeved outer end at idler shaft 1 of described oil distribution casing 5 and being fixed by collar 6, oil leab 11 is provided with in idler shaft 1, oil distribution casing 5 interior edge face offers some oil circuit grooves 51, the oil outlet end of this oil circuit groove 51 is connected with bearing 2, so that lubricant oil can spray to bearing awl and lubricate bearing, the oil inlet end of oil circuit groove 51 is communicated with the oil leab 11 in idler shaft 1.
The structural type of the oil leab 11 in the structure of described oil distribution casing 5 interior edge face oil circuit groove 51 and idler shaft 1 can have multiple.In the present embodiment, in order to increase lubricating efficiency, the oil circuit groove 51 on oil distribution casing 5 is in cross-type; Oil leab 11 in described idler shaft 1 is made up of a vertical passage 111 and two radial passages 112; The import of vertical passage 111 is positioned at the inner of idler shaft 1, and the inlet communication of the outlet of vertical passage 111 and two radial passages 112 in criss-crossing, the outlet of radial passage 112 is communicated with the oil inlet end of the oil circuit groove 51 of cross-type on oil distribution casing 5.
Working principle of the present utility model:
Lubricant oil enters from the inner of idler shaft 1 oil leab 11 vertical passage 111, enters the oil circuit groove 51 of oil distribution casing 5 interior edge face from idler shaft 1 radial passage 112, then sprays to the awl of bearing 2 from oil distribution casing 5 oil circuit groove 51, lubricates bearing 2.
Emphasis of the present utility model is just: adopt oil distribution casing to lubricate bearing.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
