Description

Lubricating structure of internal bearing of gear shifting gear box

Technical Field

The application relates to the technical field of gear boxes, in particular to a lubricating structure of an inner bearing of a gear shifting gear box.

Background

In the prior art, a gear-shifting speed-regulating gearbox is a gear-shifting speed-ratio-variable gearbox, and generally has 2 speed ratios; the variable speed ratio key has two pairs of gears meshing with one of the gears in the gear box, and determines which pair of gears participate in the integral transmission through the sliding gear ring.

Disclosure of Invention

The invention aims to provide a lubricating structure of an internal bearing of a gear shifting gearbox. To overcome the defects in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a lubricating structure of gear shifting gear box inner bearing, the inside transmission shaft that is provided with of gear box, the transmission shaft has set gradually first gear, gear shaft and second gear, lubricating structure is including setting up the axial oil circuit in the transmission shaft, the outside gear box that extends of axial oil circuit along the transmission shaft direction links to each other with rotary joint, the axial oil circuit is equipped with flange joint board with gear box body junction cover, flange joint board leads to the oil blanket axle sleeve and links to each other with the end cover of gear box, the oil blanket axle sleeve is provided with the oil blanket with the end cover junction.

Preferably, a first bearing is arranged at the joint of the first gear and the transmission shaft, and a second bearing is arranged at the joint of the second gear and the transmission shaft.

Preferably, the rotation speed of the gear shaft is 2000 r/min.

Preferably, the lubricating structure further comprises a plurality of radial oil holes, and the radial oil holes are connected with the axial oil path.

Compared with the prior art, inside the direct forced entering gear shifting gear of lubricating structure accessible of this application oil pipe, lubricated bearing did not have pressure and flow loss, entered oil pipe in the box outside moreover, monitored pressure and flow easily.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a schematic structural diagram of a lubrication structure of an inner bearing of a shift gearbox according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in a combined drawing 1, the lubricating structure of the bearing inside the gear shifting gearbox is characterized in that a transmission shaft is arranged inside the gear shifting gearbox, a first gear 6, a gear shaft 7 and a second gear 9 are sequentially arranged on the transmission shaft, the lubricating structure comprises an axial oil way 101 arranged in the transmission shaft, the axial oil way 101 outwards extends out of the gear shifting gearbox along the direction of the transmission shaft and is connected with a rotary joint 1, a flange connecting plate 2 is sleeved at the joint of the axial oil way 101 and a gear box body, the flange connecting plate 2 is connected with an oil seal shaft sleeve 3, the oil seal shaft sleeve 3 is connected with an end cover 4 of the gear shifting gearbox, and an oil seal 10 is arranged at.

In this technical scheme, thereby lubricating oil gets into the inside transmission shaft of box through external into oil pipe and lubricates first gear 6, gear shaft 7 and second gear 9, effectively prevents lubricating oil through flange joint board 2 and oil blanket 10 simultaneously and reveals. Simultaneously, the oil inlet pipe is arranged on the outer side of the box body, so that the pressure and the flow can be effectively monitored.

Preferably, a first bearing 5 is arranged at the joint of the first gear + and the transmission shaft, and a second bearing 8 is arranged at the joint of the second gear 9 and the transmission shaft.

Preferably, the rotating speed of the gear shaft 7 is 2000 r/min.

Preferably, the lubricating structure further comprises a plurality of radial oil holes 102, and the radial oil holes 102 are connected with the axial oil passage 101.
