Oily structure 305 is received in setting in the upper shell of i.e. two jackshaft second bearing mounting holes 303 at shell, is received oily structure 305 and is
Hook formation is collected and is directed in the site of engagement between said gear by receiving oily structure 305 lubricating oil to get up that will splash
Portion.
Referring to Fig.1 0, the course of work of preceding lubricating system is as follows:
After transmission internal fills a certain amount of lubricating oil, the front and rear row gear on lower jackshaft 9 is submerged in pasta
Under, there is no problem for the lubrication of gear and bearing.After gearbox starts normal operation, input shaft drives the 4th gear thereon
10 start to rotate, and have splashed on a large amount of lubricating oil to the inner wall of speed changer procapsid 2, by being arranged in speed changer procapsid 2
Preceding fuisw rib 206 on wall is pooled to the lubricating oil of inner wall constantly in three oil-feed tanks 205, in three oil-feed tanks 205
Before lubricating oil separately flows into two first before fuel feed hole 201 and one second in fuel feed hole 207, then flow separately through on procapsid 1
Preceding oil groove of crossing reach the first groove 104,105, two jackshaft first bearing mounting holes 203 of input shaft oil seal mounting hole and defeated
Enter and stored in axle bearing mounting hole 204, and to the bearing and oil sealing being arranged in each bearing mounting hole and seal mounting hole
It is lubricated.When the lubricating oil height stored in two the first grooves 104 is higher than the entrance height of two preceding Connectivity Sections 102,
Lubricating oil in two the first grooves 104 will flow into input shaft oil seal mounting hole 105 along two preceding Connectivity Sections 102.Work as input
Lubrication when lubricating oil in shafting oil seal installation hole 105 is higher than the entrance of preceding outlet section 103, in input shaft oil seal mounting hole 105
Oil is entered inside gear box casing by the preceding oil return hole 202 on speed changer front housing 2, so circulation can constantly to bearing and
Oil sealing is lubricated, and takes away related heat, guarantees its normal operation.
Lubricating system is identical with preceding lubricating system to the greasing of bearing with oil sealing afterwards, herein no longer narration in detail.
The transmission lubrication system is as follows to the greasing of each gear:
It can since the 4th gear 10 of the input shaft being partially immersed under pasta is sufficiently large for front-seat gear engagement place
To pass through the site of engagement for lubricating this to gear pair that self splashes.For rear gear engagement place, will be flown by receiving oily structure 305
The lubricating oil come is splash to collect and lubricating oil is guided to 6 mesh regional of first gear 5 and second gear, second gear 6 respectively
It is lubricated with 7 engaging section region of third gear, guarantees that its high-speed smooth operates.
The above description is only an embodiment of the present invention, is not intended to limit protection scope of the present invention, all to utilize this hair
Equivalent structure transformation made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant technical fields,
It is included within the scope of the present invention.
