Specific embodiment
As shown in Figure 1, shafting lubricates oil guide structure in automotive transmission, including case of transmission 1, in case of transmission 1
Equipped with bearing chamber 2, fulcrum bearing 3 be located in bearing chamber 2 and integrally formed with case of transmission 1 is equipped in case of transmission 1；
The fulcrum bearing 3, which is equipped with, is flowed into the indoor notch 4 of bearing for lubricating oil, which arranges along the radial direction of fulcrum bearing 3.
The inner wall of case of transmission 1 is equipped with the Oil Guide component integrally formed with the case of transmission 1, case of transmission
1 is formed with Oil Guide component using aluminium integral die-cast, and then using being machined, this oil guide structure is not only optimized
Assembling process solves the problems, such as assembly difficulty, and improves production efficiency, reduces costs.
Oil Guide component is located in bearing chamber 2, and fulcrum bearing 3 is looped around around Oil Guide component, and Oil Guide component includes importing
Component 5 and guide member 6.Lubricating oil is imported into the inner hole of shaft A by introduction part 5, and one end of the introduction part 5 is set to
On the inner wall of case of transmission 1, the other end of introduction part 5 is the free end extended in shaft inner hole.Introduction part 5
Height is greater than the height of fulcrum bearing 3.
The introduction part 5 includes the importing body for being provided with oil transportation channel 52.The importing body includes that circumferential surface is equipped with opening
51 split ring 50, the opening 51 on split ring 50 make opening 51 run through two of split ring along the axially extending of body is imported
Axial end portion.The opening 51 of the split ring 50 is corresponding with the notch 4 in the fulcrum bearing 3.The section of split ring 50 is arc-shaped,
After being provided with opening 51 on split ring 50, the radian of split ring 50 preferentially selects 180 degree, and therefore, split ring 50 is semicircular ring.
