The gap of shaft 2 and bearing shell 1 is divided into two at the minimum clearance of bearing shell 19 and maximal clearance by area 3 and diverging region 4, shaft 2
Part, wherein a part is above-mentioned region of convergence 3, and another part is above-mentioned diverging region 4.Specifically, when shaft 2 is counterclockwise
When rotation, the axle center of shaft 2 is located at the axle center lower right-hand side of bearing shell 1, and when shaft 2 rotates clockwise, the axle center of shaft 2 is located at
Lower section, embodiments of the present invention illustrate the knot of the invention so that shaft 2 rotates counterclockwise direction as an example on the left of the axle center of bearing shell 1
Structure and operating status, the region of convergence 3 of oil film are located at the lower part of shaft 2 Yu 1 gap of bearing shell, and diverging region 4 is located at shaft 2 and bearing shell 1
The top in gap.
The inner wall of bearing shell 1 is set there are three oil pocket, respectively the first oil pocket 11, the second oil pocket 12, third oil pocket 13, three oil
Chamber is successively spaced apart along the circumferencial direction of bearing shell 1, wherein the first oil pocket 11 is located at the diverging region 4 of oil film, 12 He of the second oil pocket
Third oil pocket 13 is respectively positioned on the region of convergence 3 of oil film.The opening that each oil pocket is located at 1 inner wall of bearing shell is parallelogram, the first oil pocket
11, the second oil pocket 12, third oil pocket 13 bottom be along the circumferential direction in the arcuate structure of both ends high, middle low.First oil pocket 11,
Second oil pocket 12, third oil pocket 13 inside be equipped with oil inlet 7 and oil outlet 8, the oil inlet 7 and oil outlet 8 are provided with
The lowest part of oil pocket bottom, and it is distributed in along 1 axis direction of bearing shell the both ends of oil pocket.The opening of oil pocket is close to oil outlet 8
Side of the side relative to its oil inlet 7, tilted to the rotation direction of shaft 2.
By taking one of oil pocket as an example, the movement of oil film under working condition is illustrated: lubricating oil via oil inlet 7 into
Enter oil pocket, moved in oil pocket along the rotation direction of shaft 2, and to close to oil outlet 8 side dissipate, into shaft 2 with
Bearing shell moves behind 1 gap along the rotation direction of shaft 2.The oil film in shaft 2 and 1 gap of bearing shell is transported along the rotation direction of shaft 2
When moving to above-mentioned oil pocket, the part oil film close to 1 surface layer of bearing shell enters in oil pocket, along the rotation direction of shaft 2 in oil pocket
Movement, and restrained to the side close to oil outlet 8, bearing shell 1 is discharged by oil outlet 8, it can band by the lubricating oil that oil outlet 8 is discharged
A large amount of heat is walked, the purpose of cooling is played.
The bottom of three oil pockets is equipped with sliding coated areas 5, and sliding coated areas 5 covers each oil pocket and is located at oil inlet 7 and goes out
The link position of hydraulic fluid port 8 is biased to the rotation direction side of shaft 2, and extends to the open edge of oil pocket.Positioned at the of region of convergence
Corresponding oil pocket is extended in sliding coated areas in two oil pockets 12 and third oil pocket 13, the rotation direction along shaft 2,
Sliding coating extension area 6 is formed on 1 inner wall of bearing shell, the sliding coated areas 5 and the coating for sliding coating extension area 6 are the painting of fluorine carbon
Layer.Sliding coating extension area 6 is covered in the inner surface of bearing shell 1, and outer profile is right-angled trapezium, slides the oblique of coating extension area 6
