Embodiment 1

[0022] The technical solution of this embodiment is: a filter type oil deflecting ring, including an outer ring piece 1, an inner ring piece 2 is arranged in an interference fit inside the outer ring piece 1, and a plurality of oil grooves 3 are opened on the inner wall of the inner ring piece 2, correspondingly Protrusions 4 are arranged between the adjacent oil grooves 3, and the upper end surfaces of the protrusions 4 are arranged obliquely. Several oil return passages 6 are opened on the protrusions 4, and several oil return passages 6 connect the several oil grooves 3 to each other; Channels 6 are arranged staggered along the axial direction of the outer ring piece 1 , and each oil return channel 6 is provided with a filter screen 7 ; the bottom of each oil groove 3 is concave-convex.

[0023] Such as figure 1 As shown, the excess lubricating oil between the oil deflector ring and the motor shaft flows into the nearby oil groove 3, flows into the next oil groove 3 through...

Embodiment 2

[0025] Based on the first embodiment, the technical solution of this embodiment is: the inclination angle of the upper end surface of the bump 4 is 3-6 degrees.

[0026] Such as figure 1 As shown, the inclination angle of the upper end surface of the bump 4 is 3-6 degrees, so that lubricating oil can not only flow into the oil groove 3, but also enable a small amount of lubricating oil between the bump 4 and the motor shaft to lubricate.

Embodiment 3

[0028] Based on the first embodiment, the technical solution of this embodiment is: the upper end surface of the bump 4 is provided with a porous rubber ring 5 .

[0029] Such as figure 1 As shown, the porous rubber ring 5 can store a certain amount of lubricating oil for maintaining lubrication with the motor shaft. Since the porous rubber ring 5 has a certain degree of elasticity, it can realize the sealing of the lubricating oil and prevent the lubricating oil from flowing out Ring, the porous rubber ring 5 can also drain excess lubricating oil to the boss 4, and then flow into the oil groove 3.

Abstract

The invention discloses a filtering type oil deflecting ring, which belongs to the technical field of motor lubricating oil recovery, and comprises an outer ring piece. Protrusions are arranged between the oil grooves, and the upper end surfaces of the protrusions are arranged obliquely. There are several oil return passages on the protrusions, and the several oil return passages connect the several oil grooves to each other; The oil passages are arranged in a staggered manner, each of the oil return passages is provided with a filter screen; the bottom of each oil tank is concave and convex; the invention solves the problem of connecting the oil catcher on the oil retainer ring for the front motor To collect lubricating oil, the lubricating oil deteriorates and cannot be recycled, and the oil deflector ring is easily damaged. It has the advantages of fast and clean oil return.

Description

technical field [0001] The invention belongs to the technical field of motor lubricating oil recovery, and in particular relates to a filter type oil retaining ring. Background technique [0002] The oil deflecting ring is generally used in places where there is oil, but not too much oil, and the excess oil should be blocked back to prevent leakage. It uses the centrifugal force generated by the rotation to throw the oil back to the oil return direction, so it should be placed obliquely towards the oil return direction, that is, the conical surface is used, and the big head is facing the oil return direction. [0003] In labyrinth seals for drive shafts or engine shafts, it must be ensured that the bearings arranged in the bearing bores, which are located above the oil level in the oil sump, are adequately supplied with oil and / or can be rolled over with oil. For continuous lubrication, it is necessary to form a blocking edge on the inner side of the bearing hole, which can...
