Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
As shown in fig. 1 and 3, a novel oil pumping mechanism comprises: an oil collector 1 and an oil pump rotor 2.
As shown in fig. 3 and 4, the oil collector 1 comprises a shell 105 and an oil inlet 101, the position of the oil collector 1 is kept fixed, and the oil inlet 101 is aligned with or connected with an oil collecting point of splashed oil; the main body part of the shell 105 is annular, the center of the shell is provided with a volume cavity 104, the center of the shell is open, and the oil collector 1 is internally provided with an oil pump rotor 2; the oil collector 1 is further provided with a plurality of compression parts 103 which are uniformly distributed in the circumferential direction, and the compression parts 103 are contracted inwards relative to the annular parts to form a volume compression cavity. The compression portion 103 of the oil collector 1 is curved or planar with inward depressions. The housing 105 of the oil collector 1 is provided with a clamping part which is in an incomplete ring shape and is matched with a pressing plate arranged on a shaft for positioning.
As shown in fig. 2, the oil pump rotor 2 is installed inside the oil collector 1, rotates relative to the oil collector 1, a plurality of evenly arranged convex claws 202 are arranged on the outer side of the ring body 203, the number and positions of the convex claws 202 are in one-to-one correspondence with the compression parts 103 of the oil collector 1, oil passage holes 201 are formed in the convex claws 202, oil is introduced into the inner side of the ring body 203, the ring body 203 is matched with a shaft, and a groove formed in the shaft flows into the shaft.
In one example, a relief notch 102 corresponding to the claw 202 is provided on one side of the oil collector 1, which is convenient for installation. The oil pump rotor 2 is provided with four convex claws 202 which are uniformly distributed around the center of the oil pump rotor 2; the oil collector 1 is provided with four relief notches 102 corresponding thereto.
The working principle of the utility model is as follows:
according to the novel oil pumping mechanism, 4 abdication notches 102 are formed in the end face of one side of the oil collector 1, so that the oil pump rotor 2 is convenient to install. The oil collector 1 shell 105 is convenient to be attached to the pressing plate and the end face of the bearing on the input shaft, so that axial positioning is realized. The oil collector 1 has 4 volume compression chambers in the circumferential direction, and when the oil pump rotor 2 rotates to this position, the volume is reduced, and the lubricating oil flows into the oil pump rotor 2. The oil pump rotor 2 has 4 claws 202, and the claws 202 have an oil passage hole 201 for facilitating the inflow of lubricating oil.
