Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to a self-lubricating oil storage tank for excavator bucket shafts. Background Technology

[0002] The excavator bucket shaft is a key component in the excavator's working device that withstands high-frequency rotation and reciprocating motion. Its surface is in direct contact with mating parts such as bushings and bearings. Under heavy load, high speed, or frequent start-stop conditions, the direct friction between the metals generates a large amount of heat, leading to surface wear, deformation, or even seizing. Lubricating oil or grease forms an oil film on the contact surface, separating the metal surfaces and converting sliding friction into fluid friction, significantly reducing the coefficient of friction, thereby reducing wear and energy loss. The lubricant carries away heat through circulation, and its high specific heat capacity and thermal conductivity help maintain the bucket shaft's working temperature within a reasonable range, avoiding changes in the fit clearance or jamming caused by thermal deformation.

[0003] According to a patent published on the China Patent Network, the patent title is "A Bucket for an Excavator Device," patent application number 201811461481.0. This invention discloses a bucket for an excavator device, belonging to the field of excavators. The bucket includes a bucket and a mounting plate. A pair of strip-shaped through holes are respectively opened on both sides of the bucket. Three first positioning pins are fixedly connected to both sides of the bucket, arranged in a triangular pattern. A first connecting rod and a second connecting rod are respectively provided on both sides of the bucket. Collars are fixedly connected to both ends of the first and second connecting rods. The collars at one end of the first and second connecting rods are stacked and fitted onto the first positioning pin located in the middle. The collars at the other ends of the first and second connecting rods are respectively fitted onto the other two first positioning pins. A first nut is threaded onto the outermost side of each of the three first positioning pins. A pair of protrusions are fixedly connected to the front end of the mounting plate, which can increase the capacity of the excavator bucket. However, the above-mentioned excavator bucket cannot perform self-lubrication at the shaft, requiring manual lubrication by the operator, which is inconvenient in use.
