Problems solved by technology

[0004] However, because the outer peripheral surface of the chain shaft in the past is a smooth and flat surface, when the lubricating oil is added to the joint part of the chain, it is easy to be lost and spilled, and the lubricating effect is not easy to last, which often results in rapid wear and shortened service life of the chain components.

Abstract

The invention relates to a chain shaft of a chain and a manufacturing method of the chain shaft. The chain shaft of the chain comprises two end faces located at the two opposite ends of the central axis in a spaced mode, a peripheral face around the central axis and a plurality of oil storage grooves, wherein the oil storage grooves surround the central axis respectively and sink from the peripheral face to the central axis at intervals, and the periphery of each oil storage groove is closed and is not communicated with the end faces and the other oil storage grooves. When the chain shaft is installed on the chain, the oil storage grooves can enlarge the oil storage space of the chain so as to improve the smoothness and the abrasion resistance in operation of the chain, and meanwhile the service life of the chain can be prolonged. The manufacturing method of the chain shaft of the chain includes the blank knurling step, a blank is knurled in a rolling mode to form the chain shaft, and thus the chain shaft is easy to machine and form in the manufacturing process.

Description

technical field [0001] The invention relates to a chain shaft and a manufacturing method thereof, in particular to a chain shaft of a chain with several oil storage grooves recessed on the outer peripheral surface and a manufacturing method thereof. Background technique [0002] Generally, the design of the chain is usually composed of several series units connected in series to form a ring shape. Each series unit roughly includes: two inner chain pieces facing each other at intervals, and two inner chain pieces located on the outside of the inner chain pieces respectively. an outer chain piece, a chain shaft inserted into the inner chain piece and connected to the outer chain piece at both ends, and a bushing used to combine with the inner chain piece and sleeved on the periphery of the chain shaft, And a chain roller sleeved on the periphery of the bush. [0003] The bushing and the inner chain piece form a combined body, the chain shaft and the outer chain piece are conn...
