Description

Technical Field

[0001] This utility model belongs to the field of chain technology, and in particular relates to a wear-resistant and silent chain. Background Technology

[0002] Chains, as a common transmission component, are widely used in various mechanical equipment. However, traditional chains have some problems during use. First, chains have limited wear resistance and are prone to wear after long-term operation, leading to chain slack, decreased transmission accuracy, and even chain breakage, affecting the normal operation of the equipment. Second, chains generate significant noise during operation, especially at high speeds or under heavy loads. This noise not only interferes with the working environment but may also negatively impact the lifespan of the equipment. Therefore, developing a chain that is both wear-resistant and quiet is of significant practical importance. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a shock-absorbing pad layer on the inner side of the chain plate that can effectively absorb vibration and reduce noise. A grease retainer ring can store grease, maintaining good lubrication of the chain, reducing friction, and further reducing noise in a wear-resistant and quiet chain.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and silent chain, which is composed of multiple chain links connected in sequence. Each chain link includes two parallel chain plates, two pins and two sleeves. The inner surface of the chain plates is provided with a shock-absorbing pad layer, and a grease retaining ring is provided between the pins and the sleeves.

[0005] Preferably, the pins, sleeves, and chain plates are coated with a nano-ceramic coating.

[0006] Preferably, the thickness of the nano-ceramic coating is 0.1-0.3 mm.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] The shock-absorbing pads on the inner side of the chain plates effectively absorb vibrations and reduce noise. The grease retainer ring stores grease, maintaining good lubrication of the chain, reducing friction, and further reducing noise. Attached Figure Description
