A method for manufacturing a wear-resistant layer of a highly wear-resistant chain and a method for manufacturing the wear-resistant sleeve of an oil-free bearing

Abstract

The invention discloses a high-abrasion-resisting chain, a manufacturing method for an abrasion resisting layer of the high-abrasion-resisting chain and a manufacturing method for an oilless bearing abrasion-resisting sleeve of the high-abrasion-resisting chain. The high-abrasion-resisting chain comprises a chain base and a chain body hinged to the chain base in a matched manner. The two ends of a connecting sleeve of the chain body are right opposite to connecting holes correspondingly formed in the chain base. A shaft pin is arranged in the connecting holes and inserted in the connecting sleeve. The abrasion-resisting layer is arranged between the pin shaft and the connecting sleeve and comprises a base layer and a self-lubrication powder layer pressed on the base layer, and the base layer is a 316 stainless steel net. Compared with a traditional boarding machine chain, the oiling-free self-lubrication chain has the main beneficial effect that under the conditions of high temperature and heavy loads, the abrasion resisting relative to a friction part is greatly improved. The service life of the boarding machine chain under the high-speed running state is greatly prolonged. Through the improvement, external oiling is avoided, the problem of oil pollution is solved, and meanwhile the maintaining and using cost of printing and dyeing enterprises is greatly reduced; and due to the fact that shutdown for oiling is not needed, the using efficiency and the energy utilizing efficiency of a boarding machine can be effectively improved.

Description

technical field [0001] The invention relates to the field of high-speed setting machines of printing and dyeing machinery, in particular to chains on the setting machines. Background technique [0002] Due to the substantial increase in the running speed of the setting machine, new requirements are put forward for the wear resistance of the chain. The chain that can be used for one year on an ordinary low-speed setting machine can only meet 3-6 months of use on a high-speed setting machine. requirements, and the price of imported high-temperature-resistant grease for setting machine chains is very expensive, and the industry compares it to "soft gold". This has greatly restricted the development of my country's high-speed setting machine business and increased the use and maintenance costs of printing and dyeing enterprises. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a high wear-resistant chain with low manufactu...

[0002] Due to the substantial increase in the running speed of the setting machine, new requirements are put forward for the wear resistance of the chain. The chain that can be used for one year on an ordinary low-speed setting machine can only meet 3-6 months of use on a high-speed setting machine. requirements, and the price of imported high-temperature-resistant grease for setting machine chains is very expensive, and the industry compares it to "soft gold"

This greatly limits the development of high-speed setting machine business in China and increases the maintenance cost of printing and dyeing enterprises.
