Roller chain for admixture production facility

Abstract

The invention provides a roller chain for an admixture production facility. The roller chain comprises a pair of left and right inner chain plates, a pair of left and right outer chain plates disposed on two outer sides of the inner chain plates, sleeves press-fitted in sleeve holes of the inner chain plates, rollers capable of freely rotating on the sleeves, and pin shafts press-fitted in pin holes of the outer chain plates. A plurality of inner chain plates and outer chain plates are connected alternately. An oil guiding groove A is formed in an inner sidewall of each inner chain plate in such a manner of corresponding to each sleeve, and vertically extends to an exact upper surface of the sleeve from an upper end of the inner chain plate; an oil guiding groove B is formed in an external surface of each sleeve in such a manner of corresponding to the oil guiding groove A, and horizontally extends to the middle of the sleeve from the upper surface of the sleeve and further extends from the middle to two sides into a circular ring shape. The roller chain for the admixture production facility allows internal application of lubricating oil thereto; not only is the lubricating oil saved, but also greasy appearance of an existing chain after oil application is avoided, and the whole chain and the facility using the chain are kept clean and pleasing to the eye.

Description

technical field [0001] The invention relates to the field of basic spare parts of mechanical equipment, in particular to a roller chain for external additive production equipment. Background technique [0002] As the basic component of transmission, the chain is widely used in various mechanical equipment. In order to smooth the transmission of the chain and reduce the wear and tear between the chain parts, the chain needs to be lubricated. The existing methods for lubricating the chain all use a brush or cloth to brush the lubricating oil on the outer surface of the chain, and then make the chain move so that the lubricating oil penetrates into the inner surface of the roller. The disadvantages of this method are: one, in order to penetrate the lubricating oil into the inner surface of the roller, a lot of lubricating oil needs to be brushed on the outer surface of the chain, and a lot of lubricating oil is wasted; two, the outer surface of the chain is all wiped With lubr...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: one, in order to penetrate the lubricating oil into the inner surface of the roller, a lot of lubricating oil needs to be brushed on the outer surface of the chain, and a lot of lubricating oil is wasted; two, the outer surface of the chain is all wiped With lubricating oil, it is easy to be stained with dust and sand, which will affect the normal operation of the chain, and the unsightly appearance will also affect the cleanliness of the entire equipment
