Roller chain used for external additive production device

Abstract

The present invention provides a roller chain for external additive production equipment, comprising: a pair of left and right inner chain plates, a pair of left and right outer chain plates arranged on the two outer sides of the inner chain plates, press-fitted to the inner chain plates The sleeve in the sleeve hole of the sleeve, the roller freely rotatable on the sleeve, the outer link plate and the pin shaft press-fitted into the pin hole of the outer link plate, a plurality of inner link plates and outer link plates alternately The inner side wall of the inner chain plate is provided with an oil guide groove A corresponding to each sleeve, and the oil guide groove A extends vertically from the upper end of the inner chain plate to the upper surface of the sleeve; the outer surface of the sleeve is provided with a corresponding oil guide groove A Oil guide groove B, oil guide groove B extends horizontally from the upper surface of the sleeve to the middle of the sleeve, and extends from the middle to both sides to form a circular ring; the invention realizes the internal lubrication of the roller chain, which not only saves lubrication It also avoids the greasy feeling after the existing chain is oiled, and keeps the entire chain and the equipment using the chain clean and beautiful.

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...

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
