Description

Chain sleeve

Technical Field

The utility model relates to a chain technical field specifically is a chain sleeve.

Background

The chain is a key part of the modern chain transmission device for improving the mechanical performance, and can form a compact whole body at the connection part of one machine. And the movable chain appears in China as early as the second century of the Gregorian, and the chain wheel transmission principle is successfully applied to the dumper created by Todhiran Bilan at that time. The square plate blade chain type water wheel can be used as an original chain type transmission device, a driving chain is mainly divided into a roller chain, a tooth-shaped chain and the like, wherein the roller chain is most widely applied, parts of the chain are made of carbon steel or alloy steel and are subjected to heat treatment, so that the chain has the characteristics of high strength, wear resistance and impact resistance, the roller chain can be made into a single-row chain and a multi-row chain, and when high power is transmitted, the double-row chain or the multi-row chain can be adopted. The bearing capacity of the multi-row chain is in direct proportion to the row number, but the load born by the side-by-side chain is not easy to be uniform due to the influence of precision, so the row number is not suitable to be too large. The chain comprises an inner chain plate, an outer chain plate, a pin shaft, a sleeve and a roller, wherein the inner chain plate is fixedly connected with the sleeve, the outer chain plate is fixedly connected with the pin shaft through interference fit, and the inner chain plate and the sleeve are called as inner chain links and outer chain links; the roller is in clearance fit with the sleeve, and the sleeve is in clearance fit with the pin shaft. When the inner chain plate and the outer chain plate are relatively deflected, the sleeve can freely rotate around the pin shaft. The roller is movably sleeved on the sleeve, and when the roller works, the roller rolls along the tooth profile of the chain wheel, so that the abrasion of the gear teeth can be reduced. The main wear of the chain occurs at the contact surfaces of the pin and the bushing, so that a small gap should be left between the inner and outer chain plates to allow the lubricating oil to penetrate between the friction surfaces. The link plate is generally made into a '8' shape so that each cross section of the link plate has nearly equal tensile strength, and the mass and the inertia force during movement of the link are reduced, wherein a chain sleeve is one of the parts forming the link chain, which plays an important role in the chain formation, but the existing chain sleeve still has the problems of poor connection stability and insufficient structural strength of the contact surface in the actual use process. To this end we propose a chain bushing to solve these problems.
