Abstract
The utility model discloses a chain ring with a non-circular section, which comprises a ring crown part and a straight body part, wherein the two sides of the straight body part are provided with the ring crown part, and the sections of the ring crown part and the straight body part are set to be non-circular sections; the non-circular section comprises a circular ring with a hexagonal section, an elliptical ring with a hexagonal section, a circular ring with a rectangular section, an elliptical ring with a rectangular section, a circular ring with a trapezoidal section and an elliptical ring with a trapezoidal section. The utility model has reasonable structure, the non-circular section reduces the contact stress and the torsional freedom degree between the chain links, avoids the winding and knotting of the long chain and improves the working efficiency.
Description
Technical Field
The utility model relates to the fields of ships, maritime work, mining and hoisting, in particular to a chain ring with a non-circular section.
Background
The chain formed by connecting single chain rings can bear larger axial load, and is a common bearing or transmission device in the mechanical engineering industry. The shape of the traditional chain ring is oval or round, the section is usually round, and round steel bars with different diameters are woven. The contact surface of the chain ring in the shape is point contact, the contact stress is large, and under the combined action of the compressive stress and the shearing stress, the crown part of the chain ring can generate stress concentration, so that the bearing capacity is reduced. In addition, because the circular cross-section ring has small contact area and high degree of freedom, the long chain is easy to twist in the using process, and the long chain is knotted and wound, thereby influencing the use.
Chinese patent discloses a flat link for a link chain, patent No.: CN201110418470.6, the standing ring of the chain of this patent has a partially non-circular cross section, but the crown part of the ring is still circular or elliptical in cross section, so it cannot solve the problem of twist knotting.
Disclosure of Invention
The present invention aims to solve the above technical problems and to provide a chain link with a non-circular cross section.
In order to achieve the technical purpose and achieve the technical requirements, the utility model adopts the technical scheme that:
the utility model provides a non-circular cross section chain ring, includes ring crown position, straight body position, its characterized in that: the two sides of the straight body part are provided with annular crown parts, and the sections of the annular crown part and the straight body part are non-circular sections; the non-circular section comprises a circular ring with a hexagonal section, an elliptical ring with a hexagonal section, a circular ring with a rectangular section, an elliptical ring with a rectangular section, a circular ring with a trapezoidal section and an elliptical ring with a trapezoidal section.
Preferably: the inner ring, the top surface, the outer ring and the bottom surface of the annular crown part and the straight body part are all arranged to be planes, and the inner ring is connected with the top surface and the bottom surface through planes or arcs; the outer ring is connected with the top surface and the bottom surface through planes or arcs.
Preferably: the inner ring and the outer ring are arranged in parallel.
Preferably: the top surface and the bottom surface are arranged in parallel.
Preferably: the inner ring and the bottom surface are perpendicular to each other.
Compared with the traditional structure, the utility model has the beneficial effects that: the chain ring structure has the advantages that the structure is reasonable, the contact stress and the torsion freedom degree between the chain rings are reduced due to the non-circular cross section, the long chain is prevented from being wound and knotted, and the working efficiency is improved.
