Abstract
The utility model belongs to the technical field of mechanical transmission components, and provides a chain which solves the problem that connection firmness of an existing chain is poor. The chain comprises an inner chain sheet a, an inner chain sheet b and an outer chain sheet. A chain rolling table is arranged on one side of the inner chain sheet a, a self-lubricating layer is arranged on the chain rolling table in the circumference direction, a limiting table is arranged on the chain rolling table, hinge pins are arranged on the other side of the inner chain sheet a and the limiting table, the hinge pins have a certain draft angle, a limiting hole is formed in the inner chain sheet b, a connecting hole is formed in the outer chain sheet, the diameter of the limiting hole is equal to that of the limiting table, and the diameter of the connecting hole is slightly smaller than that of the hinge pins. Therefore, in the process of chain assembly, riveting on the hinge pins by a riveting machine is not needed, the problem of damage on the outer chain sheet is avoided, and the situations that the hinge pins and the outer chain sheet are disengaged and interlocking force of the chain is insufficient can be avoided. In addition, the outer chain sheet and the hinge pins are combined loosely, and therefore the chain can rotate more freely.
Description
Technical field
The utility model belongs to the mechanical transmission component technical field, relates to a kind of chain.
Background technique
Chain is in industrial and agricultural production, uses very extensively in people's daily life, and traditional chain all adopts bearing pin that inside and outside chain sheet is formed by connecting.Die is a kind of mode that the end face at chain hinge pin two ends is made its increase external diameter by the mode of extruding.Die has very important effect to the fastness of whole chain, and it has strengthened the link fastness of bearing pin and chain sheet further, prevents that outer chain sheet from coming off.The chain of using at present, general employing two limit rivetings, it is the mode of edge by pushing with pin roll end face, formation has the distortion of several angle, thereby increase the external diameter of end part of pin shaft, increase the fastness of bearing pin and chain sheet, its advantage is that efficient is high, still can't satisfy the Environmental Conditions that the degree of being connected firmly to chain and bearing pin has higher requirements.
The model utility content
For addressing the above problem, the utility model provides a kind of chain.
Concrete solution is: a kind of chain, comprise inner chain sheet a, inner chain sheet b and outer chain sheet, inner chain sheet a one side is provided with chain and rolls platform, chain rolls and is provided with limit dais on the platform, is provided with bearing pin on inner chain sheet a opposite side and the limit dais, and described bearing pin has certain drafting angle, be provided with spacing hole on the described inner chain sheet b, be provided with attachment hole on the described outer chain sheet, described spacing hole diameter is identical with limit dais, and described attachment hole diameter is slightly less than pin diameter.
Further, described chain rolls and platform week upwards is provided with self-lubricating layer.
The utility model is in the process of chain assembling, need not to use riveting machine that bearing pin is riveted, avoid occurring damaging the problem of outer chain sheet, and the chimeric hypodynamic situation of the disengagement of bearing pin and outer chain sheet and chain of can stopping occurs, in addition, owing to make up for loosening between this outer chain sheet and the bearing pin, so that the rotation of chain is more flexible.

Fig. 1 is the structural representation of this practicability.
Wherein:
1. inner chain sheet a 2. inner chain sheet b 3. outer chain sheets 4. chains roll platform
5. limit dais 6. bearing pins 7. spacing holes 8. attachment holes
Embodiment
A kind of chain, comprise inner chain sheet a1, inner chain sheet b2 and outer chain sheet 3, inner chain sheet a1 one side is provided with chain and rolls platform 4, chain rolls and is provided with limit dais 5 on the platform 4, is provided with bearing pin 6 on inner chain sheet a1 opposite side and the limit dais 5, and described bearing pin 6 has certain drafting angle, be provided with spacing hole 7 on the described inner chain sheet b2, be provided with attachment hole 8 on the described outer chain sheet 3, described spacing hole 7 diameters are identical with limit dais 5, and described attachment hole 8 diameters are slightly less than bearing pin 6 diameters.
Described chain rolls and 4 weeks of platform upwards is provided with self-lubricating layer.
The utility model is in the process of chain assembling, need not to use riveting machine that bearing pin is riveted, avoid occurring damaging the problem of outer chain sheet, and the chimeric hypodynamic situation of the disengagement of bearing pin and outer chain sheet and chain of can stopping occurs, in addition, owing to make up for loosening between this outer chain sheet and the bearing pin, so that the rotation of chain is more flexible.
