Problems solved by technology

When the chain unit meshes with the sprocket, the teeth of the sprocket and the chain unit are in line contact through the contact line, and when the contact line just acts on the vertical connection, it will deform the chain unit, so if in order to ensure that the chain is in use Therefore, it is necessary to use a certain method to make the wiring on the back of the chain mesh during assembly, so as to prevent the wiring from directly engaging with the sprocket and causing deformation of the chain unit, which will affect the service life of the chain, but this will lead to low assembly efficiency of the chain.

Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, it is a chain unit of the prior art, the connection line 13 is a vertical straight line consistent with the axis direction of the chain unit 12, and the contact line 14 is also consistent with the axis direction of the chain unit 12 when the sprocket 11 meshes with the chain unit 12 Straight line, if the line 13 is not adjusted to the meshing position of the sprocket 11 and the chain unit 12, when the line 13 is in contact with the contact line 14, the pressure of the contact line 14 will deform the line line 13, thereby affecting the life of the chain.

[0027] Such as Figure 2-6 as shown,

[0028] A chain, comprising a chain unit, the chain unit is composed of a sheet body 001 folded into a circle, the head of the sheet body 001 is provided with a protrusion, and the tail of the sheet body 001 is provided with a dep...

Abstract

The invention discloses a chain. The chain comprises a chain unit. The chain unit is formed through circle folding of a sheet body (001). The head portion of the sheet body (001) is provided with a protrusion, the tail portion of the sheet body (001) is provided with a concave part matched with the protrusion, a connecting line is formed through cooperation of the protrusion and the concave part after the sheet body (001) is subjected to circle folding, and the connecting line is a curve or a broken line or is jointly composed of the curve and the broken line. The chain in which the strength is high, the connecting line does not need to be back onto the chain meshing position, and the assembling efficiency is high is provided.

Description

technical field [0001] The invention relates to the field of automobile engine chain drive, in particular to a chain. Background technique [0002] In recent years, chain transmission has been widely used in the engine field because chain transmission can efficiently transmit power, high-speed chain transmission technology has been continuously matured, and maintenance costs can be reduced at the same time. [0003] During the manufacturing process of the existing chain, the chain unit is manufactured in the form of a blanked coil. By punching the plate and then folding it into a circle, a vertical connection line on the chain unit is formed on the chain unit after the circle is folded. When the chain unit meshes with the sprocket, the teeth of the sprocket and the chain unit are in line contact through the contact line, and when the contact line just acts on the vertical connection, it will deform the chain unit, so if in order to ensure that the chain is in use To ensure...
