Description

Technical Field

[0001] The present invention belongs to the technical field of double-speed chains, and in particular relates to a double-speed chain with a built-in stabilizing auxiliary component. Background Art

[0002] The double-speed chain is a special transmission device that is widely used in various mechanical equipment, especially in conveying systems and automated production lines. The characteristic of the double-speed chain is that it can transmit power at different speeds, thereby realizing efficient transportation and processing of workpieces. In the prior art, the key components of the double-speed chain are usually composed of two sprockets of different diameters, a large sprocket and a small sprocket. The double-speed transmission is achieved by adjusting the tooth ratio of the large sprocket and the small sprocket. If the number of teeth on the large sprocket is twice that of the small sprocket, the speed of the chain will be twice the speed of the drive shaft. When the double-speed chain runs at high speed, its performance and life may be affected by vibration, impact and instability. In order to improve the stability and reliability of the double-speed chain, some auxiliary components can be set to help stabilize the operation.

[0003] The existing Chinese patent document with publication number CN107055057B proposes a double-speed chain conveyor line transfer mechanism, which solves the above technical problems by setting a blocking mechanism and embedding a triple-speed guide rail in the blocking block. The triple-speed guide rail has a C-shaped aluminum groove guide rail, so that there will be no jamming when the tooling plate passes through. However, relying entirely on the guide rail and the aluminum groove to limit the double-speed chain may cause wear, and long-term use may lead to deformation.

[0004] Therefore, the present invention proposes a double-speed chain with its own stabilizing auxiliary components, which solves the problem in the prior art that the double-speed chain is completely limited by guide rails and aluminum grooves, which may cause wear and deformation after long-term use. A guide rail designed with an external bevel is used in conjunction with an automatic correction component to regularly correct the running track of the double-speed chain, and a lubrication component is used to regularly lubricate the double-speed chain to reduce wear.
