Problems solved by technology

The existing chain and sprocket adopt a fixed fit, that is, the position of the chain and the sprocket is fixed. In this way, when the chain and the sprocket are meshed and running, the chain will be loaded. After a long time, the chain will be stretched and the chain will become loose. , eventually the chain and the sprocket cannot mesh well, which greatly affects the transmission efficiency and poor stability. In serious cases, the chain skips teeth and finally leads to transmission failure

Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the drawings.

[0021] Such as Figure 1 to Figure 3 As shown, a flexible chain tensioning structure according to the present invention includes a chain 1, a sprocket 2 and a sprocket seat 12, and the sprocket 2 engages and drives with the chain 1 through sprocket 13 in cooperation. A supporting shaft 4 is formed on one side of the sprocket seat 12, and the sprocket 2 is rotatably arranged on the supporting shaft 4 through a bearing 3. The sprocket seat 12 is slidably arranged on the guide rail 5, the guide rail 5 is fixedly arranged on the front block 11, and one end of the sprocket seat 12 is connected with a tension buffer mechanism. The above structure constitutes the main structure of the present invention.

[0022] Wherein, the tension buffer mechanism includes a rear stop 9 and a guide post 8 fixedly connected to one end of the sprocket seat 12, the guide post 8 is horizontally arranged in the...

Abstract

The invention relates to the technical field of chain tensioning, in particular to a flexible chain tensioning structure which comprises a chain, a chain wheel and a chain wheel base, wherein a supporting shaft is formed on one side of the chain wheel base, the chain wheel is rotatably arranged on the supporting shaft through a bearing, the chain wheel base is arranged on guide rails in a sliding mode, the guide rails are fixedly arranged on a front stop block, and one end of the chain wheel base is connected with a tensioning buffer mechanism. When the chain and the chain wheel are in matched transmission, the tensioning buffer mechanism timely adjusts the positions of the chain wheel and the chain wheel base, accordingly the technical purpose of load between the chain and the chain wheel is achieved, chain slippage and even chain transmission failure are effectively avoided, and stability is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of chain tensioning, in particular to a chain flexible tensioning structure. Background technique [0002] The matching structure of the chain and the sprocket is widely used in the mechanical field and is well known by people. The existing chain and sprocket adopt a fixed coordination, that is, the position of the chain and the sprocket is fixed. This arrangement will load the chain when the chain and the sprocket are engaged. After a long time, the chain will be stretched, causing the chain to loosen In the end, the chain and the sprocket cannot be meshed well, which greatly affects the transmission efficiency and poor stability. In severe cases, the chain skips teeth and finally causes transmission failure. Therefore, it is necessary to effectively improve the existing chain and sprocket structure to improve stability and transmission efficiency. Summary of the invention [0003] The purpose of the present in...
