A synchronous toothed belt conveying mechanism

Abstract

The invention discloses a synchronous toothed belt conveying mechanism, which comprises a first conveying mechanism and a second conveying mechanism arranged symmetrically in parallel; between the first conveying mechanism and the second conveying mechanism, the first driving wheel sleeve It is arranged on the first transmission shaft, and the second driving wheel is sleeved on the second transmission shaft; the first transmission shaft and the second transmission shaft are arranged coaxially and constitute a detachable fixed connection structure. Through the first drive shaft and the second drive shaft that are coaxially arranged and constitute a detachable fixed connection structure, a channel is formed between the first driving wheel and the second driving wheel. When it is necessary to disassemble and install the synchronous gear When belting, the belt can be loosened only by loosening the first tensioning wheel, and then the belt can be taken out or put on from the channel between the first driving wheel and the second driving wheel, so it is very simple and convenient.

Description

technical field [0001] The invention relates to the technical field of belt conveying, in particular to a synchronous toothed belt conveying mechanism. Background technique [0002] The synchronous toothed belt is referred to as the synchronous belt, also known as the timing belt, which is similar to the common V-belt, flat belt and other belt transmission methods, and is a flexible transmission form. In the prior art, the synchronous toothed belt is generally made of steel wire rope or glass fiber rope as the strength layer, covered with polyurethane or neoprene on the outside, and the inner circumference of the belt is toothed to mesh with the toothed pulley. Since the deformation of the strong layer is small after loading, the circumferential pitch of the toothed belt can be kept unchanged, so there is no relative sliding between the belt and the pulley, thus ensuring synchronous transmission and a stable transmission ratio. Compared with ordinary belt transmission, the ...

Problems solved by technology

[0005] However, although the above-mentioned structure is very convenient for loading and unloading flat belts, it cannot be applied to the synchronous toothed belt conveying mechanism. , when it is installed on the conveying mechanism again, it is difficult to realize the axis coincidence between the driving wheel and the transmission bearing, which is feasible for flat belts, because the installation accuracy requirements are not high, but for installation accuracy The synchronous toothed belt with high requirements will not work

In addition, no matter when removing or replacing the flat belt, it is necessary to pass the flat belt through the entire transmission mechanism (including driving wheels and driving wheels), and these driving wheels and driving wheels are installed on the frame. It is very large, so it is impossible for the flat belt to be inserted from the outside of the frame, so the driving wheel and / or drive wheel can only be removed from the frame, and then put on a new flat belt, and then installed on the frame; Caused the problem of large disassembly and installation workload and complicated process
