Synchronous toothed belt conveying mechanism

Abstract

The invention discloses a synchronous toothed belt conveying mechanism. The synchronous toothed belt conveying mechanism comprises a first conveying mechanism and a second conveying mechanism which are symmetrically arranged in parallel. Between the first conveying mechanism and the second conveying mechanism, a first transmission shaft is sleeved with a first driving wheel, and a second transmission shaft is sleeved with a second driving wheel. The first transmission shaft and the second transmission shaft are coaxially arranged and form a detachable fixed connection structure. By means of the first transmission shaft and the second transmission shaft which are coaxially arranged and form a detachable fixed connection structure, a channel is formed between the first driving wheel and thesecond driving wheel, and when a synchronous toothed belt needs to be disassembled and assembled, the belt can be loosened only by loosening a first tensioning wheel; and then the belt is taken out orsleeved from the channel between the first driving wheel and the second driving wheel, so that the operation 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
