Flexible drive assembly

Abstract

The present invention involves a flexible transmission component, including a drive hose and a flexible drive axis. The drive flexible hose includes the flexible body, the first and the second connecting pieces. In the flexible hose body there is an axial perforate formed, and the poling part with good flexing resistance is form on the middle of the drive hose. The first connecting piece is integrated with one end of the flexible body and connected with dynamic driving device. The second connecting piece is integrated with the other end of the flexible and connected with dynamic receiving device. The flexible drive axis can deflect and deform and penetrates the axial perforate of the flexible hose. One end is connected with dynamic drive device and the other end is connected with dynamic receiving device. These convert the dynamic that the dynamic drive device outputs from the flexible drive axis to the dynamic receiving device. The poling part can support the flexible hose to avoid excessive bend.

Description

technical field [0001] The invention relates to a transmission assembly, in particular to a flexible transmission assembly. Background technique [0002] Generally, the flexible transmission assembly is mainly used to connect between a power driving device (such as a motor) and a power receiving device (such as a toothed blade of a pruning machine), not only as the power between the power driving device and the power receiving device. The transmission medium can be used to make the power receiving device change the use position (direction or angle) (that is, when the relative position between the power driving device and the power receiving device changes), it can still be controlled by the flexibility of the flexible transmission assembly. characteristics, to ensure that the power of the power driving device can still be transmitted smoothly from the flexible transmission assembly to the power receiving device. [0003] However, as shown in Figure 1, since the flexible tra...

Problems solved by technology

However, since the transmission hose 1 and the flexible transmission shaft 2 often need to be bent during use, and when the bending angle is relatively large, it is easy to cause the bending curvature of the middle section of the transmission hose 1 to be too large (such as As shown in Figure 2), in this way, it is not only easy to cause unnecessary friction between the built-in flexible transmission shaft 2 and the transmission hose 1 at this position, resulting in loss of power, but also the loss of power of the flexible transmission shaft 2. The stress is too concentrated on this excessive bending, and the service life is reduced

[0004] In addition, because this kind of transmission hose 1 must be filled with lubricating oil inside for the lubrication of the flexible transmission shaft 2, but when this kind of transmission hose 1 is poured, the lubricating oil must be injected through the opening at one end, and this This method not only easily causes the lubricating oil to leak out, but also makes it difficult to evenly lubricate the whole process due to the long stroke required for the lubricating oil to be injected.
