Description

A kind of bent axle flexibly

Technical field

The utility model relates to a kind of mechanism member, particularly a kind of bent axle.

Background technique

Bent axle is a kind of conventional mechanism member, be widely used in and comprise in the machinery of electricity generating device, but its effect of existing bent axle is only limited to the transmission of linkage structure, time for the component transmission ridden against on bent axle, wear and tear comparatively serious, meanwhile, the strong point of existing bent axle only has two, thus the less stable of bent axle when rotating.

Summary of the invention

Problem to be solved in the utility model is: provide that a kind of structure is simple, wear-resistant, long service life and rotation time stability strong flexible bent axle.

In order to solve the problems of the technologies described above, flexible bent axle of the present utility model, comprise the first rotating shaft, second rotating shaft and the 3rd rotating shaft, described first rotating shaft, second rotating shaft and the 3rd rotating shaft coaxial, a crankshaft body is provided with between described first rotating shaft and the second rotating shaft, also a crankshaft body is provided with between described second rotating shaft and the 3rd rotating shaft, the two ends, left and right of described every root crankshaft body are all fixedly connected with a link, other one end of described link and the first rotating shaft, second rotating shaft or the 3rd rotating shaft are fixedly connected with, described crankshaft body and the first rotating shaft, second rotating shaft and the 3rd rotating shaft parallel, described link and crankshaft body perpendicular, described two crankshaft body are staggered, described every root crankshaft body is all socketed with more than one bearing, described first rotating shaft, second rotating shaft and the 3rd rotating shaft are equipped with bearing support.

Further, flexible bent axle of the present utility model, a kind of technological scheme is: described link is strip plate, described crankshaft body with between strip plate for key is connected, described first rotating shaft and the 3rd rotating shaft are all fixed with a driving sprocket wheel.

Further, flexible bent axle of the present utility model, another technological scheme is: described link is sprocket wheel, described crankshaft body with between sprocket wheel for key is connected.

The beneficial effect that the utility model obtains is: (1) structure is simple; (2) when be hooked component ride against crankshaft body carries out transmission time, owing to crankshaft body being socketed with more than one bearing, thus component is hooked not directly and crankshaft body connecting part, simultaneously crankshaft body and the relative movement that is hooked between component are for rotate, thus greatly reduce the wearing and tearing of crankshaft body and be hooked the impact force of component to crankshaft body, so wear-resisting property is good, long service life; (3) first rotating shafts, the second rotating shaft and the 3rd rotating shaft are equipped with bearing support, and compared with existing bent axle, bearing support is evenly distributed, thus more stable to the support of whole bent axle, thus whole bent axle is in the process of rotating, compared with existing bent axle, and can be more reliable and more stable; (4) link can be sprocket wheel, thus need not arrange transmission device separately, directly can carry out transmission to whole bent axle by chain, can simplify the structure of bent axle further.

Embodiment

Embodiment 1

As depicted in figs. 1 and 2, the flexible bent axle of the present embodiment, comprise the first rotating shaft 1, second rotating shaft 7 and the 3rd rotating shaft 8, described first rotating shaft 1, second rotating shaft 7 and the 3rd rotating shaft 8 coaxial, a crankshaft body 6 is provided with between described first rotating shaft 1 and the second rotating shaft 7, also a crankshaft body 6 is provided with between described second rotating shaft 7 and the 3rd rotating shaft 8, the two ends, left and right of described every root crankshaft body 6 are all fixedly connected with a link, other one end of described link and the first rotating shaft 1, second rotating shaft 7 or the 3rd rotating shaft 8 are fixedly connected with, described crankshaft body 6 and the first rotating shaft 1, second rotating shaft 7 and the 3rd rotating shaft 8 parallel, described link and crankshaft body 6 perpendicular, described two crankshaft body 6 are staggered, described every root crankshaft body 6 is all socketed with more than one bearing 5, described first rotating shaft 1, second rotating shaft 7 and the 3rd rotating shaft 8 are equipped with bearing support 2, described link is strip plate 4, described crankshaft body 6 with between strip plate 4 for key is connected, described first rotating shaft 1 and the 3rd rotating shaft 8 are all fixed with a driving sprocket wheel 3.

The flexible bent axle of the present embodiment, structure is simple, when be hooked component ride against crankshaft body 6 carries out transmission time, owing to crankshaft body 6 being socketed with more than one bearing 5, thus be hooked component directly with crankshaft body 6 connecting part, while crankshaft body 6 and the relative movement that is hooked between component for rotate, thus greatly reduce the wearing and tearing of crankshaft body 6 and be hooked the impact force of component to crankshaft body 6, so wear-resisting property is good, long service life.

First rotating shaft 1, second rotating shaft 7 and the 3rd rotating shaft 8 are equipped with bearing support 2, and compared with existing bent axle, bearing support 2 is evenly distributed, thus more stable to the support of whole bent axle, thus whole bent axle is in the process of rotating, compared with existing bent axle, and can be more reliable and more stable.

The flexible bent axle of the present embodiment, in the electricity generating device that can be used for the fields such as automobile, train, steamer, agriculture field work, oil field field work and other mechanical structure, applied widely.

Embodiment 2

As shown in Figure 3 and Figure 4, the flexible bent axle of the present embodiment of the present embodiment, described link is sprocket wheel 9, described crankshaft body 6 with between sprocket wheel 9 for key is connected, thus transmission device need not be set separately, directly can carry out transmission to whole bent axle by chain, the structure of bent axle can be simplified further.

Other structure is identical with embodiment 1 with usage.
