Problems solved by technology

If there is a gap between the support vane and the inner wall of the metal outer tube, the jamming phenomenon between the support vane and the metal outer tube can be avoided, but the support tube is prone to co-rotation with the rotating flexible shaft, and the outer end of the support vane constantly rubs against the inside of the metal outer tube. The wall generates vibration, reduces operating comfort, and emits huge noise pollution, which is not conducive to environmental protection requirements

Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0009] As shown in the figure: the rotating flexible shaft support tube of the present invention is mainly composed of an inner tube body 1 and a support blade 2 .

[0010] The present invention includes that the inner tube body 1 and the outer wall surface of the inner tube body 1 are integrally provided with three or more support blades 2, and the support blades 2 extend along the length direction of the inner tube body 1 on the outer wall surface of the inner tube body 1. , the supporting blades 2 intersect with the inner tube body 1 at an acute angle, the cross section of the supporting blades 2 is arc-shaped, all the supporting blades 2 rotate in the same direction, and the supporting blades 2 have a shape of gradually decreasing thickness from their bottom end to their top end .

[0011] The supporting blades 2 are three, four, five or six, and they are ...

Abstract

The invention relates to a rotary flexible shaft support pipe; according to the technical proposal provided by the invention, the rotary flexible shaft support pipe comprises an inner pipe body and three or more than three support vanes integrally arranged on the external wall surface of the inner pipe body; the support vanes extend on the external wall surface of the inner pipe body along the length direction of the inner pipe body; the support vanes are in acute angle intersection with the inner pipe body; the section of each support vane is arc-shaped; all the support vanes have the same rotational direction; the thickness of each support vane gradually becomes smaller from the bottom end to the top end of each support vane; the rotary flexible shaft support pipe is used to have the advantages of avoiding the following rotation situation, reducing vibration, comfortable operation, avoiding the deadlock of the inner pipe body and the rotary flexible shaft, improving the service life greatly, simple replacement and reducing the cost.

Description

technical field [0001] The invention relates to a rotating flexible shaft support pipe. Background technique [0002] In lawn mowers and scarifiers of plant protection machinery, support tubes must be used to support the rotating flexible shaft. When in use, the support tubes are inserted into the metal outer tube. At present, a general support tube is mainly composed of an inner tube body and support vanes fixedly arranged on the outer wall of the inner tube body. The radial directions of the support vanes and the inner tube body are consistent, and the top and bottom ends of the support vanes have uniform thickness. During installation, in order to ensure the stable insertion of the support blades in the metal outer tube, the distance between the outer end of the support blades and the center of the inner tube body is slightly larger than the inner diameter of the metal outer tube, so that the inner tube body in the installed support tube has been inserted Deformation whe...
