Problems solved by technology

[0002] Part of the rotating structure of the existing storage forklift (such as the steering handle), there is no rotation damping between the shaft and the hole in the structure, so the frictional resistance between the shaft and the hole is very small when turning, and the turning effect is not good.
Some manufacturers reduce the fit gap between the shaft and the hole, but this will cause rotation noise and wear problems; some manufacturers add nylon pads at the end of the shaft, and then use the end cover to compress, but due to the compression force of the end cover The direction is not radial, so the damping effect is not good

Embodiment Construction

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0011] Such as figure 1 As shown, a rotation damping device includes a rotating shaft 1 and a rotating seat 2 that rotates with the rotating shaft 1. The inner wall of the rotating seat 2 is provided with an annular groove, and a guide belt 3 is provided in the annular groove, and the guiding belt 3 rotates with the rotating shaft 1. Friction fit; wherein, the guide belt 3 is a wear-resistant belt made of polytetrafluoroethylene.

[0012] The rotating base 2 is radially provided with through threaded holes, and a jacking wire 4 is arranged in the threaded hole, and the jacking wire 4 leans against the outer wall of the guide belt 3 .

[0013] The rotation damping de...

Abstract

The invention discloses a rotary damping device. The rotary damping device comprises a rotating shaft and a rotating base rotationally matched with the rotating shaft; an annular groove is formed in the inner wall of the rotating base; a guide belt is arranged in the annular groove, and is in rotary friction fit with the rotating shaft; the rotating base is radially provided with a through thread hole; and a jackscrew is arranged in the thread hole, is ejected against the outer wall of the guide belt, and presses the guide belt and the rotating shaft. The rotary damping device presses the guide belt on the outer wall of the rotating shaft through the jackscrew, so that the rotating shaft and the guide belt form rotary friction fit to generate a certain damping, and such advantages as wear resistance and silence are achieved; and the elasticity of the guide belt can be adjusted through the jackscrew, so that the damping magnitude is adjusted, and the damping effect between the rotating shaft and the rotating base is greatly improved.

Description

technical field [0001] The invention relates to a forklift accessory, in particular to a rotation damping device. Background technique [0002] The partial rotation structure (such as the steering handle) of the existing storage forklift has no rotation damping between the shaft and the hole in the structure, so the frictional resistance between the shaft and the hole is very small when turning like this, and the rotation effect is not good. Some manufacturers reduce the fit gap between the shaft and the hole, but this will cause rotation noise and wear problems; some manufacturers add nylon pads at the end of the shaft, and then use the end cover to compress, but due to the compression force of the end cover The direction is not radial, so the damping is not good either. Contents of the invention [0003] In order to solve the above technical problems, the present invention discloses a rotation damping device, which includes a rotating shaft and a rotating seat that rota...
