Embodiment Construction

[0072] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0073] see figure 1 , Figure 1D , Figure 1F As shown, a reed-based spiral cross flexible bearing of the present invention includes an upper end cover 1, a lower end cover 2, an upper reed 3, a middle reed 4, a lower reed 5 and a tapered pin (that is, the first A conical pin 3A, a second conical pin 3B, a third conical pin 4A, a fourth conical pin 4B, a fifth conical pin 5A, a sixth conical pin 5B);

[0074] After the upper end cover 1 and the lower end cover 2 are assembled, a spiral gap 6 is formed, see figure 1 , Figure 1A , Figure 1B , Figure 1C As shown; the upper reed 3, the middle reed 4 and the lower reed 5 are installed in the cavity formed inside the upper end cover 1 and the lower end cover 2 through tapered pins;

[0075] The upper end cover 1 has the same structure as the lower end cover 2, see Figure 5 , Figure 6 shown;

Abstract

The invention discloses a spiral cross flexible bearing based on a reed. The bearing comprises an upper end cover, a lower end cover, an upper reed, a middle reed, a lower reed and taper dowels, wherein the upper end cover and the lower end cover are assembled so as to form a spiral gap, and the upper reed, the middle reed and the lower reed are installed on a cavity formed in the upper end cover and the lower end cover. The bearing provided by the invention utilizes the three reeds with same structure to sequentially spirally cross and combine in space so as to match with the upper and lower bearing end covers, the flexible bearing which has the advantages of large stroke, large radial direction and very compact axial rigidity structure is formed, and meanwhile, the flexible bearing has higher movement resolution and precision. The bearing provided by the invention based on the upper and lower bearing end covers is matched to install reeds with different structural styles so as to deploy the flexible bearing with different properties, and the bearing meets different application fields.

Description

technical field [0001] The present invention relates to a bearing, and more particularly, to a reed-based helically crossed flexible bearing. Background technique [0002] Bearings are components used to determine the relative movement position of the rotating shaft and other parts, and play a supporting or guiding role. The flexible bearing is a special bearing different from the rigid bearing. Its working principle is to use the flexible unit to deform under the action of external force to generate relative rotation. Flexible bearings have many obvious advantages that rigid bearings do not have: no friction; no gap; self-centering; no lubrication; no maintenance; long life; simple installation; vacuum application, etc. It is precisely because of these advantages that flexible bearings are favored by researchers engaged in precision positioning, micro-motion platforms and other precision fields. It is used in adjustment mechanism, alignment mechanism of microwave antenna ...
