A multifunctional modular shaft

Abstract

The invention discloses a multifunctional modular rotating shaft, relates to the field of medical crane rotating shafts, and solves the problems that a conventional rotating shaft is complicated in assembling, high in difficulty and long in time, a limiting piece is complicated and non-economic in design, the overall structure is not compact, and an electromagnetic brake cannot be alternatively assembled. The multifunctional modular rotating shaft comprises an outer rotating shaft ring and an inner rotating shaft ring, wherein the outer rotating shaft ring is of an overall forged structure with a flange; the inner rotating shaft ring is of an overall forged structure with a flange; connection holes are formed in the top surface of the flange of the outer rotating shaft ring; limiting indexing holes, limiting blocks and a mechanical braking acting surface are arranged on the outer rotating shaft ring; mechanical braking holes, braking component clamping slots and limiting columns are arranged on the inner rotating shaft ring. By the adoption of an embedding method for arranging the limiting blocks and the limiting columns, the overall structure is compact, the whole size and the weight of the rotating shaft are reduced, the design is modularized, the rotating shaft assembling time is shortened, and an air bag brake and the electromagnetic brake can be alternatively assembled. The multifunctional modular rotating shaft is suitable for the field of medical instruments.

Description

technical field [0001] The invention relates to the field of medical pendant rotating shafts, in particular to a multifunctional modular rotating shaft. Background technique [0002] At present, the product structure of the rotating shaft of the medical pendant is as follows. An independent bearing is installed between the inner ring and the outer ring of the rotating shaft. The lower end of the inner ring of the rotating shaft is connected with a flange through threads, and the upper surface of the flange is fixed with an airbag brake, a mechanical brake and a limiter. There is an indexing threaded hole on the outer circumferential surface of the outer ring of the rotating shaft, which is used to install another part of the limit. When assembling the large nut of the rotating shaft and connecting the lower flange, special tooling and high-torque electric wrench are required. The processing accuracy of the bearings installed on the inner ring and outer ring of the rotating s...

AI Technical Summary

Problems solved by technology

When assembling the large nut of the rotating shaft and connecting the lower flange, special tooling and high-torque electric wrench are required. The processing accuracy of the bearings installed on the inner ring and outer ring of the rotating shaft is relatively high, so the cost of materials and total assembly time is also high. ;The setting of the limit on the outer circumferential surface is not only inconvenient to process, but also affects the compactness of the size; the design of the limit is more complicated and uneconomical; the overall height of the structure is high, and the electromagnetic brake cannot be selected
