Multi-row combined overrunning clutch mechanism for large loads

Abstract

The invention discloses a multi-row combined overrunning clutch mechanism for large loads. The multi-row combined overrunning clutch mechanism for the large loads comprises a main shaft, an inner corewheel sleeve and a multi-row combined overrunning clutch, wherein the inner core wheel sleeve comprises a power output section and a clutch mounting section; the end portion of the main shaft is sleeved with a nonmetal bearing sleeve; the clutch mounting section is installed on the nonmetal bearing sleeve in a sleeving mode; and the multi-row combined overrunning clutch is arranged on the clutchmounting section in a sleeving mode. Due to the adoption of the structure, the multi-row combined overrunning clutch is utilized, double breakthroughs in structure and functionality are realized, andthe clutch has the characteristics of easiness in manufacturing, low cost, convenience in assembly, capability of bearing ultra-large loads and wide application range; and in addition, the axial displacement of the inner core wheel sleeve can be limited by utilizing the nonmetal bearing sleeve, the weight of the nonmetal bearing sleeve is far less than that of a metal part, the reliable connectionbetween all parts is guaranteed, the lightweight design requirement is met, and the dynamic balance stability of the whole mechanism can be guaranteed.

Description

Technical field [0001] The invention relates to the technical field of overrunning clutch devices, in particular to a multi-row combined overrunning clutch mechanism for heavy loads. Background technique [0002] The traditional roller-type overrunning clutch is made of one material. In order to take into account the torsion resistance and wear resistance, the comprehensive selection can only be made in a compromise. Generally, it cannot meet the extreme use scenarios of heavy load and large torque. At the same time, to ensure Reliability, the entire beyond clutch mechanism is usually made of all-metal materials, which cannot meet the requirements of lightweight design. In order to be applicable to the application scenarios of extremely large loads, the existing roller-type overrunning clutches can only bear larger loads by extending the outer ring, inner wheel and rolling elements (rollers). However, the inner wheel and rolling elements cannot be extended indefinitely, especial...

AI Technical Summary

Problems solved by technology

However, the inner wheel and rolling elements cannot be extended indefinitely, especially the thinnest roller, if it is too long, not only prone to uneven force, may cause breakage, but also difficult to guarantee machining accuracy, prone to poor meshing , leading to great difficulty in production, low yield rate, high requirements on materials, and high production costs

Those skilled in the art usually only have a technical background of a single discipline, and do not have comprehensive capabilities in materials, structures, and processes. Therefore, there is currently no overrunning clutch that can use existing conventional materials without greatly increasing the cost. It can meet the application scenarios with super large loads
