Conical gear shaft twisting-stopping simulation structure device and application

Abstract

The invention provides a conical gear shaft twisting-stopping simulation structure device. The device comprises a fixed disk, a friction twisting-stopping disk, a transfer pressing disk, a positioning pin shaft and a compressing bolt, wherein the fixed disk is connected with the transfer pressing disk through the compressing bolt, and the friction twisting-stopping disk is positioned between the fixed disk and the transfer pressing disk; a pin shaft hole is formed in the friction twisting-stopping disk, and the positioning pin shaft is communicated with a pin hole in a part to be tested through the pin shaft hole for positioning; a space formed by the friction twisting-stopping disk, the fixed disk and the transfer pressing disk can accommodate the part to be tested. The invention provides an end face friction twisting-stopping structure which has the advantages of simple structure, convenience in use and easiness in assembly and decomposition, and can realize self-adaptive twisting constrained installation of a shaft end face in any angle in the circumferential direction during assembly, greatly facilitate twisting positioning of a shaft type part in the circumferential direction, reduce the assembly difficulty and shorten a testing period.

Description

technical field [0001] The invention relates to the field of mechanical technology, and more specifically, to a torsion-stop simulation structure device and application of a tapered gear shaft. Background technique [0002] A certain type of tail shaft is a key part of the helicopter transmission system, and it bears complex and diverse loads in actual work. For the test and assessment of shaft parts with conical tooth structure, the usual method of torsion stop is to process the matching conical tooth structure to stop torsion, but this structure cannot be installed at any angle in the circumferential direction for self-adaptive torsion restraint during assembly. Moreover, the assembly and disassembly is difficult, the design and processing cycle is long, and the processing cost is high, which affects the test cycle.
