Abstract

The invention relates to an axial load and rotary load loaded loading device. The loading device comprises a cylinder, the cylinder comprises a hollow cylinder body and an axial loading plunger in sliding fit with the cylinder body, the axial loading plunger is assembled with a rotating shaft by relative positioning during loading, one end of the rotating shaft is in transmission connection with arotating motor, and the other end of the rotating shaft can output rotary load and axial load. The rotating shaft drives the rotating shaft to rotate to realize rotary loading, the cylinder plunger transmits the axial load to the rotating shaft to realize axial loading, the rotating motor can realize stepless rotary load loading, and the cylinder can realize stepless axial load loading; and compared with a traditional manual loading manner, the device is characterized by high precision and capability of loading high axial load and high rotary load.

Description

technical field [0001] The invention relates to a loading device integrating axial load loading and rotational load loading. Background technique [0002] In modern industry, the measurement equipment for bearing protrusion, bearing axial stiffness and paired bearing pretightening force mostly adopts single-acting air spindle loading system. This type of loading system has high axial loading accuracy, high rotation accuracy, and stepless Loading, and a certain amount of stroke is required during the shafting loading process. However, the single-acting air spindle loading system is generally manually driven due to the mechanical structure. Not only the spindle rotation speed is low, but also the labor intensity of the operator is increased, and the manual drive will also bring measurement errors. With the improvement of the automation level of instruments and equipment and the dynamic speed requirements of the spindle, this type of manual drive single-acting air spindle load...
