Abstract
The utility model provides an axial quantitative loading device of a rotary machine. The axial quantitative loading device of the rotary machine is mainly composed of three main parts of a quantitative loading mechanism, a load transmitting and direction keeping mechanism and a lubricating and sealing device. The axial quantitative loading device of the rotary machine is an experimental device exerting quantitative axial load on the rotary machine. A loading rod rotates to move relatively to a support in an axial and spiral manner. An end part of the loading rod extrudes a measuring cell, so that the axial load is produced. The size of the load is measured through the measuring cell. The measuring cell is fixed on an end cover. The load is finally transmitted to a load carrying shaft through the end cover and a bearing. The sealing of the bearing is realized through the common effect of the end cover and a shaft retainer up and the lubrication of the bearing is realized through an oiler. The axial quantitative loading device of the rotary machine provided by the utility model is wide in application range and can be used for realizing axial load carrying simulation of the large-size rotary machine. The axial quantitative loading device of the rotary machine is simple in structure, convenient to operate, comparatively accurate in measurement and comparatively convenient in installation.
