Abstract

The invention discloses a detection device for the preload of an elastic preloaded bearing assembly and relates to a preload detection device. According to the invention, the problem that a device for detecting the preload of the elastic preloaded bearing assembly does not exist at present is solved. Two linear guide rails are fixedly arranged on the upper end surface of a lower support plate in a vertical manner, a guide panel and a loading panel are both arranged on the two linear guide rails in a penetrating manner, a screw bearing seat is vertically arranged on the loading panel, the lower end of the screw bearing seat is positioned at a third through hole of the loading panel, a screw bearing is arranged at the upper end of the screw bearing seat, two loading spring guide shafts are vertically and fixedly arranged on the upper end surface of the guide panel, a loading spring is arranged on each loading spring guide shaft in a penetrating manner, two fourth through holes are processed on the loading panel, each loading spring guide shaft is positioned in the corresponding fourth through hole, a force sensor is arranged in the center of the guide panel, and a spherical loading head is arranged at the lower end of the force sensor. The detection device for the preload is used for detecting the preload of the elastic preloaded bearing assembly.

Description

technical field [0001] The invention relates to a device for detecting the pre-tightening force of an elastic pre-tightened bearing assembly. Background technique [0002] Bearing assemblies are critical components of many pieces of equipment and are central to ensuring their proper functioning. How to ensure the normal operation of bearing components in harsh working environments such as large temperature differences is a common concern of many scientific and technological workers. There are two main preloading methods for bearing assemblies, namely, positioning preloading and constant pressure preloading. When working in an environment with large temperature differences and low load-carrying capacity requirements, in order to ensure that the bearing assembly can work safely and reliably, designers often It is realized by the constant pressure preload method, which is what we often call the elastic preload method, and the stiffness of the elastic element is much lower than...
