Abstract

The invention discloses a rolling body for a rolling bearing and the rolling bearing. The rolling body is provided with the shape of cylindrical or conical, a containing hole is formed in the cylindrical end face of the rolling body, and a strain measuring device is arranged in the containing hole for measuring internal stress of the rolling body. According to the rolling body for the rolling bearing, the strain measuring device comprises a strain sensor, a clamping device, an energy collecting device and a signal receiving and transmitting module; the strain sensor is used for measuring stress of the rolling body, the clamping device is used for fixing the strain sensor in the containing hole, the energy collecting module is used for providing energy for the strain measuring device, the signal receiving and transmitting module is connected with the strain sensor in a signal mode, and the measuring result of the strain sensor is transmitted to a calculating unit, so that the bearing play is deduced according to the stress of the rolling body, and therefore, the working state of the bearing is judged, a bearing play adjustment unit is controlled for carrying out real-time adjustment, so that the bearing works in the optimal state, and the service life of the bearing is prolonged.

Description

technical field

[0001] The invention relates to a rolling body for a rolling bearing, said rolling body having a cylindrical or conical shape, wherein a strain measuring device is arranged in the end face of the rolling body, with which strain measuring device the rolling body can be measured stress changes. Furthermore, the invention relates to a rolling bearing having such rolling bodies. Background technique

[0002] It is known from the prior art that rolling bearings can be equipped with sensors in order to measure influencing factors acting on rolling bearings, such as rotational speed or temperature, for example. A bearing device with a wireless sensor is known from CN 1853207 A. The wireless sensor is arranged next to the rolling body to test parameters such as temperature, vibration and rotational speed of the rolling body.

[0003] When rolling bearings work, bearing clearance is a very important parameter. Bearing clearance refers to the amount of movement when...
