Embodiment Construction

[0024] Embodiments according to the present invention will now be described in detail with reference to the accompanying drawings, examples of which are shown in which like reference numerals refer to like components throughout.

[0025] figure 1 A typical shafting configuration is shown.

[0026] Such as figure 1 As shown, the shafting structure includes an inner shaft 10 , an outer shaft 20 and a first bearing 30 . The outer shaft 20 can be a hollow shaft, and is sleeved on the inner shaft 10. The first bearing 30 can be arranged between the inner shaft 10 and the outer shaft 20 for realizing relative rotation between the inner shaft 10 and the outer shaft 20.

[0027] In addition, the shafting structure may further include a second bearing 40, and the first bearing 30 and the second bearing 40 may be arranged at intervals along the axial direction of the inner shaft 10, so as to make the inner shaft 10 and the outer shaft 20 cooperate more stably. Optionally, the first ...

Abstract

The invention provides a shafting structure and a mounting method thereof. The shafting structure comprises an inner shaft, an outer shaft, a first bearing and a sensor, and the outer shaft is a hollow shaft and sleeves the inner shaft; the first bearing is arranged between the inner shaft and the outer shaft; and the sensor is mounted in the outer shaft and used for measuring the distance value between the inner ring and the outer ring of the first bearing when the first bearing is mounted so as to determine the pre-tightening force of the first bearing based on the distance value. According to the shafting structure, the pre-tightening force of the first bearing can be accurately controlled, so that the rigidity of the first bearing can be improved, the service life of the first bearing can be prolonged, and the reliability of the shafting structure can be ensured.

Description

technical field [0001] The invention relates to the technical field of shafting, in particular to a shafting structure and an installation method thereof. Background technique [0002] The shafting structure is widely used in modern industry, and the installation process of the bearing as the core component of the shafting structure is directly related to the safe operation of the shafting structure. Bearings require different preloads during assembly according to different applications. [0003] The preload of the bearing has a very important influence on the life and rigidity of the bearing. Therefore, during the assembly process of the shafting structure, the control of the preloading force is of great significance to the reliability of the shafting structure. However, the current installation method cannot accurately determine the size of the preload in the actual assembly process, so it is difficult to ensure the reliability of the shafting structure. Contents of the...
