Description

Technical Field

[0001] The invention belongs to the field of preparation of a marine bearing seat, and in particular relates to a detachable and adjustable marine bearing seat. Background Art

[0002] Bearing is an important component of a lubricated roller bearing seat in contemporary mechanical equipment. Its main function is to support the mechanical rotating body and ensure its rotation accuracy. In the marine field, a variety of transmission shafts are often required for rotational drive, so a large number of bearing seats need to be used. Marine bearing seats generally require high-intensity operations. The transmission shaft is generally fixedly connected with the support ring body on the bearing seat, and then the support ring body is rotatably installed on the bearing seat. The support ring body can be rotatably installed on the seat body of the support seat through a rolling ball. Such long-term high-intensity operation will cause friction between the support ring body and the rolling ball, and friction between the rolling ball and the seat body of the bearing seat. The friction will generate high temperature, resulting in local deformation of the components, so that the service life of the support ring body is not long and needs to be replaced regularly. The existing structural assembly cannot conveniently replace the support ring body. At the same time, the thermal deformation of the support ring body makes the rotation of the transmission shaft unstable, affecting normal operation. For this reason, it is necessary to upgrade and transform the existing structure to reduce structural wear, reduce the disadvantages of high-temperature thermal deformation, and improve the service life of the structure.
