Description

Technical Field

[0001] The invention belongs to the technical field of screw supports, and in particular relates to a novel screw support device. Background Art

[0002] Traditional CNC machine tool screw feed shafts mostly use multiple sets of ordinary angular contact ball bearings or a combination of deep groove ball bearings and thrust ball bearings. However, when applied to high-speed machine tools, this type of configuration has the problems of poor axial resistance, difficulty in controlling axial preload, and insufficient support rigidity of the screw. After searching, the application number "CN202210059245.6" discloses "a screw support bearing assembly", which records that "a disc spring is used to load the screw bearing, which can ensure that the bearing operates normally under a reasonable preload and a suitable external load profile. This load is also applied to the screw at the same time, ensuring that the screw is always in a straightened state, which not only ensures the service life of the bearing, but also makes the slide driven by the screw have a higher position." However, the above comparative documents still have the following problems in actual use:

[0003] In actual use, it is inconvenient to add lubricating oil to the bearings, resulting in inconvenient lubrication, and the support point cannot be adjusted during use, resulting in the problem of ineffective load dispersion.

[0004] Based on this, it is extremely practical to provide a device that can quickly and stably add lubricating oil, facilitate lubrication, and has the function of adjusting the support point. Summary of the Invention

[0005] The purpose of the present invention is to provide a new type of screw support device to solve the above technical problems.
