Problems solved by technology

[0002] As we all know, when the ball screw pair of the machine tool and the rolling bearing work, if dirt and foreign matter enter, it will wear out quickly, becoming the main cause of damage, and affecting the accuracy of the machine tool. The crawling phenomenon that may occur during the transmission process
Therefore, in order to avoid the entry of foreign matter (such as cutting debris), dust-proof devices must be used, such as: wrinkle protection cover, screw sheath, etc., to completely protect the screw shaft, which increases the cost of the machine tool. and time-consuming machine tool assembly

Abstract

The invention relates to an annular gear ring device belonging to the field of machine tools. The annular gear ring device is provided with a left shell and a right shell, wherein lead screw holes are processed at the middle parts of the left shell and the right shell; three rotating shafts are installed around the lead screw holes, wherein one rotating shaft is an eccentric shaft; two ends of each rotating shaft are respectively fixed on the left shell and the right shell; the three rotating shafts are respectively sleeved with a cylindrical roller; each roller can rotate around each rotating shaft; and an annular gear ring is processed on the outer edge of each roller.

Description

technical field [0001] The invention relates to the field of machine tools, and in particular relates to an annular ring gear device suitable for vertical motion transmission of machine tools. Background technique [0002] As we all know, when the ball screw pair of the machine tool and the rolling bearing work, if dirt and foreign matter enter, it will wear out quickly, which will become the main cause of damage, and affect the accuracy of the machine tool, and crawling may occur during the transmission process. Therefore, in order to avoid the entry of foreign matter (such as cutting debris), dust-proof devices must be used, such as: wrinkle protection cover, screw sheath, etc., to completely protect the screw shaft, which increases the cost of the machine tool. And it takes time to assemble the machine tool. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an annular ring gear device with simple s...
