Description

Technical Field

[0001] The invention relates to the field of gear maintenance equipment, in particular to a gear maintenance device for machine tool accessories. Background Art

[0002] A gear tooth is a raised part on a gear that is used for meshing. Generally speaking, these raised parts are arranged radially. The gear teeth on the mating gears contact each other, resulting in the continuous meshing of the gears. The movement of a pair of reducer gears is completed by the meshing movement of the tooth surfaces. The relative movement of a pair of meshing tooth surfaces includes rolling and sliding. For gears that transmit power, it is necessary to study the force and deformation of the gears. It is necessary to apply mechanical knowledge. There is lubricating oil between the two tooth surfaces of the gear, which involves the knowledge of fluid mechanics. If the surface film generated by the interaction between the lubricant and the gear surface is studied, physical and chemical knowledge is required. Therefore, under the condition of lubricant, the presence of lubricant must be considered to truly and comprehensively reflect the kinematics and dynamics of gear transmission. When the existing gear maintenance equipment fills the gear with lubricant, the original oil stains on the gear adhere to the dead angle of the gear teeth and are difficult to clean. After the new lubricant is injected, the old oil stains will cause different parts of the gear to wear differently, thereby accelerating the wear of the gear. Summary of the invention
