Problems solved by technology

[0002] Worm drive is a gear transmission between staggered shafts composed of a worm and a turbine meshing with each other. During the transmission process, the meshing action between the worm and the turbine produces an axial force on the worm. When the load is large, the meshing between the worm and the turbine The pressure and friction between the teeth are also large, which makes the worm wear, resulting in unstable transmission and decreased transmission accuracy, which cannot meet the processing requirements.

Embodiment Construction

[0011] As shown in the figure: the present invention provides a worm, including a left journal 1, a right journal 2 and a shaft head 3, a helical tooth 4 is provided between the left journal 1 and the right journal 2, and the helical tooth 4 is used for The meshing of the worm gear, the oil passage of the lubricating oil inside the transmission friction surface of the helical tooth 2, when the worm moves, the oil inlet 6 of the lubricating oil passage on the non-friction surface of the worm is filled with lubricating oil, passes through the oil passage, and is on the friction surface of the worm. The outlet 7 of the lubricating oil channel allows oil to be injected into the friction surface between the turbine and the worm, so that the friction between the turbine and the worm is reduced and the wear is reduced. The pitch of the worm increases from left to right. During use , when the worm is worn, thin the adjusting gasket, move the worm axis to the left for a certain distance...

Abstract

The invention relates to the technical field of machine tool equipment, in particular to a worm. The worm comprises a left shaft neck, a right shaft neck and a shaft head and is characterized in that helical teeth are arranged between the left shaft neck and the right shaft neck, screw pitches among the helical teeth can be greatly increased from left to right, a lubricating oil duct is arranged in a driving friction surface of the helical teeth, and the shaft head is provided with a key slot. The worm provided by the invention is long in service life, the processing precision and working efficiency of a machine tool can be improved.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a worm. Background technique [0002] Worm drive is a gear transmission between staggered shafts composed of a worm and a turbine meshing with each other. During the transmission process, the meshing action between the worm and the turbine produces an axial force on the worm. When the load is large, the meshing between the worm and the turbine The pressure and friction between the teeth are also large, which makes the worm wear, resulting in unstable transmission and decreased transmission accuracy, which cannot meet the processing requirements. Contents of the invention [0003] In view of the above technical problems, the present invention provides a worm, which can effectively reduce friction due to the lubricating oil passage inside the worm, and because the pitch of the helical teeth gradually increases from left to right, the double-pitch worm can be used on the worm After w...
