Embodiment approach

[0045]For the two meshing sides of the optically repaired worm bar in step S3, only the two meshing sides are optically repaired, and the middle section of the worm bar with the most serious wear is lightly repaired first, so that the dimensions between the teeth of all the worm bars are kept consistent. In an optional implementation mode here, for the optical repair operation of the worm bar, for example but not limited to the optical repair method disclosed in the publication number CN202010796U can be used. This embodiment adopts the scheme of directly performing light repair on the worm bar, which reduces the process of roughly matching and scraping the old worm bar in the prior art, which greatly reduces the labor of the repair fitter and shortens the repair period.

[0046] More specifically, the distribution of the worm in step S4 includes:

Abstract

The invention discloses a repairing method suitable for a worm and gear pair of a heavy machine tool. The repairing method comprises the steps of S1, measuring engagement side gaps of a gear pair; S2,disassembling gears from a workbench, and numbering the different gear strips; S3, polishing the two meshing sides of the gears; S4, carry out finish turning on worms; and S5, carrying out fine scraping of the gears. The repairing method can eliminate the engagement side gaps between the worms and gears and reduce the probability that the crawling phenomenon occurs when the workbench of the machine tool moves at low speed.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment repair, in particular to a repair method suitable for a heavy-duty machine tool worm screw pair. Background technique [0002] When repairing various heavy-duty machine tools such as heavy-duty gantry milling machines, high-speed milling machines, face milling machines, horizontal boring machines, floor boring machines, etc., the mechanism of worm and worm bar transmission is often encountered. Creeping occurs when feeding. The reason for the low-speed crawling of the machine tool is that in addition to the friction coefficient between the electrical and guide rail pairs and the rigidity of the transmission mechanism, the excessive backlash between the worm and the worm bar is one of the main reasons for the low-speed crawling of the machine tool. [0003] figure 1 The workbench of a heavy-duty gantry milling machine is shown, which is driven by a worm screw and a female bar. figu...
