Tool for adjusting position of worm gear of worm gear mechanism

Abstract

The invention provides a tool for adjusting the position of a worm gear of a worm gear mechanism. The tool comprises a first outer ring seat, a first inner ring seat, a second outer ring seat and a second inner ring seat; the first outer ring seat and the first inner ring seat are both arranged at the top of a worm gear seat, and the second outer ring seat and the second inner ring seat are both arranged at the bottom of the worm gear seat; the first inner ring seat and the second inner ring seat are both in a circular ring shape; the first outer ring seat is detachably connected with the worm wheel seat and is seated on the top surface of the worm wheel seat; the first inner ring seat is sleeved with the first outer ring seat; the second outer ring seat is detachably connected with the worm wheel seat, and the top surface of the second outer ring seat is in contact with the bottom surface of the worm wheel seat; and the second inner ring seat is sleeved with the second outer ring seat. The contact position is observed by painting the tooth surface of the worm gear, and the axial position of the corresponding first inner ring seat or second inner ring seat is adjusted according to the adjustment requirement, so that the trial and error time is saved, and the optimal positions of the worm gear and a worm can be accurately found.

Description

technical field [0001] The invention relates to the field of mechanical assembly, in particular to a tool for adjusting the position of a worm wheel of a worm gear mechanism. Background technique [0002] Aerospace products use the self-locking feature of the worm gear mechanism to prevent the displacement of moving parts due to the huge vibration generated during launch. In order to meet the harsh environmental requirements of aerospace products, the relative position of the worm gear and the worm has very strict requirements. In the past, adjusting the position of the worm gear relative to the worm required constant trimming figure 1 The shown two bearing caps located at the top and bottom of the worm gear mechanism are time-consuming, labor-intensive and labor-intensive to try a little bit. For this reason, a frock that can adjust the position of the worm gear at the same time is designed. Contents of the invention [0003] In order to solve the above problems, the p...
