Embodiment Construction

[0014] A preferred embodiment of the adjustment method of the present invention involves two sets of meshing gear pairs, including gear one 3, gear shaft one 4, gear two or adjusting gear 6, gear shaft two 8, gear three 11, and gear shaft three 12; A gear box divided into two parts, including gear box 1 and gear box 2 9; a gasket to ensure sealing: gasket 5; 2 adjustment tools, tool 1 13, tool 2 15; several bolts.

[0015] The dimensional tolerance of the upper and lower bottom surfaces of gear box 1 is t 1 , the dimensional tolerance t of the upper and lower bottom surfaces of the gearbox II 9 2 , the dimensional tolerance of gasket 5 is t 3 , when the temperature rises, the thermal expansion of the gearbox is h 1 , the thermal expansion of the gear is h 2 . The gear backlash is c

[0016] Δs=(t 1 +t 2 +t 3 + h 1 + h 2 )×inv-c

[0017] When Δs>0, the noise of the gear increases significantly

[0018] When Δs<0, the oil film cannot be formed between the gear pairs,...

Abstract

The invention relates to a method for adjusting a plurality of gears to be meshed accurately, comprising the following steps: a gear I (3) and a gear III (11) are respectively fixed on a gear box I (1) and a gear box II (9); an adjusting gear (6) is arranged on the gear box II (9), and the position can be adjusted; a tool I (13) is used for detecting center distance between the gear III (11) and the adjusting gear (6), a tool II (15) is used for detecting the center distance between the gear I (3) and the adjusting gear (6); the position of the adjusting gear (6) is adjusted to lead the centerdistance between the gear III (11) and the adjusting gear (6) and the center distance between the gear I (3) and the adjusting gear (6) to be in accordance with the design requirements; the adjustinggear (6) is fixed, so as to lead the gear I (3) and the gear III (11) to be accurately meshed with the adjusting gear (6) respectively. The method has god effect, simple structure, low cost and easyrealization.

Description

technical field [0001] The invention relates to a method for adjusting the precise meshing of a plurality of gears. Background technique [0002] At present, in the field of gear transmission, many gears are assembled on different gearboxes. In order to solve the cost, different gearboxes use different materials. The gears are installed on different gearboxes. When different parts of the gearboxes are processed and assembled separately, there must be tolerances. These tolerances accumulate together, making the backlash of the meshing gears installed on different gearboxes uneven. If the temperature of the operating environment changes greatly and the material expansion rate is different, the tolerance will be further increased, resulting in too large or too small backlash, and even gear interference. These phenomena lead to gear noise, shortened life, or even failure to assemble. This requires very high machining accuracy of the gear seat, and is not conducive to disassemb...
