Problems solved by technology

This scheme mainly uses the timing relationship between the keyway on the gear and the intermediate shaft to solve the problem of timing alignment of spur gears during press-fitting, but this gear alignment device cannot solve the problem of timing alignment of helical teeth. When the helical gears are pressed against each other, it is necessary for the tooth slots of each gear to ensure a certain angular positioning relationship.

Abstract

The invention discloses an AMT gearbox middle shaft assembly helical tooth aligning mechanism, a press fitting device and a press fitting method, and relates to the technical field of AMT gearbox gear press fitting. The AMT gearbox middle shaft assembly helical tooth aligning mechanism comprises a positioning seat and a tooth aligning assembly, wherein a mounting hole is formed in the positioning seat; and the tooth aligning assembly comprises a bushing, a driving part, a connecting rod and a positioning pin, the bushing is mounted in the mounting hole in a matched manner, the driving part is fixedly arranged on the bushing or the positioning seat, the connecting rod and the positioning pin are movably arranged in the bushing, the connecting rod is connected with the driving part and the positioning pin, and the positioning pin can be driven by the driving part to move and abut against the interior of a tooth groove of a helical tooth gear set. Angular positioning can be conducted on the helical tooth gear set, the press-fitting precision of the helical tooth gear set is ensured, and the connecting rod and the positioning pin can be protected and guided.

Description

technical field [0001] The invention relates to the technical field of press-fitting gears of AMT gearboxes, in particular to a helical tooth-to-gear mechanism, a press-fitting device and a press-fitting method of an AMT gearbox central shaft assembly. Background technique [0002] AMT (Automated Mechanical Transmission, mechanical automatic transmission) transmission center shaft assembly is equipped with multiple gears to ensure power transmission. When pressing the gears of the intermediate shaft assembly of the AMT transmission to the intermediate shaft parts, it is necessary to ensure both the press-fitting accuracy and the timing accuracy of the teeth. [0003] The existing gear aligning device includes a workbench, a positioning column arranged on the workbench for fixing the overall position of the pinion, a first tooth positioning mechanism for positioning the position of the pinion teeth by supporting the tooth groove of the pinion, and a set The positioning frame...
