A jig for aligning teeth of double countershaft transmission with fine and high teeth

Abstract

The invention discloses a tooth aligning clamp of a twin countershaft transmission with thin and high teeth. The tooth aligning clamp comprises a locating plate (1). A countershaft locating hole (101) for assisting in mounting a countershaft is formed in the center of the locating plate (1). Through holes are formed in the two sides of the countershaft locating hole (101) respectively. Each through hole is provided with a locating sleeve (2). Intermediate shaft locating holes (201) for assisting in mounting intermediate shafts are formed in the centers of the locating sleeves (2) respectively. The locating sleeves are in clearance fit with intermediate shaft bearing pedestals and the locating plate, and after the teeth are aligned, the intermediate shaft locating holes in the locating sleeves are used for fixing a left intermediate shaft assembly and a right intermediate shaft assembly. If the intermediate shaft bearing pedestals cannot be smoothly sleeved with the locating sleeves, problems happen in the tooth aligning process. The transmission with wrong tooth aligning is prevented from continuing to be assembled, and therefore the aim of preventing mistakes is achieved, and the one-time boxing yield is improved.

Description

[0001] Technical field: [0002] The invention relates to a clamp for a transmission, in particular to a gear pairing clamp for a double intermediate shaft transmission with fine and high teeth. [0003] Background technique: [0004] In the domestic gear industry, there are more and more fine-tooth tooth designs for transmissions. Most of the double-countershaft transmissions of a company use coarse-tooth designs except for the 6DS series. Coarse-tooth designed transmissions are easy to put into the box and aligned, and it is not easy to deviate after the alignment is completed. If the alignment deviates, the front end bearings of the left and right intermediate shafts will not be able to be assembled, so the alignment error can be found in time. The two-shaft assembly of the transmission with fine and high teeth of the full synchronizer is a high and low undulating sawtooth structure. It is difficult to enter the box. Assembly can be done without being detected. [0005] Th...

AI Technical Summary

Problems solved by technology

[0005] The 6DS series transmission is designed with thin and high teeth. The transmission gear at the front end of the intermediate shaft and the first shaft gear have a small modulus, so the pitch between the teeth is smaller. When the shaft rear bearing vibrates, it is easy to make the teeth deviate and it is not easy to find, resulting in wrong teeth alignment and rework

The transmission gear at the front end of the intermediate shaft of the 6DS series transmission and the one-axis gear have a small modulus, so the tooth spacing is smaller, and mistakes are prone to occur during the alignment process and the alignment marks are wrong, resulting in misalignment.
