Embodiment 1

[0316] Embodiment 1: single large negative gear meshing transmission

[0317] The first-gear gear of the 6T53 automobile gearbox, the installation center distance is a=123, and the transmission ratio is required to be i=5. According to the calculation, actually determine the pinion z 1 =9, large gear z 2 =43, modulus m n =5, pressure angle α n =22.5°, helix angle β=8.1272222222° (8°7'38"). Specific gear and hob parameters are shown in Table 1~Table 2:

Abstract

The invention discloses a single and large negative addendum modification involute gear transmission device which comprises a pair of large gear and small gear which are meshed. The working tooth profile of gear teeth of the large gear comprises a first outwards-convex involute part located on the outer portion of the base circle of the gear and further comprises a second inwards-concave involute part located in the base circle of the gear. The upper end of the second involute part is in smooth connection with the lower end of the first involute part at the base circle of the gear. The small gear comprises a third outwards-convex involute part located on a tooth top and a fourth outwards-convex involute part located on a tooth root. The third involute part and the fourth involute part are in smooth connection. The third involute part on the tooth top of the small gear is meshed with the second involute part on a tooth root of the large gear in a convex-concave arc mode. The single and large negative addendum modification involute gear transmission device has the advantages of being long in service life, high in transmission reliability, low in maintaining cost, easy to install and the like.

Description

technical field [0001] The invention relates to the technical field of gear transmission in mechanical transmission, in particular to a single large negative displacement involute gear transmission. Background technique [0002] Mechanical transmission refers to the transmission that uses mechanical means to transmit power and motion. The types of commonly used mechanical transmission systems include gear transmission, worm gear transmission, belt transmission, chain transmission, and wheel train. Among them, gear transmission is the most widely used form of transmission in mechanical transmission. Its transmission is relatively accurate, high in efficiency, compact in structure, reliable in operation and long in life. When the gear is driven, the tooth profiles of the two wheels must meet the following conditions: "No matter where the two tooth profiles are in contact, the common normal line passing through the contact point must pass through the fixed point C on the conne...
