Abstract

The invention discloses a helical cylindrical gear, and relates to the technical field of gear transmission. The helical cylindrical gear with an anti-backlash device comprises gear pieces; the gear pieces comprise a left gear piece and a right gear piece; nuts are fixedly installed on one side of the left gear piece; a groove is formed in one side, away from the nuts, of the left gear piece; a rubber sleeve is fixedly connected inside the groove; step holes are formed in one side of the right gear piece; and bolts are movably connected inside the stepped holes. According to the helical cylindrical gear with the anti-backlash device, the nuts and the bolts can be effectively embedded in the gear piece through nut holes and the stepped holes on one side of the gear piece, the applicabilityof the anti-backlash helical cylindrical gear is improved, the requirement on a transmission system is reduced, the process attractiveness of the helical cylindrical gear is improved, the bolts adoptinner hexagonal bolt, the gap between the gear pieces is conveniently adjusted, and the stability of gear transmission is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of gear transmission, in particular to a helical cylindrical gear. Background technique

[0002] The gear is a common part often used in mechanical transmission. The gear is made of high-quality high-strength alloy steel, and the surface is carburized and hardened. It has a strong bearing capacity and is durable. In practical applications, helical gears are widely used in high-speed and heavy-duty occasions due to their stable transmission, low impact, vibration and noise. Helical gears are the most commonly used type of automotive power transmission gears. Working under certain conditions and requires less vibration and noise. In order to improve their dynamic performance at high speed and reduce vibration and noise, tooth profile modification has become a necessary design and process means. The meshing of gears and gears has backlash. , will produce a certain amount of backlash and reduce the transmissio...
