Gear set for gearboxes

Abstract

The invention discloses a gear set for gearboxes with an aim to provided the gear set capable of improving transmission stability, good in gear lubrication effect and capable of effectively solving the problem that serve life of a gear is affected due to poor gear lubrication effect. The gear set comprises a bushing, a first gear and a second gear, the first gear and the second gear are arranged on the bushing, at least two circumferentially evenly distributed oil storage tanks and oil guiding grooves are arranged in the end face, located in the position facing the second gear, of the first gear, the oil storage tanks are close to the root circle of the first gear, the oil guiding grooves are located between the bushing and the oil storage tanks, and the oil guiding grooves radially extend along the first gear with one end communicated with the oil storage tanks; oil lubrication grooves are arranged on bottom surfaces of at least two toothed grooves in the second gear, at least two circumferentially evenly distributed axial connecting grooves are arranged on the outer side face of the bushing, the axial connecting grooves axially extend along the bushing, and one ends of the axial connecting grooves are communicated with the oil guiding grooves while the other ends are communicated with the oil lubrication grooves.

Description

technical field [0001] The invention relates to the field of gearboxes, in particular to a gear set for a gearbox. Background technique [0002] The speed changer is also called the gearbox, which is a gear transmission device that can change the transmission ratio of the output shaft and the input shaft by fixing or stepping. The speed changer is composed of a transmission mechanism and a speed change mechanism, which can be made into a separate speed change mechanism or combined with the transmission mechanism in the same housing. The lubrication effect of existing gearbox gears is usually splash lubrication, that is, during the transmission process of the gearbox gear train, a part of the gears in the gear train will shake up the lubricating oil at the bottom of the gearbox through rotation, so as to realize the speed change. Lubrication of box gear trains. The current splash lubrication method used in the gearbox, because the gears with smaller diameters in the gear tr...

AI Technical Summary

Problems solved by technology

The current splash lubrication method used in the gearbox, because the gears with smaller diameters in the gear train cannot directly contact the lubricating oil at the bottom of the gearbox, and most of these small gears are located inside the gear train (hidden in the large gear), making splashing It is difficult to meet the lubrication effect of these small gears very effectively, resulting in the problem of poor lubrication effect of some gears in the gear train, which affects the service life of the gears

In addition, in the existing gearboxes, the gears that play a transmission role are usually set separately, and the gears that play the same transmission role are usually assembled on the drive shaft separately, which makes it easier for the gears on the same drive shaft during the transmission process of the gearbox. Misalignment occurs, reducing transmission stability
