Embodiment Construction

[0011] In the figure, the helical gear combined gear (1) is installed on the gear central shaft (2), the keyway is machined on the gear central shaft (2), and the center holes of each gear in the helical gear combined gear (1) are machined respectively. The positioning keyway, the helical gear combination gear (1) is connected together with the gear central shaft (2) through the inner positioning key (3), and the shaft shoulder (4) acts as a limit to the helical gear combination gear (1). Gear Combination Gear (1) has two combinations, the first is left-handed helical gear (5) and right-handed helical gear (6) are divided into two groups, and then these two groups of helical gears are arranged opposite to each other and assembled on the gear central axis (2 ), the second is that the left-handed helical gear (5) and the right-handed helical gear (6) are combined into a pair in units of two, and then arranged and assembled on the gear central shaft (2).

Abstract

The invention provides a bevel gear combination in an integral structure, and the bevel gear combination is formed by a plurality of cylindrical bevel gears with same modulus and number of teeth. A plurality of cylindrical bevel gears are divided into two groups of left-hand and right-hand, and the two groups of the bevel gears are oppositely arrayed and assembled onto a shaft to form the structural bevel gear combination. Or, after a plurality of cylindrical bevel gears are divided into two groups of left-hand and right-hand, two cylindrical bevel gears are oppositely assembled into a pair according to the left-hand and right-hand, and a plurality of pairs of bevel gears are symmetrically assembled onto a shaft to form the structural bevel gear combination.

Description

1. Technical field [0001] The invention and a plurality of cylindrical helical gears with the same module and the same number of teeth are combined into an integral structural helical gear combination gear, which belongs to the field of mechanical manufacturing. 2. Background technology [0002] At present, the known cylindrical gears include straight teeth, helical teeth, and herringbone teeth. The load of the spur gear is concentrated, and the transmission is not stable. The load distribution of the helical gear is relatively uniform, the transmission is stable, and the bearing capacity is high, but there is an axial force during transmission. , In order to eliminate the axial force, the herringbone gear is used, but the processing of the herringbone gear is more difficult and the precision is lower. 3. Contents of the invention [0003] In order to overcome the shortcomings and shortcomings of the existing cylindrical spur gears, cylindrical helical gears, and herringbo...
