Parallel twin-screw gearboxes have improved load carrying capacity
Aug 11, 2018

Previous parallel twin-screw gearboxes were designed with a single drive, that is, the front output shaft transmits power to the second output shaft through a pair of gear pairs. However, due to structural reasons such as small center-to-center distance of the two-axle gearbox, large bearing span, and poor rigidity of the shaft, the strength of the pair of gears between the two shafts is lacking, which cannot meet the high-torque flat double extrusion. The use of the unit requires, and the load capacity of the gearbox is reduced, reducing production efficiency.

 

In order to improve this problem, a new type of parallel twin-screw gearbox has been introduced, which is not only simple in structure, convenient in use, but also effectively improves the bearing capacity of the gearbox. The casing of the parallel twin-screw gearbox is composed of an upper casing and a lower casing of a separate structure of the upper and lower casings, the lower casing is fixed with an input shaft, the upper casing is provided with a transition shaft, and the transition shaft passes through the gear and the input shaft. Engagement connection.

 

At the same time, at both ends of the parallel twin-screw gearbox transition shaft, there are respectively a front slanting helical gear and a second slanting helical gear, and under the same central distance, the carrying power is doubled compared with the ordinary flat double gearbox. The above meets the requirements for the use of high-torque, high-efficiency flat double extrusion units.

 

Because the parallel twin-screw gearbox adopts the special involute profile of the point line meshing, the tooth surface contact fatigue strength and the root bending strength are both improved compared with the conventional involute gear. The power splitting technology is adopted. In order to solve the problem of the uniform load of the two pairs of gear pairs, the helical gear is generated when the helical gear is driven. Under the action of the axial force, the meshing gap can be automatically adjusted to achieve the uniform load effect.
