Design of a Hydraulic Pump of Tractor for Manufacturing with 3D printer Technology

Abstract

In this work, a couple of spur gears design was changed by two double- helical gears design with maintaining other parts in the same size approximately for a hydraulic pump of agricultural tractor. The main purpose of this attempt was to obtain a new hydraulic pump with better specifications and performance. The new elements of the pump were designed using 3D Solid Works software then the stresses analyses and CFD analyses were archived using ANSYS software. The results showed a better flow rate of the hydraulic fluid by about 17%.  This reflects the success of this idea where the flow rate of the new design was much higher compared with spur gear pump. This will conclude that the new design led to improve the pump performance. Moreover, the new pump overcomes the problems that usually appear in spur gears such as noise, vibration fracture. However, this design considers one of the most difficult parts in manufacture process therefor, it was recommended to fabricate it with3D printers
