Background
The triaxial elliptical vibrating screen is called a triaxial screen for short, and the triaxial screen takes a vibrator as an excitation source. The vibrator consists of three parallel shaft systems, a gear with the speed ratio of 1 is arranged in a box body of the vibrator positioned on the transmission side of the screening machine, an eccentric block with the same eccentric weight and eccentric radius is arranged on each gear assembly, and an eccentric block with the same eccentric mass and eccentric radius is arranged in a box body of the vibrator positioned on the other side of the screening machine. The driven wheel connected with the vibrator is driven by a motor through a triangular belt, and then drives three gears to realize that three shafts rotate at the same speed to generate exciting force, so that the screen box is forced to generate elliptical track vibration.
In order to ensure that a bearing and a gear which are arranged in the vibrator can normally run, lubricating oil needs to be contained in the vibrator box body, so that the two ends of the vibrator are respectively provided with the vibrator box body and the box body cover plate, and the box body can store the lubricating oil and also plays a role of a protective cover.
