What Drives The Eccentric Sleeve

The eccentric sleeve is vice driven by the transmission shaft and bevel gear

, the inner bore is supported by the main shaft. The outer cylinder drives the moving cone to do swing motion. And the moving cone is driven by the motor via V belt or the hydraulic coupling. Theres sliding bearing inside and outside the surface of the eccentric sleeve. Furthermore, the space between the moving cone and the chassis is labyrinth seal brimmed with dry oil, the up and down is regulated by the hand wheel through the lower bevel gear. The vertical position of the moving cone and the width of the discharge port is read by the needle and dial.

In our country, the spiral plate crusher has achieved great success as a superfine crushing method in the gold processing plant. But it is to be practiced in the field of iron ore. At present, the largest middle fine crushing cone crusher is only 120in, viz. the Simon cone crusher and the 3000 series cone crusher of the former Soviet Union. Those crushers are manufactured on the basis of enlarging the original size, but theres no big difference between the basic principle and its main structure. And some changes occur in the eccentric parts of the cone crusher. The face of the main shaft is drum-shaped, adopting a sphere matching with the corresponding bore of the bush. Thus, the matching gap has been reduced and the arm of the crushing force has been increased which has improved the loading conditions of the main shaft and the eccentric sleeve.

Whats more, the precession angle of the crusher has been reduced from 2 degree to 1.6 degree and 1.5 degree. The swing times of the moving cone ought to be increased accordingly. The promotion of the swing times can augment the crushing force and decrease the gap of the eccentric parts. The transformation of the crushers structure is as follows: the crushing chamber is formed between the moving cone liners. The static cone is fixed in the upper bracket while the moving cone is supported in the shaft of the balls surface. Theres a set of ring springs under the shaft bracket of the ball surface, the spring is installed within the main shaft. The lower part of the main shaft is fastened in the lower bracket and the upper matches with the eccentric sleeve.
