Vibration reduction adjustment method for single-cylinder cone crusher based on stepless adjustment of eccentric block

Abstract

The invention discloses a single-cylinder cone crusher vibration reduction adjustment method based on the stepless adjustment of the eccentric block. An adjustable eccentric block is installed on the eccentric assembly, and the eccentric force of the main shaft assembly is balanced by adjusting the position of the eccentric block. The thin edge of the upper end face of the eccentric copper sleeve and the eccentric steel sleeve is processed with the scale of the eccentric copper sleeve and the scale of the eccentric steel sleeve pointing to the center of the circle. An included angle will be formed, and the center line of the included angle points to the eccentric direction of the equipment itself. According to the included angle, the specific installation position of the eccentric block can be determined to ensure that the eccentric force generated by the eccentric block and the eccentric force generated by the main shaft assembly are collinear and reverse , to achieve the best damping effect. The invention balances the eccentric force of the main shaft assembly by adjusting the eccentric block, thereby weakening the vibration of the equipment itself, thereby reducing the damage of the equipment to components such as the installation foundation, the motor, and external pipes, and improving the utilization rate of energy.

Description

technical field [0001] The invention relates to the technical field of single-cylinder cone crushers, in particular to a vibration reduction adjustment method for single-cylinder cone crushers based on stepless adjustment of eccentric blocks. Background technique [0002] The single-cylinder hydraulic cone crusher can be widely used in various industrial fields such as black, non-ferrous, non-metallic mines and sand and gravel. The characteristics of large crushing force, high production efficiency, laminated crushing, uniform grain shape of the finished product, less consumption of consumable parts, and low operating cost make the single-cylinder hydraulic cone crusher play an indispensable role in the crushing industry. The principle is that a pair of meshing gears drive the eccentric assembly to rotate, and the main shaft assembly performs a pendulum motion driven by the eccentric assembly to squeeze and crush the materials in the crushing chamber. [0003] It is precise...

Problems solved by technology

This solution is only applicable to the structure of the inherent design of the inertial cone. The principle and structure of the single-cylinder hydraulic cone crusher are different from it. There is no fixed eccentric block to generate vibration, and the installation direction of the transmission shaft is parallel to the vibration direction, so it cannot be implemented. scheme, the adjustment of the counterweight direction is more complicated and inconvenient

[0006] "Cone Crusher" 200420085121.2 mentions the purpose of installing a counterweight on the large gear frame to increase the eccentric force, but it also increases the vibration amplitude of the equipment itself and improves the crushing effect, but it has an adverse effect on the overall stability of the equipment.
