Single-cylinder cone crusher vibration reduction adjusting method based on eccentric block stepless adjustment

Abstract

The invention discloses a single-cylinder cone crusher vibration reduction adjusting method based on eccentric block stepless adjustment. An adjustable eccentric block is installed on an eccentric assembly, and the eccentric force of a main shaft assembly is balanced by adjusting the position of the eccentric block. Eccentric copper bush scales and eccentric steel bush scales pointing to the circle center are machined on the thin edges of the upper end faces of an eccentric copper bush and an eccentric steel bush, when the eccentric copper bush and the eccentric steel bush are combined at different angles, the eccentric copper bush scales and the eccentric steel bush scales can form an included angle, and the center line of the included angle points to the eccentric direction of equipment. The specific installation position of the eccentric block can be determined according to the included angle, it is guaranteed that eccentric force generated by the eccentric block and eccentric force generated by the main shaft assembly are collinear and reverse, and the optimal vibration reduction effect is achieved. According to the single-cylinder cone crusher vibration reduction adjusting method, the eccentric force of the main shaft assembly can be balanced by adjusting the eccentric block to weaken the vibration of the equipment, so that the damage of the equipment to parts such as a mounting foundation, a motor and an external pipeline is reduced, and the utilization rate of energy is increased.

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.
