Eddy current crank arm buffer

Abstract

The invention discloses an electric eddy current crank arm buffer, which includes a rocker arm, and a connecting rod is hinged on the rocker arm. A fixed fixed part, the support plate can rotate with the rocker arm about the shaft or axis, a magnet and a conductor, one of the magnet and the conductor is installed on the support plate, and the other of the magnet and the conductor is installed on the On the rocker arm, and the position of the magnet and the conductor is opposite, the rotation of the support plate and the rocker arm about the shaft or the axis can drive the magnet and the conductor to cut the magnetic force line to generate a damping force. The buffer of the invention has a simple and durable structure, obvious buffering effect, no working fluid, no liquid leakage problem, and no power supply for working in a magnetic field. Especially when applied to an electric shovel, it can reduce the maintenance cost of the electric shovel, reduce the failure time of the electric shovel, and create greater economic benefits for mine production.

Description

technical field [0001] The invention relates to the technical field of buffers, in particular to a crank arm type buffer utilizing the eddy current effect. Background technique [0002] Shock absorbers are often used to reduce the impact force caused by vibration between various components. Traditional buffer devices include mechanical and hydraulic. The mechanical buffer needs to adjust the preload of the spring frequently. If it is not adjusted properly, the buffer will be too tight or too loose; while the hydraulic buffer has problems of leakage and sealing. These two types of buffers have high requirements on the structure and materials in contact with each other, and the fatigue strength and durability of the structures and materials are often difficult to meet the requirements, resulting in poor buffering effect of the buffer device and low service life. and high replacement costs. [0003] When the above-mentioned mechanical or hydraulic buffer device is applied to...
