What to do if the spring cone crusher is very noisy

As one of the important equipment for crushing, the spring cone crusher sometimes has the problem of excessive noise during use, which affects the work of the production workers and the normal operation of the equipment. Jiaozuo Zhongxin introduces the noise generation and the noise of the spring cone crusher. Solution.

1. Cause

(1) The installation of large and small bevel gears is the same as the installation of small bevel gears and normal gears, which destroys the correct meshing conditions of a pair of gears and causes additional shock vibration and additional sliding wear during the operation of the gears, resulting in the gears The lifespan is shortened, and even the teeth are hit, causing noise.

(2) The matching clearance between the main shaft and the cone bushing is inappropriate. If the clearance is too large, it will cause instability in operation, causing the cone crusher body to vibrate and produce noise. If the clearance is too small, it is easy to cause a shaft holding event.

(3) The gap between the eccentric shaft sleeve and the frame bushing is too large, causing additional impact load and generating noise.

(4) The unbalanced inertial force and moment of inertia during operation cause shock and vibration, thereby making noise.

(5) The gear processing accuracy is not high, which causes the phenomenon of tooth punching during work and produces noise.

2. Solution

(1) To fundamentally eliminate the noise of the spring cone crusher, it is necessary to correctly mesh the large and small bevel gears to eliminate the reciprocating sliding and additional impact between the gears, prolong the service life of the gears and fundamentally eliminate the source of noise. .

(2) Ensure that the clearance between the main shaft and the cone bushing and the eccentric bushing and the frame bushing is within a reasonable range.

(3) Improve the processing accuracy of the bevel gear of the crusher, ensure the uniform contact surface, extend the service life, and avoid noise.
