球磨机小齿轮轴承座振动的原因分析（Vibration analysis of pinion bearing housing of ball mill）

球磨机小齿轮轴承座振动的原因分析（Vibration analysis of pinion bearing housing of ball mill） Vibration analysis of pinion bearing housing of ball mill [Chinese cement network] author: cement process network unit: Chinese cement net [2011-02-14] Ball mill is the most widely used grinding machine in the fields of heavy industry, such as power generation, ore dressing, chemical industry and building materials. It can grind all kinds of hardness materials, and finally meet the requirements of process specifications. The ball mill of our unit is mainly used for slurry preparation, because it is the core equipment of the enterprise, so it requires a higher rate of operation. Vibration of small gear bearing seat of ball mill is a kind of equipment malfunction that affects normal operation of ball mill. The cause of low frequency vibration are many, and their reasons for the vibration caused by the size, the harm is also not the same, repair of a variety of methods, so we must first find out the main causes of vibration, the method of solving the main contradiction. The common node is the cause and treatment of vibration analysis of transmission structure of mill pinion bearing ball. 1 vibration of pinion bearing housing caused by unbalance (1) the position of the gear (small, big) hole is defective. (2) eccentric inner diameter of gear shaft. (3) the gear material is defective and trachoma occurs. (4) partial wear of gears. (5) the gear drive in the simplified ball and material bonding, cause imbalance. The above imbalance, although the ratio of rotating equipment appears high, but the actual work imbalance, the ball mill pinion bearing seat vibration is not very big. 2 coupling assembly vibration caused by different shafts There are 3 kinds of couplings in the shaft assembly: the two axis center line has radial displacement; the two shafts and the center line twist; the two axle center lines simultaneously offset and measure the axial and radial clearance of the coupling. Excessive deviat
