φ3.5×13M闭路水泥磨(传动及进出料部件设计
摘要:球磨机是水泥厂粉磨水泥生料、熟料的主要设备。广泛用于建材、冶金、选矿、电力及化工行业,用于粉磨水泥及其它物料。球磨机具有破碎比大,生产能力大,对物料适应性强,磨损件容易更换等特点。
本课题是Φ3.5×13M闭路水泥磨(传动及进出料部件设计。首先对磨机进行总体计算,得到了球磨机的工作转速和所需要的功率,从而可以进一步进行传动部件的设计,具体有电动机的选择和减速机的选择以及相配套的联轴器的选择。根据传动的要求,不但要合理设计球磨机的传动装置,还要尽可能降低生产成本,节约土地。设计齿轮时,在保证齿轮强度的前提下,采用大齿数和小模数,延长大齿轮的寿命,降低成本,达到最佳经济效益。应用最优化方法布置齿轮,并设计轴的结构,对轴进行强度校核。此外设计了进料装置和出料装置,为了提高进料的能力,进料装置增强了通风能力。
通过对传动和进出料部分的设计,使其达到节能、高效、低噪音、安全可靠的要求。合理的降低了球磨机的制造成本,符合企业的要求,带来较好的经济效益。关键词:球磨机;边缘传动;进/出料装置
The Design of The Transmission Part an d The Inlet/Out Part of theφ3.5×13M Closed-circuit Cement Mill
Abstract:Ball mill is a main equipment of cement plant for pulverizing clinker and raw cement material. It is widely used in building material, metallurgy, selecting ore, power and chemical industry, grinding cement and other material. The features are large crushing and productive capacity, strong suitability and easy to change the abrasive parts etc.
This topic is the design of the transmission part and inlet/out pipe part of φ3.5×13m closed-circuit cement mill . After the computation of the overall ball mill, I got the working power of the ball mill and the working rotary speed. Then I design the driving
device including the choice of the motor and the speed reducer. Also I should choose the model of the couplings which are coordinative composition of the motor and the speed reducer. According to the request of driving device, I not only need to design the driving device in reason and depress the cost of production but also to saving land. While designing the gear wheel, on the premise of guaranteeing the intensity of the gear wheel, the big tooth counting and small modulus is adopted, this can lengthen the life of big gear wheel, lower costs and reach the best economic benefits. Applying and optimizing the method to fix up the gear wheel, the structure of the axle is designed, and the intensity to check the axle is carried on.In addition, I design the inlet/out part. In order to improve the capacity of the feed, feeding device enhanced ventilation capacity.
Energy-conservation, high-efficient, safe and reliable demand with low noise are realized through the design of the transmission part and the inlet/out pipe part. we can bring down the cost of the manufacture of the accessory which is the purpose of many factories so that we can achieve a better economic effectiveness.
Key words: Ball mill; Edged form Transmission; Inlet/out part.
