低噪声持久型云石机设计
摘要
本选题的灵感是来自于市场上云石机存在明显不足之处，针对它们的缺点进行改造。此次的设计改造将使原有的云石机提高效率，增长寿命，最重要的是消除它的大部分噪声。利用改变驱动方式，去除齿轮提高效率，消除噪声，以及将碳刷电机改用无刷电机，增加电动机效率，提高寿命，降低噪声。新型云石机内部构造和传动原理都很简单，内部就只有一个无刷电机，直接对刀片进行驱动。本课题的主要问题有无刷电机直驱所需要的扭矩的计算以及电机的选用，去除齿轮传动后轴心位置如何向下移动使得刀片能够对一定厚度的石材进行切割。通过SW三维软件绘制三维图，对定子位置形状进行分析，确定改造方案，并绘制总装图和必要零部件。

Low noise of persistent marble machine design
Abstract
  The inspiration of this paper is from the marble machine on the market exists obvious deficiency, for their shortcomings. The renovation design will make the original marble machine to improve efficiency, increase longevity, the most important is to eliminate the noise. Use change drive way, remove the gear to improve efficiency, eliminate noise, and will use brushless motor carbon brush motor, increase the efficiency of motor, increase longevity, reduce noise. New type of marble machine internal structure and transmission principle is very simple, within only a brushless motor, directly to drive the blades. This topic the main problem for motor direct driving the required torque calculation and the choice of motor, after removal of gear transmission axis position how to move down the blade can be used to cut stone with a certain thickness. Through SW 3 d software rendering 3 d map, the position of the stator shape were analyzed, and the retrofit scheme is determined, and draw the assembly diagram and the necessary components.
