摘 要:制动器又叫抱闸,是具有使运动部件(或运动机械)减速、停止或保持停止状态等功能的装置,其是通过非旋转元件(与车身或车架相连的部件)及旋转元件(与车轮或转动轴相连的部件)之间的相互摩擦来阻碍其转动或转动的趋势,以此来控制电机的运转以及惯性运转。制动器中磨损最大的机械零件是瓦块摩擦片。制动器在使用期间绝对不允许制动器出现制动故障、失灵的情况,否则极容易造成事故发生。但目前制动器瓦块摩擦片磨损程度全部依靠人员的经验观察,没有自动化报警系统。所以关于制动器瓦块摩擦片自动监测报警器的研究意义重大。

Absrtact: Brake, also known as holding brake, is a device with the function of decelerating, stopping or maintaining the stopping state of moving parts (or moving machinery). Brake pad friction plate is the most worn mechanical part in the brake. The function of the brake is to prevent the rotation or rotation trend of the non rotating components (parts connected with the body or frame) and the rotating components (parts connected with the wheel or the rotating shaft) through mutual friction, so as to control the motor operation and inertia operation. Because of the particularity of the brake, it is absolutely not allowed to have brake failure or failure during the use of the brake, otherwise it is very easy to cause accidents. At present, the wear degree of brake pad friction plate depends on the experience observation of personnel, and there is no automatic alarm system. Therefore, the research, design and application of automatic monitoring alarm for brake pad friction plate are of great significance.
Key words: Brake; Brake pad friction plate; Automatic monitoring alarm for brake pad friction plate
前言
制动器俗称闸、刹车,是具有使运动部件或机械减速、停止运动或保持其停止状态等作用的机械零件。制动器起到制动的原理为通过非旋转元件(与车身或车架相连的部件)及旋转元件(与车轮或转动轴相连的部件)之间的相互摩擦来阻碍车轮转动或车轮转动的趋势。制动器的主要结构有制架、制动件和操纵装置等。一般来说,制动器通常安装于设备的高速轴上,但对于矿井提升机、电梯等对安全性要求较高的大型设备则安装于靠近设备工作部分的低速轴上。而無论安装于何处,制动器瓦块摩擦片都是制动器中磨损最大的机械零件[1-4]、[7]、[8] 。
