摘　　要：结合盘式制动器的结构和工作原理,研究不同闸间隙下碟簧厚度增加时盘式制动器制动力矩大小。结果表明:闸间隙为2 mm和1.5 mm时,制动器产生的制动力矩与实际提升最大载荷旋转力矩之比小于3,无法满足安全规程要求。研究碟簧厚度增加对盘式制动器制动力矩的影响,为研究和解决矿井提升机盘式制动器的故障提供了一种新思路。In combination with the structure and the working principle of the disk brake, the paper studied the magnitude of the braking torque of the disk brake at various brake gap while the thickness of the disk spring increasing. Results showed： while the braking gap being 2 mm and 1.5 mm, the ratio of the braking torque of the disk brake to actual rotary torque on hoisting maximum load was less than 3, which failed to satisfy the requirements of the safety specification. The research on the influence of increase in the thickness of the disk spring on the braking torque of the disk brake offered a new thinking for the study and solution of the fault of the disk brake of the mine hoist.
