摘　　要：针对外抱带式齿形制动器在工作过程中出现的非全齿啮合工况,分析非全齿啮合产生的原因及出现概率。为降低非全齿啮合工况对制动器的不良影响,提出了一种浮动齿形的外抱带式方案,并基于该方案分析制动过程中全齿啮合与非全齿啮合工况下制动器的工作特性,以及不同非全齿啮合角度对制动器工作参数的影响。结果表明:非全齿啮合工况下的制动时间略短,但啮合后的制动鼓转速较高,进而导致碰撞时更大的冲击力矩,因此应避免非全齿啮合工况的发生。In this article,the analysis is conducted on the causes and probability of non-full-tooth meshing during the operation of the tooth band brake.In order to reduce the impact of non-full-tooth meshing on the brake,a floating tooth band brake is proposed.Based on this scheme,the working characteristics of the brake and the influence of non-full-tooth meshing angles on the working parameters are explored.The results show that with the non-full-tooth meshing conditions,the braking time is shorter,but the drum speed after meshing is faster,and thus the impact torque during collision is greater.Therefore,the non-full-tooth meshing conditions should be avoided.
