摘　　要：根据组合辊的工作机理,对其外载转矩进行了分析,并以GM1400×800高压辊磨机组合辊为参照,研究了结构参数与其承载转矩的关系。结果表明:组合辊承载转矩随配合面长度、组合辊外径和摩擦因数的增大而增大;当过盈量较小时,组合辊承载转矩随过盈量的增加呈线性增大,当单边过盈量超过0.62mm时,组合辊承载转矩随其增大而减小;组合辊承载转矩随配合面半径增加呈抛物线分布,当配合面半径R=410mm时,承载转矩取得最大值10.4MN·m。According to the working mechanism of combined roller, the external load torque is analyzed, and the relationship between structure parameters and load torque was studied with the combined roller of high pressure grinding mill of GM1400 × 800 as reference. Results indicate that the load torque of combined roller increases along with the length of match surface, the diameter of combined roller and friction coefficient. The load torque of combined roller increases linearly with the increase of magnitude of interference when magnitude of interference is small. However, the load torque of combined roller decreases when unilateral magnitude of interference is more than 0. 62 mm. The load torque of combined roller presents a parabolic distribution with the increase of matching surface radius, and the load torque achieves the maximum of 10.4 MN ~ m when matching surface radius is 410 mm.
