强力尼尤带传动与普通平皮带或三角橡胶带比较,具有负载能力高、受力伸长量少、运行平稳和传动效率高等优点。它被广泛地用于中小型造纸机的总轴传动。但是,过去大多参照普通平皮带的计算公式设计,往往忽视了尼龙带具有较大预拉力的特点,导致总轴窜动或轴承发热、早期破坏等后果。本文试从受力分析出发,提出总轴锥形带轮合理布局的设计力案。一、轴向推力的计算强力尼龙带给轴的压力 Q,等于尼龙带两边拉力的合力。由于尼龙带的预拉力较大,当带速度V≤25m/s 时,可用下式计算 Powerful nylon belt drive belt with the ordinary flat or triangular rubber belt compared with a high load capacity, less elongation force, smooth operation and transmission efficiency advantages. It is widely used for the total shaft drive of small and medium sized paper machines. However, most of the past, referring to the design of ordinary flat belt formula, often overlooked the nylon pre-tension with a larger characteristic, leading to shaft movement or bearing fever, early damage and other consequences. In this paper, starting from the force analysis, this paper puts forward the design force case of the rational distribution of the total shaft conical pulley. First, the calculation of axial thrust Nylon strong force brought to the shaft pressure Q, equal to the resultant tension of nylon with both sides. Due to the larger pre-tension nylon belt, when the belt speed V ≤ 25m / s, can be calculated using the following formula
