电动滚筒的主轴
The spindle of an electric roller
1.只承受弯矩,如改向滚筒组的轴。
1. bending moments, such as the axis of the roller group.
2.轴同时承受弯矩和扭矩,如传动滚筒组的轴。
The 2. axis simultaneously bears the bending moment and torque, such as the shaft of the driving drum group.
轴的材料一般是经过轧制或锻造的碳素钢或合金钢,通常的材质是中碳钢,四十五号钢最为常用的,对于受力较大且尺寸受到限制的轴,以及某些特殊要求的轴可用合金钢,选用材质为四零铬,根据需要,电动滚筒轴一般需经过热处理或表面强化处理,小型电动滚筒,以提高其力学性能和耐磨性等,在一般温度下,合金钢和碳素钢的弹性模量相差很小,微型电动滚筒厂,故采用合金钢不能提高轴的刚度。
The shaft material is generally through carbon steel or alloy steel
rolling or forging, usually is made of carbon steel, forty-five steel
is the most commonly used, the larger force and the size limit shaft,
and some special requirements of axle available alloy steel, the
material is 40 chromium, according to the needs of general electric
roller shaft after heat treatment or surface treatment, small electric
drum, in order to improve the mechanical properties and wear resistance,
in general temperature, elastic modulus of the alloy steel and carbon
steel are very small, micro electric roller factory, so the use of alloy
steel can improve the stiffness of the shaft.
轴的材质方面一般会经JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具 调质处理,对于传动滚筒组,当轴强度指标不满足要求时也可选择合并经调质处理,电动滚筒按对称循环弯曲许用应力校核。
The material axis generally after quenching and tempering, the
driving roller group, when the strength index does not meet the
requirements can also choose to merge after quenching and tempering,
electric drum according to the symmetrical cyclic bending allowable
stress check. |
