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.

电动滚筒输送机械

Electric roller conveyer

   一，首先我们说下有中国特色的一个类型：摆线针轮传动的电动滚筒，该结构特征的除少量国家针对性的应用外，电动滚筒供应，也就再中国这边使用范围很广，该类型的输送线电动滚筒有优点有：大功率，很小的线速度。

, first of all we said that under Chinese characteristics of a type: electric drum cycloid drive, the structure characteristics of the country in addition to a small number of specific applications, electric drum supply, then Chinese here the use of a wide range, the transmission line type electric roller has the advantages are: high power very small, line speed.

   二，再给大家说的是行量齿轮传动的电动滚筒，该传动结构的电动滚筒在国外应用的很广泛，优点有：工作平稳，负载大，体积小，重量轻等，缺点是一旦有问题，电动滚筒，维护起来很麻烦。

Two, give you is that electric roller quantity of gear transmission, the electric roller transmission structure in foreign applications is very broad, has the advantages of stable operation, large load, small volume, light weight, the disadvantage is if there is a problem of electric drum, maintenance is very troublesome.

   三，最后给大家说的是内国外都应用很广泛的减速器装置，叫定轴齿轮传动的电动滚筒，该传动结构的电动滚筒优点有：生产容易，安装维护便捷，性能平稳可靠，结构很简单，低噪音。

Three, finally tell you is that in foreign application of reducer is widely, electric drum called fixed axis gear transmission, electric roller transmission structure has the advantages of easy production, convenient installation and maintenance, stable and reliable performance, simple structure, low noise.
