一、产品概述Brief
电动滚简作为皮带运输机和提升等设备的动力.广泛应用于矿山、冶金.化工、煤炭、建材、电力。轻工，粮食及交通运输等部门。
电动滚筒与一般减速机构相比，具有结构紧凑，体积小，重量轻，密封性好， 安装方便，维修简单等优点。.可用于粉尘大。潮湿.泥泞。露天等环境恶劣场所，环境温度在-20°C ~40'C，一般不用于输送高温物料及易爆场所，海拔高度不超过1000米，并应水平安装。
我公司参照机械部JB/T7330-94标准设计生产的电动滚简有定轴齿轮、行星齿轮.摆线针轮三种传动形式，安装形式有电机内置(内装)、 电机外置(外装)以及用于移动式输送机上的移动式三种。共有Y吓(即TDY75). YB. wBJ (WDT. wxT )以及YY,等六大系列产品，各产品均可包胶，其中胶面有平胶、”人” 字胶及菱形胶三种， 除J DY,型移动滚简外均可附加逆止功能。电机内置时有油冷和油浸式两种:电机外置时有卧式直列型、立式电机型、卧式垂直型三种装配形式，电动机采用Y系列电机配套. 如选用隔爆型电机可用于隔爆要求场所，另外还可配加ZL型弹性柱销齿式联轴器，YOX型液力偶合器以及YWZ型液压推杆制动器。
Being a drive of belt transporter and lifting equipment, the electric roller is widely applied in metallurgy, mining, chemical industry. coal industry, building materials, powering, light industry, foodstuff and transportation.
Electric roller has such property as fine structure, low volume, light weight, fine sealing and easy assembling. It can be used in such environment as heavy powder, muddy, wet and outdoors. The ambient temperature is -20'C一40'C. Usually it isn't applied in altitude over 1000m, also it should be assembled levelly.
The electric roller we produce on standard of JB/T7330-94 of mechanism department includes three types, the fixed shaft gear, planet gear and cycloid pin wheel. The installing form includes inside the motor, outside the motor and movable. There are six series products,丫听(TDY75). YB下. WBJ (wDJ . wx )and Y DY, The whole products can be glued.
The glue face can be classified into flat glue, r type glue and rhombic glue. The whole roller except」DY, movable roller can be equipped with hold back parts. The oil cooling and immersed type are applied when the motor is inside and when it is outside there are horizontal type, solid motor and horizontal vertical type. The motor is assembled with Y series motor. If the anti-explosive environment is wanted, you can elect anti-explosive motor. Also the ZL type stretching tooth connector, YOX liquid coupler and YWZ type hydraulic-pressure handspike arrester.
