双通道直线振动筛是目前我国煤炭企业使用率较高的一种振动筛。双通道直线振动筛也广泛应用于冶金、煤炭、化工、耐火、水泥、陶瓷、建材、粮食、矿山、建材、电力等各行各业中,用于对各种物料不同程度的分级要求作业。双通道直线振动筛采用双电机带动两根轴,两根轴做反向同步回转,从而使偏心块也做反向同步回转,产生离心力,使筛箱产生振动。筛箱振动使物料产生向前和向下两个方向的运动,从而使物料在筛面上便沿着与这个方向成一定角度的抛挣和筛分。主要通过对短轴,偏心块,筛框的设计,对轴承的选取和校核,对轴的校核等来完成直线振动筛的设计。传统的振动筛的设计,筛子筛框、横梁的等尺寸过大,整机重量过大,所需激振力及相应激振器的尺寸也过大,会带来零部件易损坏,整机的可靠性和寿命降低等许多问题。因此研究双通道的结构,可较好地解决振动筛大型化所带来的问题

Abstract
Vibrating straightly bolter is a kind of oscillation bolter that current our country choose the coal plant usage at the bolter the too extensive applying straightly in the metallurgy, building materials, chemical engineering, refractor, cement, ceramic, food, mine mountain, coal, building materials, electrical power...etc. every trade inside, used for the operation of graduation to differ the degree to every kind of the bolter the adoption straightly the dipeptide electrical engineering arouse two indogen axis, two indogen axises make the anti - faces the synchronous turn-over, from and make lack of impartiality the cake to also make the anti - face synchronous turn round, the centrifugal force of the creation, make bolter box occurrence bolter box oscillation make material generated forward the sum gets down two runnings of direction, from but material is on the bolter face then along this direction the certain angle throws the material and bolter bat primarily to the brachyaxis, eccentricity cake, the design of the crid of bolter, to the select of the bearing and school riboside, come to the design that over rectilinear vibrate bolter to the axial school riboside iso Conventional vibrating screen, sieve screen frame, beams and other oversized, heavy weight machine, the required excitation force and the corresponding size of the exciter is also too large, fragile parts will bring the whole machine reliability and lower life expectancy and many other issues. Therefore, the structure of dual-channel, shaker can sol
