目前,国内外链轮体的主要结构形式普遍采用整体式结构,但整体式链轮轴组换向、维修困难;相对而言,分体式链轮轴组在维修成本及便利性方面有极大的优势。为此,根据经典理论力学原理,对新型结构的分体式链轮体进行受力分析研究,采用材料力学计算理论进行强度校核计算,并与有限元分析计算结果进行比较验证,得到分体式链轮体连接结构设计的校核计算方法。文中提出的分体式链轮受力分析研究方法,可以为连接设计计算和有限元分析提供必要的载荷和约束条件。分体式链轮通过在上、下链轮体之间设置圆柱销来传递转矩,能够保证现有大功率重型刮板机链轮轴组在安装空间受限、连接螺栓数量有限情况下的连接可靠性,为今后类似链轮体的设计提供了参考依据和理论指导。
At present
the main structural form of sprocket body generally adopts the integral structure at home and abroad
which is difficult to reverse and maintain. The split sprocket shaft group has great advantages in maintenance cost and convenience compared with the integral sprocket shaft group. According to the classical theoretical mechanics
the force analysis of the split sprocket body with new structure is carried out. It is combined with the results of finite element analysis
and then the calculation method of the split sprocket body connection structure design is obtained. This research provides the research method of force analysis of the split sprocket
which can provide necessary loads and constraints for design calculation and finite element analysis. When the split sprocket body is connected by connecting screws
cylindrical pins are set between the upper and lower sprocket bodies to transmit torque
which can ensure the connection reliability of the scraper sprocket of the existing high-power heavy scraper under the conditions of limited installation space and limited number of connecting bolts. Thus it can provide reference and theoretical guidance for the design of similar sprocket bodies in the future.
