封面照片是进行蜗杆减速器测试试验的试验台。该试验台是由西安重型机械研究所设计制造的,也是我国首次采用液压加载封闭式的减速器试验装置。它可以用于圆柱齿轮、垂直轴圆锥齿轮和蜗轮蜗杆减速器(除立式减速器外)以及联轴器等试验。本试验台由拖动直流电机,液压加载器(直接装在陪试齿轮箱上),两个陪试齿轮箱(中心距为600+600=1200mm,JC型传感器等部分组成。试验台可测试的数据:输入扭矩M_1,输出扭矩M_2,功率N_1,效率η,减速器箱体内的油温T和载荷M,转速n随时间t变化的曲线。试验台的主要特点:
The cover photo is a test rig for a worm reducer test. The test stand is designed and manufactured by Xi’an Heavy Machinery Research Institute and is also the first hydraulic loading and closing reducer test device in our country. It can be used for cylindrical gear, vertical shaft bevel gear and worm gear reducer (except vertical reducer) and coupling test. The test stand by the drag DC motor, hydraulic loader (directly attached to the pilot gear box), two accompanied test gear box (center distance of 600 +600 = 1200mm, JC sensors and other components. Of the data: the input torque M_1, the output torque M_2, the power N_1, the efficiency η, reducer tank oil temperature T and the load M, speed n with time t curve. The main features of the test bench:
