S116温砂机的主轴与大伞齿轮装配原设计为平轴端。材质为HT150的整铸大伞齿轮重量为600kg以上,在辗盘底下装配大伞齿轮受空间位置限制,对中性差,既费力又费工时,甚至会危及工人的安全。尤其是大伞齿轮是混砂机的薄弱零件,齿面容易磨损折断,使用不到一年就得更换,一般一个大修期内更换大伞齿轮1～2次。故改善装配工艺,成了急待解决的问题。根据实践经验,我们结合设备大修,在更
S116 temperature sand machine spindle and large bevel gear assembly originally designed for flat-shaft end. Material cast HT150 large bevel gear weight of 600kg or more, in the bottom of the gear plate assembly under the big space bevel gear position restrictions on the poor, both laborious and time-consuming, and even endanger the safety of workers. Especially the big bevel gear is the weak part of the sand mixer, the tooth surface is easy to wear and tear, and the replacement must be replaced in less than one year. Generally, a large bevel gear is replaced 1 or 2 times during an overhaul period. Therefore, improving the assembly process has become an urgent issue to be solved. According to practical experience, we combine equipment overhaul, more
