Alignment device for speed reducer support and reaction kettle

The utility model provides an alignment device for a speed reducer support and a reaction kettle. The alignment device for the speed reducer support comprises a telescopic guide rail assembly, the telescopic guide rail assembly is supported above the speed reducer support through the cushion block; the frame type gradienter is arranged in the middle of the telescopic guide rail assembly; a probe of the laser assembly is arranged on the frame type gradienter; the scale is vertically arranged at the extending end of the telescopic guide rail assembly so as to be spaced from the probe, and laseremitted by the probe can irradiate the scale. The problem that in the prior art, when a speed reducer support is aligned, large deviation exists is solved. 本实用新型提供了一种用于减速器支座的找正装置及反应釜。其中，用于减速器支座的找正装置包括：伸缩导轨组件；垫块，伸缩导轨组件通过垫块支撑在减速器支座的上方；框式水平仪，框式水平仪设置在伸缩导轨组件的中间位置处；激光组件，激光组件的探头设置在框式水平仪上；标尺，标尺立置在伸缩导轨组件的伸出端上以与探头间隔设置，探头射出的激光能够照到标尺上。本实用新型解决了现有技术中减速器支座进行找正时存在较大偏差的问题。
