introduction：Abstract：The traditional method of structure and stiffness analysis of truck scale table is to simplify the truck scale table into a simple beam，Because its model is too simplified，The reliability of the calculation results is poor、Shortcomings such as inability to perform local stress and strain analysis。Textual useANSYSFinite element analysis software，rightSCSSeries of automobile scale platform for analysis。The stiffness is checked on the basis of solid modeling，The emphasis is on checking the limit load when the truck scale is overloaded，It is concluded that the strength index should also be the main checking index during overload，Reasonable suggestions for improvement are given，It provides a valuable reference for the design and production of truck scales。 keyword：A

introduction：In order to better help the majority of users with a good planetary reducer，In this paper, the causes of shaft breakage of reducer and drive motor are analyzed，How to properly install the broken shaft of the planetary reducer is introduced in detail。Some users drive the output shaft of the reducer after several months of operation。Why did the reducer break the output shaft of the drive motor？For this purpose we looked at the output shaft cross section of the drive motor，It is found that the cross section of the output shaft of the reducer is almost exactly the same。The outer ring of the cross section is brighter，And the more toward the axis of the section color darker，It breaks at the end of the shaft！This fully explains the resulting drive motor output shaft break
