The Design Of High Speed Heavy-Duty Double Shaft Output Bevel Gear Reduce

As a basic transmission component,gears are stable in their transmission ratio and can operate under high-speed and heavy-load conditions.They are widely used in high-speed railways,machine tools,and petroleum,chemical,metallurgical and mining machinery industries.At the same time,due to its complex space profile shape,numerous research topics have been proposed for many fields such as geometric design,transmission analysis,processing and manufacturing.With the wide application and development of computers,it is necessary not only to perform three-dimensional modeling of gears,but also to meet the needs of finite element analysis,mechanism motion analysis,and dynamic analysis.The mechanical properties and working performance of the gear system have an important influence on the entire machine.The working state of the gear transmission system is very complicated.Not only the load conditions and power devices are various,but external excitations introduced by the prime mover and the load will appear.The time-varying meshing stiffness,gear transmission error,and backlash can also occur.Internal incentives caused.Therefore,mechanical products have more prominent requirements for the dynamic performance of gear systems.In this paper,a high-speed and heavy-duty double-shaft output bevel gear reducer is designed and its structure design,strength analysis,modal analysis and dynamics simulation are performed.The design method is as follows:First,select the motor and determine the gear ratio,worm gear,and the number of teeth and modulus of each gear.Then,the creo modeling software was used to accurately 3D model the bevel gear accelerator and perform interference check.The strength analysis of the gears,the core component of the reducer,was further performed.The theoretical and finite element simulation values of tooth surface contact stress and root bending stress were obtained.Other key components such as input shaft and output shaft were also performed.Finite element strength analysis,strength is in line with design requirements.Finally,the dynamic simulation of the gear through adams.
