Large torque and smooth transmission system design of raising machine

To improve the transmission performance of raising machine is one of the important ways for enhancing the raising style and quality of fabric.According to the working principle and the required raising process parameters,the transmission system of raising machine is innovatively designed for large torque and smooth driving by using the transmitting features of helical gears.The designed system is analyzed with kinematics and dynamics,and finite element analysis of the helical gears contact and statics analysis of needle roller are carried out.The results showed that the meshing of helical gears is a large torque and smooth transmitting process of gradually entering and withdrawing,and the contact stress and strain become smaller enough to meet the design requirements.In the course of transmission,the force acting upon the needle roller is even,and with smaller stress and deformation,and the raising quality requirements of fabrics is ensured.Therefore,the large torque and smooth transmission system is developed with advantages of higher dynamic performance and stability.
