The core of preventing cracks in the NGW11-6.3 planetary gear reducer frame is to control stress, optimize assembly, match working conditions , and prevent the frame from bearing loads or stresses beyond the limit through multi-link management and control.
Design and material optimization
Calculate the strength of the machine base according to actual working conditions, appropriately increase the wall thickness or set reinforcement ribs at stress concentration locations (such as bolt holes and bearing seats).
Materials that meet the tensile strength and toughness standards are selected, and the internal quality of the castings must be strictly controlled to avoid defects such as blisters and pores.
After the machine base is cast, it is fully aged to eliminate residual internal stress and reduce the risk of cracking.
Installation and Assembly Specifications
Make sure the installation surface is flat and clean, and the anchor bolts are tightened evenly to the specified torque to avoid over-tightening or uneven stress.
Strictly calibrate the coaxiality of the input/output shaft, control the deviation within the equipment requirements, and reduce additional radial force.
Avoid hard knocking during assembly to protect the mating surface of the machine base and prevent local stress deformation from causing stress concentration.
Working conditions and operation control
It is strictly prohibited to operate overloaded, avoid frequent starts and stops and severe impact loads, and install a buffer device if necessary.
Regularly check the vibration value of the equipment, and promptly troubleshoot problems such as bearing wear, poor gear meshing, etc. that cause vibration to exceed the standard.
Strengthen protection under harsh working conditions (such as high temperature and dusty conditions) to prevent the machine base from being affected by environmental corrosion or temperature stress.
Manufacturing and quality control
Improve the machining accuracy of the machine base, ensure the flatness and dimensional tolerance of key mating surfaces, and reduce the impact caused by assembly gaps.
Before leaving the factory, conduct non-destructive testing (such as ultrasonic testing) on the machine base to check for internal hidden defects.
Establish a quality traceability system to ensure that materials, casting, processing and other links meet technical standards.
