Testing Process:
· QA DOC: Chemical Composition Report, Mechanical Properties Report, UT Report, Heat Treatment Report, Dimensions Check Report
· The data on chemical composition report and mechanical properties report are approved by third party, HangZhou Ship Material Research Institute, CSIC.
· UT test: 100% ultrasonic test according to EN15718-3, SA388, Sep 1921 C/c etc.
· Heat Treatment Report: provide original copy of heat treatment curve/time table.
Other than Girth equipment, we also can make pinion, shaft, roller, grinding mill go over, assist roller of kilns, marine components and so on. Any query or needs pls phone us freely.
The efficiency of a worm gear transmission relies upon to a large extent on the helix angle of the worm. Multi-threaded worms and gears with greater helix angles have proven to be twenty five% to 50% far more efficient than single-threaded worms. The sliding motion of the worm meshing with or meshing with the worm gear outcomes in considerable friction and loss of effectiveness in comparison to other kinds of gears. Improve efficiency with hardened and ground worm change bronze worm gears.
