What is the different between double envelop worm gearbox and conventional worm gearbox
Double envelop worm gear box also called conedrive worm gearbox , SGR double envelope worm gear box is substantially different to conventional worm designs.
A point on the planar primary-enveloping line acting twice at different moment, generated worm wheel profile .
FIG1 shows the worm thread contact pattern is longer than conventional worm threads.
FIG2 shows the worm thread enveloping gear more oil and lubricate the contact profile better than conventional worm threads, it makes the efficiency higher.
FIG3 shows the worm threads have more contact teeth than conventional worm threads, so it is more stronger .
