Foreword
This standard is GB/T 16444-1996 "plane double enveloping worm reducer series, lubricating and load carrying capacity" and
GB/T 16446-1996 "plane double enveloping worm reducer technical conditions" for the integration of a revised standard.
This standard replaces GB/T 16444-1996 and GB/T 16446-1996.
This standard modifications are as follows.
--- Standard name changed to "flat double enveloping worm reducer";
--- Normative references using the latest standards, and removed the body not covered by the reference standard;
--- Size and position of the anchor bolt hole worm input length of the worm and the worm gear unit mounted on under-mounted gear unit were
modify;
--- Rated input power table center distance 400mm above the rated input power and rated output torque has been modified.
Appendix A of this standard is the data appendix.
