ANSI/AGMA 6034-B92-1992 pdf free.Practice for Enclosed Cylindrical Wormgear Speed Reducers and Gearmotors.
ANSI/AGMA 6034 applies to the rating and design of enclosed cylindrical worrngear speed reducers and gearmotors having either sohd or hollow output shafts and single or multiple reductions, including other types of gearing used in conjunction with cylindrical worrngearing. The rating and design considerations contained in this standard are valid for rotational speeds not greeter than 3600 rpm and sliding volocitics at the mesh of not more than 6000 Wmin (30 rWs).
The knowledge and judgment required to evaluate the various rating factors come from years of accumulated experience m designing, manufacturing, and operating gear units. Empirical factors given in this standard are suited to the particular use shown. This standard Is intended for use by the experienced gear designer, capable of selecting reasonable values for the factors. It is not intended for use by the eengineenng public at large.
No limitation is placed on the method of producing the worms and gears, but the tooth form of the gear must be conjugate to the thread form of the worm. See AGMA 341.02, Design of General Industrial Coarse-Pitch Cylindrical Worm Geanng.
1.2 ExceptIons
This standard does not apply to cylindrical wormgear reducers which are designed or used as speed increasers.
This standard covers only the pitting resistance and wear rating of wormgeanng, and does not cover any strength rating method.
1.3 System considerations
This standard does not attempt to address complete drive systems, torsional vibration, critical speeds, or other types of vibrations which may affect operation of enclosed cylindrical worm gear reducers.
