ZA – wormgear with straight-line (trapezoidal) tooth profile in axial.

Globoid wheel and worm (high outputs, compact design, special production,.

Globoid worm/cylindrical wheel (not used).

Cylindrical worm/globoid wheel – most frequent (power transmissions,Ĭompact design, divided by cylindrical worm shape – see below).

Low torque, manual drive, adjusting mechanisms, point contact of teeth, cheap

Cylindrical wheel/cylindrical worm (kinematical, non-power transmissions,.

Worm gearing is a special case of screw gearing with the angle of axes 90°Īnd a low number of pinion/worm teeth (mostly z1=1-4). This calculation deals with the most frequently used gearing with cylindrical

Vehicles and lifting equipment, textile machines, presses, conveyors, shears,ĭrums, hoists, ship propeller drives, planers, machine tools, cars. Worm gearing is used for power transmission in mixers, vertical lathes, More demanding and expensive and the service life of such gearing is usually Require using deficit nonferrous metals for wormgear rims. Losses and thereby lower transmission efficiency the endeavours for improvement The disadvantage is the large slip in the gearing causing higher friction Itįeatures quiet and silent operation and can be designed as a self-locking Transmissions), being of small size, low weight, and compact structure. Realize high transmission ratios i = 5 to 100, (up to i=1000 in kinematical Worm (globoid) gearing can transmit high outputs, the common ones being 50 toġ00 kW (optimum 0.04kW-120kW, extreme 1000 kW) within one stage, it is able to Paragraph "Information on the project" can be found in the document " Information Information on the purpose, use and control of the Information on the syntax and control of the calculation List of standards: ANSI/AGMA 6022-C93 (Revision of AGMA 341.02), ANSI/AGMAĦ034-B92 (Revision of ANSI/AGMA 6034-A87), DIN 3996, DIN 3975-1, DIN 3975-2 Hint: The comparative documentĬhoices of transmission can be helpful when selecting a suitable transmission type.
