Worm and WormGear Design Equations and Calculator. Gears Engineering and Design. l = lead of a worm which is the distance any one thread advances in a single revolution. Lead Angles: There are Fifteen standard lead angles: 0.5, 1, 1.5, 2, 3, 4, 5, 7, 9, 11, 14, 17, 21, 25, and 30 degrees.
• Features of Worm Gearing It is used to transmit power between two non-intersecting shafts; Power is typically transmitted from worm to worm gear; A set of worm and worm gear can be designed to self-lock; that is, the worm gear can’t back-drive the worm;
The monograph describes general principles of worm gear systems and methods of creation of dynamic model of worm reducer or of an entire drive. It indicates possibilities of reduction of dynamic load of a gear in the mode of frequent start-ups and halts of the drive.
Worm gear design parameters. Worm gears provide a normal single reduction range of 5:1 to 75-1. The pitch line velocity is ideally up to 30 m/s. The efficiency of a worm gear ranges from 98% for the lowest ratios to 20% for the highest ratios.
28 wrz 2024 · Calculation Example: Worm gears are a type of gear that is used to transmit power between two shafts that are perpendicular to each other. They are often used in applications where high torque is required, such as in winches and hoists.
Formula For Worm Gears. (Based on Diametral Pitch) NOTE: Tooth data (Addendum, Full Depth, Etc.) is same as for spur gears. G-92.
First step of the calculation. We first calculate the instan-taneous load distribution between the flanks of the worm threads and the flanks of the gear teeth, with allowance for the operating geometry and the materials used.
