What is the lubrication type encountered in worm wheel drives?

a) What is the chief consideration as far as the lubrication requirements for worm wheel drives go?

b) What type of lubricant is recommended for worm wheel drives?

Expert Solution

Operation of worm gears requires unique lubrication demands. The operation of worm gears is sideway sliding motion, hydrodynamic wedge is impossible to maintain, so worm gear will operate under boundary lubrication conditions.

a) The chief considerations are that lubricants must have high-temperature tolerance like oils with an ISO VG of 460 (AGMA Class 7) and higher as the working temperature may reach as high as 88-degree Celsius or higher. the lubricant must have good thermal and oxidative stability and viscosity.

b) types of gear oils:

1. compounded gear oils

2. extreme pressure gear oils

3. synthetic worm gear oils.

A worm & worm wheel gear is connected to a motor running at 1000 rpm. Further 03 a gear train is formed using worm wheel having 100 teeth and module of 2mm as a driving gear. Gear “A” having 80 teeth is concentric with the worm wheel which in turn drives gear “B” in a ratio of 1:1. Gear “C” having 60 teeth and “B” are compound gears. Gear “C” is the driving gear for a simple gear train having...
