distributing the lubricant of the Wuma variable gearbox

In vertical variable gearbox, a special problem of lubrication exists.
The vertical gear reducer housing is commonly employed as a lubricant reservoir and the lower shaft bearings which mount the vertical shafts are below the level of lubricant in the housing so that they ice may simply be exposed to the lubricant in the housing. However, the upper shaft bearings for the vertical shafts are above the level of lubricant in the housing and it is, therefore, necessary to provide means for drawing lubricant from the housing, lifting it to the level of upper bearings and then distributing the lubricant to all of the upper bearings.

A simple approach with AC Motor Worm Gearbox

Using a Wuma AC Motor Worm Gearbox
When cutting a worm on a lathe fitted with a gearbox the comments made  regarding metric threads with a gear box still apply. This, as you can set the box to 8TPI and set up the change wheels as though the gear box was not fitted as its input and output rotation are identical.
The mechanical variable speed gearbox is though a relatively simple method for achieving the majority of common DP values. This entails fitting just a 55 tooth driver and a 35 tooth driven and using the gearbox to establish the values required. The table shows just a few of the possibilities but other values are easily determined. Typically, as 32 DP uses the 16TPI setting then 18TPI would result in 36 DP.

Hypoid Gear Reducer associated applications

Switching speeds of the IGBTs in a Hypoid Gear Reducer can range from 2 KHz to 15 KHz. Today's newer PWM designs use power IGBTs, which operate at these higher frequencies. By having more pulses in every half cycle, the motor whine associated with Hypoid Reducer applications is reduced because the motor windings are now oscillating at a frequency beyond the spectrum of human hearing. Also, the current wave shape to the motor is smoothed out as current spikes are removed. By varying the width of the pulses in each half cycle, the average power produced has a sine-like output. The number of transitions from positive to negative per second determines the actual frequency to the motor.

highly reliable of the vertical gear reducer

The Wuma vertical gear reducer has become the most commonly used drive controller because it works well with motors ranging in size from about 1/2 hp to 500 hp.

rugged reliability of Wuma combination worm gearbox

Wuma combination worm gearbox - In applications where very high torque capacity and shock loading resistance are mandatory, double-enveloping worm drives provide rugged reliability. Because our worm gearboxes offer high ratio reduction in a single stage, these drives provide a compact, low profile that is ideal for many types of mining equipment like feeder breakers, shuttles, and conveyors. Double-enveloping worm drives are also an excellent choice for rock crushers, which require high shock resistance.

The concept of worm gearbox

RV Worm Gear Reducer provide several distinct advantages over cylindrical worm gears, including increased torque throughput, improved accuracy, and extended life. The concept of worm gearbox originated in antiquity. Archimedes is generally acknowledged as the inventor of the worm gear, using a screw to rotate a toothed wheel. Leonardo Da Vinci envisioned the double-enveloping worm gear nearly 500 years ago. Although Da Vinci came up with the concept for double-enveloping worm gearing, it was Samuel Cone who developed efficient techniques to manufacture the double-enveloping worm gear in the late 1920's.
