Every worm gear drive has a thermal rating as well as a mechanical rating. Most engineers focus on the mechanical side. The drive that fails from overheating in summer was within mechanical spec — but was operating above thermal equilibrium without anyone calculating the heat balance.<\/p>\n

The Drive That Failed in Summer but Not in Winter<\/h2>\n

A Korean printing plant installed a new worm gear drive on a roll-handling system in October. The drive ran without incident through November, December, January, and February. In mid-July, during the hottest week of the year, it began making noise and running hot. By August it had failed from scuffing of the worm thread flanks. The drive had been correctly specified for the mechanical load. The thermal specification had never been calculated.<\/p>\n

The operating conditions in October: ambient temperature 18 degrees C, housing equilibrium temperature approximately 52 degrees C. In July: ambient temperature 34 degrees C (unventilated machine room), housing equilibrium temperature approximately 75 degrees C. At 75 degrees C, the ISO VG 460 mineral oil had viscosity below 100 cSt — inadequate for the required EHD film thickness at this sliding velocity. The drive was mechanically rated for the load at all seasons. It was thermally rated only for winter.<\/p>\n

Thermal calculation is not complex — it requires four parameters and 10 minutes of calculation. This guide provides the framework for calculating equilibrium housing temperature, identifying whether a drive is within its thermal limit, and specifying the correct cooling or oil upgrade if it is not.<\/p>\n

\n

Step 1: Calculate Heat Generated — Power Loss in the Gear Mesh<\/h2>\n

A worm gear drive is an inefficient power transmission device by the standards of other gear types. Between 25% and 50% of the input power is converted to heat at the gear mesh contact. This heat must be continuously rejected through the housing surface to the ambient environment. If heat generation exceeds heat rejection, the housing temperature rises until a new equilibrium is reached — or until the lubrication system fails.<\/p>\n

\n
Heat Generation Formula<\/div>\n
Q_loss (W) = P_input (W) x (1 – eta)<\/div>\n
P_input = motor shaft power (W) = motor rated power x load factor<\/span>
\neta = worm gear mechanical efficiency (decimal) = tan(lambda) \/ tan(lambda + rho-prime)<\/span>
\nExample: 3 kW input at 60% efficiency: Q_loss = 3,000 x (1 – 0.60) = 1,200 W continuous heat generation<\/span>
\nAt 75% efficiency: Q_loss = 3,000 x (1 – 0.75) = 750 W — 37% less heat for the same power<\/span><\/div>\n<\/div>\n

The efficiency is not fixed — it varies with lubricant viscosity (which varies with temperature), which is why the thermal problem is self-reinforcing. A drive starts cold, oil viscosity is high, efficiency is moderate (say 60%). As the housing heats up, oil viscosity drops, lubrication film thickness decreases, friction coefficient increases, efficiency falls further (perhaps to 55%), and heat generation increases from 1,200 W to 1,350 W. This is the thermal feedback loop described in the efficiency guide (B4)<\/a>, and it is why thermal calculations must be performed at operating temperature, not ambient.<\/p>\n

\n

Step 2: Calculate Housing Equilibrium Temperature<\/h2>\n

The housing reaches thermal equilibrium when heat generation equals heat rejection through the housing surface. The equilibrium temperature depends on heat loss, heat transfer coefficient, and housing surface area.<\/p>\n

\n
Thermal Equilibrium Equations<\/div>\n
\n
Heat rejection (natural convection)<\/div>\n
Q_reject (W) = h x A_housing x (T_housing – T_ambient)<\/div>\n
h = convective heat transfer coefficient = 10-15 W\/m2K (natural convection), 25-40 W\/m2K (forced air)<\/div>\n<\/div>\n
\n
Equilibrium condition<\/div>\n
Q_loss = Q_reject<\/div>\n
When this equation is satisfied, temperature is stable<\/div>\n<\/div>\n
\n
Solving for housing temperature<\/div>\n
T_housing = T_ambient + Q_loss \/ (h x A_housing)<\/div>\n
This is the steady-state housing surface temperature<\/div>\n<\/div>\n<\/div>\n

Example calculation: 3 kW input, 60% efficiency, Q_loss = 1,200 W. Housing surface area A = 0.08 m2 (typical small worm gear housing). Natural convection h = 12 W\/m2K. Ambient 25 degrees C. T_housing = 25 + 1,200 \/ (12 x 0.08) = 25 + 1,250 = 1,275 degrees C — clearly wrong, because the formula is only valid for the cooling surface, not the total housing surface area. In practice, the effective radiating area is typically 60-80% of the housing total surface area. Recalculating with effective area 0.06 m2: T = 25 + 1,200\/(12 x 0.06) = 25 + 1,667 — still clearly problematic. The correct interpretation: this drive cannot reject 1,200 W by natural convection from a 0.08 m2 housing. Forced cooling or a more efficient drive configuration is required.<\/p>\n

\n

The thermal rule of thumb:<\/strong> A natural convection worm gear housing can reject approximately 6-10 W per square metre of housing surface per degree C of temperature rise above ambient. A 0.08 m2 housing at 50 degrees C rise can reject 0.08 x 8 x 50 = 32 W. If your Q_loss exceeds this figure significantly, forced cooling or a higher-efficiency drive is required. For a 1,200 W heat loss, the required temperature rise to reject it naturally would be 1,200 \/ (0.08 x 8) = 1,875 degrees — physically impossible. The drive needs forced cooling or a much larger housing.<\/p>\n<\/div>\n

\n

Factors That Raise or Lower Operating Temperature<\/h2>\n
\n
\n
\n

Gear Ratio \/ Lead Angle<\/h4>\n

+<\/span><\/p>\n<\/div>\n

High ratio (single-start at 50:1) = shallow lead angle = low efficiency = more heat. Multi-start worm at same ratio = higher lead angle = better efficiency = less heat. If thermal rating is the constraint, multi-start worm specification is the primary design lever.<\/p>\n<\/div>\n

\n
\n

Operating Speed<\/h4>\n

-\/+<\/span><\/p>\n<\/div>\n

Higher worm shaft speed increases sliding velocity at the mesh, shifting the lubrication regime toward EHD (lower friction, higher efficiency). However, higher speed also means more mesh cycles per unit time, so heat generation per unit time may still increase. Thermal rating varies with speed.<\/p>\n<\/div>\n

\n
\n

Oil Viscosity<\/h4>\n

–<\/span><\/p>\n<\/div>\n

Lower viscosity = better EHD film development at speed = lower friction coefficient = less heat generation. But viscosity that is too low does not separate surfaces adequately at low speed — mixed lubrication boundary regime means higher friction. Correct viscosity for operating conditions minimizes heat generation.<\/p>\n<\/div>\n

\n
\n

PAO vs Mineral Oil<\/h4>\n

-8 to -15 C<\/span><\/p>\n<\/div>\n

PAO has VI >150 vs 90-100 for mineral oil. At operating temperature, PAO of the same ISO VG grade maintains higher viscosity, providing better film — but also PAO has slightly lower friction coefficient (better boundary protection from the PAO base chemistry). Switching from mineral to PAO reduces operating temperature 5-15 degrees C.<\/p>\n<\/div>\n

\n
\n

Housing Surface Area<\/h4>\n

–<\/span><\/p>\n<\/div>\n

Larger housing = more surface to reject heat = lower equilibrium temperature. For a drive at its thermal limit, a larger housing specification (same gears, larger housing) may resolve the thermal problem without any other change. Worm gear reducers with extended fin housings are available.<\/p>\n<\/div>\n

\n
\n

Ambient Temperature<\/h4>\n

+<\/span><\/p>\n<\/div>\n

Ambient temperature directly adds to housing equilibrium temperature (T_housing = T_ambient + delta_T). A drive that is within thermal spec in winter may fail in summer if it was designed for ambient 20 degrees C and the summer ambient is 38 degrees C — the delta_T budget is consumed by the ambient increase.<\/p>\n<\/div>\n<\/div>\n

Oil Viscosity at Operating Temperature — The Critical Variable<\/h2>\n

The thermal performance of a worm gear drive depends critically on the oil viscosity at operating temperature — not at ambient. Specifying ISO VG 460 mineral oil based on its 40 degrees C viscosity (460 cSt) misrepresents what the oil actually provides at the operating temperature inside the housing.<\/p>\n
