Their drive wheel gearboxes must pack enormous load-bearing capacity into a chassis just 100-200 mm off the ground. The <strong>worm gear reducer<\/strong> solves this with its uniquely compact right-angle geometry, fitting inside a drive wheel module where no helical or planetary gearbox could physically fit. Our <a href=\"https:\/\/chinawormgearbox.xyz\/nn\/products\/\" style=\"color:#ff6f00;\">compact worm gearboxes<\/a> are engineered for mobile robot drive duty &#8211; delivering payload capacity, smooth motion control, and maintenance-free service life that AGV\/AMR manufacturers demand.<\/p>\n<div style=\"display:flex;gap:14px;flex-wrap:wrap;margin:20px 0;\">\n<div

start. The worm gear torque multiplication is highest at low speeds &#8211; exactly when most needed.<\/li>\n<li><strong>Long maintenance-free intervals:<\/strong> AGVs in 24\/7 distribution centres must operate for months between service stops. Our factory-sealed worm reducers use lifetime lubrication and sealed bearings.<\/li>\n<li><strong>Low acoustic output:<\/strong> Hospital and office-deployed AMRs operate near people. Worm drive sliding contact mechanism inherently produces lower gear mesh noise than helical or bevel alternatives.<\/li>\n<li><strong>Bidirectional operation:<\/strong> All standard worm gearboxes operate equally well in forward and reverse &#8211; essential for AGV drive wheels that must move in both directions and navigate around obstacles.<\/li>\n<li><strong>Shock load tolerance:<\/strong> AGVs encounter floor joints, ramp transitions, and collision events. Worm gear mesh is more tolerant of sudden load spikes due to distributed contact area across multiple worm thread turns simultaneously.<\/li>\n<\/ul>\n<p><img decoding=\"async\" src=\"https:\/\/chinawormgearbox.xyz\/wp-content\/uploads\/2026\/05\/nmrv-worm-gearbox.webp\" alt=\"compact NMRV worm gearbox for AGV mobile robot drive wheel application\" style=\"width:100%;max-width:720px;display:block;margin:24px auto;border-radius:8px;\" \/><\/p>\n<h2 style=\"font-family:Helvetica,sans-serif;color:#212121;margin-top:36px;\">Technical Specifications &amp; Selection Guide<\/h2>\n<div style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;\">\n<table style=\"width:100%;border-collapse:collapse;font-size:14px;min-width:720px;\">\n<thead>\n<tr>\n<th style=\"background:#ff6f00;color:white;padding:12px;text-align:left;border:1px solid #e65c00;\">Parameter<\/th>\n<th style=\"background:#ff6f00;color:white;padding:12px;text-align:center;border:1px solid #e65c00;\">Light AMR (&lt;100 kg payload)<\/th>\n<th style=\"background:#ff6f00;color:white;padding:12px;text-align:center;border:1px solid #e65c00;\">Mid-Range AGV (100-500 kg)<\/th>\n<th style=\"background:#ff6f00;color:white;padding:12px;text-align:center;border:1px solid #e65c00;\">Heavy-Duty AGV (&gt;500 kg)<\/th>\n<th style=\"background:#ff6f00;color:white;padding:12px;text-align:center;border:1px solid #e65c00;\">Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:#fff8e1;\">\n<td style=\"padding:10px;border:1px solid #eee;\"><strong>Ratio Range<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">10:1-30:1<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">20:1-50:1<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">40:1-80:1<\/td>\n<td style=\"padding:10px;border:1px solid #eee;\">Motor speed dictates wheel speed<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #eee;\"><strong>Output Torque (cont.)<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">30-150 Nm<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">150-500 Nm<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">500-1,500 Nm<\/td>\n<td style=\"padding:10px;border:1px solid #eee;\">Per drive wheel<\/td>\n<\/tr>\n<tr style=\"background:#fff8e1;\">\n<td style=\"padding:10px;border:1px solid #eee;\"><strong>Output Shaft<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">Hollow bore 20-35mm<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">Hollow bore 35-60mm<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">Hollow bore 60-100mm<\/td>\n<td style=\"padding:10px;border:1px solid #eee;\">Wheel axle passes through bore<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #eee;\"><strong>Housing Material<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">Die-cast aluminum (NMRV)<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">Aluminum or cast iron<\/td>\n<td style=\"padding:10px;border:1px solid #eee;text-align:center;\">Cast iron GGG40<\/td>\n<td style=\"padding:10px;border:1px solid #eee;\">Aluminum preferred for weight<\/td>\n<\/tr>\n<tr style=\"background:#fff8e1;\">\n<td style=\"padding:10px;border:1px solid #eee;\"><strong>Max.

A worm gearbox is right-angle &#8211; the motor mounts horizontally while the output shaft is perpendicular. This allows the motor to lie alongside the chassis rather than above the wheel, dramatically reducing the module contribution to overall vehicle height. For many AGV designs, the worm gearbox is the only single-stage solution that fits within the chassis envelope constraint.<\/p>\n<\/details>\n<details style=\"border:1px solid #ffcc80;border-radius:8px;margin-bottom:12px;overflow:hidden;\">\n<summary style=\"background:#fff8e1;padding:14px 16px;cursor:pointer;font-weight:bold;font-size:15px;color:#e65c00;\">Does the worm gearbox support regenerative braking in AGV deceleration?<\/summary>\n<p style=\"padding:14px 16px;font-size:14px;color:#444;line-height:1.8;margin:0;\">For worm gearboxes with ratios above approximately 30:1, the self-locking characteristic means the gearbox will resist back-drive from the wheel &#8211; this limits regenerative braking effectiveness. For AGVs where regenerative braking is a design priority, we recommend selecting a ratio below 20:1 and implementing motor braking through the drive controller. For most warehouse AGVs where regenerative recovery is not a primary goal, the self-locking property provides free braking force when motor power is cut.<\/p>\n<\/details>\n<details style=\"border:1px solid #ffcc80;border-radius:8px;margin-bottom:12px;overflow:hidden;\">\n<summary style=\"background:#fff8e1;padding:14px 16px;cursor:pointer;font-weight:bold;font-size:15px;color:#e65c00;\">What hollow bore diameter range is available for wheel axle integration?<\/summary>\n<p style=\"padding:14px 16px;font-size:14px;color:#444;line-height:1.8;margin:0;\">Our standard hollow bore output shaft sizes range from 20 mm (NMRV25 series) to 120 mm (cast iron size 150 frame). Custom bore diameters within these bounds are available. The hollow bore allows the wheel axle to pass directly through the gearbox output shaft &#8211; creating a clean, compact drive module. The bore includes a standard keyway; custom keyway or spline profiles can be machined on request.<\/p>\n<\/details>\n<details style=\"border:1px solid #ffcc80;border-radius:8px;margin-bottom:12px;overflow:hidden;\">\n<summary style=\"background:#fff8e1;padding:14px 16px;cursor:pointer;font-weight:bold;font-size:15px;color:#e65c00;\">How does the worm gearbox perform in cold storage environments at -20 to -30 deg C?<\/summary>\n<p style=\"padding:14px 16px;font-size:14px;color:#444;line-height:1.8;margin:0;\">Cold storage is one of our most frequently requested AGV environments. Mineral gear oil at -25 deg C can be 100 times more viscous than at operating temperature, causing motor overload protection trips. We specify <strong>PAO synthetic gear oil with a pour point of -55 deg C<\/strong> for all cold storage AGV applications, factory-filled before shipment. Lip seals are specified in FKM for cold temperature flexibility rather than standard NBR, which can harden below -20 deg C and lose sealing effectiveness.<\/p>\n<\/details>\n<details style=\"border:1px solid #ffcc80;border-radius:8px;margin-bottom:12px;overflow:hidden;\">\n<summary style=\"background:#fff8e1;padding:14px 16px;cursor:pointer;font-weight:bold;font-size:15px;color:#e65c00;\">What is the expected service life of a worm gearbox in a 24\/7 warehouse AGV application?<\/summary>\n<p style=\"padding:14px 16px;font-size:14px;color:#444;line-height:1.8;margin:0;\">With correct sizing (SF 1.5 or higher for AGV duty), PAO synthetic lubricant, and IP54+ sealing, our worm gearboxes are designed for a minimum of 20,000 hours of service in continuous-shift AGV operation &#8211; approximately 5 years of three-shift running. The worm wheel bronze is typically the wear-limiting component. Replacement worm wheel and shaft pairs are stocked as service parts with a 10-year availability commitment for all current production frames.<\/p>\n<\/details>\n<details style=\"border:1px solid #ffcc80;border-radius:8px;margin-bottom:12px;overflow:hidden;\">\n<summary style=\"background:#fff8e1;padding:14px 16px;cursor:pointer;font-weight:bold;font-size:15px;color:#e65c00;\">Can you supply the gearbox as part of a complete drive module assembly?<\/summary>\n<p style=\"padding:14px 16px;font-size:14px;color:#444;line-height:1.8;margin:0;\">We specialise in the worm gearbox component and can supply it matched with a motor (gearmotor unit) to your specification.
