The worm gear reducer must handle this cyclic loading without overheating, while the housing must resist cleaning chemicals, animal fats, urea, and fertiliser spray common in livestock facilities. The self-locking property is particularly useful for vertical mixers with raised mixing bowls, where the auger must hold position when stopped partway through a lift cycle.<\/p>\n<h3 style=\"color:#7a3a0a;font-size:1.1em;margin:18px 0 8px;\">Corrosion &#038; Hygiene Specifications<\/h3>\n<ul style=\"line-height:1.9;\">\n<li><strong>Housing:<\/strong> Wear-resistant cast iron with rust-inhibiting primer and polyurethane topcoat \u2014 resists organic acids in fermented feeds and cleaning detergents.<\/li>\n<li><strong>Seals:<\/strong> Double-lip FKM or NBR shaft seals with separate dust lip \u2014 excludes fine feed particles and chaff dust from gear oil.<\/li>\n<li><strong>Output Shaft:<\/strong> Case-hardened alloy steel; chrome plating optional for exposure to aggressive silage acids.<\/li>\n<li><strong>Fasteners:<\/strong> Zinc-plated or stainless \u2014 prevents rust contamination of feed batches during maintenance near feed areas.<\/li>\n<\/ul>\n<h2 style=\"color:#7a3a0a;font-size:1.5em;margin:28px 0 12px;border-bottom:2px solid #7a3a0a;padding-bottom:6px;\">Technical Specifications<\/h2>\n<div style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;margin:16px 0;\">\n<table style=\"width:100%;border-collapse:collapse;min-width:600px;\">\n<tr>\n<th style=\"padding:10px 14px;background-color:#7a3a0a;color:white;font-weight:bold;text-align:left;border:1px solid #ccc;\">Parameter<\/th>\n<th style=\"padding:10px 14px;background-color:#7a3a0a;color:white;font-weight:bold;text-align:left;border:1px solid #ccc;\">Value<\/th>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Gear Ratio<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">10:1 \u2013 60:1<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">Output Torque<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">Up to 2,500 Nm (standard)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Duty Cycle<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">S3 intermittent; typically 15\u201325% on-time<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">Peak Start Torque<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">2.5\u00d7 rated torque (choked-start capability)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Housing<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Cast iron; anti-rust primer + PU topcoat<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">Input Options<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">IEC B5\/B14; solid shaft for V-belt drive; PTO adapter<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Output Options<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Solid shaft; flange; hollow shaft torque arm<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">IP Rating<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#ffffff;\">IP55 standard (feed\/chaff dust environment)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">Service Factor<\/td>\n<td style=\"padding:9px 14px;border:1px solid #ddd;background:#f5f7fa;\">1.75 (S3 batch mixing)<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<h2 style=\"color:#7a3a0a;font-size:1.5em;margin:28px 0 12px;border-bottom:2px solid #7a3a0a;padding-bottom:6px;\">Compliance &#038; Standards<\/h2>\n<p style=\"line-height:1.8;\">Feed mixer worm gear drives comply with <strong>ISO 9001:2015<\/strong> and carry <strong>CE marking<\/strong>.
