A difference in wear can create unequal load and side forces even when the sprocket itself is dimensionally correct. A useful field note for double-single sprockets for two independent chains pairs parallel chain drive with double single sprocket. That keeps the decision tied to the actual chain drive rather than a visual match.<\/p>\n<p >Use the wear evidence to test maintenance is two-chain maintenance: asymmetric polishing, fretting, root impact, or chain climbing should lead to a measurable correction rather than a like-for-like replacement.<\/p>\n<\/section>\n<section id=\"matrix\" style=\"margin:0 0 46px;\">\n<h2 style=\"margin:0 0 18px;color:var(--color-brand) !important;font-size:27px;line-height:1.25;border-left:5px solid var(--color-brand);border-bottom:2px solid var(--color-accent);padding:9px 14px;background:var(--color-neutral);\">\u30a2\u30d7\u30ea\u30b1\u30fc\u30b7\u30e7\u30f3\u30de\u30c8\u30ea\u30c3\u30af\u30b9<\/h2>\n<div style=\"overflow-x:auto;max-width:100%;\">\n<table style=\"width:100%;min-width:680px;border-collapse:collapse;\">\n<caption style=\"text-align:left;font-weight:700;color:var(--color-brand);padding:0 0 10px;\">Double-single sprockets for two independent chains \u2014 field decision matrix<\/caption>\n<thead>\n<tr style=\"background:var(--color-brand);\">\n<th scope=\"col\" style=\"padding:11px 12px;text-align:left;color:white;\">\u8981\u7d20<\/th>\n<th scope=\"col\" style=\"padding:11px 12px;text-align:left;color:white;border-bottom:3px solid var(--color-accent);\">\u78ba\u8a8d\u3059\u3079\u304d\u4e8b\u9805<\/th>\n<th scope=\"col\" style=\"padding:11px 12px;text-align:left;color:white;\">\u30ea\u30ea\u30fc\u30b9\u30ed\u30b8\u30c3\u30af<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:var(--color-surface);\">\n<th scope=\"row\" style=\"padding:10px 12px;text-align:left;\">Double-single is not duplex<\/th>\n<td style=\"padding:10px 12px;\">A double-single sprocket has two tooth rows intended for two independent single-strand chains<\/td>\n<td style=\"padding:10px 12px;\">Correct the system cause linked to double-single is not duplex before fitting new hardware.<\/td>\n<\/tr>\n<tr style=\"background:var(--color-neutral);\">\n<th scope=\"row\" style=\"padding:10px 12px;text-align:left;\">Row spacing follows machine geometry<\/th>\n<td style=\"padding:10px 12px;\">The center distance between the two tooth rows must match the two chain lines or driven components<\/td>\n<td style=\"padding:10px 12px;\">Accept row spacing follows machine geometry when field evidence matches the controlled requirement.<\/td>\n<\/tr>\n<tr style=\"background:var(--color-surface);\">\n<th scope=\"row\" style=\"padding:10px 12px;text-align:left;\">Each chain can carry a different duty<\/th>\n<td style=\"padding:10px 12px;\">Two independent chains may drive separate mechanisms or share load<\/td>\n<td style=\"padding:10px 12px;\">Reconstruct nominal each chain can carry a different duty if wear has obscured the original geometry.<\/td>\n<\/tr>\n<tr style=\"background:var(--color-neutral);\">\n<th scope=\"row\" style=\"padding:10px 12px;text-align:left;\">Tooth phasing can matter<\/th>\n<td style=\"padding:10px 12px;\">When both chains must preserve a timing relationship, specify the angular relationship between tooth rows or keyed shaft references<\/td>\n<td style=\"padding:10px 12px;\">Use the current supplier or machine limit for model-specific tooth phasing can matter.<\/td>\n<\/tr>\n<tr style=\"background:var(--color-surface);\">\n<th scope=\"row\" style=\"padding:10px 12px;text-align:left;\">Maintenance is two-chain maintenance<\/th>\n<td style=\"padding:10px 12px;\">Inspect elongation, lubrication, and tension on each chain independently<\/td>\n<td style=\"padding:10px 12px;\">Record maintenance is two-chain maintenance as a release check before installation or restart.<\/td>\n<\/tr>\n<\/tbody>\n<tfoot>\n<tr style=\"background:var(--color-brand);\">\n<td colspan=\"3\" style=\"padding:11px 12px;color:white;\">\u6700\u7d42\u627f\u8a8d\u306b\u306f\u3001\u6e2c\u5b9a\u3055\u308c\u305f\u6a5f\u68b0\u30c7\u30fc\u30bf\u3068\u6700\u65b0\u306e\u30c1\u30a7\u30fc\u30f3\uff0f\u30b9\u30d7\u30ed\u30b1\u30c3\u30c8\u56f3\u9762\u3092\u4f7f\u7528\u3057\u3066\u304f\u3060\u3055\u3044\u3002\u6a5f\u7a2e\u56fa\u6709\u306e\u5236\u9650\u5024\u306f\u4e92\u63db\u6027\u304c\u3042\u308a\u307e\u305b\u3093\u3002<\/td>\n<\/tr>\n<\/tfoot>\n<\/table>\n<\/div>\n<\/section>\n<section style=\"margin:0 0 46px;\">\n<h2 style=\"margin:0 0 18px;color:var(--color-brand) !important;font-size:27px;line-height:1.25;border-left:5px solid var(--color-brand);border-bottom:2px solid var(--color-accent);padding:9px 14px;background:var(--color-neutral);\">\u4ed5\u69d8\u30c1\u30a7\u30c3\u30af<\/h2>\n<div style=\"display:flex;flex-wrap:wrap;gap:20px;\">\n<div style=\"flex:1 1 230px;min-width:0;border:1px solid gainsboro;border-radius:8px;padding:17px;background:var(--color-neutral);\">\n<p style=\"margin:0 0 6px;color:var(--color-warning);font-size:11px;font-weight:800;letter-spacing:1px;text-transform:uppercase;\">01 \u3092\u907f\u3051\u308b<\/p>\n<p >Ordering a duplex sprocket when the machine actually uses two independent simplex chains.
