HTD is a curvilinear synchronous system and the nominal pitch must stay associated with its profile family. Record the driver and driven tooth counts when an existing ratio must be preserved. For a new drive, document the target speed ratio, driver speed and expected load before choosing tooth counts.

Before ordering a new pulley, inspect alignment, shaft and bearing condition, mounting security, belt condition, contamination and the position of the belt relative to the flanges. A visible symptom at the pulley is not by itself proof that the pulley geometry is the root cause.<\/p>\n<p>For replacement work, document the installed condition first. Photograph both pulley faces and the belt path, record the belt marking and tooth count, and note whether the symptom appears under load, on reversal or after warm-up. Those observations make it easier to separate an installation problem from a worn or incorrect component.<\/p>\n<\/section>\n<section class=\"htd-soft-panel\">\n<h2>Turn the Finding Into a Controlled Repair<\/h2>\n<p>If a pulley is replaced, keep the accepted model or drawing revision with the maintenance record. Record any shaft or hub machining performed during the repair so the next replacement does not assume the original catalogue interface still exists. If runout or a dimensional characteristic is functionally critical, define the measurement reference and acceptance value on the repair drawing or purchase requirement.<\/p>\n<p>After installation, verify belt line and the drive condition before the machine returns to normal service. The goal is not simply to fit a new component; it is to restore a traceable and serviceable drive configuration.<\/p>\n<\/section>\n<section class=\"htd-applied-guide\">\n<h2>Inspection Should Preserve the Evidence Needed for the Next Replacement<\/h2>\n<p>A useful inspection routine does more than look for broken teeth. Check the belt line, flange contact, tooth-surface condition, bore or bush security, visible fretting, debris accumulation and any sign that the pulley has moved axially. Compare both sides of the drive where possible because a tracking problem can originate at either pulley or at the shaft supports.<\/p>\n<p>When wear is found, record photographs and measurements before cleaning or disassembly. The goal is to preserve enough context to decide whether the pulley itself is damaged, whether alignment or shaft movement contributed, or whether the belt and pulley family were mismatched. A loose part on a bench cannot reproduce all of that information.<\/p>\n<p>Keep the accepted replacement code, belt identity and any updated drawing with the maintenance record. That turns inspection findings into a repeatable procurement reference instead of a one-time visual judgment.<\/p>\n<\/section>\n<section class=\"htd-topic-detail\">\n<h2>\u0639\u0645\u0644\u064a\u0627\u062a \u0627\u0644\u062a\u062d\u0642\u0642 \u0627\u0644\u062e\u0627\u0635\u0629 \u0628\u0627\u0644\u0645\u0634\u0631\u0648\u0639 \u0648\u0627\u0644\u062a\u064a \u0644\u0627 \u062a\u0632\u0627\u0644 \u0628\u062d\u0627\u062c\u0629 \u0625\u0644\u0649 \u0627\u0644\u062a\u0633\u062c\u064a\u0644<\/h2>\n<p>\u0627\u062d\u062a\u0641\u0638 \u0628\u0628\u064a\u0627\u0646\u0627\u062a \u062a\u0639\u0631\u064a\u0641 \u0627\u0644\u062d\u0632\u0627\u0645\u060c \u0648\u0639\u062f\u062f \u0623\u0633\u0646\u0627\u0646\u0647\u060c \u0648\u0639\u0631\u0636 \u0627\u0644\u062a\u0634\u063a\u064a\u0644\u060c \u0648\u0648\u0627\u062c\u0647\u0629 \u0627\u0644\u0639\u0645\u0648\u062f \u0645\u0639 \u0635\u0641 \u0627\u0644\u0643\u062a\u0627\u0644\u0648\u062c \u0627\u0644\u0645\u062d\u062f\u062f. \u0633\u062c\u0651\u0644 \u0623\u064a \u0645\u062a\u0637\u0644\u0628\u0627\u062a \u062e\u0627\u0635\u0629 \u0628\u0627\u0644\u0645\u0627\u0643\u064a\u0646\u0629 \u0645\u0646 \u062d\u064a\u062b \u0627\u0644\u0645\u0644\u0627\u0621\u0645\u0629 \u0623\u0648 \u0627\u0644\u062a\u0634\u0637\u064a\u0628 \u0623\u0648 \u0627\u0644\u0641\u062d\u0635 \u0641\u064a \u0637\u0644\u0628 \u0639\u0631\u0636 \u0627\u0644\u0623\u0633\u0639\u0627\u0631 \u0623\u0648 \u0627\u0644\u0631\u0633\u0645\u060c \u0628\u062f\u0644\u0627\u064b \u0645\u0646 \u062a\u062d\u0648\u064a\u0644\u0647\u0627 \u0625\u0644\u0649 \u0645\u0637\u0627\u0644\u0628\u0629 \u0639\u0627\u0645\u0629 \u0644\u062c\u0645\u064a\u0639 \u0645\u0646\u062a\u062c\u0627\u062a \u0627\u0644\u0645\u062c\u0645\u0648\u0639\u0629.<\/p>\n<p>\u0641\u064a \u0623\u0639\u0645\u0627\u0644 \u0627\u0644\u0627\u0633\u062a\u0628\u062f\u0627\u0644\u060c \u062a\u062d\u0627\u0641\u0638 \u0627\u0644\u0635\u0648\u0631 \u0648\u0627\u0644\u0642\u064a\u0627\u0633\u0627\u062a \u0627\u0644\u062a\u064a \u062a\u064f\u0624\u062e\u0630 \u0642\u0628\u0644 \u0627\u0644\u0641\u0643 \u0639\u0644\u0649 \u0645\u0648\u0636\u0639 \u062e\u0637 \u0627\u0644\u062d\u0632\u0627\u0645\u060c \u0648\u0627\u062a\u062c\u0627\u0647 \u0627\u0644\u0645\u062d\u0648\u0631\u060c \u0648\u0627\u0644\u0645\u0633\u0627\u0641\u0627\u062a \u0627\u0644\u0645\u062c\u0627\u0648\u0631\u0629. \u064a\u062c\u0628 \u062a\u0645\u064a\u064a\u0632 \u0627\u0644\u0642\u064a\u0627\u0633\u0627\u062a \u0627\u0644\u0645\u064a\u062f\u0627\u0646\u064a\u0629 \u0627\u0644\u0645\u0628\u0627\u0634\u0631\u0629 \u0628\u0634\u0643\u0644 \u0645\u0646\u0641\u0635\u0644 \u0639\u0646 \u0642\u064a\u0645 \u0627\u0644\u0643\u062a\u0627\u0644\u0648\u062c \u062d\u062a\u0649 \u0644\u0627 \u062a\u0646\u062a\u0642\u0644 \u0622\u062b\u0627\u0631 \u0627\u0644\u062a\u0622\u0643\u0644 \u0623\u0648 \u0627\u0644\u062a\u0644\u0641 \u0625\u0644\u0649 \u0627\u0644\u0645\u0643\u0648\u0646 \u0627\u0644\u062c\u062f\u064a\u062f.<\/p>\n<\/section>\n<section class=\"htd-applied-guide\">\n<h2>Inspect the Drive in a Sequence That Preserves Useful Clues<\/h2>\n<p>Routine inspection should look at the belt, pulley teeth, flanges, hub or bush, shaft support and surrounding contamination as one drive system. Before cleaning, note belt dust, polished areas, flange rubbing, looseness or movement at the shaft interface. These observations can explain whether wear is caused by the component, alignment or another machine condition.<\/p>\n<p>Avoid replacing parts solely because their surfaces look different from a new component. Compare wear with machine symptoms and measurements.
