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. This prevents a component-level decision from overriding the machine requirement.<\/p>\n<figure class=\"htd-figure\"><img alt=\"\u9996\u5148\u786e\u5b9a\u914d\u5957\u76ae\u5e26\u548c\u6240\u9700\u6bd4\u4f8b\" class=\"htd-tech-image\" decoding=\"async\" loading=\"lazy\" src=\"http:\/\/htdpulley.top\/wp-content\/uploads\/2026\/09\/tech-pitch-1.webp\"\/><\/figure>\n<p>\u5bf9\u4e8e\u66f4\u6362\u9879\u76ee\uff0c\u5728\u786e\u5b9a\u4ea7\u54c1\u76ee\u5f55\u4e2d\u7684\u67d0\u6b3e\u4ea7\u54c1\u662f\u5426\u7b49\u6548\u4e4b\u524d\uff0c\u5e94\u5c06\u6d4b\u91cf\u503c\u4e0e\u5df2\u5b89\u88c5\u7684\u76ae\u5e26\u548c\u673a\u5668\u914d\u7f6e\u8fdb\u884c\u6bd4\u8f83\u3002\u5bf9\u4e8e\u65b0\u9879\u76ee\uff0c\u5e94\u8bb0\u5f55\u8bbe\u8ba1\u4f9d\u636e\uff0c\u4ee5\u4fbf\u540e\u7eed\u7ef4\u62a4\u56e2\u961f\u4e86\u89e3\u8282\u8ddd\u3001\u9f7f\u6570\u548c\u5b89\u88c5\u65b9\u5f0f\u7684\u9009\u62e9\u539f\u56e0\u3002<\/p>\n<\/section>\n<section id=\"geometry\">\n<h2>\u63a7\u5236\u5b89\u88c5\u7684\u5c3a\u5bf8<\/h2>\n<p>\u5373\u4f7f\u76ae\u5e26\u8f6e\u7684\u8282\u8ddd\u548c\u9f7f\u6570\u76f8\u540c\uff0c\u4e5f\u53ef\u80fd\u56e0\u4e3a\u5b54\u5f84\u3001\u8f6e\u6bc2\u3001\u6cd5\u5170\u6216\u8f74\u5411\u4f4d\u7f6e\u4e0d\u540c\u800c\u65e0\u6cd5\u5b89\u88c5\u5230\u673a\u5668\u4e0a\u3002\u6d4b\u91cf\u8f74\u63a5\u53e3\u3001\u76ae\u5e26\u7aef\u9762\u5bbd\u5ea6\u3001\u8f6e\u6bc2\u4e24\u4fa7\u7684\u7a81\u51fa\u90e8\u5206\u4ee5\u53ca\u76ae\u5e26\u7ebf\u76f8\u5bf9\u4e8e\u7a33\u5b9a\u673a\u5668\u57fa\u51c6\u9762\u7684\u4f4d\u7f6e\u3002\u5982\u679c\u4f7f\u7528\u9525\u5f62\u886c\u5957\uff0c\u8bf7\u8bb0\u5f55\u76ae\u5e26\u8f6e\u7cfb\u5217\u548c\u886c\u5957\u4ee3\u7801\u3002\u5982\u679c\u9700\u8981\u7cbe\u52a0\u5de5\u5b54\uff0c\u8bf7\u5728\u56fe\u7eb8\u4e0a\u6807\u660e\u914d\u5408\u65b9\u5f0f\u3001\u952e\u69fd\u4ee5\u53ca\u4efb\u4f55\u56fa\u5b9a\u65b9\u5f0f\u3002<\/p>\n<figure class=\"htd-figure\"><img alt=\"\u6355\u6349\u63a7\u5236\u88c5\u914d\u7684\u6ed1\u8f6e\u51e0\u4f55\u5f62\u72b6\" class=\"htd-tech-image\" decoding=\"async\" loading=\"lazy\" src=\"http:\/\/htdpulley.top\/wp-content\/uploads\/2026\/09\/tech-selection-1.webp\"\/><\/figure>\n<p>\u5bf9\u4e8e\u66f4\u6362\u9879\u76ee\uff0c\u5728\u786e\u5b9a\u4ea7\u54c1\u76ee\u5f55\u4e2d\u7684\u67d0\u6b3e\u4ea7\u54c1\u662f\u5426\u7b49\u6548\u4e4b\u524d\uff0c\u5e94\u5c06\u6d4b\u91cf\u503c\u4e0e\u5df2\u5b89\u88c5\u7684\u76ae\u5e26\u548c\u673a\u5668\u914d\u7f6e\u8fdb\u884c\u6bd4\u8f83\u3002\u5bf9\u4e8e\u65b0\u9879\u76ee\uff0c\u5e94\u8bb0\u5f55\u8bbe\u8ba1\u4f9d\u636e\uff0c\u4ee5\u4fbf\u540e\u7eed\u7ef4\u62a4\u56e2\u961f\u4e86\u89e3\u8282\u8ddd\u3001\u9f7f\u6570\u548c\u5b89\u88c5\u65b9\u5f0f\u7684\u9009\u62e9\u539f\u56e0\u3002<\/p>\n<\/section>\n<section id=\"application\">\n<h2>\u5c5e\u4e8e\u9009\u62e9\u8303\u56f4\u7684\u64cd\u4f5c\u6761\u4ef6<\/h2>\n<p>The same nominal HTD 14M timing pulley selection component can see very different service depending on the machine.

Tooth count changes pitch diameter and can also coincide with changes in body type, hub and material across a catalogue family. The correct comparison therefore stays row-specific after the pitch has been chosen. For a new drive, ratio and center distance must be reviewed together with available diameter and guard clearance.<\/p>\n<p>For a replacement, begin with the mating belt and the installed part. If the belt identity is uncertain, avoid choosing a new family only because the measured pitch appears close. Obtain enough measurements and identification detail to identify the tooth system before comparing product rows.<\/p>\n<\/section>\n<section class=\"htd-soft-panel\">\n<h2>When to Escalate From a Catalogue Row to a Drawing<\/h2>\n<p>Use a drawing-controlled order when the shaft connection, hub position, flange arrangement, material, finish or inspection requirement differs from the normal catalogue configuration. Keep standard HTD tooth geometry explicit on the drawing so the custom machining request does not accidentally obscure the mating-belt requirement.<\/p>\n<p>On mixed-model RFQs, keep every width and tooth count on its own line. A general note such as \u201csame as above\u201d can become unsafe once one model uses a different construction type or bush.<\/p>\n<\/section>\n<section class=\"htd-applied-guide\">\n<h2>Treat 14M Selection as an Envelope and Handling Decision as Well as a Pitch Choice<\/h2>\n<p>The 14M catalogue families include 14M-40, 14M-55, 14M-85, 14M-115 and 14M-170 width-series pages. These larger components deserve a deliberate envelope check because hub, flange, shaft and guard relationships can become as important to installation as the tooth count itself. Use the individual row and construction type rather than extrapolating from a smaller 14M part.<\/p>\n<p>For replacement work, capture the pulley position on the shaft before removal and measure clearances to bearings, guards and adjacent components. If lifting, handling or disassembly space is limited, include that service context with the RFQ. Taper-bush configurations should be tied to the supported bush designation and actual shaft rather than selected from outside diameter.<\/p>\n<p>For new drives, include ratio, center distance, transmitted duty and installation envelope. The website can identify the catalogue family and geometry, while the project data closes the machine-specific decision.<\/p>\n<\/section>\n<section class=\"htd-topic-detail\">\n<h2>Check Handling and Installation Sequence for the Selected 14M Configuration<\/h2>\n<p>As the pulley envelope becomes larger, the installation sequence can matter. Confirm that the selected component can pass through the available guard opening and that there is sufficient space to position it on the shaft without disturbing unrelated components. Where lifting or support is needed, follow the machine owner\u2019s safe handling method rather than improvising from the pulley catalogue.<\/p>\n<p>The purchasing record should also distinguish the catalogue geometry from project-specific requirements. If the machine requires a particular finish, inspection report or shaft fit, add that requirement to the drawing or RFQ. Keep it tied to the exact 14M width series and tooth-count row so a future replacement does not inherit an ambiguous general note.<\/p>\n<\/section>\n<section class=\"htd-applied-guide\">\n<h2>Plan 14M Selection Around the Full Industrial Envelope<\/h2>\n<p>The 14M family covers 14M-40, 14M-55, 14M-85, 14M-115 and 14M-170 width-series pages. These are physically larger components, so shaft size, hub projection, guard clearance, lifting\/handling access and the selected construction type deserve the same attention as pitch and tooth count.<\/p>\n<p>A large pulley can satisfy the belt-side requirements yet still be impractical to install if the hub, bush or removal space is overlooked. Replacement work should therefore include measurements from both shaft ends and the available axial envelope.
