HTD 14M-40 Taper Bush Timing Pulley Configuration Overview
14M-40 HTD Timing Pulley is a 14 mm pitch synchronous pulley family with a nominal belt-face reference of 40 in the catalogue naming system. This page treats the series as a configurable industrial component rather than a single fixed SKU. Tooth count changes pulley diameter and may also change hub, flange, material or mounting details, so the order must be tied to a specific catalogue row or an approved drawing.
采购时，首先要确定完整的皮带型号，并确认配套皮带是否采用相同的 HTD 14M 齿形。仅凭节距并不能保证所有曲线皮带系列都能安全互换。确认齿形后，选择齿数和工作宽度，然后检查轴接口、轮毂凸出部分、法兰布置和可用材料。此步骤可减少常见的仅匹配外径而忽略齿形或安装几何形状的更换错误。
The taper-bush mounting shown for this family is intended for positive synchronous power transmission. Typical enquiries come from larger industrial drives, textile/paper machinery and heavy synchronous transmission. Actual suitability depends on speed, transmitted load, center distance, belt construction, alignment, environment and shaft support. Those duty inputs should be supplied for a new drive or when an existing machine has recurring belt-tracking or wear problems.
14M-40 Construction and Shaft Interface
14M-40 belongs to the 14M HTD family and this page covers taper-bush mounting. The catalogue table on this page spans 28–192 teeth. Construction codes visible in the table include 18F, 19F, 19, 20. Use the exact product code with the tooth count because the hub/flange arrangement can change inside one width series.
宽度代码 40 本产品目录仅用于识别该系列产品；它不能替代对配套皮带标记和尺寸图的检查。进行更换作业时，请保留已安装的皮带线，并在确定使用齿形正确的皮带排作为机械替代品之前，测量轴侧几何形状。
Read the 14M-40 Dimension View Before the Table
尺寸标注视图解释了 Dp、De、Df、Dm、Di、F、L 等符号以及孔径相关字段与施工图之间的关系。请将图纸和同一产品行一起使用；不要仅仅因为节距和齿数匹配就从其他施工类型中转移尺寸。
For 14M-40, record the values that control installation—working face, hub projection, flange envelope and shaft connection—against a stable machine datum. If a finished bore, keyway or tolerance is not defined by the catalogue row, add it on the RFQ or controlled drawing instead of assuming a universal value.
Bush selection: this 14M-40 table includes bush references such as 2012, 2517, 3020. The bush reference changes with the product row; confirm the exact tooth count and shaft diameter rather than assuming one bush covers the whole series.

Where the 14M-40 Family Fits
14M-40 is part of the 14M family used for larger HTD drive envelopes where hub, flange, shaft interface, mass and service access become increasingly important to installation planning. Application suitability is not determined by pitch alone. A new drive still needs the required speed relationship, load or torque basis, center distance, environment and service conditions before the pulley row can be finalized.
更换皮带时，最安全的出发点是保持现有皮带/型材的规格和齿数不变。改变齿数会改变节圆直径和传动比，而改变安装结构则可能改变皮带的走向或影响拆卸。
Material and Construction Choices for 14M-40
Use the material and construction shown for the exact 14M-40 product code or approved drawing. Do not identify pulley material from color, surface appearance or a photograph. Where a project requests a different material, finish, hub, flange or shaft feature, treat that as a custom requirement and review its effect on dimensions and inspection before quotation.
在28至192齿的范围内，结构代码可能有所不同。正是由于这种差异，产品代码、齿数和结构视图才应在订单记录中保持一致。
Installation Checks for 14M-40
Before installation, compare the new pulley with the released 14M-40 row or drawing. Verify the shaft connection, axial position, flange condition and belt line before tension is applied. The belt should enter the pulley without being forced sideways by a misaligned shaft, displaced hub or incorrect spacer arrangement.
组装完成后，检查对实际机器至关重要的特性——安装牢固性、对准情况、自由旋转、皮带跟踪以及图纸规定的任何跳动或轴向位置。如果设备图纸或订单图纸另有规定，请勿采用通用公差。
订购、样品和商业计划
最低订购量根据产品类型、生产工艺和订单总金额而定。标准目录零件通常遵循最低生产数量要求。
新客户在配置和生产路线合适时可索取1-5件样品。样品价格另计。
不同型号的滑轮可以合并订购。混合型号订单的通常规划点是总订单金额约为 1500 美元。
仅可考虑工程验证或合格的付费样品要求，而不可作为零售订单；单价也相应较高。
标准件：通常需要 10-25 个工作日。定制组件：通常需要 20-45 个工作日。项目组装或相关设备：45-120 个工作日（如适用）。最终交货时间将在图纸、材料和数量审核后确认。
EXW、FOB、CIF 和 DAP 是常见的贸易条款。FCA、CFR、CPT、CIP 和 DDP 可根据具体的货物和目的地进行协商。
How to Prepare an RFQ for 14M-40
请提供完整的皮带标记、所需齿数、皮带宽度、轴径及配合方式、安装方法、数量和目的地。如果轮毂凸出部分、法兰几何形状、键槽、表面处理或检验标准不符合标准，请提供尺寸图或清晰的替换件照片。如果您要更换的是旧款皮带轮，请提供正面、背面和侧面的尺寸，而不仅仅依赖于一个外径值。
14M-40 Frequently Asked Questions
Is every 14M-40 pulley interchangeable?
不。系列代码缩小了节距和宽度范围，但齿数、结构类型、孔径或衬套、轮毂尺寸、法兰布置和材料可能有所不同。请确认具体的产品目录行或图纸。
您能根据现有的滑轮报价吗？
是的，前提是提供的替换信息足够完整。请提供皮带标记、齿数、端面宽度、轴的详细信息以及正反两面的尺寸。对于非标准几何形状，最好提供图纸。
可以少量供应吗？
对于合格的工程验证，可考虑提供少量付费样品。通常的销售模式是工业生产供货，而非单件或两件零售采购。
申请时需要提交哪些文件？
在询价阶段，需要提供州政府要求的尺寸检验、材料文件、标记或订单特定合规记录，以便在生产前确认可用性和范围。
