沟槽数
2 active V-grooves define the belt arrangement. Confirm the mating pulley and working belt set rather than changing groove count to fit an available part.
SPA 75-02 is a 2-groove SPA V-belt pulley configuration in the taper-bush family. Its product row lists P 75, O 80.5, construction type 8, taper bush 1108, maximum bore 28, and the letter dimensions E -, F 35, J 44, K 10, L 25, M – and N -. These values belong together. Groove count defines the working belt arrangement, the diameter references identify the pulley geometry used by the drive design, and the bush plus bore information describes the shaft interface.
如需更换,请提供完整的标记、皮带截面、轴和键槽详细信息、数量以及拆卸前拍摄的照片。如需安装新的驱动装置,请提供电机和被驱动转速、所需传动比、安装范围以及任何相关的图纸。如果其中任何一项信息未知,请将其标记为待解答的问题,而不是将其转换为假定的规格。
Start with the complete model identity rather than a diameter-only description. Within the 2-groove family, the construction type and taper-bush designation can change as the diameter range changes. A pulley that looks similar in a photograph can therefore require a different hub arrangement, bush or available axial space.
在所有测量记录和报价中,P 和 O 应分别作为单独的参考编号。如果拆卸的零件没有标记,请准确说明测量内容。现场测量的外径不能自动与图纸上的参考编号互换,即使编号正确但参考编号错误,也可能导致错误的更换。

2 active V-grooves define the belt arrangement. Confirm the mating pulley and working belt set rather than changing groove count to fit an available part.
P 75 and O 80.5 are carried separately. Use the same reference convention in field measurements, drawings and purchase records.
Taper bush 1108 and listed maximum bore 28 describe the model envelope. The RFQ still needs the actual shaft diameter and keyway requirement.
Construction type 8 links this model to a specific hub and rim arrangement. That matters when a guard, bearing support or machine frame limits axial space. It also matters when a maintenance team needs access for bush removal. Do not copy hub dimensions from a neighbouring diameter simply because the groove count is the same.

尺寸符号遵循产品表格的约定。SPA 表格页面不会在这些数值旁边明确标注尺寸单位,因此本页不另行规定单位。当报价依据图纸或现场测量结果时,请注明所需的单位约定。

The taper-bush mounting system connects the pulley hub to the shaft while allowing the bore requirement to be handled separately from the pulley rim. For SPA 75-02, the listed bush designation is 1108. Record the installed bush marking before removal when possible, then state the actual shaft diameter and keyway in the RFQ.
The maximum bore value 28 is a listed model limit, not the ordered bore. Hub position and service access should also be checked. A replacement that matches diameter and bore can still create a guard or removal problem if its construction arrangement changes.
在产品系列层面,SPA锥套皮带轮广泛应用于机床、纺织机械、输送设备以及通用电机到负载的传动装置。应用说明不会改变产品行的内容,而是告知买家需要考虑哪些环境条件:例如启动和停止、连续或间歇运行、环境、防护罩间隙、对准通道和维护程序。
For SPA 75-02, keep the 2-groove arrangement and shaft interface fixed while checking those application conditions. If the machine uses an unusual installation envelope or drawing-controlled requirement, state that difference separately instead of assuming it is part of the standard model.

此流程降低了选到外观正确但皮带轮廓、安装接口或轴向位置发生变化的零件的概率。它还能为下一次维护周期创建可重复使用的设备记录。
Standard model selection begins with the product row above. A custom requirement should identify the changed features explicitly. If a drawing calls for a special bore, keyway, hub location, material, finish, balance or measurable inspection point, list that item as a project requirement rather than presenting it as a universal feature of SPA 75-02.
当双方都使用相同的尺寸符号或图纸标注时,检验最为有效。应明确说明需要检查的内容、验收要求以及适用于样品、首件还是批量生产。这样才能确保报价范围与实际机器风险相符。

Include model SPA 75-02, quantity, belt section, 2-groove arrangement, shaft diameter, keyway or bush information, and the machine type. For replacement work, add photographs taken before disassembly. For new equipment, add the required speed relationship and installation envelope. When a drawing exists, send the latest revision so an old screenshot does not become the accidental controlling document.
标准目录滑轮通常按生产批量最低订货量 (MOQ) 供货,而较大或较高价值的产品则可根据实际订单金额订购。新客户可以按样品价格索取 1-5 件评估样品。混合型号订单可以合并,实际订单金额上限为 1,500 美元。特殊材料或工艺有其自身的最低生产量要求。我们专注于工业和 OEM 供货,而非 1-2 件的零售替换订单。
一份完善的采购记录不仅包含产品名称,还应保留型号、数量、轴接口、图纸版本(如适用)以及任何已批准的项目变更。这些信息能为维护团队提供可靠的起点,而无需他们根据旧的装箱单重新构建驱动系统。
安装过程中,请记录实际安装的衬套或孔径以及对机器所做的任何改动。如果驱动装置之后出现皮带跑偏、异常磨损或反复运动等问题,请在再次更换零件前记录故障情况。重新订购零件时,最好以已确认的技术记录为依据,而不是凭记忆或从货架上寻找外观相似的备件。
当多台机器使用相同的皮带轮时,应将每个设备位置分开记录。直径相近的皮带轮可以使用不同的槽数、衬套或轮毂结构。清晰的设备记录有助于混合型号的采购,因为每个项目都能保持其技术特性,同时还能在商业上进行数量合并。
确认此次采购是直接替换、根据已批准记录重复采购还是全新设计。如果是直接替换,请将已安装的部件与型号和结构类型进行比对。如果是重复采购,请确认自上次订购以来,轴、皮带或机器是否发生过任何改动。如果是全新设计,请将速度关系和安装范围保留在设计记录中,而不是采用替换式的测量流程。
此外,还要确认如何进行皮带轮的安装和拆卸。轴接口可能正确,但由于框架构件或防护罩阻挡了衬套螺钉,导致维修空间受限。记录拆卸过程中任何可能的轴向移动量。如果项目图纸中已明确规定了轮毂位置,则应使用该尺寸,而不是仅凭目测估计机器位置。
最后,明确商业意图。即使零件编号相同,小批量评估样品、混合型号的维护订单和重复生产需求也是不同的采购案例。尽早确定数量和时间,以便技术评审和订单计划能够同步进行。
不。在模型决策中,应考虑沟槽数量、结构类型、衬套和实际轴要求。
不,这是标明的型号限制。请说明实际轴径以及键槽或衬套要求。
标记差异并明确指出项目计划控制哪个引用。不要将差异隐藏在通用替换请求中。
是的,当变更后的特征由图纸或可测量的要求明确定义时。特殊材料或工艺可能会影响最低生产量。
