Speed ratings range up to 7,600 RPM for certain sleeve coupling models, and torque capacities extend to 312 in-lb for two-piece inserts. Materials used include EPDM for inserts and various metals for hubs and flanges, with components often rated for specific horsepower levels (e.g., 0.3 hp to 1.8 hp) depending on spider material such as Buna-N or Hytrel. The brand's product families cover general-purpose straight jaw couplings (L099, L100 sizes), tire coupling hubs with angular misalignment capability up to 4°, and sleeve coupling systems with spacer hubs and flanges for extended shaft separations. TB WOOD'S components are specified by coupling size, outside diameter, and overall length, making them suitable for integration into existing drive systems. 3G Electric stocks over 377 SKUs of TB WOOD'S couplings and power transmission parts, including hubs, flanges, inserts, and spacer components. This inventory supports global procurement for plant engineers and maintenance managers who require standardized, interchangeable coupling solutions for pumps, conveyors, compressors, and other rotating equipment. The selection covers both inch and metric systems, with plain and finished bore options to accommodate various shaft diameters. 3G Electric provides logistics support for these components, enabling consistent supply for maintenance, repair, and operations (MRO) needs as well as new installations. The TB WOOD'S line is recognized for its dimensional consistency and adherence to established coupling standards, which simplifies replacement and reduces downtime in industrial settings.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang TB WOODS dari 3G Electric.

What types of couplings does TB WOOD'S manufacture?

TB WOOD'S manufactures sleeve couplings, tire couplings, and jaw couplings. Sleeve couplings include components like finished bore close-coupled flanges, two-piece inserts with retaining rings, spacer hubs, and spacer flanges. Tire couplings feature hubs designed for angular misalignment up to 4°. Jaw couplings are general-purpose straight jaw hubs available in metric sizes such as L099 and L100. Each coupling type is offered in multiple sizes and bore configurations to suit different shaft diameters and power transmission requirements.

What are the key specifications to consider when selecting a TB WOOD'S sleeve coupling flange?

When selecting a TB WOOD'S sleeve coupling flange, key specifications include coupling size (e.g., 4, 5, 6, 11), maximum RPM rating (e.g., 3,600 to 7,600 RPM), outside diameter (e.g., 2.5 to 8.625 inches), bore type (plain or finished, round keyed or round), and dimensional system (inch or metric). For example, model 4J78 is a finished bore close-coupled flange with a 4 coupling size, 7,600 RPM max speed, and 2.5-inch outside diameter. These parameters ensure compatibility with the mating hub and shaft.

How does TB WOOD'S tire coupling hub accommodate misalignment?

TB WOOD'S tire coupling hubs, such as model WE2H78, are designed to accommodate up to 4° of angular misalignment. This is achieved through the flexible tire element that connects the hubs, allowing for angular, parallel, and axial misalignment while dampening vibration. The hub itself is a plain bore component rated for specific horsepower (e.g., 0.3 hp) and maximum speed (e.g., 7,500 RPM). This design makes tire couplings suitable for applications where shaft alignment is not perfect.

What materials are used in TB WOOD'S coupling inserts?

TB WOOD'S coupling inserts are available in materials such as EPDM (ethylene propylene diene monomer) and Buna-N (nitrile rubber). For example, the two-piece sleeve coupling insert (model 5) uses EPDM, while jaw coupling hubs may be paired with Buna-N or Hytrel spiders. Material selection affects torque capacity, temperature range, and chemical resistance. EPDM offers good resistance to heat and weathering, while Buna-N provides oil and fuel resistance. Hytrel is a polyester elastomer with higher strength and durability.

Can TB WOOD'S couplings be used with metric shaft sizes?

Yes, TB WOOD'S offers couplings in metric dimensions. For example, the jaw coupling hubs L09925MM and L10022MM have outside diameters of 64 mm and overall lengths of 73 mm and 89 mm, respectively. These metric hubs are designed for general-purpose straight jaw applications and are rated for specific horsepower levels depending on the spider material. The availability of metric sizes allows integration into equipment using ISO-standard shafts.

What is the purpose of a spacer hub and flange in TB WOOD'S sleeve coupling systems?

TB WOOD'S spacer hubs and flanges, such as models 6SCHMPB (spacer hub) and 6SC44 (spacer flange), are used to extend the distance between coupled shafts. This allows for easier maintenance access to equipment like pumps or motors without disassembling the entire coupling. The spacer hub has a plain bore and is sized by coupling size (e.g., 6) and outside diameter (e.g., 2.5 inches for the hub, 4 inches for the flange). Maximum speed ratings (e.g., 6,000 RPM) ensure safe operation at extended shaft separations.
