Customized Plate Center Sprockets Non-Standard Sprocket Wheels For Sale

Non-standard sprocket wheels, also known as custom or unique, refer to sprockets designed and manufactured according to specific requirements that deviate from standard industry specifications. Unlike standard sprocket wheels, which follow established industry standards for tooth profiles, pitch, and other dimensions, non-standard sprocket wheels are tailored to meet unique or specialized applications.Sprockets are furnished in two basic types: Plate Center and Spoked Arm. Plate Centers are generally used on smaller sprockets whose size prohibits the use of spoked arms, and on drives and conveyers which are subjected to frequent shock loads. They are also used when the maximum allowable chain pull is greater than that which Spoked Arm Sprockets can withstand.Both Spoked Arm and Plate Center sprockets are available with splitconstruction. Split construction is often specified for installations when it is desirable or advantageous to mount or remove the sprocket from the shaft without disturbing either the shaft or the bearings. The method now used in mounting a split wheel to the shaft increases holding effectiveness.Split wheels are cast in one piece, machined, and split so that when bolted together the sprocket forms a solid construction. Split wheels are furnished with hubs on one side, hubs offset, or C hubs. Rim lugs are employed when the diameter of the wheel makes them necessary. Since wheels are cast in one piece and then split, it is necessary to give bore size required if ordered in core-to-bore special construction.HUB TYPESSprockets are supplied in various hub types, each one designed for a specific need. The following defines and illustrates each of the basic hub types.Type “A”When a sprocket is described as type “A”, this indicates that there really is no hub which is part of the sprocket wheel. The wheel must be mounted on a flange or hub or other holding device.Type “B”This indicates that the sprocket has a hub extending on one side only from the wheel. This type of hub is generally found on small and intermediate size sprockets.Type “C”These hubs are centrally located, extending an equal distance on both sides of the wheel. This type of hub is the most common type and is generally found on large diameter sprockets.Type “D” OffsetType “D” Offset hubs are the same as type “C” mentioned above, but are slightly off center.Non-standard sprocket wheels are typically manufactured through a custom engineering and manufacturing process. This involves working closely with a sprocket manufacturer or a specialized engineering team to design and produce sprocket wheels that precisely match the desired specifications and performance requirements. The design process may involve CAD (Computer-Aided Design) software to create the sprocket geometry, considering load capacity, speed, alignment, and compatibility with mating components.KEYSEATING, KEYS AND SETSCREWSA single keyseat and one pair of setscrews are furnished as standard on all sprockets, unless otherwise specified. Keys are not furnished as standard, and must be ordered. When keyway and setscrew sizes are not specified, they are supplied in accordance with the table of dimensions headed “STANDARD KEYWAYS AND SETSCREWS”. Standard tolerances for straight and tapered keyways are: width +.002 - .000, depth +.010 - .000. Setscrews are placed over key, and at 90° to the key, unless otherwise specified. Tapered keyways are supplied only when specified. Non-standard keyway sizes are available.

 The manufacturing process for non-standard sprocket wheels may involve specialized machining techniques, such as CNC (Computer Numerical Control) machining or gear cutting, to produce the desired tooth profile and dimensions accurately. Material selection, heat treatment, and surface finishing processes may also be customized based on the specific application requirements and environmental conditions in which the sprocket will operate.
