QI C HANGZHOU OCEAN INDUSTRY CO., LTD. CM, CW HUBS There are two kinds of bores for CM hubs: the pilot bore (can be reproduced into different types of bores, e.g. split bore, hex bore and squate bore,etc.),and finished bore. CW hubs are paired with BTL taper bores. After matching the hubs with the BTL taper bushings,they can meet the requirements for various bore diameters. COMBINATION BETWEEN HUBS AND PLATE WHEELS There are two kinds of methods to combine CM/CW hubs with plate wheels. Either by welding or using the riveted lap joint. to meet the thicknees of the largest pitch. imension "G" can...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Combination sprokets in rivet joint can be made with simple equipment (bench drill machine) and tools (relevant drill and tap). After simple processes (drlling and tapping holes), combination sprockets of different specifications and with different usages can be made so they can meet all kinds of assembling condlitions. Using finished bore hubs or taper bore hubs, other machining processes can be avoided. They have characteristics of high precision; They are unshaped with low producing cost and are easy to incorporate onto exiting equiment. B type sprockets...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. 3. To tap the screw hole to the demanded depth, use the manual method if necessary. 4. Using the relevant hexagon wrench to tighten all screws in turns and after tightening screw safely, calcic can be used to prevent corrosion and dust. INSTRUCTION FOR RIVET JOINT 1. To combine the re evant hub and sprocket together, the number of set screws can be selected according to the design equir-ement (check with data list), and make the punching marks at the joint of the sprockets and hubs. Please notice the equal spacing requirement. There is no need to be extremely...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Easy install HubsOPERATION INSTRUCTION ABOUT SM, SW HUBS TAPER OF SM/SW HUBS SM/SW hubs are of multi usages when combined with plate wheels by fixing bolts into the flanges. The flange holes of hubs are corresponded with the flange holes of the plate wheels.These kinds of hubs are applicable for plate wheels in medium or large pitch or with large teeth numbers. (Plate wheels with small teeth numbers or small pitch can not use SM/SW hubs due to the limitation of root diameters). SM hubs are with plain bore (pilot bore or finish bore)and SW hubs are paired...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Easy install Hubs TABLE FOR SB DIMENSION USED WITH SM/SW HUBS Degree 12.9 high strength bolts should be adopted for SM/SW hubs. The sizes and quantities can fully support the sprockets when they are in the largest power transmission; very reliable and safe. If the plate wheels or hubs are ruined, just remove the damages parts. This can save time and money on maintenance. TABLE FOR BOLT DIMENSION When the flange of the plate wheel is machined ,the benter line of the teeth must be kept in line with a hole of the flange, then make a mark. When the keyway of...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. DETAIL LIST OF KEYWAYS, SET SCREWS FOR STANDARD BORE Finished bore connection hubs tow typer: CM,SM PILOT BORE HUBS Can provide pilot bore hubs for different assemblies in order for the customer to reproduce the bore according to their special needs, such as spline bores, square bores, hex bores and other special types of bores. CM-D/DS These are all suitable for hubs with finished bores. All the dimensions listed for keyways are also available for bushings (not including shallow keyways).

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Easy install Hubs r\ Taper Bushing Bores CW and SW Hubs using BTL Bushings for Combinatory Sprockets r\ 1. Taper hubs while using BTL bushings are specially Combinatory Sprockets. There are two kinds of taper hubs: CW and SW. To use the relative type of BTL bushings without remachining, all your inner bore dimensional requirements can be met. 2. CW taper hubs are suitable for smaller diameter Combinatory Sprockets. After welding and riveting with plate wheels, the complete Combinatory Sprockets can meet all the functional requirements. 3. SW taper hubs are...

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. Weld-on Sprockets CMD and SMD are the special Hubs for the Combinatory Sprockets which use the Standard Duplex Chains. We have stock for CMD Hubs with both pilot bores and bores but we only supply finished bore for SMD Hubs. For CMD Hubs, riveting is applied to form Duplex Sprockets and for SMD hubs we use bolts to form duplex sprockets. Riveting with screws are suitable for smaller diameter Bolts are suitable for larger diameter combinatory combinatory sprockets. sprockets.

QI C HANGZHOU OCEAN INDUSTRY CO., LTD. When riveting the plate wheels on both sides of the hubs, the rivet holes should be interlaced. The method of processing rivets is the same as when they are processed for simplex sprockets. Dimensions for Processing Rivet Holes. Contract for Hubs and Rivets . The above two tables list the dimensions of the combinatory sprockets of different pitches when they are processed for riveting purposes and also the dimensions of the rivets used with different size hubs. When choosing the rivets, our suggestion is the bigger the better to ensure the strength if only...

HANGZHOU OCEAN INDUSTRY CO., LTD. When driving wheels begin with more number of teeth, the transmission is the state of increasing speed, otherwise when driving wheels begin with less number of teeth, they are in the state of reducing speed. DS Sprockets can be formed from pitches 1/2’’ to 1 1/4 ’’ within 60 numbers of teeth. The combination can be made freely to form both equal-speed and unequal speed DS Sprockets. The only way to connect CMDS hubs with plate wheels is riveting by bolts. The process of connecting the holes is the same as CMD hubs. Combinatory equal-speed sprockets can be formed...
