GB6069-85 roller chain coupling

GB6069-85Roller chain couplingIt is suitable for all kinds of transmission shafts that mechanically connect two coaxial lines; it is usually used for high and low speed transmissions with frequent starting.The working temperature is -40～+120℃; the nominal torque of transmission is 40～25000N.m.The roller chain coupling has the characteristics of simple structure, easy assembly and disassembly; compact size, reliable work, high efficiency, long life, suitable for various working environments, convenient maintenance, and low cost.The shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J).The type and size of shaft hole and keyway are processed according to the standard GB3852-83 "Coupling shaft column and keyway type and size".The semi-coupling is made of casting, cast steel ZG35Ⅱ, and the shaft hole and keyway are drawn.The chains are all matched with standard products.

The GB6069-85 roller chain coupling has the hardness of steel, and the roller chain coupling has excellent corrosion resistance and environmental protection performance. The GL type roller chain coupling super-machining machine tool can achieve the required accuracy. However, due to the special structure of the roller chain coupling, guide rail, and spindle, this type of machine tool is not only expensive, but also has a small stroke, The disadvantages of low cutting efficiency and long clamping time make it difficult to meet the needs of mass production of larger workpieces.The integral rolling lining has no joints (the thickness of the ETFE lining is 2~5mm), which can withstand various concentrations of acids, alkalis, salts, strong hydrogenating agents, organic compounds and all other strong corrosive chemical media (corrosion resistance and PTFE the same). 　

Roller chain coupling is an ideal product to solve the difficult corrosion problems of high-temperature dilute sulfuric acid, hydrofluoric acid, hydrochloric acid and various organic acids. It is resistant to positive and negative and vacuum, alternating cold and heat, the lining is not affected, and can be solved The delamination problem of PTFE lined sheet equipment is defined as a feature of high-precision processing. In addition to the tolerance range, it also considers the size and batch size of the parts.Maintaining a tolerance of 5μm when machining large quantities of parts, and maintaining a tolerance of 2μm when machining two matching parts, or using a small diameter end mill to process on a machine tool with a positioning accuracy of 0.3μm, etc., all belong to the category of high processing. .In other words, the size of the part and the batch size of the workpiece determine the difficulty of achieving certain specific tolerances.
