The roller chain coupling utilizes a common chain and meshes with two parallel sprockets with the same number of teeth. The main difference between roller chain couplings of different structural types is the use of different chains, commonly including double row roller chain couplings, single row roller chain couplings, toothed chain couplings, nylon chain couplings, etc
The roller chain coupling has the advantages of simple structure (composed of four parts), easy assembly and disassembly, no need to move the two connected shafts during disassembly, compact size, light weight, compensation ability, low requirements for installation accuracy, excellent operation, long service life, and low cost. The roller chain coupling should work under good lubrication and protective cover conditions. This type of roller chain coupling has 13 specifications, which are suitable for shaft hole diameter d=16-190mm, shaft hole length L=42-352mm, nominal torque T=40-25000m, allowable speed without casing=200-1400r. min, and with casing installed=900-4500r. min
Performance Introduction of Roller Chain Couplings:
Roller chain couplings have the hardness of steel, excellent performance stability, and environmental performance of roller chain couplings.
. The GLF roller chain coupling ultra precision machining machine can achieve the required accuracy, but due to the special structure of the roller chain coupling, guide rail, and spindle in ultra precision machining, this type of machine is not only expensive, but also has disadvantages such as small stroke, low cutting efficiency, and long clamping time, making it difficult to meet the needs of large-scale production of large-sized workpieces. The overall rolling lining has no seams (ETFE lining layer thickness of 2-5mm) and can withstand various concentrations of acids, alkalis, salts, strong hydrogenating agents, organic compounds (based on actual reports), and all other highly corrosive chemical media (with the same performance stability as polytetrafluoroethylene)Roller chain couplings are ideal products for solving difficult corrosion problems such as high temperature dilute sulfuric acid, hydrofluoric acid, hydrochloric acid, and various organic (based on actual reports) acids. They are resistant to positive and negative and vacuum conditions, with alternating cold and hot changes, and the lining layer is not affected. They can solve the delamination problem of PTFE lining plate equipment. One characteristic of processing is that in addition to the tolerance range, part size and batch size are also considered. Maintain 5% when processing large quantities of parts μ The tolerance of m is maintained at 2 when machining two parts that fit each other μ Tolerance of m, or use a small diameter end mill with a positioning accuracy of 0.3 μ Processing on the machine tool of m belongs to the category of high precision machining. That is to say, the size of parts and the batch size of workpieces determine the difficulty of achieving certain specific tolerances
Application of Roller Chain Couplings:
Roller chain couplings can be used for shaft transmission in textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical and other machinery. They are suitable for high temperature, humidity, and dusty working conditions, and are not suitable for high-speed, severe impact loads, and transmission of axial forces. Chain couplings should work under good lubrication and protective covers.
