Roller chain coupling

The performance of roller chain couplings is better than other structural types of couplings, and is widely used in mechanical engineering, mechanical parts, and couplings.The advantages of roller chain coupling transmission can transmit motion and power when the center distance between the two shafts is far away.It can work under low speed, heavy load and high temperature conditions and dusty conditions.The transmission ratio can be accurate, the transmission power is large, and the force acting on the shaft is small.However, its manufacturing and installation requirements are relatively high.

The roller chain coupling has a simple structure (composed of four pieces), convenient assembly and disassembly, no need to move the connected two shafts during disassembly, compact size, light weight, compensation capability, low requirements for installation accuracy, and long life , Low cost and other advantages, the roller chain coupling should work under the conditions of good lubrication and protective cover.This type of roller chain coupling has 13 specifications. They are suitable for shaft hole diameter d=16-190mm, shaft hole length L=42-352mm, nominal torque T=40-25000m, and allowable speed without cover. It is 200-1400r/min in the case of shell, 900-4500r/min in the case of installing the cover.

Environmental performance of roller chain coupling

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

The 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 acids. It is resistant to positive and negative and vacuum, alternately changing between cold and heat, and the lining is not affected. It can solve the problem of poly One of the defining characteristics of the delamination problem of tetrafluoroethylene lined board equipment is that in addition to the tolerance range, the size and batch size of the parts are also considered.Maintaining a tolerance of 5μm when processing large quantities of parts, 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 tolerances.

滚子链联轴器上链轮齿数一般取12～22范围内偶数齿，若取较少的链轮齿数，则链轮上的作用力增加；若取较多的链轮数，则德国凌斯联轴器补偿能力降低，半联轴器上链轮的分度圆直径dp=(12～13.5) 或dp=(2～3.2)d；罩壳外径DK=(1.15～1.2)dp；半联轴器外径D=(O.7～0.8)dp；半联轴器长度L=（1.9～2.8）d，大转矩时，取小的系数。

The disadvantage is that after the hinge of the chain is worn out, the pitch becomes larger and the joint is disjointed.Installation and maintenance requirements are high.The advantages of gear transmission are: the instantaneous transmission ratio is constant, the stability is high, and the transmission movement is accurate.The range of transmitted power and speed is large.The structure is compact, and a larger transmission ratio can be achieved.Long transmission service life.

Characteristics and application of roller chain coupling

Features: The chain coupling uses a common chain, and it meshes with two side-by-side sprockets with the same number of teeth. Chain couplings of different structure types. The main difference is the use of different chains. Common ones are double-row roller chain couplings. , Single-row roller chain couplings, toothed chain couplings, nylon chain couplings, etc.

Application: It can be used for shaft transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery. It is suitable for high temperature, humidity and dusty working conditions. It is not suitable for high speed, severe impact load and transmission shafts. In the case of directional force, the chain coupling should work under the conditions of good lubrication and a protective cover.
