Abstract
The utility model discloses a split sprocket set which relates to the field of mechanical transmission. The split sprocket set comprises a sprocket shaft, supporting wheels and a guide sprocket, wherein the supporting wheels and the guide sprocket are arranged on the sprocket shaft. According to the split sprocket set, the resistance of a switching system of a coke oven reversing machine is reduced, the production efficiency is improved, and the cost is saved.
Description
Technical field
The utility model belongs to mechanical transmission fields, relates to a kind of split type chain wheel set.
Background technology
Reversing machine is one of key equipment of coke oven, is responsible for carrying out in per 20 minutes coal gas and waste gas exchange, makes coke oven temperature uniform and stable.As if the health that coke oven is likened to the people, reversing machine is exactly the heart of this health so, and reversing machine will cause damage to coke oven itself after hindering shutdown for some reason, can have influence on the life-span of coke oven when serious, so the steady running of reversing machine is most important for coke oven.
In the coke oven commutation process, reversing machine control hydraulic ram traction exchange tie rod, the switching equipment such as waste gas thallium, air gate and coal gas exchange rotary plug that drive heating system are finished the exchange of coal gas, air and waste gas air flow line.The exchange tie rod is connected with air gate with the waste gas thallium by chain, in exchange process, exchanges tie rod and spurs chain under the guide effect of jockey sprocket, waste gas thallium and air gate are mentioned or puts down.
During the waste gas exchange, tie rod is mobile under oil cylinder drives, and the waste gas thallium of upstream upwards is raised by the next the beginning, and the waste gas thallium of downdraft is put down downwards by upper beginning; When the waste gas thallium of sending down abnormally ascending stream is fallen instantly, this process has only been finished about 80% of whole cylinder stroke, in this process, because it is identical with two loads to the position that descend (waste gas thallium) to rise, both direction is opposite, the identical power of loading is cancelled each other, and the tie rod resistance in this process is very little, can ignore; The thallium bar that rises is in remaining about 20% stroke moving process, because the thallium bar that descends cuts out fully, the load of tie rod is the load of remaining rising thallium bar only.Therefore exchange latter stage at waste gas, the load of exchange tie rod can increase suddenly, this load is close on the jockey sprocket tie rod, and jockey sprocket is subjected to the frictional force effect of tie rod and chain simultaneously, and is different in the rotation number of turns of tie rod reactive force and chain force lower sprocket.At this moment, have the hard grind phenomenon between tie rod, sprocket wheel and chain, the degree of this hard grind is again along with the wearing and tearing of sprocket wheel increase.
Because the existence of above-mentioned hard grind phenomenon, coke oven are frequently stopped in exchange process, all cause very big influence for production, on-the-spot environmental protection and the body of heater health of coke oven.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of exchange system resistance that reduces the coke oven reversing machine, avoids reversing machine to shut down, and avoids a kind of split type chain wheel set that influences coke oven production because shutting down, pollutes site environment and damage body of heater.
For achieving the above object, the utility model has adopted following technical proposal: a kind of split type chain wheel set is characterized in that: comprise sprocket shaft, and supporting-point roller, jockey sprocket, supporting-point roller and jockey sprocket are installed on the sprocket shaft.
Described jockey sprocket external diameter is less than the supporting-point roller external diameter.
Described supporting-point roller has one, and supporting-point roller is installed in jockey sprocket one side, and supporting-point roller and jockey sprocket are coaxial.
Described supporting-point roller has two, and supporting-point roller is installed in the jockey sprocket both sides, and supporting-point roller and jockey sprocket are coaxial.
The beneficial effects of the utility model: after adopting split type chain wheel set, the exchange system resistance reduces greatly, has eliminated because of exchange system resistance reason reversing machine machine halt trouble, makes coke oven heating system steady running.As calculated, volume increase in every month can be created and imitate nearly 800,000 yuan, reduces environmental protection and drops into 40,000 yuan; Split type chain wheel set can realize support braces and the effect of the chain that leads simultaneously, has avoided the generation of hard grind phenomenon, reduces sprocket wheel, chain damage, saves the expense of changing sprocket wheel and chain generation.As calculated, can reduce about 6000 yuan of recondition expense in every month; Can improve the coke oven technic index, by statistics, coke oven key temperatures index horizontally-arranged temperature factor can improve 2%, and the crucial production operation index coke pushing of coke oven overall coefficient can improve 9%.
