Abstract
The utility model is that the special cold and hot temperature difference dismounting geared system of pinion changed by a kind of mammoth mill autogenous tumbling mill, it comprises gear cover, heating tube, adjustment screw rod, cooling shaft cover, carrying roller, metal stool, jack, liquid nitrogen container, liquid gas storage tank, flexible pipe, gear cover divides 2 half, many heating tubes are evenly provided with in cover, heating tube is flexibly connected with adjustment screw rod, adjustment screw rod is spun on gear cover top nut internal fixtion, the jack of holder gear is provided with bottom gear cover, be provided with at gear cover two side plate center and wear axis hole, the side in hole is provided with hollow cooling shaft cover, cooling shaft cover and carrying roller are contained on two plate metal stools, heating tube and cooling shaft cover are all provided with nozzle, heating tube and cooling shaft cover are connected with liquid gas storage tank and liquid nitrogen container with flexible pipe respectively.This cold and hot temperature difference dismounting geared system is simultaneously to gear heating, and to axle cooling, the two temperature difference is to axle when 200 DEG C and gear is for convenience detach or assemble.Have laborsaving, save time, maintenance speed is fast, reduces cost advantages.
Description
Technical field
The utility model relates to a kind of ore dressing plant large-size autogenous mill etc., changes the cold and hot temperature difference dismounting geared system that pinion is special.
Background technology
Current known autogenous tumbling mill pinion shaft, the diameter of axle reaches 250mm, axle and gear interference fit, tradition adopts forcing press dismounting gear in manufactory, very convenient, does not have forcing press in ore dressing plant, adopt wheel puller, because of gear and axle contact surface greatly, artificial cold-drawn goes out gear and extremely requires great effort time-consuming.During new gear dress, adopt and gear entirety on pit furnace is heated to 200 DEG C of temperature, when bore size is slightly larger than the diameter of axle, axle is injected cooling assembling in gear hole complete, exist time-consuming equally.
Summary of the invention
There is time-consuming deficiency to solve autogenous tumbling mill tradition replacing pinion, the purpose of this utility model provides the cold and hot temperature difference dismounting in a kind of laborsaving timesaving geared system.
The utility model adopted technical scheme of dealing with problems is: it comprises gear cover, heating tube, adjustment screw rod, cooling shaft cover, carrying roller, metal stool, jack, liquid nitrogen container, liquid gas storage tank, flexible pipe, gear cover divides 2 half, many heating tubes are evenly provided with in cover, heating tube is flexibly connected with adjustment screw rod, adjustment screw rod is spun on gear cover top nut internal fixtion, the jack of holder gear is provided with bottom gear cover, be provided with at gear cover two side plate center and wear axis hole, the side in hole is provided with hollow cooling shaft cover, cooling shaft cover and carrying roller are contained on two pieces of metal stools, heating tube and cooling shaft cover are all provided with nozzle, heating tube and cooling shaft cover are connected with liquid gas storage tank and liquid nitrogen container with flexible pipe respectively.When tearing gear open, gear shaft is rested on the carrying roller of two pieces of metal stools, two cooling shaft covers are enclosed within the axle of gear cover two side gear two limit, gear is put in gear cover, heating tube position is mixed up with adjustment screw rod, light liquefied gas heating gear, open cooled with liquid nitrogen axle, when gear and axle temperature differ from 200 DEG C, axle just can easily pull out simultaneously.During new gear assembling, gear is put in gear cover, rest on jack supporting plate, mix up heating tube heating gear.Axle pierces into cooling shaft cover, rests on the carrying roller of two plate metal stools, opens cooled with liquid nitrogen axle, and when gear and axle temperature difference are to 200 DEG C, axle inserts cooling in gear hole and installs.Because not needing manually to pull out gear, heating gear with liquefied gas during cogged, selecting a cooled with liquid nitrogen axle very convenient, thus reaching the utility model laborsaving timesaving object.
The beneficial effects of the utility model are, replacing autogenous tumbling mill pinion is laborsaving to save time, and can save cost, shorten maintenance time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Figure is that the utility model embodiment is tearing the schematic diagram of gear open.
In figure 1, metal stool 2, carrying roller 3, cooling shaft cover 4, heating tube 5, gear cover 6, adjustment screw rod 7, liquid nitrogen container 8, flexible pipe 9, jack 10, liquid gas storage tank
Detailed description of the invention
In the embodiment shown in figure, gear cover 5 is divided into 2 half to connect with screw, and gear cover 5 two side plate center is provided with wears axis hole.Be provided with jack 9 bottom gear cover 5, gear cover 5 cylindrical be provided with and arrange nut more, often row has two nuts, and adjustment screw rod 6 is spun on nut and fixes.Evenly be provided with many heating tubes 4 in gear cover 5 to be flexibly connected with adjustment screw rod 6, play the spacing of adjustment heating tube 4 and gear.Heating tube 4 is provided with nozzle, and heating tube 4 flexible pipe 8 is connected with liquid gas storage tank 10.Cooling shaft cover 3 is provided with nozzle and air inlet pipe for open circles ring body.Two cooling shaft covers 3 and two carrying rollers 2 are contained on two pieces of metal stools 1 respectively, and carrying roller 2 can make axle easily movement, and cooling shaft cover 3 flexible pipe 8 is connected with liquid nitrogen container 7.Gear cover 5 is upper and lower is all provided with air vent, helps burning.When tearing gear open, two pieces of metal stools 1 are placed on gear cover 5 two side.Gear shaft pierces into two cooling shaft cover 3 Nei And and rests on carrying roller 2, and gear is put in gear cover 5, mixes up heating tube 4 position and opens liquefied gas and liquid nitrogen, and heating gear and cooling shaft, the temperature difference of gear and axle is to about 200 DEG C, and axle just can easily pull out.During cogged, gear is put gear cover 5 into and is rested on jack 9, axle pierces in two cooling shaft covers 3 and rests on the carrying roller 2 of two pieces of metal stools 1, gear heated simultaneously and select-160 DEG C of liquid nitrogen to cool axle, be easy to the two temperature difference to about 200 DEG C, when gear aperture is greater than the diameter of axle, axle is put in gear hole and cools, because of autogenous tumbling mill pinion shaft, the diameter of axle is large, shrinkage factor is just large, and employing temperature difference dismounting effect is good laborsaving especially to save time.
