Abstract
The invention relates to a gear inner hole charcoal heating furnace which is high in heating speed and small in gear deformation and can save fuel. The gear inner hole charcoal heating furnace comprises a chassis, a cylinder, an air inlet pipe and a cover board, and is characterized in that: the center of the chassis is connected with the air inlet pipe; a plurality of air outlet holes are distributed on the pipe wall of the air inlet pipe uniformly; the chassis is connected with the cylinder; a plurality of fire spray holes are distributed on the wall of the cylinder uniformly; the cover board passes through the air inlet pipe and is moveably connected with the cylinder; and a plurality of charcoal adding holes are formed in the cover board. The gear inner hole charcoal heating furnace only heats a small-area gear inner hole and does not heat a large-area gear outer edge; the diameter of the gear inner hole is expanded quickly to the required value; a shaft is placed into the gear inner hole and is locked after the gear inner hole is cooled; and the heat assembly is finished. The gear inner hole charcoal heating furnace has the advantages of labor saving, convenience for use and the like.
Description
Technical field
When the present invention relates to a kind of large scale gear, belt pulley, flywheel etc. with the axle interference hot assembly, the isolated plant of heating bore has especially that rate of heating is fast, a fuel saving, gear inner hole charcoal heating furnace that gear shifting quadrant texturing is little.
Background technology
Do not retrieve at present correlation technique, existing large scale gear and axle interference assembling, adopt the pressing machine cold setting in manufactory, needing more in the factory that there is no pressing machine, gear changing all adopts hot charging to join, hot charging is joined needs the gear heating, and the existing whole gear that adopts is in the moving heating of stove turning in, and the heating of bore diameter expand into when larger than the diameter of axle, stopped heating and axle are convenient for assembly, hold axle tightly after the gear naturally cooling.This whole gear heating is joined requirement though can reach hot charging, exists heat-up time long, the expense of taking a lot of work fuel, and the gear internal and external temperature is the same, causes the large deficiency of gear outside deflection.
Summary of the invention
Exist and grow, take a lot of work, take fuel, deficiency that gear shifting quadrant texturing is large heat-up time in order to overcome existing whole gear heating, the purpose of this invention is to provide a kind of rate of heating soon, fuel saving, gear inner hole charcoal heating furnace that gear shifting quadrant texturing is little.
The present invention's technical scheme that adopts of dealing with problems is: it comprises chassis, cylinder, blast pipe, cover plate, connect a blast pipe at center chassis, the blast pipe tube wall is provided with a plurality of uniform air outlet openings, connect a cylinder on the chassis, cylindrical wall is provided with a plurality of uniform fire jetting holes, the cover plate string is crossed blast pipe and is connected with described cylindrical moveable, and cover plate is provided with a plurality of charcoal holes of adding.During use, the charcoal lighted is added the charcoal hole from cover plate fill it up with the cylinder endoporus.Stove is put in the middle of bore, blast pipe and blower fan are connected wind, wind helps charcoal burning through air outlet opening on blast pipe, the flame of charcoal burning, evenly be sprayed onto bore by the fire jetting hole on cylindrical wall and carry out homogeneous heating, until the bore diameter is when larger than the diameter of axle, stopped heating, easily put axle into bore, after naturally cooling, assembling is complete.In the heating of bore Multipoint Uniform, thermo-efficiency is high, and bore is little because of heating-surface area, rate of heating is just fast, and fuel is just economized, and the gear outside is just little because not heating temperature rise, deflection is also just little, thereby reaching the present invention has that rate of heating is fast, fuel saving, purpose that gear shifting quadrant texturing is little.
The invention has the beneficial effects as follows have that rate of heating is fast, fuel saving, gear shifting quadrant texturing be little, also has lower than gas heating cost, simple in structure, easy to use.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Figure is the vertical section structure figure of the embodiment of the present invention.
In figure 1, blast pipe 1-1, air outlet opening 2, cover plate 2-1, add charcoal hole 2-2, sealing cover 3, cylinder 3-1, fire jetting hole 4, chassis
Embodiment
In the embodiment shown in figure, in 4 centers, chassis and blast pipe 1 welding of circle, blast pipe 1 tube wall is provided with a plurality of uniform air outlet opening 1-1.Cylinder 3 use sheet plates are made, and are contained in above the cylindrical on chassis 4, and cylinder 3 barrels are provided with a plurality of uniform fire jetting hole 3-1.Cover plate 2 use iron plates are made disc, and the center is provided with a hole and went here and there blast pipe 1 and be flexibly connected with cylinder 3.Be provided with a plurality of charcoal hole 2-1 that add on cover plate 2, be flexibly connected sealing cover 2-2 on add charcoal hole 2-1, prevent the charcoal burning flame outer spray.Cylinder 3 external diameters are than the little 2-3cm of heating bore, and height is identical with gear.When using stove, to light charcoal fills it up with from adding charcoal hole 2-1, stove is put in the middle of bore again, connect blower fan charcoal burning flame and evenly be sprayed onto the bore homogeneous heating by a plurality of fire jetting hole 3-1, thermo-efficiency is high, only heat the small area bore, does not heat big area gear outside, thus have rate of heating fast, economize charcoal, the little advantage of gear shifting quadrant texturing.The thermal expansion of bore diameter is to set(ting)value, and stopped heating is taken out stove, and the cleaning bore is put axle into bore, cooling after, hold axle tightly, assembling finishes.
Claims (2)
