Description
Technical field
What the present invention relates to is a kind of retarder, is specifically related to a kind of casting machine speed reducer dedicated.
Background technique
At present, traditional transmission device adopts gear transmission or Worm Wheel System, and driving component is assemblied in casting (or welding) casing.But the operating ambient temperature at transmission device place is very high, be generally about 80 DEG C, even higher.Because ambient temperature is high, lubricant oil, Sealing etc. in general speed reducer lost efficacy at short notice, cause speed reducer even whole smelting system cannot work and cause great economic loss.
Summary of the invention
For the deficiency existing in prior art, the present invention seeks to be to provide a kind of casting machine speed reducer dedicated, can under hot environment, run well, thus the normal work of guarantee transmission device.
To achieve these goals, the present invention realizes by the following technical solutions: casting machine is speed reducer dedicated, comprise input shaft, small gear, gearwheel, planar double enveloping worm, worm gear, casing inner panel, output shaft, casing outside plate, heat exchange inner chamber, heat-conducting medium outlet and heat-conducting medium entrance, input shaft is located in casing inner panel, and input shaft the inner is provided with small gear, small gear is meshed with gearwheel, gearwheel is socketed on planar double enveloping worm, planar double enveloping worm is meshed with worm gear, worm gear is connected with output shaft, casing inner panel outer installment has casing outside plate, and be provided with heat exchange inner chamber between casing inner panel and casing outside plate, on heat exchange inner chamber, be provided with heat-conducting medium outlet and heat-conducting medium entrance.
Preferably, the outer end of described input shaft and slinger ring interference fit.
Falling heat-transfer medium in heat exchange cavity of the present invention, and heat-conducting medium is surrounded the reducer arrangement in heat exchange cavity, complete machine speed reducer is moved in heat exchange cavity, and heat-conducting medium injects and discharges from outlet from entrance with certain pressure and speed.Mobile heat-conducting medium is derived working environment radiation in time to the heat producing in the heat of retarder and retarder operation process.Thereby ensure that in retarder, each component all can normally be worked.
The present invention can run well under hot environment, thereby ensures the normal work of transmission device.
Brief description of the drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1, this embodiment is by the following technical solutions: casting machine is speed reducer dedicated, comprise input shaft 1, small gear 2, gearwheel 3, planar double enveloping worm 4, worm gear 5, casing inner panel 6, output shaft 7, casing outside plate 8, heat exchange inner chamber 9, heat-conducting medium outlet 10 and heat-conducting medium entrance 12, input shaft 1 is located in casing inner panel 6, and input shaft 1 the inner is provided with small gear 2, small gear 2 is meshed with gearwheel 3, gearwheel 3 is socketed on planar double enveloping worm 4, planar double enveloping worm 4 is meshed with worm gear 5, worm gear 5 is connected with output shaft 7, casing inner panel 6 outer installment have casing outside plate 8, and be provided with heat exchange inner chamber 9 between casing inner panel 6 and casing outside plate 8, on heat exchange inner chamber 9, be provided with heat-conducting medium outlet 10 and heat-conducting medium entrance 12.
It should be noted that outer end and slinger ring 11 interference fit of described input shaft 1.
This embodiment retarder completes power transmission by input shaft 1, driving gear 2, driven gear 3, worm screw 4, worm gear 5 and output shaft 7, retarder welding casing is made up of casing inner panel 6 and casing outside plate 8, certain interval between casing inner panel 6 and casing outside plate 8.Thereby form heat exchange cavity 9.On heat exchange cavity 9, there are respectively heat-conducting medium outlet 10 and heat-conducting medium entrance 12, heat-conducting medium is full of whole heat exchange cavity 9 by heat-conducting medium entrance 12, can be by heat-conducting medium entrance 12 continuously to the interior filling heat-conductive medium of heat exchange cavity 9 when use, for example water, because specific heat of water holds larger, cheap and user cost is lower.Heat-conducting medium in heat exchange cavity 9 is kept apart the Environmental Conditions of high temperature and speed reducer completely, and the part heat that mobile heat-conducting medium produces the heat of working environment and speed reducer in transmission process is derived in time.For ensureing the sealing of retarder, this retarder specialized designs slinger ring 11, slinger ring 11 adopts interference fit with input shaft 1, when work with input shaft 1 High Rotation Speed, working site splashes under the centrifugal action that water on slinger ring 11 produces at High Rotation Speed and is thrown away, thereby has ensured the reliability of sealing.
If necessary, oil temperature supervisory device can also be installed with oil sump temperature in monitoring retarder.If oil temperature is too high, the speed that can inject by adjusting heat-conducting medium and flow are to keep normal oil sump temperature in retarder.
This embodiment has also adopted bearing capacity large, and the Property of Plane-enveloped Worm Transmission that transmission efficiency is high, to avoid causing lubricant oil to lose efficacy because engagement produces too much heat in transmission process.
This embodiment adopts conductive structure that working environment radiation is derived in time to the heat producing in the heat of retarder and retarder operation process, lubricating oil sump temperature in retarder is significantly reduced, while having ensured work, lubricating oil viscosity is not because oil sump excess Temperature reduces, thereby guarantee the normal operation of speed reducer, avoided causing whole smelting system to stop production because transmission device loses efficacy.
Be more than the description to the embodiment of the present invention, by the above-mentioned explanation to the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to these embodiments' multiple amendment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
