Description
Technical field
The present invention relates to technical field of transmission, especially relate to a kind of from lowering the temperature gear.
Background technique
Gear in use, must be at suitable temperature, especially should be in lower temperature on the flank of tooth of its engaging tooth, otherwise very easily there is heat seal phenomenon, formative gear directly scraps then.For this reason, gear adopts part more or is all immersed in the mode in lubricant oil, to lubricate the generation that reduces heat seal phenomenon by improvement.Yet in some cases, gear is High Rotation Speed not only, and can not be in lubricant oil.
For this reason, the inventor has developed a kind of cooling gear, this cooling gear comprises core wheel, the outer fringe surface of this core wheel is provided with to the external tooth protruding, and there is teeth groove between adjacent external tooth, described core wheel is provided with at least 1 the first receiving cavity, in this receiving cavity, be equipped with a fan, and this core wheel is provided with the second receiving cavity of sealing, in this second receiving cavity, be provided with battery pack, this fan is electrically connected to this battery pack by switch, simultaneously, on the bottom surface of this teeth groove, have exhaust outlet, this exhaust outlet is communicated to this first receiving cavity by an air channel, and, this first receiving cavity and this second receiving cavity are all sealed by a cover plate, this cover plate is fixed by the screw being screwed onto on this core wheel, and be provided with inlet hole for sealing the cover plate of this first receiving cavity.Like this, the fan energising of this cooling gear and after starting, the wind of generation blows to the flank of tooth of external tooth through air channel, has reduced preferably external tooth temperature, has then avoided preferably the generation of heat seal phenomenon.
Yet this cooling gear must need in use this fan of manual control switch and change in time battery pack, this is comparatively loaded down with trivial details in actual use, very inconvenience.
Summary of the invention
The object of this invention is to provide a kind of gear of certainly lowering the temperature, it has can effectively avoid the generation of heat seal phenomenon, and uses simple feature.
The technical solution adopted in the present invention is: a kind of from lowering the temperature gear, comprise core wheel, the outer fringe surface of this core wheel is provided with to the external tooth protruding, and there is teeth groove between adjacent external tooth, simultaneously, this core wheel is provided with at least 1 the first receiving cavity, in this first receiving cavity, be equipped with a fan, on the bottom surface of this teeth groove, have exhaust outlet, this exhaust outlet is communicated to this first receiving cavity by an air channel, and this core wheel is provided with the second receiving cavity of sealing, and, this first receiving cavity and this second receiving cavity are all sealed by a cover plate, this cover plate is fixed by the screw being screwed onto on this core wheel, and be provided with inlet hole for sealing the cover plate of this first receiving cavity, in described the second receiving cavity, be provided with inductor coil, this fan is connected to this inductor coil by diode electrically, simultaneously, the both sides of this core wheel are provided with magnet.
The advantage that the present invention has is: can effectively avoid the generation of heat seal phenomenon, and use simple.Fan energising from cooling gear of the present invention and after starting, the wind of generation blows to the flank of tooth of external tooth through air channel, has reduced preferably external tooth temperature, has avoided to a certain extent the generation of heat seal phenomenon.Wherein, the magnetic line of force that the required electric energy of this fan is formed by inductor coil septum magnet and producing.That is as long as this gear rotation, this fan must be switched on and be rotated, and regularly changes battery pack and manipulation of switches without artificial, very convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view (part);
Fig. 2 is that sectional view is looked on a left side of Fig. 1;
Fig. 3 is of the present invention for sealing the plan view of the cover plate of the first receiving cavity.
In figure: 10, core wheel; 20, external tooth; 30, teeth groove, 31, exhaust outlet, 32, air channel; 40, the first receiving cavity; 50, fan; 60, the second receiving cavity; 70, inductor coil, 71, diode; 80, magnet; 90, cover plate, 91, inlet hole.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: a kind of gear of certainly lowering the temperature, comprise core wheel 10, the outer fringe surface of this core wheel 10 is provided with to the external tooth 20 protruding, and between adjacent external tooth 20, has teeth groove 30.This core wheel 10 is provided with at least 1 the first receiving cavity 40, is equipped with a fan 50 in this first receiving cavity 40.The second receiving cavity 60 that is also provided with sealing on this core wheel 10, is provided with inductor coil 70 in this second receiving cavity 60.This fan 50 is electrically connected to this inductor coil 70 by diode 71.Meanwhile, the both sides of this core wheel 10 are provided with magnet 80.Such as, this magnet 80 is fixed on applies this on the equipment of the gear of lowering the temperature.That is, after this gear rotation of certainly lowering the temperature, the magnetic line of force that this this magnet 80 of inductor coil 70 cuttings forms and generation current, electric current offers this fan 50 after these diode 71 rectifications, then these fan 50 rotations.On the bottom surface of this teeth groove 30, have exhaust outlet 31, this exhaust outlet 31 is communicated to this first receiving cavity 40 by an air channel 32.Like this, the wind that the fan 50 after startup produces blows out from this exhaust outlet 31 via air channel 32, and external tooth 20 is lowered the temperature, and has effectively avoided the generation of heat seal phenomenon.Further say, this first receiving cavity 40 and this second receiving cavity 60 are all by not shown on a cover plate 90(Fig. 1) sealed, this cover plate 90 is fixed by the screw being screwed onto on this core wheel 10.Like this, be convenient to the installation of this fan 50 and this inductor coil 70.And, for sealing the cover plate 90 of this first receiving cavity 40, be provided with inlet hole 91, like this, guaranteed the normal operation of this fan 50.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
