Description
Technical field
The utility model relates to retarder technical field, particularly relates to a kind of Novel gear speed reducer.
Background technique
At present, traditional transmission device adopts gear transmission or Worm Wheel System, is assemblied in by driving component in casting (or welding) casing.
In traditional multi-level planet gear speed reducer, the transmission shaft of intergrade level planetary gear reducing mechanism does not support, and transmission is stable not, and reliability is not high yet.
Meanwhile, the operating ambient temperature at transmission device place is very high, is generally about 80 DEG C, even higher.Because ambient temperature is high, the lubricant oil in general speed reducer, Sealing etc. lost efficacy at short notice, cause that retarder operating noise is large, transmission efficiency is low, surface spot corrosion too early damages, and then affect the working life of whole retarder.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of Novel gear speed reducer, in guarantee planet-gear speed reducer while intergrade level planetary pinion stability, the amount of heat that the retarder work that can leave in time produces, thus ensure that retarder inner driver normally works, increase the service life.
The Novel gear speed reducer that the utility model provides, comprise decelerator shell and the gear reduction unit being arranged at described decelerator shell inside, described gear reduction unit comprises planet carrier, planet axis and input shaft, described input shaft is three-stage planetary gear reducing gear, and described planet axis surface comprises annular groove.
In a kind of preferred embodiment of the present utility model, described Novel gear speed reducer also comprises motor, described input shaft and described planet axis gears meshing, and described planet axis drives planet carrier to rotate.
In a kind of preferred embodiment of the present utility model, in described input shaft, between the transmission shaft two ends of second level planetary gear reducing mechanism and box body of speed reducer, be equipped with bearing.
In a kind of preferred embodiment of the present utility model, described planet axis comprises multiple radial direction oil hole, and described multiple radial direction oil hole is arranged along described planet axis axial direction array.
Compared to prior art, the Novel gear speed reducer that the utility model provides is equipped with bearing between the transmission shaft two ends and box body of speed reducer of intergrade planetary gear reducing mechanism, planet axis surface arranges annular groove simultaneously, oil can be prolonged groove when driven by motor planet axis rotates and throw away heat radiation, there is lubrication simultaneously, to take away the amount of heat produced in retarder work in time, thus ensure that retarder inner driver normally works, increase the service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the sectional drawing of Novel gear speed reducer one better embodiment that the utility model provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, is the sectional drawing of Novel gear speed reducer one better embodiment that the utility model provides.Described Novel gear speed reducer 1 comprises decelerator shell (not shown) and is arranged at the gear reduction unit 13 of described decelerator shell inside, described gear reduction unit 13 comprises planet carrier 131, planet axis 133 and input shaft 135, described input shaft 135 is three-stage planetary gear reducing gear, does described planet axis 133 surface comprises annular groove 1331 (have two in figure?).
Described Novel gear speed reducer also comprises motor (not shown), and described input shaft 135 and described planet axis 133 gears meshing, described planet axis 133 drives planet carrier 131 to rotate.
Bearing 11 is equipped with between the transmission shaft two ends of second level planetary gear reducing mechanism 1351 and decelerator shell in described input shaft 135.
Described planet axis 133 comprises shoe cream room 1335 and multiple radial direction oil hole 1333, described radial direction oil hole 1333 extends to the radial end face of described planet axis 133 from described shoe cream room 1331, and described multiple radial direction oil hole 1333 is arranged along described planet axis 133 axial direction array.
When input shaft described in driven by motor 135 rotates, with described planet axis 133 common rotation of described input shaft 135 gears meshing, simultaneously, described planet axis 133 drives planet carrier 131 to rotate, oil can be prolonged groove and throw away heat radiation by the annular groove 1331 on described planet axis 133 surface, flow into described shoe cream room 1331 by described radial direction oil hole 1333, and have lubrication.
Compared to prior art, the Novel gear speed reducer that the utility model provides is equipped with bearing between the transmission shaft two ends and box body of speed reducer of intergrade planetary gear reducing mechanism, planet axis surface arranges annular groove simultaneously, oil can be prolonged groove when driven by motor planet axis rotates and throw away heat radiation, there is lubrication simultaneously, to take away the amount of heat produced in retarder work in time, thus ensure that retarder inner driver normally works, increase the service life.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
