Description
Technical field:
The utility model relates to the technical field of planetary reducer, more specifically to a kind of load balancing structure of planetary reduction gear transmission.
Background technique:
The planet of planetary reducer is as the term suggests be exactly around Stellar rotation, therefore planetary reducer is exactly the retarder rotated around a sun gear by three planet wheels, it is a kind of velocity transducer utilizing gear, the winding number of motor is decelerated to desired winding number, and obtains the mechanism of larger torque.And as a planetary gear speed reducing mechanism, adopt three planet wheels, also three planet wheels are checked simultaneously during strength check, that is during Theoretical Design, load is evenly distributed on three planet wheels, but in actual production process, gear, casing manufacture can produce error, add the error in assembly process.There will be load uneven distribution on three planet wheels during the running of retarder, serious meeting causes broken teeth, affects operating life.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of load balancing structure of planetary reduction gear transmission is provided, the linkage structure of its rectification ring gear, floating structure is changed into from original structure that fixes, ring gear can regulate automatically, three planetary pinions are all carried, thus ensures the working life of its planetary reducer.
Technology solution of the present utility model is as follows:
A load balancing structure for planetary reduction gear transmission, comprises ring gear, and be plugged with the gear fixed tray of convex shape in ring gear, gear fixed tray is bolted on reduction case, and against there being snap ring on the step surface of gear fixed tray, snap ring holding is on ring gear; The outer wall of gear fixed tray lower end forms gear ring, together with the gear ring of gear fixed tray lower end is meshed with the tooth of ring gear, the step surface of gear fixed tray to the distance of gear fixed tray upper-end surface is greater than the distance of step surface to reduction-gear housing side end face of ring gear of gear fixed tray.
A sun gear and multiple planetary pinion is provided with in described ring gear 1, sun gear, planetary pinion, ring gear mesh together successively, planetary pinion annular is evenly distributed between sun gear and ring gear, planetary pinion is fixed on planet carrier, planet carrier is fixedly connected on output shaft, output shaft is by bearing hinge connection on reduction case, and sun gear is fixedly connected on input shaft, input shaft by bearing hinge connection on reduction case.
Described gear fixed tray is provided with multiple bolt, and bolt annular is evenly distributed on gear fixed tray.
The beneficial effects of the utility model are:
1, it is by the means of fixation of rectification ring gear, makes ring gear have floating structure, thus the change of load in planetary pinion motion, ring gear realizes automatically regulating, and three planetary pinions is all carried, thus ensures the working life of its planetary reducer.
2, the annular gear structure of its employing is without the need to processing the structure of ring gear and reduction-gear housing mates, thus greatly simplifies in technique, gear shaping machine can be utilized to process multiple ring gear together simultaneously, substantially increase manufacturing efficiency.
Accompanying drawing illustrates:
Fig. 1 is the transmission principle schematic diagram of existing planetary reducer;
Fig. 2 is structural representation of the present utility model.
In figure: 1, ring gear; 2, gear fixed tray; 3, snap ring; 4, bolt; 5, reduction case; 6, planetary pinion; 7, sun gear; 8, planet carrier.
Embodiment:
Embodiment: see shown in Fig. 1,2, a kind of load balancing structure of planetary reduction gear transmission, comprise ring gear 1, the gear fixed tray 2 of convex shape is plugged with in ring gear 1, gear fixed tray 2 is fixed on reduction case 5 by bolt 4, against there being snap ring 3 on the step surface of gear fixed tray 2, snap ring 3 holding is on ring gear 1; The outer wall of gear fixed tray 2 lower end forms gear ring, together with the gear ring of gear fixed tray 2 lower end is meshed with the tooth of ring gear 1, the step surface of gear fixed tray 2 to the distance of gear fixed tray 2 upper-end surface is greater than the distance of step surface to reduction case 5 side ring gear 1 end face of gear fixed tray 2.
A sun gear 7 and multiple planetary pinion 6 is provided with in described ring gear 1, sun gear 7, planetary pinion 6, ring gear 1 mesh together successively, planetary pinion 6 annular is evenly distributed between sun gear 7 and ring gear 1, planetary pinion 6 is fixed on planet carrier 8, planet carrier 8 is fixedly connected on output shaft, output shaft is by bearing hinge connection on reduction case 5, and sun gear 7 is fixedly connected on input shaft, input shaft by bearing hinge connection on reduction case 5.
Described gear fixed tray 2 is provided with multiple bolt 4, and bolt 4 annular is evenly distributed on gear fixed tray 2.
Working principle: current planet reduces device and forms by by sun gear 6, planetary pinion 7, planet carrier 8 and ring gear 1, ring gear 1 is completely fixed in and reduces on device casing 5, and input shaft is connected with sun gear 6, power is delivered to planetary pinion 7 by sun gear 6, planetary pinion 7 rotates on ring gear 1, thus drive planet carrier 8 to rotate, thus pass through planet carrier 8 by transmission of power to output shaft.And because of in actual production process, gear, casing manufacture can produce error, add the error in assembly process.There will be load uneven distribution on three planetary pinions wheels during the running of retarder, serious meeting causes broken teeth, affects operating life.Thus the utility model uses ring gear 1 to be connected with gear fixed tray 2 by the half gear teeth, use snap ring 3 to make axially locating simultaneously, be connected with reduction case 5 by gear fixed tray 2 again, and this design is because ring gear 1 is connected with gear fixed tray 2 and there is certain gap, therefore ring gear 1 is floating, be not completely fixed, when planetary gear speed reducing mechanism transmission, according to the change of load, ring gear 1 can regulate automatically, three planet wheels are all carried, ensures its working life.
