(54) ПЛАНЕТАРНАЯ ЗУБЧАТАЯ ПЕРЕДАЧА(54) PLANETARY GEAR TRANSMISSION

II

Изобретение относитс к машиностроению и может быть испопьзовано в редукторостроении .The invention relates to mechanical engineering and can be used in gear design.

Известен редуктор с раздвоением си нового потока, содержащий ведущую и ведомую ступени с установленными на них зубчатыми колесами и пружинную муфту, установленную между этими ступен Еми. выравнивание нагрузок между ветв ми обеспечиваетс муфтой, благодар которой зубчатые колеса ведомой ступени незначительно проворач таютс и смещаютс вдоль оси .A reducer with a split of a new flow is known, containing a leading and a driven stage with gears mounted on them and a spring clutch installed between these steps Emi. the alignment of the loads between the branches is provided by a clutch, due to which the gears of the driven stage slightly rotate and move along the axis.

Указанный редуктор выполнен р дным а значительна жесткость пружинного звена муфты не позвол ет полностью вырсюн ть нагрузку по силсюым потокам. . Наиболее близким к предлагаемому изобретению по те5шической сущности и достигаемому результату вл етс планетарна зубчата передача, содержаща центральные колеса наружного и внутреннего зацеплени и водило с установленными на его оси сателлитами, каждыйThis gearbox is made of a regular and significant rigidity of the clutch spring link does not allow to fully relieve the load on the strong flows. . The closest to the invention according to the technical essence and the achieved result is a planetary gear transmission containing central wheels of external and internal gearing and drove with satellites installed on its axis

из которык имеет набор чередуюш.ихс между собой ведущих и ведомых подпружиненных в осевом направлении фрикцион нык дисков, снабженных зубчатыми венца- ми, заиепл нэщихс соответственно с цент ральными колесами наружного и внутреннего зацеплени 2|.of which has a set of alternating drives between each of the leading and driven axially spring-loaded friction disks of disks equipped with toothed rims, respectively, with central wheels of external and internal gearing 2 |.

Выравнивание нагрузок по сателлитам осуществл етс благодар св зи дисков сателлитов между собой поверхност ми трени . Неодинаковость зат жки дисков вследствие низких фрикционных свойств последних не обеспечивает достаточной равномерности распределени по сйтеп- питам.Alignment of loads on satellites is carried out due to the connection of satellite disks with each other by friction surfaces. The difference in the tightening of the discs due to the low frictional properties of the discs does not ensure a sufficiently uniform distribution over the pitteers.

Цель изобретени - увеличение рав номерности распределени нагрузки по сателлитам.The purpose of the invention is to increase the uniform distribution of the load on the satellites.

Claims

This chain is achieved by the fact that the transmission is equipped with a friction clutch, the disks of which are located between the disks of the satellites and secured against rotation on the axis of the satellite. The drawing shows a planetary gear, longitudinal section. The transmission has body 1, led 2 and slave 3 wapes in it. On the leading wapa 2, an outer gear 4 is installed centrally. The central wheel 5 of the internal engagement is made in the form of a disk pack and is fixed to the B case 1, and the central wheel 6 of the internal fastening is connected with the driven shaft 3, On axis 7 the carrier 8 is mounted satellites made in the form of a set of alternating leading 9 and the slave 10 under the spring-loaded friction discs equipped with toothed rims, and the crown 1.1, rigidly connected with the axis 7. The alternating tsiski 9 and 1O, mounted on the sleeves 12, are filled with bearings and separated between them fixed from the rotation on the axis 7 of the disk 13 of the friction clutch. The whole set of disks 9, 10 and 13 is compressed by means of clamping washers 14, springs 15 located in the hole of the axis 7. The driving disks 9 interact with the central wheel 4, the driven disks 1O interact with the central wheel 5, and 11 seconds. central koiesy b. With a chain of magnification. Friction discs 9 and 10 can be made with friction linings built into the body of the discs. The transmission operation is compressed as follows. From the drive shaft 2 through the central assembly 4, the rotation is transmitted to the drive disks 9 of the satellite and through the friction surfaces to the friction disks 13 and then through the disks 1O of the satellite, which are rolled through the disks of the central wheel 5 ,. the tooth of the satellite crown 11 of the satellite and the carrier 8 are rotated. Next, the rotation wheel is transmitted through the gear winches 11 to the central wheel 6 with the internal drive wheel and to the driven shaft. between the satellites, when at the application of the torque torus, the disks and individual satellites are sequentially turned until they have entered into operation, and when the moment is exceeded all discs slip, due to which the transmission as a whole is prevented from overloading. Due to the presence of a friction connection between the gear teeth of the satellite, there is a more uniform distribution of the load between the satellites and its limitation in size, which increases the reliability and durability of the transmission, thus eliminating the limitations in the selection of the number of teeth associated with the use of several satellites. Formula of the Invention Planetary gear transmission comprising central wheels of external and internal gearing and carrier with satellites mounted on its axis, each of which has a set of alternating D: axially spring-loaded friction disks fitted with toothed rims engaging respectively with central wheels of external and internal gearing, characterized in that, with a chain of increasing the uniformity of load distribution over the satites, it is provided with fricks onnoy clutch discs which are disposed between the satellites and the fixed disks against rotation on the axis of the satellite.
