Изобретение относитс к машиностроению и может быть использовано в приводах различных механизмов и машин.The invention relates to mechanical engineering and can be used in drives of various mechanisms and machines.

Известна фрикционна планетарна передача, содержаща корпус, водило с сателлитами, взаимодействующие .с ними центральные колеса одно из которых заторможено, и нажимной мёха низм 1 .10A known friction-mounted planetary gear, comprising a housing, drove with satellites, the central wheels interacting with them, one of which is braked, and the pressure wheel 1 .10

К недостаткам этой передачи относитс то, что заторможенное -центральное колесо выполнено разрезным, что ограничивает скоростные и нагрузочные возможности передачи. tsThe disadvantages of this transmission include the fact that the braked central wheel is split, which limits the speed and load transmission capabilities. ts

Ближайшей по технической суи1ности к изобретению вл етс фрикционна планетарна передача, содержаща корпус, размещенный в нем планетар144Й р д, включаюи1ий водило с сател- 20 лигами, взаимодействующие с ними центральные колеса, одно из которых заторможено, и нажимной механизм с гайкой 2.The closest in technical importance to the invention is a friction planetary gear, comprising a housing, a planetar144 located in it, including a carrier with satellite 20 leagues, associated central wheels, one of which is braked, and a pressure mechanism with a nut 2.

К недостаткам этой передачи относитс необходимость многократных разборок и сборок передами дл получени требуемой величины нажимного усили и, соответственно, передаваемого вращакчего момента. При этом сложности регулировки нажимного усили увеличивснотс при установке в одном корпусе нескольких планетарных р дов.The disadvantages of this transmission include the need for multiple disassemblies and assemblies in front to obtain the required amount of pressure force and, accordingly, the transmitted torque. At the same time, the complexity of adjusting the pressure force increases when several planetary rows are installed in one housing.

Целью изобретени вл етс упрощение регулировки величины нажимного усили при размещении в корпусе не;скольких последовательно соединенных планетарных р дов.The aim of the invention is to simplify the adjustment of the magnitude of the pressing force when several non-serial planetary rows are placed in the housing.

Указанна цель достигаетс тем, что передача снабжена стопорными элементами, посредством которых водило и гайка каждого из р дов св заны с корпусом, а последний имеет окно дл доступа к гайкам.This goal is achieved by the fact that the gear is provided with locking elements by means of which the carrier and nut of each of the rows are connected to the housing, and the latter has a window for accessing the nuts.

Claims

The drawing schematically shows a part of the friction planetary gear, including one of the planetary rows. The friction planetary gear includes a housing 1, a planetary row accommodated in it, including a carrier 2 with satellites 3 interacting central wheels k; AND 5, of which the wheel 5 is braked, the pressure mechanism 6 with a nut 7, and the locking elements 8 and 9 by means of which, respectively, drove 2 and the nut 7 are connected to a housing having a window 10 for accessing the nut 7. The friction planetary gear operates as follows. , When the central wheel k rotates, the satellites 3 roll around the braked central wheel 5 and rotate the carrier 2. The pressure force in the frictional contacts of the satellite 3 with the central wheels k and 5 is created by rotating and axially moving the nut 7. During assembly and during operation when it is necessary to adjust the value of the transmitted torque, with the help of the locking element 8 of the first planetary row the carrier 2 is connected to the housing 1J. Then, using known methods, the central wheel is rotated yuschy moment equal calculated for a given row. Through the window 10 in the housing t, the nut 7 of the pressure mechanism 6 is tightened until the central wheels i and 5 and the satellites 3 stop slipping relative to each other. After that, using the locking element 9, the nut 7 is connected to the housing 1, i.e. . the locking element 9 contour Yaiku 7 and closes the window 10 After the adjustment of the pressing force is completed In the first row of sections, the locking element 8 is disconnected from the carrier 2, thus disconnecting the carrier 2 with the housing 1. The adjustment of the pressing forces c. the links x of the subsequent planetary rows are made similarly. Such an embodiment of the friction planetary gear allows both during assembly and in operation to establish and maintain a predetermined amount of transmitted gear. moment without disassembling the transmission itself. The formula of the invention is a friction planetary gear, comprising a housing, a planetary row accommodated therein, including a carrier with satellites, interacting central wheels with them, one of which is braked, and a pressure mechanism with a nut, which is different in that pressure force when placed in the body of several series-connected planetary rows, it is equipped with locking elements, by which; the carrier and nut of each of the rows are associated with the housing, and the latter has a window for accessing the nuts.
