Description
Изобретение относитс к области общего Мсоциностроени , в частности к двухступенчатым редукторам с выходными валами, вращающимис в противоположные стороны с равной угловой скоростью. Известен планетарный редуктор, имеющий передаточное отношение, равное двум, и содержа1дий ведущий вал, два коаксиально установленных ведомых вала, вращающихс в противополож ные стороны с равной угловой скоростью , две планетарные ступени, состо щие кажда из солнечного колеса, эпи цикла и водила с сателлитами, ведущий вал соединен с солнечным колесом первой ступени, водило первой ступени заторможено, а водило второй ступени соединено с внутренним ведоким валом 1 . Недостатком такого редуктора вл етс необходимость использовани в планетарных ступен х зубчатых колес с разными параметрами (числом зу бьев, модулем и исходным контуром ), что удорожает стоимость изготовлени эксплуатации и ремонта редуктора. Цель изобретени - снижение стоимости редуктора. Дл этого колеса обеих ступеней выполнены идентичными, ведущий вал соединен с эпициклом второй ступени, а эпицикл первой ступени - с наружным ведомым валом. На чертеже дана схема редуктора. Редуктор содержит две планетарные ступени Q и t) и корпус 1. Перва планетарна ступень О имеет солнечное колесо 2, соединенное с ведущим валом 3, эпицикл 4 и сателлиты 5, водило 6 которых соединено с корпусом 1. Втора планетарна ступень Тэ имеет эпицикл 7, св занный с ведущим валом 3, солнечное колесо 8 и сателлиты 9, водило 10 которых соединено с внутренним ведомь1М валом 11. В корпусе, соосно ведомому валу 11, установлен на опорах вращени наружный ведомый вал 12, соединенный с солнечным колесом 8 ступени Ъ и эпициклом 4- ступени а. При этом ведущий вал 3 соединен с эпициклом 7 ступени , а солнечное колесо 8 ступени J соединено с наружным ведомым валом 12. Число зубьев, модуль и исходный контур зубчатых колес 4 и 7, 5 и 9, 2 и 8 соответственно одинаковы.The invention relates to the field of general Mscine construction, in particular to two-stage gearboxes with output shafts rotating in opposite directions with equal angular velocity. A planetary gearbox is known, having a gear ratio equal to two and containing a driving shaft, two coaxially mounted driven shafts rotating in opposite directions with equal angular speed, two planetary stages consisting each of a sun wheel, epi cycle and drove with satellites, the drive shaft is connected to the sun wheel of the first stage, the carrier of the first stage is inhibited, and the carrier of the second stage is connected to the internal drive shaft 1. The disadvantage of such a gearbox is the necessity of using gears with different parameters (number of teeth, module and initial contour) in the planetary gear stages, which increases the cost of manufacturing the operation and repair of the gearbox. The purpose of the invention is to reduce the cost of the gearbox. For this, the wheels of both stages are identical, the drive shaft is connected to the second stage epicycle, and the first stage epicycle is connected to the external driven shaft. The drawing is a diagram of the gearbox. The gearbox contains two planetary stages Q and t) and body 1. The first planetary stage O has a sun wheel 2 connected to a drive shaft 3, an epicycle 4 and satellites 5, the carrier 6 of which is connected to the body 1. The second planetary stage Te has an epicycle 7, connected to the drive shaft 3, the sun wheel 8 and the satellites 9, the carrier 10 of which is connected to the internal slave 1M shaft 11. In the housing, coaxially the driven shaft 11, the external driven shaft 12 connected to the rotation wheel 8 and the epicyc 4 steps a. In this case, the drive shaft 3 is connected to the epicyclic stage 7, and the sun wheel 8 stage J is connected to the external driven shaft 12. The number of teeth, the module and the initial contour of gears 4 and 7, 5 and 9, 2 and 8, respectively, are the same.
Редуктор работает следукадим образом .The gearbox works in the following way.
При вращении ведущего вала 3 вравдаютс колеса 2 и 7, наход щиес в зацеплении с сателлитами 5 и 9.When the drive shaft 3 rotates, the wheels 2 and 7 are engaged with the satellites 5 and 9.
Сателлиты 5, наход сь в зацеплении с эпициклом 7 и солнечньам колесом 8, .вргицаютс последними и, планетарно перемеща сь, вращают водилоThe satellites 5, which are in engagement with the epicycle 7 and the sun wheel 8, are the last to be rotated and, moving planetary, rotate the carrier
10и св занный с ним внутренний ведомый вал 11,10 and its associated internal output shaft 11,
Угловые скорости вращени валовAngular speeds of shaft rotation
11и 12 одинаковы, направлени их вращени противоположны, а отноше ние оборотов ведущего вала 3 к оборотам валом 11 и 12 равно двум.11 and 12 are the same, the directions of their rotation are opposite, and the ratio of the revolutions of the drive shaft 3 to the revolutions of the shaft 11 and 12 is equal to two.
Изобретение позвол ет за счёт идентичности выполнени зубчатых колес ступеней; значительно снизить стоимость редуктора.The invention allows, due to the identity of the gears of the steps; significantly reduce the cost of the gearbox.
