Description
(54)ПЛАНЕТАРНАЯ ПЕРЕДАЧА ВИНТ-ГАЙКА КАЧЕНИЯ(54) PLANETARY TRANSMISSION SCREW NUT
Изобретение относитс к механическим передачам и может быть использовано дл точного преобразовани вращательного движени в поступательI вое, например, в проводах подач стан ков в грезоподъемных механизмах, в измерительных устройствах. Известна планетарна передача . винт-гайка качени , содержаща винт, ходрвую гайку и ролики-сателлиты tlj« Однако в этой передаче дл опор винта используютс стандартные подшипники качени , в которых число точек контакта тел качени с кольцами меньше, чем число точек контакта в сопр жении роликов-сателлитов с гайкой и винтом, что ограничивает нагрузочную способность и жесткость всей передачи, Наиболее близким к изобретению вл етс планетарна передача винт-гайка качени , содержаща винт, ходовую гайку, опорные гайки и роники-сателли ты, св зывающие винт с ходовой IT опорными гайками 23, Однако ролики-сателлиты этой передачи выполнены длинными , общими дл ходовой и опорных гаек, что повышает требовани по накопленной ошибке щага резьбы и усложн ет конструкцию и процесс изготовлени передали. Цель изобретени - упрощение конструкции и процесса изготовлени передачи. Указанна цель достигаетс тем, что в планетарной передаче винт-гайка качени ка дь1й ролик-сателлит выполнен из частей, одна из которых расположена в ходовой гайке, а другие в опорных. На чертеже показана планетарна передача винт-гайка качени , общий вид. Передача содержит винт 1, ходовую гайку 2 с роликами-сателлитами 3 и сепаратором 4, опорные гайки 5 с роликами-сателлитами 6 и сепараторомThe invention relates to mechanical transmissions and can be used to accurately convert rotary motion into translation, for example, in machine feed wires in dream-lifting mechanisms, in measuring devices. Known planetary gear. rolling screw-nut containing screw, jaw nut and satellite rollers tlj "However, in this gear standard screw bearings are used for screw bearings, in which the number of points of contact of the rolling bodies with the rings is less than the number of points of contact with the satellite rollers nut and screw, which limits the load capacity and stiffness of the whole gear. The closest to the invention is a planetary screw-nut gear drive containing a screw, spindle nut, support nuts and roniki satellites connecting the screw with the heading IT ornymi nuts 23, however the rollers of the satellite transmission are made long, common to the chassis and supporting nuts, which increases the demands on the accumulated error schaga thread and complicates the design and manufacturing process passed. The purpose of the invention is to simplify the design and manufacturing process of the transmission. This goal is achieved by the fact that, in the planetary gear, the screw-nut roller and the satellite-roller are made of parts, one of which is located in the running nut and the other in the supporting nut. The drawing shows the planetary gear screw-nut transmission, general view. Transmission contains screw 1, spindle nut 2 with satellite rollers 3 and separator 4, support nuts 5 with satellite rollers 6 and separator
7. Угол подъема резьбы роликов-сателлитов 3 равен по величине и направлению углу подъема резьбы ходовой гайки 2 и не равен углу подъема ходового участка резьбы винта 1. Угол подъема резьбы роликов-сателлитов 6 равен по величине и направлению углу подъема резьбы опорных гаек 5 и равен по величине, но противоположен по направлению углу подъема опорных участков резьбы винта . Ходовой и опорные участки резьбы винта 1 могут иметь как одинаковые, так и различные па1 аметры.7. The elevation angle of the thread of the satellite rollers 3 is equal in magnitude and direction to the angle of elevation of the thread of the running nut 2 and is not equal to the angle of elevation of the screw threaded track 1. Angle of elevation of the thread of satellite rollers 6 is equal in magnitude and direction to the angle of elevation of the thread of the supporting nuts 5 and equal in magnitude, but opposite in the direction of the elevation angle of the support sections of the screw threads. The running and supporting sections of the screw thread 1 can have both the same and different parameters.
Передача работает следукндам образом .The transfer works in the following way.
При вращении винта 1 относительно неподвижной упорной гайки 5 происходит осевое перемещение ходовой гайки 2. Усилие от нагрузки передаетс от ходовой гайки 2 на винт 1, а с винта на опорную гайку 5 и на основание (на чертеже не показано).When the screw 1 is rotated relative to the fixed stop nut 5, the axle 2 is moved axially. The load is transferred from the nut 2 to screw 1, and from the screw to the support nut 5 and to the base (not shown).
За счет выполнени роликов-сателлитов из частей, одна из которых расположена в ходовой гайке, а другие в опорных, могут быть снижены требова-ни по нгшопленной опшбке шага резьбы элементов передачи, что упрощает и снижает трудоемкость процесса изготовлени .Due to the implementation of satellite rollers of the parts, one of which is located in the spindle nut and the other in the bearing, the requirements for transferring the thread pitch of the transmission elements can be reduced, which simplifies and reduces the complexity of the manufacturing process.
