Description
(54) ПЛАНЕТАРНАЯ ВИНТОВАЯ ПЕРЕДАЧА КАЧЕНИЯ(54) PLANETARY SCREWING TRANSFER OF QUALITY
: ,. 1 :,. one
Изобретение относитс к механическим передачам и может быть использовано в приводах подач станков, грузоподъемных механизмах , в измерительных устройствах.The invention relates to mechanical gears and can be used in machine feed drives, lifting mechanisms, in measuring devices.
Известна планетарна винтова -передача качени , содержаща корпус, ведущий элемент, выполнен в виде центрального ролика с винтовой нарезкой и зубчатыми венцами , нарезанными на его концах, взаимодействующие с ним ролики-сателлиты, и ходовую гайку 1.The planetary propeller is known; the rolling transmission, comprising a housing, a driving element, is designed as a central roller with a screw thread and a gear rims, cut at its ends, satellite rollers interacting with it, and a running nut 1.
Недостатком этой передачи вл етс то, что ролики-сателлиты могут проскальзывать относительно ходовой гайки, при этом точна кинематическа св зь входного и выходного звеньев нарущаетс .The disadvantage of this transmission is that the satellite rollers can slip relative to the spindle nut, and the exact kinematic coupling of the input and output links is disrupted.
Наиболее близким к изобретению по технической сущности вл етс планетарна винтова передача качени , содержаща закрепленное в корпусе коронное колесо, ведущий , элемент, выполненный в виде центрального ролика с винтовой нарезкой и зубчатыми венцами, нарезанными на его концах , взаимодействующие с ним ролики-сателлиты , имеющие винтовую нарезку, угол подъема которой равен по величине и противоположен по направлению углу подъема винтовой нарезки центрального ролика, и зубчатые венцы, нарезанные на концах, одни из которых взаимодействуют с коронным колесом и с зубчатыми венцами центрального ролика, и ведомый элемент 2.The closest to the invention to the technical essence is the planetary rolling gear drive, which contains a crown wheel fixed in the housing, a driving member, an element made in the form of a central roller with screw thread and gear rims cut at its ends, satellite rollers interacting with it, having a screw thread, the lifting angle of which is equal in magnitude and opposite in the direction of the lifting angle of the screw cutting of the central roller, and toothed crowns, cut at the ends, some of which are interactions with a crown wheel and with the toothed rims of the central roller, and the driven member 2.
Недостатком известной передачи вл етс большой радиальный габаритный размер, обусловленный тем, что вс осева нагрузка воспринимаетс центральным роликом, несуща способность которого при этом ограничена.A disadvantage of the known transmission is the large radial dimension, due to the fact that the full axial load is perceived by the central roller, the carrying capacity of which is limited.
Цель изобретени - уменьшение радиальных габаритных размеров передачи и увеличение ее несущей способности.The purpose of the invention is to reduce the radial dimensions of the transmission and increase its carrying capacity.
