Description
II
Изобретение относитс к станкостроению, непосредственно к механизмам станков, которые содержат элементы с возвратно-поступательным пр молинейным перемещением.The invention relates to a machine tool industry, directly to the mechanisms of machine tools that contain elements with reciprocating rectilinear movement.
Известна черв чно-реёчна передача с гидростатической смазкой, содержаща черв чную рейку с карманами дл маспа, черв к, установленный на станине, маслоподвод щие каналы, выполненные в рейке или черв ке 1}.The famous worm-gear rack with hydrostatic lubrication contains a worm rail with masks pockets, a worm, mounted on a frame, oil supply channels made in a rail or a worm 1}.
Недостатком указанной передачи вл етс сложность изготовлени маслоподвод щнх каналов в черв ке или рейке.The disadvantage of this transfer is the difficulty of manufacturing the oil supply channels in the screw or rail.
Наиболее близкой ,по технической сущности вл етс черв чно-реёчна передача с гидростатической смазкой, содержаща черв чную рейку с карманами дл масла, вал и размещенный на нем цилиндрический черв к, имеющий маслоподвод щие каиалы, соединенные с рабочими поверхност ми витков черв ка выполненными в нем отверсти ми, а выходные отверсти маслоподвод щих каналов расположены на торцовых поверхност х черв ка равномерно по окружности, и разгруженные сегментные маслораспределители 2.The closest to the technical essence is a worm-gear drive with hydrostatic lubricant, which contains a worm rail with pockets for oil, a shaft and a cylindrical worm on it, having oil-feed cages connected to the working surfaces of turns of a worm made in It has openings, and the outlet openings of the oil supply channels are located on the end surfaces of the screw evenly around the circumference, and the unloaded segment oil distributors 2.
Однако така передача имеет .сложную конструкцию .However, such a transmission has a complex structure.
С целью упрощени конструкции в предлагаемой черв чно-реечной передаче с гидростатической смазкой маслоподвод щие каналы представл ют собой продольные профильные пазы, выполненньте на посадочных поверхност х вала черв ка и длина которых определена положением крайних витков черв ка.In order to simplify the design of the proposed worm gear with hydrostatic lubrication, the oil supply channels are longitudinal grooves, made on the shaft seating surfaces of the screw and whose length is determined by the position of the extreme turns of the screw.
На чертеже изображена черв чно-реечнаЯ| передача с гидростатической смазкой.The drawing shows a red-plated worm | gear with hydrostatic lubrication.
Она содержит черв чную рейку 1 с карманами 2 дл масла, вал 3 и размещешлт ил кем цилиндрический черв к. 4, маслоподвод щие каналы 5, соединенные с.рабочими поверхност ми витков черв ка наклонными отверсти ми 6, выполненными в его корпусе, разгруженные сегментные маслораспределители 7 и 8, служащие дл подвода масла к торцам черв ка, и корпус 9.It contains a worm rail 1 with pockets 2 for oil, a shaft 3 and accommodates a cylindrical worm c. 4, oil supply ducts 5 connected by working surfaces of worm turns with inclined holes 6 made in its body, unloaded segment oil distributors 7 and 8, serving for supplying oil to the ends of the screw, and housing 9.
Работает передача следующим образом.The program works as follows.
Вал 3 с напрессованным корпусом черв а 4 вращаетс в опорах корпуса 9 черв чнореечной передачи с гидростатической, смазкойThe shaft 3 with the pressed housing of the screw and 4 rotates in the supports of the housing 9 the screw of the transducer with hydrostatic lubrication
