Description

Изобретение относитс к машиностроению и может быть использовано в качестве шаровой торцовой передачи в приводах различных механизмов и машин .The invention relates to mechanical engineering and can be used as a spherical face gear in drives of various mechanisms and machines.

Цель изобретени - повышение надежности и увеличение передаваемой мощности путем исключени холостого пробега шаров в каналах возврата.The purpose of the invention is to increase the reliability and increase the transmitted power by eliminating idle run of the balls in the return channels.

На чертеже представлена шарова торцова передача, поперечное сечение .The drawing shows the ball end gear, the cross section.

Шарова торцова передача содер- жкт корпус 1 на стенках которого закреплены заторможенные основной 2 и дополнительный 3 диски.The spherical end gear contains the body 1 on the walls of which the braked main 2 and additional 3 disks are fixed.

Ведущий диск 4 расположен между заторможенным диском 2 и ведомым диском 5. Дополнительный диск 6 установлен между заторможенным диском 2 и ведущим диском 4 и жестко св зан с ведомым диском 5.The driving disk 4 is located between the braked disk 2 and the slave disk 5. An additional disk 6 is installed between the braked disk 2 and the driving disk 4 and is rigidly connected to the slave disk 5.

На обоих дисках 5 и 6 выполнены радиально направленные сквозные пазы , в которых размечены пары 7. Пазы по спирали Архимеда -выполнены на .обеих сторонах ведущего диска 4 и на основном 5 и дополнительном б заторможенных дисках дл взаимодействи с шарами 7. Спиральные пазы дисков 5 и 6 встречны по направлению спиральным пазам диска 4. На диске 4 выполнены осевые отверсти 8 и 9 дд замыкани траектории перемещени щаров 7 между дисками. Отверсти 8 и 9 наклонены к оси передачи.Both disks 5 and 6 have radially directed through grooves in which pairs 7 are marked. The grooves in the Archimedes spiral are made on both sides of the drive disk 4 and on the main 5 and additional braked disks to interact with the balls 7. The spiral grooves of the disks 5 and 6 are opposite in direction to the spiral grooves of the disk 4. On the disk 4 there are axial holes 8 and 9 dd to close the path of movement of the balls 7 between the disks. Holes 8 and 9 are inclined to the transmission axis.

Шарова торцова передача работает следующим образом,.Sharov end gear works as follows.

При вращении ведущего диска 4 шары 7 кат тс по пазам и вовлекают во вращение диски 5 и 6. При этом заторможенные диски 2 и 3 св заны с корпусом 1, что повышает жесткость конструкции. При достижении шаром 7 отверсти 8 или 9 он под действием . усилий, действующих в передаче, пере15When the drive disk 4 rotates, the balls 7 are cut along the grooves and involve the disks 5 and 6 in rotation. In this case, the braked disks 2 and 3 are connected with the housing 1, which increases the rigidity of the structure. When the ball reaches 7 holes 8 or 9, it is under the action. effort acting in transmission, re 15
