Abstract

Изобретение позвол ет упростить техобслуживание объемной гидромашины и снизить эксплуатационные затраты. Ротор выполнен составным из двух частей 20, 22. Наружна часть 22 образует с корпусом 1 рабочие камеры. Внутренн опорна часть 20 установлена на валу 2. Часть 20 имеет форму диска и соединена с частью 22 жестким разъемным соединением, что позвол ет производить разборку гидромашины многократно и без использовани специальных съемников. 3 ил.The invention allows to simplify the maintenance of a volumetric hydraulic machine and reduce operating costs. The rotor is made up of two parts 20, 22. The outer part 22 forms working chambers with body 1. The inner support part 20 is mounted on the shaft 2. The part 20 is disk-shaped and is connected to part 22 by a rigid plug connection, which allows disassembling the hydraulic machine repeatedly and without using special pullers. 3 il.

Изобретение относитс к гидромашиностроению , в частности к роторным гидромашинам , и вл етс дополнительным к аат.св. № 1551812.The invention relates to hydraulic machine building, in particular to rotary hydraulic machines, and is in addition to aatc. No. 1551812.

Целю изобретени вл етс упрощение техобслуживани гидромашины и снижение эксплуатационных расходов.The purpose of the invention is to simplify maintenance of the hydraulic machine and reduce operating costs.

Нэ фигЛ изображена объемна гидромашина , общий вид; на фиг.2 - то же, про- дольное сеченме; на фиг.З - вид на гидромашину со стороны приводного вала.Ne figl depicted volumetric hydraulic machines, a general view; figure 2 - the same, the longitudinal section; on fig.Z - view of the hydraulic machine from the drive shaft.

Объемна гидромашина содержит корпус 1 и установленный на валу 2 разборный ротор 3. В корпусе 1 и роторе 3 выполнены участки торообразных поверхностей, сопр женные с образованием торообразного рабочего цилиндра 4, в котором размещен и прикреплен к корпусу 1 замыкатель 5, а также два профилированных кулачка 6 и 7, расположенных по обе стороны от замыкател 5. В роторе 3 установлены поджатые к корпусу 1 пружинами 8 поршни 9, снабженные уплотнени ми 10 и раздел ющие цилиндр 4 на рабочие камеры 11,12 и 13. В корпусе 1, а также в кулачках 6 и 7 выполнены каналы 14 и 15 подвода и отвода рабочей среды, смещенные относительно оси рабочего цилиндра 4. Рабочий цилиндр 4 снабжен уплотнени ми 16 и 17, а замыкатель 5 - уплотнением 18. Вал 2 установлен в подшипниках 19. Ротор 3 сострит из двух частей: внутренней опорной части 20, установленной на валу 2 при помощи шпонки 21, и наружной части 22, содержащейThe volumetric hydraulic machine includes a housing 1 and a collapsible rotor 3 mounted on the shaft 2. The housing 1 and the rotor 3 have sections of toroid-shaped surfaces mated to form a toroid-shaped working cylinder 4, in which a switch 5 is placed and attached to the case 1, as well as two profiled cam 6 and 7, located on either side of the contactor 5. In the rotor 3, pistons 9, which are pressed against the housing 1 by springs 8, are fitted with seals 10 and divide the cylinder 4 into working chambers 11,12 and 13. In housing 1 as well as in cams 6 and 7 are made channel s 14 and 15 of the supply and removal of the working medium, offset from the axis of the working cylinder 4. The working cylinder 4 is provided with seals 16 and 17, and the contactor 5 is sealed 18. The shaft 2 is mounted in bearings 19. The rotor 3 consists of two parts: an internal bearing part 20 mounted on the shaft 2 with a key 21, and the outer part 22 containing

Invention Formula

Bulk gidromashina avt. St. No. 1551812, characterized in that, in order to simplify maintenance and reduce operating costs, the rotor has a working cylinder 4, and the sight of the suit is connected by a detachable connection using bolts 23 and dowel pins 24. To prevent pistons turning

9, they are provided with longitudinal grooves 25, in which pins 26 installed in the rotor 3 are located. Channels 27 are provided in the pistons 9, which communicate the piston cavities 28 with one of the chambers of the cylinder 4.

Bulk gidromash can work both as a pump and as a hydraulic motor.

When operating as a pump, shaft 2 is rotated and, with it, rotor 3 with pistons 9 is blended. The working medium is sucked through working medium supply channel 14 and then is forced out through channel 15 to the consumer. When the piston 9 approaches the contactor 5, the spring 8 is compressed and the piston 9 is raised, tracing the profile of the cams 6 and 7.

The collapsible rotor 3 permits disassembling the hydraulic machine in order to flush its working cylinder 4, without removing the inner support part 20 mounted on the shaft 2 by pressing fit. Bolt-on detachable noseoflsef to disassemble the hydraulic machine repeatedly and without using special pullers.
