Description

Изобретение относитс  к области ме.ханосборочиых работ, в частности к области сборки прессовых конусных соединений гидропрессовым методом.The invention relates to the field of mechanical assembly work, in particular to the field of assembling press cone joints by the hydraulic press method.

Известно устройство дл  сборки запрессовкой гидропрессовым методом деталей типа вал-втулка, содержаш,ее соединенный с гидросистемой , например, масл ной, высокого давлени  силовой пилиндр с поршнем, а Г-образные захваты, установленные на корпусе цилиндра дл  креплени  охватывающей детали.A device is known for assembling, by means of a hydraulic press method, parts such as a shaft bushing, which contain it connected to a hydraulic system, for example, an oil, high pressure power piston with a piston, and L-shaped grippers mounted on the cylinder body for fastening the female part.

Однако известное устройство не обеспечивает сборку прессового конусного соединени , где вал имеет резьбовой хвостовик.However, the known device does not assemble the press cone, where the shaft has a threaded shank.

Цель изобретени  - обеспечение сборки запрессовкой конусного соединени  и создание масл ной пленки в зоне сопр жени .The purpose of the invention is to provide an assembly by pressing in a tapered joint and to create an oil film in the interface.

Это достигаетс  за счет того, что на рабочем торце поршн  выиолнено резьбовое гнездо дл  соединени  с конусным валом, а диаметр поршн  определ етс  по формуле:This is achieved due to the fact that at the working end of the piston there is a threaded socket for connection with a tapered shaft, and the diameter of the piston is determined by the formula:

л - 1/ (/ + tg а) , ,l - 1 / (/ + tg a),,

LJ - у -1-«,,LJ - at -1- “,,

-1,2-1,6рк, давление масла, контактное давление, средний диаметр соединени , длина соединени .-1.2-1.6rk, oil pressure, contact pressure, average connection diameter, connection length.

/ - коэффициент трени , di - диаметр малого основани  конуса вала ,f is the coefficient of friction, di is the diameter of the small base of the shaft cone,

а° - угол конусности. На чертеже показано устройство.and ° is the angle of taper. The drawing shows the device.

Оно содержит кориус 1 силового цилиндра, соединенного с гидросистемой, например масл ной , под высоким давлеиием через штуцер 2. В корпусе силового цилиндра установлен стуиенчатый иоршеиь 3, с выиолненным на нем осевым резьбовым гнездом 4 дл  соединени  с резьбовым хвостовиком конусного сала 5 соединени .It contains a corus 1 of a power cylinder connected to a hydraulic system, for example, oil, under high pressure through fitting 2. In the case of a power cylinder there is a stacked gear 3, with an axial threaded socket 4 formed on it for connection with a threaded shank of conical fat 5.

На корпусе установлены Г-образные захваты 6 дл  установки устройства на собираемой конусной втулке 7.On the case there are mounted l-shaped grippers 6 for mounting the device on the assembled conical sleeve 7.

Работа устройства заключаетс  в том, что конусную втулку 7 соединени  надевают на конусный вал 5.The operation of the device lies in the fact that the cone sleeve 7 of the joint is put on the cone shaft 5.

Затем к резьбовому концу вала подсоедин етс  резьбовым гнездом ступенчатый поршень 3. Носле чего Г-образными захватами 6 втулку 7 закрепл ют к корпусу 1 силового цилиндра и подвод т масло под давлением от гндромагистралн через штуцер 2 в полость силового цилиндра. Под действием давлени  масла на кольцевую нлошадку 8 поршн  3 поршень вместе с закрепленным на нем конусным валом перемепдаетс  в корпусе цилиндра на велнчину заданного осевого нат га. ПриThen, a stepped piston 3 is connected to the threaded end of the shaft with a threaded socket. Then, the sleeve 7 is fixed to the body 1 of the power cylinder by means of L-shaped grippers 6 and the pressurized oil from the main line is fed through the union 2 to the cavity of the power cylinder. Under the action of oil pressure on the annular heading 8 of the piston 3, the piston, together with the cone shaft fixed on it, interleaves in the cylinder body on the barrel of a given axial tension.
