偏航变桨齿轮箱及其快换接头

Yawing variable pitch gearbox and quick-change connector thereof

Abstract

The invention discloses a quick-change connector, which comprises a primary connector and a secondary connector, wherein the primary connector is a normally stopped connector which is connected under the action of axial movement of a valve plug (12); the secondary connector can be inserted into the primary connector and push the valve plug (12) to move axially; and one end of the secondary connector is provided with a first connecting part which is connected with a pipeline. The quick-change connector is installed at one time and is not needed to be detached. The secondary connector is connected with an oil filling/draining pipe; and during use, the secondary connector is inserted into the primary connector on a yawing variable pitch gearbox, and the oil is filled or drained easily and rapidly. The primary connector has a one-way non-return form, and cannot be connected under the action of inner oil pressure of the gearbox but can be connected under an external pressure; therefore, the gearbox cannot leak oil, and the oil is filled easily. The invention also discloses a yawing variable pitch gearbox with the quick-change connector.
本发明公开了一种快换接头,包括:母接头,其为在其阀芯(12)轴向移动的作用下导通的常止接头;可插设在所述母接头上,并推动所述阀芯(12)轴向移动的子接头(15),且其一端具有与管路连接的第一连接部。本发明一次安装,无需拆卸。子接头与加放油管相连,使用时,将其插入安装在偏航变桨齿轮箱上的母接头上,即可实现加油或放油,方便快捷。母接头为单向逆止形式,不会在齿轮箱内油压作用下接通,而在外部压力下可以接通,这样即能保证齿轮箱不漏油,又能保证加油方便。本发明还公开了一种具有上述快换接头的偏航变桨齿轮箱。
