Oil supplementing system for gearbox

Abstract

The invention discloses an oil supplementing system for a gearbox, and belongs to the technical field of gearbox lubricating systems. The oil supplementing system for the gearbox comprises oil tanks,control valves, a one-way valve and an oil pump. The first oil tank is arranged at a high position relative to the gearbox, and the second oil tank is arranged at a low position relative to the gearbox. The first control valve is arranged on a first oil guide way where the first oil tank communicates with a first oil inlet and used for controlling the first oil guide way to be blocked or unblocked. The second control valve is arranged on a second oil guide way where an oil outlet communicates with the second oil tank and used for controlling the second oil guide way to be blocked or unblocked.The one-way valve is arranged on a third oil guide way where the second oil tank communicates with a second oil inlet and used for controlling lubricating oil to flow out of the second oil tank to reach the gearbox through the third oil guide way, and the oil pump is arranged on the third oil guide way. The oil supplementing system for the gearbox can achieve the purpose that the gear box can still be lubricated under the power-off working condition and the no-load working condition, and therefore a gear bearing is prevented from being in a dry grinding state.

Description

technical field [0001] The invention relates to the technical field of gearbox lubricating systems, in particular to an oil replenishment system of a gearbox. Background technique [0002] With the development of gearboxes with large megawatt power, the traditional oil tank as a lubrication system for gearboxes can no longer meet the requirements of large flow. The appearance design of the box optimizes the pipeline layout. However, due to the design of the independent oil tank, there is no oil in the gearbox, which is a dry oil pool state. It is difficult to ensure that the gearbox can still be lubricated under power-off and no-load conditions, and the gear bearings cannot be prevented from being in a dry grinding state. Contents of the invention [0003] The purpose of the present invention is to propose an oil replenishment system for a gearbox, which can realize lubrication of the gearbox under power-off and no-load conditions, thus avoiding the dry grinding of the ge...
