Power oil circulation supply device for thin oil lubrication system

Abstract

The invention discloses a power oil circulation supply device for a thin oil lubrication system, and belongs to the technical field of mechanical transmission. The power oil circulation supply devicefor the thin oil lubrication system comprises a high-speed rotating power source (1), a machine frame, a quincuncial elastic coupling (3) and a SXF series bidirectional lubricating oil pump (4). The high-speed rotating power source (1) provides high-speed rotating power, and the high-speed rotating power is 1000rpm. The machine frame supports the whole power oil supply device. The quincuncial elastic coupling (3) is connected with the high-speed rotating power source (1) and an input shaft of the SXF series bidirectional lubricating oil pump (4). The SXF series bidirectional lubricating oil pump (4) provides fixed flow direction power oil. The machine frame is composed of a planetary reducer shell (21), a planetary reducer lubrication system connecting sleeve (22) and an adjusting machineframe (23). The power oil circulation supply device for the thin oil lubrication system has the advantages that the problems of oil leakage at the sealing position of a shaft head of the lubricating oil pump, abnormal operation of the lubricating system and short service life of the system are solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular provides a power oil circulation supply device for a thin oil lubrication system, and the shaft shoulder seal of an input shaft of a lubricating oil pump is efficiently protected. Background technique [0002] Thin oil lubrication system is mainly composed of power oil (or pressure oil) rotation supply device, hydraulic triple piece and system pipeline. The pressure oil provided by the power oil supply device flows normally in the system pipeline to complete the functions of lubrication, cooling and cleaning of lubricating parts. The operation of the power oil supply device must be safe and reliable, and have a certain life. [0003] At present, in the field of mechanical transmission, SXF series bidirectional lubricating oil pumps are widely used in the lubrication and cooling systems of reducers; the oil pump is connected to the reducer through a coupling, and...
