On multiple stage pumping interface.
Further, described cooler is arranged on the lubricating oil pipeline of oil-out connection of oil pump.
Preferably, described cooler uses panel cooler.
In motor sliding bearing lubrication assistant chiller of the present utility model, the power shaft of described oil pump passes through belt
Drive mechanism, gear drive or frictional wheel drive mechanism are connected with electric machine shaft driving.
This utility model, on the premise of not increasing lubricating oil station, increases on the basis of using ring-oil motor device
Lubricating oil subsidiary loop, pumps the lubricating oil bottom sliding bearing oilcan to top, gets rid of oil lubrication at Bearing inner oil ring
Meanwhile, by external lubrication loop lubrication assistant, loop arranges filter, the copper scale within lubricating oil, iron filings can be entered
Row filters, it is to avoid sliding bearing is caused abrasion；Cooler is set on lubricating oil subsidiary loop simultaneously, is connect by forced circulation
Enter cooler lubricating oil is cooled down, it is to avoid Bearing Temperature breaks down, it is ensured that motor safety runs steadily in the long term.
From the above mentioned, this utility model has the advantages that
(1) utilizing the rotation of equipment motor itself, (can use belt, gear, friction pulley etc. passes indirectly to drive oil pump operating
Flowing mode or axle head connect directly driving), improve system reliability, reduce electric energy loss, it is not necessary to again install circulation petrol station system additional
System, is not limited by existing place.
(2) by filter, the impurity in oil is filtered, it is to avoid copper scale, iron filings that disc abrasion produces enter sliding
Dynamic bearing causes abrasion.
(3) access cooler by forced circulation, cooling effect can be greatly improved.
(4) ensure that the safety of large-size machine is steady in a long-term to run, there is preferable economic benefit.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
