Technical field
The present invention relates to a kind of back pressure type rotor intermediate bearing lubricating fitting, belong to variable speed fluid coupling lubrication system technical field.
Background technique
Variable speed fluid coupling input and output power transimission completes mainly through pump impeller in rotor and turbine assembly.Pump wheel shaft and turbine shaft are connected by an intermediate bearing (spheric roller bearing) makes diaxon be in same central position, when pump impeller, turbine, intermediate bearing is subject to the frictional force that pump impeller and turbine rotation round power and gravity produce, and therefore must have the good lubrication guarantee fluid coupling normal work and use overhaul life.
The existing lubricating fitting being applied to variable speed fluid coupling lubrication system intermediate bearing as shown in Figure 1, primarily of compositions such as former oil inlet pipe 4, Pump wheel shaft 2, intermediate bearing 7, intermediate bearing sleeves 8.Pump wheel shaft 2 end is fixed on variable speed fluid coupling casing 1 by bearing support 3, intermediate bearing 7 is contained on Pump wheel shaft 2 by middle bearing bracket 8, pump impeller 6 is closely connected by middle bearing bracket 8 and intermediate bearing outer ring 9, pump impeller end cap 5 is fixedly connected with pump impeller 6, and the former oil inlet pipe 4 be connected with oil storage casing is housed outside pump impeller end cap 5.
During variable speed fluid coupling work, lubricant oil is by equally distributed oil through on former oil inlet pipe 4 directive Pump wheel shaft 2 flange planes and flow to intermediate bearing 7 and provide lubricant oil.Because Pump wheel shaft is when running up, the lubricant oil that major part sprays from former oil inlet pipe 4 is got back in oil storage casing in the loss of splashing of Pump wheel shaft flange planes, the lubricant oil that can enter intermediate bearing 7 only has seldom, therefore lubrication effect is bad, often makes intermediate bearing 7 can not reach the requirement of regulation working life.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of back pressure type rotor intermediate bearing lubricating fitting of the high lubricating effect for variable speed fluid coupling.
In order to solve the problems of the technologies described above, technological scheme of the present invention is to provide a kind of back pressure type rotor intermediate bearing lubricating fitting, comprise Pump wheel shaft, Pump wheel shaft end is located on variable speed fluid coupling casing by bearing support, intermediate bearing is located on Pump wheel shaft by middle bearing bracket, pump impeller is by middle bearing bracket and intermediate bearing outer ring compact siro spinning technology, pump impeller end cap connects pump impeller, it is characterized in that: the Pump wheel shaft between described bearing support and pump impeller end cap is provided with oil-feed basin, oil-feed basin is provided with oil inlet pipe and lubrication management, oil inlet pipe and lubrication management are all connected with oil storage casing.
Preferably, described oil-feed basin and described bearing support compact siro spinning technology, described oil-feed basin coordinates with described pump impeller end cover clearance.
Preferably, spacer is provided with between described oil-feed basin and described bearing support.
When a kind of back pressure type rotor intermediate bearing lubricating fitting provided by the invention uses, lubricant oil is provided: directly provide lubricant oil by the through hole that the flange of Pump wheel shaft is arranged to intermediate bearing by lubrication management by two road direction intermediate bearings, but because Pump wheel shaft is in High Rotation Speed, only have fraction lubricant oil to enter intermediate bearing from the lubricant oil of lubrication management ejection, fully can not meet lubrication needs; The lubricant oil entered by oil inlet pipe makes to be full of lubricant oil in oil-feed basin, when Pump wheel shaft is when running up, can relatively form the dynamic oil ring that has certain pressure, the lubricant oil back-pressure that the lubricant oil that lubrication management can be sprayed to intermediate bearing by this oil ring splashes excessive because of the Pump wheel shaft impact of High Rotation Speed enters the lubricant oil through hole on Pump wheel shaft and enters intermediate bearing lubricating oil sump, intermediate bearing is enable to obtain good lubrication, thus the equipment use overhaul life is extended, improve equipment use economic benefit.
Device provided by the invention overcomes the deficiencies in the prior art, provides lubricant oil, intermediate bearing is well lubricated, improve the working life of intermediate bearing by two road direction intermediate bearings.

Embodiment
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Fig. 2 is a kind of back pressure type rotor intermediate bearing lubricating fitting schematic diagram provided by the invention, described a kind of back pressure type rotor intermediate bearing lubricating fitting comprises Pump wheel shaft 2, Pump wheel shaft 2 end is fixed on variable speed fluid coupling casing 1 by bearing support 3, intermediate bearing 7 is contained on Pump wheel shaft 2 by middle bearing bracket 8, pump impeller 6 is closely connected by middle bearing bracket 8 and intermediate bearing outer ring 9, and pump impeller end cap 5 is fixedly connected with pump impeller 6.Pump wheel shaft 2 between bearing support 3 and pump impeller end cap 5 is equipped with oil-feed basin 10, oil-feed basin 10 is fixedly mounted on bearing support 3, spacer 11 is housed between oil-feed basin 10 and bearing support 3, and spacer 11 separates interfering with each other of front end rolling bearing lubrication oil and intermediate bearing lubricant oil.It is Spielpassung between oil-feed basin 10 and pump impeller end cap 5.
Composition graphs 3 and Fig. 4, oil inlet pipe 13 and lubrication management 12 oil-feed basin 10 be equipped with, oil inlet pipe 13 is all connected with oil storage casing with lubrication management 12, wherein lubrication management 12 directly provides lubricant oil for intermediate bearing 7, oil inlet pipe 13 provides make-up oil for oil-feed basin 10, ensure to be full of lubricant oil in oil-feed basin 10, and there is certain pressure.
During hydraulic coupler rotor, for ensureing that intermediate bearing 7 operationally can be lubricated fully, lubricant oil is provided: directly provide lubricant oil by the through hole that the flange of lubrication management 12 by Pump wheel shaft 2 is arranged to intermediate bearing 7 by two road direction intermediate bearings 7, but because Pump wheel shaft 2 is in High Rotation Speed, the lubricant oil sprayed from lubrication management 12 only has fraction lubricant oil can enter intermediate bearing 7, fully can not meet lubrication needs; The lubricant oil entered by oil inlet pipe 13 makes to be full of lubricant oil in oil-feed basin 10, when Pump wheel shaft 2 is when running up, can relatively form the dynamic oil ring that has certain pressure, the lubricant oil that lubrication management 12 can be sprayed to intermediate bearing 7 by this oil ring to affect and the lubricant oil back-pressure of splashing excessive enters the lubricant oil through hole on Pump wheel shaft 2 and enters intermediate bearing 7 lubricating oil sump because of the Pump wheel shaft 2 of High Rotation Speed, intermediate bearing 7 is made to obtain good lubrication, thus the equipment use overhaul life is extended, improve equipment use economic benefit.
