The transmission of variable speed fluid coupling input and output power is mainly finished by pump impeller in the rotor and turbine assembly.Pump wheel shaft is connected an intermediate bearing (spheric roller bearing) and is connected and to make diaxon be in same central position with turbine shaft, when pump impeller, turbine work, intermediate bearing is subject to the frictional force that pump impeller and turbine rotation round power and gravity produce, and therefore must be arranged the good lubricated guarantee fluid coupling normal work and use overhaul life.
The existing lubricating fitting that is applied to variable speed fluid coupling lubrication system intermediate bearing mainly is comprised of former oil inlet pipe 4, Pump wheel shaft 2, intermediate bearing 7, intermediate bearing sleeve 8 etc. as shown in Figure 1.Pump wheel shaft 2 ends are fixed on the variable speed fluid coupling casing 1 by bearing support 3, intermediate bearing 7 is contained on the 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 that is connected with the oil storage casing is equipped with in pump impeller end cap 5 outsides.
In variable speed fluid coupling when work,, lubricant oil is by equally distributed oil through on the former oil inlet pipe 4 directive Pump wheel shafts 2 flange planes and flow to intermediate bearing 7 lubricant oil is provided.Because Pump wheel shaft is when running up, most of lubricant oil from former oil inlet pipe 4 ejections splashes on Pump wheel shaft flange plane to run off and gets back in the oil storage casing, the lubricant oil that can enter intermediate bearing 7 only has seldom, therefore lubrication effect is bad, often so that intermediate bearing can not reach the requirement of regulation 7 working lifes.
Summary of the invention
The technical problem to be solved in the present invention provides 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 provides a kind of back pressure type rotor intermediate bearing lubricating fitting, comprise Pump wheel shaft, the Pump wheel shaft end is located on the variable speed fluid coupling casing by bearing support, intermediate bearing is located on the Pump wheel shaft by middle bearing bracket, pump impeller closely is connected with the intermediate bearing outer ring by middle bearing bracket, the pump impeller end cap connects pump impeller, it is characterized in that: the Pump wheel shaft between described bearing support and the pump impeller end cap is provided with the oil-feed basin, the oil-feed basin is provided with oil inlet pipe and lubrication management, and oil inlet pipe and lubrication management all are connected with the oil storage casing.
Preferably, described oil-feed basin closely is connected with described bearing support, and described oil-feed basin cooperates with described pump impeller end cover clearance.
Preferably, be provided with spacer between described oil-feed basin and the described bearing support.
When a kind of back pressure type rotor intermediate bearing lubricating fitting provided by the invention uses, provide lubricant oil by two road direction intermediate bearings: directly provide lubricant oil by the through hole that arranges on the flange of lubrication management by Pump wheel shaft to intermediate bearing, but because Pump wheel shaft is in High Rotation Speed, only have fraction lubricant oil can enter intermediate bearing from the lubricant oil of lubrication management ejection, can not fully satisfy lubrication needs; The lubricant oil that enters by oil inlet pipe makes in the oil-feed basin and is full of lubricant oil, when Pump wheel shaft when running up, can relatively form the dynamic oil ring with certain pressure, the lubricant oil through hole that the lubricant oil back-pressure that the lubricant oil that this oil ring can spray to lubrication management intermediate bearing splashes excessive because of the Pump wheel shaft impact of High Rotation Speed enters on the Pump wheel shaft enters the intermediate bearing lubricating oil sump, make intermediate bearing can access good lubrication, thereby so that equipment uses the overhaul life to prolong, raising equipment uses economic benefit.
Device provided by the invention has overcome the deficiencies in the prior art, provides lubricant oil by two road direction intermediate bearings, and it is well lubricated that intermediate bearing can be accessed, the working life of having improved intermediate bearing.

Embodiment
For the present invention is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
Fig. 2 is a kind of back pressure type rotor intermediate bearing lubricating fitting schematic representation 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 ends are fixed on the variable speed fluid coupling casing 1 by bearing support 3, intermediate bearing 7 is contained on the 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 the bearing support 3, between oil-feed basin 10 and the bearing support 3 spacer 11 is housed, spacer 11 is separated interfering with each other of front end rolling bearing lubrication oil and intermediate bearing lubricant oil.Be Spielpassung between oil-feed basin 10 and the pump impeller end cap 5.
In conjunction with Fig. 3 and Fig. 4, oil inlet pipe 13 and lubrication management 12 are housed on the oil-feed basin 10, oil inlet pipe 13 is connected with lubrication management and all is connected with the oil storage casing, 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, guarantee to be full of lubricant oil in the oil-feed basin 10, and have certain pressure.
