In sum, existing oil hydraulic motor all needs to set up the valve block part of extra flushing valve on housing, so complex structure cost height for realizing dashing oil.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of oily device that dashes that need not to increase the valve block structure with regard to the oil hydraulic motor that can realize housing is washed is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of oil hydraulic motor dash oily device, comprise the logical food tray that is installed on the housing, have oil inlet passage and oil discharge passage in the logical food tray, have the drain tap that communicates with the inner chamber of housing on the housing, it is characterized in that: have in the described logical food tray one with described oil discharge passage bypass dash oily passage, should be equipped with control on the sidewall of oily passage and open and close the adjustable spool of degree, have the oilhole that dashes that is communicated with described inner chamber towards oily passage and housing in the described housing towards oily passage.
Above-mentioned L-shaped towards oily passage, the described mounting hole of installing for the adjustable spool that has on the sidewall of oily passage, this mounting hole is the ladder tapped hole, mounting hole is communicated with horizontal channel portion towards oily passage, the adjustable spool is threaded in the mounting hole, the conical surface of the front end of adjustable spool for matching with horizontal channel portion towards oily passage is provided with seal ring between the front portion of adjustable spool and the mounting hole inwall.It is a kind of concrete adjustable valve core structure, this adjustable spool itself is simple in structure, and easy for installation, seal ring is set can prevents that hydraulic oil from leaking from mounting hole, the inner of adjustable spool is a conical surface, can guarantee that adjustable restrictive valve in-core end effectively closes towards oily passage.
For the adjustable spool is locked at certain position, locking nut has been threaded on the above-mentioned adjustable spool that exposes outside housing.
For the hydraulic oil that prevents to wash is gone out from the mating face seepage of logical food tray and housing, above-mentionedly be provided with O-ring seals towards oily passage and between the mating face of oilhole.
Above-mentioned drain tap has two, and one of them drain tap is closed, another unlatching.Two drain taps are set select to use drain tap according to the situation of installing, the convenient oil hydraulic motor of installing.
Compared with prior art, advantage of the present utility model is: should be towards oily device by offering towards oily passage in logical food tray, in housing, offer towards oilhole, and on the sidewall of oily passage, having additional the adjustable spool, just can make full use of oil hydraulic motor itself and recycle fuel-displaced flushing in the process the housing inner chamber, need not additionally to increase flushing valve and flush power source, reduce the overall volume and the energy consumption of oil hydraulic motor, and effectively reduce cost; And the effective impurity in the flushing of hydraulic motor casing, keep cleaning in the housing, and give the cooling of the friction parts in the housing, guarantee the proper functioning of friction parts.
