Dynamic part smooth rotation.In rotating part high speed rotation, many heats can be generated with guide bearing friction, it is necessary to be carried out pair
Guide shoe is cooled down, therefore guide bearing needs heat dissipation design.
At present about the cooling of guide bearing, use is guide bearing cooling method of outer circulation on large-sized unit mostly, but
It is since cooling oil circulation route is unsmooth, guide bearing temperature is relatively high, when guide bearing block is burned out since temperature is excessively high, just can only
By forced-stopping machine, huge economic loss is caused.Traditional guide bearing needs to design complicated box-type water-cooled but device, not only significantly
Motor cost and complexity are increased, the demand of Industrial cleaning facility water has also been increased considerably；Especially in inland drought and water shortage region,
The operation expense of motor guide bearing is increased, and local valuable water resource is caused to waste.
Summary of the invention
The technical problems to be solved by the invention are in view of the above shortcomings of the prior art, to provide outside a kind of guide bearing
Circulated sprinkling cooling structure, the present invention use spraying cooling, instead of the thrust rotor oilhole circulating cooling of traditional approach, directly
Cooling oil is led to guide bearing, circulation route shortening is simultaneously more direct.The present invention uses cooling oil spraying cooling, will not be to dry
The water resource of non-irrigated water-deficient area preciousness causes to waste.
The technical solution of the present invention is as follows: a kind of guide bearing outer circulation spraying cooling structure, comprising: tee tube, branch pipe, flow
Pump, guide bearing, jet pipe, thrust rotor, endless tube, spray orifice and outer circulating tube, it is characterised in that: outer circulating tube one end setting
There is branch pipe, the branch pipe and outer circulating tube are connected with each other, and described branch pipe one end is provided with tee tube, the tee tube and branch pipe phase
It connects, flow pump is provided on the outer circulating tube, the flow pump and outer circulating tube are connected with each other, and the endless tube is set to
Above guide bearing, the endless tube and the outer circulating tube other end are connected with each other, and the endless tube side is provided with jet pipe, described
Jet pipe is mutually permanently connected with the endless tube, and spray orifice is provided on the jet pipe, and the guide bearing side is provided with thrust and turns
Son.
Further, there are three the spray orifice settings.
Further, the material of the tee tube is stainless steel.
Further, the material of the endless tube is stainless steel.
The beneficial effects of the present invention are:
1. the present invention uses spraying cooling, instead of the thrust rotor oilhole circulating cooling of traditional approach, directly cooling
Oil leads to guide bearing, and circulation route shortening is simultaneously more direct.The present invention uses cooling oil spraying cooling, will not be to drought and water shortage
Regional valuable water resource causes to waste.
2. three spray orifices are arranged in the present invention from top to bottom on jet pipe, keep entire guide bearing cooling more uniform, accounting for
10-15 DEG C can be reduced according to the running temperature of comparable size condition down guide bearing bush, has the advantages that cooling effect is uniform.
3. the present invention draws tee tube branch using branch pipe in outer circulating tube one end, and the control of setting flow pump is drawn wherein
To the cooling oil of guide bearing, and endless tube is set on guide bearing, can make that pressure is balanced and structure is safe and reliable.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Wherein: 1, tee tube 2, branch pipe 3, flow pump
4, guide bearing 5, jet pipe 6, thrust rotor
