Having the cylindrical structural in fan shaft hole centered by described water-cooled oil lubrication lobe gearing, separation body interior is divided into upper and lower two cooling chambers, has cooling water inlet and coolant outlet respectively, so can increase the rate of heat transfer of water-cooled oil lubrication separation.
Preferably, described cooling water inlet is respectively positioned on cooling chamber bottom side edge, coolant outlet is respectively positioned on cooling chamber upper side edge, so guarantees that cooling water is full of whole cooling chamber toward top bottom cooling chamber, makes cooling water and water-cooled oil lubrication separation carry out sufficient heat exchange.
It is further preferred that described cooling entrance and coolant outlet lay respectively at the offside of cooling chamber, it is ensured that cooling water keeps growing most in cooling chamber, makes cooling water heat exchange evenly, more fully.
The diameter in described fan shaft hole is more than the diameter of fan shaft.
Concrete, the two ends up and down in described fan shaft hole have the screens of gland respectively and seal the screens of bearing, and wherein the diameter of gland screens is more than sealing the diameter of bearing screens more than the diameter in the middle part of fan shaft hole.
Described fan shaft is embedded in fan shaft hole by upper-lower seal bearing, therefore can form a cavity between rotating shaft and water-cooled oil lubrication separation.
Described upper-lower seal Bearing outer is equipped with gland, is better fixed by bearing by gland, it is prevented that bearing is vibration vertically.
Lubricating oil is filled in cavity between described upper-lower seal bearing, reduced the friction of rotating shaft place by oil addition, prevent rotating shaft corrosion simultaneously, secondly, lubricating oil also can meet the demand of heat transfer, and lubricating oil and the combination sealing bearing simultaneously can increase the sealing property of equipment.
The beneficial effects of the present invention is: heat-treatment furnace blower fan and fan blade connecting end axle damage after scrapping, only need to change water-cooled oil lubrication separation drive mechanism or change the axle of water-cooled oil lubrication separation drive mechanism, before so changing, monoblock type heat-treatment furnace blower fan causes whole Fans to scrap due to the damage of fan blade end axle, both easy to maintenance and the cost of heat-treatment furnace user can be reduced, improve the utilization ratio of resource, there is very big practical value. Secondly, the features simple structure of the present invention, parts are less, it is simple to parts are changed in maintenance.
Secondly, equipment sealing property is made to significantly improve by arranging water-cooled oil lubrication sealed compartment, the sealing demand of carburizer or vacuum drying oven can be met, and by coolant and rotating shaft isolation, by lubricating oil and shaft contacts, sealing property can be increased, be also prevented from the corrosion of rotating shaft simultaneously, increase the service life of equipment.
