Abstract
The utility model relates to a cooling device for oil-bath type lubricating cavity bearings, in particular to a cooling device for large-sized pump bearings, belonging to the technical field of mechanical lubrication devices. A cooling coil is installed in an oil tank of an inner cavity of a bearing block, two ends of the cooling coil are communicated with a cooling liquid circulating device arranged outside the bearing block, and the cooling coil which is in spiral winding shape is made from a copper tube. The bearing cooling device is simple in structure and few in expenses increase, can effectively reduce oil bath temperature, prolongs service life of bearings, reduces maintenance cost and has convenient operation.
Description
One, technical field
The cooling unit that the cooling unit, particularly magna pump axon of the utility model bath lubrication chamber bearing holds belongs to mechanical lubrication device technique field.
Two, background technique
At present, in the pump industry, the lubricating system of bearing mainly contains two kinds, grease lubrication and bath lubrication, and grease lubrication is mainly used in the lower medium of fed sheet of a media temperature, and the fed sheet of a media temperature＞more than 85 degree, just need adopt bath lubrication, just can make the equipment smooth running.。Because the operating conditions of pump is comparatively abominable, and be operation continuously in 24 hours, fed sheet of a media is high temperature, corrosion, the abrasion medium, heat usually is passed to bearing by axle, the bigger pump of some bearing diameters particularly, make that the temperature of bearing portion is higher, the temperature of lubricant oil is raise, and heat can't discharge, the rising of bearing temperature, make bearing inner race loosening because of thermal expansion and axle, the outer ring influences the play of bearing because of thermal expansion, and bearing operates under the condition of high temperature for a long time, can influence the working life of bearing, thereby influence the working life of complete machine, increase maintenance cost.Because after the diameter of axle was big, the expense of changing bearing was higher, therefore, reduce the operating temperature of bearing, prolong the problem that becomes a needs solution working life of bearing.
Three, summary of the invention
1, the technical problem that will solve
Thereby the purpose of this new device is to provide a kind of cooling unit that bath lubrication chamber bearing temperature reduces the bearing working temperature that reduces, and can prolong bearing working life, reduces maintenance or changes the spare part cost, improves operation stability of equipment.
2, technological scheme
The utility model is achieved in that in the oil sump of bearing support inner chamber cooling coil is housed that the two ends of cooling coil are communicated with the outer coolant circulation unit that is provided with of bearing support.This described cooling coil adopts copper tube to be prepared into the coiled coil shape.By the cooling water cooling that circulates, allow flowing cold water that the heat in the oil sump is taken away during work, thereby reach the effect that reduces the bearing bore temperature.
3, beneficial effect
Cooling unit described in the utility model is than the pump of traditional bath lubrication, set up a water composite cooling pipe, under the situation that need not change any part, can realize the medium that delivery temperature is higher, effectively prolong the working life of bearing, reduce the effect of maintenance cost, easy to operate, the utility model device is compared with conventional apparatus has stronger operability.
Four, Figure of description
Fig. 1 is a structural representation of the present utility model.
Among the figure: bearing support 1, rotating shaft 2, bearing 3, cooling coil 4, bearing support inner chamber 5.
Five, embodiment
Referring to Fig. 1, the utility model does not change existing bath lubrication pump foundation structure, and cooling coil 4 is housed in the oil sump of bearing support inner chamber 5, and this cooling coil 4 adopts copper tube to be prepared into the coiled coil shape, to increase heat diffusion area.The two ends of cooling coil 4 pass the head that is tightly connected on the bearing support fuel outlet shrouding, are communicated with the outer cooling water circulating device that is provided with of bearing support (not drawing among the figure).
Claims (2)
1. bearing cooling unit is characterized in that: in the oil sump of bearing support inner chamber cooling coil is housed, the two ends of cooling coil are communicated with the outer coolant circulation unit that is provided with of bearing support.
2. by the described bearing cooling unit of claim 1, it is characterized in that: cooling coil adopts copper tube to be prepared into the coiled coil shape.
