Description
Technical field
The utility model relates to a kind of bearing housing, particularly a kind of integrated type oil lubrication fan bearing case.
Background technique
Along with development of economic construction, to use blower fan at present, will use blower fan to carry out ventilation, in supporting fire-protection equipment, also will use the blower fan of eliminating smog as building, megastore, office building, purification factory building etc. in many places.And a critical piece in the blower fan is the bearing support of carrying fan blade, for high speed rotating and the operation for a long time that keeps blower fan, the bearing support that general blower fan uses need be lubricated, the bearing support of more slow-revving blower fan generally adopts lubricant grease to be lubricated, and the employed bearing support of blower fan at a high speed just must use the bearing support of oil lubrication, this is because high speed rotating can produce the heat intensification, therefore need to use oil lubrication to improve lubricated effect, the heat that also pivot friction is produced is taken away simultaneously, to keep the long-play of blower fan.But the bearing support of oil lubrication blower fan is because the oil-bearing structure complexity in the oil lubrication is unreasonable at present, cause the volume of bearing support bigger, improved production cost of products greatly, and make the overall weight of blower fan increase, also caused in blower fan is installed, need blower fan be installed with big stronger bearing structure, increase the difficulty of blower fan in using installation process greatly.
Summary of the invention
The purpose of this utility model is to solve oil lubrication fan bearing case complicated unreasonable existing the problems referred to above when the design oil-bearing structure in the prior art, and a kind of integrated type oil lubrication fan bearing case is provided.The utility model designs a kind of integrated type oil lubrication fan bearing case, comprise bearing housing, main shaft, a pair of deep groove ball bearing, pair of bearings case side cover, it is characterized in that: a deep groove ball bearing is respectively arranged in the both sides of bearing housing, the outer ring of deep groove ball bearing and bearing housing inwall close-fitting, the inner ring of deep groove ball bearing and main shaft outside close-fitting, the inner ring that the fastening deep groove ball bearing of round nut is arranged on main shaft, on the inner ring outside of bearing housing side cover, be embedded with a rotating seal ring, rotating seal ring contacts with main shaft, in the middle of the inner ring of bearing housing side cover, be embedded with skeleton running shaft lip oil sealing, skeleton running shaft lip oil sealing contacts with main shaft, in the inner ring inboard of bearing housing side cover is the oil groove of an indent, one draining hole is arranged in the bottom of oil groove, and the draining hole is communicated with oil groove and bearing housing inner chamber.At the bearing housing top oil hole is arranged, the air filtering plug is arranged on the oil hole.In the bearing housing bottom drain line is arranged, drain line is connected to valve.The utility model has the advantages that the lubricity that can improve the fan bearing case, dwindle the volume of bearing housing greatly, simplified the structure of bearing housing.

Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the A place structural representation of the utility model accompanying drawing 1,
Accompanying drawing 3 is the B place structural representation of the utility model accompanying drawing 1.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise bearing housing 1 among the figure, main shaft 2, a pair of deep groove ball bearing 3, pair of bearings case side cover 4, it is characterized in that: a deep groove ball bearing 3 is respectively arranged in the both sides of bearing housing 1, the outer ring of deep groove ball bearing 3 and bearing housing 1 inwall close-fitting, the inner ring of deep groove ball bearing 3 and main shaft 2 outside close-fittings, the inner ring that round nut 5 fastening deep groove ball bearings 3 are arranged on main shaft 2, on the inner ring outside of bearing housing side cover 4, be embedded with a rotating seal ring 6, rotating seal ring 6 contacts with main shaft 2, in the middle of the inner ring of bearing housing side cover 4, be embedded with skeleton running shaft lip oil sealing 7, skeleton running shaft lip oil sealing 7 contacts with main shaft 2, in the inner ring inboard of bearing housing side cover 4 is the oil groove 8 of an indent, one draining hole 9 is arranged in the bottom of oil groove 8, and draining hole 9 is communicated with oil groove 8 and bearing housing 1 inner chamber.At bearing housing 1 top oil hole 10 is arranged, air filtering plug 11 is arranged on the oil hole 10.In bearing housing 1 bottom drain line 12 is arranged, drain line 12 is connected to valve 13.
During use, with the oil hole 10 of oil can lubricant oil is injected in the bearing housing 1 from bearing housing 1 top, being immersed into deep groove ball bearing 3 bottoms up to lubricant oil gets final product, after blower fan rotates, lubricant oil is thrown on the main shaft 2 with the rotation of deep groove ball bearing 3, and can move along with the bearings at both ends case side cover 4 of main shaft 2 toward bearing housing 1, after running into the skeleton running shaft lip oil sealing 7 of the inner ring that is embedded in bearing housing side cover 4, most lubricant oil is dumped in the indent oil groove 8 of inner ring of bearing housing side cover 4, draining hole 9 along oil groove 8 bottoms is flowed back in the bearing housing 1, and the lubricant oil of minimum part still leaks along main shaft 2, the rotating seal ring 6 that is embedded on the inner ring outside of bearing housing side cover 4 stops, coated grease 14 owing to filling up, also can slow down leaking of lubricant oil in rotating seal ring 6 inboards.
And circuit lubricant oil can be taken away the heat of bearing rapidly, guarantees the proper functioning of integrated type oil lubrication fan bearing case.
