Abstract
The utility model relates to a thrust bearing component for blades, which comprises a bearing. The utility model is characterized in that a bearing seat is a three-side seal type; one side of an opening of the bearing seat is assembled with a nut; a sealing ring is assembled between the nut, and the opening end of the bearing seat; an oil adding hole is arranged on the nut; and a plug screw is assembled at an inlet of the oil adding hole. The utility model has the advantages of good bearing lubricating oil sealing, no leakage, improved lubricating effect, prolonged service life and convenient oil adding maintenance.
Description
Technical field
The utility model belongs to a kind of fan part, particularly a kind of blade thrust bearing component.
Background technique
In existing moving accent axial-flow blower structure, blade thrust bearing plays crucial effects in the adjusting of moving vane.The moving bearing lubrication mode of axial-flow blower of transferring is lubricated for the thin oil oil sump, in wheel hub chamber, sharf thrust-bearing place, and the lubricant oil of packing into, when wheel hub rotated, centrifugal force got rid of oil to place, bearing place, and bearing is lubricated.But owing to have the gap between sharf and wheel hub axis hole, and sealing is difficult to lubricant oil is sealed, and causes leaking along sharf.Thereby the reduction lubrication effect influences working life.
The model utility content
The purpose of this utility model provides a kind of blade thrust bearing group, can fine the bearing lubrication oil seal not produced leakage.Improve lubrication effect, increase the service life.
The purpose of this utility model is achieved by the following technical solution: it comprises bearing, it is characterized in that: bearing support is three face seal formulas, at bearing support opening one side assembling nut, assemble seal ring between nut and the bearing support opening end, the repairing hole is set, at the ingress in repairing hole assembling plug screw on nut.
The utility model has the advantages that: can fine the bearing lubrication oil seal not produced leakage, improve lubrication effect, increase the service life, repairing is easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, the utility model concrete structure is as follows: bearing support 2 is three face seal formula structures, assembling bearing 3 in the bearing support 2, at bearing support opening one side assembling nut 6, assembling O RunddichtringO 5 and packing ring 4 constitutes closed cell between nut 6 and bearing support opening end, makes the lubricant grease of bearing not to external leakage, circumferentially be evenly equipped with 3 repairing holes 8 in nut 6 upper edges, so that when maintenance replenished grease.At the ingress in repairing hole 8 assembling plug screw 7.Inject lubricant grease by this hole.
