Influenced by tilting moment, sealing system has to that certain pressure can be born, and could realize effectively sealing, the validity of sealing
The normal operation of strong influence bearing.
The content of the invention
In order to reach bearing sealed ring with preferable voltage endurance capability and then realize effectively sealing, the purpose of the present invention is carry
For a kind of wind power bearing sealing ring voltage endurance capability test fixture and method.
To achieve these goals, the technical solution adopted in the present invention is：Wind power bearing sealing ring voltage endurance capability is tested
Frock, including bearing outer ring, bearing inner race, the sealing ring being arranged between outer ring and inner ring, uniformly sets on inner ring internal diameter side wall
There are some oilholes, be tightly connected a triple valve on an oilhole wherein, a triple valve wherein valve port is connected with oilhole, one
Grease filling system is connected on valve port, principal pressure table is connected on the 3rd valve port of triple valve；
A pressure gauge is further respectively had in the oil-hole location close to connection principal pressure table both sides, for monitoring；
The principal pressure table is tightly connected with being used at triple valve valve port；
Using sealed connection between the pressure gauge and respective oilhole；
The application method of the detecting tool is：
Including static detection and dynamic detection two parts；The resistance to of sealing ring is quantitatively detected by pressure gauge, triple valve, grease filling system
Pressure energy power, specific steps：
Sealing ring is installed on the bearing that assembling is completed, first to dress fat at the beginning of bearing filling 70% before detection, in bearing inner ring interior diameter
An oilhole on connect triple valve, the triple valve other end connects grease filling system, then principal pressure table is connected on triple valve；
A pressure gauge is connected respectively at the oilhole at the both ends of the oilhole of connection triple valve, then seals remaining oilhole by screw
Firmly, prevent pressure leakage, complete preparation；
Greasing is carried out into bearing by grease filling system, with the injection of grease, the increase of Bearing inner pressure, principal pressure table numerical value
Can gradually it increase, the indicating value change of close observation principal pressure table at this time and the deformation of sealing position；
When pressure exceedes the maximum voltage endurance capability of sealing ring, sealing position can deform, and sealing ring can deviate even therewith
Depart from bearing, at this time grease leakage；
The maximum pressure monitored before grease leakage is exactly the maximum voltage endurance capability of detected sealing ring；
If necessary to test dynamic pressure, then another lasso is rotated while greasing.
It is of the invention to be using beneficial effect caused by above-mentioned technical proposal：Reach bearing sealed ring with preferable pressure-resistant
Ability and then realization effectively sealing, meet the requirement of wind electricity change paddle and yaw bearing to sealing voltage endurance capability.
