Description
Technical field
The utility model relates to a kind of moment restriction shaft coupling friction disc test unit, particularly relates to a kind of moment for aerogenerator restriction shaft coupling friction disc test unit.
Background technology
In aerogenerator, mechanical braking device is used to the rotating speed controlling high speed shaft, and the voltage of electricity that the rotating speed control effect of high speed shaft sends, electric current and frequency, thus have impact on power generating quality, the principle of work of mechanical braking device for: utilize several groups of brake flanges on high speed shaft and brake block to hold the velocity of rotation that produced brake torque reduces high speed shaft tightly, so, when aerogenerator works in brake gear, the quality of two direct contact material frictional behaviours directly has influence on the performance of brake gear, the frictional behaviour of friction disc just seems of crucial importance.Frictional behaviour is one of fundamental property of various material, the friction factor of friction disc is again for one group of friction pair, say that merely certain material is that friction factor is nonsensical, the material category of composition friction pair must be indicated, and ambient temperature and humidity is described, load, the test conditions such as speed, and sliding material, so the measurement of friction force must in laboratory conditions and meet certain operating mode.
At present, the friction force experiment of moment restriction shaft coupling is all that the brake flange of aerogenerator brake gear and the friction factor of brake block directly have influence on the serviceable life of braking efficiency and brake block by installing to actual on aerogenerator making for whether reliably detecting.Directly install to actual use on aerogenerator inconvenient, handling and image data difficulty.
Utility model content
The technical problems to be solved in the utility model is to provide one in laboratory conditions, can meet the friction disc performance test of certain operating mode, and method of testing is simple and convenient, the test unit of data reliable moment restriction shaft coupling friction disc performance.
A kind of moment restriction shaft coupling friction disc test unit, comprise support, be arranged on the propulsion system on support, test platform above the gearing be connected with propulsion system and gearing, described propulsion system comprise loading motor, with the wheel box loading motors, there is rotatable positioning gear at described test platform center, described rotatable positioning gear lower end is through test platform connection for transmission device, on described test platform, distance test (DT) Platform center equidistance place is fixed with 2 relative rotatable gear blocks, its distance is less than the ultimate range at the friction flange two ends of moment restriction shaft coupling.
Preferred as one, described gearing comprises support sleeve and is located at the transmission shaft of its inside, described support sleeve upper end joint test platform, and lower end connects gear box, described transmission shaft upper end connects rotatable positioning gear, and lower end connects axle in wheel box.
Preferred as one, the fixed bar that described rotatable positioning gear comprises shaft collar and arranges thereon.
Preferred as one, described test platform be circular, and diverse location is radially provided with 2 tooth holes to the fixing rotatable gear block of above symmetry.
