Description

Moment restriction shaft coupling friction disc test unit
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.
The beneficial effects of the utility model are:
1, this device utilizes principle of moment balance indirect inspection friction force, collection balance friction force, snap-in force, relative sliding velocity, analyze the frictional behaviour of friction disc, specify the character of material, for estimating the life-span of aerogenerator braking components, the design of aerogenerator provides foundation.
2, this device operates real working condition close to aerogenerator, and to measure under different snap-in force and friction speed friction factor situation of change under two kinds of operating modes respectively, data are true and reliable.
Accompanying drawing explanation
Fig. 1 is the front view of moment restriction shaft coupling friction disc test unit;
Fig. 2 is the vertical view of moment restriction shaft coupling friction disc test unit;
The structural representation of mounting torque restriction shaft coupling when Fig. 3 is the friction disc test unit test of moment restriction shaft coupling.
Embodiment
Shown in Fig. 1, moment restriction shaft coupling friction disc experimental provision, comprise support 1, be arranged on the propulsion system on support 1, test platform 5 above the gearing be connected with propulsion system and gearing, described propulsion system comprise the wheel box 3 loading motor 2 and load motors, there is rotatable positioning gear at described test platform 5 center, the fixed bar 8 that rotatable positioning gear comprises shaft collar 7 and arranges thereon, rotatable positioning gear lower end is through test platform 5 connection for transmission device.On test platform 5, equidistance place, distance test (DT) platform 5 center is fixed with 2 relative rotatable gear blocks 6, and its distance is less than the ultimate range at the friction flange two ends of moment restriction shaft coupling.
Gearing comprises support sleeve 4 and is located at the transmission shaft of its inside, and support sleeve 4 upper end is connected by screw test platform 5, and lower end connects gear box 3, and transmission shaft upper end connects rotatable positioning gear, and lower end connects axle in wheel box 3.
Shown in Fig. 2, test platform 5 is circular, and diverse location is radially provided with 2 tooth holes 12 to above symmetrical fixing rotatable gear block 6.
Shown in Fig. 3, moment restriction shaft coupling is installed on moment restriction shaft coupling friction disc test unit, rotatable gear block 6 is fixed on the tooth hole 12 of fixing rotatable gear block 6, this rotatable gear block 6 fixes the moment restriction shaft coupling of different size by the anglec of rotation and the method that is fixed on different tooth holes 12, when start-up loading motor 2, wheel box 3 speed change drives the uniform rotation together of rotatable positioning gear through transmission shaft conduction, rotatable positioning gear drives moment restriction shaft coupling to rotate, because rotatable gear block 6 stops that friction flange 11 rotates, rotatable positioning gear drives moment restriction shaft coupling miscellaneous part rotate together thus make friction disc 10 produce Relative friction, measure the performance of friction disc 10.This device controls the frictional behaviour of friction speed testing friction sheet 10 at various speeds especially in higher speed situation by wheel box 3; By the frictional behaviour of method testing friction sheet 10 in the especially larger snap-in force situation of different snap-in force in moment restriction shaft coupling upper end pressurization.
Above-mentioned explanation is illustrative rather than restrictive.Can recognize that many kinds of the present invention change and distortion by above-mentioned explanation those skilled in the art, it also will drop within the spirit and scope of the invention.
