Description
Technical field
The utility model belongs to machining technology field, more particularly to wind power yaw friction sheet torque test platform.
Background technology
Any machine components or instrument, in use, often to be acted on by various forms external force, such as crane
On cable wire, acted on by suspension pulling force；Connecting rod on diesel engine, in passing power, the not only effect of under tension,
But also acted on by impulsive force；Axial workpiece will be by moment of flexure, the effect etc. of torsion, and these metal materials are in outer masterpiece
It is referred to as the mechanical property of metal material with features such as lower shown elasticity, intensity, hardness, plasticity and toughness.
At present, the detection of wind power yaw friction sheet mechanical property is also without a room temperature mechanics that is more complete and establishing one's own system
Performance detecting system, for used monitor station because its design structure is unreasonable, material is not inconsistent standardization, cause efficiency it is low, adapt to
Property it is poor, operation it is dangerous inconvenient the features such as thus can not be deeply by user's pro-gaze.
The content of the invention
In order to solve above-mentioned problem, the utility model provides a kind of wind power yaw friction sheet torque test platform, this
Kind torque test platform easy-to-operate, easily controllable and identical with actual use technique, environmental benefit is good.
To achieve these goals, the technical solution adopted in the utility model is：Wind power yaw friction sheet torque test platform,
Including：Support, master control system, stepper motor, ball screw, pressure sensor, guide rail, bracket, brake, it is characterised in that
The master control system, stepper motor are located in base box body；
A switch is provided with the left of the support, the switch is connected with master control system；
The stepper motor is connected with support upper end ball screw one end；
The ball screw other end is connected with described pressure sensor one end；
The pressure sensor other end connects a support, and the pedestal lower end is connected with the guide rail being fixed on support；
The support is provided with a connector, and brake disc is fixed on support by connector；
The bracket is fixed on support, and the brake is arranged on bracket, and brake has two driftage frictions up and down
Piece.
The specific operating procedure of wind power yaw friction sheet torque test platform：Brake disc is fixed on by support by connector
On, testing stand master control system control stepper motor, driving ball screw drives support to carry out oscillating rectilinear motion on guide rail,
Bracket upper brake is received through the hydraulic action that piston comes through oil pipe conveying, and making brake, two driftage friction plates press to up and down
Brake disc produces friction catch, and pressure sensor gathers load-carrying ability data feedback to master control system.
The utility model wind power brake torque test platform easy-to-operate, it is easily controllable, and with actual use technique
Identical, the speed of service is fast, powerful, and environmental benefit is good, and simple in construction, practical.
It is the utility model wind power yaw friction sheet torque test platform schematic diagram to illustrate Fig. 1.
In figure, 1, support；2nd, switch；3rd, ball screw；4th, pressure sensor；5th, support；6th, connector；7th, guide rail；8、
Brake；9th, bracket；10th, brake disc.
The utility model is described in further detail with reference to embodiment for embodiment.
In embodiment, switch is opened（2）, master control system startup, hydraulic station unlatching, hydraulic station pressure is adjusted, it is general dynamic
Rub loine pressure 2.4MPa, static friction pressure 16MPa, brings into operation, now adjusts support（5）To guide rail（7）Starting point, selection
Program, the dynamic friction speed of service：180 mm/min, 245 mm of test trip/one-stroke, set cycle-index.Static friction is transported
Scanning frequency degree：50 mm/min, 60 mm of test trip/one-stroke, set cycle-index.Pass through connector（6）By brake disc
（10）It is fixed on support（5）On, master control system Driving Stepping Motor is operated, and stepper motor drives ball screw（3）Make branch
Frame（5）Drive brake disc（10）In guide rail（7）Upper carry out oscillating rectilinear motion, brake（8）Installed in bracket（9）On, system
Dynamic device（8）The hydraulic action that two upper and lower driftage friction plates are come by piston through oil pipe conveying, presses to brake disc（10）Produce
Friction catch, pressure sensor（4）Collection load data feeds back to master control system, so as to complete the mechanics examination of driftage friction plate
Test.
Take and tested with a batch of driftage friction plate finished product in original constant speed formula friction Detecting data with the utility model
Contrast experiment is carried out on platform, traditional constant speed formula rubs Detecting data due to the limitation of equipment, can only be in whole driftage friction
Sub-fraction test piece is taken on piece, it is impossible to the use technique of the whole driftage friction plate of reflection；The speed of constant speed formula friction Detecting data
Degree is certain（480~500r/min）, have larger gap with actual use, constant speed formula friction Detecting data normal pressure passes through tune
Save sliding weight of steelyard adjustment of weight pressure, maximum pressure 0.9Mpa;And the utility model wind power yaw friction sheet torque test platform, examination
It is identical with actual use brake bush to test object, without taking block sample, by adjusting hydraulic station system（1-20Mpa）
Pressure meets the pressure used under actual condition, and speed is adjustable.
In summary, the utility model wind power yaw friction sheet torque test platform being capable of its power under real simulation actual condition
It is high to learn the performance detection degree of accuracy.
