Specific implementation mode
Below in conjunction with attached drawing, the present invention is described in detail.
As shown in Figure 1, the purpose of the present invention be provide it is a kind of can be by the novel abrasion of the automatic loaded load of electromagnetic force
Machine, the deflection angle that deflection angle motor (1) is used for controlling grinding wheel (9) keep rubber tire sample (10) friction abundant, deflection angle motor (1)
There are bolt hole in both sides, are bolted on upper bracket (2), have between deflection angle motor (1) axis and upper bracket (2) bearing and
Axis is rotated synchronously with rotary-tray (7), and active motor (8) is bolted on rotary-tray (7), and grinding wheel (9) is actively
Wheel is rotated synchronously with active motor (8) axis, achievees the purpose that wear away rubber tire sample (10).
Rubber tire sample (10) is driven wheel, by the frictional rotation between grinding wheel (9), grinding wheel (9) and by copper product structure
At intermediate supports axis magnetic conductivity it is low, temperature hardly changes under conditions of changes of magnetic field, metal wheel hub magnetic conductivity
Height, in changes of magnetic field, temperature increases, and heat is passed to the table of rubber tire sample (10) inside rubber tire sample (10)
Face, it is consistent with the tyre temperature field of truth work, measuring accuracy is improved, metal wheel hub periphery is with teeth, increases and glue
The friction of wheel sample (10) prevents opposite slide.
Changing magnetic field is generated around electromagnetic oven (3), makes heat inside metal wheel hub and leads to rubber tire sample (10) surface
Temperature increases, and temperature sensor (4) detects rubber tire sample (10) surface temperature, when surface temperature reaches rated value, electromagnetic oven
(3) stop being powered, and start active motor (8), abrasion machine is made to start to work.
L-type support (11) is relatively fixed with intermediate supports axis, and L-type support (11) passes through screw hole and pressure sensing thereon
Screw on device (12) is matched and then is connected with pressure sensor (12), and pressure sensor (12) passes through screw and lower end iron prop
(13) screw hole on coordinates and then is connected with iron prop (13), and power can be passed to L by pressure sensor (12) from iron prop (13)
Type holder (11) and then pass to rubber tire sample (10).
After driving shaft starts startup, start to be connected with alternating current on conducting wire (6), the lower end of iron prop (13) occurs and electromagnet
(14) the identical polarity in upper end, when electric current slowly increases, iron prop (13) start along guide rail (5) suspend, electromagnet (14) and
Iron prop no longer contacts with each other between (13), and with the increase of electric current, the distance between iron prop (13) and electromagnet (14) increase, when
After grinding wheel (9) and rubber tire sample (10) contact with each other, magnetic repulsion that iron prop (13) is subject to becomes gravity and elastic force from gravity
With joint efforts, when reaching rated value with joint efforts, electric current no longer increases, and makes grinding wheel (9) and rubber tire by pressure sensor (12) later
Pressure between sample (10) is constant.
Pressure sensor (12) is transferring element and to experience component, is connect thereon with L-type support (11), under have iron prop
(13) it connects, it is whole to be slided on sliding rail, the magnetic repulsion that iron prop (13) is subject to is transmitted on rubber tire sample (10), when pressure passes
When the pressure that sensor (12) detects is less than rated value, electric current increases, and when the pressure detected is more than rated value, electric current subtracts
It is small, so that the pressure that rubber tire sample (10) is subject to is in dynamic equilibrium.
