Embodiment
Below against accompanying drawing, by the description to embodiment, to the embodiment of the present invention such as involved each structure
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of part, construction, each several part etc. are made further
Detailed description.
As shown in Figure 1, 2, this rubber wearability detection means includes motor 1, friction pulley 3, rubber retention mechanism and pressure
Applying mechanism, the center of friction pulley 3 is fixed on motor 1, and motor 1 drives friction pulley 3 to rotate, and digital display is set on motor 1
Table 2 shows rotating speed, and rubber 4 to be checked is fixed on rubber retention mechanism, and pressure applying mechanism is connected with rubber retention mechanism, pressure
Applying mechanism applies pressure to rubber retention mechanism.
As shown in Fig. 2 above-mentioned rubber retention mechanism includes fixed mount 5, firm banking 6 and fastening handle 7, firm banking 6
It is fixed on bottom plate, fixed mount 5 is fixed on firm banking 6 vertically, and fixed mount 5 is set in face of friction pulley 3,7 sets of fastening handle
On fixed mount 5.
As shown in Fig. 2 pressure applying mechanism includes forcing press push rod 8, press frame 9, adjusting pressuring handle 11, forcing press machine
The two ends of body 9 set forcing press push rod 8 and adjusting pressuring handle 11, and the end of forcing press push rod 8 is withstood on fixed mount 5, forcing press machine,
Pressure gauge 10, the pressure of display forcing press push rod 8 are set on 9.
During test, motor 1 can provide smart metastable torque output, while the rotating speed of servomotor 1 can be adjusted arbitrarily,
It is easy to the situation detection to various differentiated friction speed.In addition, intuitively can effectively reflect servomotor 1 by digital display meter 2
The actual parameter such as operating voltage U, electric current I and rotating speed n.Friction pulley 3 is made of the higher alloy steel products of wear resistence, is rubbed
The straight-line groove simulation rubber on 3 surfaces is taken turns in corner angle body surface friction factor, increases friction coefficient μ.
In use, the note of rubber 4 to be checked is invested on fixed mount 5, by fastening handle 7 by rubber secured fit in fixed mount 5
Surface, fixed mount 5 is installed on by way of being hinged on firm banking 6, so as to realize the pressure of rubber 4 to be checked and friction pulley 3
Regulation.
Pressure applying mechanism is that pressure is provided by a special forcing press, and forcing press push rod 8 can be with adjusting pressuring handle
11 rotation carries out telescopic moving and the increase and decrease of pressure regulation, and various different pressures are realized by manual rotation adjusting pressuring handle 11
The detection of power needs, meanwhile, pressure N during detection can be intuitively known very much by pointer pressure gauge on pressure gauge 10.
Summary, the effective technology parameter that we detect is as follows：
