Described first speed change belt wheel comprises the first fixed wheel sheet be fixed on machine shaft, coordinate the first fixed wheel sheet that the spaced first movable pulley sheet with the first fixed wheel sheet is installed on machine shaft, described first movable pulley sheet connects elastic component, and described first movable pulley sheet moves the diameter of change first speed change belt wheel along machine shaft;
Described second speed change belt wheel comprises the second fixed wheel sheet be fixed on machine shaft, coordinate the second fixed wheel sheet that the spaced second movable pulley sheet with the second fixed wheel sheet is installed on machine shaft, described second movable pulley sheet connects top and stretches device, and device push-and-pull second movable pulley sheet moves change second speed change belt wheel diameter along machine shaft is stretched on described top.
Especially, described elastic component comprises the installation shaft be arranged within machine shaft, and one end of described installation shaft is provided with spring, and the other end is arranged on the first movable pulley sheet by nut.
Especially, described top is stretched the top that device comprises the outside being installed on the second movable pulley sheet and is stretched oil cylinder, and the piston rod that oil cylinder is stretched on described top connects the second movable pulley sheet, and described top is stretched oil cylinder and connected oil cylinder control box.
Especially, described first movable pulley sheet is installed on the outside of the first fixed wheel sheet, and described second movable pulley sheet is installed on the outside of the second fixed wheel sheet.
Beneficial effect of the present invention is, described shaft-type stepless speed change device for adhesive tape fatigue testing machine has installed the first speed change belt wheel and the second speed change belt wheel that two can change pulley diameters in time, when the pulley diameters of the second speed change belt wheel becomes large in process of the test, because the length testing adhesive tape is constant, therefore the pulley diameters of the first speed change belt wheel just diminishes, when the pulley diameters of the second speed change belt wheel diminishes, then the pulley diameters of the first speed change belt wheel becomes large, thus realizes electrodeless variable-speed.Compared with testing with the speed change utilizing electrical motor gearshift to realize adhesive tape of prior art, closer to the actual type of service of adhesive tape, for the test of adhesive tape improves more reliable test data.

Embodiment
Refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of shaft-type stepless speed change device for adhesive tape fatigue testing machine of the present invention; Fig. 2 is the transmission principle schematic diagram of shaft-type stepless speed change device for adhesive tape fatigue testing machine of the present invention.
In the present embodiment, a kind of shaft-type stepless speed change device for adhesive tape fatigue testing machine, it comprises drive motor 1 and loading motor 2, the rotating shaft of described drive motor 1 and loading motor 2 is connected to the first speed change belt wheel 4 and the second speed change belt wheel 5, test adhesive tape 3 is connected with between described first speed change belt wheel 4 and the second speed change belt wheel 5, described first speed change belt wheel 4 comprises the first fixed wheel sheet 41 be fixed on the first speed change belt wheel rotating shaft 40, coordinate the outside of the first fixed wheel sheet 41 first fixed wheel sheet 41 in the first speed change belt wheel rotating shaft 40 that first movable pulley sheet 42 is installed, installation shaft 44 is provided with in described first speed change belt wheel rotating shaft 40, one end of described installation shaft 44 is provided with spring 43, the other end is arranged on the first movable pulley sheet 42 by nut 45, by the active force of spring 43 to the first movable pulley sheet 42, described first movable pulley sheet 42 can be made to move to change the diameter of the first speed change belt wheel 4 along the first speed change belt wheel rotating shaft 40.
Described second speed change belt wheel 5 comprises the second fixed wheel sheet 51 be fixed on the second speed change belt wheel rotating shaft 50, coordinate the outside of the second fixed wheel sheet 51 second fixed wheel sheet 51 in the first speed change belt wheel rotating shaft 50 that second movable pulley sheet 52 is installed, the arranged outside of described second movable pulley sheet 52 has top to stretch oil cylinder 53, the piston rod that oil cylinder 53 is stretched on described top is connected on the second movable pulley sheet 52, and described top is stretched oil cylinder 53 and is connected oil cylinder control box 54, described top is stretched oil cylinder 53 push-and-pull second movable pulley sheet 52 and is moved to change the diameter of the second speed change belt wheel 5 along making it along the first speed change belt wheel rotating shaft 50.
Please again consult shown in Fig. 2, in the Fatigue test process of test adhesive tape 3, control top in real time by oil cylinder control box 54 and stretch the flexible of oil cylinder 53, promote the second movable pulley sheet 52 to move to close or away from the second fixed wheel sheet 51 direction, to change the gap between the second fixed wheel sheet 51 and the second movable pulley sheet 52, the change in both gaps also just changes the diameter of the second speed change belt wheel 5, when the pulley diameters of the second speed change belt wheel 5 becomes large, because the length testing adhesive tape 3 is constant, therefore the pulley diameters of the first speed change belt wheel 4 is just corresponding under the effect of spring 43 will diminish, when the pulley diameters of the second speed change belt wheel 5 diminishes, then just under the effect of spring 43, strain is large mutually for the pulley diameters of the first speed change belt wheel 4, thus realize electrodeless variable-speed.
