Abstract
A torsional fatigue testing machine relates to a testing instrument, in particular to a torsional fatigue performance index for detecting solid rubber strips under various temperature conditions. A torsion shaft is vertically arranged in a case through a bearing, the upper end of the torsion shaft extends into a high-temperature box, the upper end of the torsion shaft is connected with a lower chuck, the lower end of the torsion shaft is concentrically connected with a swinging wheel, a speed reducing motor is also arranged in the case, the output end of the speed reducing motor is connected with an eccentric wheel, and a torsion rod is hinged between the eccentric wheel and the swinging wheel; an upper chuck is vertically arranged in the high-temperature box. The sample is clamped between the upper chuck and the lower chuck, the speed reducing motor is started, and the torsion rod drives the deflection wheel to rotate around the circle center of the deflection wheel in a reciprocating manner under the action of the eccentric wheel, so that the lower chuck at the upper end of the torsion shaft is in reciprocating torsion relative to the upper chuck. The temperature in the high-temperature box can be controlled to perform torsion fatigue tests of different frequencies on the sample under different temperature conditions.
Description
Technical field
The utility model relates to a kind of test instrument, especially for detecting the distortion fatigue behaviour index of solid adhesive tape under all temps condition.
Background technology
Solid adhesive tape product in the past detects the requirement of not twisting fatigue behaviour in the index, and solid adhesive tape in use needs to stand high-frequency distortion, the requirement that product can not adapt to its working environment often occurs, and the life-span has a greatly reduced quality.
The utility model content
The utility model purpose is to design the repeated torsion test machine of the solid adhesive tape distortion of a kind of logical detection fatigue behaviour index.
The utility model comprises cabinet, high-temperature cabinet, in cabinet, vertically arrange torsion shaft by bearing, the upper end of described torsion shaft is inserted in the high-temperature cabinet, upper end at torsion shaft connects lower chuck, the lower end of torsion shaft connects a wobble wheel with one heart, in cabinet, also arrange a reducing motor, connect an eccentric wheel, between eccentric wheel and wobble wheel, be hinged a torque rod at the output terminal of reducing motor; The vertical upper grip of arranging in high-temperature cabinet.
During test, specimen holder is held between upper and lower two chucks, starts reducing motor, because eccentric effect makes torque rod drive deflecting wheel around its back and forth rotation of center of circle do, so, back and forth reverse with the relative upper grip of lower chuck of torsion shaft upper end.Can under condition of different temperatures, do the repeated torsion test of different frequency by the temperature in the control high-temperature cabinet to sample.
In order to do the test of two or more samples simultaneously, the utility model is also arranged secondary torsion shaft parallel and torsion shaft by bearing in cabinet, the upper end of described secondary torsion shaft is inserted in the high-temperature cabinet, at the upper end of secondary torsion shaft auxiliary connection lower chuck, the vertical secondary upper grip that cooperates with secondary lower chuck of arranging in high-temperature cabinet; The lower end of secondary torsion shaft connects a secondary wobble wheel with one heart, is hinged a connecting link between described secondary wobble wheel and the wobble wheel.Can be between relative secondary upper grip and secondary lower chuck the corresponding sample of clamping, to improve the work efficiency of test, also be beneficial to the contrast of test figure.
