Problems solved by technology

[0002] In the past, there was no requirement for twist fatigue performance in the testing indicators of solid rubber strip products, but solid rubber strips need to withstand high-frequency twisting during use, and often the product cannot adapt to the requirements of its working environment, and its service life is greatly reduced

Embodiment Construction

[0008] Such as figure 1 , 2 As shown, the present invention includes a cabinet 1 and a high temperature cabinet 7. In the cabinet 1, the torsion shafts 5 and 5' are vertically arranged respectively through two sets of bearings, and the upper ends of the torsion shafts 5 and 5' extend into the high temperature cabinet 7 respectively. The upper ends of the torsion shafts 5 and 5' are respectively connected with the lower chucks 6 and 6'. The lower ends of the torsion shafts 5 and 5' are concentrically connected with the swing wheels 4 and 4' respectively.

[0009] A reduction motor 2 is also arranged in the cabinet 1, an eccentric wheel 3 is connected to the output end of the reduction motor 2, and a torsion bar 12 is connected between the eccentric wheel 3 and the swing wheel 4 through a pin hinge respectively, and the swing wheel 4' is connected to the swing wheel 4'. A connecting rod 14 is also hingedly connected between the swing wheels 4 .

Abstract

The invention relates to a fatigue tester, which relates to an instrument for testing, wherein two torsion shafts are vertically arranged in a cabinet through a bearing, the upper ends of the torsion shafts are inserted in a high-temperature cabinet, the upper ends of the torsion shafts are connected with a lower chuck, and the lower ends of the torsion shafts are concentrically connected with a relative wobble wheel, a speed reduction motor is further arranged in the cabinet, the output end of the speed reduction motor is connected with an eccentric wheel, a torque rod is hinged between the eccentric wheel and either of the wobble wheels, a connecting bar is hinged between the two wobble wheels, and an upper chuck is vertically arranged in the high-temperature cabinet. Samples are clamped between the upper chuck and the lower chuck, two groups of samples are led to simultaneously do torsion fatigue tests with different frequencies under different temperature conditions through controlling temperatures in the high-temperature cabinet to improve the work efficiency of tests, and the fatigue tester is further beneficial for comparing test data.

Description

technical field [0001] The invention relates to a testing instrument, in particular for testing the torsion fatigue performance index of a solid rubber strip under various temperature conditions. Background technique [0002] In the past, there was no requirement for twist fatigue performance in the testing indicators of solid rubber strip products, but solid rubber strips need to withstand high-frequency twisting during use, and often the product cannot adapt to the requirements of its working environment, and its service life is greatly reduced. Contents of the invention [0003] The purpose of the invention is to design a torsion fatigue testing machine which can detect the torsion fatigue performance index of a solid rubber strip. [0004] The invention includes a case and a high-temperature case. Two torsion shafts are vertically arranged through bearings in the case. The upper ends of each torsion shaft extend into the high-temperature case, and the upper ends of eac...
