Rubber material tension-torsional fatigue combined testing machine

Abstract

The invention discloses a rubber material fatigue performance detection device, and specifically discloses a rubber material tension-torsional fatigue combined testing machine. The rubber material tension-torsional fatigue combined testing machine comprises an installing support; a stretch motor, a torsion motor, lifting guide rails, and a stretch screw rod are arranged in the installing support; each lifting guide rail is provided with a lifting slide seat; a driving cross beam is arranged between the lifting slide seats; an upper clamping head is arranged on the driving cross beam; the stretch screw rod is connected with the stretch motor and the driving cross beam; a transmission shaft is arranged on the lower part of the installing support; a lower clamping head is arranged on the upper end of the transmission shaft; a torsion driving gear is arranged on the lower side of the transmission shaft; a driving gear rack engaging with the torsion driving gear is arranged on the side part of the torsion driving gear; the torsion motor is provided with a crank rotary table; the crank rotary table is connected with one end of a connecting rod via hinge joint; the connecting rod is connected a reciprocating connection block connected with the driving gear rack with via hinge joint; and a tension-torsion compound strength sensor is arranged between the upper clamping head and the driving cross beam. The rubber material tension-torsional fatigue combined testing machine is simple in structure, is convenient to use, and can be used for real simulation of working environment and working mode of rubber parts; and measured data is accurate, and can be used for real reflecting of part practical performance.

Description

technical field [0001] The invention relates to a device for detecting the fatigue performance of rubber materials, in detail, it is a comprehensive testing machine for tensile and torsion fatigue of rubber materials with simple structure and functions. Background technique [0002] We know that rubber is one of the widely used polymer materials. With the development of industrial economy, the performance requirements of rubber materials are getting higher and higher. Fatigue performance is the basis for studying the life of rubber products. At present, the fatigue testing machines in the rubber industry are all single-function tensile fatigue testing machines or torsional fatigue testing machines, which can only test the tensile fatigue characteristics or torsional fatigue characteristics of rubber parts alone. In the machinery industry such as transportation, the stress of rubber parts is varied, such as: first stretching and then twisting, first twisting and then stretch...
