Abstract

The invention discloses a comprehensive experiment platform for gear transmission strength design, which comprises a motor, a gearbox, a load and a computer processing module; the motor is connected with the load by the input shaft of the gearbox and the output shaft of the gearbox; a torque sensor is arranged on the transmission line between the motor and the gearbox, a gear to be tested in the gearbox is provided with gear strength test strain gauges, a to-be-tested gear output shaft on which the gear to be tested is mounted is connected with an angular displacement sensor, and the torque sensor, the gear strength test strain gauges and the angular displacement sensor are electrically connected with the computer processing module. By reasonably arranging the bending stress test strain gauge and the contact stress test strain gauge, the comprehensive experiment platform for gear transmission strength design can accurately measure out the contact stress and bending stress of the gear; because an attenuation-less rotary union is adopted as a signal output device, the contact stress signal and the bending stress signal can be more really, stably and reliably transmitted; and the replaceable gearbox ensures that the experimental teaching effect is more remarkable.

Description

technical field [0001] The invention belongs to a mechanical teaching experiment device, in particular to a gear transmission strength design comprehensive test bench. Background technique [0002] "Gear Transmission Design" is one of the most important chapters in the basic courses of mechanics "Mechanical Design" and "Basics of Mechanical Design". There are also many experimental devices designed for gear transmission, such as measuring the speed, torque, mechanical efficiency, and failure mode of gear transmission. In the design of gear transmission, the transmission strength is the most important factor, that is, the contact stress of the transmission gear and bending stress. According to the calculation formula of gear strength in "Mechanical Design", the contact strength of standard spur gear is ; The bending strength is ; The contact strength of standard helical cylindrical gear is ; The bending strength is . Since the existing technology is not yet able to ...
