Intelligent portable detector for tooth strength of transmission gear

Abstract

The invention relates to the technical field of gear detection, in particular to an intelligent portable detector for the tooth strength of a transmission gear, which comprises a detection table, a pressing rod and an inductor. As the strength of a plastic gear in a mechanical component is lower than that of a metal part, and the strength condition of the plastic gear is difficult to directly observe like that of the metal gear in the maintenance process of the mechanical component, the gear needs to be sent to a professional testing device of a detection mechanism for testing the tooth strength of the plastic gear, and direct detection of a small number of gears is inconvenient. Therefore, a worm shaft is driven to rotate through a pressing rod arranged in the detection table, a motor driving mode in detection is replaced, the strength of a gear installed in a clamping cylinder is tested, the structural size of the gear detector is reduced, the applicability of the detector is improved through the clamping cylinder for adjusting the position and a worm shaft, and the use effect of the intelligent portable detector for the tooth strength of a transmission gear is improved.

Description

technical field [0001] The invention relates to the technical field of gear detection, in particular to an intelligent portable detector for transmission gear tooth strength. Background technique [0002] Gears and their transmission devices are widely used in mechanical equipment and use a large amount of basic components. The level of design and manufacture is related to the performance and quality of mechanical equipment. With the development of material technology, plastic gears have also been applied. Using plastic gears Compared with metal gears, it has better lubricity and wear resistance, and can reduce noise and cost. For example, in automotive window lifters and wipers and other components, its smaller transmission torque mechanism, and compared with Metal gears do not need to consider the conditions of rain erosion, which makes plastic gears have a unique advantage.

Problems solved by technology

[0003] At present, after long-term use of plastic gears, due to their lower strength in mechanical components compared to metal parts, plastic gears are susceptible to greater stress when in contact with metal components, and during the maintenance of mechanical components , the strength of plastic gears is difficult to observe directly like metal gears. To test the strength of plastic gear teeth, it is necessary to send the gears to the professional testing device of the testing agency, which is not convenient for direct testing of a small number of plastic gears.

[0004] In the prior art, there are also some technical solutions on the strength detection of transmission gear teeth. For example, a Chinese patent with application number CN202021032404.6 discloses a motor gear strength detection device, including: analog motor shaft, analog gear shaft; Both the simulated motor shaft and the simulated gear shaft are equipped with gears, and the adjacent gears mesh with each other; the simulated load is used to provide a load force for the gear to hinder its rotation; the torque loaded on the simulated motor shaft simulates the gear on the motor shaft The torque is transmitted to the meshing gear, and the corresponding torque value when the gear is damaged is the limit torque reflecting the gear strength; the motor gear strength detection device of this technical solution can quickly detect the broken tooth strength of the motor gear mechanism in the non-energized state, and can It is used to check the strength consistency of gear parts at the stage of purchasing and entering the factory, and can also be used to effectively analyze the broken tooth strength of gear parts with a small number of broken teeth; however, this technical solution does not effectively solve the difficult strength of plastic gears. It can be directly observed like metal gears, and professional testing of plastic gears is not convenient for direct detection of a small number of plastic gears at the mechanical component maintenance site
