Abstract

The invention discloses a gear vane strength testing device and a testing method thereof. The gear vane strength testing device comprises a base, a location part, a rack and a tension meter assembly,wherein the location part is used for limiting a freedom degree for a gear to be tested to rotate in the circumferential direction; the rack is used for the gear to be tested to be meshed; in detection, the tension meter assembly can move in the tangent direction of the gear meshed position to detect strength of the gear vanes of the gear to be tested until gear vanes of the gear to be tested aredamaged. The gear vane strength testing device disclosed by the invention has the advantage of ingenious structural arrangement; the strength of the gear vanes of the gear to be tested can be measuredout by using smaller cost and simple operation; the gear vane strength testing device is favorable for a user to choose appropriate gears reasonably according to strength values of the gear vanes; furthermore, follow-up production and assembling and use safety and effectiveness of the gear in use are improved.

Description

technical field [0001] The invention relates to the field of gear tooth blade strength testing, in particular to a gear tooth blade strength testing device and a testing method thereof. Background technique [0002] At present, gears are roughly divided into plastic gears and metal gears; plastic gears have the advantages of light weight, low working noise, wear resistance, no lubrication, can be formed into more complex shapes, and low cost in mass production. However, due to the shrinkage and water absorption of plastic itself, the relative strength of metal is relatively weak, the requirements for working environment are high, and the characteristics of sensitivity to temperature; With the application of new materials and the development of manufacturing technology, the precision of plastic gears is getting higher and higher, and the service life is getting longer and longer, and they are widely used in industries such as instruments, meters, toys, automobiles, and printe...
