Gear Rockwell Hardness Tester http://www.txhardnesstester.com Gear Rockwell hardness tester can test the surface hardness of gear, gear axel and the sprocket after heat treatment such as quenching and tempering, induction hardening, carburizing, carbon and nitrogen permeation. The gear includes spur gear with a suitable thickness, helical gear with its inner gear being cut off. Gear Rockwell hardness test is simple to operate by griping some gears. It can test surface hardness of the gear reference circle and each batching measuring time is less than 30 seconds. PHR-G6 and PHR-G28 are available now and their opening sizes can reach 140mm and 700mm, their testing modulus's range is from 2 to10 and 3 to 35. In addition, the total testing force of this instrument is small, therefore, the small indentation can be easily removed by grinding. Gear hardness tester can directly display the hardness of HRC Rockwell hardness testing device, thus it doesn't need to look up the table to converse the results, which improves the efficiency of the measurement greatly. Features of Gear Rockwell Hardness Tester 1. The gear tooth Rockwell hardness tester is a portable instrument used for directly testing Rockwell hardness of gear tooth. 2. The portable Rockwell hardness tester makes use of 120°diamond Rockwell indenter, test force of 62.5kg to measure the hardness of HRC62.5 workpieces. It displays the HRC hardness value through HRC: HRC62.5=2:1 (indentation depth ratio). 3. It works like a common normal micrometer, and serves to test the gear tooth hardness at the point of pitch circle by clamping some teeth. 4. With slight indentation, the gear tooth Rockwell hardness tester does not affect the normal use of most workpieces. Hence, it can be directly used to test finished and semi-finished parts. 5. The portable Rockwell hardness tester has a wide testing range, with the modulus between 2 and 35, and the maximum common normal length up to 1500mm, which covers a majority of industrial gears.

6. It has high testing accuracy, with an error less than 2.0HRC. 7. The gear tooth Rockwell hardness tester is easy and convenient to operate, just by giving a few pokes to the force applying rod, with the average total testing time within 10 seconds. 8. Based on practicable Rockwell hardness testing method, the gear tooth Rockwell hardness tester achieves real, reliable and accurate testing. 9. It is generally employed for hardness testing of gear internal tooth, external tooth, straight tooth, helical tooth, and more. 10. The intelligent digital gear tooth hardness tester is under development. Technical Parameters of Gear Rockwell Hardness Tester Initial test force
