The name of laser pointer is 100mW bright laser pointer pen

The name of laser pointer is 100mW bright laser pointer pen.
The gear is the most widely used mechanical equipment drive system extremely large number of general machinery parts, easy to produce in the course of fatigue pitting, glue, broken teeth, the failure phenomenon. Gear surface quality of a direct impact on the quality and longevity of the transmission components, so in order to effectively improve the carrying capacity of gear, extending its life, usually in the enhanced treatment methods to improve the surface of the gear tooth surface hardness. Gear laser surface hardening is the drawback of a new type of gear surface enhancement technology, it can overcome the traditional gear surface strengthening process, such as carburizing, induction hardening, the hardened layer of uneven distribution of large deformation, the leading edge of the gear cutting The technology has been used gear handle on the U.S. nuclear submarine; is a very promising high-tech. The green laser pointer is one of the most commonly used laser pointer in the practical use.The customer only needs to press the button on laser pointer
As early as 1980, the U.S. military Applied Technology Laboratory for laser hardening of gears findings had a radio program reported borne by Chicago, Illinois Institute of Technology Institute of the research projects of laser hardening of gears, then published the experimental results: laser surface hardening, laser hardening to replace the the AMS6265 gear carburizing treatment in the aviation devices and spur gears by carburizing AMS (American Airlines Material Specification) 6265 anti-glue life and tooth bending strength significant economic effects, the effective hardening depth of 0.66 ~ 0.86mm. Of course, different output powers of laser pointer can be customized.
Reduce the unit cost by 37% to 78%. The late 1980s, the United States, California Institute of Electrical 5kW laser laser hardening of large spline shaft to obtain the quenching hardness HRC59 depth of 0.762 to 0.864mm of the hardened layer. U.S. military Institute of laser quenching submarines, aircraft, overloaded gear, to solve the conventional heat treatment caused the gear deformation is too large and noise problems. laser hardening of gears including a drive gear of the planetary gear of the AH-64 helicopter auxiliary power units and aircraft main gear. the laser does not require grinding after hardening, it can greatly reduce production costs and increase productivity. At present, the study of domestic gear laser quenching of the laser scanning method, mechanism and process parameters optimization techniques to obtain certain results.
