KG worm gear W2S R2-M-B

[Features]
●Because it is processed by cold rolling, the surface of the screw surface is hardened by work hardening, and the metal fiber structure is not cut, so the mechanical properties are superior to machine-cut worms.
●The surface hardness after rolling is 1.2 to 1.3 times the hardness of the base material, and the hardness of the threaded surface is HB240 to 260.
●Rolled worms have a mirror-like threaded surface, so if they are used in combination with a worm wheel, the life of the worm gear will be longer than with a machined worm.

[Use]
●Used for general industrial machinery, medical equipment, food machinery, etc.

【Note】
● In order to obtain the ideal meshing, when assembling the worm and worm wheel, make sure that they are square.
●Since the friction between the worm and the worm wheel is large, please operate the worm in lubricating oil as much as possible.
●Use the worm and worm wheel with the same twist direction and the same number of threads.
●For the worm shaft and worm wheel shaft, please design the bearings as close to the gears as possible to prevent bending.
●Please note that the axial thrust acting on the worm is considerably large. For axial thrust, please refer to KG Gear Information in the General Catalog.
