●This link is for 45 degree helical/helical gears, which can be used parallel (180 degrees) or staggered (90 degrees) in general machinery.
●The larger the module, the larger the tooth shape, and the larger the load carrying capacity. As long as the module is the same, the number of teeth can be paired to form different transmission ratios.
●Reduces the load of each pair of gears, improves the load carrying capacity of gears; reduces the noise problem.
●Gear material is 45# steel, high-frequency quenching and hardening, blackened surface, with 90 degree threaded holes in the cam, the inner hole can be directly mounted and used.
●There are three kinds of bore (through hole + threaded hole), (keyway hole + threaded hole) (D hole + threaded hole), the option is not marked keyway or D hole size is (through hole + threaded hole).
●If you buy a helical gear (with fixing screws), you need to buy the key pin for the keyway separately.
●Keyway holes are made by broaching process, the error value of width is 0.05, the error value of depth is 0.02 range. Specific according to the physical shall prevail.

01, left-hand and right-hand rotation of any two different directions of rotation of the number of teeth, can be paired with 90-degree installation.
02, high-quality 45-gauge steel products from high-quality materials, sturdy and good service life.
03, high-frequency quenching strength and hardness increase, wear-resistant fatigue strength and toughness of the inner hole H7 tolerance.
04, high efficiency energy-saving gear motor efficiency of up to 95% or more vibration low noise, high strength and good mechanical properties.
