Description
Technical field
The utility model relates to a kind of hobcutter of machining gears, is specifically related to a kind of two contact roller serrated knives of two contact roller gears.
Background technology
It is simple in structure for the roller gear of involute flank, handling ease is widely applied in machine driving, and hobcutter is processed this gear, and process time, short expense was low, and hobcutter processing has generally been adopted in roller gear processing.But flank of tooth contact fatigue strength and the flexural strength of the roller gear of this pure involute flank are little, and noise is large when engagement, and the flank of tooth weares and teares easily, and service life is short.Noise was little when two Contact Tooth wheels that gear teeth face is made of involute and easement curve had engagement, had improved the strength of gear teeth and service life.Existing hobcutter is used for processing this two contact gear, complex procedures, and qualification rate is low, and processing charges is high.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of easy to manufacture, and intensity is good, and the flank of tooth is not easy to wear, long service life, the simple two contact roller serrated knives of manufacturing procedure.
Of the present utility model pair of contact roller serrated knife is characterized in that: the radius of addendum of described hobcutter is 0～0.3 times of modulus; The gear hobbing slotted line is vertical with nodel line, the flank of tooth and gear hobbing slotted line mineralization pressure angle; Described pressure angle is followed successively by the normal pressure angle, wipes out the amount of interference pressure angle, tooth top chamfered edge pressure angle; Described normal pressure angle angle is 15 °～30 °, is located on the flank of tooth of downward 0.3～0.8 times of tooth depth of tooth top; From the flank of tooth of downward 0.05～0.6 times of tooth depth of the angle point at normal pressure angle be provided with angle be 22 °～37 ° wipe out the amount of interference pressure angle; Being provided with angle from the flank of tooth of downward 0.05～0.3 times of tooth depth of the angle point of wiping out the amount of interference pressure angle is 25 °～50 ° tooth top chamfered edge pressure angle α 3.
Of the present utility model pair the contact roller serrated knife is simple in structure, easy to manufacture, expense is low, the cutter loading-unloading fast and easy, time saving and energy saving, be used for the two contact of processing gears, can accurately provide required amount of interference and the amount of uprooting of wiping out for gear fine finishining, guaranteed being smoothly connected of involute part and easement curve part, improved the machining accuracy of two contact gears, manufacturing procedure is simple, and process time is short, reduce the processing charges of two contact gears, improved working (machining) efficiency.
