Abstract
The invention relates to a double contact gear hobbing cutter. The main points include that the addendum circle radius of the gear hobbing cutter is 0 to 0.3 time of modulus; a standard pressure angle with an angle degree of 15-30 degrees is arranged on a gear surface of 0.3 to 0.8 time of gear height below the addendum; an interference amount cutting pressure angle with an angle degree of 22-37 degrees is arranged on a gear surface of 0.05 to 0.6 time of the gear height below the standard pressure angle; and an addendum chamfering pressure angle with an angle degree of 25-50 degrees is arranged on a gear surface of 0.05 to 0.3 time of the gear height below the interference amount cutting pressure angle. The double contact gear hobbing cutter has the advantages of being simple in structure, easy to manufacture, low in cost, convenient and rapid to mount and dismount, used for processing double contact gears, simple in process, low in processing time and capable of guaranteeing the smooth connection between gradual opening line portions and transition curve portions, improving processing accuracy of the double contact gears and processing efficiency and reducing processing cost.
Description
Technical field
The present invention relates to a kind of hobcutter of Machining of Gear, be 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 has obtained extensive use 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 the flank of tooth contact fatigue strength and the flexural strength of the roller gear of this pure involute flank are little, and noise is big when engagement, flank of tooth easy abrasion, and service life is short.Noise was little when two Contact Tooth wheels that gear teeth face is made up 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 objective of the invention is to overcome the shortcoming of above-mentioned technology, provide a kind of easy to manufacture, 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 invention 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, and the flank of tooth and gear hobbing slotted line form 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.
Of the present invention pair the contact roller serrated knife is simple in structure, easy to manufacture, expense is low, and cutter is easy to loading and unloading fast, and is time saving and energy saving; Be used to process two contact gears, can accurately the required amount of interference and the amount of uprooting of wiping out be provided, guaranteed smooth connection of involute part and easement curve part for gear fine finishining; 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.
