Abstract
The utility model relates to a face-gear bowl-type gear shaping cutter. Gear shaping cutters are divided into disc-type cutters, bowl-type cutters, cylindrical cutters and taper shank cutters according to profile, but the gear shaping cutters for machining face gears are not many. The face-gear bowl-type gear shaping cutter comprises a cutter body, wherein the cutter body comprises an inner hole (1) and a tooth portion (3), the inner hole (1) is provided with three stairs, the tooth portion (3) is arranged on the outer side of the cutter body, cutting teeth (4) are arranged on the tooth portion (3), each cutting tooth (4) comprises a cutter tooth lateral face (5), a cutter tooth front edge face (6) and a cutter tooth top face (7), and key grooves or spline grooves (2) are formed in the inner hole. The face-gear bowl-type gear shaping cutter is used for machining the face gears, and is simple in structure and high in efficiency.
Description
Technical field:
The utility model relates to field of machining, is specifically related to a kind of gear bowl type gear shaping cutter.
Background technology:
The face gear drive is a kind of new mechanical dynamic structure.Gearratio is big, compact conformation, thereby have bigger development prospect in fields such as space flight.Be different from the spur gear of common reference circle and gear centre line parallel, reference circle becomes the helical gear of 45 degree with the gear centre line, and the reference circle of face gear is the plane vertical with the gear centre line.
In the conventional gear mechanism processing, comprise the multiple mode of gear shaping, gear hobbing, shaving, roll flute etc.Wherein pinion cutter is divided into 4 kinds of dish type, bowl-type, tubular and taper shanks by profile.Disk slotting cutter is mainly used in processing straight-tooth, pinion cutter helical teeth and the herringbone bear of inside and outside engagement.The bowl-shape gear shaping tool spur gear with multi-joint inside and outside engagement main processing belt shoulder, the difference of it and disk slotting cutter clamp usefulness when being work nut can be contained in the cutter hub of pinion cutter, thereby does not hinder processing.The tubular pinion cutter is used for machining interal and the little external gear pump of modulus, and the screw thread in inner hole is tightened on the main shaft of gear shapping machine.Straight-tooth and the angular gear of engagement in tapered shank cutter is mainly used in processing.But be fit to face gear structure characteristic, the pinion cutter that is specifically designed to the face Gear Processing is also few.
Summary of the invention:
The purpose of this utility model is to carry a kind of gear bowl type gear shaping cutter, can the opposite Gear Processing, and simple in structure, the efficient height.
The purpose of this utility model is achieved in that
A kind of gear bowl type gear shaping cutter, its composition comprises: cutter body, described cutter body comprises endoporus with 3 layers of ladder and the tooth portion in the outside, has cutting teeth in the described tooth portion, each cutting teeth comprises cutter tooth side, cutter tooth lip surface and cutter tooth end face, has keyway or spline in the described endoporus.
Described gear bowl type gear shaping cutter has keyway or spline in the described endoporus, the sword mask of described cutting teeth has hard alloy coating, and the number of teeth of described cutting teeth is 3-16, along circumferentially uniform.
Beneficial effect:
1. the utility model cutting edge surface has hard alloy coating, machining accuracy height, long service life.
The described cutter body of utility model comprises having endoporus, and end and tooth portion are simple in structure.
Have cutting teeth on the tooth end surface described in the utility model, each cutting teeth comprises cutter tooth side, cutter tooth lip surface and cutter tooth end face, and the number of teeth of described cutting teeth is 3-16, can raise the efficiency during Gear Processing.
By key or the accurate orientation angle of spline, guarantee the transposition precision in the face Gear Processing in the endoporus.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is shape schematic diagrames of the utility model cutting teeth.
The specific embodiment:
Embodiment 1:
A kind of gear bowl type gear shaping cutter, its composition comprises: cutter body, described cutter body comprises endoporus 1 with 3 layers of ladder and the tooth portion 3 in the outside, has cutting teeth 4 in the described tooth portion, each cutting teeth comprises cutter tooth side 5, cutter tooth lip surface 6 and cutter tooth end face 7, has keyway or spline 2 in the described endoporus.
Embodiment 2:
Described gear bowl type gear shaping cutter has keyway or spline in the described endoporus, the sword mask of described cutting teeth has hard alloy coating, and the number of teeth of described cutting teeth is 3-16, along circumferentially uniform.
Claims (2)
1. face gear bowl type gear shaping cutter, its composition comprises: cutter body, it is characterized in that: described cutter body comprises endoporus with 3 layers of ladder and the tooth portion in the outside, has cutting teeth in the described tooth portion, and each cutting teeth comprises cutter tooth side, cutter tooth lip surface and cutter tooth end face.
2. according to claim 1 gear bowl type gear shaping cutter, it is characterized in that: have keyway in the described endoporus, the sword mask of described cutting teeth has hard alloy coating
, the number of teeth of described cutting teeth is 3-16, along circumferentially uniform
3.According to claim 2 gear bowl type gear shaping cutter, it is characterized in that: described keyway is spline.
