Abstract
The utility model relates to a gear hob; and inclined angles of two main cutting edges on the sides of the gear hob are 28 degrees. The utility model has the advantages of strong carrying capacity during the spline processing operation of the gear hob with a 30 degrees pressure angle, and low gear noise and vibration during the spline processing operation of the gear hob with a 25 degrees pressure angle.
Description
Technical field
The utility model relates to a kind of gear hob, especially a kind of special gear hobboing cutter of 28 degree pressure angles.
Background technology
In the rubber and plastics machine industry, the main transmission device of rubber internal mixer is a reductor, the output of main gear reducer is gone into a shaft coupling external tooth axle sleeve and was external splines in the past, though external splines has the strong advantage of bearing capacity, but inside and outside spline fitted type is a matched in clearance, and rigid attachment causes vibrating noise bigger.In addition, splined requires high to assembly precision, and deformability is poor, and the shaft coupling contact precision is difficult to guarantee.Adopt 30 traditional degree pressure angle gear hob processing splines, the gear noise vibration is bigger, adopts 25 traditional degree pressure angle gear hob processing splines, and bearing capacity will descend.
Summary of the invention
The purpose of this utility model is: at adopting 30 traditional degree pressure angle gear hob processing splines, the gear noise vibration is bigger, adopt traditional 25 degree pressure angle gear hobs processing splines to hold, the practical problem that loading capability will descend provides the gear hob at a kind of particular pressure angle.
The purpose of this utility model is achieved in that a kind of gear hob, it is characterized in that: the angle of inclination of two main cutting edges of side is 28 degree.
In the utility model: gear hob is the inserted-blade type gear hob, or the integral gear hobboing cutter.
Advantage of the present utility model is, it is strong and adopt the low advantage of spline work middle gear noise vibration of the gear hobs processing of 25 degree pressure angles to have inherited bearing capacity in the spline work of the gear hobs processing of adopting 30 degree pressure angles.
Description of drawings:
Fig. 1 is the gear hob normal tooth profile figure that the utility model relates to.
The specific embodiment
Accompanying drawing discloses the concrete structure of the utility model embodiment without limitation, below in conjunction with accompanying drawing the utility model is further described.
As seen from Figure 1, the angle of inclination of two main cutting edges of side of gear hob normal tooth profile is 28 degree, and present embodiment is the integral gear hobboing cutter.
The utility model in the specific implementation, gear hob also can be the inserted-blade type gear hob, after the gear hob body is to tumble in roll blade, the angle of inclination of two main cutting edges of side be 28 the degree.
Claims (2)
1, a kind of gear hob is characterized in that: the angle of inclination of two main cutting edges of side is 28 degree.
2, gear hob according to claim 1 is characterized in that: gear hob is the inserted-blade type gear hob, or the integral gear hobboing cutter.
