The tooth flanks of the bevel gear can be thought of as being enveloped by a shaped rack. The plane of symmetry of the shaped rack is inclined at an angle D to the axis of the bevel gear. The conical surface of the bevel gear that is tangent to the plane of symmetry of the shaped rack is called the reference conical surface of the gear, and the angle D is called a gear. The taper angle of the reference cone is simply referred to as the reference cone angle, and the tip cone angle and the root cone angle are generally equal to D.
The intersection of the tooth surface of the production rack and the symmetry plane is called the tooth line of the prosthetic rack of the Boshan water pump manufacturer, and the angle Bc between the vertical line of the moving direction of the production rack is called the production rack. The angle of inclination of the tooth; in the section perpendicular to the tooth line, the section line of the tooth surface of the shaped rack is the normal tooth shape of the shaped rack, and the angle Anc between the line and the normal line of the symmetry plane is called the method To the tooth angle, the modulus mnc of the shaped rack in this section is called the normal modulus.
The above parameters are the basic parameters of the production rack, and they are the main parameters of the design and processing of the bevel gear.
When the production rack and the bevel gear are purely rolled, the tooth surface of the shaped rack determines the tooth surface of the bevel gear. The helix angle and the end face tooth angle of the left and right tooth flanks of the conical gear joint cylinder: tanB=tanBc*cosDosinD*tanAnccosBc, tanA=tanAnc*cosDcosBcsinD*tanBc. The above two types are suitable for right-handed gears, and for left-handed gears, Bc should be substituted with negative values.
When Bc=0, it is called a spur bevel gear. It can be seen that the B of the left and right tooth faces of the spur bevel gear is not zero, and they are equal in size and opposite in direction.
