Detailed Product Description: | Threaded connection (Threaded connection) is a detachable fixed connection, has a simple structure, reliable connection, easy assembly and disassembly, etc., are widely used in mechanical engineering, structural connection areas. To distinguish between the different threads, it is necessary to grasp the characteristics of the threads of some parameters. A cylinder common thread widely used, for example, the main parameters of the thread is as follows: (1) large diameter d (outside diameter) (D) - with the external thread crests coincide with the imaginary cylindrical surface diameter - also known as the nominal diameter ( 2) small diameter (inner diameter) d1 (D1) - with the external thread root coincide with the diameter of an imaginary cylindrical surface, the diameter as calculated in the risk of cross-sectional strength calculation (3) diameter d2-- tooth thickness in axial cross-section imaginary cylindrical surface with a diameter equal to the width at the dental, approximately equal to the average diameter d2≈0.5 threaded (d + d1) (4) P-- pitch corresponding to two adjacent teeth in the cylindrical surface of the medium diameter bus between two points axial distance (5) lead (S) - the same helix in the axial distance between two adjacent teeth on the cylindrical surface of the medium diameter corresponding bus between two points (6) lines n-- thread helix The number, usually in order to facilitate the manufacture n≤4; the relationship between pitch, lead, line number: L = nP (7) helix angle ψ-- in tangent with the vertical diameter of the cylindrical surface of the helix to helix axis the angle between the plane. The angle between the two sides of the thread profile within the tooth type angle α-- threaded axial plane (8); tooth type bevel angle β means the vertical plane of the side and thread type screw axis. Symmetrical tooth type. |
