The number of diameter length is described!
(1) the diameter of the spring wire d: is the wire diameter of the spring.
(2) the maximum outer diameter of the spring outer diameter D: spring.
(3) the inner diameter of the spring D1: the smallest outer diameter of the spring.
(4) the middle diameter of the spring D2: the average diameter of the spring. Their formula is: D2 = (D + D) = 2 = D 1 + D = D D.
(5) apart from the support ring, the distance between the two adjacent circles of the spring corresponding to the axial distance of the point on the middle diameter is t:, and is expressed by t.
(6) the number of effective circles n: springs can keep the number of circles with the same pitch.
(7) Number of supporting coils n2: In order to make the spring work uniformly, ensure that the vertical end of the axis, manufacturing, often the two ends of the spring together. The number of tight loops only plays a supporting role, which is called the supporting ring. Generally, there are 1.5T, 2T and 2.5T, and 2T is commonly used.
(8) the total number of cycles n1: the number of effective cycles and the sum of supporting cycles. That is, the height of n1=n+n2.
(9) high H0: spring without external force. Calculated from the following: H0=nt+ (n2-0.5) d=nt+1.5d (n2=2)
(10) spring expansion length L: length of wire required for winding springs. L (N1 D2) 2+n2 (pressure spring) L=, D2 n+ hook expansion length (pull spring)
(11) spiral direction: left and right spin, commonly used dextral, the drawings do not indicate the general use of dextral.
(12) the spring winding ratio; the ratio of the diameter D to the diameter of the steel wire d 1) the diameter of the spring wire d: the diameter of the wire for making the spring. 2) the maximum outer diameter of the spring outer diameter D: spring. 3) the inner diameter of the spring D1: the smallest outer diameter of the spring. 4) the middle diameter of the spring is D2: the average diameter of the spring. Their calculation formula is: D2 = (D + D1) 2 = D1 + D = D D 5) t: except the supporting ring, and the axial distance of the two rings adjacent to the spring becomes the pitch distance on the middle diameter, and is expressed in t. 6) the number of effective circles n: springs can keep the number of circles with the same pitch. 7) Number of supporting coils n2: In order to make the spring work uniformly, ensure that the vertical end of the axis, manufacturing, often the two ends of the spring together. The number of tight loops only plays a supporting role, which is called the supporting ring. Generally, there are 1.5T, 2T and 2.5T, and 2T is commonly used. 8) the sum of the total circle number of n1: and the sum of the support circle. That is, n1=n+n2. 9) the height of free high H0: spring is not affected by external force. Calculated from the following way: H0=nt+ (n2-0.5) d=nt+1.5d (n2=2) 10) the spring expansion length L: the length of the wire required for winding the spring. L N1 (D2) 2+n2 (compression spring) L= D2 n+ hook expansion length (pull spring) 11) spiral direction: there is a right and left spin, usually dextral, the drawings are not marked in the general use of dextral. 12) spring winding ratio; the ratio of medium diameter D to steel wire diameter D.
