How to describe the size of the shaft retaining ring
Method:
(1) Spring wire diameter d: The diameter of the steel wire used to manufacture the spring.
(2) Spring outer diameter D: The maximum outer diameter of the spring.
(3) Spring inner diameter D1: The minimum outer diameter of the spring.
(4) Spring medium diameter D2: The average diameter of the spring. Their calculation formula is: D2 = (D + D1) ÷ 2 = D1 + d = D - d
(5) t: Except for the support ring, the axial distance between the corresponding points on the two adjacent rings of the spring at the medium diameter is the pitch, represented by t.
(6) Effective number of turns n: The number of turns that the spring can maintain at the same pitch.
(7) Number of support rings n2: In order to ensure uniform stress on the spring during operation and ensure that the axis is perpendicular to the end face, the two ends of the spring are often tightly connected during manufacturing. The number of tightly connected rings only plays a supporting role and is called a support ring. Generally, there are 1.5T, 2T, and 2.5T, with 2T being the most commonly used.
(8) Total number of turns n1: the sum of the effective number of turns and the support number of turns. That is, n1=n+n2.
(9) Free height H0: The height of the spring without external force. It is calculated by the following formula: H0=nt+(n2-0.5)d=nt+1.5d (when n2=2)
(10) Spring deployment length L: The length of steel wire required when winding the spring. L≈n1(ЛD2)2+n2(spring compression) L=ЛD2n+hook deployment length (spring tension)
(11) Spiral direction: There are left-handed and right-handed variants, with the right-handed variant being the most commonly used. If the drawing does not specify, the right-handed variant is generally used.
(12) Spring winding ratio; ratio of the medium diameter D to the wire diameter d
1.Spring wire diameter d: The diameter of the steel wire used to manufacture the spring.
2.Spring outer diameter D: The maximum outer diameter of the spring.
3.Spring inner diameter D1: The minimum outer diameter of the spring.
4.Spring medium diameter D2: The average diameter of the spring. Their calculation formula is: D2 = (D + D1) ÷ 2 = D1 + d = D - d
5.t: Except for the support ring, the axial distance between the corresponding points on the two adjacent rings of the spring at the medium diameter is the pitch, represented by t. 6) Effective number of rings n: The number of rings that the spring can maintain at the same pitch.
6.Number of support rings n2: In order to ensure uniform stress on the spring during operation and ensure that the axis is perpendicular to the end face, the two ends of the spring are often tightened during manufacturing. The number of tightened rings only plays a supporting role and is called a support ring. Generally, there are 1.5T, 2T, and 2.5T, with 2T being the most commonly used.
7.Total number of turns n1: the sum of the effective number of turns and the support number of turns. That is, n1=n+n2.
8.Free height H0: The height of the spring without external force. It is calculated by the following formula: H0=nt+(n2-0.5)d=nt+1.5d (when n2=2)
9.Spring deployment length L: The length of steel wire required when winding the spring. L≈n1(ЛD2)2+n2(pressure spring) L=ЛD2n+hook deployment length (tension spring)
10.Spiral direction: There are left-handed and right-handed variants, with the right-handed variant being the most commonly used. If the drawing does not specify, the right-handed variant is generally used.
11.Spring winding ratio; the ratio of the pitch diameter D to the wire diameter d.
