The largest dimensi
18、on of the inside diameter of the bush in its pressed-in condition is obtained from the largest dimension of the bore in the housing minus twice the smallest dimension of the wall thickness, s3. The smallest dimension of the inside diameter of the bush in its pressed-in condition can be obtained from
19、 the smallest dimension of the bore in the housing minus twice the greatest dimension of the wall thickness, s3. This assumes that there is no expansion of the bore in the housing caused by pressing in the bush. In reality, the expansion depends on several factors, such as the stiffness of the housi
20、ng and the bush. An example of the calculation is given in Clause 7. The wall thickness limit deviation depends on whether or not there is a machining allowance in the bush bore and on the material type, as specified in ISO 3547-4. The preferred limit deviation series (A to E) is specified in Table
21、5. Instead of the wall thickness, the inside diameter, Di, ch, of the bush may be specified. Di, chis the inside diameter of the bush, when this is pressed into a ring gauge (Test C gauging in accordance with ISO 3547-2:2006, see also ISO 3547-6). 6 DIN ISO 3547-1:2015-12 For bushes which are suppli
22、ed with a machined bore (Series W), the limit deviations of the inside diameter of the bush, Di, ch, checked in a ring gauge, are given in Table 6. In no case shall wall thickness and inside diameter be given at the same time as the dimensions that are to be checked. The tolerance for the inside dia
23、meter, Di, ch, of the bush in the ring gauge is given in Table 6. The tolerance of the inside diameter of a bush pressed into a housing is found from the sum of the tolerance for, Di, ch, and the tolerance of the housing bore. As in the case of the calculation of the inside diameter from the wall th
24、ickness, it is assumed that there is no expansion of the housing bore. Dimensions for the outside diameter, Do, of the bush are given in Table 7. 7DIN ISO 3547-1:2015-12 Dimensions in millimetres Type C cylindrical bush Type F flanged bush Key 1 split aThickness of the bearing material layer: only v

After it has been pressed into its housing, in general, a wrapped bush is round and its split is
43、 closed. Wrapped bushes can be closed by an interlocked split. The design of the split is left at the discretion of the manufacturer. Wrapped bushes are supplied with or without a machining allowance in the bore. Bushes supplied with a machining allowance are finish-machined to the desired dimension
44、s by the customer after they have been pressed into their housings. Such bushes cannot be supplied in all materials. Wrapped bushes which comply with this part of ISO 3547 are supplied in the limit deviations series A to E, as specified in Table 5, and Series W, as specified in Table 6. Lubrication
45、holes, lubrication grooves or lubrication indents should preferably be designed such that they can be stamped or punched. Distortion caused by the wrapping operation is permissible. All edges and corners shall be free from loose burrs. Burrs which do not affect installation or function are permissib
46、le. ISO 3547-2:2006, Test B, does not stipulate any figure for outside diameter, Do. In order to obtain a sufficiently tight fit of the bush in the housing bore when using test B, experimentally determined gauge inside diameters are used. These depend on the method of manufacture and cannot therefor
47、e apply in every single case. Specification of a maximum and minimum pressing in force increases the safety of this test method. The details of test should be agreed for each individual case.
