Hydraulic fluid power - Mounting dimensions for accessories of single rod cylinder - Part 2.16 MPa compact series with bores from 25 mm to 220 mm ICS 23.100.20 J20 National Standards of People's Republic of China Installation dimensions of hydraulic transmission single rod cylinder accessories Part 2.16MPa cylinder diameter 25mm~220mm Compact series [ISO 8133.2014,Hydraulicfluidpower-Mountingdimensionsfor Released on 2021-03-09 2021-10-01 implementation State Administration of Market Supervision and Administration Issued by the National Standardization Management Committee ForewordGB/T 39949 "Installation Dimensions of Hydraulic Drive Single Rod Cylinder Accessories" is divided into 3 parts. ---Part 1.16 MPa medium series and 25 MPa series; ---Part 2.16 MPa Bore 25 mm~220 mm compact series; ---Part 3.16 MPa Bore 250 mm~500 mm compact series. This part is GB/T Part 2 of 39949. This part is in accordance with GB/T 1.1-2009 The rules given are drafted. This section uses the redrafting method to modify and adopt ISO 8133.2014 ``Hydraulic Transmission 16 MPa(160 bar) Compact series single rod cylinder Installation dimensions of ". This part and ISO Compared with 8133.2014, there is a structural difference, and the attachment type of Chapter 6 is added. This part and ISO The technical differences of 8133.2014 and their reasons are as follows. ---Regarding normative reference documents, this section has made adjustments with technical differences to adapt to my country's technical conditions and adjustments. The situation is collectively reflected in Chapter 2 "Normative Reference Documents", and the specific adjustments are as follows. ● Use non-equivalent GB/T that adopts international standards 1184 instead of ISO 2768-2 (see 5.3); ● Adopt GB/T of international standard with modification 1800.2 instead of ISO 286-2 (see 7.1.1); ● Use non-equivalent GB/T that adopts international standards 1804 instead of ISO 2768-1 (see 5.2); ● Use GB/T equivalent to adopting international standards 9094 instead of ISO 6099 (see Chapter 6); ● Use GB/T equivalent to adopting international standards 17446 instead of ISO 5598 (see Chapter 3). --- "Single earring bracket" in accessory type AB2 is modified to "single earring bracket, symmetrical type" (see Chapter 6, Figure 7, Table 7, Example 7, ISO Chapter 1 of 8133.2014, Figure 7, Table 7, Example 7). ---Accessory type AB4 "Double earring bracket, symmetrical type" is modified to "double earring bracket, through hole, symmetrical type" (see Chapter 6, Figure 8, Table 8.Example 8, ISO Chapter 1 of 8133.2014, Figure 8, Table 8, Example 8). ---The drawing of the accessory type AL6 is modified to include the structure diagram of the lock plate, pin shaft, double earrings and screws (see Figure 4, ISO 8133. Figure 4 in.2014). --- Increase the user's use requirements in the swing angle. "(When the user uses it, the swing angle should not exceed ±3°) (see 7.1.2)".
