4 grades of dish original structures of R0110 heavy combustion engine gas compressor are 4 grades of dishes and axle journal welded structure welded together, and its difficulty of processing is very big, can't guarantee designing requirement.Former 4 grades of dish structures are 4 grades of dishes and axle journal welded structure welded together, carry out the tongue-and-groove broaching of 4 grades of dishes earlier, carry out the welding of 4 grades of dishes and axle journal then, the cover tooth on the reprocessing axle journal.The processing of 4 grades of dishes is carried out at Shen Chong, and Shen Chong has investigated domestic a lot of cover tooth processing producer, gear hobbing can reach the 6-7 level, and the precision of mill teeth can only reach 10 grades.Cover tooth drawing precision prescribed on the axle journal is 5 grades, and this cover tooth transmits the output power of the 110MW ~ 120MW of R0110 heavy combustion engine, and cover tooth requirement on machining accuracy is higher.Postwelding is big because of accessory size, domestic can't gear hobbing, can only mill teeth, and the precision of mill teeth is unacceptable.So just can only before 4 grades of dishes and axle journal are welded together, carry out the cover tooth processing on the axle journal, and welding expert thinks that overlapping tooth as processing earlier welds again, the amount of deformation of welding is uncontrollable, and the form and position tolerance of postwelding can't guarantee, the possibility that exists 4 grades of dishes and axle journal to scrap.If the cover tooth on the processing axle journal welds then earlier, carry out the tongue-and-groove broaching of 4 grades of dishes again, technology department thinks that accessory size is too big, domestic processing conditions can't kerve.In a word, can't carry out under the processing processing conditions at home of 4 grades of dishes of original structure, can only improve the structure of 4 grades of dishes.
The model utility content
The purpose of this utility model is: for solving the control problem of welding deformation amount, guarantee the form and position tolerance of postwelding, and the possibility of avoiding 4 grades of dishes and axle journal therefore to scrap, the spy provides a kind of R110 heavy combustion engine gas compressor 4 grades of axle journal dishes.
The utility model provides a kind of R110 heavy combustion engine gas compressor 4 grades of axle journal dishes, described 4 grades of axle journals (1) adopt the solid forging moulding, an end that does not have the hole of its big end and linkage section (2) adopts and to be welded to connect, and adopts bolt (4) to be connected between an end that has the hole of linkage section (2) and the level Four dish (3).
Described linkage section (2) adopts the solid forging moulding, be connected with level Four dish (3) on it-hold to be evenly equipped with 55 circular holes.
Described level Four dish (3) has 55 to be used for bolted circular hole on it, has radially to adopt the entity part that increases counterweight as shown in Figure 4 to position, the center of circle, is useful on the pin connection set that is connected with 5 grades of dishes.
Described bolt (4) diameter that is used for being connected between linkage section (2) and the level Four dish (3) is 23 millimeters.
Described in the utility model, 4 grades of axle journal dishes of a kind of R110 heavy combustion engine gas compressor are that axle journal and linkage section are welded, and linkage section is connected with the bolt of 4 grades of dishes with 55 Ф 23mm, and the connection of gas compressor 4-5 level dish also adopts pin to connect.Weld together after axle journal and the linkage section roughing, reprocessing is overlapped tooth, is finished whole fine finishing, links together with bolt with 4 grades of dishes that process again.The situation that existing processing conditions can be processed is, the processing of cover tooth can reach the 6-7 level, and the required precision of cover tooth is 6 class precisions, can meet design requirement.4 grades of axle journal dishes of described a kind of R110 heavy combustion engine gas compressor have solved the problem of the uncontrollable welding deformation of original structure fully, have guaranteed the form and position tolerance on cover tooth and Bearing Installation surface, have guaranteed cover tooth machining accuracy.
Advantage of the present utility model:
4 grades of dishes of R0110 heavy combustion engine gas compressor are that 4 grades of dishes are connected with linkage section by bolt, and linkage section is connected with axle journal by welding.Its easy processing, precision are easy to guarantee that welding stress can not impact the form and position tolerance of tongue-and-groove.
