Described bearing dismounting device, described working head connects or comprises the trussed shore part.
Connect by bearing pin when described bearing dismounting device, described working head connect described trussed shore part, and in described trussed shore part the bolt hole that is connected with described axletree is set, the slotted hole that passes through when having bearing pin to move on the described gland.
Described bearing dismounting device, described arm-tie are provided with four axis holes; Described pull bar amounts to four, and an end is connected with four axis holes of described arm-tie, and the other end is connected with four axis holes of described mobile hydraulic dolly.
Beneficial effect:
1. this product is to have satisfied the railway goods train bogie bearing to dismantle at any time and press-fit needs, and this bearing dismounting device has adopted the high strength steel making widely, uses light and intensity is high.
2. simple in structure, easy to install, input and maintenance cost are low.
2. the mobile hydraulic dolly that this bearing dismounting device and railway systems are general is used, and is flexible, by the work of hydraulic trolley oil cylinder piston bar, can realize the dismounting of bearing easily and press-fits.
3. this product highly versatile through overtesting, only needs each element size of bearing dismounting device is suitably adjusted, i.e. the bearing removal of the different size that uses applicable to the present railway freight-car of China and press-fiting.
4. it is as follows to use bearing dismounting device of the present invention to carry out the operating process of bearing press mounting:
1. adjust the Shifting bearing changer, make its oil cylinder piston bar concentric with the axletree that needs pressing bearing;
2. trussed shore is fixed on the axletree end that needs pressing bearing with the axle head bolt;
3. bearing is inserted in trussed shore, and pushes the axletree end to;
4. connector is tightened to Shifting bearing changer oil cylinder piston boom end;
5. gland is inserted in the trussed shore end;
6. start the Shifting bearing changer, piston rod is ejected the appropriate location;
7. insert bearing pin, by bearing pin connector is connected with trussed shore;
8. rotates Shifting bearing changer operation valve handle, the oil cylinder piston bar is regained, make piston rod pulling working head and trussed shore, and the pulling axletree enters bearing 7, in other words in relative motion by gland with the bearing roof pressure outside axletree.
5. it is as follows to use the present invention to carry out the bearing removal operating process:
1. adjust the Shifting bearing changer, make its oil cylinder piston bar concentric with the axletree that needs the dismounting bearing;
2. with the top cover screwing to Shifting bearing changer oil cylinder piston boom end;
3. be inserted into arm-tie on the axletree that needs the dismounting bearing (contacting with the bearing backstop) from top;
4. four pull bar homalocephalus one ends are inserted in four axis holes of arm-tie, the other end inserts portable axle
Hold in four axis holes of changer, and nut is screwed into the appropriate location, the nut of four pull bars is screwed into position consistency;
5. with the pull bar half-twist, make it can't break away from arm-tie;
6. start the Shifting bearing changer, rotating operation valve handle goes out the oil cylinder piston masthead, thereby by arm-tie and pull bar bearing is backed off.
