Problems solved by technology
[0003] For the disassembly of the large bearing of the integral gearbox, there is no special equipment at present. Many maintenance factories use self-made disassembly tooling. This method is not only irregular, inconvenient to operate, but also has potential safety hazards, which is easy to damage the axle and gearbox

Embodiment Construction
[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] A gearbox bearing dismounting device, used for disassembling the large bearing 2 in the gearbox assembly. The gearbox assembly includes an axle 1, a large bearing 2, a gearbox 3 and a large gear 4. The large bearing 2 includes two parts located at the large gear 4. The large bearing 2 on the wheel side and the large bearing 2 on the motor side are provided with axial holes 31 on both axial sides of the gearbox 3, see figure 1 , 2 shown.
[0026] Referring to 3, 4, 5 and 6, the dismounting device includes a base 5, a sliding gear box moving platform 6 installed on the base 5 and a claw assembly 7, the sliding direction of the gear box moving platform 6 and the pulling claw The sliding direction of the assembly 7 is vertically arranged, and the claw assembly 7 can also be installed on the base 5 vertically, and...

The gearbox bearing dismounting device comprises a base, a gearbox moving platform installed on the base in a sliding mode and a pull claw assembly, the sliding direction of the gearbox moving platform is perpendicular to the sliding direction of the pull claw assembly, and the pull claw assembly can be installed on the base in the vertical direction in a lifting mode. An axle supporting seat used for supporting an axle is arranged on the gear box moving platform, the axle supporting seat can be installed on the gear box moving platform in a lifting mode, the two sets of pulling claw assemblies are used for disassembling a wheel side large bearing and a motor side large bearing respectively, and each set of pulling claw assembly comprises a pulling claw arm, a pulling claw head, an insertion plate and an insertion block. A withdrawal oil cylinder is further installed at the end, away from the pull claw head, of the pull claw arm, and when the large bearing is detached, the output end of the withdrawal oil cylinder abuts against the shaft end face of the axle. The dismounting device is simple in structure, convenient to operate and high in working efficiency.
Description
technical field [0001] The invention relates to the technical field of dismantling equipment for gear box bearings, in particular to a dismantling device for a large bearing of an EMU and a subway gear box. Background technique [0002] When the gear box assembly of the EMU is overhauled, it is necessary to disassemble and replace the large bearing. The method of disassembling the large bearing is to use the claw to clamp the end face of the inner ring of the large bearing, and pull the claw to remove the large bearing. The disassembly of the large bearing of the split gearbox is relatively easy. For the integral gearbox, the large bearing needs to be disassembled from the bearing seat hole of the gearbox. Because the gap between the gearbox bearing seat hole and the large bearing is limited, and the inside of the large bearing The space between the end face of the ring and the large gear is small (generally no more than 12mm), and the dismounting force of the large bearing ...
