Machine Structure & Features:
The bearing assembly and disassembly press is mainly composed of
main frame, left/right cylinders, dismounting claw devices,
wheelset lifting device, push wheel device, calibration device,
hydraulic system, electrical control system etc.
- This Wheelset Bearing mount and dismount press will be installed in
a foundation pit.
- Able to mount and dismount the rolling bearings onto / off from
axle journals.
- Only a single positioning to complete the fitting and
removal of both bearings.
- Automatical mounting and dismounting both bearings simultaneously
with a single positioning.
- Automatical mounting and dismounting single bearing separately.
- Manually complete the mounting and dismounting as per the working
steps. (used for maintenance and commissioning).
- Automatic mounting and dismounting under non-load.
- Overall welding structure, with sufficient strength and rigidity.
- Double cylinders for mounting and dismounting. With special
anti-upsetting centre devices.
- Lifting platform ofr automatic alignment.
- Siemens S7 PLC to control the operation.
- User-friendly human-machine interface.
- The operation system can generate, record, save and print the
pressing curves.
- On-line passing-through arrangement, the wheelset can be pushed out
automatically after the bearing is pressed.
- Unique hydraulic servo system to achieve the variable pressing
speed and ensure the stable and reliable pressure during opeation.
Warranty & After-sale Service:
- The warranty lasts for 1 (one) year from the date of the Site
Acceptance Test of the Equipment.
- During the warranty, the Manufacturer shall be responsible for the
damage due to the defects in design and manufacture.
