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, measuring and electrical control system etc.
- This Wheel Bearing mount and dismount press will be installed in a foundation pit.
- It's able to mount and dismount the rolling bearings onto / off from the axles.
- 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 during maintenance and commissioning).
- Automatic mounting and dismounting under non-load (used in test run).
- Veto for wrong input and incorrect operation.
- Overall welding structure, with sufficient strength and rigidity.
- Double cylinders for mounting and dismounting. With special anti-upsetting centre devices.
- Intelligent lifting platform. It's equipped with wheel locking mechanism, so as to avoid wheelset runout during mounting and dismounting and ensure the stability of the pressing force.
- 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.
- After the warranty period, the Manufacturer will provide a wide range of technical support and spare parts with reasonable prices.
