Main Structure & features:
The bearing dismount press machine is mainly composed of main frame, left/right main cylinders, dismounting claw devices, wheelset lifting device, receiving device, push wheel device, calibration device, hydraulic system, measuring and electrical control system etc.
- Automatical dismounting both bearings simultaneously.
- Automatical dismounting single bearing separately.
- Manually complete the dismounting as per the working steps. (used during maintenance and commissioning).
- Automatic dismounting under non-load (used in test run).
- Veto for wrong input and incorrect operation.
- The press adopts on-line passing-through arrangement, the wheelset can be pushed out automatically after the bearing is dismounted.
- The press adopts left and right independent valve group for dismounting, ensuring left and right separation dismounting, without left and right string motion and, mutual influence.
- The dismounting mechanism can automatically align with the axis of the wheel set accurately, which is suitable for different wheel diameters.
- The dismounting claw hooks the bearing back cover from above to dismount the bearing. For different types of bearing, only need to change the dismounting pull plate.
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.
