Project Name: PM11 Crusher Gearbox Renovation

Project Time: 2023

Selected model: QVRL2-CUN

Delivery quantity: 1 unit

Design advantage: Designed in Belgium, with a focus on transforming liquid nitrogen cold packaging. The assembly tolerance fit is strictly in accordance with the original standards, ensuring that the service life of high-speed shafts and intermediate shafts is not less than 50000 hours, and the service life of low-speed shaft bearings is not less than 100000 hours.

Transformation focus: The original OIL LOCK sealing structure used on the high-speed end of this gearbox did not take into account the dust and humid environment during use. The sealing ring has a small contact surface with the high-speed shaft, which is prone to oil leakage. The high-speed end flange has been redesigned and replaced with a double lip multi-layer structure to achieve the best use effect.
