The R&D and Application Project for Hub Drive Planetary Transmission Bearings in Large Mining Trucks by ZWZ Won Second Prize
Recently, the list of award-winning projects in the Liaoning division of the "Spark" Innovation and Creativity Competition for state-owned enterprises in the "Three Northeast Provinces and One Region" was announced. ZWZ secured two spots on the list: its "R&D and Application of Bearings for Large Mining Truck Wheel Hub Drive Planetary Transmission Devices" project won second prize, while the "R&D and Manufacturing of Suspension Bearings for Passenger Vehicle Shock Absorption Systems" project received an excellence award.
1.Second Prize Project: "R&D and Application of Bearings for Large Mining Truck Wheel Hub Drive Planetary Transmission Devices"
This project addresses the issue of core bearing components for large mining trucks relying on imports. Through multi-dimensional longevity design and quality control technology development, it resolves challenges such as bearing clearance, insufficient lubrication, and premature fatigue at weak points. By adopting simulation technology, low-friction lubricated gradient vulcanization layer control technology, and micro-deformation control technology for thin-walled bearing heat treatment, the project successfully achieved domestic substitution, breaking foreign monopolies and meeting customer demands.
2.Excellence Award Project: "R&D and Manufacturing of Suspension Bearings for Passenger Vehicle Shock Absorption Systems"
This project focuses on the development of suspension bearings for passenger vehicle shock absorption systems. Through technological innovation, it enhances product performance. While specific technical details were not disclosed in the search results, the project earned an excellence award for its innovation and practical application value.
Organized by the State-owned Assets Supervision and Administration Commission of Liaoning Province, this year's competition attracted 241 enterprises submitting 506 projects across various fields, including advanced manufacturing and new energy, aiming to promote the integration of innovation and industrial chains in state-owned enterprises.
