The characteristics and protection of running gear surface in period

The characteristics and protection of running gear surface in period
After the medium hard surface helical gear reducer leaves the factory, it usually runs for 200 hours, which is defined according to the technical characteristics of the early application of the hard surface helical gear reducer.However, GE found that due to the lack of application knowledge of hard-tooth helical gear reducers, users still hope to earn income and use small machines as soon as possible, thus ignoring the special technical requirements for the operation of new machines.
1. Operating characteristics of helical gear reducer with hard tooth surface:
1. Wear rate
During the operation of the helical gear reducer with medium hard tooth surface, the solid parts on the part surface are embedded and collide with each other, and the worn metal fragments, as abrasive, continue to intervene in the conflict, causing the wear to double the part surface.At this time, assuming overload operation, it may cause damage to parts and early failure.
2. Poor lubrication
Due to the small joint clearance of the new device components, and due to the device, the lubricating oil is not easy to form a balanced oil film on the friction surface to prevent wear, thereby reducing the lubrication function and causing abnormal wear of the parts.When severe, it can cause severe scratches, surface scratches or bite marks, leading to failure.
2. The application and protection of the helical gear reducer in the period of operation and protection
1. The driver should receive training and guidance, fully inquire about the layout and functions of the reducer, and obtain the necessary driving and protection resumes before driving the reducer.Before driving the reducer, you must first read the application protection simulation board, and drive and maintain it according to the requirements of the imitation coating.
2. Pay attention to workload during period runs.The workload during operation shall not exceed 85% of the rated workload, and an appropriate workload shall be arranged to prevent overheating caused by long-term continuous operation.
