What are the daily maintenance procedures and correct installation steps for parallel-shaft helical gear reducers?

Every mechanical product has its own core components. For the Lieming gear reducer, these components are also crucial in daily maintenance. The key parts of a gear reducer can be said to include the exterior and electrical components. So, what are the steps for the daily maintenance and proper installation of a parallel-shaft helical gear reducer?

What are the daily maintenance procedures and correct installation steps for parallel-shaft helical gear reducers?

1. Appearance Maintenance of Lieming Gearbox Components: Clean the outer surface of the lathe and all covers, keeping both the interior and exterior free of rust and oil stains. Also clean the three crossbars. Inspect all screws, handle balls, and handles. After cleaning and wiping, lubricate all components as required.

2. Maintenance of Liming reducer accessories and electrical components: Clean dust from the motor and the electrical control box. Electrical equipment should be securely and neatly arranged.

Of course, in daily maintenance, you not only need to take care of these specific points but also clean and maintain critical components. Other parts, such as the gearbox, also require regular upkeep.

3. Before installation, confirm that both the motor and the gearbox are in good condition. Strictly check whether the dimensions of the parts connecting the motor and the gearbox match. The following are the dimensions and fit tolerances for the motor positioning boss, input shaft, and gearbox slot.

4. Unscrew the screw on the dust hole on the outer side of the reducer flange, adjust the clamping ring of the PCS system so that its side hole aligns with the dust hole, and insert the hexagonal socket to tighten it securely. Then, remove the key from the motor shaft.

5. Connect the motor to the reducer naturally. During connection, the concentricity between the reducer’s output shaft and the motor’s input shaft must be consistent, and the outer flanges of both components should be parallel. Inconsistent concentricity can lead to motor shaft breakage or wear of the reducer gears.

6. Additionally, during installation, it is strictly prohibited to strike components with a hammer, as excessive axial or radial forces could damage the bearings or gears. Before tightening the pressure bolts, make sure that the mounting bolts have been properly tightened. Prior to installation, use gasoline or zinc-sodium solution to wipe away the anti-rust oil from the motor input shaft, the locating boss, and the connection point between the ZJY reducer. The purpose of this step is to ensure a tight connection and smooth operation, while also preventing unnecessary wear. Before connecting the motor to the reducer, align the keyway on the motor shaft vertically with the fastening bolts. To ensure even distribution of force, first tighten any two diagonally opposite mounting bolts—but do not fully tighten them yet. Then proceed to tighten the other two diagonally opposite mounting bolts, gradually tightening all four mounting bolts one by one.

7. Tighten the bolts. All fastening bolts on the gear reducer must be tightened and checked using a torque wrench according to the specified torque values. Please note that the relevant data for right-angle reducers differs slightly from those of straight-line reducers of the same type. Proper installation between the reducer and mechanical equipment is similar to proper installation between the reducer and the drive motor. The key is to ensure that the concentricity of the reducer’s output shaft matches the concentricity of the driven shaft.
