How to adjust the oil level of ZDY160-3.5-1 gear reducer

The key to adjusting the oil level of the ZDY160-3.5-1 gear reducer is to operate it in a stopped state, ensuring that the oil level is between the upper and lower scale lines of the oil mirror or dipstick, and prioritizing control at the middle to upper position. The specific steps are as follows:

1、 Preparation before adjustment

Shutdown cooling: After operation, stop the machine for at least 30 minutes until the oil temperature drops to near ambient temperature (such as 25-35 ℃) to avoid inaccurate readings caused by oil expansion.

Clean the oil level device: Use a clean cloth to wipe off the dust near the oil gauge, oil plug or dipstick hole to prevent impurities from falling into the oil tank.

Check the levelness: Use a spirit level to confirm that the installation foundation of the reducer has a horizontal error of ≤ 0.1mm/m. Tilting can cause the oil level to rise on one side and fall on the other.

2、 Oil level inspection and adjustment methods

Transparent oil label (oil mirror) type:

Looking directly at the "MAX" and "MIN" markings on the oil mirror, if the surface of the oil is clearly visible and between the two, it is considered qualified. It is best to control it to be above the middle.

Built in dipstick type:

Unscrew the dipstick and wipe it clean. Insert it naturally into the dipstick hole (do not tighten it), take it out and check the position of the oil stain. Repeat twice to confirm consistency. The oil stain should be within the "normal range" mark (usually 1/2~2/3 of the total scale).

Oil plug inspection type:

Unscrew the oil level check plug (M16-M24 bolt) on the side of the fuel tank, and if the oil slowly drips out (1-2 drops/minute), it is considered qualified; If there is no oil seepage, oil needs to be replenished, and if there is a large amount of oil gushing out, oil needs to be drained.

3、 Special model supplement

Vertical reducer: The oil level should cover all bearing and gear meshing areas, and 1/2~2/3 of the gear tooth width should be immersed in oil to avoid gear exposure.

Multi stage gear reducer: The lowest stage gear has a tooth width of 1/2 immersed in oil, the highest stage gear is completely immersed, and the middle stage gear has a tooth width of 1/2 immersed in oil, which is a qualified standard.

4、 Key points for oil level maintenance

Oil shortage prevention: Regularly check the oil level to avoid wear caused by insufficient lubrication.

Pollution prevention: Keep the oil level device clean to prevent impurities from entering.

Anti deterioration: Replace the new engine with new oil half a month after the initial refueling, and then regularly replace it according to the instructions.
