How to ensure the correct phase of the cycloidal wheel of the BLEY2715-1003-0.75KW reducer during the assembly process

Assembling cycloidal pinwheel reducers such as BLEY2715, ensuring the correct phase of the cycloidal gear is the core, which directly affects the transmission accuracy and service life. The following are the key operational points:

1、 Preparation and inspection before assembly
Check the pairing of cycloid gears: Ensure that the two cycloid gears are the original pair, and check whether their bearing holes, ten holes (shaft pin holes), and external tooth profiles can completely overlap. If they cannot overlap, they cannot be used as a pair.

Confirm marking direction: Carefully examine the steel stamp markings (such as "A" or numbers) on the cycloidal gear. During assembly, it is necessary to ensure that the marked directions of the two cycloidal gears are 180 degrees apart. This is the foundation for ensuring the correct phase.

Clean working environment: Before assembly, the working area and all components must be thoroughly cleaned to prevent dust and impurities from entering the interior of the gearbox, so as not to affect transmission accuracy and accelerate wear.

2、 Key operations during the assembly process
Install the first cycloid gear: Place the first cycloid gear into the needle gear housing, ensuring that the side marked with the steel seal faces upwards.

Install eccentric bearing and spacer ring: Install the eccentric bearing (arm bearing) into the bearing hole of the first cycloidal wheel, ensuring that the ball is completely contained. Then insert the spacer ring.

Install the second cycloidal gear (phase control core):

Rotate the second cycloid wheel 180 degrees so that its mark is symmetrical with the direction of the mark on the first wheel.

Place it inside the needle housing, ensuring that its steel stamp mark is on the same straight line and in the opposite direction as the mark on the first piece.

Manual rotation inspection should be able to rotate smoothly without any jamming or swinging phenomenon.

Install the shaft sleeve and end cover: Finally, install the shaft sleeve and install the end cover, snap spring, and other components. During the installation process, attention should be paid to the direction of the lifting point and the needle tooth housing air outlet to ensure that the reducer is placed horizontally.

3、 Inspection and trial operation after assembly
Comprehensive inspection: Check whether all components are installed in place, whether the seals are intact, and whether the lubricating oil is filled to the specified level.

Test run: Conduct a no-load test run to check if the transmission is stable, and if there are any abnormal noises, vibrations, or temperature rises. If there is any abnormality, the machine should be stopped immediately for inspection.

4、 Precautions
Use specialized tools: During installation and disassembly, specialized tools should be used to avoid rough handling that may cause damage to parts.

Keep clean: The entire assembly process must be kept highly clean, as any impurities may cause early failure.

Follow the process: Strictly follow the assembly process and drawing requirements provided by the reducer manufacturer for operation.

Summary: The core of ensuring the correct phase is to confirm that the cycloidal gear is the original configuration, strictly stagger the marking direction by 180 degrees, and cooperate with a clean assembly environment and standardized operation. Careful inspection and trial operation must be carried out after assembly.
