How to install WB65-WD-29-1 micro cycloidal reducer
The installation of WB65-WD-29-1 micro cycloidal reducer can be carried out according to the following steps:
Pre-installation preparation
Environmental inspection: Ensure that the installation environment is dust-free, dry, with stable temperature, and away from vibration sources and strong magnetic field interference.
Tool preparation: Prepare torque wrenches, hex screwdrivers, vernier calipers, level gauges, etc. with an accuracy level of not less than ± 3%. If conditions permit, laser alignment instruments can be prepared for precise calibration.
Accessory inspection: Refer to the packing list to check if all components of the reducer are complete, with a focus on inspecting key components such as the input shaft, output flange, fastening bolts, and sealing rings for damage, scratches, or rust. At the same time, verify whether the nameplate parameters of the reducer are consistent with the actual requirements.
Lubrication treatment: Select appropriate lubricating grease according to the equipment manual requirements. For example, NLGI grade 2 lithium based lubricating grease can be used in the working environment of -20 ℃~120 ℃. Before installation, apply lubricating grease evenly on the meshing surfaces of the needle teeth and cycloidal gears to achieve a coverage rate of over 80%.
Installation steps
Installation base: Install the base of the reducer in the designated position, ensuring that the installation surface is flat, clean, and free of debris. Use a spirit level to check the levelness of the base, with a levelness error not exceeding 0.5mm/m. If the base needs to be fixed on a concrete foundation, it is necessary to ensure that the compressive strength of the concrete foundation meets the C30 standard, and the pre embedded depth of the anchor bolts is 20-25 times the diameter of the bolts.
Connection between input shaft and drive source: When inserting the motor shaft into the input hole of the reducer, it is necessary to ensure that the coaxiality error of the two axes is ≤ 0.05mm. Laser centering instrument or coordinate measuring instrument can be used for detection. When using an elastic coupling connection, use a feeler gauge to check the distance between the two halves of the coupling, and the deviation value should be controlled within 0.1mm. The fastening bolts need to be tightened three times in diagonal order, and the final torque value should refer to the product manual, usually 18-22N · m.
Installation of output load: Before installing the output flange, clean the oil stains on the joint surface with acetone. The pre tightening force of the bolt needs to be gradually increased, with the first application of 30% of the rated torque, the second increase to 70%, and finally reaching 100%. For servo systems, it is recommended to install clearance washers between the flange and the load to reduce the impact of reverse clearance on positioning accuracy.
Sealing system assembly: When installing double-layer skeleton oil seals, pay attention to the direction, with the main sealing lip facing inward and the secondary sealing lip facing outward. During assembly, it is strictly prohibited to directly tap the sealing components. Special sleeve tools should be used to evenly press them in. After installation, manually rotate the input shaft 3-5 turns to check for any abnormal resistance.
Adjustment and testing after installation
Axial clearance adjustment: The axial clearance can be controlled by adding or removing adjusting shims, with a standard value of 0.02-0.05mm. During inspection, the dial gauge can be fixed on the housing, with the contact pressed against the output shaft end face, and the shaft body can be manually rotated forward and backward to observe the range of pointer swing. If the gap exceeds the standard, the thickness of the gasket can be adjusted according to the actual situation.
