Coaxial Base-Mounted Planetary Gear Box Industry Knowledge

What is the assembly process of the coaxial base planetary gearbox? What key steps are included?

Preliminary preparation and component inspection
1. Technical data preparation
Before the assembly begins, it is necessary to ensure that all technical drawings, assembly guidelines, quality control standards and other documents are complete and up-to-date. The company uses the design concept synchronized with the international to ensure that these documents not only meet domestic standards, but also meet international advanced standards.
2. Component inspection
All components are strictly inspected before entering the factory, including but not limited to planetary gears, sun gears, inner rings, bearings, shafts, housings, flanges, etc. High-precision measuring equipment such as three-coordinate measuring machines and gear measuring centers are used to ensure that the dimensional accuracy, surface roughness, heat treatment quality, etc. of the components meet the design requirements. In addition, for key components such as planetary gears and bearings, the company uses the same raw materials and manufacturing processes as internationally renowned brands to ensure their durability and reliability.

Pretreatment before assembly
1. Cleaning and oiling
All components must be thoroughly cleaned before assembly to remove impurities such as oil stains and iron filings to ensure the cleanliness of the assembly environment. Subsequently, apply an appropriate amount of anti-rust oil or grease to the key contact surfaces to reduce friction and wear during assembly.
2. Pre-assembly and adjustment
Before formal assembly, pre-assembly is performed to check the fit of each component, such as the clearance between the shaft and the bearing, the gear and the gear ring, etc. According to the pre-assembly results, the necessary components are fine-tuned to ensure the accuracy and performance after assembly.

Formal assembly process
1. Assembly of the housing and base
First, fix the base on the assembly platform, and then install the housing. Through precise positioning and tightening, the coaxiality and verticality between the housing and the base are ensured, laying the foundation for subsequent gear assembly. The company uses advanced processing and testing equipment to ensure the processing accuracy of the housing and the base, thereby improving the overall assembly accuracy.
2. Shaft system assembly
Shaft system assembly is a key link in the assembly of coaxial base-mounted planetary gearboxes. Install the input shaft (including N standard shaft input, MN flange input, etc.) and the output shaft (such as cylindrical shaft, spline shaft, etc.) into the housing. During the assembly process, the axial and radial clearances of the shaft are strictly controlled to ensure the smooth operation of the shaft system. Use high-precision bearings and seals to improve the bearing capacity and sealing performance of the shaft system.
3. Assembly of planetary gear sets
The assembly of planetary gear sets is the key to ensuring the reliability of power transmission. Assemble the planetary gears, sun gears and inner ring gears into the housing accurately according to the design requirements. During the assembly process, pay special attention to the meshing clearance and contact spots of the gears to ensure good meshing of the gears and reduce noise and wear. The company uses advanced gear processing and testing technology to ensure that the accuracy and performance of the gears reach the international advanced level.
4. Locking and adjustment
After the assembly of the planetary gear set is completed, the output shaft is locked and adjusted. According to the output torque range and speed ratio requirements, select appropriate locking discs and hollow shafts and other components to ensure the stability and reliability of the output shaft. At the same time, debug the lubrication system of the gearbox to ensure that the lubricating oil is supplied sufficiently and evenly.

Quality inspection and testing
1. Assembly quality inspection
After the assembly is completed, the coaxial base-mounted planetary gearbox is subjected to comprehensive quality inspection, including appearance inspection, dimensional measurement, functional testing, etc. Using advanced testing equipment, such as vibration analyzers and noise testers, the vibration, noise and other performance of the gearbox are monitored and analyzed in real time.
2. No-load and load tests
No-load and load tests are carried out to simulate actual working conditions and check the operation of the gearbox. Through testing, potential problems can be discovered and solved in time to ensure that the performance of the gearbox meets the design requirements.
Packaging and delivery
After passing the quality inspection, the coaxial base-mounted planetary gear box is professionally packaged to ensure that it is not damaged during transportation. At the same time, a detailed packing list and operation manual are provided to facilitate customers to install and use after receiving the goods.
