Installation of the Slewing Ring on Site:
Optimal service life requires supports of the same quality as the slewing rings. Rollix offers flatness checks and assembly supervision. Services include validation of support flatness, surface reworking, installation, and start-up tests. Bolt tightening is performed using hydraulic tensioners or wrenches.
In-House Laboratory:
Tests on metallic materials, thermoplastics, and elastomers, including mechanical, metallographic, heat treatment, salt spray, and viscosity tests.
Slewing Ring Inspection:
On-site inspections may be required based on environmental constraints. Videoscopy surveys visualize the raceway condition. Lubrication analysis is conducted periodically or punctually.
On-Site Customer Services After Commissioning:
Thorough inspections determine wear levels and assess retrofitting possibilities. Functional and visual checks are conducted, and expert reports are provided.
Composition of a Slewing Ring:
Component Parts: Includes gears, rolling elements, fastening holes, lubrication holes, and protective seals.
Ring Materials: Uses fine carbon steel grades and other materials like stainless steel, bearing steel, and titanium alloys for specific applications.
Sealing Solutions: Various sealing options protect raceways and maintain lubrication.
Rolling Elements: Supplied according to precise specifications and validated by Rollix's laboratory.
Cages and Spacers: Designed to meet customer requirements using different materials or coatings.
Slewing Ring Characteristics:
Estimating Loads: The slewing ring must transmit forces from a moving part to a fixed base. It is essential to specify the resulting torsor applied to the slewing ring's center.
Defining Application Criteria: Factors like utilization, safety, and application are considered to design and size the slewing ring's bearing function.
Selecting the Slewing Ring: The load capacity is calculated based on geometric envelope, materials, heat treatments, rolling elements, and contact parameters.
The document outlines specifications for slewing rings, focusing on load calculations and fastening methods. The application point P, determined by axial load and tilting moment, must remain below the limit curve for safety. Fastening is crucial, with bolting preferred over welding. Bolt quality is defined by ISO 898-1, recommending high-strength bolts of class 10.9, with nuts of equal or greater class.
Fastening and Installation
Proper mechanical fastening to the chassis is essential for force transmission. The document advises against welding and emphasizes the importance of bolt quality and installation. Counterbores are recommended to enhance force transmission and prevent sliding.
Service Life and Maintenance
The service life of slewing rings, whether for continuous or partial rotation, must be regularly checked. The document suggests contacting Rollix for gear life verification.
Load Calculations
Rollix provides calculation rules based on standards like AFNOR FD E 25.030 and VDI 2230. Supported loads should be evenly distributed, and friction coefficients should exceed 0.2. The document details torque calculations, including starting and rotating torque, with examples provided.
Environmental and Operational Conditions
Slewing rings operate between -25°C and +70°C, with specific designs for extreme temperatures. Aggressive environments require protective measures, and continuous shocks or vibrations must be considered in the design.
Installation Recommendations
Chassis design must ensure sufficient stiffness to prevent deformation. Support thickness and shape tolerances are specified to ensure even pressure distribution and prevent bearing damage. Epoxy resins can be used to correct surface defects.
Transport and Storage
Slewing rings are packaged to prevent transport damage, with options for long-term storage and specific transport methods for large diameters.
Slewing rings must be handled carefully to avoid shocks. They should be stored in a covered, tempered room with humidity below 85% and temperature above 12°C. For long-term storage or specific conditions, special packaging is required. Lubrication is necessary every 18 months.
During unpacking, avoid cutting protective seals. Use non-chlorinated thinners for degreasing. Position the soft zone at 90° to the main load axis. Each slewing ring is identified with a metal label. Installation markers include gear run-out and soft zone indicators.
Ensure the structure is suitable for installation. Elastic washers are prohibited; use Nord-Lock type washers. Tighten bolts using a calibrated tool, following the star method. Recommended tightening torque values are provided based on bolt diameter.
Position the pinion 90° from the main load axis and adjust to the maximum gear run-out point. Ensure proper alignment and lubrication before operation.
Rotate the slewing ring to check for hard spots and verify gear run-out. Measure deflection under load and record values in the inspection booklet.
Regular lubrication is crucial for longevity. Use lithium soap-based grease with specific viscosity and additives. Regreasing intervals vary based on operating conditions. Preventive controls include seal and fastening monitoring, and slewing monitoring.
Monitor deflection under load to assess wear. Replace the slewing ring if deflection exceeds safe limits. Follow regulations based on application.
