Product catalog summary
Company Overview: Power Jacks is a UK-based leader in manufacturing actuation, lifting, and positioning solutions for sectors like Industrial Automation, Energy, Defence, Medical, Transport, and Civil Engineering. They are the largest screw jack manufacturer in the UK, adhering to BS EN ISO 9001, OHSAS 18001, and ISO 14001 standards.
Bevel Gearbox Range-N Overview: The Range-N series features ultra-compact spiral bevel gearboxes designed for high torque and smooth transmission, suitable for industrial and extreme environments such as subsea, defence, or nuclear.
Features: These gearboxes include precision spiral bevel gears, superior gear and shaft support, and various shaft configurations. They are designed for a service life of 10,000 hours and can handle input speeds up to 3000 rpm. The housing is made from durable SG Iron with corrosion protection options.
Product Code and Selection: A detailed product code system allows customization based on gearbox type, shaft configuration, material, and environmental ratings. A selection guide assists in choosing the appropriate gearbox based on input/output speed, torque, and operating conditions.
Performance and Specifications: Available in six sizes with gear ratios from 1:1 to 4:1, supporting power ratings from 0.1 to 226 kW and torque ratings from 15 Nm to 7000 Nm. Optional features include motor adapters and subsea configurations.
Conclusion: Power Jacks' Bevel Gearbox Range-N offers precision and reliability with a wide range of configurations to meet diverse industrial needs.
Gearbox Selection and Calculation Process:
Corrected Output Torque Calculation: Multiply the required output torque by factors f1, f2, and f3. For multiple output shafts, sum the individual torques.
Corrected Output Power Calculation: Use the formula: Required Output Torque x Output Speed / 9550.
Required Input Power Calculation: Divide the output power by gearbox efficiency (95%-98%).
Gearbox Selection: Select a gearbox with adequate rated power from the Gearbox Torque x Power Rating Table.
Thermal Capacity Check: Calculate the thermal capacity using the limiting thermal capacity and factors f4 and f5.
Final Capacity Check: Consider the effect of connected drive systems on shaft loading.
Operational Conditions: Used with an electric motor and clutch mechanism on a heavy-duty stacking machine, operating 10 hours per day with 8 starts per hour at 20°C ambient temperature.
Gearbox Specifications: Series 39 has a nominal torque of 481 Nm, max running torque of 935 Nm, and a thermal limit power of 49 kW. Efficiency ranges from 95% to 98%.
Lubrication and Maintenance: Gearboxes are shipped without lubrication. Use ISO 220 gear oil for ambient temperatures between +5°C and +40°C.
Load Factors and Thermal Limits: Consider shock load, starting frequency, and transmission load factors. Ensure the case temperature does not exceed 80°C.
Permissible Shaft Loading: Check radial and axial loading against permissible levels.
Specifications: Detailed specifications include dimensions, torque values, input speed, thermal limit power, efficiency, and service life. Various configurations are available.
Procedures: Outlines procedures for selecting and configuring gearboxes, including subsea design features.
Standards and Norms: Dimensions are in millimeters, and motor adapters use a B5 IEC flange.
Recommendations: Stainless steel gearboxes are recommended for high corrosion resistance applications.
Accessories and Options: Includes special gear ratios, motor flanges, lightweight designs, and corrosion protection.
Performance Data: Series 42 includes nominal torque values, maximum running torque, and maximum start-up torque.
Custom Applications: Custom-designed gearboxes are available for specific requirements.
Contact Information: Power Jacks Ltd is located in Aberdeenshire, Scotland, specializing in precision linear actuation, positioning, and lifting equipment.
