Product catalog summary
Overview: The document provides detailed technical specifications for a range of gearboxes offered by Mijno. These gearboxes are designed for heavy-duty applications with high torque and low backlash, suitable for servo applications. The document emphasizes the customization options available for specific needs.
Key Specifications:
  • Torque and Speed: Gearboxes support up to 10,100 Nm rated torque with input speeds up to 4,000 rpm. Custom solutions are available for higher speeds.
  • Backlash and Stiffness: Very low backlash (5 to 1 arc-min max) and high torsional stiffness are highlighted, ensuring precision in power transmission.
  • Design Features: The gearboxes feature a rotating output flange supported by angular contact or tapered roller bearings, enhancing radial and axial load capacity.
  • Ratios and Interfaces: Standard ratios range from 3 to 220, with custom ratios available. ISO or DIN output interfaces are provided.
  • Environmental and Safety Features: Standard protection is rated at IP 65, with options for IP-67 and 1500 psi water jets. A washdown stainless steel version is available, along with optional lubricating grease for food-processing applications.
  • Durability: Estimated gear life is 20,000 hours, with emergency stop torque rated at 2.5 times the rated output torque for up to 1,000 times during the gearhead's life.
Technical Characteristics by Model:
  • BDB 120: Offers up to 85 Nm rated output torque, with a weight range of 5-10 kg depending on the number of stages.
  • BDB 145: Provides up to 350 Nm rated output torque, with a weight range of 7-13 kg.
  • BDB 180: Capable of up to 1,000 Nm rated output torque, weighing between 15-20 kg.
  • BDB 250: Supports up to 1,900 Nm rated output torque, with weights ranging from 40-55 kg.
  • BDB 300: Delivers up to 3,500 Nm rated output torque, with a weight range of 55-70 kg.
  • BDB 330: Offers up to 7,000 Nm rated output torque, weighing between 65-90 kg.
  • BDB 365: Provides up to 10,100 Nm rated output torque, with weights ranging from 80-120 kg.
General Notes:
  • All models have a gear efficiency of up to 96% at rated torque.
  • Emergency stop torque is consistently 2.5 times the rated output torque for up to 1,000 times during the gearhead's life.
  • Customization is encouraged for specific applications, with the design department available for consultation.
