HB Series Industrial Gear Units

Product Details

New generation HB series industrial gearboxes boast excellent load-bearing capacity, standard interface dimensions, and modular design and manufacturing. They can interchange with international brands in terms of size, torque, and power capabilities. Stability and consistency are outstanding, with 100% localization. The main product features include:

Comprehensive benchmarking:

• Load-bearing capacity calculation standards for helical gears comply with GB/T3480, DIN3990, and ISO6336.
• Load-bearing capacity calculation for bevel gears conforms to DIN3991 and ISO10300.
• Comprehensive upgrade in power transmission and torque capabilities.
• No more ambiguous reliability coefficients in selection.

Product validation:

• Rigorous full-load fatigue testing under various nominal torque capacities ensures the reliability of related aspects of Guomao HB products, including:
  • Effectiveness of gear load-bearing capacity calculations.
  • High-quality casting and forging raw material.
  • Bearing selection and life calculation effectiveness.
  • Manufacturing process capability and machining accuracy.
  • Assembly precision.

Rich configurations:

• Highly modular with fewer types of components, forming a series of gearbox specifications.
• Can be installed horizontally or vertically, or in other forms as per user requirements.
• Various lubrication and cooling methods can be selected based on operating conditions, such as fans, external circulating oil systems, air coolers, etc.
• Different sealing forms can be chosen according to different working conditions.
• Flexible switching between imported and domestic bearings configurations.
• Free switching between cast and welded housings.

System assurance:

• Control system for forging raw materials and heat treatment.
• Supply chain of high-quality carburized steel forgings from mainstream brands.
• High dimensional and positional tolerance grades for housing.
• Gear pair meshing accuracy reaches grade 6, while low-noise profiling technology ensures smooth operation.
• Modern logistics and warehousing system effectively guarantee the precision, accuracy, and timeliness of parts.
• Clean assembly process, meticulous assembly operations, and strict factory testing.

Operating characteristics:

• Gears designed for infinite life.
• Bearing life exceeds 50,000 hours when service factor (S.F.) >= 1.4; all bearings have a lifespan of over 100,000 hours when S.F. >= 1.6.
• Excellent noise performance, with models below size 14 having noise levels <=85db and other models not exceeding 90db.
• Outstanding transmission efficiency, with helical gear pair efficiency reaching 98.5% and bevel gear pair efficiency reaching 97.5%.
