Engineering Gearbox Planet Carrier

The apertured planetary carrier is a core transmission component of construction machinery reducers, achieving performance breakthroughs through structural innovation. Its core advantages highlight lightweight, precise holes and stable load-bearing: it adopts an optimized hollow structure design, reducing weight by 20%-25% compared with solid planetary carriers and lowering the inertial load of the transmission system; through five-axis linkage CNC machining, the hole positioning accuracy reaches ±0.015mm, and the hole system parallelism error is ≤0.02mm, ensuring precise planetary gear installation; it is forged with 40CrNiMoA alloy steel, and key parts reach HRC45-50 hardness after surface quenching, with load-bearing stability improved by 30% compared with ordinary structures, which can adapt to high-frequency heavy-load working conditions. This product is widely used in the field of construction machinery reducers, suitable for core components such as excavator slewing reducers,…
