Designed for continuous operation under severe conditions, the DP series provides reliable power transmission across various heavy industries. Its high torque capacity and shock load resistance make it the ideal choice for critical equipment setups, significantly reducing the risk of unexpected downtime.
Mining and cement: Ideal for apron conveyors, bunker dischargers, and scratchers, providing consistent driving force even in dusty and high-load environments.
Steel Production: Engineered for pilger rolling mills and reversing rolling mills, ensuring precise speed control and enduring extreme operational stress.
Food and beverage: Suitable for heavy-duty industrial mixers, delivering stable output for consistent product quality.
Other fields of application: Widely utilized in chain conveyors and material handling systems, offering long-term reliability.
To ensure seamless integration into your existing machinery and reduce installation complexity, the DP Series offers a variety of mounting configurations. This versatility allows engineers to select the most efficient setup for their specific mechanical requirements.
Cylindrical shafts with parallel keys for standard, reliable connections.
Cylindrical shafts with splines for high-torque, heavy-duty transmission.
Hollow shafts with shrink disc for backlash-free, secure friction fits.
Hollow shafts with splines for compact and robust integration.
Flanged shafts designed for direct and stable equipment mounting.
The durability and efficiency of our Cast Iron Coaxial Planetary Gear Speed Reducer stem from rigorous gear processing technologies. We utilize premium 20CrMnTi materials and advanced heat treatment to maximize gear life and optimize overall transmission performance.
Sun and planet gears: Sun and planet gears have spur gear teeth and are case-hardened and precision-ground to ensure smooth engagement and high load-bearing capacity.
Annulus gears: Annulus gears are mostly quenched and tempered and shaped or ground, depending on specific size and torque requirements, to maintain structural integrity.
Bevel gears: Bevel gears are case-hardened and, depending on size, lapped, HPG-cut or ground, ensuring efficient power redirection and reduced noise levels.
Primary gear: The gears and gear shafts of the primary gear stages have helical teeth and are case-hardened and ground, providing superior contact ratios and efficient torque transfer.
The DP series includes not only the highly integrated planetary gear motor but also maximum conformity with all international motor standards, ensuring that quality and performance bear a sensible relationship to life cycle costs and price. Furthermore, specialized options such as temperature control, explosion protection, taconite seals, a design for extreme temperatures down to -40℃, and various mounting options guarantee optimal availability and fail-safe operation even under demanding conditions.
To ensure optimal performance and compatibility, please provide our engineering team with the following details:
Based on these parameters, we will recommend the most suitable and cost-effective model for your project.
Both DP and HB series reducers are suitable for applications requiring very high torque output. Compared to the traditional H/B series helical/bevel gearboxes, the DP series features a relatively smaller volume, a more compact coaxial design, and easier installation in space-constrained environments.
