I. Product Overview
The TKM series helical–hypoid gear reducers are a new generation of high‑performance industrial gearboxes. Featuring a hypoid gear transmission design, they deliver significant improvements over conventional worm‑gear reducers in efficiency, noise levels, service life, and installation flexibility, making them widely used in automated equipment across the light‑industry, food, packaging, and textile sectors.
II. Core Structure and Characteristics
- High-efficiency transmission structure
- It employs a helical‑plus‑hypoid gear meshing design, delivering high transmission efficiency (two‑stage efficiency η ≥ 92%, three‑stage efficiency η ≥ 90%) and low energy consumption, with markedly superior energy‑saving performance compared to worm‑gear reducers of the same specifications.
- Low noise, high stability
- The gear meshing boasts high precision, low operating noise, and minimal vibration, making it well-suited for long-term continuous operation in harsh environments.
- Omnidirectional mounting design
- It can accommodate any installation orientation, supports a wide range of application scenarios, offers flexible mounting options, and adapts to diverse equipment layout requirements.
- Durable materials and craftsmanship
- Housing: Die-cast aluminum alloy housing, lightweight, excellent heat dissipation, and corrosion-resistant.
- Gears: Made from 20CrMnTi steel with carburizing and quenching treatment, achieving a tooth surface hardness of 56–62 HRC, offering excellent wear resistance and long service life.
- Surface coating: Standard RAL 9002 light gray finish, corrosion-resistant and oil‑resistant.

IV. Selection and Performance Parameters
- Power and torque coverage
- The frame sizes range from TKM050 to TKM090, corresponding to an output torque range of 130 Nm to 500 Nm, and are compatible with motors of various power ratings (input power is determined based on operating conditions and service factors).
- Selection based on the safety factor (Fs)
- Based on the load type (uniform / moderate / impact), the daily operating duration (2 h/8 h/16 h/24 h), and the start-up frequency, select the corresponding service factor. For impact loads, a safety factor should be applied to ensure the gearbox’s service life.
- Speed adaptation
- The standard input speed is 1,400 r/min; the output speed decreases as the transmission ratio decreases. The higher the transmission ratio, the greater the output torque and the lower the output speed, allowing selection based on the equipment’s process requirements.
V. Typical Application Scenarios
- Industrial Automation: Conveyor Systems, Packaging Machinery, Food Processing Equipment, Textile Machinery
- Light industrial equipment: printing equipment, filling equipment, and auxiliary power for automated production lines.
- General-purpose equipment: mixers, small machine tools, material-handling equipment
