Harmonic reducer

---

Product Definition: Harmonic reducers are a new generation of ultra-high precision reduction equipment 

that achieves speed reduction and transmission based on the elastic deformation principle of flexible gears. 

Unlike traditional gear meshing structures, they rely on the cooperation of a wave generator, 

a flexible gear, and a rigid gear to achieve power reduction and torque amplification. They feature small size, 

light weight, large transmission ratio, extremely small backlash, and extremely high positioning accuracy

making them core transmission components for precision automation, robotics, and intelligent equipment. 

As a renowned Chinese brand, Huxing harmonic reducers overcome industry pain points 

such as large backlash

inaccurate positioning, jamming and vibration, short service life

and high import costs associated with traditional precision reducers. 

With their extremely precise transmission performance and stable quality, they are exported globally and 

have gained high recognition and long-term procurement 

from international intelligent equipment manufacturers.

Common Specifications and Models: Huxing harmonic reducers offer a comprehensive specification system

with mainstream models including standard series such as CSD, CSF, SHF, SHG, and LHS. 

These models cover various structures including hollow, solid, ultra-thin, and flat, adaptable to light, 

medium, and heavy-duty applications. All models meet international high-end precision transmission standards 

and can completely replace imported harmonic reducers of the same type

offering exceptional versatility and adaptability.

Basic Technical Parameters: Precision-grade configuration throughout, power ranging from 0.1kW to 5kW, 

rated output torque from 5 to 500 N·m, single-stage speed ratio range from 30 to 160

high single-speed ratio transmission, and extremely high reduction accuracy. Zero/ultra-low backlash

repeatability ≤ ±1 arcsec, and transmission efficiency up to 90%–95%. 

Supports high-speed input and stable low-speed output

adaptable to continuous forward and reverse rotation

high-frequency start/stop, and precision positioning conditions. 

Supports flange and horizontal mounting methods, 

and can be equipped with hollow wire-driven or solid shaft outputs, 

meeting the needs of various precision intelligent equipment.

Materials and Precision Craftsmanship: The core flexible gear is made of ultra-high elasticity special alloy steel

undergoing special tempering and cryogenic stabilization treatment, resulting in excellent elasticity and toughness

fatigue resistance, and resistance to repeated deformation. 

It is not easily broken or aged under long-term high-frequency deformation. 

The rigid gear is made of high-hardness wear-resistant alloy steel, 

treated with precision honing and polishing processes, 

resulting in high tooth surface precision and smooth meshing. 

The entire machine is assembled using micron-level dust-free precision

with accurate clearance calibration. Internal lubrication uses long-lasting high-temperature grease. 

The housing is made of high-strength, lightweight aluminum alloy

providing sufficient rigidity, rapid heat dissipation, light weight, and resistance to deformation.

Huxing's Core Highlights and Competitive Advantages: Compared to ordinary harmonic reducers and 

traditional precision reducers on the market, this product's advantages comprehensively 

surpass those of comparable products. First, ultra-high precision with zero backlash; the return backlash

is nearly zero, ensuring accurate positioning and eliminating idle error

perfectly suited for high-precision positioning scenarios.

Second, small size and high torque; compact and lightweight structure

achieving high torque output in a very small space

far exceeding the transmission performance of traditional planetary gearboxes.

Third, extremely smooth and quiet operation; no gear impact, gentle meshing

no vibration or noise during start-stop, suitable for high-end, quiet precision equipment.

Fourth, ultra-long fatigue life; the flexible gear has excellent deformation resistance

allowing for long-term, high-frequency reciprocating operation without fatigue damage.

Fifth, maintenance-free and cost-effective; long-lasting sealing and lubrication

requiring no frequent maintenance, can replace expensive imported products

significantly reducing equipment procurement and maintenance costs.

Wide Application Scenarios: Widely compatible with high-precision, high-positioning

and lightweight transmission scenarios such as industrial robots, robotic arms

automated precision modules, intelligent warehousing equipment, medical precision instruments

aerospace components, optical testing instruments

high-end intelligent equipment, and semiconductor equipment. 

Relying on stringent precision machining standards and comprehensive precision testing, 

Huxing harmonic reducers, with their core advantages of high precision, zero backlash, 

lightweight, long life, and high stability, have broken the monopoly of imported brands 

and become a benchmark for high-quality domestic products 

in the global high-end precision transmission field.
