Why Robot Precision Cycloidal Reducer?

ZURICH - March 28, 2024 - PRLog -- Since industrial robots require high precision, high stiffness and long life of reducer, there are strict requirements on materials, facilities, techniques and other series of processing capabilities, these make reducer become the highest technical threshold among the three core parts of industrial robot. This key component has the highest influence on the performance of robot and is the most central profit source of the whole robot industry chain.

Huge investment and technical barrier lead to the oligopoly condition of current global reducer market. There are only two monopolies taking over the 75% world utility. As a result, robots industry have few speaking rights on the reducer price negotiation table.

Precision Cycloidal ball reducer is a significant invention in the field of precision motion control, it overturns the 100-year old history of traditional gear drive technology, and illustrates epoch-making influences on the robotic industry.

Since all the driving steel balls move evenly and simultaneously over the cycloidal disks for eccentric motion, speed is going through two-stage differential reduction, there is only rolling contact between the steel balls and the cycloidal trajectory, thus full-contact-rolling transmission mode with low friction, high efficiency, high precision, zero backlash, bestow reducer with low temperature rise and low wear, low noise, high impact resistance, long design life, life expands to be equivalent to steel bearing.

Speed reduction ratios range from 5 to 10K with many choices. Simple structure contains short transmission chain, only 4 core parts, so that the reducer looks flat , with small volume and lighter weight. Furthermore, it can be connected with any motors.

According to the one-principle, multiple structures, cycloidal reducer can be applied to almost all kinds of industrial or service robot joints, can be consolidated into the internal wheel frame, can be used in various automation solutions, high rigidity, high efficiency and 'long as bearing' lifetime have been obtained along with precision.

Precision Hub Drive series, accuracy <= 3 arcmin, repeatability at 0.005 mm. Speed ratio is ranged from 15-40, though small size, it has a large loading capacity, multiple wheels allowable torque can reach several tons.

Cycloidal gear boxes fit directly into the mecanum wheel frame, greatly reducing the size of chassis design of mobile robots, building up to a high precision and dexterous omni-directional mecanum wheel, high-load, mobile robot speed reduction drive module.

Precision cycloidal replace planetary reducer, high precision <= 2 arcmin, speed ratios between 5-10K can be selected.
