ZLSH17-H RATIO 50/80:1 High Precision Harmonic Gearbox For Robotics
And Various Industrial Automation Applications
1. Products Overview
Harmonic reducers, or harmonic gearboxes are mainly composed of
four basic components: wave generator, flexible gear, flexible
bearing, and rigid gear. Harmonic transmission reducer is a kind of
flexible bearing with a wave generator to produce controllable
elastic deformation of the flexible gear and it transforms the
force by meshing with rigid teeth.
Products Features
The transmission ratio is larger. The ratio of a single-stage harmonic gear transmission rate is 70
~ 320:1, can reach up to 1,000:1 in certain harmonic reducers, and
the multi-stage transmission speed ratio can reach more than
30,000:1.
High carrying capacity. This is because the number of teeth that meshing at the same time
in the harmonic gear transmission can be more than 30% of the total
number of teeth at the same time, and the soft wheels use
high-intensity materials, and the tooth is connected with facial
contact.
High transmission accuracy. This is because the number of teeth in the harmonic gear
transmission at the same time and, the multi-tooth mesh has a
mutual compensation effect on the error, so the transmission
accuracy is higher. In the case of the same gear accuracy level,
the transmission error is only about 1/4 of ordinary cylindrical
gear transmission.
High drive efficiency and stable exercise. Because the soft wheel teeth moved a uniform radial movement
during the transmission, even if the input speed is very high, the
relative slip speed of the wheel teeth is still extremely low. So
the wheel's teeth wear is small, high efficiency (can reach 69%~
96%). Due to the entry and meshing, both sides of the gear
participated in the work, so there was no impact, and the exercise
was stable.
Simple structure, small number of parts, and convenient
installation. There are only three basic components, and the input and output
shaft coaxial rays, so the structure is simple and easy to install.
Small volume and light weight. Compared with the regular reducer, when the output torque is the
same, the volume of the harmonic gear reducer can be reduced by
2/3, and the weight can be reduced by 1/2.
Suitable for closed space application. Using the flexible characteristics of soft wheels, this valuable
advantage of rotation is incomparable to other transmission.
Applications
Harmony reducer is a flexible gear transmission device. Because of
the advantages of small size, light weight, and large bearing
capacity, it is widely used in various automation fields.
• Aerospace. Harmonic reducer plays an important role in the field
of aerospace and is used to meet the requirements of high precision
and reliability.
• Energy and navigation. Equipment in these areas often requires a
large amount of force and torque, and harmonic decelerations are
suitable for these applications due to their high carrying
capacity.
• Industrial robot and robotic arm. Harmony reducer improves
exercise accuracy and control in these fields, especially in the
servo system that requires high precision and high dynamic
performance.
• Medical and scientific instruments. These areas have strict
requirements on the accuracy and reliability of equipment, and
harmonic reducer can provide stable and accurate motion control.
• Semiconductor and electronic equipment manufacturing. These areas
have high requirements for the accuracy and micro-operation of the
equipment, and the harmonic reducer can provide high transmission
accuracy and delicate control.
• Petrochemical, textile, agricultural machinery and other fields.
Equipment in these areas usually requires complex motion and force,
and the flexibility and strength of harmonic reducer is very
applicable.
In general, the application of harmonic reducers is very wide. They
play a key role.
