ZLSH17-H Series Harmonic Low Noise Gear Reducer High Torque Speed Wave Generator

ZLSH17-H Series High Torque&Speed Low Noise Hamonic Gear Reducers Wave Generator for CNC machine Industrial Automation

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.
