Compared with other reducers, harmonic reducer has the advantages of high precision, high torque, high rigidity and high transmission efficiency. However, the working principle of harmonic reducer also determines that it has many disadvantages. In order to effectively avoid the possible vibration and abnormal noise of harmonic reducer during operation due to assembly errors. Please strictly observe the following precautions for harmonic reducer assembly during assembly.
1. Precautions for wave generator
(1) Please avoid exerting excessive force on the bearing of the wave generator during assembly. The insertion can be performed by rotating the wave generator smoothly.
(2) When using wave generator without Euclidean coupling structure, please pay special attention to control the influence of center offset and skew within the recommended value.
2. Precautions for rigid wheels
(1) Confirm whether the flatness of the mounting surface is good and whether there is skew.
(2) Confirm whether the screw hole is bulged, with residual burrs or with foreign objects.
(3) Confirm whether chamfering and avoidance processing have been carried out on the shell assembly part to avoid interference with the rigid wheel.
(4) After the rigid wheel is assembled to the shell, confirm whether it can rotate and whether there is interference and clamping in some parts.
(5) When inserting the bolt into the bolt hole for installation, confirm whether the position of the bolt hole is correct and whether the bolt contacts with the rigid wheel due to the skew processing of the bolt hole and other reasons, so that the rotation of the bolt becomes heavy.
(6) Do not tighten the bolts to the specified torque at one time. Please temporarily tighten with a force of about 1/2 of the specified torque, and then tighten with the specified torque. In addition, always tighten the bolts in a diagonal sequence.
(7) Pin the rigid wheel may cause low rotation accuracy, so please avoid it as far as possible.
3. Precautions for Flexspline
(1) Confirm whether the flatness of the mounting surface is good and whether there is skew.
(2) Confirm whether the screw hole is bulged, with residual burrs or with foreign objects.
(3) Confirm whether chamfering and avoidance processing have been carried out on the shell assembly part to avoid interference with the flexible wheel.
(4) When inserting the bolt into the bolt hole for installation, confirm whether the position of the bolt hole is correct and whether the bolt contacts with the flexible wheel due to the skew processing of the bolt hole, which makes the bolt rotate heavier.
(5) Do not tighten the bolts to the specified torque at one time. Please temporarily tighten with a force of about 1/2 of the specified torque, and then tighten with the specified torque. In addition, always tighten the bolts in a diagonal sequence.
(6) Confirm whether there is extreme unilateral engagement when combined with rigid wheel. When unilateral offset occurs, it may be due to the center offset or skew of the two components.
As the harmonic reducer is a high-precision component, please strictly follow the installation instructions during assembly to avoid more serious consequences caused by abnormal harmonic reducer
Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
How to provide goods?
Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
What is the payment term?
When we provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
How to ensure the quality of your products?
First, we will check after each process. For finished products, according to customer requirements and international standards.
How many employees does your company have? What is the relationship between technicians?
We now have more than 180 employees, including 36 engineers and 28 QCs.
What is the ability of your company?
We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
