RV reducer introduction

RVis a transmis reducer smission ratio, low vibration, low noise and low energy consumption. It is widely used in industrial robots, machine tools, medical testing equipment, satellite receiving sysion machine with the characteristics of compact structure, large transtems and other fields.
The following is a detailed introduction to RV reducer:

I. Structural composition

RV reducer consists of a front stage of a planetary gear reducer and a rear stage of a cycloidal pinwheel reducer. It is mainly composed of input gears, spur gears (spur gears), crankshafts, RV gears, pin teeth, pin gear housings, planetary carriers and other components.

II. Working principle

The transmission device of RV reducer consists of two parts: the first stage involute cylindrical gear planetary reduction mechanism and the second stage cycloidal pinwheel planetary reduction mechanism, which is a closed differential gear train. Its working principle is as follows:

1. The active sun gear (input gear) is connected to the input shaft. When the sun gear rotates clockwise, it will drive the three planetary gears arranged at 120° to revolve around the axis of the center gear while rotating counterclockwise.

2. The three crankshafts are fixedly connected to the planetary gears and rotate at the same speed. Two cycloid wheels with a phase difference of 180° are hinged on the three crankshafts and meshed with the fixed pinwheel. While its axis revolves around the axis of the pinwheel, it will also rotate in the opposite direction, that is, clockwise.

3. The output mechanism (i.e. the planetary carrier) is driven by the three pairs of crankshaft support bearings mounted on it, and the rotation vector on the cycloid wheel is transmitted at a speed ratio of 1:1.

III. Features and advantages

1. Compact structure: The RV reducer is small in size and light in weight, which is easy to install and maintain.

2. Large transmission ratio: The RV reducer has a large transmission ratio range and can meet the needs of different loads and speeds.

3. Low vibration and low noise: Due to the use of cycloid pinwheel transmission, the RV reducer has low vibration and noise during operation.

4. Low energy consumption: The RV reducer has high transmission efficiency, which can reduce energy consumption and improve the operating efficiency of the equipment.

5. Good rigidity and strong impact resistance: The housing and cycloidal pinwheel of the RV reducer are driven by solid steel, so it has strong load-bearing capacity and is suitable for medium and heavy load applications.

IV. Application fields

RV reducers are widely used in various fields that require precise transmission and control, such as:

1. Industrial robots: RV reducers are key components in industrial robots and are used to achieve precise motion control and positioning.

2. Machine tools: RV reducers are used in machine tools to accurately control the moving trajectory and speed of tools.

3. Medical testing equipment: RV reducers are used in medical testing equipment to accurately control the moving parts of equipment, such as X-ray machines, CT scanners, etc.

4. Satellite receiving system: RV reducers are used in satellite receiving systems to accurately control the direction and angle of antennas.

V. Development trend

With the continuous advancement of technology and the expansion of application fields, the development trend of RV reducers is as follows:

1. High precision: With the continuous improvement of transmission accuracy requirements, RV reducers will develop in the direction of higher precision.

2. Lightweight: In order to meet the needs of lightweight and miniaturization, RV reducers will use better materials and more advanced manufacturing processes to reduce weight.

3. Intelligence: With the continuous development of the Internet of Things and intelligent technology, RV reducers will realize intelligent control and improve the operating efficiency and reliability of equipment.

VI. Selection and use precautions

1. Selection: When selecting an RV reducer, factors such as the system's load capacity, accuracy requirements, and transmission ratio must be considered. At the same time, it is also necessary to select the appropriate model and specifications according to the specific application scenario.

2. Use precautions:

a. When installing and using the RV reducer, the operation should be strictly in accordance with the requirements of the manual to avoid installation errors or improper use that may cause equipment damage or performance degradation.

b. Regularly maintain and service the RV reducer, check the operating status and lubrication of the equipment, and replace worn parts and add lubricants in a timely manner.

c. Avoid excessive impact and vibration on the RV reducer to avoid affecting its accuracy and life.

d. During use, attention should be paid to abnormal conditions such as temperature and noise of the RV reducer, and timely measures should be taken to deal with them.

In summary, the RV reducer is a high-precision, high-efficiency transmission mechanism that is widely used in industrial robots, machine tools, medical testing equipment, satellite receiving systems, etc. During the selection and use process, it is necessary to make reasonable selections and maintenance according to specific application scenarios and requirements.
