Performance characteristics:

1. MB transmission speed control precision, speed control precision in 0.5-1 turn, which is the leader of similar products.

2. The height range is large and the speed regulation range is RB = 5.

3. All transmission parts of this series of transmission have been strictly treated, precision processed, ground, good contact and lubrication performance, so it runs smoothly, with low noise and long service life.

4. The most important feature of MB transmission is that it can effectively be used as a combination of various gear reducers, cycloid reducers, worm gear reducers and reduction motors, so as to increase the output torque and realize the minimum and maximum output speed of various field platforms, which has good adaptability.

5. The output torque and power of MB transmission change with the change of output revolutions. With variable torque, variable power mechanical characteristics

summary:

MB planetary friction continuously variable transmission is mainly composed of driving wheel device, friction transmission mechanism and speed control mechanism. It is a kind of transmission widely used at present. In foreign countries, Italy, Germany, Japan, Britain and other countries have production.

Working principle:

The driving wheel (12) with taper and the pressure plate (13) are compressed by a set of disc springs (14), and the input shaft (15) and the driving wheel are connected by a flat key to form a compressed driving wheel device.

The inner side of a group of planetary friction wheels (10) with taper is clamped between the active transmission line and the pressure plate, and the outer side is clamped between the fixed ring (11) with taper and the speed regulating cam (9) to form a pair of friction wheels. When the pressed driving gear device is running, the planetary friction wheel will make pure rolling, because the fixed ring and speed regulating cam will not move. Therefore, the planetary gear will also make revolution when it rotates, and drive the planetary carrier (2) to rotate through the central shaft of the planetary friction wheel and the sliding block bearing (5).

When the hand wheel is turned to change the angular position, the end curve of the speed regulating cam acts through the end curve of the plane bearing (4) and the fixed plane cam (3), which makes the speed regulating cam move axially, so as to change the clearance between the fixed rings of the speed regulating cam at a constant speed, and make the planetary friction wheel move radially, so as to change the planetary gear and the driving wheel, the pressure plate and the fixed ring By adjusting the working radius of the friction part of the cam, the CVT is realized stably.

2、 Performance characteristics

1. High strength: in the case of impact load or machine reversal, the machine has reliable performance and can drive accurately without rear seat force.

2. Wide speed range: the speed ratio is 1:5, that is, the output speed can vary from 1:45 to 1:7.25.

3. High speed regulation precision: speed regulation precision is 1-0.5 rpm.

4. Stable performance: the transmission parts of the machine have undergone special heat treatment, precision processing of friction parts, good lubrication, stable operation, low noise

Long life.

5. Coaxial structure: input shaft and output shaft rotate in the same direction, small volume and light weight.

6. Strong combination ability: This machine can be combined with various types of reducers to achieve the effect of low speed and high torque.

7. Under the condition of allowable load, the set speed is constant.

8. It can be used in humid, dusty and slightly corrosive working environment.

5、 Display of output speed

1. Speed handwheel: directly can not see the speed.

2. Pointer hand wheel: the speed displayed on the pointer deviates from the actual output shaft speed by 3-5 ° turns

3. Digital tachometer: the display speed is completely consistent with the actual output speed.

6、 Working humidity

The temperature rise can be 40 ° to 50 ° higher than the ambient temperature at the beginning of component friction (empty machine operation), and the temperature gradually decreases after 60-80 hours of operation. The temperature is about 25 ° higher than the ambient temperature and remains constant.

Note: it is normal to raise the temperature by 10 ° to 20 ° when using two-stage motor.
