Does the servo planetary reducer have the function of braking?

Does the servo planetary reducer have the function of braking? In fact, the Bagman planetary reducer does not have the function of braking, it is through the large and small gears in the planetary motion mode to achieve the effect of deceleration, through the drive device to move. The function of braking is completed in the following two ways:

Brakes are mounted on the motor and output shaft equipped with braking.

Servo motors can be equipped with brakes. Our company has it.

The function of the servo motor is to perform servo, i.e. precise positioning. The output speed and torque of the motor of the reducer are adjusted to meet the needs. Because the speed output of the motor is usually constant (just a few gears), and the actual required speed varies greatly, it is necessary to use the reducer to adjust to the required speed range.

When the load of the servo motor is very large, blindly increasing the power of the servo motor to meet the required torque will cause a waste of cost. Therefore, it is reasonable to choose a servo reducer with a reduction ratio within the required speed range. The role of the servo reducer itself is to slow down the speed and increase the output torque.

The speed of the servo motor generally cannot meet the requirements of low speed and high torque of the workload, which is described in a popular sentence: the servo motor and the reducer are twins.

The reducer is matched with the motor to reduce the speed and increase the torque. It does not have a braking function per se.

1. This is to increase the torque, and the way to increase the output torque may be to directly increase the output torque of the servo motor;

2. However, this method not only requires the use of expensive and high-power servo motors, but also has a stronger structure, and the increase of torque is proportional to the increase of control current;

3. At this time, the use of relatively large drivers, the increase of power electronic components and related mechanical and electrical equipment specifications, will greatly increase the cost of the control system.

Bapman planetary reducer experts summarized the connection method between the servo motor and the servo planetary reducer, there are two main methods:

When the reducer mechanism is made, there will be an input end to install the flange according to the customer's servo motor, and the motor shaft will be inserted into the input locking ring of the reducer, and it will be locked with bolts through the side flange opening.

Theoretically, there is no loss of energy at the time of conversion, but in practice there is. Therefore, the efficiency of the planetary reducer is generally 95-97%, and the output torque is somewhat lost from the ideal. For example, a 400w servo motor, with a reduction ratio of 10, should be magnified ten times when the theory comes out.

However, when your motor is running, it will be hot, and the temperature rise will also follow the reducer. Therefore, a certain amount of torque space will be reserved when selecting the model. In this space of the earth, energy and matter are not conserved.

The main transmission structure of the planetary reducer is composed of the sun gear, the planetary gear and the gear ring. The planetary reducer has the advantages of small size, large torque, small moment of inertia, small backlash, high precision, high efficiency, low noise, long life, maintenance-free, and can be installed at will.

Suitable for all grades of servo motors and stepper motors.

The function of the servo motor is to realize the servo, that is, precise positioning. The output speed and torque of the planetary reducer can be adjusted as needed. Since the speed output of the motor is usually constant, the actual required speed varies greatly, so the planetary reducer needs to be adjusted to the required speed range.

The planetary reducer transmission has the advantages of small size, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency, large transmission ratio range, stable operation, low noise, strong adaptability and safe performance. It has the characteristics of power shunt and multi-tooth meshing.

Planetary reducer has advantages compared with other reducers!

The three basic functions of the planetary reducer in servo control:

1. Reduce the speed of the servo motor.

The quota power of the servo motor is generally reflected in the speed between 1000rpm and 6000rpm, or even up to more than 10000rpm, and such a high speed is rarely used in the actual use process.

2. Torque amplification.

In the case that the power input of the motor to the reducer is constant, due to the decrease of the output speed of the reducer, a large output torque will inevitably be generated. In many cases, this is an important reason why Bapmann Industrial Technology chose planetary gear units.

3. Match the moment of inertia of the load.

In general, the inertia of the servo motor is small, generally speaking, the load inertia converted into the servo motor itself can not exceed 4 times of the inertia of the servo motor itself (the design of different brands of servo motors has very specific data), and there are many kinds of loads in practical applications, if the inertia of the load is too different from the acceptable inertia of the motor, it will greatly reduce the response speed of the servo motor, thereby affecting the production efficiency and increasing the dynamic error. At the same time, planetary gearboxes can also play a key role in inertia matching.

The size of the Buckman servo planetary gearbox depends mainly on the performance requirements:

Speed - How fast does the application need the output shaft to turn?

What are the torque-torque load requirements?

Cantilever Loads - External radial loads applied to the output shaft may require greater gear load capacity and therefore larger gears.

Shutdown - How long does the servo planetary gearbox run before it shuts down? Depending on the service life requirements, smaller gearboxes can be used for intermittent load applications.

Lifespan - How many cycles or hours of continuous hours does it take to meet the required life? Compared with the design of 4000 hours, the design of 400 small wood mold time is very different in the size of the yard pure size.

1. Increase the speed ratio, increase the speed ratio on the servo planetary reducer, which can effectively improve the bearing requirements of the servo planetary reducer in use.

2. When choosing a servo planetary reducer, it is better to choose a better gear for the first type.

3. Increase the tooth width, and appropriately increase the width of the servo planetary reducer gear under the condition that the outer diameter size remains unchanged, which can effectively improve its bearing capacity.

4. The contact stress of the ring gear is the most likely to fail, so if it is necessary to increase the bearing capacity, it is necessary to ensure the contact stress of the ring gear.
