正因为这两点作用而使得行星减速机被广泛应用,倍受各行各业青睐。 The main role of the planetary reducer is to reduce the speed of the motor and increase the torque. Because of these two points, the stepping planetary reducer in Shandong has been widely used and is favored by all walks of life. But many bosses and purchasers are not very clear about what planetary reducers are classified by.


减速机怎么分类

How to classify the reducer

First, classify according to the size of power. The planetary reducer is divided into power and low power according to the power. These two categories have different properties and can be used on different mechanical equipment.

Second, classify according to the arrangement of gears. Planetary reducers can be divided into spur gears and helical gears according to the arrangement of the gears. Spur gear planetary reducers are cost-effective and are generally used in mechanical equipment with low load and unidirectional running speed. The helical planetary reducer is more expensive than the spur planetary reducer, but the helical planetary reducer has low noise, high accuracy, smooth operation, and high manufacturing process requirements, which is why the price is higher than the spur planetary reducer.

Third, classify according to the angle of the input shaft and the output shaft. The planetary reducer can be divided into right-angle planetary reducer and parallel-axis planetary reducer according to the input shaft and output shaft. The parallel-axis planetary reducer's input shaft is parallel to the output shaft at 180 degrees. The input shaft and output shaft of the right-angle planetary reducer are at right angles, at 90 degrees, which can realize 360-degree installation without dead angles, which is more widely applicable.

Fourth, the planets are classified according to the support method of the planet carrier. The planetary reducer can be divided into single support and double support according to the support method of the planet carrier. The performance of the dual support is much better than the single support, but because of the high manufacturing process requirements, the double support is much more expensive than the single support. In addition, the helical planetary reducers are all double-supported structures, and the spur gear planetary reducers can adopt both single-and double-supported structures.

How to calculate the torque of a planetary reducer

已广泛应用于中国工业的各个领域。 At present, stepping planetary reducers have been widely used in various fields of Chinese industry. The magnitude of the planetary reducer's torque determines the application field and scope of the planetary reducer. The common calculation formulas of the planetary reducer's torque, the output torque and speed of the low-power planetary reducer are introduced in some specifications. So how to calculate the torque of the planetary reducer?

The torque of the planetary reducer is determined by the power speed. The rated output (input) torque of the reducer is determined by the rated transmission power and rated output (input) speed of the reducer. The actual output (input) torque is determined by the actual transmitted power (load size) and actual output (input) speed of the reducer. . Choose the most suitable reducer model and specification to ensure the safety of the product and not to overload it. If the rated output torque of the reducer is insufficient and the working machine cannot move, you can only replace the reducer and choose a reducer with a larger rated power or a reducer with a constant rated power and a small output speed.

Reverse calculation:

For the service life of the servo reducer, the calculation of torque is very important. Pay attention to whether the maximum torque value (TP) of the acceleration exceeds the maximum load torque of the reducer.

Reduction ratio = speed of servo motor / speed of output shaft of reducer

The applicable power is usually the applicable power of servo motors on the market. The applicability of the reducer is very high, and the working coefficient can be maintained above 1.2. However, you can also choose according to your needs:

There are two main points:

The output shaft diameter of the servo reducer should not be larger than the maximum shaft diameter used in the table.

If the torque calculation is successful, the speed can meet normal operation. However, when the servo output is full and insufficient, we can perform current limiting control in the driver on the motor side or torque protection on the mechanical shaft, which is very necessary.

的转矩?就是这样。 How to calculate the torque of Shandong stepping planetary reducer ? That's it. The planetary reducer is a new type of reducer with a wide range of applications, with a maximum input power of 104kW.
