Introduction oｆ the filter drive mechanism

For a long time, drive motor and reducer in the mechanical equipment are designed separately, so inevitablyit needs to consider the connection design between them.

Using connection equipments, such as splines, coupling ,etc, makes structure more complicated, increases quantity and variety of components, decreases system reliability, expands the volume and weight, causes errors in axis, abrades transmission mechanism, and blocks the running of the mechanism. On the other hand, the thermal deformation and thermal stress of precise bearings and gear pairs under the large temperature differences condition will easily cause problems, like the lubrication failure,meshing interference and jamming,etc. Furthermore, under external mechanical vibration and impact excitation environment the traditional rigid gear transmission vice easily causethe reliability problems of vibration noise, structural damage by the response.

Aiming at the problemsabove, Chongqing BTG technologycompany have designed filter drive mechanism with filterreducer components and servo motor, sensor integration through participate in the key project of national natural science foundation, national defense projects more than 10 research projects.It combined with intelligent control method to compensate power transmission in the process of transmission error, nonlinear uncertain factors such as friction, elastic deformation, which can achieve high precision, good response characteristic andgood robustness servo positioning. The product has the advantages of high precision, high rigidity, high reliability, long life, high torque, low energy consumption, small volume, lightweight, low noise, it has been granted a state authorized invention patent (patent no. ZL200910104672.6), applied in aviation, aerospace, industrial robots, and other areas of the high-end equipment.

Product feature:

1)      Miniaturization, high torque characteristics

Under the condition of the same output torque,compared with single motor, actuators can realize small lightweight; under the same overall dimensions conditions, executive element to realize high torque, which can provide actuators of cylinder and flat hollow.

2)      High stiffness characteristics(not easily affected by the change of load)

Angle transmission error of driving mechanism of the gear reducer is small, with high rigid gear reducer to determine the influence of load change, therefore, even if there is load fluctuations, drive mechanism also can undertake very stable positioning of small errors (high stiffness characteristics).

3)Positioning short time (even if the moment of inertia change, it also can undertake stability control)

Comparing single motor, drive mechanism in a short time of output shaft inertia is larger and numerical changes during the process of operation, drive mechanism can be stable and controlled, the shorter positioning can be obtained.

Guide for Selection

According to the load situation, condition coefficient to determine the output torque, reduction ratio, speed and power output, appearance size, please contact chongqing BTG technology company, the company can be customized production according to user requirements.
