Harmonic Drive servo gear unit FHA-25C-160-E250-C

The following matters should be noted:

(1) Adopt multi-contact zone transmission with splitting and confluence, and adopt unloading structures, such as multi-disc, roller cone flat disc and planetary continuously variable transmission;

(2) Increase the distance between the contact area of the friction pair and the pressure device and the rotation axis as much as possible;

(3) For multi-contact zone transmission, adopt the floating load-sharing structure of the Harmonic Drive flexible gear contact harmonic FHA-25C-160-E250-CK, and strictly control the dimensional deviation and rotation accuracy of a set of rolling elements;

(4) Increase the stiffness of the shafting, limit the length-to-diameter ratio of the shaft extension, and make the transmission and the connected machine be connected in a straight line as much as possible;

(5) When the starting torque is large in use, the starting and braking are frequent, the load changes greatly or there is an impact, electromagnetic clutches, safety clutches or flywheels and other devices should be installed between the transmission and the connected machine;

(6) Adopt an automatic pressure device and reasonably arrange its position and quantity;

(7) Use materials with high elastic modulus and hardness to manufacture the rolling elements. The accuracy of the rolling elements should be above grade G5, and they should be selected and grouped;

(8) Select the appropriate traction oil and lubrication method (oil volume, oil change time and unobstructed flow of the oil circuit, etc.) through tests or experience;

(9) Check the thermal carrying capacity and consider the adoption of a cooling device.

In order to improve the transmission efficiency of the transmission and reduce sliding and wear, attention should be paid to:

(1) Strive to make the equivalent cones of the friction pair at any speed regulation position of the Harmonic Drive flexible gear contact harmonic FHA-25C-160-E250-CK be able to have a common vertex, or the two cone vertices are on the same side of the contact area and are as close as possible to improve the parallelism accuracy of the two parallel axes;

(2) Under the condition of meeting the strength requirements, reduce the contact width or adopt a point contact structure
