Transmission of csD-40-160-2UF motion in Hamenaco precision range harmonic module. Harmonic drive is usually composed of three basic components, including a rigid wheel with inner teeth, a flexible wheel with outer teeth that can produce radial elastic deformation when working, and a wave generator installed in the flexible wheel internal transmission part wave, oval shape, with flexible rolling bearings in the outer ring. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
And, more importantly, in the precision gear transmission, it can effectively reduce the return, such as in the servo mechanical structure, for the reduction of the total return of the chain of the last gear pair, sometimes the use of adjustable center distance structure. However, it should be noted that the backlash between the adjustable towel center and the gear pair cannot be completely eliminated. The precision range transmission harmonic module CSD-40-160-2UF can reduce the influence of the following factors on the backlash of the gear pair compared with the gear pair whose center distance is not adjustable: center distance error. * Feed error
The above analysis of two kinds of errors affecting the transmission accuracy, a total of four factors, of which the intrinsic tangential comprehensive error of a single gear has the greatest impact on the one-way transmission error, assembly eccentricity caused by one-way transmission error, sometimes can be ignored. Other errors, such as the drift of the shaft in the bearing and the ball bearing in the oversize box hole, etc., can be ignored because these are more difficult to predict.
In the analysis of the error and the one-way transmission error, they have both difference and mutual, such as the cutting error (tooth thickness thinning) has an effect on the return error, and for the simple transmission error qiang Qinxiang, hanging eccentric error has no effect on the return error. Hamenaco precision range-transmitting harmonic module CSD-40-160-2UF has influence on one-way transmission error; The installation of the core deviation has an effect on the return error, and for the one-way movement of the amplitude variation, when the force is more stable.
The calculation of torque of precision gear transmission chain is divided into the calculation of torque value in the working state of the transmission chain and the calculation of torque value in the assembly state of the transmission chain. The former is used to select csD-40-160-2UF, check the power of the servo motor, and correctly design each link of the mechanism from the point of view of strength and stiffness.
