Further, the cylindrical low order end portion of left flange processes for installing supporting planetary frame left bearing step.
Further, left flange and right flange are matched by the hole of seam with the casing left and right sides, and fit system is transition fit.
Further, inner attrition piece is processed with three circular holes near endoporus place, these three circular holes are uniformly distributed along the circumference, three circular holes of all inner attrition pieces align respectively, three guide rods are each passed through three circular holes, and rely on the helical thread portion of left end to be fixed in tapped hole corresponding to left flange, install three groups of belleville springs in the middle of every two panels inner attrition piece, belleville spring is through on guide rod, often organizes 14.
Further, planet carrier left bearing and planet carrier right bearing are selfaligning roller bearing.
Further, belleville spring combination adopts involutory mode.
Further, the internal gear of output shaft and planetary type gear transmission unit is formed in one.
The invention has the beneficial effects as follows: outside friction disc connects for sliding axially with planet carrier, inner attrition piece connects for sliding axially with the spline on left flange, inner attrition piece can only slide and can not rotate, outside friction disc not only slidably but also rotatable, working oil is passed into by working oil entrance during work, namely working oil is full of between outside friction disc in, the viscosity of working oil can stop the rotation of planet carrier, gap in being regulated by in-oil cylinder pressure oil between outside friction disc, just the drag size that outside friction disc bears can be changed, and the rotating speed of planet carrier can change with the drag size suffered by it, so just achieve the rotation speed change of output shaft, control oil cylinder working-pressure oil size according to certain rules, just the output shaft rotating speed changed according to certain rules can be obtained, soft start and speed governing can be realized easily.Its compact structure, easy to adjust, reliable performance, cost are low, has practicability widely.
