State the input shaft of Multi-stage speed-changing drive mechanism.The sleeve and leading portion jackshaft are connected to form a whole by flat key, are constituted
Eccentric stiffener 24 among leading portion.Realize leading portion front gear 21 and leading portion intermediate gear 22 and leading portion in two eccentric directions, one position
The connection of backgear 23, another position are realized among the leading portion front gear 21 ', leading portion backgear 23 ' and leading portion of different parameters
The connection of gear 22 can match the leading portion front gear 21 ' of replacement, parameter and the intermediate gear of leading portion backgear 23 ' engage ginseng
Number matching.Leading portion space 25 provides installation space when pairing replacement.Leading portion jackshaft shaft end portion is axial by vertical flat key
It positions and fixes in the housing, the entire component of eccentric stiffener need not be replaced among such leading portion;As long as replacing leading portion front gear
Speed change can be realized with leading portion backgear.
In addition, the preceding section speed change mechanism can be replaced with the leading portion front gear of different reduction ratio with the whole series replacement
21 ', leading portion intermediate gear 22 ', leading portion centre eccentric stiffener 24 ' and leading portion backgear 23 '.It is related to the leading portion on the shell
The positioning of gear and connection structure keep interchangeability.
The replacement of eccentric stiffener 24 ' can also only replace a part, such as reduction ratio bigger in order to obtain among leading portion,
Eccentric bigger sleeve can be replaced, and the other assemblies of eccentric stiffener can be general among leading portion, then before cooperating replacement leading portion
Gear and leading portion backgear realize speed change.
It can be seen that by partly or entirely replacing the preceding section speed change mechanism, it can be the case where other parts remain unchanged
Under, different revolving speeds and different power outputs are obtained at roller.
As shown in Figure 1, the Multi-stage speed-changing drive mechanism can also include middle section speed change mechanism 3, the middle variator
Structure includes the middle section front gear 31 and middle section backgear 32 being meshed, middle section front gear and middle section backgear respectively with middle section front axle
