A, basic structure
As shown in figure 1, the mechanical winching stepless speed change device mainly comprises a case, a stepless speed change mechanism 1 and a reversing mechanism 2, wherein the stepless speed change mechanism is connected with the reversing mechanism. Wherein,
the stepless speed change mechanism mainly comprises an input shaft 3, an eccentric bearing cam plate 4, a one-way bearing cam plate 6 and a driven shaft 9, wherein one end of the input shaft is connected with the eccentric bearing cam plate, the eccentric bearing cam plate is connected with a transmission connecting plate 5, the transmission connecting plate is connected with the one-way bearing cam plate, and the one-way bearing cam plate is connected with the driven shaft; one end of the C-shaped connecting plate 8 is connected with the eccentric bearing cam plate and the transmission connecting plate, and the other end of the C-shaped connecting plate is connected with the special-shaped speed regulator 7. The eccentric bearing cam plate and the one-way bearing cam plate can be single or multiple.
The reversing mechanism mainly comprises a driving gear 10, a driven gear 11, a sun gear 13, a planet gear 14, a reversing gear 12 and an output shaft 18, wherein the driven shaft is connected with the driving gear, is engaged with the driven gear by the driving gear, or is connected with the driven gear; the driven gear is connected with a sun gear, the sun gear is meshed with a planet gear, the planet gear is meshed with an inner gear drum 16, and the inner gear drum is meshed with one end of an output shaft; the planet wheel is supported by planet carrier 15, and planet carrier connection reversal drum 17, and the gear engagement reversal drum of reversing, shift fork 20 are connected in the gear groove of reversal gear, and reversal drum locking tooth 19 is fixed in quick-witted case 24 (is used for locking the reversal drum).
Second, the working principle
The input shaft of the stepless speed change mechanism rotates to drive the eccentric bearing cam plate to move up and down, and the eccentric bearing cam plate, the transmission connecting plate and the one-way bearing cam plate are connected with each other, so that the transmission connecting plate reciprocates, the one-way bearing cam plate is pushed forwards to idle, the one-way bearing cam plate is pulled backwards to step, and the uninterrupted reciprocating motion forces the driven shaft to generate one-way rotation to drive the driving gear and the driven gear.
The driving chain wheel is rotated to 50 degrees to 60 degrees, the output shaft is at the rotating speed of 0 degree, the shifting fork is shifted, when the reversing gear is at the point A, the reversing gear is meshed with the locking teeth of the reversing drum, the reversing drum is forced to be fixed, and the driven gear, the sun gear, the planet gear, the internal tooth drum and the output shaft obtain reverse output.
When the reversing gear is positioned at the point B, the reversing gear is meshed with the driven gear and separated from the locking teeth of the reversing drum, and the reversing drum rotates integrally to obtain a forward rotation output.
Due to the fact that the eccentric bearing cam plate, the transmission connecting plate and the one-way bearing cam plate are connected with each other, and the special-shaped speed regulator, the C-shaped connecting plate and the eccentric bearing cam plate are connected with each other, the reciprocating motion distance of the transmission connecting plate can be changed by changing the swing angle of the eccentric bearing cam plate, and the rotation angle of the one-way bearing cam plate is forced to change through the motion distance, so that rotation speed adjustment (the speed ratio is 0-12) is achieved. When the rotation speed is adjusted to 0, the rotation speed can be changed in a reverse and forward manner.
The other end of the input shaft is connected with a power source output shaft (a gasoline engine, a diesel engine and a motor, a special-shaped speed regulator is connected with a driven chain wheel, the driven chain wheel 21 is connected with a driving chain wheel 23 through a chain 22, and the other end of the output shaft can be connected with a planetary gear box or a cycloid gear box in order to obtain larger output torque.
