In another alternative embodiment of the present application, the product of the number of teeth of the fixed gear 10 and the number of teeth of the second transmission gear 13 may be a first product; the product of the number of teeth of the first transmission gear 12 and the number of teeth of the output gear 11 may be a second product; the ratio of the second product to the first product may be a preset value.
In practical applications, by setting a specific ratio of the second product to the first product, a more flexible rotation speed ratio between the output gear 12 and the planet carrier 14 is achieved.
An example of a rotational speed calculation process for the transmission shown in fig. 2 is provided below:
in the transmission shown in fig. 2, the number of teeth of the fixed gear 10, the first transmission gear 12, the second transmission gear 13 and the output gear 11 can be respectively Z1、Z2、Z3、Z4It is shown that the radii of the fixed gear 10, the first transmission gear 12, the second transmission gear 13 and the output gear 11 can be respectively represented by R1、R2、R3、R4The angular velocities of fixed gear 10, output gear 11, and carrier 14, respectively, may be represented by ω1、ω4、ωHIndicating that the common angular velocity of said transmission is represented by- ωHAnd (4) showing.
Since the fixed gear 10 is fixedly connected to the first rotation shaft 15, the fixed gear 10 does not rotate, i.e., the fixed gear 10 does not rotate
ω1＝0 (1)
The speed of rotation of fixed gear 10 relative to planet carrier 14
Can be expressed as:
rotational speed of output gear 11 relative to carrier 14
Can be expressed as:
ratio of the rotation speed of the fixed gear 10 to the rotation speed of the output gear 11 relative to the carrier
Can be as follows:
in the embodiment of the present application, since the first transmission gear 12 is engaged with the fixed gear 10, the second transmission gear 13 is engaged with the output gear 11, the fixed gear 10 is coaxially disposed with the output gear 11, and the first transmission gear 12 is coaxially disposed with the second transmission gear 13, the sum of the radius of the first transmission gear 12 and the radius of the fixed gear 10 is equal to the sum of the radius of the second transmission gear 13 and the radius of the output gear 11.
R1+R2＝R3+R4(5)
Because the involute gear needs to satisfy:
Z1·m＝π·R1，Z2·m＝π·R2，Z3·m＝π·R3，Z4·m＝π·R4(6)
substituting the formula (6) into the formula (5) to obtain the final product
Z1+Z2＝Z3+Z4(7)
In practical applications, the ratio of the second product to the first product may be set on the premise that equation (7) is satisfied
Specific values of (a).
Specifically, substituting the specific value into equation (4), the rotation speed ratio of output gear 12 and carrier 14 can be set.
In a preferred embodiment of the present application, in order to allow the output gear 12 and the carrier 14 to output the reverse rotation at a constant speed, the ratio of the second product to the first product may be 1: 2. That is to say that
Substituting the formula (8) into the formula (4) to obtain the final product
ω4＝-ωH(9)
In the examples of this application, when Z is1、Z2、Z3、Z4On the premise of simultaneously satisfying the formula (7) and the formula (8), the output gear 12 and the planet carrier 14 can output constant-speed reverse rotationAnd (7) turning.
In practice, if the transmission is used to output constant speed reverse motion, then Z is caused to be1、Z2、Z3、Z4And simultaneously satisfying the formula (7) and the formula (8).
For example, in Z1＝Z2When the value is 30, Z can be obtained by substituting the data into the equations (7) and (8)3＝40，Z4In this case, the transmission can be used to output a constant speed reverse motion 20.
Of course, in practical applications, the ratio of the second product to the first product may also be set to other values, so that the output gear 12 and the planet carrier 14 output the reverse motions at different rotation speeds, and the embodiment of the present application does not specifically limit the ratio of the second product to the first product.
In an embodiment of the present application, the transmission device may further include: a drive member that may be connected with the output gear 11 or the planet carrier 14 to power the transmission such that the output gear 11 and the planet carrier 14 output opposite rotational motions.
An example of the operation of the transmission shown in fig. 2 is provided below:
in this working example, the output gear 11 is connected to the drive member of the transmission.
In the case where the output gear 11 rotates in the clockwise direction, the second transmission gear 13 may generate rotation in the counterclockwise direction due to the engagement between the output gear 11 and the second transmission gear 13. Specifically, the change in the position of the output gear 11 may refer to the change in the trajectory of the hole a on the output gear 11, and similarly, the change in the position of the second transmission gear 13 may refer to the change in the trajectory of the hole B on the second transmission gear 13. Due to the coaxial arrangement of the first transmission gear 12 and the second transmission gear 13, in the case that the second transmission gear 13 rotates in the counterclockwise direction, the first transmission gear 12 will also correspondingly rotate in the counterclockwise direction, and by the engagement between the first transmission gear 12 and the fixed gear 10, the counterclockwise rotation of the first transmission gear 12 and the second transmission gear 13 can be further pushed.
Because one end of the planet carrier 14 is coaxially arranged with the fixed gear 10 and the output gear 11, and the other end is coaxially arranged with the first transmission gear 12 and the second transmission gear 13, the planet carrier 14 correspondingly rotates counterclockwise in the process of counterclockwise rotating the first transmission gear 12 and the second transmission gear 13.
In the process that the output gear 11 rotates in the clockwise direction and the planet carrier 14 rotates in the counterclockwise direction, the first transmission gear 12 and the second transmission gear 13 can sequentially pass through the second position shown in fig. 3 and the third position shown in fig. 4. Thus, the second transmission gear 12 meshes with the output gear 11 by meshing the first transmission gear 12 with the fixed gear 10, and the reverse rotation of the carrier 14 and the output gear 11 is realized.
By analogy, under the condition that the output gear 11 rotates in the counterclockwise direction, the planet carrier 14 may rotate in the clockwise direction, and the specific process is referred to the above process, which is not described herein again.

Since the first transmission gear 12 is meshed with the fixed gear 10, and the second transmission gear 13 is meshed with the output gear 11, in the process that the first transmission gear 12 and the second transmission gear 13 rotate anticlockwise, the output gear 11 can be driven to rotate clockwise through the meshing of the second transmission gear 13 with the output gear 11 and the meshing of the first transmission gear 12 with the fixed gear 10.
In the process that the planet carrier 14 rotates in the counterclockwise direction and the output gear 11 rotates in the clockwise direction, the first transmission gear 12 and the second transmission gear 13 can sequentially pass through the second position shown in fig. 3 and the third position shown in fig. 4. Thus, the second transmission gear 12 meshes with the output gear 11 by meshing the first transmission gear 12 with the fixed gear 10, and the reverse rotation of the carrier 14 and the output gear 11 is realized.
By analogy, under the condition that the planet carrier 14 rotates clockwise, the output gear 11 can rotate counterclockwise, and the specific process is only referred to the above process, which is not described herein again.
As can be seen from the two working process examples, in the embodiment of the present application, the output gear 11 and the planet carrier 14 can output reverse rotational motions whether the driving component of the transmission is connected with the output gear 11 or the planet carrier 14.
As can be seen from the above, the embodiment of the present application provides a transmission device, which has at least the following advantages:
