The retarder of embodiment as shown in Figure 1 includes the first face gear 1, the second face gear 2,3 and of cylindrical planetary gear
Planet carrier 4.First face gear 1 is used to be drivingly connected with power input 9；Second face gear 2 is coaxial with the first face gear 1 and tooth
Number is different, and the flank of tooth of the second face gear 2 is opposite with the flank of tooth of the first face gear 1, and the second face gear when the rotation of the first face gear 1
2 rotate relative to the first face gear 1；Cylindrical planetary gear 3 is meshed with the first face gear 1 and the second face gear 2；Planet carrier 4
Cooperate with cylindrical planetary gear 3, for rotating under the drive of cylindrical planetary gear 3 around the axis of the first face gear 1 with downward
Revolving speed and torque after level-one mechanism output deceleration torque increase.
In retarder work, the first being rotated by power input 9 of face gear 1 be can have defeated with power
Enter the identical revolving speed w1 of part 9.The revolving speed of second face gear 2 is w2, and the second face gear 2 can pass through centre as shown in figures 1 and 3
Transmission mechanism 5 and power input 9 are drivingly connected, and the second face gear 2 is led under the driving of power input 9 when retarder works
It crosses intermediate transmission mechanism 5 and obtains the revolving speed different from the first face gear 1.
In some unshowned embodiments of diagram, the second face gear 2 can also be remain stationary, not by power input 9
Driving, such as the second face gear 2 keep relatively fixed with reducer shell, thus the second face gear 2 in retarder work
Revolving speed w2 is 0, different from the revolving speed of the first face gear 1.
In retarder work, the first face gear 1 and the second installation, the i.e. belt wheel of the first face gear 1 face-to-face of face gear 2
The end face of tooth is opposite with the end face of 2 pulley teeth of the second face gear；First face gear 1 and the second face gear 2 have teeth number difference.Cylinder
Planetary gear 3 is clipped among the first face gear 1 and the second face gear 2, is engaged respectively with the first face gear 1 and the second face gear 2,
Cylindrical planetary gear 3 can have 1 or multiple, and planet carrier 4 can be the various shapes such as crankshaft shape, housing shape.As shown in Figure 1
Planet carrier 4 be housing shape, the gear shaft 31 of multiple cylindrical planetary gears 3 is located in the mounting hole 41 of planet carrier 4.In retarder
When work, work of the cylindrical planetary gear 3 in the first face gear 1 and the second face gear 2 with rotational speed difference and with teeth number difference
With lower rotation and revolution, drives planet carrier 4 to rotate by revolution, pass through the outside output torque of planet carrier 4 and revolving speed.
If revolving speed of the planet carrier 4 when retarder works is wx, then the characteristic equation of the retarder of the present embodiment are as follows:
W1- (1+a) wx+aw2=0 ... (1)
A=z2/z1=(z1-k)/z1 (k ≠ 0) ... (2)
Transmission ratio: i=w1/wx ... (3)
Wherein, z1 is the number of teeth of the first face gear 1, and z2 is the number of teeth of the second face gear 2, and a is the second face gear 2 and first
The gear ratio of face gear 1, k are the teeth number difference of the first face gear 1 and the second face gear 2.
According to formula (1), formula (2) and formula (3), by the different number of teeth z1 of the first face gear 1 of setting and the second face gear 2,
Z2, and make the first face gear 1 and the second face gear 2 that there is different revolving speed w1 by the way that different intermediate transmission mechanisms 5 is arranged
And w2, available different transmission ratio i.
When intermediate transmission mechanism 5 is equal revolving speeds reversing mechanism, wait revolving speeds reversing mechanism make the revolving speed of the first face gear 1 with
The revolving speed size of first face gear 1 is identical, contrary.That is the second face gear 2, which passes through, waits revolving speeds reversing mechanism and power to input
Part 9 connects, and the second face gear 2, which passes through, waits revolving speeds reversing mechanism to obtain revolving speed w2=-w1 under the driving of power input 9.
According to formula (1), formula (2) and formula (3), the transmission ratio of retarder at this time:
I=(1+a)/(1-a)=2/ (1-a) -1
That is, (4) i=2z1/k-1 ... at this time
According to formula (4), when the second face gear 2 and the first face gear 1 are few teeth difference feature, i.e. k > 0, and k is smaller, slow down
Device can obtain big transmission ratio.When 2 to the first face gear 1 of the second face gear lacks 1 tooth, i.e. k=1, retarder can be obtained
Transmission ratio i=2z1-1.It is easier to obtain bigger transmission ratio compared to traditional small teeth difference planetary mechanism, namely same
Under the requirement of transmission ratio, the retarder of the present embodiment may be implemented smaller, and structure is more compact.
Face gear transmission is a kind of unparallel shaft gear-driven form for being different from Bevel Gear Transmission, and face gear transmission passes through
Roller gear is meshed with face gear carries out gear drive.The retarder of the present embodiment, by designing the first face gear 1 and second
The different teeth difference of face gear 2 and different rotational speed differences, realize the deceleration torque increase under different drive ratios in which can be convenient.Pass through conjunction
The teeth number difference and rotational speed difference of the design of reason ground the first face gear 1 and the second face gear 2, can also make retarder have biggish transmission
Than to meet the occasion for needing large transmission ratio.In addition, the installation of cylindrical planetary gear 3 or work of the present embodiment retarder exist
When generating displacement error on its axis direction, since cylindrical planetary gear 3 and the cooperation of the first face gear 1 and the second face gear 2 pass
Graduating power, the vertex of a cone of not traditional Bevel Gear Transmission, which is overlapped, to be required, it is possible to reduce planetary gear axis direction generates mobile miss
To the influence of transmission when poor, design easier for installation simple.In addition, the present embodiment retarder due to using face gear be driven,
Registration is big, and transmission ratio fluctuation is small.When cylindrical planetary gear 3 is straight spur gear, without axial force on cylindrical planetary gear 3
Effect keeps the structure of retarder more simple and compact so as to simplify support.In addition, the retarder of the present embodiment is adopted
With the face-to-face near symmetrical mounting arrangements form of two face gears, it can realize that the error in power transmission process is mutual at work
There is back lash in transmission in compensation, such as the first face gear 1 and the second face gear 2, since the two is approximate right face-to-face
The arrangement of title, influence of the back lash of the two to transmission accuracy, can compensating for coupling to a certain extent, to improve deceleration
