Power disc spins, band dynamic load.
Needle roller and the curved inner surface of shock wave disk cam outer face and permanent tooth are tangent.The processing of shock wave disk inner surface is with teeth,
Its outer surface is double wave cam shape.
The U-lag convenient for needle roller movement is distributed on left force transmiting disk and right force transmiting disk circumference.Needle roller is cased with axis on outer surface
It holds.
Working principle: planet-gear transmission is that seldom inside engaged gear and output mechanism are differed by a pair of of number of teeth
The Planetary Gear Transmission of composition, the present invention are superimposed a kind of gear drive of few teeth difference on the basis of planet Principles of Gear Connection
A kind of NEW TYPE OF COMPOSITE retarder is made in mechanism, i.e., by a shock wave disk, needle roller is driven to be transported along the track designed in advance
It is dynamic, while output block being driven to rotate, the rotating ratio of output block and shock wave cam depends on the number of needle roller in entire retarder
Amount realizes big retarding than, compact-sized purpose in this way by double reduction.
Motor is connected by power input shaft, and then power input shaft is driven to rotate together, and power input shaft rotation is expert at
Shock wave disc spins can be driven in star mechanism, the relationship between the revolving speed of shock wave disk and the revolving speed of power input shaft can be according to planet tooth
The transmission principle of wheel is released；Shock wave disc spins can drive needle roller to rotate along permanent tooth profile, while along left and right force transmiting disk
In tooth socket move up and down, with the rotation of needle roller, left and right force transmiting disk also can and then rotate, band dynamic load.Entire retarder
Reduction ratio is the product of the two reduction ratio.
The utility model has the advantages that compared with prior art, the utility model has the advantage that (1) on the basis of planetary reduction gear
On, it has been superimposed little tooth difference speed reducer, has constituted a composite speed reducer, which has compact-sized, the good, reduction ratio of rigidity
Big advantage；(2) oscillating tooth of little tooth difference speed reducer is in contact with permanent tooth, and load bearing ability is big, is suitable for needing volume
Small, the retarder occasion higher than big, bearing capacity.

Specific embodiment
As shown in Figure 1 and Figure 2, the utility model retarder consists of two parts, and inside is a planetary reducer,
Outside is a little tooth difference speed reducer.Wherein planetary reducer include power input shaft 7, planetary gear 6 and shock wave disk 10,
Shock wave disk end cap 5, few poor tooth retarder include left force transmiting disk 8, right force transmiting disk 4, the force transmiting disk support shaft for supporting left and right force transmiting disk
Hold 9, needle roller 11 and permanent tooth 2, input cover board 1 and output cover board 3.
As shown in Figure 3, Figure 4, shock wave disk 10 is the output wheel of planetary reducer part, and is little tooth difference speed reducer portion
The power input part shock wave device divided, inner surface processing is with teeth, and external surface shape is a double wave cam shape.It is rotating
During, for few teeth difference oscillating tooth, play the role of shock wave device, drives needle roller 11 must be on left force transmiting disk 8 and the right side
It moves up and down, while having to again and table in the curve of the cam outer face of shock wave disk 10 and permanent tooth 2 in the slot of force transmiting disk 4
Face is tangent, integrating as a result, needle roller 11 drives left and right power transmission disc spins, band dynamic load.Wherein left and right force transmiting disk and shock wave disk 10
Rotating ratio and performance, the quantity depending on the shape of 10 cam of shock wave disk, the inner surface profile of permanent tooth 2 and needle roller 11.
As shown in figure 5,7 middle section outer surface of power input shaft processing therein is with teeth, therefore power input shaft 7 is again too
Sun wheel.
As shown in fig. 6, being evenly distributed with "u"-shaped groove on force transmiting disk circumference, it is mainly used for needle roller and is rotated in this slot.Needle roller
Bearing is cased on outer surface, in order to which needle roller is slided and rolled in U-lag.
As shown in fig. 7, the inner surface configuration of permanent tooth is by the quantity of little tooth difference speed reducer needle roller, the wave number and shape of shock wave disk
It is calculated, it is envelope curve formed in needle roller oscillating tooth motion process.
As shown in figure 8, the utility model two end cover plate and shock wave disk end cap have been all made of dual bearing structure, deceleration is improved
The bearing capacity of device.
During the work time, power input shaft 7 is connected to the motor, and after input power generates rotation, driving planetary gear is generated
Rotation, for planetary gear 6 not only with the outer tooth engagement on power input shaft 7, but also the interior tooth engagement with permanent tooth 2, it is existing around itself axis
Rotary motion, and have the rotary motion around retarder axle center, planetary gear rotation drives shock wave disk 10 to rotate, due to shock wave
10 outer surface of disk is a double wave cam surface, and the radius of turn of every bit is different on surface, thus needle roller 11 is driven to do
It moves up and down, while under the action of shock wave disk 11, needle roller 11 does the rotation around retarder axle center along 2 inner surface of permanent tooth,
The rotation of needle roller 11 drives left and right power transmission disc spins, achievees the purpose that with dynamic load.
The reduction ratio of entire retarder is the product of this two parts reduction ratio, when power input shaft input power generates rotation
Afterwards, it drives planetary gear to generate rotation, and shock wave disk inner surface is machined with internal tooth, and therefore, the rotation driving shock wave disk of planetary gear produces
Raw rotation, the reduction ratio between 10 revolving speed of planetary gear shock wave disk and 7 revolving speed of input shaft are(it is assumed that row
Star-wheel does not surround sun gear rotation), wherein z4And z1The respectively number of teeth of the number of teeth of shock wave disk and sun gear.
According to the working principle of little tooth difference speed reducer, for the double wave shock wave disk of the utility model retarder, double wave lacks tooth
The reduction ratio of poor part isWherein z5For the needle roller quantity of little tooth difference speed reducer.Therefore, the reduction ratio of entire retarder
For i=i41×ijg。
