Description
Technical field
The present invention relates to a kind of cycloidal planetary gear speed reducer, belongs to gear reducer component technical field.
Background technology
Gear reducer plays a part of to match rotating speed between prime mover and working machine or executing agency and transmits torque, gear reducer
It is a kind of relatively accurate machinery, the purpose using it is to reduce rotating speed, increases torque；It can be divided into list according to transmission series difference
Level and multistage speed reducer；It can be divided into cylindrical gear reducer, conical gear reducer and circular cone, Cylinder Gear according to tooth factory wheel shape
Running wheel gear reducer；Arrangement form according to transmission can be divided into expansion, shunting and with into shaft type gear reducer again；Retarder is one
Kind is driven formed individual components by the gear drive, worm-drive, pinion-endless screw being enclosed in stiff case, is commonly used for
Speed reduction gearing between driving link and working machine；Matching rotating speed and biography are played between prime mover and working machine or executing agency
The effect of torque is passed, using extremely wide in modern mechanical.Gear reducer is generally used for the drive apparatus of low rotation speed large torque,
The few gear engagement output shaft of the number of teeth on input shaft that motor, internal combustion engine or other power to run at high speed pass through gear reducer
On gear wheel achieve the purpose that deceleration, common gear reducer, which also has, several reaches same principle gear effect of preferably slowing down
The ratio between fruit, the number of teeth of big pinion gear, is exactly gearratio.Existing gear reducer service life is shorter, it is necessary to often carry out maintenance, and
Oscillation Amplitude is big when gear reducer works, and the noise of generation is larger.
The content of the invention
To solve the above problems, the present invention proposes a kind of cycloidal planetary gear speed reducer, and it is compact-sized, it is small；Make
With reliable, durable long lifespan；Vibration and noise is set to be limited in minimum degree, smooth running noise is low；Design is reasonable, maintenance
It is convenient.
The cycloidal planetary gear speed reducer of the present invention, including pin wheel housing；Pin gear is installed in the pin wheel housing；The pin
The pin gear of gear one group of annular array thereon is engaged with two Cycloidal Wheels；Pivoted arm is provided among the Cycloidal Wheel；The pivoted arm
End is connected with input shaft；The Cycloidal Wheel rear end is provided with output shaft away from pivoted arm side by W output mechanisms.
As preferred embodiment, the double eccentric sleeves of 180 ° of a dislocation are installed on the input shaft；The eccentric bushing
It is upper that two roller bearings are housed, form H mechanisms.
As preferred embodiment, pin gear sleeve is carried on the pin gear, reduces friction.
As preferred embodiment, the input shaft and output shaft are located at same axle center.
Compared with prior art, cycloidal planetary gear speed reducer of the invention, employs Gear Planet Transmission principle to the present invention,
Input shaft and output shaft are compact-sized on same axle center, small；Major part uses bearing steel, and quenched processing obtains high
Intensity, and driving contact employs rolling friction, uses reliable, durable long lifespan；Cycloidal pin teeth total number of teeth in engagement is more,
Overlap coefficient is big and has the stable mechanism of parts, vibration and noise is limited in minimum degree, smooth running noise is low；If
Meter is reasonable, easy to maintenance, easily decomposes installation, minimum parts count and simple lubrication, runs cycloidal planetary gear speed reducer
Reliably.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Each component is labeled as in attached drawing：1- pin wheel housings, 2- pin gears, 3- Cycloidal Wheels, 4- pivoted arms, 5- input shafts, it is defeated that 6- crosses W
Go out mechanism, 7- output shafts.
Embodiment
As shown in Figure 1, the cycloidal planetary gear speed reducer of the present invention, including pin wheel housing 1；It is provided with the pin wheel housing 1
Pin gear 2；The pin gear of the pin gear 2 one group of annular array thereon is engaged with two Cycloidal Wheels 3；Set among the Cycloidal Wheel 3
It is equipped with pivoted arm 4；4 end of pivoted arm is connected with input shaft 5；4 rear end of Cycloidal Wheel exports machine away from 4 side of pivoted arm by W
Structure 6 is provided with output shaft 7.
The double eccentric sleeves of 180 ° of one dislocation are installed on the input shaft 5（It is not shown）；Equipped with two rollings on the eccentric bushing
Axis of a cylinder is held, and forms H mechanisms.
Pin gear sleeve is carried on the pin gear 2（It is not shown）, reduce friction.
The input shaft 5 and output shaft 7 are located at same axle center.
The cycloidal planetary gear speed reducer of the present invention, the double eccentric sleeves equipped with 180 ° of a dislocation on input shaft, inclined
The heart is put on equipped with two roller bearings, forms H mechanisms, the centre bore of two Cycloidal Wheels is the rolling of rotary arm bearing on eccentric bushing
Road, and be meshed by Cycloidal Wheel with the pin gear of one group of annular array on pin gear, to form few teeth difference internal messing reducing gear,
In order to reduce friction, in speed than in small gear reducer, pin gear sleeve is carried on pin tooth；When input shaft rotates one week with eccentric bushing
When, due to being limited the tooth corridor curve in Cycloidal Wheel the characteristics of and its by pin gear upper pin gear, the movement of Cycloidal Wheel becomes i.e.
There is revolution and have the plane motion of rotation, when input shaft just circles, eccentric bushing also rotates one week, and Cycloidal Wheel is in opposite direction
On turn over tooth difference so as to be slowed down, then by W output mechanism, the low speed spinning motion of Cycloidal Wheel is passed through into axis pin, is passed
Output shaft is passed, so as to obtain relatively low output speed；Gear Planet Transmission principle is employed, input shaft is with output shaft in same axle center
It is upper compact-sized, it is small；Major part uses bearing steel, and quenched processing obtains high intensity, and driving contact employs
Rolling friction, uses reliable, durable long lifespan；Cycloidal pin teeth total number of teeth in engagement is more, and overlap coefficient is big and has parts
Stable mechanism, makes vibration and noise be limited in minimum degree, smooth running noise is low；Design is reasonable, easy to maintenance, easily divides
Solution installation, minimum parts count and simple lubrication, make cycloidal planetary gear speed reducer reliable.
Above-described embodiment, is only the better embodiment of the present invention, therefore all structures described according to present patent application scope
Make, the equivalent change or modification that feature and principle are done, be included in the range of present patent application.
