Description
Technical field
The utility model is related to a kind of cycloidal planetary gear speed reducer, belongs to reductor component technical field.
Background technology
Reductor plays matching rotating speed and transmission torque, reductor between prime mover and working machine or executing agency
It is a kind of relatively accurate machinery, the use of its purpose is to reduce rotating speed, increases torque；Can be divided into list according to transmission series difference
Level and multistage speed reducer；Can be divided into cylindrical gear reducer, conical gear reducer and circular cone, Cylinder Gear according to tooth factory wheel shape
Running wheel reductor；Arrangement form according to transmission can be divided into expansion, shunting and enter shaft type reductor together again；Decelerator is one
Kind constituted individual components are driven by the gear drive that is enclosed in stiff case, worm-drive, pinion-endless screw, be 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.Reductor is generally used for the drive apparatus of low rotation speed large torque,
Motor, internal combustion engine or other power for running at high speed engage output shaft by the few gear of the number of teeth on the input shaft of reductor
On gear wheel reach the purpose of deceleration, common reductor also has and several effect of preferably slowing down is reached to same principle gear
Really, the ratio between number of teeth of big little gear, is exactly gearratio.Existing reductor service life is shorter, it is necessary to often repaired, and
Oscillation Amplitude is big when reductor works, and the noise of generation is larger.
Utility model content
To solve the above problems, the utility model proposes a kind of cycloidal planetary gear speed reducer, compact conformation, volume
It is small；Using reliability, long lifespan durable in use；Vibration and noise is set to be limited in minimum degree, smooth running noise is low；Design is closed
Reason, it is easy to maintenance.
Cycloidal planetary gear speed reducer of the present utility model, including pin wheel housing；Pin gear is installed in the pin wheel housing；Institute
The pin gear for stating pin gear one group of annular array thereon is engaged with two Cycloidal Wheels；The Cycloidal Wheel middle setting has pivoted arm；It is described
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, reduce friction.
Used 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 present utility model employs planet to the utility model
Transmission principle, input shaft and output shaft compact conformation, small volume on same axle center；Major part uses bearing steel, quenched
Treatment obtains high intensity, and driving contact employs rolling friction, using reliability, long lifespan durable in use；Cycloidal pin teeth is nibbled
Close the number of teeth more, overlap coefficient is big and with the stable mechanism of parts, vibration and noise is limited in minimum degree, operating is flat
Steady noise is low；It is reasonable in design, it is easy to maintenance, easily to decompose and install, minimum parts count and simply lubrication make cycloidal-pin wheel
Reductor is reliable.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Each part is labeled as in accompanying 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.
Specific embodiment
As shown in figure 1, cycloidal planetary gear speed reducer of the present utility model, including pin wheel housing 1；Peace in the pin wheel housing 1
Equipped with pin gear 2；The pin gear of the one group of annular array thereon of the pin gear 2 is engaged with two Cycloidal Wheels 3；In the Cycloidal Wheel 3
Between be provided with pivoted arm 4；The end of the pivoted arm 4 is connected with input shaft 5；The rear end of the Cycloidal Wheel 4 is defeated by W away from the side of pivoted arm 4
Go out mechanism 6 and output shaft 7 is installed.
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 holds, 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.
Cycloidal planetary gear speed reducer of the present utility model, equipped with a double eccentric sleeves for 180 ° of dislocation on input shaft,
Two roller bearings are housed on eccentric bushing, H mechanisms are formed, the centre bore of two Cycloidal Wheels is rotary arm bearing on eccentric bushing
Raceway, and be meshed with the pin gear of one group of annular array on pin gear by Cycloidal Wheel, to constitute few teeth difference internal messing reductor
Structure, in order to reduce friction, in speed than in small reductor, pin gear sleeve being carried on pin tooth；When input shaft rotates one with eccentric bushing
Zhou Shi, due to being limited the characteristics of tooth corridor curve in Cycloidal Wheel and its by pin gear upper pin gear, the motion of Cycloidal Wheel turns into
There is revolution and have the plane motion of rotation, when input shaft just circles, eccentric bushing is also rotated one week, and Cycloidal Wheel is in phase negative side
A tooth difference is turned over so as to be slowed down upwards, then by W output mechanisms, by the low speed spinning motion of Cycloidal Wheel by bearing pin,
Output shaft is passed to, so as to obtain relatively low output speed；Gear Planet Transmission principle is employed, input shaft is with output shaft in same axle
Compact conformation, small volume in the heart；Major part uses bearing steel, and quenched treatment obtains high intensity, and driving contact is used
Rolling friction, using reliability, long lifespan durable in use；Cycloidal pin teeth total number of teeth in engagement is more, and overlap coefficient is big and with machine
The stable mechanism of part, makes vibration and noise be limited in minimum degree, and smooth running noise is low；It is reasonable in design, it is easy to maintenance, easily
Decompose and install, minimum parts count and simply lubrication make cycloidal planetary gear speed reducer reliable.
Above-described embodiment, is only better embodiment of the present utility model, therefore all according to the utility model patent claim
The equivalent change or modification that described construction, feature and principle are done, is included in the utility model patent claim.
