Description
Technical field
The present invention provides a kind of Modularized Precision cycloidal reducer, is to be used to robot revolute joint, lathe turntable etc. want
Seek the device of high rotating accuracy occasion.
Background technology
BXJ decelerators are a kind of new drive devices to grow up on the basis of cycloidal-pin wheel, have that rigidity is big, transmission
The series of advantages such as, large carrying capacity bigger than scope, kinematic accuracy are high, the small, small volume of transmission efficiency and return difference.
BXJ decelerators are made up of involute cylinder planetary gear speed reducing mechanism and cycloidal-pin wheel mechanism two parts, its cycloid level
Input is made up of at least 2 crank axles, forms more than 1 parallelogram, and each planetary gear of planetary stage difference is corresponding
Crank axle is coupled by spline, and this just proposes matching requirements to the internal spline and external tooth relative phase of planetary gear.In other words,
Generally, the internal spline of every planetary gear and external tooth relative phase are different, and need to accurately ensure, otherwise can not fill
Match somebody with somebody, this manufacture to planetary gear proposes very high requirement, and then reduces production efficiency, adds manufacturing cost.
The content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, low cost, the revolution of modular Modularized Precision cycloid to close
Save decelerator.
Technical scheme：A kind of Modularized Precision cycloid revolute joint decelerator, including pin wheel housing, planet carrier,
Crank axle, gear pin, Cycloidal Wheel, central gear and planetary gear, planet carrier are worn to connect through rolling bearing and are supported in pin wheel housing, n
Crank axle wears in planet carrier and joined with two eccentric parts of dislocation 180, its eccentric part by roller bearing and Cycloidal Wheel
Connect, gear pin of the Cycloidal Wheel through being contained in pin wheel housing inwall gear pin hole is engaged in pin wheel housing, and crank axle both ends pass through circle
Planetary gear, two or more crank axle, Cycloidal Wheel and row are connected firmly in taper roller bearing support planet carrier and by spline and back-up ring
Carrier forms parallel-crank mechanism, and central gear is worn and connects support planet carrier, Cycloidal Wheel is interior and teeth portion and planetary gear are nibbled thereon
Close；It is characterized in that：Uniformly engagement n only connects firmly the planetary gear on n crank axle around the central gear, and planetary gear is with
The number of teeth of heart gear and the multiple for n, the internal spline of planetary gear are consistent with the relative phase of external tooth thereon.
For the present invention by the number of teeth of central gear and planetary gear and the multiple for being set as every decelerator planetary gear quantity, its is excellent
Point has：The internal spline of planetary gear and the phase of external tooth may be set to arbitrary value, need to only ensure it is consistent, it is convenient, reliable simultaneously
Save a large amount of frock clamps；On the premise of transmission intensity enough is ensured, the planetary gear internal spline of a variety of seat No. decelerators
Parameter can be consistent, thus only needs a small amount of cutter and frock clamp to meet the production requirement of entire series decelerator, saves
Substantial amounts of man power and material, while production efficiency is improved, and then significantly reduce the production cost of decelerator entire series；
Parts outside planetary gear are all shaped, reserve the installing space of centre wheel and planetary gear, in demand difference speed reducing ratio,
Corresponding centre wheel and planetary gear need to be only installed, it is achieved thereby that modularized production, pole is beneficial to large-scale production, saves production
The management cost of product, and improve the speed in response market.

Embodiment
Below in conjunction with drawings and examples, the invention will be further described.
A kind of Modularized Precision cycloid revolute joint decelerator shown in Fig. 1,2,3 includes pin wheel housing 1, planet carrier 2, crank axle
3rd, gear pin 4, Cycloidal Wheel 5, central gear 6, planetary gear 7, planet carrier are worn to connect through rolling bearing and are supported in pin wheel housing, and n bent
Arbor wears in planet carrier and joined with two eccentric parts of dislocation 180, its eccentric part by roller bearing and Cycloidal Wheel
Connect, gear pin of the Cycloidal Wheel through being contained in pin wheel housing inwall gear pin hole is engaged in pin wheel housing, and crank axle both ends pass through circle
Planetary gear, two or more crank axle, Cycloidal Wheel and row are connected firmly in taper roller bearing support planet carrier and by spline and back-up ring
Carrier forms parallel-crank mechanism, and central gear is worn and connects support planet carrier, Cycloidal Wheel is interior and teeth portion and planetary gear are nibbled thereon
Close；It is characterized in that：Uniformly engagement n only connects firmly the planetary gear on n crank axle around the central gear, and planetary gear is with
The number of teeth of heart gear and the multiple for n, the internal spline of planetary gear are consistent with the relative phase of external tooth thereon.
If the number of teeth of centre wheel is, the number of teeth of planetary gear is, then relative in planetary gear b opening positions, planetary gear b working pitch points
Moved between planetary gear a working pitch pointsIndividual pitch, the working pitch point of centre wheel move backwardPitch.The present embodiment
In the number of teeth of 3 planetary gears and 1 centre wheel can be divided exactly by 3, then planetary gear can smoothly load；It is inevitable poor if aliquant
1/3 or 2/3 pitch, it is clear that if planetary gear differs 1/3 pitch, centre wheel differs 2/3 pitch, or planetary gear difference 2/3
Individual pitch, centre wheel differ 1/3 pitch, and planetary gear also can be with centre wheel correct engagement.If to sum up centre wheel and planetary gear
The number of teeth and for 3 multiple, then the internal spline of 3 planetary gears and the relative phase of external tooth is consistent can correct engagement.
