Description
Technical field
The present invention provides a kind of Modularized Precision cycloidal reducer, is wanted for robot revolute joint, lathe turntable etc.
Seek the device of high rotating accuracy occasion.
Background technology
BXJ retarders are a kind of new drive devices to grow up on the basis of cycloidal-pin wheel, transmission big with rigidity
, large carrying capacity bigger than range, kinematic accuracy are high, transmission efficiency and return difference are small, the series of advantages such as small.
BXJ retarders are made of involute cylinder planetary gear speed reducing mechanism and cycloidal-pin wheel mechanism two parts, cycloid grade
Input is made of at least 2 crank axles, constitutes 1 or more parallelogram, and each planetary gear of planetary stage difference is corresponding
Crank axle is coupled by spline, this just proposes matching requirements to the internal spline of planetary gear and external tooth relative phase.In other words,
Under normal circumstances, the internal spline of every planetary gear and external tooth relative phase are different, and need to accurately ensure, otherwise can not fill
Match, this proposes very high requirement to the manufacture of planetary gear, thereby reduces production efficiency, increases manufacturing cost.
Invention content
The purpose of the present invention is to provide a kind of reasonable for structure, low cost, the revolutions of modular Modularized Precision cycloid to close
Save retarder.
Technical scheme of the present invention：A kind of Modularized Precision cycloid revolute joint retarder, 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 be supported in pin wheel housing, n
Crank axle is threaded through in planet carrier and has two eccentric parts of dislocation 180, and eccentric part passes through roller bearing and Cycloidal Wheel joins
It connects, gear pin of the Cycloidal Wheel through being contained in pin wheel housing inner wall gear pin hole is engaged in pin wheel housing, and crank axle both ends pass through circle
Taper roller bearing is supported in planet carrier and connects firmly planetary gear, more than two crank axles, Cycloidal Wheel and row by spline and baffle ring
Carrier constitutes parallelogram mechanism, and central gear, which is worn to connect, is supported on planet carrier, in Cycloidal Wheel and teeth portion and planetary gear are nibbled thereon
It closes；It is characterized in that：N is uniformly engaged around the central gear and only connects firmly the planetary gear on n crank axle, and planetary gear is in
The number of teeth of heart gear and multiple for n, the internal spline of planetary gear are consistent with the relative phase of external tooth thereon.
The present invention is excellent by the number of teeth of central gear and planetary gear and the multiple for being set as every retarder planetary gear quantity
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；Under the premise of ensureing transmission intensity enough, the planetary gear internal spline of a variety of seat No. retarders
Parameter can be consistent, thus only needs a small amount of cutter and frock clamp that can meet the production requirement of entire series retarder, saves
A large amount of man power and material, while production efficiency is improved, and then significantly reduce the production cost of retarder entire series；
Parts except planetary gear are all shaped, the installation space of centre wheel and planetary gear is reserved, in demand difference reduction ratio,
Corresponding centre wheel and planetary gear only need to be installed, to realize modularized production, pole is conducive to large-scale production, saves production
The management cost of product, and improve the speed in response market.

Specific implementation mode
Below in conjunction with drawings and examples, the invention will be further described.
A kind of Modularized Precision cycloid revolute joint retarder shown in Fig. 1,2,3 includes pin wheel housing 1, planet carrier 2, crank axle
3, gear pin 4, Cycloidal Wheel 5, central gear 6, planetary gear 7, planet carrier are worn to connect through rolling bearing and be supported in pin wheel housing, and n bent
Arbor is threaded through in planet carrier and has two eccentric parts of dislocation 180, and eccentric part passes through roller bearing and Cycloidal Wheel joins
It connects, gear pin of the Cycloidal Wheel through being contained in pin wheel housing inner wall gear pin hole is engaged in pin wheel housing, and crank axle both ends pass through circle
Taper roller bearing is supported in planet carrier and connects firmly planetary gear, more than two crank axles, Cycloidal Wheel and row by spline and baffle ring
Carrier constitutes parallelogram mechanism, and central gear, which is worn to connect, is supported on planet carrier, in Cycloidal Wheel and teeth portion and planetary gear are nibbled thereon
It closes；It is characterized in that：N is uniformly engaged around the central gear and only connects firmly the planetary gear on n crank axle, and planetary gear is in
The number of teeth of heart gear and 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 at the positions planetary gear b, planetary gear b engagement sections
It is moved between the opposite planetary gear a working pitch points of pointThe working pitch point of a pitch, centre wheel moves backwardSection
Away from.The number of teeth of 3 planetary gears and 1 centre wheel can be divided exactly by 3 in the present embodiment, then planetary gear can be smoothly packed into；If cannot
Divide exactly, inevitable poor 1/3 or 2/3 pitch, it is clear that if planetary gear differs 1/3 pitch, centre wheel differs 2/3 pitch, or row
Star-wheel differs 2/3 pitch, and centre wheel differs 1/3 pitch, and planetary gear also can be with centre wheel correct engagement.If to sum up centre wheel
With the number of teeth of planetary gear and for 3 multiple, then the internal spline of the 3 planetary gears and relative phase of external tooth is consistent correctly to nibble
It closes.
