Description

Planet-gear speed reducer

Technical field

The utility model relates to a kind of transmission device, specifically, relates to a kind of planet-gear speed reducer.

Background technique

In prior art, there is following defect in the planet-gear speed reducer being applied on microtilling machine: 1, be fixed on disk for too thin (diameter is 12mm) of planetary pivot pin is installed, easy-rupturing damages, and working life is short; 2, be located at the central gear of disc centre and disk and be two and be independently individually fixed together by welding means, in actual cultivating procedure, the stressed crack that easily occurs, welding part, even can cause central gear come off and break down from disk; 3, planetary two face structure differences, when mounted, because needs are distinguished positive and negative, and lose time, and are not easy to assembling.

Model utility content

The purpose of this utility model is, a kind of failure rate is low, long service life is provided, is convenient to the planet-gear speed reducer of assembling, to solve above-mentioned technical problem.

For achieving the above object, the technological scheme that the utility model adopts is:

A kind of planet-gear speed reducer, comprises shell and transmission inner core is in the enclosure set, and it is characterized in that: described transmission inner core comprises power input shaft, pto＝power take-off, a disk, No. two disks and No. three disks; The inner of described pto＝power take-off is fixedly connected with the center of a disk; On the inner side surface of a described disk, be evenly provided with four dialer pivot pins, on each dialer pivot pin, a dialer planetary pinion be installed; The center of described No. two disks is provided with center hole, and the outer side surface center of No. two disks is provided with the two dialer central gears that are structure as a whole with No. two disks, and described two dialer central gears are meshed with four dialer planetary pinions respectively; On the inner side surface of described No. two disks, be evenly provided with four two dialer pivot pins, on each two dialer pivot pins, two dialer planetary pinions be installed; The center of described No. three disks is provided with center hole, and the outer side surface center of No. three disks is provided with the three dialer central gears that are structure as a whole with No. three disks, and described three dialer central gears are meshed with four two dialer planetary pinions respectively; On the inner side surface of described No. three disks, be evenly provided with four three dialer pivot pins, on each three dialer pivot pins, three dialer planetary pinions be installed; On the inner of described power input shaft, be fixed with power input gear, described power input gear is meshed with four three dialer planetary pinions respectively.

Say further, the diameter of a described dialer pivot pin, two dialer pivot pins, three dialer pivot pins is identical, is all 13-18mm.

Furtherly, the structure of a described dialer planetary pinion, two dialer planetary pinions, planetary two sides of three dialers is identical.

Beneficial effect: owing to having adopted technique scheme, the utlity model has following advantage: 1, two dialer central gears and No. two disks are structure as a whole, three dialer central gears and No. three disks are structure as a whole, and can eliminate the hidden danger that central gear comes off; 2, the diameter overstriking of the pivot pin of each dish is to 13-18mm, firmer; 3, each planetary two side structures are identical, in the time of assembling, without distinguishing positive and negative, are convenient to rapid-assembling, can improve packaging efficiency.
