Abstract
The utility model discloses a single arm separation type planet carrier-planet gear transmission structure. The transmission structure comprises a planet carrier and is characterized in that the planet carrier is a single arm type planet carrier and provided with a planet shaft, a plant gear is fixedly mounted on the planet shaft, the planet shaft penetrates through the planet carrier and the planet gear so as to fixedly connect the planet carrier with the planet gear, a shaft baffle ring is arranged between the planet shaft and the planet gear, and a hole baffle ring is arranged between the planet shaft and the planet gear. By virtue of the single arm type planet carrier of the transmission structure disclosed by the utility model, a lot of machining time is reduced while the strength is ensured, and the efficiency is improved; in addition, as the planet shaft is matched with the planet carrier in split interference fit, the machining difficulty is greatly reduced, the volume and the weight of a blank material are reduced, the production efficiency is improved, the cost is reduced, and the service life is ensured.
Description
Technical field
The utility model belongs to Gear Production manufacturing technology field, specifically, relates to a kind of single armed separating planet frame planetary gear transmission mechanism.
Background technique
Planetary gears is comprised of planet carrier, sun gear, internal gear and a plurality of planetary pinion, wherein on planet carrier, be distributed with one heart a plurality of planet wheel shafts, each planetary pinion is arranged on planet wheel shaft separately, make each planetary pinion can with the sun gear outer gearing, again can with internal gear in mesh.Because planetary gears has the advantages such as compact structure, stable drive, slewing range be wide, and be widely used on multiple machinery.
The planetary speed reducer planetary structure of application is substantially all the both arms monolithic construction in the market, and not only planetary mechanism weight is large to adopt this mechanism, and space is large, and manufacture cost is high, and processing difficulties, easily scrap.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and a kind of reasonable in design is provided, and single armed separating planet frame planetary gear transmission mechanism little, that processing is simple and durable takes up room.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of single armed separating planet frame planetary gear transmission mechanism, comprise planet carrier, and it is characterized in that: described planet carrier is the single arm type planet carrier, on planet carrier, is provided with planet axis, on planet axis, is installed with planet wheel; Described planet axis runs through and is fixedly connected with planet carrier and planet wheel.
Described planet axis is cylindric, and the outer surface roughness of planet axis reaches Ra0.8.
On described planet carrier, be provided with through hole, the through hole inner side surface contacts with planet axis, and the roughness of through hole inner side surface reaches Ra1.6.
Described through hole inner side surface connects planet axis by interference fit u6/H7.
Described planet carrier and planet axis are to forge that quenching with Subsequent tempering is made and tensile strength reaches planet carrier and the planet axis of 900MPa by the 42CrMo material.
Between described planet axis and planet wheel, be provided with shaft block ring.
The porose back-up ring of using is set between described planet axis and planet wheel.
On described planet carrier, be provided with jacking block.
Owing to having adopted technique scheme, compared with prior art, the utility model utilizes the single arm type planet carrier, in proof strength, has saved a large amount of process times, has improved efficiency, and planet axis adopts the split interference to be connected cooperation with planet carrier, the decrease difficulty of processing, reduce the blank material volume and weight, enhances productivity, cost-saving, guaranteed working life.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments simultaneously.
