The central gear is provided with a first friction face, the bearing pedestal is provided with a second friction face, the first friction face and the second friction face are arranged oppositely, and a certain gap is formed between the first friction face and the second friction face. The axial-limiting antifriction structure is simple, convenient to disassemble and assemble, high in reliability and low in cost.
Description
Technical field
The present invention relates to a kind of planetary drive gear-box, especially about being applicable to the axial limiting of the floating neutral wheel in gear-box and antifriction or other similar structure.
Background technique
In planetary transmission structure gear box designs, central gear is generally axial non-fixed form, in gear-box working procedure, all carry object to reach train, usually requires that central gear floats in axial certain limit.In existing limit stoper, complex structure, central gear can not free floating completely, and bearing can not effectively be lubricated, and reliability is low, and cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, be convenient to dismounting, reliability is high, cost is low axial limiting antifriction structure.
The technological scheme realizing foregoing invention object is: a kind of axial limiting antifriction structure, comprise gear housing, sealing seat, first bolt, central gear, second bolt, bearing, bearing support and end cap, described central gear is installed in gear housing, described sealing seat is fixedly connected with by the first bolt with gear housing, described end cap is fixedly connected with sealing seat by the second bolt, the outer ring of described bearing is installed in the bearing mounting hole of sealing seat, and outer ring and end cap offset, the inner ring of bearing is installed on bearing support, described central gear has the first rubbing surface, described bearing support has the second rubbing surface, described first rubbing surface and the second rubbing surface are arranged face-to-face, and have certain interval between the two.
Described gap is 1 ~ 1.5mm.
O type circle is housed between described sealing seat and gear housing.
One end of the close central gear of described bearing support has shoulder block, and the side of the side of shoulder block and the inner ring of bearing offsets.
Described bearing support has axial mesopore.
Described axial mesopore is taper hole, and the diameter near end cap one end is greater than the diameter near central gear one end.
Described first rubbing surface and the second rubbing surface are harveyed surface.
Described bearing is deep groove ball bearing.
After adopting said structure, due to central gear in gear-box operation process for realize all carry can produce floating, when the first rubbing surface of central gear contacts with the second rubbing surface of bearing support, central gear will drive bearing support and bearing to realize revolution, in central gear operation process, the lubricant oil that train is splashed can be directed at bearing by the axial mesopore of bearing support simultaneously and sentence the lubrication realizing bearing, solve the axial limiting of central gear and the end-face friction problem in rotary stopper process, and realize effectively lubricating and sealing.Structure of the present invention is simple, and be convenient to dismounting, reliability is high, and cost is low.
