Description
Technical field
The utility model belongs to mechanical field, is specifically related to the planet carrier bearing lubrication structure that a kind of super sized type is shunted the Gear Planet Transmission gearbox more.
Background technique
Gear Planet Transmission has that compact structure, bearing capacity are big, stable drive, efficient height, easy to install, the life-span is long and noise is low characteristics.Extensively apply to industries such as building materials, metallurgy, mine, the energy.The lubricated of Domestic market Gear Planet Transmission gearbox mainly is bath-splash lubrication or external recycle oil pressure lubrication at present.Often adopt planet wheel more than three groups for the super sized type Gear Planet Transmission, to realize the multirow star-wheel shunting of power.The form of bearing also often adopts sliding bearing because of the influence of factors such as structure and manufacture cost.The block bearing of planet wheel is not only wanted autobiography, and will revolve round the sun along sun gear, often can not keep continuously the lubricated of this bearing, and lubrication effect is undesirable, and superheating phenomenon appears in bearing easily, causes damage of bearings.
Summary of the invention
The purpose of this utility model is: design the planet carrier bearing lubrication structure that a kind of super sized type is shunted the Gear Planet Transmission gearbox more, can be simultaneously to the lubricating structure of the sphere bearing shell sliding bearing continuous oil supply of the cylinder bearing shell sliding bearing of planet carrier supporting and the supporting of a plurality of planet wheel, between the sphere bearing shell that cylinder bearing shell that planet carrier supports and a plurality of planet wheel support, form the feeding gallery that is interconnected, lubricant oil is guided to simultaneously the oil groove of cylinder bearing shell and sphere bearing shell, realization is to the continuously uninterrupted fuel feeding of sliding bearing, lubrication effect ideal.
Technical solution of the present utility model is: this gearbox comprises casing, planet carrier, the cylinder bearing shell, feeding gallery, gland, the sphere bearing shell, planet wheel, ring gear, planet wheel shaft, sun gear, ring gear is installed in the casing, planet carrier is installed in the casing through the sliding bearing of cylinder bearing shell, planet wheel is installed in the planet carrier by the sliding bearing and the planet wheel shaft of sphere bearing shell, planet wheel is positioned on the planet wheel shaft by the sphere bearing shell, planet wheel shaft is a split-type structural, the sphere bearing shell is fixed in the planet wheel by gland, sun gear is positioned in the middle of each planet wheel, it is characterized in that: be the sliding bearing of spherical axis tile structure form in the planet wheel, planet wheel can freely swing along with the contact situation of the flank of tooth during work, guarantees that the teeth directional load distribution is even; Be provided with the radial and axial oil guiding hole of mutual perforation between cylinder bearing shell and a plurality of sphere bearing shell, interconnect the formation feeding gallery between the oil guiding hole, the feeding gallery two ends are communicated with the oil groove of cylinder bearing shell and the oil groove of sphere bearing shell respectively.
During work, sun gear rotates, the rotation and along the sun gear revolution under sun gear and ring gear acting in conjunction of a plurality of planet wheels, and planet wheel drives planet carrier by sphere bearing shell and planet wheel shaft and rotates; The feeding gallery that lubricant oil in the cylinder bearing shell oil groove forms along oil guiding hole enters the oil groove of the sphere bearing shell in a plurality of planet wheels, to each bearing shell continuous lubrication.
The utlity model has following advantage: 1. the fuel feeding of sphere bearing shell is not subjected to planet wheel and the revolution of sphere bearing shell the position is unfixed to influence, sphere bearing shell fuel feeding is kept continuously uninterrupted; 2. lubricant oil flows does not have pipe joint along the journey asphalt channel and connects, in use can be not former thereby loosening, solid and reliable because of vibration etc.; 3. because the fitting surface that asphalt channel is flowed through is interference fit, can not occur as the common loosening and oil seepage phenomena of common lubricating pipe.
