That assembling type planet carrier has is simple in structure, light, advantage cheaply, thereby uses very extensive.Assembling planet carrier structure kind is many, at present main adopt have 3 kinds of planet carriers.The first planet carrier: planet plate+2 step pin axle+circlip for shaft+packing ring.The advantage of this planet carrier is that bearing pin is easy to process, and bearing pin should not come off; The shortcoming of this planet carrier is that bearing surface, planet plate and packing ring are installed on the second shaft part, and needed tolerance fit is different again, the easy scratch of bearing pin when assembling, and magnitude of interference can not be got too large, makes troubles to bearing assemble.
The second planet carrier: planet plate+straight pin+circlip for shaft, the advantage of this planet carrier is that bearing pin is easy to process, easy to assembly; The shortcoming of this planet carrier is that bearing pin leans on pin-and-hole interference fit completely, and bearing pin wearing and tearing rear pin shaft may come off, and damages speed reducer, has the shortcoming that Safety performance is low.
The third planet carrier: 3 step pin axle+2 circlip for shaft of planet plate+intermediate projections, the advantage of this planet carrier is easy to assembly; The shortcoming of this planet carrier is that the bearing pin in this structure is broad in the middle, small in ends, bearing pin needs No. 2 clamping processing, the precision of bearing pin should not ensure, force bearing point has 2 steps, stress is too concentrated and is easily fractureed, and jump ring takes up room many, has processed complex, precision is low, Safety performance is low and cost of production is high shortcoming.
Summary of the invention
The problem existing for solving prior art, the utility model provides a kind of assembling type planet carrier, and this planet carrier has assembling, easy to process, the advantage that precision is high, Safety performance is high and cost of production is low.
Realizing the technological scheme that the utility model object takes is:
A kind of assembling type planet carrier, at least comprise planet plate, bearing pin, bearing, circlip for shaft and cone end Cock screw, described bearing pin is ladder bearing pin, bearing pin is successively by the first shaft part, the second shaft part and the 3rd shaft part form, the first shaft part, the diameter of the second shaft part and the 3rd shaft part increases progressively successively, the shaft shoulder between the first shaft part and the second shaft part is first shaft shoulder, the shaft shoulder between the second shaft part and the 3rd shaft part is second shaft shoulder, bearing pin is installed in the pin shaft hole of planet plate, interference fit between the second shaft part of bearing pin and the pin shaft hole of planet plate, the bottom of planet plate and the laminating of first shaft shoulder, bearing housing is loaded on the first shaft part, and by circlip for shaft and the second shaft shoulder axially locating, between bearing pin and planet plate, hold Cock screw axially locating by cone, the head of cone end Cock screw is positioned at the second shaft part.
Second shaft shoulder is provided with annular chamfer, and the size of chamfering is 2mm × 20 °.
The second shaft part and the first shaft part, and the poor 5～10mm that is of the diameter of the 3rd shaft part and the second shaft part.
The first shaft part and bearing are Spielpassung.
Described planet plate is fillet equilateral triangle shape, on three fillets of planet plate, is evenly distributed with three pin shaft holes.
As shown from the above technical solution, the bearing pin in this planet carrier is ladder bearing pin, and the diameter of each shaft part increases successively, and bearing pin can machine by clamped one time, and the precision of bearing pin is high, and easy to process, and cost is low.The second shaft part of bearing pin and the pin shaft hole of planet carrier are interference fit, and cone end clamp screw is installed in planet plate prevents that the second shaft part is along bearing pin axial motion; The top of the first shaft part is provided with circlip for shaft, and bearing is stuck between circlip and the second shaft part, prevents bearing axial motion, therefore the Safety performance of this planet carrier is high and easy to assembly.
In sum, this planet carrier is not only processed with easy to assembly, and precision is high, and cost of production is low, and Safety performance is high.
