One of component, planet wheel spindle or bearing are just on planet carrier.When planetary gear is as basic building block, it is born in mechanism
The maximum part of moment of face.The structure design of planetary gear and manufacture are to the load distribution between each planetary gear so that transmission device
Bearing capacity, noise and vibration etc. have a significant impact.The Rational structure of planet carrier should be in light weight, rigidity is good, be easy to add
Work and assembling.Its common structure form has dual-sided board monoblock type, dual-sided board split and board-like three kinds of one side.Dual-sided board monoblock type
Rigidity it is good.This structure machining amount if using solid forging is very big, therefore available casting and welding method obtain
Structure snd size but are cast or defect easily occur during welding close to the blank of finished product, planet carrier have internal stress, it is necessary to and
When eliminate, there may be deformation when otherwise will influence the intensity of planet carrier, crudy and using.
Conventionally, as the reasons in structure of planet carrier, conventional planet carrier is generally magnesium iron or cast steel is integrally cast
Make and form.Casting technique during casting is complicated, and burning into sand in planetary gear cavity etc. is difficult to clear up, and easily produces stress concentration and casting
Make defect.Meanwhile if when planet carrier uses monoblock cast, workpieces processing is not easy Set and Positioning in processing, and difficulty of processing is big, adds
Work complex process, low production efficiency, planet carrier structure can not be carried out the operation such as dismantling, and use range is limited, it is impossible to is met daily
Use demand.
