Abstract
The utility model discloses a planet carrier, wherein a left plate (1) and a right plate (3) are arranged in parallel, at least two planet pawls (2) are uniformly arranged between the left plate (1) and the right plate (3) in the circumferential direction, the left plate (1), the planet pawls (2) and the right plate (3) are integrally arranged, one end of the planet pawls (2) is arranged on an end surface of the left plate (1), the other ends of the planet pawls (2) are arranged on the end surface of the right plate (3), at least a left through hole (1a) is arranged on the end surface of the left plate (1), the left through hole (1a) and the planet pawls (2) are arranged in a dislocated mode, and a right through hole (3a) which is corresponding to the left through hole (1a) is arranged on the end surface of the right plate (3). The left plate and the right plate of the planet carrier and the planet pawls are connected together in an integrated mode, the tolerable maximum moment of the planet carrier is increased, and the planet carrier has the advantages of ingenious design, low improvement cost and long service life and the like.
Description
Technical field
The utility model relates to a kind of auto parts, particularly a kind of gearbox inferior planet row's planet carrier.
Background technique
Planet carrier is one of main member of planetary type gear transmission unit, and planet wheel shaft or bearing just are contained on the planet carrier.When planet wheel during as basic building block, planet carrier is the part that bears the moment of face maximum in the planet row.The board-like planet carrier of bilateral is best a kind of of rigidity in the planet carrier structure, is furnished with the planet pawl between two side plates, and the board-like planet carrier of bilateral that adopts on the market is normally one-body molded with left sideboard and planet pawl, planet pawl and right sideboard is welded together again.The maximum moment that this processing mode causes planet carrier integral body to bear is less, and the life-span reduces greatly when bearing than high-torque.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of integral type planet carrier that can bear than high-torque.
The technical solution of the utility model is as follows: a kind of integral type planet carrier, comprise left sideboard (1), planet pawl (2) and right sideboard (3), described left sideboard (1) and right sideboard (3) are parallel to each other, between left sideboard (1) and right sideboard (3) by circumferentially evenly being provided with at least two planet pawls (2), described left sideboard (1), planet pawl (2), right sideboard (3) is one-body molded, one end of this planet pawl (2) is on the end face of left sideboard (1), and the other end of this planet pawl (2) is on the end face of right sideboard (3); End face at described left sideboard (1) offers at least one left through hole (1a), this left through hole (1a) and planet pawl (2) shift to install, and offer the right through hole (3a) corresponding with left through hole (1a) at the end face of described right sideboard (3).
Adopt above technological scheme, in use, planet wheel is arranged between per two planet pawls, then pass left through hole, planet wheel and right through hole by planet wheel shaft, planet wheel is rotatably connected between left sideboard and right sideboard.Because planet pawl and left sideboard and right sideboard all are formed in one, so that the maximum moment that planet carrier can bear improves greatly, have improved simultaneously the working life of planet carrier.
In order to make planet wheel shaft more firm with being connected of planet carrier, planet wheel shaft is riveted on the right through hole (3a), all offer two right shrinkage pools (4) in the right end of each described right through hole (3a), this right shrinkage pool (4) is arranged on the right side of right sideboard (3), and two right shrinkage pools (4) are symmetricly set on the both sides of right through hole (3a), when riveted joint die are pressed on the right through hole (3a).
In order to make planet wheel shaft more firm with being connected of planet carrier, planet wheel shaft is riveted on the right through hole (3a), all offer two left shrinkage pools (5) in the right end of each described left through hole (1a), this left shrinkage pool (5) is arranged on the left side of left sideboard (1), and two left shrinkage pools (5) are symmetricly set on the both sides of left through hole (1a), when riveted joint die are pressed on the right through hole (3a).
Offer oil guiding hole (6) on the described right sideboard (3).
For the center of gravity that makes planet carrier does not deflect, described planet pawl (2), left through hole (1a) are identical with the quantity of right through hole (3a).
Beneficial effect: the utility model all links together two side plates of planet carrier with the planet pawl is one-body molded, has improved the maximum moment that planet carrier can bear, and has ingenious, the characteristics such as reforming cost is low, long service life of design.
