Abstract
The invention relates to a speed-changing box planetary carrier, in particular to a planetary carrier with planetary gear transmission of an automatic speed-changing box. The speed-changing box planetary carrier comprises a main frame, an auxiliary frame and planetary wheels; the corresponding positions of a main cabinet frame and the auxiliary frame are fixed with cylinders which are of hollow structures; the main frame and the auxiliary frame are fixed by screws penetrating through the cylinders; the diameters of the cylinders of the main frame and the auxiliary frame are consistent; the cylinders are externally provided with planetary wheel shaft sleeves and planetary wheel bearings; and the planetary wheel bearings are externally provided with the planetary wheels. The technical scheme of the invention realizes connection and fixation of the main frame and the auxiliary frame since the main frame and the auxiliary frame are combined by the cylinders, the planetary wheel shaft sleeves and the screws, and has no supporting body between the main frame and the auxiliary frame, thus saving the space for distributing more planetary wheels, being capable of increasing the number of the planetary wheels and improving the strength of a planetary row.
Description
Technical field
The present invention relates to a kind of mechanical device, be specifically related to a kind of planet carrier of automatic transmission case Planetary Gear Transmission.
Background technique
Planet carrier is an important part in Gear Planet Transmission, suffered moment of face maximum.The structural design of planet carrier has very important impact to load distribution and bearing capacity, vibration, noise between each planet wheel, and vehicle gearbox all has certain limitation to size and weight in addition.
High-power automatic transmission case all adopts planetary transmission structure, is that typical speed is higher, simultaneously the larger transmission of moment of torsion.Between the major and minor framework of common planet carrier structure by support connect or be overall structure, because of the support certain space that accounts for, the planet wheel number of arranging is just restricted, and the bearing capacity of planet row and planet wheel number have much relations, determine the power that whole gearbox can transmit, but size and the weight of vehicle to gearbox has again certain restriction, also there are very high requirement in the reliability to gearbox and life-span simultaneously, so the planet wheel number that the planet carrier structure of prior art is arranged is less, bearing capacity is not ideal enough.
Summary of the invention
Unreasonable for planet carrier structure in solution prior art, the planet wheel number of installation is less, and the problem that bearing capacity is not strong the invention provides under a kind of same size and can arrange more multirow star-wheel and the high a kind of planet carrier of bearing capacity.Concrete scheme is as follows: a kind of speed-changing box planetary carrier, comprise main frame, sub-frame and planet wheel, it is characterized in that, on the corresponding position of described main tank bracket and sub-frame, be fixed with cylindrical body, described cylindrical body is hollow structure, and main frame and sub-frame are by fixing through cylindrical screw rod, and main frame is consistent with the cylinder diameter on sub-frame, cylindrical body overcoat has planet wheel axle sleeve and planet wheel bearing, and described planet wheel bearing is provided with planet wheel outward.
Another optimal way of the present invention: have oil groove on described cylindrical body.
Another optimal way of the present invention: described cylindrical body upper planet wheel both sides are provided with planet wheel back-up ring.
Technological scheme of the present invention due between major and minor framework by cylindrical body, planet wheel axle sleeve with screw combinations realizes main frame, sub-frame is connected and fixed, thereby save space without support for arranging more planet wheel between main frame, sub-frame, can increase planet wheel number, improve the intensity of planet row.

Fig. 2 main frame structure schematic diagram of the present invention
Embodiment
As shown in Figure 1, planet row structure of the present invention, it comprises main frame 1 and sub-frame 2, a side at main frame 1 and sub-frame 2 is provided with corresponding cylindrical body 8, cylindrical body number correspondence on main frame and sub-frame, diameter is also identical, cylindrical centre is hollow structure, cylindrical body on main frame and sub-frame utilizes screw rod 6 to be fixed together after aiming at, on cylindrical body, cover has planet wheel axle sleeve 5 and planet wheel bearing 7, at the outer installation planet wheel 3 of planet wheel bearing 7, the both sides of planet wheel are provided with the planet wheel back-up ring 4 of the major and minor framework that prevents from rubbing.For reducing the friction of planet wheel axle sleeve 5 and cylindrical body 8, have oil groove 9 on cylindrical surface.On major and minor framework, cylindrical body number is identical with planet wheel number, coordinates to realize to support and connection function with planet wheel axle sleeve, on major and minor framework, can be connected with other member by spline or alternate manner, realizes inputing or outputing of power.
Main frame, sub-frame can be also that step hole form or Step Shaft mode are docking together, and recycling screw rod is fixed, and can be also the combination of 3 kinds of modes noted earlier, and means of fixation can also be fixed by snap ring mode.
Due between major and minor framework by cylindrical body 8, planet wheel axle sleeve 5 and screw rod 6 combinations realize main frame, sub-frame is connected and fixed, thereby save space without support for arranging more planet wheel between main frame, sub-frame, can increase planet wheel number, improve the intensity of planet row.
