Abstract
A planetary row device used in a planetary transmission mechanism, in particular to be used on engineering machinery such as loader is disclosed. The utility model is characterized in that a planetary carrier is connected to the planetary axle, and the end of the planetary carrier is directly adjacent to the end of the planetary wheel. Therefore, the fragile parts are fundamentally abolished, and the bending strength of the planetary axle can be increased by thickening the planetary wheel or shortening the span of the planetary axle. On engineering machinery, as the planetary row is installed in planetary transmission mechanisms such as a planetary gearbox or a driving axle, the overhaul interval of the planetary row is the overhaul interval of the planetary transmission mechanism. The whole planetary row usually changes new parts, not only changing damaged small components as before, greatly increased the overhaul interval of the planetary row. The utility model has the advantage of greatly increased overhaul interval, which can increase the production efficiency and decrease the using cost of the engineering machinery which uses the planetary transmission mechanism.
Description
Technical field
The utility model relates to a kind of planetary transmission device that is used for, and is specially adapted to the planet arranging device on the construction machinery and equipments such as loader.
Background technology
Sun and planet gear planet row generally adopts the mode that pad is arranged in the design of the both sides of satellite gear always, and the pad that has is with red copper or copper alloy manufacturing; The pad that has is to make with engineering plastics; Also have plenty of with the pad that hardens.The planet of this structure row's the overhaul phase is mainly by the decision in service life of pad, and design pad main purpose is exactly to allow pad wear and tear to reduce the wearing and tearing of satellite gear and pinion carrier.Because pad is a consumable accessory, service life is short, causes the cycle of planet row's overhaul phase also short.
Summary of the invention
The purpose of this utility model just provides a kind of overhaul life that can effectively prolong planet row, the planet arranging device that can reduce production costs.
Solution of the present utility model is such: be to be connected with on the planet axis pinion carrier, the end face of pinion carrier is directly near the end face of satellite gear.So fundamentally cancelled consumable accessory, thereby and satellite gear can be thickeied or the span of planet axis shortens the bending strength of planet axis is increased, in construction machinery and equipment, because planet row is contained in planetary drive arrangement the insides such as planetary transmission or drive axle, planet row's the overhaul phase is the overhaul phase of these planetary drive-train means just, whole planet row generally is to renew part, only changes the finding of damage before not resembling, and has greatly improved planet row's the overhaul phase.
The utility model has the advantages that the overhaul phase that effectively to improve planet row, and can improve the production efficiency of the mechanical equipment that adopts planetary transmission device and reduce use cost.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
The utility model includes satellite gear 1, planet axis 2, sun wheel 3, needle roller 4, pinion carrier 5, gear ring 6, packing ring 7.
Be connected with pinion carrier 5 on the planet axis 2, the end face of pinion carrier 5 is directly near the end face of satellite gear 1.Thereby thereby satellite gear can be thickeied or the span of planet axis shortens the bending strength of planet axis is increased, and has fundamentally cancelled consumable accessory.
