Novel rotary disc type planetary reduction gearbox structure

Abstract

The invention discloses a novel rotary disc type planetary reduction gearbox structure. The rotating speed can be stably reduced through multi-stage speed reduction, and a rotary supporting inner tooth engaging structure is adopted in the speed reduction structure, so that the bearing capacity and the impact force are effectively improved; the upper reduction gearbox is independently mounted, so that the upper reduction gearbox is convenient to maintain and the cost investment is reduced. Lubricating oil in a box body is effectively prevented from being lost through the action of an oil seal of an input shaft and an oil seal of a second gear shaft; and when the planetary reduction gearbox is connected to a rotary support, under the action of the oil seals, the lubricating oil in the box body of the planetary reduction gearbox is not lost, and all transmission parts are lubricated and covered, so that the effect of comprehensively protecting the reduction gearbox is achieved, and the service life is prolonged. The novel rotary disc type planetary reduction gearbox structure is reasonable in structure, has the advantages of being convenient to use, stable in rotating speed, long in service life and the like, and solves the problem that a reduction gearbox of a common vertical shaft planetary stirrer is high in production and maintenance cost effectively.

Description

technical field [0001] The invention relates to the field of reduction boxes for concrete mixers, in particular to a novel rotary disk type planetary reduction box structure. Background technique [0002] In the known technology, the general vertical axis planetary mixer gearbox is the operation mode of revolution and rotation, its volume is large, the structure is more complex, and it is composed of upper and lower parts. The upper gearbox casing is fixed on the mixer, and the lower planetary gearbox is Rotation produces revolution and rotation, and the input part is often completed by a large motor and multiple sets of planetary transmissions, which greatly increases development costs and maintenance costs. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, a new type of rotary disk type planetary reduction box structure is provided. The problem of high production and maint...
