Abstract
The utility model discloses an oil leakage preventing device for a planetary grinding head, which comprises a large gear, a large gear shaft component, at least one planetary gear and at least one planetary gear shaft component, which are arranged in a grinding head casing. Each planetary shaft component comprises a planetary shaft, a shaft bushing, a bearing block, an upper bearing, a lower bearing and at least one lower seal ring, no oil through hole is arranged on the bearing blocks, and at least one upper seal ring is arranged between the upper portion of each bearing block and the corresponding shaft bushing to enable a closed cavity to be formed in the bearing block between each upper seal ring and the corresponding lower seal ring. By means of the oil leakage preventing device, the large gear shaft component can be lubricated by gear oil while the planetary gear shaft component can be lubricated by lubricating grease, leakage can be avoided, and the problem of oil leakage of the planetary gear shaft component of the planetary grinding head is effectively solved.
Description
Technical field
The utility model relates to a kind of planet grinding head anti-oil leakage device that is mainly used in ceramic brick surface processing.
Background technology
At present; In the Surface Machining process of Ceramic Tiles; Usually in rough polishing operation and coating film making process; Often need use planet grinding head as shown in Figure 3, its structure mainly is that parts such as gear wheel 2, Large Gear Shaft During assembly 3, at least one planetary gear 4 and at least one planet wheel spindle assembly are set in bistrique housing 1, and each planet wheel spindle assembly mainly is made up of planet axis 51, axle sleeve 52, bearing block 53, upper bearing (metal) 54, lower bearing 55 and at least one lower seal 56.The environment for use of this kind bistrique is poor, mainly is that the bistrique internal temperature is higher, and the bistrique vibration is big, and the external environment condition dust is big or the like, causes the lower seal in the planet wheel spindle assembly to lose efficacy and leakage of oil easily.On the other hand, as shown in Figure 4, planet grinding head adopts gear oil 6 lubricated usually; The bearing block 53 of the planet wheel spindle assembly of planet grinding head can be offered oil through 531 to introduce gear oil to planet wheel spindle assembly inner chamber, and like this, planet wheel spindle assembly inner chamber has been full of gear oil; Gear oil failed lower seal from the asteroid shaft assembly is spilt, cause the planet grinding head cisco unity malfunction, cause in actual motion fault higher; Maintenance load is bigger, has influenced production.
The utility model content
The purpose of the utility model is the weak point to prior art, and a kind of planet grinding head anti-oil leakage device simple in structure is provided, to solve the leakage of oil problem of existing planet grinding head.
For achieving the above object, the utility model adopts following technical scheme:
The planet grinding head anti-oil leakage device; Comprise the gear wheel, Large Gear Shaft During assembly, at least one planetary gear and at least one the planet wheel spindle assembly that are arranged in the bistrique housing, each planet wheel spindle assembly comprises planet axis, axle sleeve, bearing block, upper bearing (metal), lower bearing and at least one lower seal; Oil through is not set on the said bearing block, and is provided with sealing ring at least one between top and the axle sleeve so that go up the closed chamber of the inner formation of bearing block between sealing ring and the lower seal.
Further, the upper axial of said bearing block extends to form sealing ring construction section on, said at least one sealing ring be arranged on this between sealing ring construction section and axle sleeve.
As preferably, packing lubrication grease in the said closed chamber, and fill gear oil in the said Large Gear Shaft During assembly.
The utility model can make the Large Gear Shaft During assembly adopt gear oil lubricated, and the planet wheel spindle assembly adopts lubricant grease lubricated, is not easy to leak, and efficiently solves the leakage of oil problem of the planet wheel spindle assembly of planet grinding head through adopting said structure.

Combine accompanying drawing and embodiment that the utility model is described further at present.
The specific embodiment
Like Fig. 3 and shown in Figure 4; The described planet grinding head anti-oil leakage device of the utility model; Mainly comprise the gear wheel 2, Large Gear Shaft During assembly 3, at least one planetary gear 4 and at least one the planet wheel spindle assembly that are arranged on bistrique housing 1, and each planet wheel spindle assembly is made up of planet axis 51, axle sleeve 52, bearing block 53, upper bearing (metal) 54, lower bearing 55, lower seal 56 and last sealing ring 57 mainly.Bearing block 53 is not provided with oil through; And upper axial extends to form sealing ring construction section 532 on; Last sealing ring 57 is arranged on this between sealing ring construction section 532 and axle sleeve 52, makes that bearing block 53 between sealing ring 57 and the lower seal 56 is inner to form a closed chamber 533.Packing lubrication grease in the closed chamber 533, and Large Gear Shaft During assembly 3 adopts gear oil 6 lubricated.
The course of work of the utility model is following:
Gear wheel is fixed, and planetary gear and gear wheel mesh and rotate around gear wheel, thereby makes planetary gear produce rotation.Planetary gear, three parts of planet axis and emery wheel are connected and installed and are in the same place, and emery wheel rotates with planetary gear.The emery wheel that is rotating carries out grinding to processing object.In the bistrique operation process, the Large Gear Shaft During assembly adopts gear oil lubricated, but gear oil can not get in the planet wheel spindle assembly; And the planet wheel spindle assembly adopts the lubricant grease of mobile difference to be lubricated, and is not easy to leak, thereby efficiently solves the leakage of oil problem of planet grinding head.
