Description

Technical Field

[0001] This utility model relates to the field of flooring machine technology, and in particular to a self-lubricating planetary gear disk structure for flooring machines. Background Technology

[0002] In the construction industry, before the final plastering of new floors and slabs, or before the renovation of old floors and slabs, the ground and floor surfaces must be roughened and the unevenness of the concrete or the thickness exceeding the design requirements during the previous construction must be removed.

[0003] Existing flooring machines on the market produce a lot of noise during grinding. Operators usually add lubricating oil to reduce the noise. However, using lubricating oil requires sealing the planetary gear set, which increases the cost of the flooring machine. Therefore, a self-lubricating planetary gear disk structure for flooring machines was designed. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating planetary gear disk structure for flooring machines to address the shortcomings of existing technologies. This self-lubricating planetary gear disk structure for flooring machines has a novel design and simple structure. The planetary gears adopt a self-lubricating structure, which effectively reduces noise and lowers the production cost of flooring machines.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A self-lubricating planetary gear disk structure for a flooring machine is characterized by: a circular gearbox with several grinding discs mounted on the lower end of the gearbox; a horizontally arranged planetary drive gear mounted on the upper end of the gearbox; several driven pinions meshing around the periphery of the planetary drive gear and connecting to the gearbox; the driven pinions mounted on the upper end of the gearbox cover; the planetary drive gear mounted on the upper surface of the gearbox cover; several annularly arranged recesses on the upper end of the gearbox cover; self-lubricating gaskets mounted on the upper ends of the recesses and contacting the lower surface of the planetary drive gear.

[0007] The lower end of the gearbox is equipped with at least four grinding discs.

[0008] The planetary drive gear is mounted on the upper center of the upper surface of the gearbox cover via a rotating shaft.

[0009] The self-lubricating gasket is made of polytetrafluoroethylene.

[0010] The beneficial effects of this utility model are as follows: The self-lubricating planetary gear disk structure for floor machines described in this utility model is characterized by: including a circular gearbox, with several grinding discs installed at the lower end of the gearbox, a horizontally arranged planetary drive gear installed at the upper end of the gearbox, and several driven pinions meshing around the periphery of the planetary drive gear, with the driven pinions connected to the gearbox, the driven pinions installed on the upper end of the gearbox cover, and the planetary drive gear installed on the upper end face of the gearbox cover, with several annularly arranged recesses provided on the upper end of the gearbox cover, and self-lubricating gaskets installed at the upper end of the recesses, with the self-lubricating gaskets contacting the lower end face of the planetary drive gear. This invention features a series of annularly arranged recessed holes on the upper part of the gearbox cover, with self-lubricating gaskets installed at the upper ends of these holes. These self-lubricating gaskets contact the lower end face of the planetary drive gear, thus achieving a self-lubricating structure for the planetary drive gear. This effectively reduces noise and lowers the production cost of the flooring machine. Therefore, this invention has the advantages of novel design, simple structure, self-lubricating planetary gears, effective noise reduction, and lower production cost of the flooring machine.
