Abstract
The utility model discloses a transmission mechanism of a polishing machine, which comprises a driving device, a transmission device connected with the driving device, and a running device connected with the transmission device, wherein the running device comprises an upper polishing sheet, a lower polishing sheet and a support shaft for supporting the lower polishing sheet; a group of radial bearings are arranged below a shaft sleeve of the support shaft; and two groups of bearings are arranged above the shaft sleeve of the support shaft and are respectively double row ball bearings sleeved above the shaft sleeve of the support shaft and plane bearings sleeved below the double row ball bearings. According to the transmission mechanism of the polishing machine, which is disclosed by the utility model, one group of bearings are changed to multiple groups of bearings, so the support shaft is heavily loaded and the stability is good; and by mounting the plane bearings, axial clearances can be eliminated.
Description
Technical field
The utility model relates to the polishing machine mechanical field, is specifically related to a kind of transmission mechanism of polishing machine.
Background technology
The kind of conventional polisher is a lot; We mainly introduce the large-scale automatic numerical control polishing machine that is used for polished glass, pottery etc.; Above this polishing machine is general is polishing mechanism, is provided with transmission mechanism below, shown in accompanying drawing 1; The transmission mechanism of conventional polisher comprises the support axis 2 of drive unit 1, transmission device, running gear and the motion of support running gear; The support axis 2 axle sleeves outside of conventional polisher only is provided with one group of radial ball bearing 3, makes and supports axis 2 stressed little, poor stabilities, and service life is short.
The utility model content
The utility model purpose: the utility model is in order to solve the deficiency of prior art, and a kind of transmission mechanism of polishing machine of stressed big, good stability is provided.
Technical scheme: a kind of transmission mechanism of polishing machine; Comprise drive unit, the transmission device that links to each other with said drive unit, the running gear that links to each other with said transmission device; The back shaft of polished silicon wafer under polished silicon wafer and the support about said running gear comprises; Said back shaft axle sleeve below is provided with one group of radial bearing, and back shaft axle sleeve top is provided with two groups of bearings, is respectively double row ball bearing that is enclosed within back shaft axle sleeve top and the plane bearing that is enclosed within said double row ball bearing below.
As optimization, said drive unit is a motor, and said motor adopts the industrial computer centralized Control.By the industrial computer centralized Control, intelligent strong.
Beneficial effect: the transmission mechanism of the utility model polishing machine, change one group of bearing into many group bearings, make back shaft stressed big, good stability, the dress plane bearing can be eliminated end play.
