Abstract
The utility model relates to a transmission mechanism for grinding heads of grinding machines, which comprises an input shaft, an output shaft and a retarding mechanism which is connected with the two shafts. The utility model is provided with an eccentric shaft which is transmitted and connected with the input shaft, the eccentric shaft is sheathed with a planetary gear, and the eccentric shaft is connected with the planetary gear via a bearing. The planetary gear is coaxially and fixedly connected with an output shaft and is provided with a central inner gear, and the central inner gear is engaged with the planetary gear. With the structure, the utility model can direct drive a grinding disc via the inner engaged planetary gear and is suitable for grinding flat work pieces, and the utility model has the advantages of good grinding effect and high work efficiency.
Description
The utility model relates to a kind of transmission mechanism of grinder bistrique, in particular for the transmission mechanism of portable valve grinding machine.
Grinder of the prior art, its transmission mechanism generally include power shaft, output shaft reaches and the reducing gear of the two driving coupling, and the abrasive disk of grinder is packed on the drive joint that connects firmly with output shaft.Grinder with this transmission mechanism, not good to the grinding effect of flat work pieces.
The purpose of this utility model just provides a kind of transmission mechanism of grinder bistrique, has the grinder of this transmission mechanism, is very suitable for the grinding of flat work pieces, and its grinding effect is good.
The technical solution of the utility model is; A kind of transmission mechanism of grinder bistrique, comprise that power shaft, output shaft reach and the reducing gear of the two driving coupling, its special character is the eccentric shaft that is provided with the power shaft driving coupling, eccentric shaft is provided with planetary gear, the two connects by bearing, planetary gear connects firmly with output shaft is coaxial, is provided with the center internal gear, and the center internal gear is meshed with planetary gear.
Above-mentioned power shaft can connect firmly together with eccentric shaft.
Perhaps pass through the bevel gears driving coupling between power shaft and the eccentric shaft.
The utility model is owing to adopt said structure, the abrasive disk of grinder is packed on the driving head that connects firmly with output shaft, directly drive abrasive disk by internal-gearing planet gear, form the grinding transmission mechanism of hypocycloid track, make abrasive disk do the plane motion of hypocycloid track, be very suitable for the grinding of flat work pieces, its grinding effect is good and work efficiency is high.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of embodiment two;
Fig. 3 is the structural representation of embodiment three.
Referring to Fig. 1～3, the utility model comprises that power shaft 6, output shaft 2 reach and the reducing gear of the two driving coupling, the utility model is provided with the eccentric shaft 5 with power shaft 6 driving coupling, be arranged with planetary gear 3 on the eccentric shaft 5, planetary gear 3 connects by bearing 7 with eccentric shaft 5, planetary gear 3 and output shaft 2 coaxial connecting firmly are fixedly connected with drive joint 1 on the output shaft 2, the abrasive disk of grinder is packed on the drive joint 1.The utility model also is provided with center internal gear 4, and center internal gear 4 is meshed with planet halogen wheel 3.
On the basis of said structure, can provide following examples according to the connecting mode of power shaft 6 and eccentric shaft 5.
Embodiment one: output shaft 6 connects firmly together (referring to Fig. 1) with eccentric shaft 5.This structure is used for grinder, is particularly suitable for grinding the sealing surface of gate valve flap.
Embodiment two: pass through bevel gears 8 driving coupling (referring to Fig. 2) between power shaft 6 and the eccentric shaft 5.This structure is used for grinder, is particularly suitable for grinding the sealing surface of gate valve body.
Embodiment three: pass through cylindrical gear mechanism 9, bevel gears 10 driving coupling (referring to Fig. 3) between power shaft 6 and the eccentric shaft 5.This structure is used for grinder, is particularly suitable for grinding the sealing surface of small-sized gate valve body.
