Description

The transmission device of wall surface grinding machine
Technical field
The present invention relates to technical field of tools, especially relate to a kind of transmission device of wall surface grinding machine.
Background technology
Wall surface grinding machine is a kind of instrument replacing the hand-held sand papering metope of Traditional Man or object, to reach smooth, dustless, protects the able-bodied object of workman.Usually, wall surface grinding machine is made up of housing, dedusting protective cover, the motor be arranged in shell, the parts such as gear drive of driving shaft that are arranged at polishing pad in dedusting protective cover and connect motor shaft and polishing pad.That is, this motor is arranged in housing, by electric machine rotation, and by gear drive speed change, is delivered to the driving shaft of polishing pad and then drives polishing pad to rotate, completing polishing.Its defect is: transmission speed ratio is little, and the moment of torsion overcome needed for motor is comparatively large, thus power hungry is comparatively large, and transmission is stable not, is easy to burn-out motor.
Summary of the invention
The object of this invention is to provide a kind of transmission device of wall surface grinding machine, it has, and transmission speed ratio is large, Stability Analysis of Structures, and the feature of not easy burn-out motor.
The technical solution adopted in the present invention is: the transmission device of wall surface grinding machine, moment of torsion for the rotor by motor is passed to polishing pad, this motor is fixed on the housing upper of wall surface grinding machine, and this polishing pad is articulated in this lower housing portion, and the transmission device of described wall surface grinding machine comprises:
---be fixed on this epitrochanterian driving gear;
---to be fixed on this housing and there is the fixed gear ring of internal tooth;
---the planet carrier be enclosed within this driving gear of matched in clearance;
---be articulated at least 3 the planet teeth arranged on this planet carrier and around this driving gear uniformly, those planet teeth include superposed canine tooth and are positioned at the little tooth of bottom, and canine tooth on same planet tooth and little tooth are coaxially fixed together;
---be articulated in the output panel on this housing, this output panel bottom is provided with and is provided with the output gear with internal tooth to the power output shaft of downward-extension, top; And
This driving gear engages the canine tooth on those planet tooth tops;
The canine tooth on those planet tooth tops engages this fixed gear ring;
The little tooth of those planet tooth bottoms engages this output gear;
This power output shaft connects this polishing pad.
The present invention is advantageously: transmission speed ratio is large, Stability Analysis of Structures, and not easy burn-out motor.The transmission device of wall surface grinding machine of the present invention forms the structure of a planetary reduction gear, thus given full play to that planetary reduction gear torque transfer is stable, slowing effect preferably advantage, then power hungry is less, when starting without the need to overcoming great resistance, and not easily burn-out motor then.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of wall surface grinding machine of the present invention;
Fig. 2 is the schematic perspective view of wall surface grinding machine of the present invention;
Fig. 3 is the perspective exploded view of the transmission device of the wall surface grinding machine of embodiments of the invention.
Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 to Fig. 3: the transmission device of wall surface grinding machine, and the moment of torsion for the rotor 100 by motor is passed to polishing pad 200.Wherein, this motor is fixed on housing 300 top of wall surface grinding machine, and this polishing pad 200 is articulated in this housing 300 bottom.More specifically, the transmission device of this wall surface grinding machine comprises: the parts such as driving gear 10, fixed gear ring 20, planet carrier 30, planet tooth 40, output panel 50.
Wherein:
This driving gear 10 is fixed on this rotor 100.That is, this driving gear 10 rotates along with this rotor 100.
This fixed gear ring 20 to be fixed on this housing 300 and to have internal tooth.
Being enclosed within this driving gear 10 of this planet carrier 30 matched in clearance.More specifically, this planet carrier 30 is sleeve-shaped, can rotate freely with the central axis of this driving gear 10.Certainly, this planet carrier 30 can adopt the mode be articulated on this housing 300.
This planet tooth 40 is at least 3, and those planet teeth 40 to be all articulated on this planet carrier 30 and evenly to arrange around this driving gear 10.Meanwhile, those planet teeth 40 include superposed canine tooth 41 and are positioned at the little tooth 42 of bottom, and canine tooth 41 on same planet tooth 40 and little tooth 42 are coaxially fixed together.That is, corresponding canine tooth 41 and little tooth 42 can be structure as a whole.
This output panel 50 is articulated on this housing 300.This output panel 50 bottom is provided with and is provided with the output gear 51 with internal tooth to the power output shaft 52 of downward-extension, top.
More specifically:
This driving gear 10 engages the canine tooth 41 on those planet tooth 40 tops, and the canine tooth 41 on those planet tooth 40 tops engages this fixed gear ring 20, and the little tooth 42 of those planet tooth 40 bottoms engages this output gear 51, and this power output shaft 52 connects this polishing pad 200.
Like this, after this rotor rotates, this driving gear is driven to rotate, this driving gear drives those canine tooths to rotate, and those planet teeth produce revolution while rotation then, and this little cingulum moves this output gear and rotates, and then this output panel rotates, this power output shaft rotates along with this output panel, and finally this power output shaft drives this polishing pad to rotate, and realizes the transmission of whole wall surface grinding machine.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
