Description
Technical field
The utility model relates to a kind of solar reduction gear mechanism, the lubricating structure of particularly a kind of solar reduction gear mechanism.
Background technique
As everyone knows, motor has high rotational speed, if directly apply to have on the passive component rotate too fast, damage problems such as passive component intensity and reduction of service life, be provided with reducing gear at present on the motor output shaft to reduce rotating speed, and reducing gear is of a great variety, except the mode of tradition by large and small gear collocation reaches the purpose of deceleration, at present modal the utility model desire that is is at the epicyclic reduction gear of planetary type mechanism of inquiring into improvement.
The great advantage of described epicyclic reduction gear of planetary type mechanism is to improve that conventional gears reducing gear volume is big, problems such as complex structure, running noise and vibrations, so be more suitable for extensively being applied in the various different subject matters; And the formation of epicyclic reduction gear of planetary type machine comprises that mainly one has the housing of interior groove, and in be located at a planet gear train in this housing, this planetary gear set has output shaft, and the planetary pinion by a plurality of tool helical tooths is formed, respectively this planetary pinion is meshed with the set interior groove of housing, and be provided with in the planetary gear set in order to connect a sun gear group of motor, so when revolution, the planetary pinion of planetary gear set of can moving rotates relative to housing, and then reaches the purpose that reduces the output shaft rotating speed.
Though aforementioned existing epicyclic reduction gear of planetary type mechanism can reach the deceleration purpose, but find in the actual use experience: because its planetary pinion rotates and stressed generation end thrust with the helical tooth and the housing interlock of periphery, impelling planetary pinion end face and two side walls to fit and then produce rubs and push effect, add in order to make planetary pinion accurately mesh rotation, general ccontaining planetary space is all quite accurate on location and size, matching gap is quite small, but so cause lubricant oil can't enter problem in the inner axis hole of planetary pinion smoothly, and then cause the phenomenon of its lack of lubrication, thus, produce excessive vibrations and noise in the time of not only can causing it to rotate, the error that more may cause the planetary pinion engagement because of abrasion, and then cause parts to destroy, directly have influence on the working life of gear reduction unit.
At the described problem of leading portion, follow-up have relevant industry to propose some patented technologies to think adaptation then, " the planetary pinion lubricating structure of gear reduction unit " patent of invention as TaiWan, China number of patent application 94130754 is taken off, the prior art scheme mainly is by being arranged with the technology of at least one oil duct at this planetary pinion both sides end face respectively, so that lubricant oil can be clamp-oned in the axis hole by the guiding of described oil duct, reach its lubricated purpose when planetary pinion rotates; Yet, though this kind practice can reach the purpose of its lubricated planetary gear shaft hole, but because its oil duct is to be arranged with in planetary pinion both sides end face area, must be on making again by the moulding of secondary operations mode ability after planetary pinion is made moulding, so obviously can cause the increase of dealer's manufacture cost, be improved the space of breaking through again so partly obviously still have.
So,, how to develop a kind of innovation structure that has more desirable practicability, for relevant dealer must make great efforts to research and develop the target and the direction of breakthrough again at the existing problem of lubricating structure of above-mentioned existing epicyclic reduction gear of planetary type mechanism.
