Detailed description of the invention
Refer to Fig. 1, an embodiment provides a kind of drill kind tool 100.This drill kind tool 100 includes casing
110, motor 120, planetary gear mechanism, main shaft 140, chuck 150, handle 160 and battery 170.
Casing 110 is closed up by screw by symmetrical two half shells and is assembled.Casing 110 has level
Part and vertical portion two parts, only depict horizontal component, eliminate vertical portion in Fig. 1.Wherein machine
Equipped with parts such as motor 120, planetary gear mechanism, main shafts 140 inside the horizontal component of shell 110, this
Place epicyclic transmission mechanism include three groups of epicyclic trains, these three groups of epicyclic trains from chuck 150 to motor
120 are arranged in order respectively first planet gear train, the second epicyclic train and third planet gear train.Casing
The vertical portion of 110 forms handle, is internally provided with control circuit.Handle is provided with trigger, and trigger can
For the work controlling this drill kind tool 100.Afterbody at handle connects this drill kind tool promising provides energy
The battery of amount.Battery herein is lithium ion battery, and in other embodiments, battery can also be NI-G electricity
The suitably battery such as pond, Ni-MH battery.
Motor 120 in casing 110 is mainly used in exporting rotary motion, and the output of motor 120 is through the third line
The transmission of star gear train, the second epicyclic train and first planet gear train can arrive main shaft 140, such row
Star gear drive is achieved that the rotation of drive shaft 140.Chuck 150 is installed, folder on main shaft 140
Suitable drill bit can be installed as required, when the chuck 150 that rotarily drives of main shaft 140 rotates on 150
Time, it is arranged on the drill bit on chuck 150 and is also achieved that rotation.
First planet gear train, the second epicyclic train and the third line in the casing 110 of this drill kind tool 100
Star gear train all includes planetary gear and for supporting the planet carrier of planetary gear.Wherein the third line galaxy includes
The third line star-wheel 132 and the third line carrier 134.Second epicyclic train includes the second planetary gear 136 and second
Planet carrier 138.First planet gear train includes the first row star-wheel 131 and the first row carrier 133.Casing 110
Inside it is additionally provided with main shaft 140 and jackshaft 160.Main shaft 140 is axially arranged with spindle hole 146 along self.Middle
One end of axle 160 is rotatably located in spindle hole 146, and the other end passes first planet gear train, and fixes
On the planet carrier of the second epicyclic train, i.e. it is fixed on the second planet carrier 138.Jackshaft 160 and
Can be fixed together to use the mode such as screw or welding between two planet carriers 138, it would however also be possible to employ integrally
The mode of molding is fixed together.In this embodiment, between having between jackshaft 160 and spindle hole 146
Gap, such jackshaft 160 can rotate in spindle hole 146.In other embodiments, jackshaft 160
It is connected with being rotated by bearing between spindle hole 146, so that main shaft 140 rotation is more stable.
Casing 110 is additionally provided with fore bearing 142 and rear bearing 144.Fore bearing 142 is located close to chuck 150
Side and be supported on main shaft 140.Rear bearing 144 is positioned at distance chuck 150 in planetary gear mechanism
Between two groups of nearest epicyclic trains, and it is supported on jackshaft 160.It is to say, rear bearing 144
Between the second epicyclic train and first planet gear train.Concrete, the inner ring of fore bearing 142 is fixed
On main shaft 140, outer ring is fixed in casing 110.The inner ring of rear bearing 144 is fixed on jackshaft 160
On, outer ring is fixed in casing 110 by supporter 162, i.e. supporter 162 is fixed in casing 110,
The outer ring of rear bearing 144 is fixed on supporter 162.Certainly, the outer ring of rear bearing 144 can also herein
It is directly anchored in casing 110, the most only needs suitably to increase on jackshaft 160 and be connected with rear bearing 144
The diameter of part.When main shaft 140 rotates, fore bearing 142 and rear bearing 144 can play very well
Restriction effect.
Further, jackshaft 160 is provided with the gear teeth that the planetary gear with first planet gear train is meshed.
Second epicyclic train will by the gear teeth that planetary gear with first planet gear train on jackshaft 160 is meshed
Power passes to first planet gear train.It is to say, the second planet carrier 138 is by jackshaft 160
The gear teeth communicate rotational motion to the first row star-wheel 131.So, the power from motor 120 output just can depend on
Secondary reach main shaft 140 through third planet gear train, the second epicyclic train and first planet gear train.
Owing to fore bearing 142 is arranged close to the position of chuck 150, rear bearing 144 is positioned at the second planet tooth
Between train and first planet gear train, rear bearing 144 is supported on main shaft 140 indirectly by jackshaft 160
On, so just there being bigger distance between fore bearing 142 and rear bearing 144, main shaft 140 shakes when rotated
Dynamic the least.Owing to there being bigger distance between fore bearing 142 and rear bearing 144, the main shaft 140 when design
Length be just provided with the space of shortening.Although the length shortening main shaft 140 can cause fore bearing 142 with after
Distance Shortened between bearing 144, but due to the change of rear bearing 144 fixed position, relative to conventional
The mode that fore bearing and rear bearing are each attached on main shaft by drill kind tool, the fore bearing of this drill kind tool 100
Distance between 142 and rear bearing 144 does not shorten in the case of main shaft 140 shortens.And main shaft 140
Contraction in length, the length of this drill kind tool 100 just can shorten.So, this drill kind tool 100 can
With ensure main shaft 140 rock when rotating less on the premise of suitably shorten the length of main shaft 140, this brill class
The volume of instrument 100 the most just can reduce.
It addition, this drill kind tool 100 also includes limiting the spacing collar that fore bearing 142 slides along main shaft 140,
Can be provided with stopper slot on main shaft 140, spacing collar is fixed in stopper slot.Current bearing 142 is fixed on master
After on axle 140, it is possible to prevent fore bearing 142 to slide along main shaft 140 by spacing collar, so that main shaft 140
Stable rotation can be kept.
The rear bearing of this drill kind tool is between first planet gear train and the second epicyclic train and is supported on
On jackshaft, one end of jackshaft is arranged in the spindle hole of main shaft, and the other end passes first planet gear train,
And be fixed on the planet carrier of the second epicyclic train.So position of rear bearing is moved to motor direction, phase
By fore bearing and rear bearing, the mode on main shaft is all supported on respectively for conventional drill kind tool, this brill class
Instrument can shorten the length of main shaft ensureing main shaft in the case of the most acutely rocking when rotating, thus shorten and be somebody's turn to do
The length of drill kind tool, makes the advantage that this drill kind tool has small volume.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
