Abstract

A portable power tool has bevel gearing which allows a rotational position between a drive shaft 13 and an output shaft 35 of 0 to 90{. For this purpose, a drive housing 15 and an output housing 37 in which the respective shafts 13, 35 are rotatably mounted can be mutually rotated in a rotational plane 44. The bevel gearing has an intermediate gear 26 on which two sets of conical teeth 30, 31 are integrally formed and which is mounted on a free end 25b of a bolt 23. The bolt 23 is pressed into a receiving bore 24 in the drive housing 15 which encloses an angle of about 45{ with an axis of rotation 22 of the driving shaft 13.

Description

Electric hand tool with bevel gearing
The present invention relates to a kind of electric hand tool with bevel gearing.
WO-A-92/20491 discloses the electric hand tool of this type, and the cogged jackshaft in two ends is housed on its transmission device.Because have few component parts.The cost of making its transmission device of assembling is higher.Jackshaft two ends cogged and bearing structure placed in the middle has strengthened the space that occupies is arranged again.
According to the electric hand tool with bevel gearing of the present invention, power transmission shaft with CD-ROM drive motor, described cardan-shaft suspension is on the transmission casing, sidepiece swivel bearing another power transmission shaft on a transmission housing is by bevel gearing and power transmission shaft coupling, bevel gearing has two bevel gear levels for this reason, described transmission casing and transmission housing can relatively rotate at a rotational plane, this plane and described two power transmission shafts angle at 45, described bevel gearing has a transition wheel, two bevel gears are arranged thereon, one side meshes with the bevel pinion that rotation is fixed on the power transmission shaft, be fixed on the angular wheel engagement of the plate-like wheel on another power transmission shaft on the other hand with rotation, described transition wheel swivel bearing is on one, one end of described axle is fixed in the transmission casing, and described transition wheel is bearing on the free end of described axle.
Compare with disclosed technical scheme in the documents, according to the advantage of electric hand tool of the present invention be, the manufacturing assembly fee that has simplified the structure, reduced bevel gearing is used.In addition, because the distance between axles of bevel gearing engagement is reduced to minimum degree, the space that its transmission device is occupied reduces, thereby also reduce the volume of electric hand tool, further improved owing to the narrow situation of applicability, particularly working space that adopts bevel gearing to increase.
Accompanying drawing shows one embodiment of the present of invention, will be set forth hereinafter:
Bevel gearing longitudinal sectional drawing when Fig. 1 is 90 ° of borings of electric hand tool corner;
Bevel gearing longitudinal sectional drawing when Fig. 2 is 0 ° of straight line boring.
The bevel gearing label is 10 among Fig. 1, is contained on the electric hand tool of rotation driving.The disclosed electric hand drill of the similar substantially WO-A-92/20491 of the main structure of electric hand tool, all disclosed purposes of electric hand tool are seen its specification.
Part shows handheld electric tool machine shell 11 and the CD-ROM drive motor 12 that is contained in its housing among Fig. 1.Electric hand tool can be done the work of various rotations as boring, tightens up a screw mill, brush.
Bevel gearing 10 is contained on the handheld electric tool machine shell 11, becomes one with it.Bevel gearing 10 is equipped with power transmission shaft 13, is the motor shaft of motor 12 in this example, and it is contained on the transmission casing 15 rotationally by its bearing 14, and power transmission shaft 13 rotatably is equipped with bevel gear 16, and with spindle nut 17 axial fastenings, it is not moved axially.Axle 20 acutangulates with power transmission shaft 13 and is installed in the transmission casing 15.In the present embodiment, the axial line 21 of axle 20 is 45 ° with axial line 22 angles of power transmission shaft 13, axle 20 is a pin rod 23, an its end 25a is force-fitted in the installing hole 24 of transmission casing 15, half of pin rod 23 length exposed installing hole 24, promptly form free end 25b, it is that its swivel bearing is on the bearing on the axle 20 28,29 on the free end 25b of axle 20 that transition wheel 26 is enclosed within pin rod 23.In the other embodiments, available part is screwed into the fitted bolt of transmission casing 15 and makes axle 20.
Two bevel gears 30,31 are arranged on the transition wheel 26, and the three is one in fact.Its transition wheel is actual in taking turns plate-like, first bevel gear, 30 engagement bevel gears 16 on it, and the angular wheel 31 on transition wheel 26 first angular wheels 30 opposites is taken turns 34 angular wheel 34a engagement as bevel drive pinion with plate-like, and plate-like wheel 34 is fixed on the power transmission shaft 35.Transition wheel 26 preferably can with technology chipless such as sintering make.The tool chuck that omits on the working end installation diagram of driven shaft 45 is with civilian dress drill bit, screw tool, grinder tool and steel brush etc.
The first angular wheel level 18, second bevel gear 31 that the taper pinion 16 and first bevel gear 30 are formed bevel gearing 10 constitute bevel gearing 10 second angular wheel levels 19 with plate-like wheel 34.
Power transmission shaft 35 by supporting arrangement be bearing 36 with respect to transmission housing 37 swivel bearings, transmission casing 15 connects with transmission housing 37 in the mode of bayonet socket or rotation.There is one to have the radially wheel rim 40 of annular groove 41 on the transmission casing 15.The projection 42 that inwardly turn in the footpath on the transmission housing 37 steadily is stuck in the annular groove 41, transmission housing 37 can be rotated but relative to transmission casing 15 can not do axially-movable.Transmission housing 7 is the 45 ° left and right sides angles of cut perpendicular to the longitudinal axis 21 of axle 20 with the rotating shaft 45 of power transmission shaft 35 relative to the rotational plane 44 that transmission casing 15 rotates.Corner between the rotating shaft 22,45 of power transmission shaft 13 and power transmission shaft 35 can reach about 90 ° at the position of rotation of as shown in Figure 1 transmission housing 37.
37 of transmission casing 15 and transmission housings have a locking device 48, with it transmission housing 37 and transmission casing 15 are locked in the corner position that needs, and for this reason, have a plurality of lock holes 49 (can simultaneously referring to Fig. 2) on transmission housing 37.Locking tightening latch 50 by spring 51 precompressed is locked in its hole 49.Wrench 52 is used for antagonistic spring 51 elastic force from lock hole 49 withdrawal locking select bars 50, and transmission housing 37 can be rotated relative to transmission casing 15.The lock hole 49 that distributes on circumference is many more, and the turned position of alternative transmission housing 37 is many more.
Among Fig. 2, do 180 ° of angles with respect to the transmission housing 37 of Fig. 1 bevel gearing 10 relative to transmission casing 15 and rotate.The axis 45 of power transmission shaft 35 is at this moment parallel with the axis 22 of power transmission shaft 13 but do not overlap.From this position,, can make the stepless adjustment between 0 ° to 90 ° of its corner by the rotation of transmission casing.Connect various tool on the power transmission shaft 35, can use electric hand tool as, carry out various operations in general inaccessible operating position with different corners.Locking depends on the lock hole 49 of circle distribution.
The present invention is not limited to above embodiment, can adopt other power source such as air motor etc. as CD-ROM drive motor 12.Bevel gearing also can be used as attachment device and is contained on the electric hand tool, becomes independently unit.
