Background technology
Along with the Safety of Coal Mine Production requirement is more and more higher, the colliery extensively adopts electric coal drill boring more and more to be restricted before.Because electric coal drill easily causes mistake quick-fried, electric leakage causes mine safety accidents, so require to adopt the pneumatic rotary rig to come bore operation.At present, the pneumatic rotary rig that uses in the colliery mainly adopts the monomer rotary structure, and its power slew gear is made up of the motor and the deceleration device of rotation at a high speed, and the employing secondary high transmission ratio that deceleration device has is paid to low auxiliary gear deceleration transmission from height.The shortcoming of the rig of this structure is that volume is big, Heavy Weight, Transmission bearing are low, and can not bore than hard rock.
Summary of the invention
Given this, the object of the present invention is to provide that a kind of volume is little, in light weight, Transmission bearing is high, and the hand-held pneumatic rotary-percussion boring machine with jerk structure.
In order to achieve the above object, the objective of the invention is to be achieved through the following technical solutions: this kind hand-held pneumatic rotary-percussion boring machine, comprise protecgulum, motor shell, gland, bonnet, be installed in the driving shaft in the motor shell, driven shaft, bearing is installed on driving shaft successively, motor gear, bearing, bearing is installed on driven shaft successively, needle bearing, motor gear, motor gear on the driving shaft is meshed with motor gear on the driven shaft, the jerk device wherein is installed in the protecgulum, it comprises the output gear cover, the fixed teeth cover, the vibrations spring, vibrations tooth cover, bearing, back-up ring, bore the tail card, end cap, output shaft, the output gear cover adopts splined or other key on driven shaft, and with the output shaft thread connection, the fixed teeth cover is installed on output shaft successively, vibrations tooth cover, bearing, back-up ring, end cap, bore the tail card, described fixed teeth cover is meshed with vibrations tooth cover and the vibrations spring is installed between them, vibrations tooth cover and output shaft loose fit can slide vertically.The rear end of driving shaft is provided with pinion, and this pinion can be to process on the axle of driving shaft rear end, also can be pinion part independently, be fixedly mounted on the driving shaft, the rear end of driven shaft is equipped with travelling gear, and pinion is meshed with travelling gear, forms the one-level deceleration transmission.
Described fixed teeth cover adopts welding to connect with output shaft.
The present invention has the following advantages: owing to adopted above-mentioned drive mechanism, can utilize driven shaft to drive the rotation of fixed gear cover, the fixed teeth cover is meshed with vibrations tooth cover on the output shaft, vibrations tooth cover is produced to be moved axially, under the vibrations spring drives, reset, move back and forth like this, output revolution ballistic motion, can reduce the workman like this and operate labour intensity, increase work efficiency, simultaneously its structure has also been simplified greatly, makes smaller volume, light weight, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, the present invention includes protecgulum 7, motor shell 22, gland 23, bonnet 1, be installed in the driving shaft 2 in the motor shell 22, driven shaft 18, bearing 6 is installed on driving shaft 2 successively, motor gear 4, bearing 3, bearing 19 is installed on driven shaft 18 successively, needle bearing 21, motor gear 20, motor gear 4 on the driving shaft 2 is meshed with motor gear 20 on the driven shaft 18, wherein in the protecgulum 7 jerk device 17 is installed, it comprises output gear cover 8, fixed teeth cover 9, vibrations spring 10, vibrations tooth cover 11, bearing 12, back-up ring 13, bore tail card 14, end cap 15, output shaft 16, output gear cover 8 adopts splined on driven shaft 18, with output shaft 16 thread connection, fixed teeth cover 9 is installed on output shaft 16 successively, vibrations tooth cover 11, bearing 12, back-up ring 13, end cap 15, bore tail card 14, described fixed teeth cover 9 is meshed with vibrations tooth cover 11 and vibrations spring 10 is installed between them.Fixed teeth cover 9 adopts welding to connect with output shaft 16, and vibrations tooth cover 11 and output shaft 16 loose fits can slide vertically.The rear end of driving shaft 2 is provided with pinion 5, and this pinion 5 can be to process on the axle of driving shaft rear end, also can be pinion part independently, is fixedly mounted on the driving shaft.The rear end of driven shaft 18 is equipped with travelling gear 24, and pinion 5 is meshed with travelling gear 24, forms the one-level deceleration transmission.
During work, the power source compressed air by the external world enters motor shell 22, promotes motor gear 4 and motor gear 20 rotates.Because motor gear 4 is to be installed in driving shaft 2 by key, the rotation of motor gear 4 will drive the rotation of driving shaft 2, and pinion 5 is with driving shaft 2 one or is fixedly mounted on the driving shaft 2 that therefore, the rotation of motor gear 4 will drive pinion 5 and rotate.Pinion 5 overlaps 11 by the fixed teeth that travelling gear 24, driven shaft 18, output gear cover 8 drive on the output shaft 16 then, and fixed teeth cover 9 overlaps 11 by engagement vibrations tooth, and its generation is endwisely slipped.By resetting under 10 effects of vibrations spring, can produce reciprocating motion so then, make output shaft 16 produce the revolution ballistic motion.
