Description
Technical field
The utility model relates to a kind of mining reduction box with vibratory impulse function, is applicable to mining each money pneumatic rotary churn, after being connected with the air motor matching, forms pneumatic drilling machine power output assembly.
Background technology
At present, the pneumatic drilling machine using in existing coal mine roadway mainly contains pneumatic rotary churn and air drill.Because air drill speed of gyration is slow, a little less than row's powder ability, when impact, easily produce spark, when running into coal seam, forbids industry requirement to use hammer drill.Pneumatic rotary churn is adapted at carrying out drilling deep hole in coal seam, while still running into dirt band, rock, a little less than rock breaking capacity, there will be brill motionless.Given this, need to design a kind of deceleration device that is different from hammer drill impact structure, when having decelerating effect, this device there is again the function of impact shock, be equipped with after rational air motor, make pneumatic drilling machine possess original pneumatic rotary churn high pulling torque, high-revolving advantage, there is again the ability of impact shock, and then improve operating efficiency and the scope of application of pneumatic drilling machine.
Summary of the invention
The purpose of this utility model is to provide a kind of deceleration device with impact structure, has again the impact shock structure that is different from hammer drill when this device has decelerating effect.
The purpose of this utility model is achieved in that vibration tooth cover and output shaft is assembled into and is tightened to one composition with holding screw after one and vibrates output shaft, vibration tooth cover and output shaft are by spline fitted, and vibrate tooth cover circumference has 4 screwed holes to be used for penetrating holding screw simultaneously.In shell of reduction box, first pack a bearing outside into, then fixed teeth cover and shell of reduction box are assembled into after one and hold out against with holding screw, fixed teeth cover has a draw-in groove, has a screwed hole for penetrating holding screw on reduction box casing, and screw thread fastening glue is smeared on holding screw surface.
Mechanical reduction gear is made up of output shaft, bearing, one-level driven gear, secondary driving gear shaft, secondary driven gear, reduction box casing, bolt assembly, gland, base plate, holding screw etc., mechanical reduction gear and common secondary gear reduction box are similar, and vibration generating apparatus forms by vibrating tooth cover, fixed teeth cover, vibrocompression spring, holding screw.
Vibration tooth cover is a circle vibration tooth with fixed teeth cover mating surface, between vibration tooth cover and fixed teeth cover, assemble vibrocompression spring, the vibration tooth that the elastic force of dependence vibrocompression spring and two teeth put cross arrangement produces upper and lower vibratory impulse rotating simultaneously.
The utility model is arranged on air motor, plays on the one hand the effect that reduces rotating speed increase moment of torsion, makes on the other hand output have the function of impact shock, increases rock breaking capacity, increases work efficiency.Compare the vibration-damper structure of hammer drill, newly-designed vibratory impulse structure is saved more than 80% than the vibratory impulse structure of hammer drill manufacturing cost, say from use angle, there is not the problem that cannot use after cylinder body wearing and tearing, after wearing and tearing, only need to change vibration component, complete machine extends application life greatly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
Detailed description of the invention
As shown in Figure 1, the main assembling process of the mining reduction box with vibratory impulse function of the present utility model is as follows: first reduction box casing 2 packs the overcoat of bearing 6 into, after putting in place by forcing press compression, pack fixed teeth cover 7 into, and hold out against with holding screw 15 in the screens groove of fixed teeth cover 7, screw thread fastening glue will be smeared in holding screw 15 surfaces, and forcing press is pressed into bearing 5 afterwards, is press-fit into place.Vibration tooth cover 9 is assembled on output shaft 12, and holds out against output shaft 12 with holding screw 14, screw thread fastening glue will be smeared in holding screw 14 surfaces, and the inner ring of bearing 6 is pressed on output shaft.Before vibrocompression spring 8 is put into, in ready shell of reduction box 2, vibrocompression spring 8 one end faces will be put into the circular groove of fixed teeth cover 7, so that location.The output shaft 12 assembling before packing into, the other end of vibrocompression spring 8 is put in the circular groove of vibration tooth cover 9, pack bearing 10 into, and be pressed into slightly in shell of reduction box 2, gland 13 is packed in shell of reduction box 2, aim at eyelet, pack bolt assembly 11 into, after putting in place by forcing press compression, the assembly 11 of bolting on.In the reduction box assembling before secondary driving gear shaft 4 is pressed into, be pressed into successively secondary driven gear 16, one-level driven gear 3, bearing 17, last mounting bedplate 1.In the time that reduction box is normally worked, utilize the intermeshing of profile of tooth between vibration tooth cover 9 and fixed teeth cover 7 and the elastic force that produces with the vibrocompression spring 8 of tooth inner room at the rotating vibrating function of realizing simultaneously.In the time that propulsive force is not enough to overcome the elastic force of vibrocompression spring 8, reduction box is the same with reduction box, only has deceleration.In the time that thrust is greater than the elastic force of vibrocompression spring 8, vibrocompression spring 8 compresses, and the engagement of upper and lower two teeth cover, simultaneously because reduction box continues revolution, makes upper and lower two teeth cover constantly between tooth and tooth, carry out bob, has now just realized vibratory impulse.Because amplitude is little, ballistic work is also little, does not have pyrophoric behavio(u)r occur through many experiments simultaneously.Vibration component all adopts low-carbon alloy steel, has hard and wear-resisting surface and tough and tensile core after nitrogencase hardening, has higher impact toughness, can effectively ensure the application life of product.
Reduction box of the present utility model can directly be used in combination with air motor, makes air motor output shaft aim at the centre bore of base plate 1, requires the profile of tooth that ensures air motor output shaft and reduction box one-level driven gear 3 to coincide simultaneously.When use, ensure that the flange of air motor output is consistent with the connection dimension of reduction box casing 2, then penetrate connecting bolt and just air motor and reduction box casing 2 can be linked into an integrated entity, form pneumatic rotary vibratory impulse churn.Also can not use base plate 1, air motor output end face be made to the profile joint face matching with reduction box casing 2, directly connect.
