Abstract
The utility model discloses a chain grate speed-regulating box for a boiler, which is composed of a motor-power input shaft, a gear reduction mechanism, a worm gear for further speed reduction, etc., wherein, the power input shaft 1 is connected with a planetary speed reducer with few gear tooth differences composed of a wobble shaft 2, a planetary gear 3, a fixed ring gear 4 and a movable ring gear 5; a worm rotating shaft 6 is connected with a clutch 8 by keys and free sheathed with a secondary gear 9; a double gear of a duplicate gear 11 free sheathed on a middle shaft 10 is respectively engaged with a filtering gear 7 fixedly connected with the movable ring gear and the secondary gear 9. The utility model overcomes the defects of too many members, large noise and inconvenient maintenance in the prior art.
Description
The utility model belongs to boiler accessory machinery and makes the field.
Present boiler traveling-grate stoker governing box, (as LJ50 series) adopt multistage rotating shaft and multi-stage gear to slow down always, and complex structure, actuated element are many, and this makes that governing box is bulky, noise is high and production cost height, inconvenient maintenance.
The purpose of this utility model is a kind of boiler traveling-grate stoker governing box of design, makes it to overcome the above shortcoming of prior art, obtains bigger speed reducing ratio with less object, makes governing box compact conformation, easy to maintenance.
The purpose of this utility model is to realize by following design.
The boiler traveling-grate stoker governing box that the power output shaft of mainly being paid by the worm and gear of motor power power shaft, gear reduction and the usefulness of further slowing down and linking with worm gear etc. is formed, power input shaft and by eccentric shaft, planetary gear, fixedly the planetary speed reducer with small tooth number difference formed of ring gear and movable ring gear links; Key is connected with clutch in the worm screw rotating shaft, and is set with intermediate gear, two gears that a sky is enclosed within the duplicate gear on the jackshaft respectively with the transition gear and the intermediate gear engagement that connect firmly with movable ring gear.
After having adopted structure as above, realized quickly and easily that with a planet gear mechanism and speed change clutch big amplitude ratio tentatively slows down, element is few, compact conformation, production cost reduce relatively, and easy to maintenance, noise is low.
Description of drawings is as follows.
Fig. 1 is the mechanism map of the utility model embodiment.
Fig. 2 is the cutaway view of the utility model embodiment.
Below in conjunction with accompanying drawing the utility model is described in further detail.
In the drawings, motor is given power shaft 1 by belt pulley and clutch with transmission of power, the eccentric shaft 2 that links to each other with power shaft 1 with transmission of power to the planetary gear on it 3, planetary gear 3 is a duplex gear, wherein a tooth is fixedly revolving round the sun on the ring gear 4 under the effect of eccentric shaft, under the effect of fixing ring gear, whole planetary gear 3 is being made spinning motion around the axis of eccentric shaft again when ring gear is done revolution, and deceleration of motion is passed to movable ring gear 5.One end of worm screw rotating shaft 6 is slidably inserted in the transition gear 7 that connects firmly with ring gear 5, also has the clutch 8 that connects with it by key 12 in the rotating shaft 6, and the empty intermediate gear 9 that is enclosed within on the axle, jackshaft 10 connects firmly with casing, and two gears that a sky is enclosed within the duplicate gear 11 on the jackshaft 10 mesh with transition gear 7 and intermediate gear 9 respectively.Clutch 8 can slide in rotating shaft 6, when clutch mediates (position in as Fig. 2), drive intermediate gear 9 around the shaft 6 idle running by the rotation that transition gear 7 passes over by duplicate gear 11 by movable ring gear 5, the output speed of whole reduction box is zero; When clutch 8 slides to when fitting with transition gear 7, rotate and drive rotating shafts 6 by gear 7 and pay the rotation of transmitting to worm and gear with the transition gear same rotational speed; When clutch 8 slided to intermediate gear 9 applyings, the rotation of intermediate gear 9 was paid for low rotating speed passes to worm and gear than transition gear 7 intermediate gear by clutch 8, key 12, makes the more low rotation of passing on of reduction box output.
The utility model is reasonable in design, compact conformation, and volume is little, in light weight, stable working, noise is low, easy to maintenance, mechanical efficiency is high.The same with original type (LJ50) on installation dimension and important technological parameters, can with the whole exchange of original type.
Claims (1)
1, boiler traveling-grate stoker governing box, the power output shaft of mainly being paid by the worm and gear of motor power power shaft, gear reduction and the usefulness of further slowing down and linking with worm gear etc. is formed, it is characterized in that, power input shaft (1) with by eccentric shaft (2), planetary gear (3), fixedly the planetary speed reducer with small tooth number difference formed of ring gear (4) and movable ring gear (5) links; Worm screw rotating shaft (6) is gone up key and is connected with clutch (8), and is set with intermediate gear (9), and two gears that a sky is enclosed within the duplicate gear (11) on the jackshaft (10) mesh with the transition gear (7) and the intermediate gear (9) that connect firmly with movable ring gear (5) respectively.
