The utility model comprises a motor, a safety protecting device, a gear change mechanism and a three-stage retarding mechanism which is composed of two shafts, two dual-articulated gears and two gears, wherein, the transmission shaft of the three-stage retarding mechanism is connected with an eccentric shaft through gear transmission, and the eccentric shaft is sheathed with a dual articulated planet gear whose one gear is engaged with a fixed annular gear and the other gear is engaged with an annular gear fixed on an output shaft. The utility model has the advantages of reverse transmission, convenient maintenance, high efficiency, small noise and compact structure.
Description
The utility model relates to and a kind ofly is used for industrial boiler, oven, hardening furnace, annealing furnace chain type fire grate drags or metallurgy, mine, chemical industry, engineering machinery drags at a slow speed or lift by crane use variable speed drive more.
In the prior art, be used for variable speed drive that the chain type fire grate drags and be double-speed motor through one by two duplicate gears of two axles and two three grades of reducing gears that gear constitutes, mesh by triple gear and three gear changes on another through one again, the worm shaft that links is then exported through the worm and worm gear back of slowing down.Adopt this transmission device, broken down when dragging part, block as fire grate, when needing maintenance, because the worm gear pairs self-locking, motor can not reverse, and must stop machine operation, oppositely drags maintenance by artificial afterburning worm shaft counter-rotating; And, make the transmission device total efficiency low, and noise is big because the worm gear pairs transmission efficiency is low.
The purpose of this utility model be to provide a kind of can reverse transmission so that by drag part troubleshooting, transmission efficiency height and rotational noise less use variable speed drive more.
For achieving the above object, the utility model adopts following technical proposals: these are many to include motor, safety protection device, gear and by two duplicate gears of two axles and two three grades of reducing gears that gear constitutes with variable speed drive is the same with prior art.Be characterized in: the transmission shaft of three grades of reducing gears is by the gear transmission eccentric shaft that links, compound planet gear of suit on the eccentric shaft; A gear and a fixing internal gear engagement of this compound planet gear, and its another gear and an internal gear engagement of being fixed in output shaft.Like this, this transmission device adopts tertiary gear reducing gear and fewer differential teeth planetary decelerator structure, and does not adopt the worm and worm gear reducing gear, thereby overcomes shortcoming existing and that technology exists.
The utility model compared with prior art, has conspicuous advantage: make up driving mechanism because the utility model adopts tertiary gear to slow down and fewer differential teeth planetary slows down, and do not adopt the worm and worm gear reducing gear, when being needed maintenance dragging that part is out of order, can make the motor counter-rotating and realize reversing drive, make to be dragged part and oppositely drag, with convenient maintenance; The utility model transmission efficiency is higher, and rotational noise is less, compact structure.
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is a transmission system simplified schematic diagram embodiment illustrated in fig. 1.
Fig. 3 be among Fig. 1 K to partial enlarged drawing.
Fig. 4 is another embodiment's of the utility model a transmission system simplified schematic diagram.
Fig. 5 is the transmission system simplified schematic diagram of transmission device in the prior art.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, motor 31 adopts double-speed motor, through the input shaft 27 of belt and three grades of reducing gears of pulley mechanism 30 interlocks.Three grades of reducing gears are made of 20,21,28,29 and two gears of 27,13, two duplicate gears of two axles 19,29.Have spline to cooperate with a triple gear 14,16,17 sliding sleeves on the transmission shaft 13 of three grades of reducing gears, three gears 14,16,17 of this triple gear and three gears, 12,15,18 conversion that are fixed on an eccentric shaft 6 inner prolongation axles 1 are meshed.Compound planet gear of suit 9,10 on the eccentric shaft 6; A gear 10 and fixing internal gear 11 engagements of this compound planet gear, and its another gear 9 and internal gear 8 engagements of being fixed in output shaft 4.Referring to Fig. 3, shift level 30 is equipped with in the top of transmission device case 5, and it is connected shifting block 35 through rotating shaft 33 with connecting rod 34, shifting block 35 interlock triple gears 14,16,17.So swing shift level 30 can make triple gear displacement conversion its with the gear of three gears 12,15,18, the transmission of formation third gear different drive ratios; Again because of adopting double-speed motor 31, thereby constitute the transmission of big shelves different rotating speeds.Referring to Fig. 1; between belt and pulley mechanism 30 and three grades of reducing gears safety protection device is housed; its structure is: the spring 24 of being adjusted spring force by bolt 22 nuts 23 is housed on the transmission pulley; the interior end bearing of spring 24 steel ball 25, and steel ball 25 bottoms place in the ball hole of being fixed in the collar 26 on three grades of reducing gear output shafts 27.When being dragged part when blocking, the mechanism of gear reduction part blocks and can not rotate, and then steel ball 25 overcomes the constraint of spring force and skids off the ball hole, so motor 31 is rotated further and can not damages transmission device.Referring to Fig. 1, output shaft 4 is connected with the rotating shaft 2 that is dragged part by coupling 3.Internal gear 8 is fixedlyed connected with output shaft 4 by dish 7.
Another embodiment of the present utility model is: referring to Fig. 4, the structure of the present embodiment structure with the foregoing description basically is identical, difference only is that its gear is: motor 31 adopts stepless speed regulation motor, through the input shaft 27 of belt and three grades of reducing gears of pulley mechanism 30 interlocks; Gear 14 on the transmission shaft 13 of three grades of reducing gears and gears 12 engagements that are fixed on the eccentric shaft 6 inner prolongation axles 1.Realize the stepless change transmission of transmission device by stepless speed regulation motor.
