Description

The semimounted multiple spot engagement flexible gearing of sintering machine

The utility model belongs to mechanical transmission fields, is a kind of semimounted multiple spot engagement flexible gearing of sintering machine.

At present, the transmission device of sintering machine mostly is the flexible kind of drive of semimounted.It mainly is made up of triple reduction gear, wherein the final stage retarder is made up of left and right two small gears that are connected the gearwheel on the sintering machine head star gear shaft and be engaged with, and each small gear is driven by the speed reducer that a middle worm type of reduction gearing and elementary retarder are formed respectively.The bearing support and the intermediate gearbox of above-mentioned small gear combine as a whole rigidly, form a gear frame, left and right gear frame links up with pull bar again, make the engagement of small gear and gearwheel, constitute flexible structure, and be suspended on the sintering machine star gear shaft, and elementary retarder is suspended on the worm shaft of intergrade retarder.This transmission device is owing to be provided with two cover intergrade worm type of reduction gearings, thereby manufacturing and Installation and Debugging difficulty not only, and transmission efficiency is lower, and working life is shorter.

The purpose of this utility model provides a kind of semimounted multiple spot engagement flexible gearing of simple in structure, sintering machine that transmission efficiency is higher.

The solution that realizes the utility model purpose is: the sintering machine semimounted flexible gearing that is provided comprises one by being connected the final stage retarder that gearwheel on the sintering machine head star gear shaft and at least two small gears that are engaged on this gearwheel left and right sides constitute and the elementary retarder of driving pinion, wherein the left and right sides small gear of final stage retarder is installed on separately the bearing support, be united together with pull bar between the bearing support of each lateral denticle wheel, and be suspended on the sintering machine head star gear shaft.Improvements of the present utility model are the pinion shaft connection of the output terminal of described elementary retarder by universal-joint spindle and final stage retarder, roller also is housed on the bearing support of each small gear, this roller contacts with the circular track wheel of final stage retarder gearwheel end, the position of roller is positioned at the top of this gearwheel horizontal diameter, the bearing support of each small gear is connected with the basis with horizontal torsion bar by vertical strut and tie, wherein the upper end of strut and tie links to each other with the small gear bearing support, the lower end links to each other with horizontal torsion bar, and horizontal torsion bar is installed on the basis.Like this, whole transmission device just is in half suspended state, and wherein set pair of rollers final stage small gear plays the positioning action on the vertical direction.

Size according to output torque and space, final stage transmission of the present utility model can be adopted 2 points, or six point gearing modes at 4, but be best in two point gearing modes generally speaking, promptly the small gear of final stage retarder has two, and they are symmetrically distributed in the both sides of gearwheel.

Compared with prior art, the utility model has saved the Worm and worm-wheel gearing of intergrade, and structure is greatly simplified, and manufacturing expense reduces, and transmission efficiency also is greatly improved.Install simultaneously, debug and keep in repair also more convenient, working life also corresponding being improved.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is the structural representation of the utility model most preferred embodiment.

Fig. 2 is the concrete structure figure of Fig. 1.

Fig. 3 is the partial view that roller cooperates with gearwheel among Fig. 2.

Fig. 4 is the partial view that small gear cooperates with gearwheel among Fig. 2.

As shown in Figure 1 and Figure 2: this transmission device adopts two point gearing modes, on the star gear shaft 1 of sintering machine head final stage gearwheel 2 is housed, and the both sides of gearwheel 2 horizontal diameter directions respectively have small gear 3a, a 3b to be engaged with.Be associated in together with upper and lower two pull bar 5a, 5b between bearing support 4a, the 4b of two small gears, and be suspended on the sintering machine star gear shaft 1 by gearwheel 2.Roller 6a, a 6b respectively are housed on small gear bearing support 4a, the 4b, and they place on the rail wheel 7 of gearwheel 2 ends, make small gear 3a, 3b be unlikely to throw off with gearwheel 2, and its structure as shown in Figure 3.In order further to guarantee the good engagement of small gear and gearwheel, also be provided with a limited wheel 3c coaxial in the end of small gear 3a, 3b with small gear, this limited wheel also contacts with the rail wheel 7 of gearwheel end, and its structure is as shown in Figure 4.In addition, bearing support 4a, the 4b of small gear links to each other with the basis with torsion bar 9 by strut and tie 8a, 8b again, and wherein the lower end of two stayed mast 8a, 8b is connected with homonymy support arm 10a, the 10b of torsion bar 9.When two small gears drove gearwheel, two strut and tie 8a, 8b will bear pulling force or pressure respectively, and this draws, pressure just is delivered on the torsion bar 9 by support arm 10a, 10b, thereby has guaranteed the stability of transmission device.Above-mentioned final stage small gear is driven through elementary planetary reducer 12 and universal-joint spindle 13 by motor 11, and retarder 12 is installed on the basis with motor 11.

The utility model is not limited to the transmission of sintering machine, also can be used for the transmission of other low-speed big.
