The time for regulating the side gap between the gears is saved, and the work efficiency is improved.
Description
Technical field
The utility model relates to the gear transmission sideshake and eliminates mechanism, is specifically related to elimination mechanism of transmission side clearance of cylindrical gear with linear movement.
Background technique
At present, the reduction gear in the dynamoelectric equipment feeding system also need be eliminated the drive gap between driving gear pair as far as possible except exigent kinematic accuracy own and stable working.Otherwise gear backlash can cause the each repercussion motion delay of feeding system in command signal, loses command pulse and produces reverse dead band, and is very big to the transmission accuracy influence.At present, the method for elimination gear backlash says that on principle can be divided into static the adjustment reaches two kinds of dynamically adjustment.One, the static adjustment mainly comprises: eccentric bushing adjustment and the adjustment of bidentate wheel side set.The eccentric bushing adjustment as shown in Figure 2, motor installs on the housing by eccentric bushing, thereby eliminates gear backlash by the centre distance that rotating eccentric sleeve just can be adjusted two gears.Bidentate is taken turns the side set adjustment as shown in Figure 3, two web gear 1,2 and engagements of another one wide gears that the number of teeth is identical.Web gear 1,2 is sleeved on together, and can do relative rotation motion.Have circumferential arc groove on each web gear and press-fited spring lug 3,4 in the groove of gear 1,2, because the effect of spring 6 makes gear 1,2 dislocation, the teeth groove left and right side with wide gear is adjacent to respectively, thereby eliminates gear backlash.Yet static adjusting method can not accomplish to eliminate in real time gear backlash, therefore is not suitable for being applied in the model in wind tunnel unwheeling.Two, dynamically adjustment mainly comprises: the extension spring side set is adjusted and stage clip changes the centre tooth adjustment.The adjustment of stage clip side set is processed into 1 and 2 two-part with bevel gear wheel as shown in Figure 4, and the outer ring 1 of gear has three arc grooves 8.The end face of inner ring 2 has three dogs 4, is sleeved in the arc groove.The two ends of spring 6 withstand on dog 4 respectively and insert on 7, make the awl tooth dislocation of Internal and external cycle 1,2 and bevel pinion engagement reach the effect of eliminating the gap.Stage clip changes the centre tooth adjustment as shown in Figure 5, and bevel gear 1,2 is meshing with each other.On the axle 5 of bevel gear 1, stage clip 3 is housed, adjusts the elastic force of stage clip 3 with nut 4.Bevel gear 1 moves axially in the effect lower edge of elastic force, can eliminate the gap of bevel gear 1 and 2.Though yet above-mentioned dynamic adjusting method can realize eliminating in real time gear backlash, its structure characteristic be not suitable for using and move in the model in wind tunnel unwheeling on.
The model utility content
The utility model exists sideshake to cause the feeding system reversing motion to lag behind command signal when having elimination gear backlash method now in order to solve, lose command pulse and produce reverse dead band, thereby reduced gear-driven precision, can not accomplish to eliminate in real time gear backlash, normally carrying out of influence test, inefficiency, though dynamic adjusting method can realize eliminating in real time gear backlash, but its structure be not suitable for using and move in the model in wind tunnel unwheeling on problem, a kind of elimination mechanism of transmission side clearance of cylindrical gear with linear movement is provided, and the concrete technological scheme that addresses the above problem is as follows:
A kind of elimination mechanism of transmission side clearance of cylindrical gear with linear movement of the present utility model, by gearwheel, small gear, connecting frame, mounting base, sliding rail, leading screw, stage clip, retarder and motor are formed, framework is located on the retarder, mounting base is located at the right-hand member of connecting frame, sliding rail and stage clip are located on the mounting base, leading screw is located between connecting frame and the stage clip, the left end of sliding rail is connected with connecting frame, the left end of leading screw is fixed on the connecting frame, the right-hand member of leading screw is connected with stage clip, connecting frame is fixedlyed connected with retarder, and small gear is connected with retarder, and retarder is connected with the output shaft of motor.
Elimination mechanism of transmission side clearance of cylindrical gear with linear movement of the present utility model, this mechanism can effectively eliminate gear backlash constantly under static state and dynamical state, solution is lagged behind command signal, loses command pulse and is produced the problem in reverse dead band by the feeding system reversing motion that sideshake causes, this mechanism can save the time of adjusting sideshake between gear greatly, improved working efficiency, significant for eliminating the gap between gear pair in real time, its application prospect is very wide.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is that eccentric bushing is adjusted the sideshake schematic representation, and Fig. 3 is that bidentate wheel side set is adjusted the sideshake schematic representation, and Fig. 4 is that the stage clip side set is adjusted the sideshake schematic representation, and Fig. 5 is that stage clip change centre tooth is adjusted the sideshake schematic representation.
Embodiment
Embodiment one: describe present embodiment in conjunction with Fig. 1.Present embodiment is by gearwheel 1, small gear 2, connecting frame 3, mounting base 4, sliding rail 5, leading screw 6, stage clip 7, retarder 8 and motor 9 are formed, framework 3 is located on the retarder 8, mounting base 4 is located at the right-hand member of connecting frame 3, sliding rail 5 and stage clip 7 are located on the mounting base 4, leading screw 6 is located between connecting frame 3 and the stage clip 7, the left end of sliding rail 5 is connected with connecting frame 3, the left end of leading screw 6 is fixed on the connecting frame 3, the right-hand member of leading screw 6 is connected with the left end of stage clip 7, connecting frame 3 is fixedlyed connected with retarder 8, small gear 2 is connected with retarder 8, and retarder 8 is connected with the output shaft of motor 9.
When gearwheel 1 and small gear 2 produce drive gap in the course of the work, being that the connecting frame 3 of one is stressed with small gear 2, retarder 8 and motor 9 moves to the right, the leading screw 6 that is fixed on the connecting frame 3 acts on the active force of connecting frame 3 sideshake that produces on the stage clip 7 that is installed on the mounting base 4 simultaneously, stage clip 7 provides the reaction force of corresponding horizontal direction, and can effectively eliminate the sideshake that produces between gearwheel 1 and the small gear 2 under static state and the dynamic state at any time.
