The invention solves the problems that the side clearance lowers the transmission accuracy of the gear, the side clearance of the gear can not be eliminated at real time, and the working efficiency is low. In the invention, a connection frame is arranged on a speed reducer, an installation base is arranged at the right end of the connection frame, a slide track and a compression spring are arranged on the installation base, a lead screw is arranged between the connection frame and the compression spring, the left end of the lead screw is fixed on the connection frame, the right end of the lead screw is connected with the compression spring, and the connection frame is fixedly connected with the speed reducer. The invention can effectively eliminate the side clearance of the gear at real time in a static state and a dynamic state and solve the problems that the reverse movement of a feeding system is lagged behind a command signal because of the side clearance, a command pulse is lost and a reverse dead area is generated. The mechanism saves the time of regulating a side clearance between gears and enhances the working efficiency.
Description
Technical field
The present invention relates to the gear transmission sideshake and eliminate mechanism, be 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.
Summary of the invention
The present invention 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 invention, 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 invention, 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.
