The utility model is characterized in that the extrusion-push type gear retarding mechanism is provided with a driving wheel, a driven wheel, a wedge, a power axle and an output axle, the driving wheel is arranged on the driven wheel, gears (bowl type gears) are respectively arranged on the opposite surface of the driving wheel and the driven wheel, the gears on the driving wheel are one more than the gears on the driven wheel, a positioning steel ball is arranged at the position of a wheel center between the driving wheel and the driven wheel, the wedge is connected at the end of the power axle, the inclined surface of the wedge is contacted and connected with the reverse side of the driving wheel, and the driven wheel is connected at the end of the output axle. Gear teeth on the driving wheel are involute teeth, gear teeth on the driven wheel are trapezoid teeth, and the center lines of the power axle and the output axle are identical. The utility model has the advantages that the structure is reasonable and simple, the manufacturing is easy, the cost is low, the transmission ratio is large, the transmission efficiency is high, and thus the utility model is suitable for the gearing down application of various machines.
Description
Technical field
The utility model relates to a kind of reducing gear, particularly utilizes the gear teeth to squeeze the structural type that pushes away transmission, belongs to the mechanical transmissioning technology field.
Background technique
Existing reducing gear generally adopts profile of tooth identical with modulus, the a pair of meshed transmission gear that the number of teeth is different, its velocity ratio can not be done too greatly, obtain big velocity ratio, need with two pairs to cog, therefore cause volume big, consumptive material is many, transmission efficiency is by degradation defective under the level, and the worm and gear transmission of the kind of drive of the big speed ratio of other form as generally adopting exists difficulty of processing big, the different axis with output shaft of transmission shaft, many defectives such as transmission efficiency is low are restricted its using scope.
The model utility content
The purpose of this utility model provides a kind of simple in structure, and velocity ratio is big, stable drive, and the gear teeth that transmission efficiency is high squeeze the pushing-type reducing gear.
The purpose of this utility model is to realize like this, the gear teeth squeeze the pushing-type reducing gear, it is characterized in that being provided with driving wheel, follower, wedge, line shaft, output shaft, driving wheel places on the follower, be respectively equipped with the gear teeth (benzvalene form gear) on the opposing side of driving wheel, follower, the gear teeth on the driving wheel are more than the gear teeth on the follower, core wheel place between the two-wheeled is provided with locking ball, wedge is connected the power axle head, the inclined-plane of wedge is connected with the contact of driving wheel back side face, and follower is connected the output axle head.
The gear teeth on the described follower lack a tooth than the gear teeth on the driving wheel.The gear teeth on the driving wheel are involute tooth.The gear teeth on the follower are stepped tooth.Line shaft is identical with the shaft axis of output shaft.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and velocity ratio is big, the transmission efficiency height.Line shaft by the dynamic power machine driving, the hard-wired wedge that has the inclined-plane of power axle head, the below of wedge is that flank profil is the driving wheel (benzvalene form gear) of involute, in the process of wedge with the line shaft motion, forces the gear teeth of driving wheel to move up and down by sinusoidal rule.The below of driving wheel is the few tooth of gear ratio driving wheel, modulus is slightly larger than driving wheel, flank profil is the follower (benzvalene form gear) of the stepped tooth of straight line, when the gear teeth of driving wheel from top to bottom move, progressively clamp-on follower, force follower to move to a side (reverse) with line shaft, the driving wheel periphery gear teeth transmit in turn, force follower to make circular movement around axis, the line shaft revolution moves a week, the driving wheel gear teeth by sinusoidal rule up and down once, follower rotates and is a circular pitch of driving wheel, because the driving wheel flank profil is a curve, process is again by sinusoidal rule continually varying up and down, therefore the process of driving wheel incision follower is steadily shock-free, again because the driving wheel number of teeth of this driving mechanism is exactly a velocity ratio, therefore velocity ratio can be bigger, only need a pair of gear just can realize big velocity ratio, the process of driving force is to go up wheel to squeeze the effect of wheel just as wedge of pushing, so transmission efficiency height of power, add driving shaft and output shaft coaxial line, easy to manufacture, accuracy of manufacturing and installation precision all are easy to be guaranteed.
