The gear body of the runway type gear is connected with a guide slot plate, and the guide slot of the guide slot plate is matched with the guide axis section of the gear axle of the cylindrical gear, so that the gears are engaged with each other during the overall process of motion. A frame is provided with a spacing member which is used for limiting the plane motion of the guide slot plate. The runway type gear mechanism can implement the motion conversion of the rotation and movement of driving members and driven members. The runway type gear mechanism can be used for crank link mechanisms. The runway type gear mechanism has the advantage of high mechanical efficiency.
Description
The utility model relates to the gear mechanism in the mechanical transmission, and concrete is a kind of racetrack gear mechanism.
In mechanical transmission, often run into and need to realize rotate the conversion of moving or the conversion of rotation and oscillating motion with straight line, there be slidercrank mechanism (rotation-straight line moves) and the crankrocker mechanism (rotation-fan-shaped swing) in the quadratic crank mechanism in alternative mechanism, the common issue with that these two kinds of mechanisms exist is that the thrust between the crank-connecting rod is relevant with the angle between the crank-connecting rod, thrust maximum when crank becomes 90 degree angles with connecting rod, thrust is zero when crank and connecting rod conllinear, and in whole motion process, the mutually perpendicular time is shorter, thereby overall efficiency is not high.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of driving mechanism that improves structure is provided, and when achieving the conversion of rotation-mobile or mobile-rotation, mechanical efficiency improves.
Used technological scheme, a kind of racetrack gear mechanism of the present utility model is made up of a cylindrical gears and a racetrack gear, it is characterized in that:
A. cylindrical gears is a fixed axis gear, and the shaft part for the guide groove guiding is arranged on its gear shaft:
B. the racetrack gear is by two arc sections and two tangent continuous noncircular gears of the peripheral gear teeth that constitute gear teeth reticule of straightway;
C. connecting the guide channel plate that annular guide channel is arranged on the racetrack gear mass, the gear teeth reticule of this guide groove center line and cylindrical gears is equidistant, and its distance equals the reference radius of cylindrical gears, and the guide groove width matches with the guide section diameter of axle of cylindrical gears wheel shaft;
D. frame is provided with the bounding means that the restriction guide channel plate is done plane motion.
In preferred embodiment, two arc section equal diameters of the formation gear teeth reticule of described racetrack gear, two straightways are parallel.
Described restriction guide channel plate is made the limiting board that with frame be connected of bounding means for being provided with in the guide channel plate bi-side of plane motion.
The utility model has following beneficial effect:
1. in quadratic crank mechanism, replace hinge pin (revolute pair) connection that crank is connected with connecting rod, can improve mechanical efficiency about 20% with the transmission of racetrack gear mechanism.
2. in racetrack gear mechanism movement process, the point on the racetrack gear mass makes to move the compound motion that adds rotation, changes the arc section diameter and the length of straigh line of racetrack gear, can obtain different movement locus, can satisfy the different needs of mechanism design.
Now in conjunction with the accompanying drawings, with preferred embodiment
Fig. 1 is the utility model embodiment's a organigram.
Fig. 2 is that the 2-2 of Fig. 1 analyses and observe.
Fig. 3 to Fig. 5 is several forms of racetrack gear.
Fig. 4 is the schematic diagram of movements of the utility model when being applied to slidercrank mechanism.
Racetrack gear mechanism of the present utility model is made of cylindrical gears 1 and racetrack gear 2, cylindrical gears 1 is a fixed axis gear, be fixed in gear shaft 3, wheel shaft 3 is installed in the bearing support of frame 4, the end in addition of wheel shaft 3 is equipped with other driving components, and accompanying drawing not in qualification, is only represented its position with strong 5 to this driving component, gear shaft 3 does not have shaft part 6, is used for the guiding with the guide groove that is connected racetrack gear 27 that hereinafter will narrate.
Racetrack gear 2 is gears of likeness in form sports filed track, its gear teeth reticule is tangent and constitute the continuous noncircular gear of the peripheral gear teeth by two arc sections and two straightways, Fig. 2 to Fig. 5 shows several embodiments, two arc diameters that constitute its reticule among Fig. 3 are identical, two straightways are parallel, two arc diameters that constitute its reticule among Fig. 4 do not wait, small one and large one, two straightways tangent with it are not parallel.The racetrack gear of Fig. 5 is an internal gear.
For the engagement that makes cylinder wheel 1 and racetrack gear 2 keep the motion overall process, keep cooperating the location being connected with the guiding shaft part 6 that annular guide channel 7 and wheel shaft 3 are arranged on guide channel plate 8, this guide channel plate 8 on the racetrack gear mass, it is equidistant that the reticule of the center line of guide groove 7 and racetrack gear 2 keeps in whole ring surface, its distance equals the reference radius of cylindrical gears 1, and the guide groove width becomes to be slidingly matched with the diameter of wheel shaft guide section 6.
In order to realize that guide channel plate 8 does plane motion, need carry out axial limiting to guide channel plate, in the embodiment of Fig. 2 Fig. 3, this bounding means be that the limiting board 9 and 10 that links to each other with frame is set in guide channel plate 8 bi-side, also can be a side setting.
Fig. 4 is the embodiment that the utility model is applied to the motion of crank slot slide-block mechanism, represent cylindrical gears and racetrack gear with the gear compound graduation line among the figure, crank in the suitable linkage mechanism of half warp of figure middle gear 1, the connecting rod 11 hinged with slide block 12 is fixedly connected on racetrack gear 2, the Placement of crank and connecting rod is the engagement of racetrack external gear mechanism, its working principle is as follows: suppose that slide block 12 is moved to the left, at this moment the linear gear rack of racetrack gear top and fixed axis gear 1 engagement driving, be transferred to the tooth bar end, fixed axis gear 1 meshes with the semi-circle gear section of racetrack gear then, transmission commutates, commutation finishes, dead axle toe joint 1 meshes with the following tooth bar of racetrack gear, it is that slide block 12 moves to the right that the racetrack gear moves to right, go round and begin again like this, racetrack gear driven slide block 12 does reciprocating linear motion and fixed axis gear 1 is made circular movement.
