The purpose of this utility model can also be achieved through the following technical solutions:
Further:Three eccentric gears are installed, the both sides of each eccentric gear are fitted with two in the casing Non-circular gear, each eccentric gear simultaneously with two non-circular gear gear motions.
Further:The non-circular gear is fixedly installed togather with crank, and peace is fixed in one end of non-circular gear and crank On crank bearing, non-circular gear drives crank to be rotated around crank bearing, crank handle turns reciprocating motion of the pistons.
Further:Three cranks of non-circular gear homonymy are in space arrangement in three groups of Double-action reciprocating motions It is upper to be fixed in 120 degree of uniform distributing installations.
The beneficial effects of the utility model are:A kind of speed change Double-action reciprocating motion of the utility model is by using one The engaged transmission of individual eccentric gear and two (or one) non-circular gears, realizes the target of the Double-action reciprocating motion of mechanism, And can voluntarily change in reciprocatory movement output torque size and move back and forth speed size, with compact conformation, The characteristics of efficiency high, low energy consumption, moreover, the crank of eccentric gear both sides is spatially in 120 degree of (or uniform) distributions, increase Mechanism traveling comfort.
Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description In become obvious, or by it is of the present utility model practice recognize.
Brief description of the drawings
Of the present utility model above-mentioned and/or additional aspect and advantage will from description of the accompanying drawings below to embodiment is combined Become substantially and be readily appreciated that, wherein:
Fig. 1 is according to a kind of structural representation of speed change Double-action reciprocating motion of the present utility model;
Fig. 2 is the structural representation according to piston mechanism of the present utility model;
Fig. 3 is the structural representation according to single group reciprocating mechanism of the present utility model.
Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.
In the utility model, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " Gu It is fixed " etc. term should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected;Can It to be to be joined directly together, can also be indirectly connected to by intermediary, can be the connection of two element internals.
A kind of mechanical motion mechanism technical field according to the utility model embodiment is described below with reference to Fig. 1-Fig. 3, especially It is to be related to a kind of speed change Double-action reciprocating motion.
According to a kind of speed change Double-action reciprocating motion of the utility model embodiment, including:It is casing 1, bearing 2, defeated Enter axle 3, input shaft support base 4, eccentric gear 5, non-circular gear 6, crank 7, crank bearing 8 and piston mechanism 9.
As shown in figure 1, it is respectively lower box 1 (1) and upper box 1 (2), the upper box 1 that casing 1 is made up of two parts (2) and lower box 1 (1) edge is machined with through hole, they are connected by bolt.The left and right sides of casing 1 is provided with bearing 2, multiple keyways are machined with input shaft 3, the input shaft 3 to support and fix, input shaft 3 is rotated and provided for reciprocator Power;The bottom of input shaft support base 4 is fixed on lower box 1 (1) and provides intermediate supports with input shaft 3 is combined into bearing 2;Institute State and 3 size identical eccentric gears 5 are separately installed with input shaft 3 are rotated with the axis as driving wheel;The non-circular gear 6 into It is fixed on to being distributed in the left and right sides of eccentric gear 5, and by key on the bent axle of the one end of crank 7, its gear teeth and eccentric tooth Wheel 5 is engaged, and is rotated as driven pulley with eccentric gear 5;The crank 7 is fixed on crank bearing 8 by both sides crank axle On, the center crank axle of crank 7 is connected with piston mechanism 9, and two non-circular gears 6 of the left and right sides are under the driving of eccentric gear 5 Rotating Vortex so drive both sides crank 7 rotate, most rotary motion is converted into the linear reciprocation of both sides by piston mechanism 9 at last Motion.
9 points of piston mechanism as shown in Figure 2 is that connecting rod 9 (1), piston ram 9 (2), piston cylinder 9 (3) and pivot pin 9 (4) are constituted, Connecting rod 9 (1) one end is connected with the center crank axle of crank 7, and the other end is connected by pivot pin 9 (4) with piston ram 9 (2), driving Piston ram 9 (2) is moved back and forth in piston cylinder 9 (3).
As shown in figure 3, in reciprocatory movement, eccentric gear 5 is rotated with input shaft 3, the conduct of eccentric gear 5 Active wheel drive both sides non-circular gear 6-1 and 6-2 rotating Vortex, drives both sides piston mechanism 9 to do reciprocal fortune in the same direction by crank 7 It is dynamic, so as to ensure that opposite side piston mechanism 9-2 reversely does work when piston mechanism 9-1 forward directions in side are done work;Work as piston mechanism During 9-2 forward direction actings, the near-end of eccentric gear 5 is engaged with non-circular gear 6-2 long end, in the situation that the moment of torsion of input shaft 3 is constant Under, eccentric gear 5 passes to non-circular gear 6-2 power increase, and then increases non-circular gear 6-2 output torque driving piston machine Structure 9-2 externally does work;At the same time, when piston mechanism 9-1 reversely does work, the long end of eccentric gear 5 is nibbled with non-circular gear 6-1 short ends Close, add the length of the arm of force, improve non-circular gear 6-1 rotary speed to shorten the time do not done work.
In short, according to a kind of speed change Double-action reciprocating motion of the utility model embodiment, by using one The engaged transmission of eccentric gear and two non-circular gears, realizes the target of the Double-action reciprocating motion of mechanism, and reciprocal By changing the length of the arm of force in motion process, it can voluntarily change both sides non-circular gear output torque size and piston mechanism is reciprocal The size of movement velocity is low with compact conformation, size, efficiency high, the energy consumption that can voluntarily change output torque and reciprocating speed The characteristics of, moreover, the crank of eccentric gear both sides adds mechanism traveling comfort spatially in 120 degree of distributions.
