Abstract
The utility model relates to a driving device, particularly a driving chain for a stepless speed variator. The utility model is composed of a driving chain plate, a saddle-shaped chain plate, a gasket and balance pins. The driving chain plate is arranged side by side on two symmetric pin shafts. The saddle-shaped chain plate carries out the function of axial location to the driving chain plate by clamping the gasket which has a small clearance fit with the pins. The utility model has the advantages of high driving efficiency, stable operation and long service life.
Description
The utility model relates to a kind of transmission device, especially for the Transmitted chains of stepless speed variator.
Stepless speed variator is the continuously adjustable mechanical transmission of a kind of velocity ratio (being gear ratio), and this transmission device not only stable drive, speed change is nimble, and helps making work mechanism to move by the optimized design parameter.Known stepless speed variator has the numerous species type, and wherein the stepless speed variator with the endless flexible element transmission has: (one) belt (as wide V belt) formula stepless speed variator.Its driving wheel 1, follower 2 are formed by two separable cone pulleys, and with V-Belt Drive, the velocity ratio of this stepless speed variator is r
2/ r
1, promptly work as driving wheel and separate, when follower is drawn close, be gearing down; Otherwise driving wheel is drawn close, and follower then is the speedup transmission separately.The stepless speed variator of this pattern is not only simple in structure, and requirement on machining accuracy is lower, and the transmission balance; But its size is big, slip is higher, belt life is short, the interior frictional loss of speed changer is bigger.(2) gear chain type stepless variable speed unit, this stepless speed variator are to realize transmission by the toothed chain slide plate with engagement between the cone pulley teeth groove.Since between its toothed chain and cone pulley arbitrarily the diameter of size be meshed, so the dependence cone pulley separates or draws close just continuously variable.Compare with friction type stepless speed changer, it is accurate that gear chain type stepless variable speed unit has speed governing, seldom skid, and stabilization of speed, efficient is than advantages such as height; But because it is chain-driven basically, not only chain line speed is restricted, and can't realize the high speed transmission, and it is instantaneous than non-constant to have chain-driven, and the awl dish is made complicated, the shortcoming that the slide plate abrasion is bigger.
The purpose of this utility model is to provide a kind of transmission efficiency height, and the Transmitted chains of stable drive and long service life is promptly put pin formula Transmitted chains, is specially adapted to stepless speed variator.
The Transmitted chains that the utility model provides is by drive link 2, saddle type carrier bar 4, and packing ring 1 and pendulum pin 5 four parts are formed, and it is characterized in that:
(1) curved profile is made at the two ends of pendulum pin 5, and side profile is made up of three parts:
-working curved surface can be multinomial class, trigonometric function class, hyperbola class function or its combination;
-plane of orientation;
-make working curved surface and plane of orientation that the garden cambered surface of good transition be arranged.
(2) endoporus of two symmetries is arranged on the drive link 2, profile also is made up of three parts:
-plane of orientation is in the outside of Transmitted chains, has one less than 10 ° inclination angle with respect to the heavy face of lead;
-great circle cambered surface is in the inboard of Transmitted chains;
-little arc surface, making between locating face and the great circle cambered surface has transition well.
(3) saddle type carrier bar 4 bore dias are slightly less than drive link 2 bore dias.
(4) on the bearing pin 5 of two symmetries, drive link 2 is settled side by side, and saddle type carrier bar 4 has the packing ring 1 of a less Spielpassung by clamping and bearing pin 5, comes drive link 2 is played axially locating.
The pendulum pin chain that the utility model is designed makes chain to do and relatively rotate along with adjacent link, compensates polygon effect according to certain rules, has reduced the vibration or the noise that produce owing to polygon effect to greatest extent.In addition, the rolling between the pendulum pin has replaced the slip of drive link and bearing pin, has reduced the wearing and tearing between the rotating component, thereby this Transmitted chains transmission efficiency height, energy-conservation.Moreover the design has only four kinds of parts, and is simple in structure, thereby inertial force is little when the high speed underdrive, can realize high-power transmission.Be described in detail the utility model below in conjunction with accompanying drawing by embodiment.
Accompanying drawing 2 is the horizontal cut-away view of pendulum pin chain.
Embodiment
As shown in Figure 1, 2, for a kind of pendulum pin chain that is used for stepless speed variator, on the pendulum pin 5 of two symmetries, drive link 2 is staggered placed side by side, saddle type carrier bar 4 has the packing ring 1 of a less Spielpassung by clamping and bearing pin 5, comes drive link 2 is played axially locating.Curved profile is made at the two ends of pendulum pin 5, and the awl of stepless speed variator coils 3 clampings the two ends of pendulum pin with transferring power.
The utility model can be used for the transmission of various devices, is specially adapted to stepless speed variator.
