Abstract
The utility model discloses a pitch-changing tooth-shaped chain of an external gearing mechanism. The pitch-changing tooth-shaped chain comprises a guide sheet and a working chain plate which are connected with each other through hinge pins. A couple of chain plate holes are symmetrically arranged on the working chain plate. The chain plate holes are vertically symmetric. Two sections of circular arcs with different diameters are respectively arranged on the left side and the right side of the chain plate holes, and opposite circular arc endpoints are connected through indented curves. The circular arc with a big radian is close to the center line of the working chain plate, and the chain plate holes are in fit with the hinge pins. According to the tooth-shaped chain, the pitch-changing function in a transmission process is achieved, polygon effects of chains of the tooth-shaped chain are reduced, shock and vibration are reduced, noise is lowered, and abrasion is mitigated.
Description
Technical field
The utility model belongs to silent chain transmission system, be specifically related to a kind of pitches silent chain with outer gearing mechanism, be specially adapted to the fields such as motor car engine, automobile gearbox and transfer case, steam turbine, industrial pump, metallurgical machinery, chemical machinery, oil-well rig.
Background technique
Because the noise that has of silent chain itself is low, reliability and the higher Some features of kinematic accuracy, in recent years, the motors such as automobile, motorcycle and fork truck have been used silent chain more and more widely.Usually the difference of silent chain push-piece shape shaft is divided into two large classes: round pin formula silent chain and pitches silent chain.Product and the specification of silent chain are various, and application is very extensive, and " personalization " is very obvious.The chain plate hole of existing silent chain carrier bar is to be approximately circular, the bearing pin that cooperates with it is the round pin axle of ordinary construction, the fit form of carrier bar and bearing pin is more single, and the silent chain pitch can't be regulated, and can't satisfy " personalization " actual demand of different main frames, different operating modes.Existing U. S. Patent U.S.Pat.No.4,904,231 and U.S.Pat.No.4,186,617 chain plate hole and bearing pin shape are improved, but the silent chain that patent Pat.4904231 relates to be fine pith interior-outer compound tooth-shaped chain, the silent chain that patent Pat.4186617 relates to is roller chain.
Summary of the invention
The problems referred to above that exist in order to overcome the prior art field, the purpose of this utility model is, a kind of pitches silent chain of outer gearing mechanism is provided, it is single to solve existing silent chain structure, can't satisfy the problem of different main frames, different operating mode demands.
The pitches silent chain of the outer gearing mechanism that the utility model provides, it comprises guide card, work carrier bar, the work carrier bar is connected by bearing pin with guide card, described work carrier bar is provided with a pair of symmetrically arranged chain plate hole, the up and down symmetry of described chain plate hole, the left and right sides of chain plate hole is two sections circular arcs that diameter does not wait, and relative circular arc end points is by the curve connection of indent, the close work of the circular arc carrier bar center line that radian is large, the chain plate hole cooperates with bearing pin.The described bearing pin that cooperates with the chain plate hole comprises the axle of having strong market potential, short pin shaft, and the described axle of having strong market potential, short pin shaft are arranged in the chain plate hole rolling.The inboard flank profil of described work carrier bar is curve or the rectilinear form of indent, and the outside flank profil of work carrier bar is shape linearly, the outside straight-side profile of described work carrier bar and sprocket teeth engagement.
The pitches silent chain of the outer gearing mechanism that the utility model provides, its beneficial effect are, have realized the pitches function in the silent chain transmission process; Reduce the polygon effect of silent chain chain, reduced shock and vibration, reduced noise, alleviated wearing and tearing.
Description of drawings
Fig. 1 is the utility model embodiment's overall structure schematic representation;
Fig. 2 is the overall structure schematic representation of carrier bar 3 of working among Fig. 1.
Mark among the figure:
1. outside flank profil; 2. chain plate hole; 3. work carrier bar; 4. inboard flank profil; 5. the axle of having strong market potential; 6. short pin shaft.
Embodiment
With reference to the accompanying drawings, in conjunction with the embodiments, the pitches silent chain of the outer gearing mechanism that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the pitches silent chain of the outer gearing mechanism of present embodiment, it comprises guide card, work carrier bar 3, work carrier bar 3 is connected by bearing pin with guide card, and described work carrier bar 3 is provided with a pair of symmetrically arranged chain plate hole 2, the up and down symmetry of described chain plate hole 2, the left and right sides of chain plate hole 2 is two sections circular arcs that diameter does not wait, and relative circular arc end points connects by the curve of indent, the close work of circular arc carrier bar 3 center lines that radian is large, and chain plate hole 2 cooperates with bearing pin.The described bearing pin that cooperates with chain plate hole 2 comprises the axle 5 of having strong market potential, short pin shaft 6, and the described axle 5 of having strong market potential, 6 pairs of short pin shafts roll and be arranged in the chain plate hole 2.The inboard flank profil 4 of described work carrier bar 3 is curve or the rectilinear form of indent, and the outside flank profil 1 of work carrier bar 3 is shape linearly, the outside straight-side profile 1 of described work carrier bar 3 and sprocket teeth engagement.
The inboard flank profil 4 of work carrier bar 3 is that curve or the straight line by indent consisted of, thereby the profile of tooth chain forms outer gearing mechanism silent chain in the course of the work by the outside flank profil 1 and sprocket teeth engagement of carrier bar, and engagement is located more stable.By a pair of bearing pin to rolling, have strong market potential axle 5 and short pin shaft 6 connect, and can realize the pitches function in the silent chain transmission process, thereby reduce the polygon effect of chain, reduce shock and vibration and noise, alleviate wearing and tearing between the chain plate hole 2.
