Abstract
The utility model discloses a tooth-shaped chain which comprises chain plates, outer chain plates, pin shafts, guide plates, connecting pin shafts and locking pieces. The chain plates and the pin shafts are connected in a clearance fit mode and are arrayed in a staggered mode. The outer chain plates are arranged on two sides of the chain and are connected with the pin shafts in a clearance fit mode. The chain plates are arranged in the middle of the chain and are connected with the pin shafts in a clearance fit mode. Two ends of each pin shaft are provided with square riveting heads. Slotting ends of the chain plates are provided with the locking pieces. Inner side tooth outlines of the chain plates are in an arc shape. Outer side tooth outlines of the chain plates are in a linear shape. The outer side tooth outlines of the chain plates of the chain are straight edges, the inner side tooth outlines are in the protruding arc shape, and the inner side tooth outlines and the outside tooth outlines are contacted with chain wheel teeth successively, so that inside and outside composite meshing is realized, impact and vibration are reduced, and noise is reduced. The outer chain plates in clearance fit with the pin shafts are adopted on the two sides of the chain, and the two ends of each pin shaft are of square riveting head structures, so that chain connection firmness is improved, and the chain is enabled to be applied to a multi-impact working condition.
Description
Technical field
The utility model relates to a kind of profile of tooth chain, particularly drives with low noise profile of tooth chain.
Background technique
Traditional standard tooth form chain is outer gearing, and carrier bar contacts with sprocket tooth with outside flank profil, and the engagement location is to finish instantaneous, and shock and vibration are bigger, and noise is bigger; Chain mainly is made of carrier bar, guide plate and bearing pin simultaneously, carrier bar and guide plate all with the bearing pin loose fit, arrive the soundness that bearing pin end die or increase connect with the packing ring assurance of bearing pin interference fit, because packing ring is thinner, it is not enough to cause connecting fastness, easily because lateral force causes carrier bar and bearing pin to throw off, chain can not transferring power in the work.
The model utility content
The purpose of this utility model be for solve above-mentioned the deficiencies in the prior art provide a kind of simple in structure, shock and vibration are little, noise is low, connect solid and reliable profile of tooth chain.
The utility model adopts following technological scheme:
A kind of profile of tooth chain comprises carrier bar, outer plate, bearing pin, guide plate, connection bearing pin and fastener, and carrier bar connects with the bearing pin Spielpassung and is staggered; Outer plate connects with the bearing pin interference fit in the chain both sides; Carrier bar connects with the bearing pin Spielpassung in the middle of chain; Four directions, bearing pin two ends die, the fluting end of carrier bar is provided with fastener, and the inboard flank profil of described carrier bar is convex, and the outside flank profil of carrier bar is shape linearly.
The carrier bar outside flank profil of chain of the present utility model is a straight flange, and inboard flank profil is convex, realizes inboard flank profil and the inside and outside compound engagement that outside flank profil successively contacts with sprocket tooth, has reduced to impact and vibration, has reduced noise; At the outer plate of chain both sides employing with the bearing pin interference fit, cubic die structure is adopted at the bearing pin two ends, and increase chain and connect fastness, be the operating modes that chain more is applicable to many impacts.

Embodiment
As Fig. 1,2,4, a kind of profile of tooth chain comprises carrier bar 1, outer plate 2, bearing pin 3, guide plate 4, connects bearing pin 5 and fastener 6, and carrier bar 1 connects with bearing pin 3 Spielpassung and is staggered; Outer plate 2 connects with bearing pin 3 interference fit in the chain both sides; Carrier bar 1 connects with bearing pin 3 Spielpassung in the middle of chain; Four directions, bearing pin 3 two ends die, the fluting end of carrier bar 1 is provided with fastener 6, and the inboard flank profil 11 of described carrier bar 1 is convex, and the outside flank profil 12 of carrier bar 1 is shape linearly.
As Fig. 3, the inboard flank profil 101 of the carrier bar 100 of original common chain and outside flank profil 102 all are skew lines, as Fig. 4, the inboard flank profil 11 of carrier bar 1 of the present utility model is convex, outside flank profil 12 is shape linearly, like this when a lot of carrier bars link together, as Fig. 5, the inboard flank profil 11 of chain assembling back carrier bar A can be higher than the outside flank profil 12 of carrier bar B, like this in the time of chain and sprocket engagement owing to be convex, as Fig. 6, with drive sprocket when engaging-in, engagement in the inboard flank profil of evagination at first realizes with the gear teeth 13 is shown in the carrier bar A of Fig. 6 in the silent chain transmission process; Along with going deep into of engagement, relatively rotate between adjacent link, the gear teeth are realized outer gearing with the carrier bar of adjacent link outside flank profil gradually, as the carrier bar B of Fig. 6, finish an engaging-in process; Realize inboard flank profil and the inside and outside compound engagement that outside flank profil successively contacts with sprocket tooth, reduced to impact and vibration, reduced noise.
