Abstract
The utility model relates to a variable pitch roll pin type tooth-shaped chain for a gasoline engine transfer case, which can effectively eliminate polygonal effect and has low noises and long service life. The variable pitch roll pin type tooth-shaped chain comprises a tooth-shaped chain; an abnormal pin shaft hole in a chain plate of the tooth-shaped chain is a plagiohedral side lay arc-shaped hole; the plagiohedral side lay arc-shaped hole is internally provided with an abnormal long pin shaft and an abnormal short pin shaft; and relative shaft faces of the abnormal long pin shaft and the abnormal short pin shaft are in rolling match. The variable pitch roll pin type tooth-shaped chain for the gasoline engine transfer case has the advantages that firstly, the variable pitch roll pin type tooth-shaped chain is hinged with a non-circular pin shaft; the polygonal effect can be compensated in a high-speed movement process; the variable pitch roll pin type tooth-shaped chain is particularly suitable for speed changing working conditions of the high-speed, variable-load and multi-impact transfer case, so that the polygonal effect is reduced, impact and vibration are reduced, the noises are reduced and the transmission efficiency is improved; and secondly, the structure is compact, the transmission power is high, and the reliability and the wear resistance are high.
Description
Technical field
The utility model relates to a kind ofly can effectively eliminate polygon effect, and noise is low, and the life-span, the long pitches that is used for the petrol engine transfer case rolled pin formula silent chain, belonged to auto parts and components and made the field.
Background technique
CN101451451A, title " timing chain of motor ", comprise the carrier bar that is connected into chain and the bearing pin that is connected each carrier bar, every section chain is combined by chain sheet arranged side by side, the mutual embedding that interlocks of the chain sheet of the adjacent chain of each section, connect with bearing pin, the inboard of chain sheet is shaped with the involute sprocket, chain is embedded in rubber tape, make an integral body with rubber tape, the flank of tooth of sprocket is equal with the inboard toothed surface of rubber tape, the outer fix of chain is embedded with tyre cord in rubber tape, and the rubber tape material adopts nitrile rubber or fluorine rubber.Its deficiency: the Timing Gear Chain hinge is circular bearing pin, with the involute engagement process in have polygon effect impact, chain is produced greater impact, serious wear, noise is large, working life is short.
The model utility content
Purpose of design: avoid the deficiency in background technique, design and a kind ofly can effectively eliminate polygon effect, noise is low, and the life-span, the long pitches that is used for the petrol engine transfer case rolled pin formula silent chain.
Design proposal: in order to realize above-mentioned purpose of design.On the basis of the timing chain of available engine, make further improvements by the structural type to chain, thereby realized long lifetime and the low noise of motor car engine transfer case speed variator system chain.On structural design, pitches rolls pin formula silent chain hinge structure and is comprised of 2 bearing pins and rolls pin combination, as shown in Figure 1, opposite sex bearing pin width is about 4/5 of chain panel aperture, 1/2 of length, have strong market potential axle and guide plate interference fit, short pin shaft coordinates with carrier bar, form rolling condition between the two, reduce the wearing and tearing of special-shaped pin and chain plate hole.
Technological scheme: a kind of pitches for the petrol engine transfer case rolls pin formula silent chain, comprise silent chain, special-shaped pin axis hole in carrier bar in described silent chain is partial shape rule side arcuate socket, and partial shape rule side arcuate socket is built-in with abnormity axle and special-shaped short pin shaft and the abnormity axle axial plane relative to special-shaped short pin shaft of having strong market potential of having strong market potential and is to roll and coordinates.
The utility model is compared with background technique, the one, because pitches rolls pin formula silent chain hinge because of the non-round pin axle of its hinge, can compensate polygon effect during high-speed motion, particularly suitable high speed and variable load, the transfer case speed change working condition that impacts more, reduced polygon effect, reduce shock and vibration, reduce noise, improve transmission efficiency; The 2nd, compact structure, transmitted power are high, reliability and wear resistance high.
