Invention content
The technical problem to be solved by the utility model is to provide a kind of thinned connection group toothed belt is provided, solve existing
The resistance to performance that circumnutates of grouped belt dynamic operation makes Crack Fatigue life time improve 3-5 times, and improves articulamentum intensity, flatness
The long service life for extending grouped belt.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of group of toothed belt is arranged in order abrasion resistant fibrous top glue, high-strength nylon cloth articulamentum, high mode and low mode from top to bottom
Polyester cord, heat resistant and wear resistant fiber primer, grid Anti-cracking cloth, the abrasion resistant fibrous top glue and heat resistant and wear resistant fiber primer
It is kneaded, and is added wherein evenly dispersed by high-strength technoeaT200 aramid fibers staple fiber using ethylene propylene diene rubber
Manufactured complex, it is and abrasion resistant fibrous after the high-strength nylon cloth articulamentum is using the leaching ethylene propylene diene rubber processing of nylon66 fiber cloth
Glue and the molding bonding of high mode and low mode polyester cord are pushed up, and among abrasion resistant fibrous top glue and high mode and low mode polyester cord.
Further, high mode and low mode polyester cord can also be aramid line strength layer.
Further, high-strength nylon cloth connects layer thickness in 2.5-2.8mm.
Further, the size model number of high-strength nylon cloth is：95/100mm of broadwise, 80/100mm of warp-wise.
Further, tooth Shape Design specification is pitch 12.5mm, tooth depth 6.5mm, R circular arc, 12 ± 0.3mm of tape thickness.
It is using advantageous effect caused by above-mentioned technical proposal：
Abrasion resistant fibrous top glue and heat resistant and wear resistant fiber primer are kneaded using ethylene propylene diene rubber, and are added simultaneously high-strength
Aramid fiber makes belt higher intensity be driven, and has higher lateral stiffness and wear-resisting property, outstanding heat-resisting quantity, resistance to song
Around performance；Integrated vulcanizingization designs, high-strength nylon66 fiber cloth is added and does articulamentum, the good bonding of unique impregnation technical guarantee
Performance prevents in use the articulamentum band that falls off and cut to tear band problem, and (12.5 tooth depth 6.5R circular arcs of pitch are set for the flute profile design of optimization
Meter) coordinate thickness that (12 ± 0.3) are thinned, the SB jointed toothed bands for being have outstanding dynamic fatigue crack performance.Skeleton material
Material uses high-strength aramid cord or high mode and low mode polyester cord, ensure that with the enough intensity of body；100 hours fatigue in use
Strengthen and only has 0.80% to substantially exceed national standard using elongation；Greatly extend service life.
