Fault 5: Inching synchronous tooth belt broken reasons: 1 year long fatigue cut off; 2 improper use of maintenance, oil aging rubber aging, or accidental force breaking.
Repair: 1 for imported parts, part number 00.780.2156 toothed belt; 2 according to West Germany DIN standard -33T101250 drawing processing (or mapping physical objects). Material selection of polyurethane or neoprene can be, the inner core must use steel wire, otherwise the strength is not enough Polyurethane tape has many advantages such as oil resistance, wear resistance, cold and heat resistance, etc. It is easy to process and only needs to do the mold. Therefore, hope that all manufacturers do not blindly duplicate the mold, resulting in waste, should cooperate with each other, mold share; 3 redesigned processing belt Rotating domestic belts;
A. The improved design is to synchronize the arc-shaped toothed belt transmission structure (that is, HTD belt transmission, wheel, belt full change);
B. Improve the design of the national standard ladder tooth synchronous belt drive structure;
C. Improve the design for the national standard multi-wedge belt drive structure;
D. Improve the design of the national standard V-belt or universal belt drive structure.
The main design parameters are: transmission ratio i=8.4; speed n1=450 r/min; power 0.28KW; center distance of pulley 315mm
With a thickness of 5mm, width 33mm.
The above four improved designs have their own characteristics: A design is the best, because it is transformed from the fault of the trapezoidal tooth timing belt, the circular tooth profile is symmetrically distributed and uniformly transmitted to the core, so it is more synchronous than the trapezoidal tooth. The belt can transmit more torque, and is easy to process and low in cost. It has been developed by scientific research institutions. The C design is also relatively simple and inexpensive. It can transmit large torque, but the tensioning device must be considered because it is the same as D. Is driven by frictional tension; D design is the simplest, low cost, but the performance is poor, the transmission of torque is small (because of space constraints set tensioner), easy to slip wear heat, auxiliary repair time. Please all manufacturers to adjust measures to local conditions, choose the best overall efficiency program.
Fault 6: Unstable delivery drive Cause: 1The chain is too loose or too tight, 2 chain is seriously worn out, and the pitch becomes longer. If the accumulated error is too large, the chain wheel may be damaged.
Repair: 1 Check the adjustment of the center distance of the sprocket so that the elasticity is appropriate. (2) When the wear is serious, replace the new chain, the figure number is: 47.014.015;
Or according to the D/N standard external processing chain; or according to the national standard redesigned sprocket chain.
Effect: Compared with the purchase of the import chain, the cost can be reduced by 24 times, that is, for each change of a delivery chain.
Fault 7: Swing the paper row to swing, and the reason for the skew of the tooth row: The delivery shaft seat and the chain link wear badly, sometimes the diameter wear amount is more than 1mm, the part number is axis 00.550.0674
Shaft seats 93.014.305F, 93.014.306F.
Repair: 1 In the boring machine, the shaft seat is reamed with a boring sleeve, and 40Cr is used as a pin, and quenching and grinding; 2 Surveying and processing of cast steel shaft seats, drawings are omitted.
Fault 8: The reason why the paper is discharged is: (1) Loose fixing screws; (2) Caulking spring failure; (8) Criterion tooth wear, 4 tooth decay, part number 93.014.310.
Repair: 1 fastening screws, processing and replacement of wearing parts; 2 enamel teeth brush plated chrome layer, partial repair emergency; 3 partial adhesion wear layer emergency.
