PROBLEM : Weight reduction trick
REASONS : Weight reduction trick
TORKPT DIFFERENCE: Manufactured within standards without considering the cost impact, product number SPB-300-2 weighs 8.70 Kg in the Torkpt brand, while it weighs 7.15 Kg in the other brand.
PROBLEM : Manufacturing outside the standard model
REASONS : Non-standard manufacturing
TORKPT DIFFERENCE: Manufactured within standards without considering the cost impact. While product number SPB-200-2 is a standard model in the Torkpt brand, it is non-standard in the other brand.
PROBLEM: Casting defects
REASONS : Improper, uncontrolled conditions in the casting process
RESULTS : Visible or invisible casting cavities can affect the strength of the pulley and also cause balancing. If there is a gap in the groove, it will cause the belt to deform and tear.
TORKPT DIFFERENCE: Casting gaps that may occur inside the bushings and bolts will cause stripping and prevent the desired performance. Controlling the conditions in the casting process
PROBLEM: Undersized couplings
REASONS : Cost reduction trick
RESULTS : When choosing a coupling, the moment value that can be met with a product of smaller diameter and length should be met by a product of larger diameter.
TORKPT DIFFERENCE: Manufacturing within standards without considering cost increases
PROBLEM: Improper casting spectral analysis
TORKPT DIFFERENCE: Full-fledged casting laboratory, expert technical team, traceable process control and archiving
REASONS : Cost reduction trick
RESULTS : Decrease in product strength, cracking, breakage, ruptures
TORKPT DIFFERENCE: Manufacturing within standards without considering the cost impact
PROBLEM: Incorrect groove angle
TORKPT DIFFERENCE: Continuous checks with special angle gauges
PROBLEM: Bad taper bush angle
TORKPT DIFFERENCE: Appropriate equipment is provided and checks are made constantly with bushing gauges.
PROBLEM: Incorrect groove depth
REASONS : Cost reduction trick
RESULTS : Fraudulent model selection and incorrect processing to reduce costs. If the groove depth is entered less than it should be, the belt will fit perfectly into the channel and there will be no space under the belt. This causes the belt not to breathe, premature heating of the belt, deformation of the belt due to heating, and premature breakage. Depth values for channel profiles are determined according to standard DIN 2211.
TORKPT DIFFERENCE: Continuous checks with special angle gauges, selection of models in accordance with the standard
PROBLEM: Secretion
PROBLEM: Balance
RESULTS : If the balance is not taken, which is a mass imbalance caused by the difference between the geometric center and the center of rotation, an extra dynamic load will occur on the pulley, which will cause unwanted vibrations. In addition, the life of the bearing will decrease significantly due to unbalanced loads falling on the bearing .
TORKPT DIFFERENCE: Balancing up to g0.4 precision with the world's best SCHENK brand balancing machine, reporting and archiving
PROBLEM: Extreme surface roughness
RESULTS : If the roughness in the grooves is high, the belts will wear out quickly and break. If it is smoother, the desired winding may not occur as the friction coefficient between the belt and pulley will decrease.
TORKPT DIFFERENCE: Use of quality diamonds, continuous control and archiving of casting spectral analyses, production with the most accurate cycle and progress, measuring, reporting and archiving with the surface roughness device at the final control.
TORQUE DIFFERENCE: Use of phosphate materials that can obtain products resistant to 76-hour salt fog test by continuously performing chemical analyzes of the phosphating process.
PROBLEM: Corrosion and rust
REASONS: Incorrect and poor quality coating material selected, incorrect coating processes, water, corrosive fluid, intense humidity and incorrect packaging conditions.
TORQUE DIFFERENCE: Use of phosphate materials that can obtain products resistant to 76-hour salt fog test by continuously performing chemical analyzes of the phosphating process.
