The technical requirement is the summary of the caster or wheel before production and processing. It is an important indicator for improving the quality of the caster during normal production. When we produce the caster or wheel, we can effectively operate in accordance with the technical requirements. Improve product quality and reduce defective products; of course, different parts have different technical requirements, and reasonable technical requirements are also the most basic guarantee. Now caster manufacturers follow the GBT standard to implement, which also regulates casters or wheels The technical requirements of the company have also improved the universal usability.
Appearance technical requirements:
1. All parts should not have defects that affect the use, and the surface of metal parts should be effectively prevented from rusting.
2. The surface of the parts should be uniform in color;
Assembly technical requirements:
1. Rotating parts (wheels, brackets) should rotate flexibly, without jamming and loosening;
2. The wheel assembly should be firm, and the axle should not rotate with the wheel;
3. The braking device of the brake caster should have reliable performance;
4. The bracket steering clearance should be 0.1mm-0.2mm;
5. The main dimensions of casters and wheels should comply with GBT regulations;
Technical requirements for wheel runout: end face runout tolerance is 1.0% of wheel diameter D, radial runout tolerance is 0.5% of wheel diameter D;
Technical requirements for overload capacity:
The residual deformation of the wheel diameter D after the overload test should meet the requirements of the following table
Technical requirements for static pressure resistance:
After the static pressure resistance test, the caster should maintain the following properties:
a. The rotating parts can rotate flexibly, without jamming and loosening;
b. The wheel axle does not rotate, and there is no deformation that affects the rotation of the wheel;
Technical requirements for walking performance:
Under the test conditions, the casters or wheels should meet the following requirements after crossing 500 obstacles on the walking test machine:
a. Tire cracks and local excessive wear of the peeling machine;
b. There is no abnormal damage to the parts of the caster and permanent deformation that affects the use;
c. The bearing (shaft sleeve) rotates normally without seizure and looseness;
