Please check pu castor bolt tightness, castor production after 24 hours, after the completion of rolling experiments according to the product requirements, set different products of different rotating speed, load, and the obstacles, products in the reach regulation as a qualified after stroke. Impact test: will castor vertical backward in impact testing machine test platform, using the rules from the corresponding height to the bottom of the free falling impact castor wheel surface, castor without damage as qualified. Static load test: the casters on the static load tooling, fixtures pressure above the corresponding weight, static measuring wheel deformation after 24 hours, after test to detect casters deformation does not exceed 3% of the wheel diameter, and the test after the completion of the caster can use normally regarded as qualified. If there is no damage to the parts can be reassembled continue to use, if often meet the wheels is sundry winding phenomenon Suggestions can avoid assembly anti-wind cover. Universal wheel is loose or wheels stuck also can cause & other; Grinding flat spot & throughout; 。 Proper maintenance check, especially check bolt tightness, lubricating oil, to replace the damaged rolling performance and rotary motion of the wheel can enhance flexibility. Through the buffer shock absorption structure damping principle castor road uneven on the impact of the carrier, guarantee the smooth, in the process of vehicle handling of parts in the process of slow transportation vibration and damage, shock absorbing materials are generally rubber shock absorption and spring damping, rubber and rubber rubber and polyurethane rubber piece, spring suspension style is more, a single coil and looks, springs and spring tree and transverse spring damping, used on rough ground, should wear resistance and resilient rubber, polyurethane or super synthetic rubber wheels; Through the buffer shock absorption structure road uneven on the impact of the carrier, guarantee the smooth, in the process of vehicle handling of parts in the process of slow transportation vibration and damage, shock absorbing material generally is rubber shock absorption and spring damping two kinds, glue and rubber rubber and polyurethane rubber piece, spring suspension style is more, a single coil and looks, springs and tree spring and spring suspension, universal wheel loose castor wheels or jammed also can cause & other; Grinding flat spot & throughout; , the appropriate maintenance check, especially check bolt tightness, lubricating oil, to replace the damaged rolling performance and rotary motion of the universal caster wheel can enhance flexibility.
