The shock absorbing caster can adjust the uneven ground because of its special structure. Rubber absorbing castors have rubber as buffer material; spring absorbing casters have spring as buffer material; there are some casters with rubber and spring as buffer materials.
Shock absorption caster plays an important role in industry. It is a measure to mitigate the impact of mechanical vibration. There are various kinds of impact problems in engineering, such as aircraft landing, rapid reciprocating movement of machine tool components, lifting or dropping of packaging materials, etc., which will impact the machinery and foundation.Under the action of impact force, mechanical parts will produce great dynamic stress, which may lead to damage, and the surrounding machinery and buildings may also be damaged. Therefore, buffer or isolation measures should be taken for all unnecessary impact force in mechanical engineering.For example, the buffer must not be placed in the bottom of the forging block. Buffering is different from vibration isolation and vibration reduction. It uses the buffer device to absorb the energy of impact, and then converts it into heat energy, or releases it gently to prolong the time of speed change, so as to achieve the purpose of minimizing the impact force on mechanical equipment.
In the process of operation, the absorbing caster stores the kinetic energy of the object vibration into its own elastic potential energy by the elastic body. The fluctuation of the elastic potential energy ensures the safety of the loaded object.
For example, Shangxin high elastic CP45 Series casters are different from ordinary casters in their shock absorption devices
1、 Easy to start.
Shangxin high elastic CP45 series caster adopts high-quality iron core and polyurethane wheel. Polyurethane has good flexibility, elasticity and wear resistance. When it is installed on the equipment vehicle, it can not only reduce the noise but also reduce the starting power.
2、 High load steering resistance.
Heat treatment process is adopted for caster steering ball disc, which can greatly improve the hardness and toughness of the bottom plate and large bullet cover of bearing steel ball. It can turn better in the process of high load traction, greatly reduce unnecessary wear and noise, and reduce costs for the workshop. And provide a quiet production environment.
3、 Shock absorption performance.
The spring load caster adopts high-quality shock resistant spring, which makes the wheel rotate more flexible and easy, greatly improves the stress performance, protects the wheel and bracket, and avoids the damage of caster and machinery or goods caused by vibration when the wheel is walking on concave and convex ground.
