The Differences Between Polyurethane Casters and Rubber Wheels?
Sep. 03, 2020
The popular PU Castor Wheels are casters used more and more in the industry. Polyurethane has attracted attention due to its excellent characteristics, pollution-free, and wide application temperature range. Polyurethane castor wheels are divided into castor wheels and polyurethane wheels. Casters, casters usually use barrel iron, and then coat the outer surface of the wheel hub with polyurethane to complete the treatment of the polyurethane casters, and place them neatly before covering the casters with polyurethane.
At present, this application is done manually, which requires a lot of time and labor. Regarding different problems in use, the mechanism for automatically holding the casters is as follows. The specific technical solutions are as follows. The clamping mechanism is polyurethane casters, which include the chassis and vertical moving parts. The components of its horizontal movement and clamping assembly are located on the chassis, the drive shaft is connected to the engine through the frame and installation, its vertical movement components and horizontal movement components are connected to the sliding plate of the clamping device assembly, the clamping device assembly is The front end is provided with a clamp and moves the part vertically so that the horizontally moving part can guide the clamp.
According to the prior art solution, the rotation of the drive shaft connected to the motor can cause the cam and the cam to rotate, and when the urethane caster component of the cam actuates the vertical movement element rotates, the horizontal movement component of the urethane caster component actuated by the cam rotates, The vertical movement component and the horizontal movement component at the same time, the action causes the gripper of the parts to be gripped, and operations are performed to grasp the application of these parts.
Pu Castor Wheels
It still has the elongation and resilience of rubber under high hardness. The hardness range of highly elastic polyurethane casters is Shore A10-D80. high strength. Under rubber hardness, their tearing strength, tearing strength, and load-bearing capacity is much higher than general rubber. Under high hardness, its impact strength and bending strength are much higher than plastic.
High strength, high heat resistance, 30-50℃ higher than ordinary polyurethane heat resistance. The nano-polyurethane elastomer developed and produced by our factory has good strength and wear resistance, heat resistance, hydrolysis resistance, aging resistance, and Good, it is a new generation of heat-resistant polyurethane elastomer. It can be applied to work under harsh conditions such as high temperature and high speed that ordinary polyurethane products are difficult to adapt to; such as oil drilling mud pump cups, high temperature, and high-pressure polyurethane seals, drawing rollers in textile machinery, textile high-speed wheels, high-speed friction Disk (film), roller film, etc.
Polyurethane is an emerging organic polymer material, known as the "Five Plastics", with good oil resistance, toughness, abrasion resistance, and aging resistance.
Polyurethane casters have the advantages of wear resistance, weather resistance, hydrolysis resistance, impact resistance, oil resistance, and strong tensile strength, tear strength, etc. Compared with ordinary rubber, this repair advantage has strong mechanical strength It is two to three times that of natural rubber. Its wear resistance is five to ten times that of natural rubber. It has strong compression resistance. It still has high elasticity at high hardness, which is not available in other rubbers. It is suitable for Welding processing of stainless steel cylinder and uses in the wind tower production line.
