Problems solved by technology

At the same time, due to the unstable manual pouring process, the product quality is unstable and it is easy to cause product cracking. Therefore, the service life of existing polyurethane (TPU) elastomer components is generally 2 months, which is short
But the replacement of this element is troublesome, especially the replacement of the elastic element of the construction crane coupling is more complicated
High-altitude operations are required, which brings personal safety problems to equipment maintenance

Abstract

The invention relates to an anti-fatigue thermoplastic elastomer and a preparation method of a plum coupling element. The anti-fatigue thermoplastic elastomer is prepared from the following raw materials in parts by weight: 100 parts of a polyester elastomer, 10-30 parts of a thermoplastic elastomer, 2-5 parts of a wear-resistant agent, 0.3-0.5 part of a hindered phenolic antioxidant, 0.2-0.5 part of a phosphite antioxidant and 0.5-1.0 part of a lubricating agent. The invention also discloses the preparation method of the plum coupling element by applying the anti-fatigue thermoplastic elastomer. According to the invention, a novel elastomer material is used for replacing a polyurethane material, the disadvantages of internal heating and self-warming of the polyurethane material are overcome, the anti-fatigue property of the elastomer element is improved, and thus the service life of the elastomer element is prolonged. Compared with the existing thermoplastic polyurethane (TPU) elastomer element, the flex fatigue-resistance is significantly increased, and the service life is prolonged by 2-3 times.

Description

technical field [0001] The invention relates to a thermoplastic elastomer and a preparation method of a plum blossom coupling element thereof, in particular to a preparation method of a flex fatigue-resistant thermoplastic elastomer and a plum blossom coupling elastic body. Background technique [0002] The plum blossom coupling is also called the claw coupling, which is composed of two metal claw discs and an elastic element. The elastic element is placed between the two metal claws to connect the metal claws, compensate the relative displacement of the two axes, and play the role of vibration reduction and buffering. [0003] During the operation of the equipment, when the elastic element is damaged or fails, the metal claws of the two shaft sleeves will be brought together to transmit torque intermittently, which will lead to the failure of the safety control of the transmission system and equipment failure. Therefore, the elastic element is a key component of the plum b...
