Timken high-strength polyester elastomer material coupling

Timken high-strength polyester elastomer material coupling - 2020 09 - 30 ( Timken) Coupling is used to join different structure of the driving shaft and driven shaft of joint rotation and torque of mechanical parts. The overloaded power transmission at high speed, some coupling and buffer, vibration and enhance the role of shaft system dynamic performance. Coupling of various kinds, including coupling, oldham coupling, universal coupling and elastomer coupling, etc. For power transmission industry, compared to the more common type coupling, elastomer coupling is not widely understood. In fact, the elastomer coupling with the special material properties and has a unique advantage. According to different, elastomer mechanical elastomer couplings can be divided into shear and compression. This article focuses on shearing Timken® 快速的, Flex® Upgrade the elastomer coupling elastomer material through innovative and diversified design a new option for power transmission devices. 铁姆肯公司® 快速的, Flex® Four features beyond type coupling elastomer coupling in a lot of processing industry, grease lubrication of tooth coupling can be seen everywhere. Type coupling although effective and principles to understand, but type coupling is obviously better than the elastomer coupling in the following aspects. 1. Predictability: many tooth type coupling gear ring will wear long running due to lead to equipment failure ( See figure 1) 。 To determine the residual life must be disassembled greasy coupling, this will directly affect the downtime. And elastomer coupling between tooth mesh by high-strength elastomer, elastomer is the only withstand wear parts, can effectively buffer when shock and vibration, and by more than one rating of high torque automatically cut off, so as to protect the equipment from being damaged. Figure 1 tooth damage coupling of the two. Change is simple: type coupling once cannot work normally after wear and tear, nor gear ring part replacement, must change into a new type coupling; And replace the complicated process, the cost is high. And coupling elastomer replacement is simple a lot. Bossing without replacement, motor, gearbox and other parts also don't need to be replaced because of the coupling and dismantling, high-strength polyester elastic block only needs to be replaced. Only when the replacement down cover, remove from two bossing elastic block, and then according to the steps to install the new elastic block to the contrary, can be completed quickly replaced. Figure 2 in disassembly type coupling fault happened later had to adopt the way of flame cutting, a big increase in the coupling of process time and cost. 3. Non-lubricated: type coupling shaft eccentricity running need grease, should add grease must suspend coupling work, increase the downtime. And elastomer coupling USES high-strength polyester elastic block, without lubrication, also won't produce grease filling and cleaning cost. 4. Can be customized: type coupling has a unique maximum torque value, and the same size of the elastomer coupling can be used according to the internal elastic block of different hardness and with different levels of the maximum torque value, in the application can be according to the scope of elastomer coupling size for a particular equipment and application condition of customized coupling scheme. In addition, you can provide smaller equivalent coupling solution to enhance the flexibility and cost savings. Solve customer problem before using elastomer coupling, a certain open-pit mining factory of the failure of tooth coupling power shovel often happen, As shown in figure 1, figure 2) , causing unplanned downtime and huge economic losses. Timken engineer suggested that it will be easy to fault coupling elastomer couplings instead. To address that people generally think of elastomer coupling not better than type coupling of misunderstanding, according to customer's demand, timken torque to customize a Timken® 快速的, Flex® Coupling. The installation of the trial process, simple and highly effective and excellent product performance is very satisfied with the customer. Soon, the mine decided to replace other with elastomer coupling in type coupling with excavator. As the market's expectations of equipment performance and economic benefit, elastomer coupling the advantages of more and more prominent. Especially in the condition of application, the elastomer coupling with easy to install, no lubrication, durable, easy maintenance features are conquer more and more users.
