The roller chain looks like a tank chain and is composed of many unit links. The links can rotate freely. The inner height, outer height, and pitch of the same series of plate chains are the same. The inner width and bending radius of the drag chain can be different. ,The unit chain link is composed of left and right chain plates and upper and lower cover plates. Each link of the drag chain can be opened. It is convenient to assemble and disassemble without threading. After opening the cover, you can put cables, oil pipes, air pipes, water pipes, etc. into the drag chain. Separator can be provided to separate the space in the chain as needed. We can increase the air humidity of the working place and the room to reduce the generation of static electricity; it is to increase the grounding wire on the machine and equipment to introduce the static electricity into the earth in time;
The error of the transmission chain will affect the correctness of the tool movement. In some cases, it is the main factor that affects the machining accuracy. For example, when hobbing gears, the ratio of the rotating speed of the hob to the rotating speed of the workpiece needs to be constant, maintaining a strict movement relationship.
When the transmission elements in the transmission chain (such as hobbing change gears, indexing worm gear pairs, etc.) have manufacturing errors and assembly errors, and wear during use, the correct movement relationship will be destroyed and the rolled out gears will be produced. Errors (such as section error, cumulative error of the section and tooth profile error, etc.). Therefore, the transmission accuracy of the machine tool transmission chain firstly depends on the manufacturing and assembly accuracy of each transmission element, and secondly it is related to the position of each transmission element in the transmission chain.
Conveyor chain, as a common transmission power device, uses a hyperbolic arc "chain" design to reduce friction. It is used in places where the power is relatively large and the running speed is relatively slow. It has obvious advantages over belt transmission, for example Tanks, pneumatic compressors, etc., but the transmission speed cannot be too fast, because the flexibility of the chain is not as good as the belt transmission. It is composed of inner chain links and outer chain links. It is composed of five small parts: inner chain plate, outer chain plate, pin, sleeve and roller. The quality of the chain depends on the pin and sleeve.
The standard drive roller chain is a general drive roller chain based on JIS and ANSI standards. The plate chain is a hanging chain composed of chain plates and pins. Stainless steel chain is a stainless steel chain that can be used in special environments such as medicine, water and high temperature. The standard accessory chain is a chain with accessories attached to the standard roller chain for transmission. The hollow pin chain is a chain connected by hollow pins, and accessories such as pins, cross bars, etc. can be added or removed freely according to customer requirements.
