Overload bent plate chain drive
As a common power transmission device, the chain, through the design of a hyperbolic arc "chain", reduces friction and is used where the power is relatively large and the running speed is relatively slow. It has obvious advantages over belt drives, such as in tanks and pneumatic compressors. However, the transmission speed cannot be too fast because the chain is not as flexible as a belt.

Product Description
Machine Information
In machine tool transmission devices, commonly used transmission components include pulleys, gears, worm gears, gear racks, and ball screws. These transmission components connect the power source to the actuator or connect two actuators, which is called a transmission link. A series of sequentially arranged transmission components that constitute a transmission link is called a transmission chain.
Transmission chains usually include two types of transmission mechanisms: one type is a transmission mechanism with a fixed transmission ratio and direction, such as a fixed-ratio gear pair and a worm gear pair, which is called a fixed-ratio transmission mechanism; the other type is a transmission mechanism that can change the transmission ratio and direction according to processing requirements, such as a stepped gear transmission mechanism and a sliding gear transmission mechanism, which is called a shifting mechanism.
According to the nature of the transmission link, transmission chains can be divided into two categories:
1. Internal link transmission chain: The movement (rotation and linear movement) of the actuators it connects belongs to an independent complete movement according to motion analysis, so the relative motion relationship between the actuators has strict requirements. A transmission chain with this type of transmission link property is called an internal link transmission chain. Therefore, internal link transmission chains do not have uncertain or instantaneous changes in the transmission ratio, such as belt drives, chain drives, and friction drives. For example, when machining threads on a lathe, the threaded drive connecting the main spindle and the tool rest is an internal link transmission chain with strictly required transmission ratios, which ensures and obtains the required pitch of the thread.
2. External link transmission chain: This is a transmission chain that connects the motion source and the machine tool actuator. It enables the actuator to obtain predetermined speed movement and transmit a certain amount of power, but does not require a strict transmission ratio relationship between the motion source and the actuator. The change in the transmission ratio of the external link transmission chain only affects productivity and surface roughness, not the formation of the workpiece surface shape.
Chain Classification
Short-pitch roller chains for transmission, double-pitch roller chains for transmission, bush chains for transmission, heavy-duty bent plate roller chains, toothed chains for transmission, stepless speed chains, long-pitch conveyor chains, short-pitch roller conveyor chains, double-pitch roller conveyor chains, high-speed conveyor chains, and plate chains.
Chain Limitations
As a common power transmission device, the chain, through the design of a hyperbolic arc "chain", reduces friction and is used in places where the power is relatively large and the running speed is relatively slow. It has obvious advantages over belt drives, such as tanks and pneumatic compressors, but the transmission speed cannot be too fast because the chain is not as flexible as a belt.
