The basic types of chain
Tell you small make up the chain of basic types of agricultural machinery chain
According to different, use chain can be divided into three types of lifting chain, traction chain and transmission chain. Lift weights in the lifting chain is mainly used for hoisting machinery, its work speed v 0.25 m/s or less; Drag chain is mainly used for moving heavy objects in the chain conveyor, its work speed v 4 m/s or less; Used in general mechanical transmission chain transfer movement and power, usually working speed v 15 m/s or less.
Transmission chain, which has two kinds of tooth shape chain and roller chain. Tooth shape chain is the use of a specific tooth profile of chain and sprocket meshing transmission, as shown in figure 9-2. Tooth shape chain drive is smooth, the noise is small, so it is also called silent chain drive. Tooth shape chain allows the working speed of up to 40 m/s, but the manufacturing cost is high, the weight is big, so the more used in high speed or sport requiring higher precision.
Mainly used for power transmission chain with sleeve roller chain and tooth shape chain of two. Sleeve roller chain chain plate from within and outside the chain plate, sleeve, pin shaft, roller. Inside outside the chain plate fixed on the pin shaft, roller chain plate is fixed on the sleeve, between the roller and the sleeve and the sleeve and the pin shaft, are relative rotation between and the chain and sprocket meshing to rolling friction. The sleeve roller chain can use single and multiple columns and, more columns and can deliver higher power. Sleeve roller chain than tooth shape chain light weight, long life and low cost. Widely used in power transmission.
Tooth shape chain is more than with a pin shaft with 60 ° Angle of working face chain assembled. Working face engages with sprocket chain parts. In order to prevent the chain from the chain at work, and the chain is equipped with guide within or outside the guide. When meshing guide with corresponding guide chimeric sprocket. Tooth shape chain drive is smooth, the noise is small, so it is also a silent chain, often used in high speed transmission. Sleeve roller chain and sprocket tooth shape chain of the tooth profile should guarantee the energy-saving freedom to enter or exit the mesh chain, against the trendy impact is small, good contacts in the mesh.
