Driving roller chain
In modern production, drive technology is widespread, in which an important role is played roller chains. They transfer the mechanical energy of the drive shaft to the driven shaft. In addition to applications in oil production equipment, agricultural and construction equipment, such chains are used in motorcycles, bicycles and cars.
Drive chains have many advantages over belts. They do not slip due to the reliable coupling of sprockets and chains, have high efficiency and can transmit rotation up to 7 m. At the same time, there is no initial tension, which adds load to the shaft and bearings. Chains work equally well at high and low temperatures. Another important plus of drive chains is the ease of replacement and the ability to adjust the length of the chains by adding or removing links.
However, there are a number of drawbacks. These include, first of all, the wear of the components of the chain - as a result, the drive chain is stretched and additional noise appears during its operation. Also noteworthy is the difficulty in lubricating the hinges of the chain.
Consider the circuit design:
- inner plate
- roller
- outer plate
- roller
- sleeve
Internal and external links form swivel joints with bushings and rollers. The rollers in the process of the chain "fall" between the teeth of the asterisks, thereby perceived or transferring effort.
In order not to be mistaken with the choice of the chain, it is necessary to know the distance between the inner plates and the chain pitch (the distance between the geometric centers of the adjacent rollers). Breaking load on the gap - also a required parameter that must be considered when selecting. Its value is determined experimentally.
On the website of the company MIC-Bearing, you can find one- and two-row chains, as well as connecting and transitional links. A convenient catalog and key features will help you quickly and easily find the right position.
