For example, how to determine the center distance between the rollers of a double chain tooth drive roller conveyor? Of course, the center distance should be initially determined according to the structural requirements. However, the center distance required by the structure does not necessarily match the results of the chain link length calculation, so it is necessary to adjust the center distance according to the actual number of chain links in turn after the calculation is completed...

The chain enters the sprocket and forms a folding line, so the movement of the chain drive is very similar to the belt drive around a positive polygon wheel, see Figure 9. The side length is equivalent to the chain pitch p, and the number of sides is equivalent to the number of teeth of the sprocket z. The distance the chain moves for each week of the sprocket is zp, let z1 and z2 be the number of teeth of the two sprockets, and p be the pitch...

Correct use and maintenance of the chain drive has a decisive influence on reducing the wear and tear of the chain and improving the service life of the chain drive. The use and maintenance should pay attention to the following points: 1. Reasonable control of processing error and assembly error Reasonable control of pitch error (the difference between the specified pitch and the actual pitch) should be less than 2%; two sprocket wheel teeth end...

1、The arrangement of the chain drive The chain drive should generally be arranged in the plumb plane, as far as possible to avoid the arrangement in the horizontal or inclined plane. If it is necessary, it should be considered to add pallets or tensioning wheels and other devices, and design a more compact center distance. 2、Tensioning of the chain drive Purpose: To avoid the chain from draping too much...

1、Protection of mechanical transmission mechanism hazards Transmission device requires shielding all moving parts to isolate any part of the body from contact with it. According to the shape of the protection part, the size of the fixed protection device made, installed in the transmission part of the external, can be completed to prevent human contact with the dangerous parts of the rotation of the machine. Main protection...

With the continuous innovation of industrial conveyor sprocket technology in industrial conveying machinery and equipment, the industrial sprocket on conveyor conveying equipment has also been more widely used, and the use of a variety of types of conveying equipment, according to the production environment and place of different enterprises and production process technology, to carry out a variety of conveying equipment...
