What is the difference between a drum tooth coupling and a roller chain coupling?

For the drum tooth coupling and roller chain coupling many people are not very clear about the difference between the two, resulting in the use of the wrong product to bring a certain impact on the operation, so in order to help you understand the difference between the two, the following we introduce the difference between the drum tooth coupling and roller chain coupling.

What is the difference between a drum tooth coupling and a roller chain coupling?

1. Different structure

Roller chain coupling: The use of a common double-row chain and two parallel sprockets of the same number of teeth at the same time to achieve the connection of two half chain couplings.

Drum tooth coupling: two shells with internal teeth, two sleeves with external teeth, the same number of teeth, the external teeth into a spherical top of the waist drum shape. The shaft sleeve is connected with the shaft by a key, and the two shells are connected by bolts. Both ends are sealed, and the oil is stored in the cavity.

2. Different advantages

Chain coupling: the advantages are simple structure, compact size, small quality, convenient installation and disassembly, easy maintenance, low cost, and certain compensation performance and buffer performance.

Drum gear coupling: large transmission torque, can compensate the comprehensive displacement.

3. Different disadvantages

Chain coupling: The disadvantage is not suitable for reverse transmission and start frequently or vertical shaft transmission, not suitable for high-speed transmission.

Drum gear coupling: the disadvantage is that the structure is bulky and the cost is high.

4, the application range is different

Chain coupling: suitable for low speed and light load occasions.

Drum gear coupling: Used in heavy transmission applications.

Through the above comparison of all aspects of the drum tooth coupling and roller chain coupling, I believe that everyone can understand the difference between the two, no matter when we choose to use the product, we must be clear about the characteristics of the product itself, so as to better complete the use of the product.
