Features of encoder coupling

The encoder coupling is a coupling specially used to connect the motor and the encoder. Encoder couplings usually need to have the following characteristics:

1. Zero clearance: the entire coupling is not allowed to have any clearance during the transmission process;

2. Low inertia: on the basis of ensuring the transmission strength, the weight of the encoder coupling should be reduced as much as possible;

3. Good elasticity: The precise encoder coupling needs to absorb the deviation between the shaft and the shaft produced in the installation process to a large extent;

4. Compact structure: The encoder coupling is usually small in size, and its clockwise and counterclockwise rotation characteristics are exactly the same;

5. Maintenance-free: After the coupling is installed, there is basically no need for maintenance, and the installation is extremely convenient.

To distinguish different encoder couplings, we can roughly divide them into four types:

1. Aluminum alloy encoder coupling;

2. Stainless steel encoder coupling;

3. Bellows encoder coupling;

4. Polyurethane encoder coupling.

The production of these four types is distinguished by the material of the coupling. And because of the different materials made, the nature of the encoder coupling produced, and the main applicable occasions are also different.

But they all have some necessary features of encoder couplings, for example, the structure is very compact during the rotation of the coupling, there is no gap, and it has relatively good mechanical properties and low inertia; and It is a precision instrument, so its flexibility is relatively good. An advantage that people pay more attention to is that the maintenance process of the encoder coupling is almost non-existent during use. So it is very time-saving and labor-saving, which makes it more popular in the market.
