Simple Coupling Structure

The coupling is used to connect two axes (active and driven) in different mechanisms to rotate and transmit torque together, and some couplings also have buffering, damping and improving the dynamic performance of the shafting.

The coupling consists of two halves, which are connected with the active shaft and the driven shaft respectively. Most of the general Power machine with the aid of coupling and working machines, Voss Push in Couplings is the mechanical product shafting transmission is the most commonly used connecting parts. Common coupling has diaphragm coupling, tooth type coupling, plum coupling, slider coupling, Voss Push in Couplings drum-shaped gear coupling, universal coupling, safety coupling, elastic coupling and snake spring coupling.

Coupling function and type

Function: When the shaft and shaft to connect to convey power, generally useful pulley or gear to do the joint, but if the two axes to be on the line and require constant speed rotation, you must use the coupling to join. and due to the addition of precision, Voss Push in Couplings axial heating expansion or operation of the axial force bending, etc., the concentricity between the two axes will change, so the coupling can be used as a bridge to maintain the dynamic transmission between the two shafts and to absorb the radial, angular and axial deviations between the two axes, Voss Push in Couplings thus prolonging the mechanical life and improving the quality of the machinery.

Coupling with the shaft, according to different forms can be divided into key connection, clamping-type connection and expansion ring connection, Voss Push in Couplings several forms have advantages but also have disadvantages. We introduce, convenient for the user to choose the connection form of coupling to reference, for better transmission.

1. Key connection: The transmission torque is big, the structure is simple, the cost is low, the space size is small, but the high speed rotates, its dynamic balance is not good. Key connections work in the same way as normal mechanical device keys.

2. Clamping-Type connection: simple structure, low cost, small space size. However, Voss Push in Couplings when the locking force is not enough, it will cause axial slipping between the coupling and the shaft. The clamping connection is through the fastening screws at both ends, the "opening" is closed, and the clamping torque is enlarged.

3. Expansion ring Connection: The transmission torque is big, the related processing size requirements are high, the structure is complex, the coupling volume is large. Voss Push in Couplings The work principle of the account ring clamping is: Locking through the end cover, when pressing the end cover, at the same time pressure tight the expansion ring, bulge ring and the outer ring, the shape is tapered, so when there is pressure, its inner ring will be pressed on the shaft, the outer ring pressure on the coupling sleeve. This completes the connection between the shaft and the coupling.
