Discussion on the adjustment method of coupling timing

Adjustment method of coupling alignment;

When adjusting the coupling, the axial clearance is usually adjusted first to make the two halves of the coupling parallel, and then the radial clearance is adjusted to make the two halves coaxial. In order to adjust the coupling accurately and quickly, the following approximate calculation should be made to determine the thickness of the gasket that should be increased or decreased at the bottom of the main engine.

A mechanical part is used to firmly connect the driving shaft and the driven shaft in different mechanisms, so that they can rotate together and transmit motion and torque. Sometimes it is also used to connect shafts and other parts (such as gears and pulleys).

It usually consists of two parts, which are connected by a key or tight fit, fastened at the ends of two shafts, and then connected in some way. The coupling can compensate the deviation (including axial deviation, radial deviation, angular deviation or comprehensive deviation) between the two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during operation. As well as shock absorption and vibration absorption.

Extended data:

The mobility of coupling refers to the ability to compensate the relative displacement of two rotating members. Factors such as manufacturing and installation errors between connecting parts, temperature changes during operation and deformation under load all require mobility. Movable performance compensates or alleviates the extra load among shafts, bearings, couplings and other parts caused by relative displacement between rotating parts.

Selection of coupling type When selecting coupling type, the following items should be considered.

1, the magnitude and nature of the required transmission torque, the requirements of buffering and vibration reduction functions, and whether * * * vibration is possible.

2. The degree of relative displacement between two shafts caused by manufacturing and assembly errors, shaft load, thermal expansion and deformation, and relative motion between parts.

3, allow the size and installation method, in order to facilitate the assembly, adjustment and maintenance of the necessary operating space. For large couplings, the shaft should be able to be disassembled and assembled without axial movement.
