Description

Adjustable centering tool for coupler

Technical Field

The utility model relates to an adjustable nodal pattern shaft coupling centering instrument belongs to shaft coupling equipment technical field.

Background

Alignment of the coupling is one of the important tasks in the mounting of the coupling, and is particularly important for high-speed running equipment.

A currently common method is dial gauge measurement. A special clamp (a pair of wheel clamps) or a magnetometer is arranged on a half coupling which is used as a reference (usually arranged on a main machine rotating shaft), and a dial indicator is used for measuring the deviation value of the radial clearance and the axial clearance of the coupling.

The method comprises the specific steps of firstly using an angle square to preliminarily measure and adjust a coupler on a machine with a hoisting _ level ready to be adjusted. Then, a special fixture and a dial indicator are arranged on the main machine side half coupling serving as a reference, and the contact of the dial indicator points to the excircle and the end face of the main machine side half coupling. When measuring, firstly, the radial reading a1 and the axial reading s1 of the 0-degree orientation are measured. For the convenience of analysis and calculation, the values of a1 and s1 are usually adjusted to zero, then the coupling halves are rotated simultaneously, the values in the table are read every 90 degrees, and the read values are filled in the record chart. The radial readings a1, a2, a3, a4 are recorded outside the circle, and the axial readings s1, s2, s3, s4 are recorded inside the circle, which coincide with the original zero readings when the dial indicator is rotated back to zero. The measured reading is correct if a1+ a3= a2+ a 4; s1+ s3= s2+ s4 determines the relative position of the two axes in space by analytical calculation of the measured values, and then adjusts the relative positions according to the calculation result. At present, a centering tool generally adopts a method of matching a magnetic gauge stand with a dial indicator to measure centering data. The magnetic gauge stand measurement has the defects that 1, the installation is not firm, and errors exist in reading, so that the measurement is inaccurate; 2. the magnetic gauge stand needs to be installed and adjusted every time the centering work is carried out, and time is consumed; 3. for a coupler with a larger gear between the wheels, a lengthened magnetic meter rod is also needed, so that time is consumed and the reading accuracy is influenced; 4. after the magnetic gauge stand is used for many times, the magnetic gauge stand is easy to damage, generates larger errors and has insufficient precision.
