Problems solved by technology

In most cases, interference and transition fit are used between the coupling and the shaft. When repairing and maintaining equipment, disassembling the coupling is an essential step. Generally, three-jaw pullers and other equipment are used for disassembly. Excessive force will cause damage to the outer circle of the coupling. Improper placement of the three claws will easily slip and cause damage to personnel or equipment. It is difficult to control, time-consuming and labor-intensive, and the safety is not strong.

Embodiment Construction

[0047] The specific implementation of the shaft coupling removal tool provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] see figure 1 , The coupling removal tool of the present invention includes a base 10 , an outer fixed disk 20 and at least two sets of inner fixed disks 30 .

[0049] The base 10 has at least two first connection holes 101 . The first connection hole 101 and the shaft coupling 60 (marked on Figure 7 ) on the pin hole 601 (marked on Figure 7 ) coaxial setting. The pitch circle of the first connecting hole 101 is the same as that of the pin hole 101 , and the diameter of the first connecting hole 101 is the same as the small end of the pin hole 601 . Further, the number of the first connection holes 101 is the same as the number of the bolt holes 601 , or half of the number of the bolt holes 601 . Preferably, in order to further enhance the detachment effect of the coupling removal...

Abstract

The invention provides a coupling dismounting tool. The coupling dismounting tool comprises a base, an outer fixing disc, two sets of inner fixing discs, and at least two screws. The screws penetrate through first connecting holes, second connecting holes, pin holes of a coupling, and third connecting holes. On the coupling side, the screws are fixed to the coupling side through nuts; and on the base side, a nut is connected with each screw, and the nuts can be unscrewed so that the coupling can be driven by the outer fixing disc and the inner fixing discs to be disengaged from a shaft. The coupling dismounting tool has the advantages that pump couplings and motor couplings can be dismounted safely, the situation that the couplings are damaged due to operation such as knocking, prying and hitting, and consequentially using and centering are affected is avoided, and the service life of the couplings is prolonged; the accidents that people are injured or the couplings are damaged due to operating instability of three-jaw pullers and the like can be avoided, and safe production is guaranteed; and operation is convenient and fast, time and labor are saved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a demounting tool for a pin type shaft coupling. Background technique [0002] Most of the couplings are used as the power transmission mechanism between the centrifugal pump and the prime mover. The elastic pin coupling is one of the widely used couplings due to its reliable performance, large transmission torque and convenient use. In most cases, interference and transition fit are used between the coupling and the shaft. When repairing and maintaining equipment, disassembling the coupling is an essential step. Generally, three-jaw pullers and other equipment are used for disassembly. Excessive force will cause damage to the outer circle of the coupling. Improper placement of the three claws will easily slip and cause damage to personnel or equipment. It is difficult to control, time-consuming and labor-intensive, and the safety is not strong. Contents of the invention [0003] The t...
