Abstract

The utility model discloses a testing device of a small-movement single-bearing main generator. The testing device comprises a main generator stator assembly and a main generator rotor assembly; the main generator stator assembly is connected with a bearing limiting device, an elastic connector and a tractor rotating shaft of a test table in sequence through a transition device; an aperture of an elastic column pin hole of a coupler at the left side of the elastic connector is more than an aperture in standard design; and the bearing limiting device is provided with a bearing with a smaller axial movement. The main generator testing device provided by the utility model has the advantages as follows: the testing device not only can support the rotor assembly of the small-movement single-bearing main generator so that the position of the small-movement single-bearing main generator can be varied along with the position variation of the main generator, but also has low requirement on repeatability between an axis of the main generator and an axis of a tractor, thereby preventing the generator bearing from being burnt through a continuous and overlarge axial force in a testing process. Meanwhile, the small-movement main generator is convenient to erect; the working capacity of staff can be reduced; and the production efficiency is improved.

Description

Little shifting amount single shaft holds the main generator test unit
Technical field
The utility model relates to a kind of little shifting amount single shaft and holds the main generator test unit.
Background technology
Past, the stator assembling of main generator was installed on the erecting frame of stationkeeping by rigidity ground when single shaft was held main generator and makes an experiment, and direct employing rigidity ways of connecting between the rotating shaft of rotor assembling and pull-over gear.In the main generator installation process, the relative axial position between stator assembling and the rotor assembling need not adjusted.
When adopting mounting means in the past that main generator is made an experiment; The scope of the axial float of requirement rotor assembling is relatively large; And former many moneys main generator allows the axial movement value of rotor assembling can reach 8mm; Therefore, former test unit can guarantee the requirement of generator test to the motor shifting amount like a cork, and can not cause any harmful effect to the bearing operation of main generator.But some single shaft is held main generator;, be not more than 0.6mm, if still adopt original test unit that little shifting amount main generator is made an experiment because but the range of size of the axial play of its rotor assembling is very little; Then when motor is installed; The bearing of generator will inevitably can receive very big axial force, adds the huge electromagnetic force that occurs in the generator operation process, the bearing of generator can because in process of the test, continue, excessive axial force and scaling loss.
The utility model content
The utility model has overcome shortcoming of the prior art, provides a kind of little shifting amount single shaft to hold the main generator test unit, is used to solve shifting amount is held main generator less than the single shaft of 1mm test.
The technical scheme of the utility model is: a kind of little shifting amount single shaft holds the main generator test unit; Comprise main generator unit stator assembling and main generator rotor assembling, said main generator rotor assembling is connected with bearing stop means, elastic connector with the pull-over gear rotating shaft of testing table successively through transition apparatus and links to each other.
Said elastic connector comprises left and right two shaft couplings, spring column pin and rubber rings, and the aperture of the post pin-and-hole of left side shaft coupling is bigger than the aperture of standard design; The shaft coupling on the said bearing stop means left side links to each other with the shaft coupling of rubber ring with elastic connector the right through spring column pin.
Said bearing stop means comprises the bearing that bearing seat, bearing chamber and axial movement value are less.
Said main generator rotor assembling links to each other through the terminal pad rigidity with transition apparatus, and said transition apparatus links to each other with bearing stop means rigidity through shaft coupling.
Compared with prior art; The utility model has the advantages that: through between pull-over gear rotating shaft and main generator rotating shaft, increasing elastic connector and bearing stop means; Not only can support the rotor assembling that little shifting amount single shaft holds main generator; Its position can change with the change in location of main generator, and less demanding to the axis and the repeatability between the pull-over gear axis of main generator, avoids dynamo bearing in process of the test, to receive lasting, excessive axial force and scaling loss.Simultaneously, the frame of little shifting amount main generator dress is convenient, can reduce the employee work amount, enhances productivity.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of the utility model.
Embodiment
A kind of little shifting amount single shaft holds the main generator test unit; As shown in Figure 1; Comprise: main generator unit stator assembling 1, main generator rotor assembling 2, elastic connector 3, bearing stop means 4, transition apparatus 5, test base 6, test circular arc seat 7, exciter stator assembling 8 and exciter rotor assembling 9 etc., wherein:
Main generator unit stator assembling 1 among Fig. 1, main generator rotor assembling 2, exciter stator assembling 8 and exciter rotor assembling 9 etc. are by the critical piece of test main generator; Test base 6 is used for fixing underproof main generator with test circular arc seat 7; The terminal pad of transition apparatus 5 right-hand members assembles 2 rigidity with main generator rotor and links to each other; The shaft coupling of transition apparatus 5 left ends links to each other with the shaft coupling rigidity on bearing stop means 4 the right; The shaft coupling on bearing stop means 4 left sides links to each other with the shaft coupling of rubber ring with elastic connector 3 the right through spring column pin, and the shaft coupling on elastic connector 3 left sides links to each other with the former pull-over gear rotating shaft of testing table.In this test unit, elastic connector 3 and bearing stop means 4, two shaft couplings, spring column pin and rubber rings about elastic connector 3 comprises have been used in new design; Spring column pin and rubber ring are standard component; And the aperture of the post pin-and-hole of left side shaft coupling is bigger than the aperture of standard design, use this elastic connector after, the accuracy requirement of main generator installation site is reduced; Be convenient to dismounting simultaneously, increase work efficiency.Bearing stop means 4 comprises the bearing that bearing seat, bearing chamber and axial movement value are less, is used to support the rotor assembling of main generator, and the axial location of adjustment main generator rotor assembling guarantees that the bearing that the back main generator is installed can not receive axial force.
