Abstract
The utility model relates to a turning gear tool of a three-shafting vertical main pump motor rotor. An entire pump unit adopts a three-shafting structure; a motor is provided with a set of upper guide bearing; a set of lower guide bearing is arranged below a pump; the motor and the pump share a set of bidirectional thrust bearing which is located between the motor and the pump; a connecting shaft (2) and a rotor (10) are connected by a fixed nut (3); a guide pad (8) and the guide pad support (9) are combined and mounted at a shaft extension of the rotor(10); and the front end of the connecting shaft (2) is provided with a turning gear rod (6). In the utility model, the support problem of the rotor without the thrust bearing in the main pump motor is successfully solved, the turning gear before the no-load test of the main pump motor can be easily carried out; and after the no-load test, the motor is disassembled so as to check the thrust pad, and the thrust pad surface is not scratched.
Description
Technical field:
It is vertical main pump motor rotor hand turning tool that the utility model relates to three axles.
Background technology:
General four shafting structures that adopt of vertical main pump unit, motor and pump have respectively 2 cover bearings, and the middle flexible clutch that adopts connects, and wherein motor has independent thrust bearing, guide bearing assembly, and test can be installed separately.Due to some special occasions, vertical main pump unit total height has strict restriction, uses the vertical main pump unit of three shafting structures can effectively save space.Three axles are that vertical main pump motor only has a top guide bearing, and pump and motor share a set of thrust-guide bearing, and therefore, motor rotor cannot complete separately installation, jiggering.
The content of invention:
The purpose of this utility model is to provide a kind of special hand turning tool, for completing the work such as jiggering before installation, debugging, jiggering and the empty load of motor that three axles are vertical main pump motor rotor.The technical solution of the utility model is: a kind of three axles are vertical main pump motor rotor hand turning tool, whole pump group adopts three shafting structures, motor is with a set of top guide bearing, there is a set of lower guide bearing pump below, motor and pump share a set of bidirectional propulsion guide bearing between motor and pump, hold-down nut (3) is connected connecting axle (2) with rotor (10), guide shoe (8) is arranged on rotor (10) shaft extension place after supporting (9) combination with guide shoe, and connecting axle (2) front end is installed jiggering bar (6).
The effect of invention:
When main pump motor rotor is installed: main pump motor and the main pump employing mode that is rigidly connected, main pump motor and main pump require main pump motor rotor (10) to be required to meet condition before to group: 1. circular runout is less than 0.03mm, and 2. perpendicularity is less than 0.03mm.Mounting bracket (1), connecting axle (2), hold-down nut (3), locking nut (4), spherical roller thrust bearing (5), jiggering bar (6), guide shoe (8), guide shoe support jiggering after (9), solve smoothly the rotor supports problem of main pump motor without reasoning bearing, measure through dial gauge, rotor radial is beated, and perpendicularity meets installation requirement.Jiggering before the test of main pump motor no-load: connecting axle (2), hold-down nut (3), jiggering bar (6), joint hinge (7) are installed, and use crane to coordinate jiggering, easily jiggering, removes motor and checks thrust bearing shoe valve after no-load test, thrust bearing shoe valve surface is without scratching.

Embodiment:
Embodiment 1:
A kind of three axles are vertical main pump motor rotor hand turning tool, whole pump group adopts three shafting structures, motor is with a set of top guide bearing, there is a set of lower guide bearing pump below, motor and pump share a set of bidirectional propulsion guide bearing between motor and pump, and hold-down nut 3 is connected connecting axle 2 with rotor 10, as shown in Figure 2, guide shoe 8 is arranged on rotor 10 shaft extension places after supporting 9 combinations with guide shoe, and connecting axle 2 front ends are installed jiggering bar 6.
As shown in Figure 1, spherical roller thrust bearing 5 nut 4 that is locked is fixed on connecting axle 2, and spherical roller thrust bearing 5 is fixed on support 1.The present embodiment structure is installed jiggering for rotor.
Embodiment 2:
A kind of three axles are vertical main pump motor rotor hand turning tool, whole pump group adopts three shafting structures, motor is with a set of top guide bearing, there is a set of lower guide bearing pump below, motor and pump share a set of bidirectional propulsion guide bearing between motor and pump, hold-down nut 3 is connected connecting axle 2 with rotor 10, guide shoe 8 is arranged on rotor 10 shaft extension places after supporting 9 combinations with guide shoe, and connecting axle 2 front ends are installed jiggering bar 6.
As shown in Figure 3, joint hinge 7 is arranged on connecting axle 2 topmost.The present embodiment structure is for jiggering before no load test.
When main pump motor rotor is installed: its operation principle is for to support whole rotor by spherical roller thrust bearing 5, and then complete jiggering.As shown in Figure 1, connecting axle 2 is fixed on to armature spindle end by hold-down nut 3, support 1 is arranged on motor, then install successively fixing: spherical roller thrust bearing 2, locking nut 4, jiggering bar 6, as shown in Figure 2, guide shoe 8, guide shoe support 9 are installed, by jack, rotor are adjusted to motor center.Guide shoe surface is contacted to jiggering afterwards with motor-shaft extending, measure by dial gauge that rotor radial is beated and perpendicularity.After repeatedly adjusting, circular runout mean value is about 0.02mm, and perpendicularity is about 0.01mm, meets main pump motor and main pump to organizing front requirement.
Jiggering before motor no-load test: its operation principle is for to promote 0.1mm～0.3mm by crane by rotor, and rotor makes to form oil film between thrust bearing shoe valve and thrust collar.As shown in Figure 3, connecting axle 2 is fixed on to armature spindle end by hold-down nut 3, joint hinge 7 is arranged on to connecting axle top, jiggering bar 6 is installed, use crane that rotor is sling gently, jiggering, makes to form oil film between thrust bearing shoe valve and thrust collar, protection thrust bearing shoe valve.
