Description
Technical field
The utility model relates to a kind of dial indicator bracket, particularly relates to a kind of dial indicator bracket installing and measuring diameter run-out and face runout for locomotive diesel genset.
Background technology
In assembling diesel generator process in the past, diesel engine and main generator centering is needed to assemble, main generator is coupled together by joint flange, highly elastic shaft coupling and diesel engine flywheel, in centering assembling process, on the external diameter needing dial gauge gauge head to be placed in flywheel and end face, measure diameter run-out and face runout respectively.But in practical operation, first highly elastic shaft coupling is arranged on main generator spindle nose, assemble with diesel engine centering again, be subject to the restriction of assembling space, by indicator bracket on highly elastic shaft coupling, because highly elastic shaft coupling rubber bodies is flexible, can only will affect the precision of centering, bring very large trouble to on-the-spot operation, and the reliability of diesel generator set work can be affected.
In prior art, joint flange is arranged on main generator spindle nose by tapering interference fit, and highly elastic shaft coupling is connected with joint flange by bolt, and highly elastic shaft coupling, when being connected with diesel engine flywheel, needing and assembles after diesel engine flywheel centering.During assembling, dial gauge should be adsorbed on main generator rotor axle, on the circular radial side face that dial gauge gauge head is placed at diesel engine flywheel respectively and on end face, rotate main generator rotor axle, measure diameter run-out and the face runout of flywheel, measuring accuracy reaches 0.01mm.Because the gap between main generator and joint flange is too little, dial gauge directly can not be adsorbed on main generator spindle nose; As being adsorbed on joint flange by dial gauge, joint flange is less, and built on the sand, meanwhile, the bearing pole of dial gauge standard falls short of, and dial gauge gauge head can not contact with diesel engine flywheel, therefore can not measure in dial gauge absorption.Be subject to space structure restriction, dial gauge can only be adsorbed on highly elastic shaft coupling shell, but because highly elastic shaft coupling inner structure is elastic rubbery body, armature spindle is in drive highly elastic shaft coupling rotary course, highly elastic shaft coupling is subject to self gravitation impact, elastic caoutchouc cognition deforms, and affects measuring accuracy.In adjustment centering process, each measuring error is about 0.2mm.
The shortcoming of prior art is: in assembling diesel generator process, highly elastic shaft coupling is subject to self gravitation impact, and inner rubber knows from experience generation plastic yield, affects accuracy of alignment, cause main generator rotor axle and crankshaft of diesel engine decentraction, or installation end face tilt produces additional force.During diesel generator set normally works, crankshaft of diesel engine drives main generator rotor axle to rotate, and twisting vibration amplitude can be made to increase, and the vibration severity of diesel generator set also can correspondingly increase, and reduces the serviceability of diesel generator set, and the machine that even can produce breaks.
Utility model content
The technical matters that the utility model solves is for avoiding the plastic yield of highly elastic shaft coupling rubber bodies to affect centering assembly precision, a kind of dial indicator bracket of rigidity is proposed, be directly installed on main generator spindle nose, dial gauge is adsorbed in the plane of this support, improve the stability of absorption, dial gauge can rotate with main generator rotor axle, measures diameter run-out and the face runout of flywheel, improve accuracy of alignment, reduce the twisting vibration of diesel-driven generator.
This dial indicator bracket, diesel engine flywheel is connected with main generator with joint flange by highly elastic shaft coupling, joint flange and main generator spindle nose tapering interference fit, highly elastic shaft coupling is connected by bolt one with joint flange, highly elastic shaft coupling is connected by thru-bolt with diesel engine flywheel, dial indicator bracket is arranged on main generator spindle nose root, dial indicator bracket upper body is connected by bolt two with dial indicator bracket lower body, dial gauge is connected with dial indicator bracket by bearing pole, and dial gauge gauge head contacts with diesel engine flywheel.
On described dial indicator bracket, shape is inverted Y.
Described dial indicator bracket lower body is arc-shaped.

Embodiment
Below in conjunction with accompanying drawing, dial indicator bracket is further described.
This dial indicator bracket, diesel engine flywheel 1 is connected with main generator with joint flange 3 by highly elastic shaft coupling 2, with hydraulic pressure expanding device, joint flange 3 spreading is arranged on main generator spindle nose 4, joint flange 3 and main generator spindle nose 4 tapering interference fit, highly elastic shaft coupling 2 is connected by bolt one with joint flange 3, highly elastic shaft coupling 2 is connected by thru-bolt with diesel engine flywheel 1, dial indicator bracket 5 is arranged on main generator spindle nose 4 root, make the connection of dial indicator bracket 5 for being rigidly connected, bearing pole 9 length carried due to dial gauge and the space constraint between main generator spindle nose 4 and joint flange, dial indicator bracket 5 is provided with the height that dial indicator bracket upper body 6 and dial indicator bracket lower body 7 increase dial indicator bracket 5, thus dial gauge side 10 can be contacted with diesel engine flywheel 1, dial indicator bracket upper body 6 is connected by bolt 28 with dial indicator bracket lower body 7, dial gauge is connected with dial indicator bracket 5 by bearing pole 9, dial gauge gauge head 10 contacts with diesel engine flywheel 1.Dial indicator bracket lower body 7 is arc-shaped, in order to fit with main generator spindle nose, dial indicator bracket lower body 7 is designed to flexible arc-shaped, material is the diaphragm that 5mm is thick, the contact area of diaphragm and main generator spindle nose 4 can be adjusted, steady support better with the profile of main generator spindle nose 4.The Liang Ge branch on the top of " Y " of dial indicator bracket upper body 6 is provided with prong 61, and prong 61 is provided with groove 62.For improving the versatility of dial indicator bracket 5, to be applicable to the main generator spindle nose 4 of different-diameter, at the two ends of dial indicator bracket lower body 7, respectively rotating dog 71 is installed, bolt 28 one end also freely can be rotated around rotating dog 71 central shaft through rotating dog 71, a straight pin 72 is screwed at bolt 28 thread end, first bolt 28 is pushed the prong 61 of dial indicator bracket upper body 6, slide for preventing straight pin 72 and come off, at prong 61 place design groove 62, straight pin 72 is made to press close to groove 62, and screwing bolts 28, tight dial indicator bracket upper body 6 and dial indicator bracket lower body 7.When main generator spindle nose 4 diameter is different, angle between bolt 28 and vertical plane is also different, straight pin 72 is understood the angle of inclination of fitted bolt 28 and rotates certain position, remain and to contact with the groove line of dial indicator bracket upper body 6, make bolt 28 be in the state of not stressing, be convenient to install tight.
Before highly elastic shaft coupling 2 connects diesel engine flywheel 1, by dial gauge gauge head 10 and diesel engine flywheel 1 circular radial circumferential contact, rotate main generator rotor axle, drive dial gauge measure diesel engine flywheel 1 up and down and the diameter run-out of left and right, make the center of the center of diesel engine flywheel and main generator in same level.Then highly elastic shaft coupling 2 is connected with joint flange 3 bolt one, by the end contact of dial gauge gauge head 10 with diesel engine flywheel 1, rotate main generator rotor axle, drive dial gauge rotates, measure the upper and lower of diesel engine flywheel 1 and left and right face runout, be the end face of diesel engine flywheel 2 and the end face keeping parallelism of main generator, thus the centering realizing diesel engine and main generator is assembled.
The connection of dial indicator bracket 5 and main generator spindle nose 4 is for being rigidly connected, and improve measuring accuracy, each measuring error is 0.01mm, avoids repeating adjustment and measures, improve work efficiency.
