Parkinson gear tester is used to test the error in the gear. Here the carriage has two spindle. One main gear is fixed in one spindle and another testing gear is. Head of the Department Principal Certificate of Undertaking We, hereby declare that project entitled AUTOMATION OF PARKINSON GEAR TESTING MACHINE. 4 Apr Development of Parkinson gear tester for spur gear to check the Flank Surface being compact and portable equipment, which is skilful and is.

A circle is drawn at the same time as the record as shown in figure Creating downloadable prezi, be patient.

View my complete profile. The right mandrel slide is free to move, running on steel ballsagainst spring pressure and it has a limited movement. Permanent records can be obtained on charts, and on analysis any modifications in existing manufacturing setup can be made if required any. Parkinson gear tester gives the reading using standard gear and dial gauge. These links and information displayed here are used by me during engineering for term work, seminars and projects.

The principle of this device is to mount a standard gear on a fixed vertical spindle and the gear to be tested on another similar spindle mounted on a similar spindle mounted on a sliding carriage, maintaining the gears in mesh by spring pressure. Movements of the sliding carriage as the gears are rotated and indicated by a dial indicator, and these variations are a measure of any irregularities in the gear under testalternatively a recorder can be fittedin the form of a waxed circular chart and records made of the gear variation in accuracy of mesh.

Disadvantages Generally 80 mm max diameter of gear can be measured as per our setup. Errors are not clearly identified for type profile, pitch, helix, tooth thickness, indistinguishably mixed. As the gear rotate the movement of the sliding carriage is indicated by the dial indicator. The master gear is mounted as an adjustable carriage whose position can be adjusted to enable the wide range of gear diameters to be accommodated and it can be clamped in any desired position.


This model can be modified by adding recorder or any other electronic device. Neither you, nor the coeditors you shared it with will be able to recover it again. Gear tester for testing Spur gears Thank You!!! These gears are maintained in mesh by a spring. Present to your audience Start remote presentation.

To determine the variations in gear manufacturing machines and take corrective measures for the same. Houston, we have a problem! Gears used in the setup Quality of Gear profile wrt Dial gauge reading Costing Conclusion A gear tester for measuring the dimensions of gear is successfully made. Located in Hazel Park, Michigan. When the waxed paper recorder is fitted, the chart makes a revolution for each one of parkimson gears mounted on the sliding carriage. The gears are mounted on the two mandrelsso that they are free to rotate without measurable clearance.

Composite errors can be checked by measuring the variations of center distance when gear under test is rolled under spring pressure against master gear.

Gear Manufacturing (By Cutting): Parkinson Gear Tester

Constrain to simple back and forward pxrkinson. Thus, movements of the carriage, as indicated to the dial gauge, show the errors in the gear under test. Present to your audience. Detect errors in concentricity of pitch line. Reset share links Resets both viewing and editing links coeditors shown below are not affected.

Parkinson Gear Tester by Rahil Shah on Prezi

Alternatively a recorder can be fitted in form of a circular chart and records can be obtained of the gear variations. About Me Nicks hi. Metrology Such testers are also available, for bevel, helical, worm gears. Parkinson gear tester is one of the measuring instrument for gear profile measurement. When these gears are in close mesh and rotated any errors in the tooth form, pitch or concentricity of the pitch line, will cause a variation in center distance.

The gears under test are mounted on a floating spring loaded carriage so that the master gear and the gear under test may be meshed together under controlled spring pressure. Copy code to clipboard. Delete comment or cancel. When two gear are in closed meshed and rotated, any error in the tooth formpitch or concentricity of pitch line will cause a variation in center distance. The master gear is mounted on an adjustable carriage so that its position can be adjusted in order accommodate wider ranges of gear and it can be clamped in any desired position.

Please log in to add your comment. There is low friction in movement of floating carriage and a high sensitivity of sensing unit is important.

And this variation is measure of any irregularities of the gear to be tested. The gear under test is mounted on a floating spring loaded carriage so that the master gear and the gear under test may be meshed together under controlled spring pressure. For gear profile measurement different types of instruments are used.

The two mandrels can be adjusted so that their axial distance is equal to the designed gear center distance.

As the chart moves and rotates, the line traced records the movements of floating carriage. Advantages Equipment suitable for mass production for inspection of gear.
