A typical Eccentric part : First a piece of bar was turned to the required outside diameter (22mm in this example). The length of bar reduced to this diameter was long enough give the chuck something to grip in the next step. This diameter often forms the working surface of an eccentric so time was taken to get a running fit in the mating part.
What is claimed is: 1. A method of manufacturing a drive shaft for use in a scroll compressor comprising the steps of: forging a metal bearing cap for receiving a portion of an orbiting scroll to impart an orbiting motion thereto; fixedly securing said metal bearing cap forging to a steel tubular rotor shaft; and.
Turning an Eccentric with Close Center Holes If turning an eccentric that has the different centers placed too close together, a different procedure should be used. Cut the stock 3/4 inch oversized and just face both ends to clean up the saw cuts Lay out and center-drill the normal. center axis and turndown those diameters on the center axis with the work mounted between centers.

Nov 04, 1980· An eccentric shaft particularly for driving a large reciprocating pump, and a method of making the shaft. The shaft includes an elongated cylindrical body, a plurality of small eccentric discs uniformly spaced along the length of the body, and optionally one or more concentric gear flanges, all formed as a single integral forging.
Sep 19, 2016· There are 7 kinds of clamping method of turning eccentric parts. 1. With four-jaw chuck turning This method is suitable for processing eccentricity smaller, less precision, shorter and smaller quantity of eccentric parts. 2.With three-jaw self centering chuck turning
A simple degree wheel of printed paper. This one looks like it was made for camshaft and other engine timing. Rotate to the appropriate degrees, use the cross slide to set the offset, and fire the prick punch Now the wobbler is set up on one of the punch marks and Hillmar can dial in the 4

Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates.
Sep 19, 2016· In mechanical transmission, the rotary motion into reciprocating linear motion or linear motion into rotary motion, usually with an eccentric shaft or crankshaft to complete.Eccentric shaft that is parallel to the axis of the parts between the cylindrical outer and without overlap. The method of turning eccentric parts,according to different quantity,shape and precision of the machined parts
Mar 23, 2012· Downeast Machine's Customer required a brand new shaft after there's had been cracked through prolonged use. here is a video showing the process of making th...
Nov 04, 1980· An eccentric shaft particularly for driving a large reciprocating pump, and a method of making the shaft. The shaft includes an elongated cylindrical body, a plurality of small eccentric discs uniformly spaced along the length of the body, and optionally one or more concentric gear flanges, all formed as a single integral forging.
Eccentric-and-rod mechanism, arrangement of mechanical parts used to obtain a reciprocating straight-line motion from a rotating shaft; it serves the same purpose as a slider-crank mechanism and is particularly useful when the required stroke of the reciprocating motion is small in comparison with the dimensions of the driving shaft. In the figure, the eccentric disk 2 is fixed off centre to
Homemade Eccentric Shaft Cutting Method homemadetools.net. Lathe Tips: Eccentric Turning. As in turning on a lathe with the workpiece not concentric with the spindle axis. This is a common need when building engines, for example, to machine the throws of a crankshaft, or the eccentric drive used by a steam engine to operate a slide valve.
Forged Step Shafts, Eccentric Shafts & Rotor Shafts Guaranteed Sound-Centered Forged Shafts & Spindles. Scot Forge produces guaranteed sound-centered forged step shafts and rotor shafts from ferrous or non-ferrous materials with any combination of round, square, rectangle or polygonal dimensions, concentric or eccentric configurations, and tapers or custom shapes.
Jun 01, 2016· This is the most popular mounting method. Note: Setscrews can cause significant fretting corrosion, making removal very difficult after years of operation. ECCENTRIC LOCKING COLLAR How it works: As the collar is twisted into place, it locks the bearing to the shaft. The contact of the bearing is slightly more distributed than the setscrew
Overview. All types of machines having shafts as an integral part of their structure, experience problems related to shaft alignment. Shaft alignment is a method or procedure by which shafts of machines such as motors and turbines are connected to a generator or pump in proper alignment. Improper alignment leads to increase of stresses in the shafts and thus on the equipment, which might
In mechanical engineering, an eccentric is a circular disk (eccentric sheave) solidly fixed to a rotating axle with its centre offset from that of the axle (hence the word "eccentric", out of the centre).. It is used most often in steam engines, and used to convert rotary into linear reciprocating motion to drive a sliding valve or pump ram. To do so, an eccentric usually has a groove at its
Inspectex the eccentric shaft sensor and found oil seeping through the plug, I replaced the sensor, put on the ignition for 20 secs, locked the car for 5 mins, started up and drove for 150kms and engine light came on. Same fault codes. I inspected the ECU connection plugs and found the plug had some oil at termenals, not sure how it got there
In this study, the non-rotating mode shapes, natural frequencies of eccentric shaft are used in a modal analysis method for calculating the dynamic characteristics. Nowadays, modal analysis has become a useful tool for studying the dynamical behavior of complex mechanical structures [ 3 ] .
The fifth variation shown by NFL athlete Julian Williams involves the brutal manual eccentric tension method shown above. Just make sure to communicate with your partner regarding the level of tension needed during the set. Lastly, the sixth variation I show involves the eccentric KBox flywheel method which produces inordinately high levels of
