A cam follower, also known as a track follower, [1] is a specialized type of roller or needle bearing designed to follow cam lobe profiles. Cam followers come in a vast array of different configurations, however the most defining characteristic is how the cam follower mounts to its mating part; stud style cam followers use a stud while the yoke style has a hole through the middle.
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
The cylinders have steel barrels with aluminum heads, and the valves are operated by hydraulic lifters. The crankshaft is supported in an aluminum-alloy split case by four main bearings and one ball-thrust bearing, and lubricating oil is supplied from a 12 quart wet sump. The camshaft rides in journals that do not employ bearing inserts.
The camshaft has three camshaft bearings. A lid made of cast iron covers the camshaft spur gears; the ignition distributor is placed on top of this lid and is driven by the camshaft spur gears. For powering the fuel pump, the camshaft is fitted with an extra cam located in the bearing on the flywheel side. [11]
The 1340cc Evolution utilizes a single, four-lobe, gear-driven camshaft located just above the crankshaft axis. While this simplifies camshaft replacement, it complicates the Big Twin valve train with tappet/lifters and pushrods that each deflect from the camshaft at wildly different angles. The Big Twin pushrods have a distinct helical ...
Mastercam is CNC Software's main product. It started as a 2D CAM system with CAD tools that let machinists design virtual parts on a computer screen and also guided computer numerical controlled (CNC) machine tools in the manufacture of parts. Mastercam has been ranked by CIMdata Inc. as the most widely used CAM package in the world since 1994. [2]
