Pulley and Gear

A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a cable or belt along its circumference.[1] Pulleys are used in a variety of ways to lift loads, apply forces, and to transmit power. In nautical contexts, the assembly of wheel, axle, and supporting shell is referred to as a "block." A pulley may also be called a sheave or drum and may have a groove between two flanges around its circumference. The drive element of a pulley system can be a rope, cable, belt, or chain that runs over the pulley inside the groove. Hero of Alexandria identified the pulley as one of six simple machines used to lift weights.[2] Pulleys are assembled to form a block and tackle in order to provide mechanical advantage to apply large forces. Pulleys are also assembled as part of belt and chain drives in order to transmit power from one rotating shaft to another.[3][4]

All Geared Lathe Vs Cone Pulley Lathe

All Geared Lathe Machine

Belt from one step to any other. All Geared Lathe have three or more than three shafts mounted
within & it is shown in the picture below.

All Geared Lathe Headstock View

The gears are equipped to obtain different speeds, which can be more than 18 spindle speeds. The
middle shaft has got three gears D,E & F as a single unit, thus will rotate at similar speed. The
spline shaft also have three gears mounted as A,B & C on it. The three gears can made to slide with
the help of the lever mounted in front of the Headstock as shown below.

All Geared Lathe - Preet Lathe Series

This movement enables the Gear A to contact with the Gear D or with other gears. This sliding
movement on the either of the shafts with the help of the levers, different gears get in touch with
each other & these gears are connected to the main Spindle. So, with the rotation of the Electric
Motor Pulley, these gears are also in drive and rotates the spindle, producing different RPM. All
Speed Changes are done with the series of levers on the front of the Headstock & are like shifting
gears in a Car.

Cone Pulley or V Belt Drive Lathe Machine


The V Belt Lathe Machine or famously known as Conventional Lathe Machine in Batala or Cone
Pulley Lathe Machine is one of the oldest form of the Lathe Machines, in which the different speeds
are obtained with the help of the belt arranged on the four different steps of the cone pulley. A
step Cone Pulley is attached with the Head Stock Spindle.

Cone Pulley Presentation

The Conventional Lathe Machine or Cone Pulley Lathe has four steps as in the above picture
(A,B,C,D) & on the other side there is another pulley which also have four steps (E,F,G,H) which is
placed parallel to the Spindle Cone Pulley. Both the Pulleys are connected with the Belt and the V
Belt is connected to the Electric Motor. The Belt can be arranged between the steps A&H, B&G,
C&F & D&F manually, thus the required speed is attained. The Spindle speed will be maximum
when the belt is arranged between A & H while the minimum speed will be attained when the belt
is arranged between D & E. In this kind of Lathe, Operator have to slip the Belt from one step to
another manually.
