What is the purpose of back gear unit in cone pulley headstock of a lathe?
Explanation: Back-gear mechanism is provided in cone pulley headstock to reduce the speed of spindle.
Why gear is used in lathe machine?
In lathe machine, spur gear pair in the gear box perform the most important mechanism of transmitting motion and power and reduction of the noise and vibration in this part can increase the production process and also high accurate jobs on lathe machine can be produced.
What does the headstock do on a lathe?
Headstock. Found on the end of the bed is the headstock. Once clamped to the end, the headstock provides the rotational power for the lathe’s operations. It contains the bearings used by the lathe to rotate the workpiece against the tool bit.
What type of gear arrangement is used to traverse the carriage in lathe machine?
The traverse rate of carriage on the bed is controlled by means of the gearing at the end of the bed in conjunction with the feed gearbox. Most of the latest types of lathes have the reversing mechanism built into the headstock and actuated by means of a separate lever.
What is back gear arrangement?
: the gearing at the headstock of a lathe for reducing the speed of the spindle from that of the driving pulley.
What is the purpose of back gear unit in?
As its name implies, “back gear” is a gear mounted at the back of the headstock that allows the chuck to rotate slowly with greatly-increased turning power.
What are lathe back gears?
“Back gears” are just what their name implies. A set of gears mounted at the back of the headstock on a lathe. Their purpose is to allow the lathe spindle to rotate at slower speeds while at the same time delivering greatly-increased torque.
What is reverted gear train?
When the axes of the first gear (i.e. first driver) and the last gear (i.e. last driven or follower) are co-axial, then the gear train is known as reverted gear trainas shown in Fig. We see that gear 1 (i.e. first driver) drives the gear 2 (i.e. first driven or follower) in the opposite direction.
What is gear cutting attachment for lathe?
Gear cutting is a specialized form of milling, and the lathe is quite suited to this job for smaller work (6″ diameter or so) with the help of attachment. The objective of this project is: Our project design and fabrication of gear cutting attachment is used to cut gear or splines over the cylindrical job.
What are the types of headstock in lathe?
Such as bed, headstock and tailstock etc. The headstock of an engine lathe is rigid in construction and has got an additional mechanism to get multiple spindle speeds. It has three types Belt-driven, Motor-driven, Gearhead type.
- 2.1 Belt Drive Lathe Machine.
- 2.2 Motor Driven Lathe Machine.
- 2.3 Geared-head Lathe Machine.
What is the use of lead screw in lathe?
A leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion.
Which of the following does headstock support?
The spindle is hollow in headstock and it is supported by the headstock.
What is the use of tumbler gear?
Tumbler gear mechanism is used to change the direction of lead screw and feed rod in lathe machines. By Engaging tumbler gear, the carriage can be moved automatically from tailstock end to headstock. End or moved from headstock end to tail stock end. E is the gear attached to the spindle.
Which of the following arrangement is used in the movement of carriage along the ways?
4. Which of the following arrangement is used in the movement of carriage along the ways? Explanation: Rack and pinion mechanism is used in movement of carriage by flywheel.
What is the function of carriage?
In its simplest form the carriage holds the tool bit and moves it longitudinally (turning) or perpendicularly (facing) under the control of the operator. The operator moves the carriage manually via the handwheel (5a) or automatically by engaging the feed shaft with the carriage feed mechanism (5c).
