Jute Bags – Various Types

Designer Jute Bags
Jute bags are monumental for a number of reasons and advantages. They are light weighted, durable, versatile, eco friendly and comes in a wide variety. The jute bags manufacturers provide jute bags with embroidered pattern all over which makes them perfect to gift to loved ones. However, the printed jute bags are most common and can be found easily from local shops. Some common types of jute bags are listed below,

1) Jute Shopping/Grocery Bags – These bags are durably made to last for a long time. These shopping bags come in comparatively large size with a small pocket inside and zip closure to protect the items.

2) Ladies Bags
– These bags come in many vibrant colors, lovely prints and various styles to match the latest fashion trend. A wide collection of handbags, wallets and clutch bags of jute are available with multiple pockets and great versatility.

3) Tote Bags – Made to hold multiple items, such bags come in relatively large size with elegant prints and bold colors.

4) Sling Bags
– Small in size with multiple mini-pockets, such bags are widely demanded for both men and women. These bags are generally used for carrying important items like wallets, card holders, camera, specs, goggles, phone with charger, pocket mirror, sanitizers and more.

5) Gift Bags – Gifting a gift to loved one in a bag looks more presentable and nice. A nice collection of attractive jute bags are available which make best for gifting.

6) Travel Bags – Jute Backpacks and jute travel bags which are designed for traveling purpose are available in the markets. These bags have enough space, multiple pockets, zip and buckle locks and more strength with trendy and fashionable looks.

7) Promotional Bags – Many companies use jute bags for promoting their organization. Such bags have printed company's name, logo, address with a promotional message on them.


8) Multi-utility Bags
– Various sizes of jute bags are available that can be used for different purposes. These bags are suitable for carrying laptops, books and many more.

On A Friendly Note ..!
No doubt, jute is 100% biodegradable material which cause no harm to environment while processing and manufacturing products from it. Also, the cost of producing jute bags is comparatively lower than plastic, paper and cloth bags. Thereby making them completely safe to use and economical in terms of price.

Reduction Gear Box – Application and Types

Gearboxes are widely accepted mechanical device of transmitting energy from one device to another. Gearboxes are installed for increasing torque and controlling turn movement while reducing speed in mechanical drive systems. In today's engineering, reduction gear box are widely used in automobiles and two wheelers, heavy duty tools and machines even in ships and some electrical appliances to control the mechanism.
reduction gear box

The entire framework of gearboxes consists of a set of rotating gears and shaft which are connected to wheel works. This mechanism serves the basic purpose of slowing down the speed or machine to increase the torque within system so that transfer of energy can take place from one place to another.

Composition Of Reduction Gearbox

Gearboxes are simplified engineering component that are basically configured in the inner workings of motors, machines or other mechanical component. The simplified version of reduction gear consists of a set of gear having same size of teeth with different diameters.

While designing a balanced correlation between teeth and circumference of gears is maintained; the smaller gear with small circumference will have fewer teeth than of other gear. When these gears mesh with each other in a gearbox, then the smaller gear makes one extra revolution with that of larger one. In other words, the small gear spins twice as fast as the large gear. This systematic operation of gears product twice amount of torque on the larger shaft than on the smaller; as the decrease in output speed generates an increased amount of torque.

Varied Types of Reduction Gearbox

Engineering component which uses high rotational speed in one part of design as well as needs reduced energy in another component within internal system; make use of reduction gearbox. This reduction in speed thus create the increased torque on the output shaft. There are mainly two types of reduction gears which are used while designing automobiles and mechanical machines. They are,
 
  • Single Reduction Gear – In this arrangement, only one pair of gears are used in the assembly of reduction gearbox. There are ports to connect the propeller shaft and engine shaft with assembly. Engine shaft drives the pinion (smaller gear) which in-turn drive the larger gear mounted on propeller shaft.
  • Double Reduction Gear – In this arrangement, flexible coupling is used for connecting pinion with input shaft. There is an intermediate gear (first reduction gear) primarily connected with pinion. The first reduction gear is further connected with a low speed pinion via another shaft. To facilitate the speed reduction ratio as high as 20:1, an another reduction gear is used. The low speed pinion connects the second reduction gear with propeller shaft.
The application of double reduction gears are confined to engineered components involving high speed application.

Reduction Gearbox – Wide Application


Reduction gearboxes find their wide application in the drive-trains of automobiles to reduce the high rotational speed of the engine so that the tires can safely use the reduced speed. The same set of configuration is used in heavy machinery and mechanical appliances for reducing speed and increasing torque.
In industry, reduction gearboxes are used in Cranes, Elevators, Crushers, Conveyors, Industrial Mixers, Cooling Towers, Agitators, Extruders and many more.
