The Doosan top roller is part of the moving part of the Doosan track. Its purpose is to ensure minimum sagging of the upper part of the Doosan track. Doosan top rollers are made of steel and are used to support the upper section of the track in the track chassis, which includes several supporting Doosan top rollers. They are located on the carrier, respectively, are installed on both sides, between the Doosan drive and return wheels. The Doosan top roller for supporting the tracks and chassis includes a bearing block with a roller. This mechanism, which has the ability to rotate, connects to the suspension unit suspension Doosan undercarriage.
The Doosan top roller (Doosan roller, Doosan upper roller) is a Doosan track element designed to support the upper part of the Doosan track and to facilitate tension that reduces sagging. The use of a lot support rollers reduces the force necessary for pulling the track. Also, Doosan rollers prevent Doosan strikes on the frame and give the tra
Doosan Bottom Roller is a crawler drive element that is a movable support for a Doosan equipment (a tractor, bulldozer, excavator, etc.) that use Doosan track chains. The part is to be installed with Doosan bearings on the axles to the suspension of the running gear.
Doosan bottom rollers are mounted on bearings on axles that are connected to the body through a suspension. In order to mitigate impacts on the Doosan during the movement in a rough terrain, the Doosan rollers are usually made rubberized. It can also be made of composite materials. Doosan bottom rollers have an internal design based on a coil or cylindrical roller bearings. Thick-walled outer ring allows to withstand high radial loads.
Types of Doosan Bottom Rollers:
- Not rubberized;
- Rollers with internal cushioning.
Doosan Bottom roller supports the following functions:
- Improvement of the rotating Doosan track chain;
- Reduction of noise generated between the Doosan track chains
Doosan track shoe - an integral part of the crawler chain Doosan construction machines on equipment such as excavators, lifting machines, bulldozers, tractors and more. Designed to reduce the specific pressure of the weight of the base machine on the surface, which ensures patency on weak soils. To work equipped with rubber Doosan tracks in urban areas, reducing noise and damage cover (asphalt, concrete and so on). For work in wetland conditions, arched track shoes are used.
The Doosan shoe track is one of the components of the Doosan track. Doosan shoes tracks are cast or forged units of wear-resistant steel, having on the outer surface of the lugs on the inner surface - the guide ridges, and apertures which include the teeth of the drive wheels, and lugs, which includes connecting pins pivotally connecting the tracks with each other. According to the constructive implementation of the Doosan links, there are composite and integral castings.
At present, several dozen types of Do
The Doosan track chain is an important part of the Doosan track, it consists of movable elements that are connected together by means of fingers and bushings. It is this part that comes into contact with the ground surface during operation and exerts pressure on it. Using a crawler chain allows you to reduce pressure on the soil, which increases the throughput of Doosan Heavy Equipment.
The Doosan tracks consist of bushes into which the fingers are placed, so joints are formed, allowing the chains to fit tightly the guide and the driving wheel.
Like any other equipment, the Doosan equipment, over time, requires replacement of worn out Doosan parts. If you need to replace spare parts like Doosan track chains, you should pay attention to such moments: the length of the crawler chain and the diameter.
The Doosan track chain can be mounted on motor grader, tractor, bulldozer and excavator Doosan. Such products are characterized by a long operating term, as well as a high level of
