What is the sun shaft of travel final drive and what it’s used for ?

What is the sun shaft of travel final drive and what it’s used for ? : Sun shaft is travel final drive  element in the planetary gearbox . . On the top of sun shaft there is a gear which transfers power from travel motor to gearbox which  puts the entire transmission in motion. At

What is the travel motor shaft and what it’s used for ?

WHAT IS THE TRAVEL MOTOR  SHAFT AND WHAT IS IT FOR? The travel motor shaft is an element of the excavator drive system. It transmits the drive directly from the piston pump to the gearbox, where it connects to the sun shaft (described in another article). The motor shaft on its length has two types

Travel final drive bearing – Use for what ? Why so expensive?

Bearings of travel final drive usually are angular contact which  task is to minimize the friction resistance during work of the planetary gearbox Bearings installed in excavators  of 1.5-50 tone weight  are usually divided into two types: tapered roller bearings and angular contact bearings The angular contactor bearing is constructed in such a way that

Regeneration of radiators – repairs

Regeneration, slow down what and how? You’ve come across this article because you’re probably looking for information on one of two things, namely: can you regenerate your gear and how much it will cost. Well, each planetary gear can be repaired. The renovation of one will last for a few days, another for a few

Planetary gear housing regeneration of planetary gears

Regeneration of planetary gears General news Planetary gears are widely used in general mechanization, from the construction industry through transport and agriculture. 99% of crawler machines for driving drive use planetary gears, which is why “regeneration” is popular. Speed reduction systems of this type are very simple and also very durable. However, every user of

Guide for the operator: how to avoid failure of the hydromotor-reducers

The hydromotor, like any of the operators, consists of two parts. Namely, from a hydraulic engine and a rotational speed reducer, i.e. a planetary gear commonly known as a hub reduction gear. The driving engine itself does not fail as such. This engine has it to itself, it just consumes and depending on the level

Guide: disassembly and assembly of the driving hydromotor

We know very well that for some people the dismantling of the hydromotor with the gear is first because each of us had to start their adventure with machines. What is it going with the problems related to their exploitation. Therefore, we present a simple guide on how to effectively dismantle the device so that
