Mar 06, 2012· I have to check the shaftkey connection of a 3000kW 1000RPM asynchronous motor which is intend to drive a pump. When I compare the shaftend diameter with other motors (similar torque) the shaftend diameter is smaller. To be sure I want to check it. I have made some calculations as described in the DIN 6892.
Shaft mining or shaft sinking is excavating a vertical or nearvertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...

Shaft is a basic mechanical component. The concept of drive shaft design formula is explained in this article with an example shaft design can see a shaft in almost every machine, which has rotating parts. Typically a shaft has circular cross section. However, shaft with other cross sections find special application. We will discuss the design concept of a drive shaft subjected to ...

of the Mining Journal,, and many other members of the mining community, the Hard Rock Miner''s Handbook has been distributed to over 113 countries worldwide. Web hits and downloads continue as students and professors, miners, engineers, and mining executives embrace the Handbook as an invaluable source of practical
In this study, a new methodology for lining design of circular mine shafts in different rock masses is developed. A parametric study is carried out using the finite element numerical modelling of 2D shaft sections in a Hoek–Brown Medium in a nonhydrostatic stress state in an attempt to predict the pressures developing around mine shafts.
