As is known to all, now use "forrest brand", "forrest card" y type hydraulic oil press is on the basis of the original zt hydraulic oil press.The gear box is still apply the original zt the design of the hydraulic oil press.When two stereotypes zt hydraulic oil press, China is in the period of economic recovery, steel strain, manufacturing industry is not developed, this brought some limitations to the design work, from the use of a few places exists obvious deficiency.palm oil processing plant
1 there is a problem
One is the input shaft bearings and the horizontal axis bearing service life is short;Two transverse strength is smaller, the structure is unreasonable, result in higher failure rate, two axis of normal working time between failures are difficult to achieve 5 000 h.We according to the input shaft bearing and the horizontal axis of the shorter service life of bearing, the bearing life calculation and the analysis of use conditions.
Original zt refined oil equipment passed 17 kW power, and "forrest brand", "forrest card" y refined oil equipment transfer power respectively 37 kW, 30 kW and transfer power increased by 76% and 117% respectively.In the case of a slightly smaller transmission torque, rotating speed is increased by 129% and 257% respectively 0 is obvious, and the service life of the bearing is inversely proportional to the speed of rise can lead to shorten the service life.
Two axis chosen is centripetal roller thrust bearing, the bearing in the process of operation, because the rolling element is the role of inertia moment, the sliding between the rolling element and raceway, lead to bearing heating, reduce the lubrication effect, draught fanthe rotation of the inertia moment is driven by two ring separate from each other.In order to guarantee the normal work of the bearing. Must make bearing axial load, in order to overcome the role of the moment, this is the use of this type of bearing is the most ideal situation.But the reality is that...
