The use of wire rope hoist wire rope hoist is mainly used for all kinds of lifting, pull shift, handling heavy loads, tank welding wire rope hoist flip quotes, such as installation and removal of various medium-sized concrete, steel, and machinery and equipment, suitable for construction and installation of machinery and equipment companies, factories and mines of civil construction and bridge construction, electric power, shipbuilding, automobile manufacturing, construction, highways, bridges, metallurgical, mining, slope tunnels, wells and control protection, and infrastructure projects. Hoist spline shaft fracture analysis and improvement Second, an improved method to solve the broken shaft spline shaft problem md1 wire rope hoist, the use of units taken different measures for improvement, such as the spline coupling sleeve into a tire coupling or claw-type flexible couplings. In the heat treatment process will splined portion extends over the ending part of the heat treatment, both received good results. Figure 2 shows the structure of our plant improved. Our main ends of the spline shaft spline part into a flat key, and the shaft diameter and the other dimensions are unchanged. While the radius of the circle key shaft axis at the transition to R1.5, in particular to ensure that in the process. The left end of the motor shaft at the junction of the shaft, from the past to gear coupling sleeve splines. Thus, when the motor facilitate installation, the operation more convenient. And in operation on two different axes heart can get some self-adjusting compensation. However, the outer diameter of the inner-tooth gear coupling sleeve smaller diameter roller bearing bore dry inside. The right to install friction plate spline sets, only the inner bore spline into the corresponding one-touch connection, external dimensions and structural change. After improving the wire rope hoist suppliers, more than two years there has been no use of a phenomenon occurred off-axis. In short, for the type of electric hoist the original structure of the weaknesses in ensuring the transfer torque and in the original structure size allowed by the conditions, according to the processing characteristics of the unit, according to local conditions using different techniques to improve measures to address the broken shaft problem, in order to ensure the normal use of electric hoist.
