Problems with the use of transfer cart
2017-12-15
There are some problems in the use of electric transfer cart. The common problems and analysis are as follows:
1. The vertical rotating deceleration device has the inconvenience of disassembly and disassembly, the boring and wear is serious, the load power is reduced, and the load load condition is allowed.Deviation analysis when the gear assembly, such as gear shaft on the aspect of minor deviations can result in unstable between gear meshing, no vibration, speed up the wear and tear, cause the gear failure, but we are using high speed gears and shaft one-piece structure, therefore, this factor can be ruled out almost;But reducer hot (i.e., heating and cooling process), in the process of meshing losses, bearing damage, stirring oil loss, seal damage, damage to the fan error produced a lot of heat, make the speed reducer is too high power loss and result in higher temperature, normal limit system function, has great influence on the speed reducer system, the full load power reduction.
2. Repair process: remove the difficult phenomenon, large area of the body were local deformation, the tray surface is damaged, unloading the difficulty is too large, below the retaining bolt remove the space is narrow, too many, part of the card phenomenon is more serious.It is difficult to remove the outer tooth retaining ring of the pallet bearing, which requires the welder to do the welding cutting, the cutting of the retaining ring loses the original size and the return loading condition.
3. The installation of the lift truck has used forklift fork movement, which has repeatedly appeared to be unable to fork;So for finished repair car body damage is very big, especially the friction wheel on the ground, because of its great weight, strong again, walking distance is far, and many other factors have directly flat wagon unnecessary damage.
4. Electric flat car wheel running mechanism of horizontal deflection value is an important technical parameter of electric flat transfer cart, will cause the deflection error gnaw rail, increase the running resistance, vibration and noise, intensify rail and wheel wear and greatly reduce the service life of the electric transfer cart, so all kinds of orbit transfer cart manufacturing technology conditions for the wheels, the value of horizontal deflection rules permit.The deflection value of wheel level is mainly based on different technical measures according to different product structure.More commonly used, process design structure is relatively simple: to wheel assembly of the wheel on a support group, such as Angle bearing box wheel set and bogie hearth 45 ° subdivision bearing box wheel group, on the track structure of flat owners, wheel lateral deviation after appropriate fixed to install.The disadvantage of this type of structure is that the wheel group of electric track flat wheels only has fixed wheels, and the wheels are difficult to adjust after installation.
