Precautions for the dismantling of the gear grinding machine coupling: Before the coupling is disassembled, make some marks for the position of the coupling parts between the couplings for reference during reassembly. For couplings used in high-speed machines, the coupling bolts are weighed, the markings must be clear, and the errors must not be made. The coupling bolts are generally removed first when the coupling is removed.
Before the coupling of the gear
grinding machine, it is necessary to make some marks on the positions where the components of the coupling cooperate with each other for reference during the reassembly. For couplings for high-speed machines, the coupling bolts are weighed and the markings must be clear and correct. When removing the coupling, the coupling bolts are generally removed first. Due to the deposition of a layer of grease, corrosion products and other deposits on the surface of the thread, it is difficult for the bolt to be disassembled, especially for bolts with severe corrosion. Disassembly is very difficult. The removal of the coupling bolts must be made with the right tool, because the stress surface of the outer hexagon or the inner hexagon of the bolt has been slipped and damaged, which is more difficult to disassemble. For bolts that have been rusted or have a lot of grease, the joint between the bolt and the nut is often sprayed with a solvent (such as a loose rust agent) to allow the solvent to penetrate into the thread, which is easy to disassemble.
By comparing and analyzing the main financial data of listed companies in the bearing sector at home and abroad, we believe that the three indicators of inventory, accounts receivable, net operating cash flow and sales revenue have certain warning significance. Foreign companies in this regard Control is more effective, resulting in higher operational efficiency and stable shareholder returns.
Multi-blade saw grinding machine manufacturer introduces the installation process of the gear coupling elastic coupling:
The flexible coupling is a new type of high-performance coupling developed by China. It concentrates on the advantages of different structures of the existing standard elastic couplings. For example, it has the advantages of a plum-shaped elastic coupling: the elastic element is compressed, the structure is simple and reliable. High sex. Overcome the shortcomings of the plum-shaped elastic coupling: when replacing the elastic element, the semi-coupling, the double-flange plum-shaped elastic coupling and the moment of inertia must be moved, and the application range is limited. When the same torque is transmitted, the radial dimension is much smaller than the GB4323 elastic sleeve pin coupling, the weight is light, and the moment of inertia is small.
Gear grinding machine elastic coupling has good compensation axial, radial and angular axis offset performance, good vibration damping performance, simple structure, stable and reliable work, no noise, no lubrication, simple maintenance, convenient loading and unloading, process Good character, low cost, can be derived into a variety of structural forms, good versatility, wide application range, easy to use, one of the advantages of the coupling is that it is only suitable for axis alignment, and the requirements are minimized. A working condition environment that assists in working hours.
Gearing machine flexible coupling is widely used in various fields of national economy. In addition to high temperature and high speed special working conditions, shafting transmission of various mechanical products can be applied. It can be applied to metallurgy, mining, lifting and transportation. , petroleum, chemical, ship, transportation, textile, light industry, agricultural machinery, printing machines and pumps, fans, compressors, machine reducers and other mechanical equipment. The industry shaft drive will gradually replace the widely used plum-shaped elastic joints. Shaft, elastic sleeve pin coupling, elastic pin coupling, elastic pin gear coupling, new elastic coupling, elastic coupling, roller chain coupling and gear coupling Corresponding specifications in standard couplings.
1. Carbide saw blades need to be repaired in time when the following conditions exist.
a) When the sawing quality no longer meets the requirements.
b) When the energy consumption of the sawing machine is significantly increased.
c) When there is a significant explosion at the edge of the cutting material.
d) It is very important to repair the sawtooth alloy blade when it wears 0.2mm in time. Because the blade with passivated edge is working, due to the increased resistance, it is easy to cause the saw blade to shake and increase the load of the motor. Both the saw blade and the machine can cause damage. Continue cutting at passivation, for every 10% increase in cutting, will result in an additional 50% alloy damage. Reduce the life of the saw blade.
Second, the multi-saw saw grinding machine manufacturers introduce the alloy sawtooth grinding
(1) The use of a precision, stable vibration-free sharpening machine, as well as a suitable diamond grinding wheel, to repair the alloy serrations according to the specified operating procedures will extend the life of the saw blade. If you use a manual sharpening device, you need to have a precise limit device and detect the end jump of the tooth tip.
(2) The resin, debris and other debris adhering to the saw blade must be cleaned with a cleaning agent before grinding.
(3) When sharpening, pay attention to the original geometric design of the saw blade. It is recommended to use the sharpening method of sharpening the rake angle and the back angle at the same time, which can increase the number of grinding times. Achieve a long service life.
