Importance of transmission parts in drum gear coupling machinery

Importance of transmission parts in drum gear coupling machinery

Drum gear couplingThe key to the selection takes into account the height of the required transmission shaft speed ratio, the size of the load, the installation precision of the two connected components, the stability of rotation, the price, etc., refer to the characteristics of various couplings, and choose a common one. Coupling type.Couplings are mechanical parts used to connect two shafts (gear shafts and driven shafts) in different tissues to each other to transmit torque. In a high-speed and light-load driving force transmission system, some couplings The device also has the functions of buffering, damping and improving the dynamic characteristics of the shafting.

The coupling consists of two parts, each connected to the gear shaft and the driven shaft. Generally, most engines are connected to the working machine by means of a coupling.The size of the coupling transmission equipment for mechanical equipment, that is, the larger axial and shaft diameter specifications, must be within the installation room space allowed by the mechanical equipment.The coupling transmission equipment for mechanical equipment should be selected that is convenient for assembly and disassembly, no maintenance, long maintenance time or convenient maintenance, disassembly and replacement of parts without moving the two shafts, and easy centering adjustment.It is difficult for large and medium-sized machinery to adjust the alignment of two shafts. It is necessary to choose coupling transmission equipment for machinery that is durable and convenient to replace and replace parts.Coupling transmission equipment for flexible mechanical equipment with ductility of metallic materials generally has a longer service life than coupling transmission equipment for flexible mechanical equipment with non-metallic materials.Coupling transmission equipment for mechanical equipment that requires sealing and lubrication and impervious application durability will definitely increase the amount of maintenance labor.


For places with long-term continuous operation and high economic benefits, such as the high-speed end of the extruder transmission device of my country's metallurgical industry company, coupling transmission equipment for gear machinery and gear machinery are widely used at this stage. Although the transmission torque of the coupling transmission equipment is theoretically large, it must be durable under the standard of good lubrication and sealing.In addition, it is necessary to frequently check the sealing condition, inject lubricating grease or lubricating grease, the maintenance labor is heavy, the auxiliary construction time is increased, the reasonable working time is reduced, and the economic benefits of production are endangered.

Internationally, industrial production capitalist countries have generally adopted pulse damper couplings that have a long service life and do not require lubrication and maintenance to replace drum-type gear mechanical equipment with coupling transmission equipment. This not only improves economic benefits, but also Can clean the office environment.The extruder transmission device adopts the coupling transmission equipment for malleable movable pin mechanical equipment and the coupling transmission equipment for fan-shaped block ductile mechanical equipment developed in our country, and not only the coupling for pulse damper mechanical equipment, is provided. The advantages of transmission equipment, and the buffer shock absorption effect is very good, the price is more cost-effective.
