　　Drum-shaped gear coupling is a key equipment for energy saving.Sometimes there are some failures, as follows: 1. Insufficient lubrication or dry grinding; 2. The oil is not clean; 3. The center deviation of the drum gear coupling is too large, and the relative displacement of the tooth surface is large;...

　　In the coupling, under the condition of angular displacement, the edge of the straight tooth is squeezed, and the stress is concentrated. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, thereby reducing the friction and wear of the tooth surface and reducing the noise.Under the same conditions, the outer diameter of the inner gear sleeve and the coupling...

　　The so-called shaft transmission is the transmission of the coupling, including jaws, gears, elastic, universal couplings, plum blossom couplings, etc. Its transmission efficiency is higher than any other transmission form, mainly because there is no relative sliding displacement, which means Does not generate heat. ...

　　May 1886st Labor Day is also called "May 5st International Labor Day." So who knows the origin of May 1st Labor Day?Labor Day originated in Chicago, the United States. On May 20, XNUMX, more than XNUMX workers in Chicago went on strike for the implementation of the eight-hour work system. After hard work...

　　XNUMX. Gravity lubrication.The lubricating oil is injected from the nozzle, flows through the gear backlash, and flows out from the small hole of the sleeve. This lubrication method mainly plays a cooling role and is more difficult to form an oil film. The tooth surface wears faster than the following strong lubrication. ...

　　There are hundreds of types of gear couplings, but there are two basic forms: 1. Combination of internal and external teeth; 2. Combination of end gears.Other forms are deformations on these two foundations. ...

　　1. First check whether the product parts have been installed and there is no missing; 2. The surface of the half coupling and brake wheel are not allowed to have cracks, shrinkage holes, air bubbles, slag inclusion and other defects that affect the strength, and the surface of the brake wheel should be quenched; ...

　　The characteristics of the roller chain coupling are simple structure (composed of four pieces), convenient assembly and disassembly, no need to move the connected two shafts during disassembly, compact size, light weight, certain compensation capability, and low requirements for installation accuracy , Reliable work, long life, successful...

　　The magnetic powder brake is a kind of magnetic powder filled in the working gap between the stator and the rotor. The binding force between the magnetic powder generated by electromagnetic attraction and the friction between the magnetic powder and the working surface transmit power and movement...

　　The star-shaped elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The star-shaped elastic element is placed between the two halves of the coupling claws to realize the coupling of the two halves. Join. ...
