The cross-sectional shape of the retaining ring is generally rectangular. The retaining ring of this shape is limited in the sealing structure. It protects the sealing ring and does not participate in the sealing effect.
The capped nut can prevent the bolt connection from directly contacting with the outside world, which is corroded and makes it difficult to disassemble later. Nuts with caps in the prior art are mostly of one-piece structure, and the surface is not treated with anti-oxidation, which is easy to be corroded. In addition to the protective effect, the fastening method is the same as that of ordinary nuts, so it is easy to loosen when subjected to severe vibration. .
When using a rivet nut, drill a hole corresponding to the outer diameter of the rivet nut on the thin wall, then place the rivet nut on the bolt of the special rivet gun, push the handle to screw in the rivet nut, and put it into the drilled hole. In the workpiece, squeeze the handle, the rivet nut expands, and the deformed skirt bulges and deforms. At this time, the workpiece is tightened. After riveting, the handle is pulled out, the bolt is released from the rivet nut, and the corresponding screw is screwed into the rivet nut threaded hole. , forming a tight riveted body.
A crank press with bilateral transmission, such as a briquettes machine, requires 1. The rotation phase of the main shaft gears on both sides must be consistent; 2. The connection between the main shaft and the main shaft gear should be free of gaps. In order to meet this requirement, there are mainly two schemes for the connection between the main shaft and the main shaft gear. Option 1, one or both ends of the main shaft and the main shaft gear are connected by flat keys. This scheme requires that the matching clearance between the main shaft and the gear hub is small, so it is difficult to process, assemble and maintain; Option 2, one or both ends of the main shaft and the main shaft gear Using taper-sleeve connection, this solution has good performance, but high cost and poor rigidity
Nut fasteners are used in various industries with connection and fastening requirements, such as vehicles, construction machinery, agricultural machinery, manufacturing machinery, etc. For large construction machinery or construction vehicles, due to the harsh working environment and the action of heavy loads, the nut fasteners on it are subjected to vibration and load impact in all directions, which makes the nut easier to loosen, resulting in tightening. The function of the device is reduced or even failed. cause a great safety hazard.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: cassette nuts, plum blossom retaining rings, multi-tooth K-shaped hexagonal teeth with teeth, split B-type pins and other products, we can provide you with The right fastener solution for you.
