Description
Technical Field
The utility model relates to the technical field of mechanical equipment couplings, in particular to a high-torque low-noise internal tooth coupling capable of being longitudinally installed.
Background
At present, most of conventional internal tooth couplings are installed transversely. Because the structures of the tooth parts at the two ends of the internal tooth coupler are open, no sealing part exists, the internal tooth coupler is often influenced by other pollutants such as oil, water, dust and the like when being longitudinally installed and used, the service life of the internal tooth coupler is greatly reduced, and the noise is relatively large.
Meanwhile, the outer gear sleeve of the conventional internal gear coupler is made of non-rigid materials such as nylon, the torque transmitted by the coupler is small, and the coupling is only suitable for some occasions with low torque. In some occasions where the transmission torque is large and longitudinal installation is required, the conventional internal tooth coupler cannot meet the practical installation and use.
Therefore, we propose a high torque low noise internal tooth coupling that can be longitudinally mounted so as to solve the problems set forth above.

Preferably, the outer gear sleeve of the coupler is made of a rigid material.
Preferably, the oiling structure comprises a threaded hole formed in the outer gear sleeve of the coupler and an oiling nozzle arranged in the threaded hole.
Compared with the prior art, the utility model has the beneficial effects that:
1. the sealing ring, the sealing gland and other sealing components prevent the inside of the coupler from being influenced by other pollutants such as oil, water, dust and the like during longitudinal installation, thereby meeting some occasions needing longitudinal installation and prolonging the service life of the coupler;
2. The outer gear sleeve of the coupler is made of rigid materials, the torque transmitted by the coupler is larger than that transmitted by the coupler which is made of non-rigid materials such as nylon and the like, and the coupler also meets certain mounting occasions with higher transmission torque;
3. The structure of oiling has been increased to the shaft coupling external tooth cover, after the installation of shaft coupling internal tooth axle sleeve, the accessible oiling mouth is with the inside of lubricated, noise reduction's oil injection to the outer tooth cover of shaft coupling, fully lubricate tooth portion and fill the clearance of shaft coupling tooth portion, greatly reduced the phenomenon that produces great noise when the internal tooth shaft coupling uses.
