wherein the inner chain plate and the outer chain plate are respectively toothed chain plates.
The inner chain plate and the outer chain plate are tooth-shaped chain plates, noise generated in the engagement process is relatively low because of the difference of the states of the teeth in the engagement process with the chain wheels, and noise of the whole running of the chain can be maintained at a low level because the inner chain plate and the outer chain plate simultaneously participate in the engagement with the chain wheels, and the meshing states of the upper teeth of the inner chain plate and the upper teeth of the outer chain plate and the chain wheels are also different.
The arrangement of the lubrication cavity can construct a reliable lubrication environment in the chain so as to adapt to the working condition without lubrication and obtain higher working rotation speed. And the arrangement of the sealing ring can reduce the leakage of lubricating grease and improve the service life of the chain.
Preferably, a sleeve is arranged between the inner chain plate and the pin shaft, the sleeve is in interference fit with the inner chain plate, and a lubrication cavity is formed between the sleeve and the pin shaft.
The sleeve is arranged to ensure the contact area between the inner chain plate and the pin shaft, and improve the loading condition of the pin shaft in the operation process.
Preferably, the number of the inner link plates is at least two.
Preferably, an outer guide plate is further arranged on the outer side of the outer chain plate, and the outer guide plate is in interference fit with the pin shaft; the outer guide plate covers tooth grooves of the outer chain plate on the side face.
The outer guide plate can play a role in lateral fixing and guiding, so that the lateral separation of the chain and the chain wheel is avoided, and the reliable engagement of the chain and the chain wheel is ensured.

Description of the embodiments
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Examples
As shown in fig. 1-6, a sealed mute chain comprises a plurality of inner chain plates 2, wherein two adjacent inner chain plates 2 are connected through an outer chain plate 1 and a pin shaft 3. As shown in fig. 7 and 8, the inner link plates 2 and the outer link plates 1 are tooth-shaped link plates, respectively. The outer chain plate 1 is in interference fit with the pin shaft 3, as shown in fig. 5, a lubrication cavity is arranged between the inner chain plate 2 and the pin shaft 3, and lubricating grease is filled in the lubrication cavity. The number of the inner link plates 2 may be single or plural.
As shown in fig. 5, specifically, a sleeve 6 is arranged between the inner link plate 2 and the pin shaft 3, the sleeve 6 is in interference fit with the inner link plate 2, and a lubrication cavity is formed between the sleeve 6 and the pin shaft 3. The sleeve 6 can ensure the contact area between the inner chain plate 2 and the pin shaft 3, and improve the loading condition of the pin shaft 3 in the running process.
As shown in fig. 5 and 6, the novel hinge assembly further comprises a sealing ring 5, wherein the sealing ring 5 is sleeved on the pin shaft 3 and is positioned between the inner chain plate 2 and the outer chain plate 1, and the inner chain plate 2 and the outer chain plate 1 jointly compress the sealing ring 5.
As shown in fig. 1-6, an outer guide plate 4 is further arranged on the outer side of the outer chain plate 1, and the outer guide plate 4 is in interference fit with the pin shaft 3; the outer guide plate 4 laterally covers the tooth grooves 11 of the outer link plate 1. The outer guide plate 4 can play a role in lateral fixing and guiding, so that the lateral separation of the chain and the chain wheel is avoided, and the reliable engagement of the chain and the chain wheel is ensured.
The inner chain plate 2 and the outer chain plate 1 are both toothed chain plates, and because the states of the teeth in the process of meshing with the chain wheels are different, the noise generated in the meshing process is relatively low, and meanwhile, because the inner chain plate 2 and the outer chain plate 1 participate in the meshing with the chain wheels at the same time, the meshing states of the upper teeth of the inner chain plate 2 and the upper teeth of the outer chain plate 1 and the chain wheels are also different, the noise of the whole running of the chain can be maintained at a lower level. The noise reduction of the toothed chain plate is the prior art in the field, so the principle of noise reduction of the toothed chain plate is not repeated here.
The arrangement of the lubrication cavity can construct a reliable lubrication environment in the chain so as to adapt to the working condition without lubrication and obtain higher working rotation speed. And the arrangement of the sealing ring 5 can reduce the leakage of lubricating grease and improve the service life of the chain.
In summary, the foregoing description is only of the preferred embodiments of the utility model, and is not intended to limit the utility model to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
