Problems solved by technology

[0002] During the use of the existing chain, there are the following problems: First, the problem of heat accumulation is prone to occur. During the use of the existing chain, it takes 160 seconds for the temperature to rise from normal temperature to 150°C, and then rises slowly, up to 300°C. ℃, the chain will be annealed and the hardness will be reduced; secondly, its average service life is 85-90 hours, if it exceeds 90 hours, the drive plate will be severely deformed due to wear, and continued use may cause the chain to break; finally, during the rotation of the chain , the lubricating oil filled from the oil hole of the guide plate is difficult to cover and remain on the surface of the chain. As the temperature of the chain rises, the oil layer on the surface dries quickly, resulting in aggravated chain wear
[0003] To sum up, the existing chains have the problems of short service life, high cost of use, and high risk factor

Embodiment 1

[0017] A chain drive piece, on which two through holes 1 are opened, and the two through holes 1 are used to cooperate with the small holes opened on the blade, and the through holes 1 are riveted with the small holes on the blade by using rivets, so that the blade It is connected end to end with the transmission sheet to form a chain, and several cooling holes 2 are opened on the transmission sheet, and all the cooling holes 2 are equal in size and evenly distributed.

[0018] The existence of heat dissipation holes 2 can assist heat dissipation. During the use of embodiment 1, the temperature rises from normal temperature to 1

[0019] It takes 350 seconds at 50°C, and then rises slowly, up to 280°C, so that the chain will not be annealed, the hardness will not decrease, and the service life of the chain can be increased; secondly, its average service life reaches more than 115 hours, and the transmission of more than 115 hours The degree of wear of the sheet can still ensur...

Embodiment 2

[0021] A chain drive piece, on which two through holes 1 are opened, and the two through holes 1 are used to cooperate with the small holes opened on the blade, and the through holes 1 are riveted with the small holes on the blade by using rivets, so that the blade It is connected end to end with the transmission piece to form a chain, and a cooling hole 2 is opened on the transmission piece, and the cooling hole 2 is opened in the middle of the transmission piece 1 .

[0022] The existence of heat dissipation holes 2 can assist in heat dissipation. During the use of Example 2, it takes 350 seconds for the temperature to rise from normal temperature to 150°C, and then slowly rise to a maximum of 280°C, so that the chain will not be annealed and the hardness will not decrease. It can increase the service life of the chain; secondly, its average service life reaches more than 115 hours, and the wear degree of the transmission plate exceeding 115 hours can still ensure that the ch...

technical field [0001] The invention relates to a chain transmission piece. Background technique [0002] During the use of the existing chain, there are the following problems: First, the problem of heat accumulation is prone to occur. During the use of the existing chain, it takes 160 seconds for the temperature to rise from normal temperature to 150°C, and then rises slowly, up to 300°C. ℃, the chain will be annealed and the hardness will be reduced; secondly, its average service life is 85-90 hours, if it exceeds 90 hours, the drive plate will be severely deformed due to wear, and continued use may cause the chain to break; finally, during the rotation of the chain , the lubricating oil filled by the oil hole of the guide plate is difficult to cover and remain on the surface of the chain. As the temperature of the chain increases, the oil layer on the surface dries quickly, resulting in aggravated chain wear. [0003] To sum up, the existing chains have the problems of ...
