Heavy--duty car transmission shaft intermediate bearing rubber injection vulcanization formula

Abstract

The invention discloses a heavy-duty car transmission shaft intermediate bearing rubber injection vulcanization formula, and belongs to the field of car part processing. The heavy-duty car transmission shaft intermediate bearing rubber injection vulcanization formula mainly comprises natural rubber and an additive; the additive comprises an active agent, an anti-aging agent, a reinforcing agent, afilling agent, a plasticizer, an accelerant and a vulcanizing agent. By improving an existing heavy-duty car transmission shaft intermediate bearing rubber injection vulcanization formula, the time required by injection vulcanization is remarkably shortened, the production efficiency is effectively improved; and by taking the vulcanization process of a heavy-duty car support rubber part as an example, the output per shift is improved by 46.4% after adopting of the heavy-duty car transmission shaft intermediate bearing rubber injection vulcanization formula; the formula disclosed by the invention is more stable in the processing and using processes, and the product qualified rate in injection vulcanization process is improved.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a rubber injection vulcanization formula for the intermediate support of a transmission shaft of a heavy-duty vehicle. Background technique [0002] In the existing formula technical scheme for the intermediate support rubber part of the transmission shaft of a heavy-duty vehicle, many plasticizers with poor thermal conductivity are used in the components, and the thermal conductivity of the rubber is relatively poor. For heavy-duty brackets with larger rubber thickness, the vulcanization time is longer during vulcanization production. If the employees pause slightly during production, there will be insufficient vulcanization such as product bulges, and the vulcanization temperature is increased to reduce the vulcanization time. At this time, the rubber is prone to early scorch, resulting in low production efficiency and low product qualification rate. Contents of the inven...

Problems solved by technology

[0002] The existing formula technical scheme for the rubber part of the intermediate support of the transmission shaft of a heavy-duty vehicle uses more plasticizers with poor thermal conductivity in the components, and the thermal conductivity of the rubber is poor.

For heavy-duty brackets with larger rubber thickness, the vulcanization time is longer during vulcanization production. If the employees pause slightly during production, there will be insufficient vulcanization such as product bulges, and the vulcanization temperature is increased to reduce the vulcanization time. At the same time, the rubber material is prone to early scorching phenomenon, resulting in low production efficiency and low product qualification rate
