摘要
原 RH真空室烘烤装置升降小车采用齿轮齿条传动方式或链轮链条传动方式 ,都曾多次发生事故 ,改用液压推杆——链条传动方式后使用效果很好。
Many accidents occur on the original rise-fall vehicles of the roast device in RH vacuum chamber, these vehicles used gear-rack drive or sprocket-chain drive. But better effect can be brought by using hydraulic rod-chain drive.
